[Q] attempted kitkat revert, almost completely unresponsive - Nexus 7 (2013) Q&A

I have a bone stock 2013 Nexus 7 32 Gb Wifi, never had a problem with it. A few weeks ago, it notifies me of an update (Lollipop) so I apply it. Nothing but problems since then. It was very laggy and would glitch every few seconds while playing video (either local files or streamed over Plex, both had same issue). Sometimes when I'd wake it from sleep, the screen would look like an old CRT TV with static (except it wasn't moving, it was a fixed image). It would hang like this for seconds or sometimes minutes. Rebooting would usually resolve this for a while.
Tried a few 'lollipop tuning' tweaks, but when these failed to fix the video glitching and lagginess, I decided to revert to kitkat and followed an online tutorial (exactly like the one here except it had me install a standalone ADB/fastboot instead of full SDK) . No problem installing USB driver or setting nexus into USB mode. No problem getting it into fastboot mode and "fastboot devices" correctly listed the device, and "oem unlock" appeared to work fine as well. Running the flash-all batch file also seemed to go normally. But now my device is even worse than before:
- won't boot/run normally... no boot-up logo or video ever displays (or if it does, it's just a partial static image). Appears to get to a 'welcome' screen but the display is all messed (part of the screen is just repeated several times, so you can't see the entire screen). Unresponsive to touch, though it will make some sounds when you press in certain areas, but the display never changes. If I sleep it and wake it up, it shows the 'CRT static' mentioned above for many seconds before showing slowing showing the tiled/corrupted welcome screen. I can access the nexus' file system over USB on my PC even while it's in this borked state.
- display is now blank when getting into fastboot mode... i can time pushing the down-volume and power button so I know I am in fastboot mode ('fastboot devices' correctly lists the device) but the display is now completely black (not on, no backlight) in this mode.
I tried flashing to factory 4.4.4, 4.3, and 4.2 (always using 2013 wifi images) and it doesn't make a difference. Same results. Is there some bit of code that doesn't get reflashed during this reset that could explain why I'm having these issues? Any advice how to fix?

So your bootloader is blank right? I would flash a new bootloader asap! And see if that fixes anything

I have to confess my ignorance here... I'm brand new to flashing android like this so I don't know the answer to your question. If part of tutorial I followed blanks out the bootloader (and doesn't write something in?)... then you're probably right. I shall look into this more tonight when I'm at home with the nexus. Thanks for at least giving me something to look into, that's exactly what I was hoping for!

This sounds more like a hardware issue than software to me. See if you can get a warranty repair or replacement.

Thanks, you're probably right. I did read up to understand all this stuff a bit more, so I know it's not lack of a bootloader or anything. All img files install just fine, so my pc can talk to the nexus, just the screen is all wonky no matter what i do.
Unfortunately I bought this 1.5 years ago so I don't think it's under warranty anymore. Everything was fine until I updated to Lollipop! Seems a big coincidence that I had a hardware failure at the same time as that update... I feel like Google ruined my tablet...

There is a bug where sometimes when you unlock the bootloader it zeros out the data partition. This might be the cause of your problem. It happened to me when I unlocked mine and I got stuck in a bootloop where it kept booting into recovery then shutting off. I fixed the problem by using fastboot to format data. Also, the flashall script didnt work for me. I put all the .img files in the same folder as fastboot then used these commands.
fastboot format data
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
after this I booted into recovery and did a factory reset for good measure and the problem was fixed. This may solve your problem. It may also be possible that you got a bad download. I hope this helps you

Hmm, thanks for the idea, but fastboot wouldn't do "format data", giving me the error: Formatting is not supported for filesystem with type ' '
Googling that makes it not look good. Weird, thing is, it still technically boots up, just the screen is so wonky you can't see where you are or interact with it properly. Not sure what else to try (opening it up and re-seating touchscreen cables?).

