[Q] Nexus 7 (2013) fails OTA update to 5.01 with Android Error - Nexus 7 (2013) Q&A

My unrooted, stock Nexus 7 was on 4.4. I received an OTA notification about 5.0.1 so accepted the upgrade. After the reboot and seeing the Android with the open stomach, it fails with Error against the Android. All I can do is long power off/volume up to power off and then power on again. It then reverts back to 4.4.
After about an hour I received another 5.0.1 update, went the same process and received the same error.
Does anybody know what that could be? I guess I could factory reset the device there is nothing on the tablet that hasn't been saved in my Google account anyway.
Thanks

Wanted to say I experienced the same thing earlier today, except I didn't get an immediate second chance at the OTA. I have the wifi-only version of the N7 2013, and it is also not rooted.
Browsed around the net and various places to see if others had this issue, but no luck. Not really sure what the problem is unless the download got messed up somehow?

Same issue here. Download the update. It shows verified. Reboots, starts to flash and then the android error
Reboot and it is still 5.0

Happy to report that when I got another crack at the ota the update went fine. Still confused as to what could've caused the problem though.

Well it killed my N7 it seems. Got the error message then shut itself down. Now it won't boot up no matter what I do. Any ideas?

My update just stays in the notification area. After the failure I just power the tablet off with long press of the power button and volume up.

I am stock, rooted and unlocked. I used the WUGS toolkit to flash the stock recovery assuming that this is all that was necessary for the OTA to be recognized and accepted. After flashing back to stock recovery, I rebooted the device and told the OTA to update. It starts going through the process and dies with "Error!" and reboots back into 5.0. I tried using the WUGS toolkit to ADB sideload, but I have not been able to get it to work. At some point, it actually got into the Stock Recovery, but ADB wasn't able to contact the device (that only happened once). Every other time, it goes through the script and shows the Android on it's back with the exclamation mark, and below it says "no command."
The device works, but it's frustrating. I wish there was just a way to fastboot the OTA, or just do it via TWRP.
I'm anxious to hear how others work through this, as it appears that I'm not the only one.

Tried sideloading the factory image?
Sent from my Nexus 5 using XDA Free mobile app

Since my N7 is a secondary device (my main device is a N5 which received the Lollipop upgrade fine), I might just leave it on KitKat rather than muck around with sideloading Lollipop. KitKat works fine for me at the moment. But it's really annoying that a stock N7 cannot get an OTA upgrade and goes into an Android error state.

I was on 5.0 rooted with TWRP and got the same error trying to take the OTA. So I downloaded the rooted rom found here http://forum.xda-developers.com/nex.../rom-factory-stock-rooted-rom-lrx22c-t2960745 , used Wugfresh's NRT 1.9.9 to update the bootloader, and then dirty flashed the 5.0.1 rom with TWRP. Painless and fast with no loss of data or anything.

Same problem! I managed to workaround the issue by using fastboot replacing system.img boot.img recovery.img with stock ones!

Are you suggesting that I blow away what's installed and just update by doing a fresh install? would prefer to not do that.
I did download razor-lrx21p-factory-ba55c6ab.tgz (the 5.0 factory image) and extract the recovery.img for it, and fastboot flashed it, and the no matter what I end up in the Recovery bootloop with the android on it's back and exlamation point and "No command."

If I am not wrong, there is a way of flashing the factory image without wipe by modifying one of the scripts, never did it though myself.

Turns out I was using the wrong key sequence for Recovery to get past that screen. Holding down Vol Up + Power for 3 seconds, then just pressing Power gets you to the right place. Am still having issues with OTA, as the system believes something was altered (install-recovery.sh). Others are saying that the way to do this is as described here: http://forum.xda-developers.com/showpost.php?p=57271130&postcount=423

jep, that's what I was saying earlier: factory image. For the 5.0.1 update you only need system.img and boot.img, at least that way it worked for me and my N7 2013 is running fine so far.

I dont get 5.0 on my nexus 7 2013, wifi, 32 Gb(flo, ktu84p)
I had stock rooted Rom, u Used tweaks like softkeiz etc. then I unrooted, locked boot loader and flashed stock recovery. Android lollypop rollout was about 2 months ago, but I don't get 5.0 ota. Now I'm running 4.4.4 stock rom , locked boot loader and I unrooted it with super user unroot option. Can somebody help me why I don't get my ota?? Thanks ^^
I know that's wrong thread, I didn't find thread for my question .

