Updated to Android N preview - lost root - Pixel C Q&A, Help & Troubleshooting

Hey guys,
I updated to the Android N Developer Preview, expecting to have to root my device again. I tried following the instructions here:
http://forum.xda-developers.com/pixel-c/general/guide-unlock-bootloader-install-custom-t3307183
and my device already shows as unlocked. When I try and flash the custom recovery though, I get this message:
Code:
$ fastboot flash recovery twrp-3.0.0-0-dragon-ryu-02112016-1.img
target reported max download size of 268435456 bytes
erasing 'recovery'...
FAILED (remote: unsupported command)
finished. total time: 0.001s
Am I just out of luck with rooting the Android N version, and if so, is there an easy way to downgrade?

Even after downgrading, I get the same error, even when trying to follow the instructions on the developer.android.com/preview/download.html site. I get that error when I run the flash-all.sh script as well, when trying to flash the bootloader.

Are you sure to have fastboot/adb tools update ?

TLTR, lock and unlock your bootloader to fix the mess.

I did that, and now it just shows the "Bootloader is unlocked" warning and then after 30 seconds, shows the google logo, then reboots into recovery.

Yes, I have the most recent fastboot and ADB.

At this point, I have (I think) Android N installed, and I can boot into TWRP or fastboot or the menu that lets me choose recovery/fastboot, but I can't boot the system itself.

[Q] Nexus 7 2013 Problems...

A couple days ago, I was browsing the internet, then my Nexus 7 2013 suddenly froze. I did a reboot, but it got stuck on the boot animation. So, since it wasn't booting back up, I tried to load from one of my old backups. I managed to get the back up to work, however I needed to download the 4.4.2 update OTA through TWRP. It never officially said it finished, but I restarted the tablet and it's been stuck on the Google screen. I've went to fastboot, but it wont let me into TWRP recovery since it only loads the Google screen. I've also tried this ( http://www.androidbeat.com/2013/11/flash-factory-image-nexus-device/#.U0o0z3nn_0x ) and it didn't work.
When I try to reset through WugFresh, I've flashed KRT16S 4.4 and KOT49H 4.4.2, and and I get
Code:
sending 'bootloader' (3911 KB)...
FAILED (command write failed (Invalid argument))
finished. total time: 0.001s
rebooting into bootloader...
FAILED (command write failed (Unknown error))
finished. total time: 0.638s
archive does not contain 'boot.sig'
error: out of memory
I've also tried a few other ways of restoring to factory settings but nothing has worked :crying:
Any help is much appreciated!
I deleted my OS on my nexus... Oops? what I did is I did a ADB Sideload custom rom but if you can't get into twrp you are screwed. Maybe send it to Asus or return it if it is under warranty and get a new one. Just remember don't listen to me, in just a child on a tablet at night trying to unpack full posting privileges.

Couldn't you go into your bootloader, erase your recovery using ADB, and then flash it?

Alright, thanks I'll try this as soon as I get home. Though, when it says to type "fastboot flash bootloader bootloader-grouper-3.34.img" will I just be able to substitute the new 4.4.2 factory image stuff instead of the older? Also, does it matter that I can't set my Nexus into debugging mode?

Yes you will need to replace by the "bootloader-grouper-3.34.img" by the name of the img in your device archive.
For my Razorg / deb (The LTE version) it will be :
Code:
fastboot flash bootloader bootloader-deb-04.02.img
and
Code:
fastboot -w update image-razorg-kot49h.zip
And for the Razor / flo (Wifi version) it will be :
Code:
fastboot flash bootloader bootloader-flo-flo-04.02.img
and
Code:
fastboot -w update image-razor-kot49h.zip
For reminder, factory images can be found there : https://developers.google.com/android/nexus/images?hl=FR#razor
Debugging mode / ADB is not nessesary until you write the bootloader in fastboot mode
But don't forget to install drivers, except if you already do this step
I hope i helped you.