Bricked!fastboot works in cmd, no adb, recovery/bootloader menus

Would appreciate your help on the following issue (amoled display):
- phone doesnt boot up, it is stuck to a screen showing htc in the middle and 4 small triangles in the corners; if I unplug the pc cable it goes to a RUU menu
- no access to recovery or bootloader menus (by holding power + vol down/back)
- installing stock RUUs dont work; there is a 110 error saying that the RUU is not complete (tried 5-6 RUUs, both 2.1 and 2.2). there is a progress bar on the phone's screen that is normally green, but turns red when the radio is being written (as per the install wizard on the pc) and there is another triangle showing up at the end of the progress bar
- fastboot oem boot restarts the phone, but then it gets stuck to the white screen having htc in the middle (like when you start up the phone and after this quietly brilliant shows under htc, for me it doesnt go beyond this initial point)
- fastboot reboot-bootloader restarts the phone into the same 4triangles screen with htc in the middle
- adb doesnt work as it doesnt show my device
- any power + vol down/back combination brings the phone to the 4triangles screen
- if I run the stock RUU after fastboot oem boot (white screen with htc in the middle) there is a menu showing up on top of the white screen showing up the progress (1-bootloader, 2-radio_v2, 3-radio, then system, recovery, user data, etc.); bootloader is updated ok but then it gets stuck when updating radio_v2 and doesnt move further from that point)
- after the RUU install fails, I plug out the pc cable and see the RUU menu; depending on the RUU that I try to flash the hboot version changes up and even goes down after, but the firmware (what the RUU installer "sees" on the phone) and radio (seen on the RUU menu) remains the same: 1.21.405.1 and 4.06xx; the date on the RUU menu also changes depending on the RUU that I try to flash
Any suggestions to get my desire unbricked?
Bit of a background to the problem:
- rooted (unlockr) and was having Paul's r3 rom (2.1)
- updated the radio to 5.10xx
- got into silly restarts when using gps and thought to reflash a new rom and went for Paul's r8
- restarts were there also when using the phone normally
- thought to re-do all the rooting, wiping out everything from the phone, etc; so having r8 as the rom (pre-baked version) I started the rooting process with creating again the goldcard, etc etc
- error message at some point saying partition update fail (following the steps from theunlockr as I did the first time when rooting) and then the phone got to this triangles screen with htc in the middle
- strange though that this screen is different than the one when I first rooted when there was just one big triangle in the middle
Thanks a ton guys!
I've seen a few posts about this screen with the 4 triangles, but never seen the result of any potential fixes, or if it was ever actually fixed.
Just an idea, but it was maybe a bad radio flash if you are saying it started playing up after that? Unfortunately a bad radio flash is fairly terminal so I hope that's not your problem.
Good luck with this one and if you get it fixed then post the result here if you don't mind!
Will definitely post the solution when found; so far though nobody has any thoughts around what might be the reason behind this problem and how to get around it. I dropped a few PMs to the people that had this problem in the past and contacted Paul at Modaco, but so far no replies...
You can fix this with an RUU, I've had the same issue when I unplugged too early after flashing, but you are asking for help in the wrong section.
thought that the dev's section is where the best knowledge exists...
about the RUU process, I am trying to flash stock RUU.exe files, but there is a problem when the radio is being written and then I get a 110 error from the RUU install wizard saying that the RUU is incomplete.
for you the RUU install worked smoothly?
If you get a write error during an RUU flash (i.e. while the flashing is taking place, not before) it probably means there's a hardware fault.
Could be hardware, but I find it hard to believe as the phone is new and it is network locked, hence I didnt even use it for real, apart from some wifi and gps activities. Besides, the phone worked very well when I first rooted with Paul's r3 and the whole mess with restarts when using gps started after I upgraded the radio to 5.10xx having a 2.1 OS.
I feel that the problem started when I tried to root the phone being on Paul's r8 2.2 OS (tried to root with a 2.1 system and then it got messed up in the process).
I am not saying that it is not hardware as it is a possibility, but still think that it might be a messy software aspect, as if the radio is messed up from a hardware perspective, then at least the system should boot up and then wifi, gps, gsm and the things that are controlled by the radio shouldnt work...but somehow the OS should start-up.
Basically I dont get a write error, it's just that the error comes up when the radio is being written, hence I think that there is something wrong with the radio set-up that I have now on the phone...
Maybe somebody knows how to flash the system from scratch using only fastboot in cmd (having the right zip or img files properly signed), or maybe just the radio to start with.

Well, I thought that as various solutions to root the phone, to get past different restrictions in the OS, etc. were discussed here, it might be a good thing to develop a way to bring back to life a OS being in this situation like mine...come on...

Thanks anyways man, I looked at that already, but cant get it done as I dont have adb commands available in cmd, only fastboot. Dont worry about waisting my time, I really want that these days
I had the same problem. Passed the device in service center. Changed the motherboard under warranty. It took one month's time.
but to get adb you need to download and install android sdk. look here http://developer.android.com/sdk/index.html system dependands download.
install it here are instructions on how to use if you aren't familiar with.
http://www.londatiga.net/it/how-to-use-android-adb-command-line-tool/
for anything else just use google.
i'm pretty sure that your device is fixable and you can fix it without any service center. cheers and post what ever happens.