I just got my update!!!!!

Oh man! It's crasy, I was waiting so long, and exactly on this day when I write to thread I get my update!

EDIT: Never mind. I tried to do it via sideload, and it complained that the /System was too full. I rebooted, compared it to another Nexus 7, and the size was the same and free space was the same (and the other one updated fine). for the heck of it, I tried sideloading again, this time I formatted the cache first (no reason, just a thought) and that time it sideloaded correctly. So I'm up to date now... Weird.
I have the same issue. did a factory image install to 5.0. Now I get the update notification for 5.0.1 (as expected).
When I try to install it, it reboots, then I get "error" - have tried 3 times now. A reboot gets me back in the tablet, but am still at 5.0. This is my kid's tablet, so I have no need to root it or install a new rom, just want the dumb update to work correctly...

That is indeed strange...If you are pure stock it should work I guess? You could still try to sideload the 5.0.1 as well (did the same as I did not want to wait for OTA). You can do it without full wipe, just wipe cache in the process. (You need only to flash system and boot.img, wipe cache, reboot). Nevertheless let me know if you get the "error" solved, would be interested to know.

I was skeptical but this worked when I was having a similar problem to the OP Thanks. I have no idea how 5.0.1 is different though.

[Q] Loads of Problems (rooted, unrooted, firemwares, flash, stuck on logo screen)

I'm having one hell of a time with this tablet. This is pushing a month and I'm still not satisfied with my tablet.
Tonight I finally tracked down what I had hoped was a stock firmware for my tablet. Halfway through the download it timed out and when I went to download it again, the same thing happened.
So I tried to take my tablet that isn't "properly rooted" anymore and use Odin 9, instead of Odin 10, and place kitkat on my device rather than be stuck with Lollipop 5.0.2. All of this because The Sims Freeplay app isn't working and I can't find another soul on the face of the earth who can give me an answer to why this is happening.
Now I'm stuck on the samsung logo. I managed to get it back in download mode and that's where I flashed Lollipop 5.0.2 through Odin 10. I figured that would solve my problem. It didn't, but at least I got TWRP back on my device.
I never recovered anything that came with my tablet. I did not think I'd ever go back to unroot nor did I know how to back it up in the first place. So there's nothing in my recovery I can boot from. So what I did was I came back here and I downloaded the recovery for TWRP. I flashed it from my SD card, it told me it was successful... now what? I've rebooted and my device still loads to the samsung logo...and just stays there. The little confetti animation happens behind the logo, but that's it. It doesn't turn off. It doesn't reset itself.
CAN SOMEONE PLEASE TELL ME WHAT I'M DOING WRONG?!
I've already voided the warranty on this device and I regret almost daily that I decided to root in the first place. I say this only because I think rooted devices are top-notch, but I haven't been having very much luck with them. It took me a week to root. When I finally rooted then my favorite app game stopped working. Then I figured I could flash the stock firmware easily (but it seems like every place I go to find kitkat or even stock lollipop I can't find or I do, but files are corrupt or sites are full of ads).
I can't use my device at all now except click around in TWRP which isn't doing me any good.
I just want my tablet back. I spent 500 dollars on this thing and I haven't had time to even enjoy it. It's only two months old.
Please. Again. Someone HELP me. I want to figure this out and I don't want to accept that I bricked my device because I've watched plenty of videos on youtube and people are stuck with a phone that's resetting and all they do is fix it right there in front of my eyes.
Why can't I fix this? What is it that I'm not doing properly?

I just skimmed through all this reading, so I may have missed a few things. The thing I didn't see if factory resetting. You need to factory reset in twrp. Just go to wipe and factory reset. Now reboot and wait at least 20 minutes as it does take quite a while to boot.
If doesnt do, transfer a custom stock based ROM for your device (any KK ROM should do) to your SD card. Factory reset in twrp and flash ROM. Now reboot and wait.
Typically, flashing with Odin takes 20 minutes to boot up for the first time. Just be sure you factory reset.

Sometimes. Try and wait 10 more minutes.
If it doesn't boot, I think you may have to flash a custom stock based ROM and flash it from your SD card in twrp.