You mustn't flash grouper bootloader on flo/deb!
Only the bootloader that belongs to your firmware.
Yet I'm not sure if your USB driver is installed properly.
Are you 100% sure it is?
that link is great!...
Don't worry you are not screwed...just follow the link the person above posted about how to hard reset your nexus device. Since you have a 2013 nexus just make sure that you download the correct nexus image and make sure you flash the correct files and you will be fine. I have used that same tutorial on my nexus 7 2013 flo and deb to fix issues.
Trust me it will work...

The files in folder look fine now
Did you update your SDK manager to the newest version? (Especially sources regarding API 18 and 19 are important). Move the firmware files elsewhere before, because by major updates whole platform-tools folder will be replaced.
Try to use different USB port on your PC. Once when you are in fastboot mode, does this command work?
Code:
fastboot reboot-bootloader

Well, just my 2 cents... I read somewhere else on this forum from someone having the same issue that replacing the cable he used actually did the trick for him. You might try that. Won't hurt..

I haven't updated the SDK. So when I do, just be sure to move the image files and whatnot, and then put them back after the update, correct?
I'll be doing this later

Yes just move your firmware files (bootloader and image.zip) out of the folder.
Updating is easy, double-click SDK manager application (you will see it as soon as you open SDK folder) and there you can choose what to update. You just need an internet connection.

i am intrigued to see if this person was able to fix his tablet...
I think that all the suggestions above are very good ones. Making sure he has the most updated software...
Make sure he tries another usb cable or make sure you are using the stock usb cable.
And trying another usb port...
However from this fastboot devices output it did show that his device was connected which i don't think would happen with a default usb cable.
Okay so here is what i think may be causing the problem.
I think you need to unlock your bootloader before you can erase it. Try following this tutorial -> http://forum.xda-developers.com/showthread.php?t=1907796
You have to unlock it before you can erase the bootloader. So you need to do:
command 1: adb reboot-bootloader
command 2: fastboot oem unlock
then you can do:
command 3: fastboot erase boot
try that and see if that helps....
If that does not work then try flashing the new bootloader over the old one.
I hope this has been helpful.
Don't give up...
-droidshadow
LOL, good point @droidshadow!
Hey, @PieceofSlice, is your bootloader possibly still locked? Please make photo of the text in bootloader mode on bottom left and post screenshot of it.

So I actually tried to do this because, even though I updated the Android SDK, when I typed in "fastboot erase boot", it basically froze on "erasing bootloader." When I tried the first command, "adb reboot-bootloader", it said
Code:
C:\android-sdk\platform-tools>adb reboot-bootloader
error: device not found
So I take it I have a problem with ADB or something?
There are two generally different modes by using Android Debugging Bridge:
1. ADB (device booted in OS or recovery)
2. FASTBOOT (device in bootloader mode)
When I tried the first command, "adb reboot-bootloader", it said
Code:
C:\android-sdk\platform-tools>adb reboot-bootloader
error: device not found
So I take it I have a problem with ADB or something?

So, if you have tried this command above when your device was in bootloader mode, it was wrong command, as the command should have started with "fastboot...." instead of "adb..."
If the device was booted in OS, this command would have been correct and such response could have two reasons:
* USB debugging was not enabled
* drivers are not installed properly
After updating SDK manager, it is always highly recommended to check if the driver still works.

Careful, mate, I hope you didn't try to erase your bootloader? That would have fatal results. Actually "boot" means kernel! As long as your bootloader is there = your tab will be fine.
By flashing a factory image the order of doing things is
* erase all (kernel, system, userdata etc)
* flash new bootloader
* reboot bootloader
* flashing whole factory image zip file

HTC One M8 Root failed - Australia

Hi there,
I have just tried to root my HTC one, and I am now stuck in the boot loader screen and it is showing *Tampered* at the top.
Can someone please advise me, or point in the direction of what I need to do now?
Thanks.
If it says tampered it should say unlocked right below it.... go to this site and follow the instructions to get full root. http://forum.xda-developers.com/showthread.php?t=2699065