I know how to use adb commands...pretty new to android and everything, but lately I roamed a lot through various things about it and learned a lot.
The problem is that adb doesnt list my phone when I run adb devices, it shows only when I run fastboot devices, I am sure you know what I mean...hence I cannot push any files to the phone, etc., at least not using adb in cmd.
That's actually the problem, that I cannot get adb to work, I only have fastboot commands. At least the way I see it now the question is how can I work with the phone to fix it just by having fastboot access in cmd.
I searched quite a lot various forums, etc, but I never came across a solution that will get things going just by having fastboot in cmd (without adb working). Maybe somebody here will come up with some magic trick...

How did you end up having this problem, just like that or after some update, flash, etc?
Thanks!
have a look here mate http://forum.androidcentral.com/htc...9-bricked-my-evo-but-there-away-un-brick.html
same story unfortunately, doesnt apply to my problem. in the link they use a terminal emulator, but I cant use that as it doesnt work...it's basically an alternative to using adb directly in cmd, and this doesnt work for me.
if I am to get adb functionality back, then I'm done with the problem in 5 mins probably...
thanks anyways, keeping the hope alive!
sorry idf i don't underdstand, but if you have fastboot working in your device and sdcard also then you should be able to push files to device via fastboot making as clean installs as possible.so if your device is picked up by command line type fastboot to see command list. i'am a bit comfused. pretty sure you should fix it through fastboot though.

right, I can run 2 things with fastboot in cmd: (name of the files just an example)
1. fastboot update update.zip
here I get that the archive doesnt contain android-info.txt or android-product.txt
2. fastboot flash update.img
here i get signature verify fail
for example, fastboot erase radio says FAILED, remote: not allowed
there are some fastboot commands related to the kernel and some others, but dont know how to make use of them for my problem.
sd card is accesible for sure and it is a goldcard.
I saw some linux/ubuntu methods to simulate adb usage in cmd, but I dont think it will work...will try to find an ubuntu image and mount it under windows, but dont have time now...
anyways, thanks to everybody for the suggestions and interest, maybe we'll crack it some day
You need to use an official RUU zip image - i.e. a PB99IMG.zip. Not an update.zip.

[Q] Evo vibrates 5 times and turns blank with flashing green LED

I was trying to root my phone using unrevoked 3.32 and during the install it, it stop with a back up CID error missing or something like that. i checked to see in hboot if it was rooted with it showing s-off, and it was but recovery still showed the regular triangle red error. So i restarted normally and tried into install terminal emulator on the phone and thats when it first started vibrating 5 times, then go blank with a green led flash. the phone will boot normally usually be able to use it for a min or less then it will repeat with the blank screens. After checking back into hboot it now shows that its unrooted with s-on. Now i also have problems with the usb/sdcard.
Things i have done to get it back to normal:
- hard reset using clear storage.
-Checking in the SD storage menu i could see it wasn't reading the SDCard so i restarted it in bootload and thru fastboot typed: fastboot oem enableqxdm 0.
- flash through bootloader this file : 3.70.651.1_PC36IMG.zip
After flashing it still takes multiple battery resets to finally get it through the first start up menu and then to the regular home screen. Seems to read the SDcard fine but when connecting the usb from wall charger or PC it doesn't recongnize at all.
The phone is 4 days old and seems to be back to stock except it still vibrates and goes blank with green led flash and it wont recognize charging/pc connection. Will i have any problem if i just go back to sprint and say i want a new one its not working right?

That's weird. I'm pretty sure the vibrate 5 times and green blinking led indicates that the phone is in diagnostic mode. I'm not sure how to remedy the situation, I would've suggested a PC36IMG back to stock, but you already tried that. I would try taking the battery out for an hour or more (i've read of people being stuck in diagnostic mode, and leaving the battery out for a good length of time fixed it, i think) then try booting up, and seeing if it works. If not, to answer your question, as long as the bootloader shows S-on, you will have no problems taking it back to Sprint. You need to make sure you have no 'evidence of rooting' on your sd card, just to make sure that the sprint tech doesn't see anything on there. Good luck.
I formatted the sdcard, but it seems to be creating these files QXDM_some numbers.dm is this normal or any indication of rooting the phone.
Sorry to be the bearer of bad news but I had the same issue and eventually gave up after 3 solid days of working on it. You name it, I tried it. Had to get it replaced.
Something about unrevoked and my old 002 phone didn't jive together and the root aborted at an unrecoverable stage. No sd card mount, no adb, not even able to connect via usb, so running an ruu or new pc3600img wasn't an option.
As for the 5 buzzes and shut down after a min or so... Your guess is as good as mine. You can put it in diagnistic mode with the arrow up/power button boot, but thats 3 buzzes not 5.
Wish I could offer some actual help :/ Let us know if you find a fix.
Oh, before I took it back in I did a hard reset so it would reboot before they could get past the setup menus and see the superuser permissions app. Not that they'd care, but just in case.
I have just returned my EVO to sprint for this same problem. He told me it was a common problem. I get my new on today. They could have cared less that it was rooted, he told me it did not matter.