Custom Stock Based Rom? Does that mean I'll push myself further away from a stock firmware? Also... where do I find one and are there instructions for it? I thought roms were firmwares up until like 4 hours ago and I've been reading of roots for a little over a month now.
I see you've got the same tablet. By any chance are you running 5.0.2 lollipop and do you happen to know having a rooted device is the reason why The Sims Freeplay won't get past it's splash screen or if it's the app itself and it's newest update that made it wiggy?
I'll flash whatever at this point, but my main reasons for continuing to mess with my tablet was because of not being able to play the sims on there. Every other game I play works.

The only thing I can suggest is download this to your SD card and flash it in twrp. http://forum.xda-developers.com/showthread.php?p=56345482
The Sims may not work because its uncomptiple with lollipop.
Simply, hit wipe in twrp, hit advanced wipe, and tick system, dalivk and cache. Then go back and install the Cm11 zip and reboot. Hopefully it gets you booting

I'd actually flash this as its more like stock just debloated.
http://forum.xda-developers.com/galaxy-tab-s/development/prerooted-stock-touchwiz-rom-t2973107
You need to wipe system, dalvik, cache and data then Install via twrp.
Wait at least 10 to 15 mins after install for initial boot up.
For future reference whenever you go back to kitkat from lollipop you need to wipe the data and cache partition first.
By the way some apps and games do not work on rooted devices for security reasons.

I understand that. That is why I clicked unroot in supersu and tried the game app, but it still wouldn't work. On my galaxy note 3 I run 5.0 lollipop and my game works fine. My phone isn't rooted and I never decided to root it and then unroot it.
Is an app smart enough to know when a device has been rooted and if are those that hack their actual game on rooted devices uses cloak or xposed or both to by pass their root?
I rather be unrooted for the sake of the game, but how does one find the stock firmware? Or is it not possible at this point?
Sorry for any confusion.

Okay. I installed or flashed ironrom to my tablet from twrp. i followed the directions it told me and I decided to pick the regular rom above the custom one that was close to stock. Then it told me that it was going to reboot; which it did. When it came back it got stuck on the same samsung loading screen so I powered it off, went back into TWRP (because powering off now isn't possible, more like restart) and I went to "Reboot " and then I clicked "power off".
I guess I'll be waiting for 10 to 15 minutes.
I Pray I did this correctly.

Why did you reboot back into twrp? You should have just let it do its thing after it rebooted.
So for any others that may happen upon this thread.
What was your solution?

I did because I thought it had to be shut down before I powered it on and waited. I realized afterwards that you probably meant to just let it sit for 10 to 15 minutes.

cant reboot after failed encryption
I was trying to encrypt my galaxy tab s, which is rooted and has lollipop 5.0. Afrer reading encryption failed. I tried to reboot in recovery via twrp. My device doesn't reboot, it just acts like its going thru the motions. Only to return to twrp recovery menu. How do I reboot the system clearing the failed encryptions. I am a noob and any suggestions would be much appreciated.
You will have to go into recovery and wipe the data and cache partition then reboot.
It may take a while to boot up after that.
Well I thought my solution was using IronRom... but i'm not too sure now.
I just got back from work and I went to turn on my tablet and it took me to the same loading screen and then after about 5 minutes it tells me that the system can't respond. It asks me to click "ok" or "wait" ... clicking either just turns my tablet off.
Now the screen has dimmed. It's turning on when it wants and sometimes it'll show me the time in the upper right hand corner, but it won't let me do anything because it's a black screen.
What does all of this mean?
I just noticed if I click the "power button" it just flashes my tablet desktop then goes back to black, but it shows me the battery percentage and the time in the upper right hand corner...

Unable to Install OTAs After Returning To Stock

Hello XDA Members,
Whelp... I've tried everything. I followed this how to on returning to stock, I've tried THIS method of returning to stock, I've tried them all and I am fairly certain everything was done correctly. I have reflashed the stock bootloader, and flashed the stock ROM image from google themselves and I have relocked the bootloader and am still having this problem.
I can flash stock images supplied from Google with no issue, but the big issue here seems to be when I try to install any OTA update, specifically (in this instance) the Marshmellow update.
I always hit "Reboot and Install". It always shuts off and gives me the little android robot with his antennas wiggling, and it shows a progress bar while saying "Installing system update..." and about 1/4 into doing so, everything stops, the Android robot is now laying down with his little chest open, and a big red exclamation icon is popping out, and under him it just says "Error!"
And that's it. The tablet will just stall there for about a minute and then reboot itself. The OTA will re-download itself and I'm back to square one.
I have no idea why it's doing this, or if I did something wrong in the unrooting process, or how to make this stop.
Please help T_T

You say you can flash stock images OK - so why not just flash the latest Marshmallow stock image? Why mess around with trying to install updates? Why did you re-lock the bootloader? Follow directions here, then flash the newest image under "razor" for Nexus 7 [2013] (Wi-Fi)"

You say you can flash stock images OK - so why not just flash the latest Marshmallow stock image? Why mess around with trying to install updates? Why did you re-lock the bootloader? Follow directions here, then flash the newest image under "razor" for Nexus 7 [2013] (Wi-Fi)"

I don't want to flash it manually, and I want it to be able to install OTAs normally because I'm trying to sell it to a friend and don't want them to constantly to be seeing a "Update Available" notification that wont go away.
Nothing? No ideas? ......Anyone?

I tried this using ADB sideload, got "signature error"??

Nexus 7 dead after original update MM 6.01?

Yesterday my nexus became the update for MM6.01.
After an half hour of updating the device was booting again I get the Android robot wit an open belly and a missind something message?
I tired to reboot with volume and power phused but nothing is happening?
Now I only have a black screen?
How can I bring it back to life?
Thanks and greetings,
Erik.
Use for example nexus root toolkit.
Make wipe in recovery, then flash stock latest 6.0.1.
Thankd for the help,
I will try it!
im on stock 6.0 and my tablet doesn't boot up after the 6.0.1 update install.
its stuck in infinite boot loop.
tired clearing the cache partition from recovery but in vain!
any help?
MMhh can get it to work?
Tried to restore/upgrade/downgrade and choose for oft bricked/bootloop and then select the original 6.01 image but all I am getting is not connected bacuse I am not getting it in the download mode?
It worked!!
After more then ten minutes trying to get in the the bootloader mode it was easy to use the program and the original image from https://developers.google.com/android/nexus/images#razor it worked fine!
Thanks for the help!
Yes, that is the way I got the OTA on with NRT and it worked. However, if you try to root the device afterwards it fails at the installing SuperSU and BusyBox installs. I can never find the files even though they are on the device.

Stuck in Boot loop after weeks of normal usage

Hi.
I have a problem with my D855. My phone is rooted and runs the fulmics ROM. Everything was working fine, , on Fulmics 5.3, except than one day, I was using my phone normally and then it crashed. I saw the phone rebooting, but for some reason it got stuck. The phone tried to boot unsuccessfully until the "firmware update" went through, after what it reboots again (unsuccessfully) and so on.
At that time, I was able to access twrp, do some backup, and flash properly with a downgraded version of fulmics (from 5.3 to 4.1).
It was able to boot again and use my phone like before. Yet, after one month of usage, the same problem happened on version 4.1. The phone crashed and now cannot boot.
Any idea of where it is coming from? Should I go back to stock? Should I contact customer service?
What did you do before the phone crashes ?
I think you probably should flash the stock ROM and wait for an other crash... or not.

I haven't done anything special. I think that the first time I was playing on candy crush. The second time I was just looking at pictures in my gallery.
I was using the ROM without any tweaks or extra modules such as Xposed. Just regular use.
Update on my situation: I switched back to stock ROM and it seems to work OK for now (it has been 4 days). So I will wait and see if new problems happen. By the way, it was extremely difficult for me to get back to Stock directly from fulmics ROM. I tried several methods that I have found on xda based on LGUP or LG Flash tool without success. For some reason I was not able to connect the phone to my PC in download mode.
The only way that I found was to use a nandroid backup that I did just after rooting the phone and that was based on stock ROM.

You can also use the Stock rom flashable from twrp. So you can wipe the system partition and get a "better situation" than a nandroid backup that should be with an old version.
Or use this that has also root and other improvements.

Same problem here. Normal usage suddenly started to reboot and now it's stuck in boot loop
Coming from Fulmics too - stopped working one fine day.
Now, continues to boot-loop at the initial LG screen. Trying to get into the recovery shows me the the 'Factory Reset' screen, but beyond that leads to boot-loops again. Even the Download mode loops!
I'm at my wits end without a solution in sight.

Thank you for this advice. I was able to update my stock ROM after the Nandroid backup through LGUP, but your method would have been faster.
But anyway, I am waiting to see if I am stuck with bootloops again, using non-root stock version, so I can send it to customer service if this happen again.

Are you using Fulmics ROM as well? Can you have access to TWRP? I was able to connect to a PC in the recovery mode and to transfer files before flashing, in case you need some basic backup...