I ended up exchanging mine also. The lady really could have cared less. i wish i would of known cause i spent some time trying to get it back to normal. My sister also ended up exchanging hers because she got the white one and wanted the black one instead.
thanks for any help and replies.
I too had the same problem. It all happened when I was trying to flash cyanogen 7 RC2, I wiped all data, and all seemed fine. I rebooted and it went right to the bootloader and I noticed I was S-ON. Tried to re-root, and run a RUU. I did actually get it to boot to sense, but it froze and then I got the buzzes, and the green lights. I went to sprint since I have insurance. They checked it out and then an hour later, they gave me another one.
My EVO is currently stuck in the same state. I have spent a huge amount of time working on it, and have some information. I'm just dumping as much as I can remember in to this post, so excuse the lack of organization.
Before I go any further - I have not been able to fix the issue!
My phone was about as stock as possible when I took it to the Sprint store. They ordered me a new one and gave the broken one back. I have taken a few more risks now that my new one is on the way.
The initial problem started after flashing MIUI recently. The phone booted normally, but I noticed that the SD card was inaccessible. I would bet that the phone was refusing to charge over USB at this point as well, as that issue goes hand-in-hand with the sdcard problem.
The sdcard and its contents were fine. I later made a backup of the card and lost nothing.
Symptoms, high level info:
Phone immediately vibrates 5 times and begins flashing a green indicator, screen black at power on
Under unknown circumstances, the phone will display the white EVO boot screen before exhibiting the above behavior
Cannot exit this mode unless phone is unplugged and battery is removed
Bootloader can be accessed by holding volume down and power when starting fresh
SD Card is accessible in bootloader - indicates the problem is not purely hardware related
Fastboot can be used to temporarily (1 boot) gain access to sd card
Phone can be flashed with official PC36IMG
Phone can be set into RUU mode and flashed with official RUU
Official update.zip can be flashed from stock recovery
Qualcomm diagnostic tools can be used
Phone will remain in the installed OS for a very short amount of time
Bootloader shows S-ON, 'fastboot oem boot' shows Super CID and CID=111111111 instead of SPCS_001
Because one of my initial ideas was to flash a stock PC36IMG from the bootloader, I lost access to a custom recovery very early in the process. Other users may have better luck if they do not immediately flash a stock recovery.
Flashing PC36IMG is accomplished as usual. Vol- + Power.
To temporarily enable the sd card, disable Qualcomm Download mode:
Boot into bootloader
Wait for it to scan the SD Card
Select Fastboot (Power to select)
Plug into computer
Open a command prompt and ensure you have the fastboot executable
Command: fastboot oem enableqxdm 0
Exit fastboot
Select Clear Storage and select No to reboot OR
Select Recovery
The phone will boot into the OS. Under unknown circumstances, the phone will reboot. The amount of time can vary quite a bit. Enabling Airplane mode does not help. Using diagnostic tools to put the phone in Offline mode does not help.
If you would like to use Qualcomm diagnostic tools, the phone will have to be in diagnostic mode, rather than Download mode. The above steps will get you most of the way there, with the added annoyance that the phone will not enter proper diagnostic mode if left plugged in the entire time.
To ensure diagnostic mode correctly enables (or rather, that download mode disables):
Perform the fastboot command to disable qxdm
Unplug the phone
Navigate back to the bootloader, select Clear Storage
Select No (Vol-) to reboot
The white EVO boot screen will display
The screen will go black before the Sprint/4G animation plays
Plug the phone as soon as the white screen disappears, before the Sprint/4G animation
The phone will display in QPST Configuration without saying *Download* everywhere. The phone number will be incorrect, but that value is actually stored as a Directory ID in the NAM. In other words, it's okay.
The QPST Service Programming tool looked like a good place to start. If you would like to look at the configuration options for the EVO, you can start an offline connection using the profile "FFA/SURF QSD8650 Rev 2.0".
Note that the phone will always reboot after writing any values to the phone. This means you will have to pull the battery, unplug it, boot into fastboot, disable qxdm, boot into the OS each time.
You will need your MSL code for many of these applications. You can get it by calling Sprint and asking. They will not provide the code through email.
I can confirm that at least some changes in the Service Programming app will stick. I changed the banner, under the Display tab, to "Brick" (from Sprint), and it showed up in the Notification dropdown.
The NV util can read the values from the phone correctly.
QXDM can issue command to the phone.
ADB will not work. This limits the ability of tools like unrEVOked to do whatever they do. Getting ADB to work could be useful. Note that I did re-enable Debugging in the Setting->Applications menu to no avail. I believe this is a general side effect of this problem and perhaps a key symptom.
The bottom line is that I have run out of ideas. I have not found a setting in any of the QPST or QXDM tools that indicate this mode can be turned off. I have a hard time believing that there is some permanent switch in the Qualcomm SOC that says "always boot into this mode forever", but who knows.
Any suggestions would be great.
To summarize, I have installed a stock PC36IMG, update.zip, RUU. I have access to almost any setting in the phone, but cannot write to NV because it's in the S-ON state, which limits certain fastboot wipe options and the ability to push new images to system partitions from fastboot. I can, in theory, use the QPST Download software to move images if I can find one that might work.
When is the last time you tried running a 3.70 PC36IMG RUU?
I ran the 3.70 RUU literally minutes ago.