Silly question, but are you sure that you selected "Yes" when the screen asks you about factory reset? you have to press "volume down" and the "power button", since the default answer is no.

Yes, of course I was able to access TWRP successfully earlier.
Curiously enough, the phone boot-loops in regular startup, Download mode and trying to get to recovery. However, it doesn't restart itself and fall into a loop, while on the Factory Reset menu. Am I correct in assuming that the battery could not be the root cause of the overall problem? Because if it was, it would likely loop even on this Factory Reset menu as well as far as I understand.
Unfortunately, the phone restarts as soon as it lands in the Download mode so I cannot even restore to stock.
EDIT: Okay, weirdly enough it just booted and reached the homescreen before restarting again. What I did was let it charge to a 100% and tried booting while plugged in. Could it be the battery after all? Though this exact set of steps hasn't been helpful before.

[REQ] Help: bootloop after 7.1.1 beta OTA and cannot enter recovery mode

I've been watching several threads for the last few days, and have not seen this exact issue. I would greatly appreciate some help.
Device:
- Nexus 5X LGH790 32GB
- Stock bootloader / fastboot
- Never unlocked / rooted / etc.
The only advanced thing I've done is join the beta program a few months ago to get 7.0 early. Got that without any issue.
Issue:
I received the 7.1.1 OTA on the day it came out. Installed with no problems. The next day, the phone just froze in the middle of regular use. After about 15 seconds, it started boot looping to the Google splash screen. I can hold volume-down to enter fastboot, but when I select recovery mode, it just starts looping again. Pretty much all I could do was power it off. I did find out by accident that if I left it looping for long enough, sometimes it actually loaded normally (I even saw beta program warning/notice). But when I tried using it for more than a minute, it would freeze, reboot, and loop again.
What I've already tried:
- I tried using the WugFresh NRT fix softbrick method. I was able to quickly turn on debugging one of the times that I left it to loop. But when NRT sent a reboot the phone, it threw it back into the loop and NRT stopped recognizing the device.
- I tried to follow the unbrick procedure using a TOT file in this thread: http://forum.xda-developers.com/nexus-5x/help/tutorial-how-unbricked-nexus-5x-16gb-t3481766 But even after using LGUP, I still cannot even get into recovery mode.
- I filed a bug in the AOSP here: https://code.google.com/p/android/issues/detail?id=225802.
I'm at a loss here. On another thread, a member suggested this type of loop was a hardware/solder joint issue. I suppose that's possible... but man, what a coincidence that would be! Just now after the OTA the hardware fails? Any other thoughts? I'm pretty new to a lot of the terms/methods here, so maybe I missed something.
Thanks, DCK.
Update: I tried using LGUP again. The phone still gets stuck on the Google screen then boot loops.
Now, however, I am able to get into recovery mode consistently. Other threads have suggested doing an OTA sideload at this point. But I cannot seem to get my device recognized. The NRT shows no ADB devices connected. So I'm still stuck. Is there another way to try sideload?

Try fastboot/bootloader mode and fastboot flash the OTA manually.
Update 2: Seems like all the other things I tried over the last few days have caused various unofficial USB drivers to be installed. I've tried uninstalling most of them. I downloaded the google USB driver from latest SDK. But my 5X is still recognized as a Kedacom device when it is sitting at FastBoot.
However, I must have made some progress because I was able to start the sideload process. Unfortunately, I am now stuck on yet another error. The phone hangs at "verifying update package" and then after about 2 minutes... it reboots itself and starts looping again!
I thought I had it. So close. Now I want to throw the phone. Going to sleep, but would be grateful for any other suggestions in the morning.

use nrt to erase all partitions, then download 7.1 factory image, unzip and flash one by one the partitions.

Sounds like the boot loop issue many people have been having (the hardware/solder issue). It happened to me a few weeks ago after upgrading to Android 7.0. I got a replacement device from google.
If you're bootloader is locked, NRT or any other method to flash the factory image is not going to work. The only suggestion I have is to un-enroll in the beta program and hope your device will boot long enough to flash the ota Google will send the device to get back to 7.0. Note, this will wipe your device.

Same problem here. It can't be recognized after I reboot to fastboot. So I can't flash anything.
If the device isn't recognized try this http://forum.xda-developers.com/showpost.php?p=69273414&postcount=33. It's worked for a few of us with the same problem

Enter stock recovery then flash the full ota via adb sideload