Apparently still not taking?
That's the thing - it *is* taking. Whatever is triggering this mode is not being reset by the RUU (or any other full clear/flash technique).
I have a dump of the NV memory, but I want to run through it with a hex editor to make sure it doesn't have anything that would identify my Sprint account or identity before posting it.

Ah I see, and good precaution.
My ESN is in the qcn file, and I assume my MEID is as well. I will try to zero them out if I can find them all.
If my phone's ESN is 12345678, then it is in the qcn file as 78 56 34 12.
Does anyone else happen to have a known good QCN? Maybe I can compare them side by side to locate the differences. I suspect that there will be a lot of them, but I can eliminate most of them pretty easily.
While I work on the file (and debate whether or not it's safe to post), here is some information from the NV dump:

Without bothering to specify all the set bits (although there are some interesting ones like "Bit 306: F_UI_GOOFY_MENU_BIT"), maybe someone can confirm that 108 or 432 is close to correct.
I loaded up a nv.img from a nandroid backup I took the day this problem happened (before flashing a ROM). I suspected that the nv.img and the qcn I just pulled should both represent the same general memory in the phone.
The image is...definitely an image. Exactly 640kb, tons of empty space and apparent padding. Much different in overall layout than the QCN, and no trace of my ESN. However, I was able to locate the GPS URLs in both files. While not even close to the same offset in the file, that small section of similarity indicates that the same memory was probably accessed.
Unfortunately I know of no way to push the nv.img to the phone in its current state. If I were able to get the nandroid backup's nv.img onto the phone I could at least eliminate the entire NV memory as a variable. If it fixes it, then awesome, and if it doesn't, then I can ignore the file entirely.
Here is the QCN file with my ESN removed. There may be other private information in the file, but at this point, Sprint is ordering me a new phone, and gave me this one back, so I don't know if they can really do anything about this.

My enthusiasm toward poking around this file is dropping off pretty quickly since I no longer believe this is where the problem lies.
I had the same thing happen to my EVO last week. Pretty much the exact same symptoms as you. I was able to get the RUU to run, and return my phone back to stock thinking this would fix the problem. I can boot into Sense, but the phone will shut off and do the 5 vibrate thing within a couple of minutes.
I took it into the Sprint store, and the rep told me there is nothing they would do and they would not replace my phone. He assumed it had been rooted (which it had, but I returned it 100% to stock before taking it in), but I have also read of this same thing happening on unrooted phones. I plan on calling Sprint and/or HTC directly to try and get the phone replaced.
From what I've read, it kind of sounds like this is a hardware failure. Possibly something in the internal memory or RAM. Of course, this is just mostly a guess I have. It seems this happens to unrooted phones, but is more common on rooted phones, possibly because of all the flashing we do.
Like I said, it's just a guess of mine, but it kind of makes sense. I wish I could be more help, and I'll definitely be following this thread because this seems to be a fairly common problem with EVOs and Incredibles that nobody has seemed to figure out yet.
hello,
the problem is heat.try to use your evo on the AC vent in your car with ac on you will not get reboot or eny shut down than try to use with out ac...
whenever internal temp goes more than 38C the evo goes off 5 vib. and flashig..
i spent long time testing this so i almost 100% sure that heat is the problem with my evo...
i dont know if there is a way to change the seting on shut down due to heat but it mey be...

I was never able to fix mine, but before getting it exchanged i let it sit all night with the battery out and would have the same results. So i know mine wasn't overheating.

I was trying to root my phone using unrevoked 3.32 and during the install it, it stop with a back up CID error missing or something like that. i checked to see in hboot if it was rooted with it showing s-off, and it was but recovery still showed the regular triangle red error. So i restarted normally and tried into install terminal emulator on the phone and thats when it first started vibrating 5 times, then go blank with a green led flash. the phone will boot normally usually be able to use it for a min or less then it will repeat with the blank screens. After checking back into hboot it now shows that its unrooted with s-on. Now i also have problems with the usb/sdcard.
Things i have done to get it back to normal:
- hard reset using clear storage.
-Checking in the SD storage menu i could see it wasn't reading the SDCard so i restarted it in bootload and thru fastboot typed: fastboot oem enableqxdm 0.
- flash through bootloader this file : 3.70.651.1_PC36IMG.zip
After flashing it still takes multiple battery resets to finally get it through the first start up menu and then to the regular home screen. Seems to read the SDcard fine but when connecting the usb from wall charger or PC it doesn't recongnize at all.
The phone is 4 days old and seems to be back to stock except it still vibrates and goes blank with green led flash and it wont recognize charging/pc connection. Will i have any problem if i just go back to sprint and say i want a new one its not working right?

It's bricked. Happened to me when I tried to fix a problem with my phone not mounting the microSD card to any computer (got error message back on a Windows computer saying that the device wasn't recognized). You could probably try to flash the PC36IMG.zip file again from the bootloader, this time without all the addenda at the beginning (if you did that already, the nevermind).
My guess: pray that Sprint doesn't see any evidence of root. If you RUUed back already, they may not see it. You're probably in better position than I am, since the brick happened before I could RUU back with a PC36IMG file (and thus Sprint could see the root. At least Asurion doesn't seem to care about root, as long as I say nothing about it).

Internal SDcard Busted, Can't Format or Write (Forever Locked as Read-only)

HI,
I used to be more active in this forum, but honestly nowadays I can't found any reason to since everything has been smooth sailing for me without any problems—until this day, at least. Somehow I got my internal sdcard busted, it was pretty spontaneous, all I can recall is suddenly the system starts to reboot itself. Nothing much, I thought to myself, problem is the system keeps rebooting, it doesn't even last a minute. Naturally when faced with this problem one would do the usual procedure, namely completely format the thing to stock the rule out any possibility on the user side of things, but then this is the part when it starts to get interesting...
The thing refused to be formatted, seriously, it baffles me at first but it does
Things I've tried:
Fastboot, it hangs at writing system, whether I was doing it line per line manually or via the flash_all.sh script, I haven't tried the toolkit but I think it's safe to assume that It'll do the same thing. Even if it does go on (which it did, once) it doesn't do any sort of changes whatsoever to the system.
ADB, nope, not this one either. And since the system reboots faster before I can do anything worthwhile it's pretty much out of the question.
Recovery, multiple times I've tried nuking everything via CWM, nada. I've tried TWRP too, I have to boot it from fastboot since it apparently doesn't allow me to flash a new recovery either, it reverts back to CWM every time. Also tried to flash a different ROM (CM), that didn't work, it spits out an error message regarding some failure in changing metadata, thought it was a corrupted file or something, so I re-downloaded it, that doesn't work. Still convinced that it's corrupted I tried 4 different version of it without any luck. Even the one I had successfully flashed before. Interestingly enough, flashing the exact same ROM I'm currently using (ShinyROM) works, not that it seems to do anything.
Built-in data format from settings, now this doesn't work because I assume that it needs the stock recovery to work, which I couldn't flash because it wouldn't let me—in a sense that it flashes just fine on the command line—fastboot doesn't show up any error or anything—but it defaults back to CWM as soon as I reboot it.
Manually via terminal emulator/file manager, still nothing, curiously enough, Terminal Emulator indicates that the whole system is read-only (I tried making a file with it, it shows that exact message).
Grit my teeth, clench my fist and screams out every curse word that I know of, this somewhat reduced my stress levels, but ultimately yields nothing.
Which led to be believe that either my phone was either a) Haunted or b) Has a serious hardware problem, I'm leaning on the latter. A few quick lookup with my limited amount of Google-fu and I've found several threads that described the exact same issue:
http://forums.androidcentral.com/go...-factory-settings-no-matter-method-i-try.html
http://forums.androidcentral.com/go...eset-nexus-7-2102-using-multiple-methods.html
Both of which hints at it being a hardware problem. Which was my biggest fear since I can't really revert the phone back to stock now can I? Locking the bootloader doesn't seem to work either (the 'fastboot oem lock' command works just fine but just like every single thing I've tried, reverts back to my previous setup as soon as I did a reboot), plus this means I have to send it back with my private data still on it, and I can't say I trust Samsung, Google (or anyone really) with my private data. Not to mention some of the stories I've heard/read about Samsung and their policy regarding rooted devices (much less ones with an unlocked bootloader).
In case it helps, here's a few more details:
What state the device is currently in:
It boots up just fine, but nor for long, apps starts to hang and ends up with a cold reboot (sorry if it's not the right jargon, but it starts right from the Google screen).
Everything that doesn't require you to access the filesystem works fine.
Apps doesn't seem to be able to write anything to the filesystem, I tried backing it up with Titanium Backup, much to my surprise the backup files weren't made (although TiBu seems to indicate that they were).
What the device is running:
Variant: Maguro 16GB
ROM: ShinyROM 4.4.2
Kernel: franco.Kernel r395
Baseband: XXLJ1
Bootloader: PRIMED04
Also I don't know if this will affect things but for the record I'm running the latest Ubuntu and Debian.
So this post is pretty much a shot in the dark, since I think I know what I'm dealing with already; if anyone had this problem before in the past, or has it now and somehow managed to fixed it, please do tell. Or if anyone has any experiences RMA-ing your device with a condition like this I'd love to know.
Yep your EMMC is fried. Sorry man.. But you can go to warranty. They *should* accept it since it is a developers phone but they could make a lot of hassle about it being rooted..

Soft Bricked - Unable to Sideload OTA

Hi all,
My Nexus 5x (16gb - all stock.) went and soft bricked today. Not sure why - just seemed to start wanting to constantly restart - never making it past the white google text part of the boot process. Not sure if it's an update or hardware. No trauma or dropping of the phone - which makes me think s/w rather than h/w.
I have attempted to install a rescue OTA update (instructions I followed are from technobill - don't have enough posts to add a link). However, when running "adb sideload <file>" I get a "failed to read command" error. Have tired multiple cables/ports however to no avail.
(Recovery screen shows the following build details: 7.0/NBD90W/3239497)
Any ideas?
Thanks.

Did your phone just reboot in the middle of doing something innocuous then start bootlooping? Were/Are you on total stock with bootloader locked? If both yes, it is probably hardware issue you are encountering.
Regarding sideloading, did you place your Android recovery in sideload mode?
Did you verify adb can "see" your device using "adb devices"?

Well luckily I made this post today.
The more this goes on, the more I believe it to be hardware ...
@sfhub - reasonably innocuous. Had just opened one or 2 apps that morning. Not sure what had updated overnight app/os wise. Not anything interesting as far as I can tell. Once I managed to get it into recovery "adb devices" was returning the phone.
@bardhi92 - I saw that once I got in. However, I couldn't get it to see my phone.
Updated things I have tried and why I've all but thrown in the towel:
After the OTA rescue sideload failed I started trying a few different things. It stopped taking me into recovery mode more frequently, at least it seemed that way - it would just keep bootlooping. My main issue is that I has a locked bootloader, which stopped me whacking TWRP on and loading on a custom rom - just to see if that worked.
I thought it might let me sideload on a factory default img file. Turns out nope.
However I used NRT to "Flash Stock + Unroot" (with "Soft Brick/Bootloop" checked) which for some reason, then allowed me to get back into recovery mode. I had also removed the sim card/tray at this point. May have been either or neither of those that allowed me to get into recovery mode. Can't say for certain.
I cleared /cache and /data and then attempted the OTA rescue update again. This time it failed at 45% (according to my cmd prmpt) with the error: "* failed to read command: No error". I'm not sure text was on the phone at the time. But it did manage to boot into Android. I quickly stepped through the various intro steps (putting in the sim, adding my mail google account details).
I went to get a beer. Only to find it boot looping again.
Not to be deterred, I vowed to try again. Same steps as before (remove sim, nrt voodoo). This time however the OTA rescue worked and fully completed. I went through the intro steps again. This time I quickly turned on dev options, enabled usb debugging and sorted out the OEM bootloader. I thought this would be smart, just in case it hapened again. Once I chose to unlock ("fastboot reboot", selected yes), it decided to start boot looping again.
The main annoyance is: I don't think I have any proof of purchase, even though it's in warranty. That, and I now live in Dubai - so shipping back to the UK where I brought it is going to be killer. But I think it's the path of least resistance at the moment.

So, you flashed the .TOT file, sideloaded the given OTA within the stock recovery bootloader that comes with the .TOT file, and cleared cache/factory reset?
Please condense it. If you managed to start up the phone, that's a huge success for people who have not been able to yet.

In short:
OTA rescue failed during adb sideload,
Tried bullhead-nbd90w-factory-d2f11c5f.zip & removed sim tray - seemed to allow access to recovery mode,
OTA rescue claims to have failed at 47% during adb sideload- still booted into android. However briefly. Went back to bootloop,
Tried bullhead-nbd90w-factory-d2f11c5f.zip & removed sim tray - seemed to allow access to recovery mode,
OTA rescue completed via adb sideload,
Turned on dev options (usb debug, oem unlock),
Booted to fastboot - unlocked bootloader. Now back to bootlooping
@bardhi92 - I could not get the LG utility to detect my phone. Will attempt again tomorrow.

IMO you shouldn't flash the TOT file. If you end up bootlooping again, your phone will be stuck in bootloader locked mode with no ability to unlock it.
If you were able to get your phone to boot into android once, there is really nothing the TOT file will do for you that you can't do from TWRP or bootloader, whereas once it locks your bootloader, there are problems you can no longer fix like EFS corruption (which likely isn't your problem).
In the end, you probably do have eMMC that is slowly starting to fail. There is usually error correction on the eMMC that can lock out bad blocks but if it gets to serious, it'll fail. This is why reflashing stuff over and over sometimes works.

Help -- phone won't boot and I need to get photos off

My daughter has been using this phone, but never backed her photos up. Now it won't boot and she is worried they are lost forever. I've been trying to help, but only seem to make things worse.
1. She never enabled USB debugging, or rooted it
2. She could not tell me whether she had allowed the OTA upgrades.
3. It got into a reboot loop a few days ago. It would start to boot, then say it was optimising a random number of apps (anything between 90 and 158) and then start over. Wileyfox tech support told me that this was due to an incompatibility between Cyanogen and the latest Facebook Update.
4. They sent me a link to the FOTA files with instructions how to progressively upgrade to Android 7 (TOS111B)
5. They couldn't tell me how to determine whether it was running CM12 or CM13 (I now realise that I could have looked at the log files in the recovery partition)
6. I therefore assumed that it was running CM12. I used their instructions to go into recovery and manually update from SD card to ZNH0EAS2NH from there to ZNH2KAS7EB and then to TOS111B
7. Fatally I did not reboot between updates. At the end I had the Wileyfox splash screen black on white, and then got an animation with it red on white. It then got stuck.
8. I then tried using fastboot to go back to the original version of the OS so I could start over. I found the fastboot image and I flashed the boot and system partitions.
9. Now on boot it either gets stuck on the black on white boot screen, or it displays it for a second and then turns off.
Can anyone help me? - I think my daughter will have a nervous breakdown if I don't find a way of recovering her photos. Recovering the photos is more important than unbricking the phone.

Since posting this I have had a partial success. A more complete set of fastboot flashing using the TOS111B fastboot images has got me to a phone that boots. Many of the apps work. However...
a) I get an "unfortunately the process com.android.phone has stopped" appearing almost as fast as I can close the app making it very difficult to get anything off the phone. However, I did manage to set up a google sync to upload the photos.
b) my daughter now tells me that her SMS's are vital.... and the messaging app says " getting message" then closes down
c) I cannot enable developer setting to enable usb debug mode. I can get into the phone status page under settings. Repeated tapping on the android version brings up the nougat splash screen, but the 7 taps (or 700 for that matter) on build number does nothing whatsoever.
Does anyone have any ideas how to recover to a fully working system without doing a factory reset?
I suspect that the sms database would have gone when the cache was cleared. Can anyone confirm that to be the case before I spend any more time trying to recover them?
Hi Jerry ,
Exactly the same problem here. Could you tell me where you've found the TOS111B fastboot images?
Thx!
Have you tried booting into safe mode?
I think you do that by pressing and holding the volume down down button during reboot.
If you can manage that you may be able to dissable the apps that are causing the crash.