Once you have unlocked your bootloader then it will show you tampered.
Download a custom recovery (I prefer TWRP) and flash it via fastboot.
Then download @Chainfire Supersu flashable zip from his site and flash it in recovery.
You have rooted your phone.
Ater placing my device into fastboot mode, I have tried flashing my downloaded TWRP file to my HTC One in Terminal using these instructions:
Now let's flash your downloaded TWRP file to your HTC One. Type one of the following commands into your terminal window, depending on which file you downloaded above.
For the International editions, type:
fastboot flash recovery Desktop/openrecovery-twrp-2.7.0.2-m8.img
However I get the following error:
command not found
any help would be most appreciated.

hi,
plz try CWM, M8 got some issues with twrp.
philz_touch_6.26.6-m8.img is the stable version plz try that.
http://goo.im/devs/philz_touch/CWM_Advanced_Edition/m8
So I am starting to move forward :
I have followed the instructions to install philz_touch_6.25.5-m8.img by flashing it to my HTC where I get the setup screen for philz_touch_6.25.5-m8.img. I cleared the cache and I then installed the UPDATE-SuperSU-vx.xx.zip using the install zip from sdcard and then rebooted the HTC.
Unfortunately I have come back to the bootloader screen.
For what the instructions say it should be working now, but it does not seem to be?
Now it seems that whatever I try I cant seem to get past the bootloader....
And when I power down from the bootloader, It shuts down for a few minutes and then boots back into the bootloader.
Not sure what to do now?

May be you are using the wrong version.If you have international device you should try international version of philz/cwm recovery.I would suggest you to use TWRP since it is basically meant for htc devices.

[GUIDE][FIX]Cant unlock bootloader? Read here for a Fix

Hey guys , here's a simple guide on how to unlock your bootloader without having to downgrade all the way back to 2.17, in my case i had 2.17 system since it was the most stable(2.18 is a cluster hell of bugs) with 2.18 bootloader and recovery(yes you can mix and match)and so i went to try the bootloader unlock with just flashing the 2.19 system.img, that dint do anything the "getprop ro.isn > /factory/asuskey" command would do nothing, the bootloader wasnt unlock and so i did the following:
1.Downloaded the2.19 ota manually here link
2. I extracted the droidboot.img(fastboot img) from the 2.19 ota zip
3.Rebooted to fastboot mode
4. Then ran this command "fastboot flash fastboot droidboot.img"
5,After this i rebooted back into system and rerun the unlock bootloader steps and viola the bootloader unlocked!( it wasn't before simply because the 2.18 fastboot does not have this unlock command)
6.After you unlock the bootloader your device will most likely get stuck at the bootanimation screen, at this time reboot back into fastboot mode and downloaded the black splashscreen here and run "fastboot flash splashscreen splashscreen.img". then reboot back to system and your device should boot all the way into your homescreen and your done =]
All credits go to ssj and shakalacas(ota links splashscreen link) for the bootloader unlock.
THIS WILL NOT WIPE ANYTHING ON YOUR DEVICE, if you mess up the commands thats on you follow the guide properly and everything will be fine.

Also, I have model number ASUS_Z00AD. Is this firmware OK to install on my phone?

This is probably a silly question, but I have the ZE550ML and the latest update is 2.18, meaning that unlocking the bootloader it is still not possible can I install droidboot.img(fastboot img) from the 2.19 ZE551ML on my device? Or that will just hard brick my device?
Let me know your thoughts on this.
Continue the great work XDA crew =)
I am on 2.18 and can't seem to find any way to update to 2.19, all the links are dead.
so I rooted and flashed droidboot, but when i run the adb commands it says unlock failed and restarts
any help would be greatly appreciated

You need to flash the pre rooted 2.19 system.img, then you will be able to unlock, since 2.19 has the unlock files in system.

I copied the droidboot.img to my working directory, and tried to flash it.
Code:
C:\myworkingdirectory>fastboot flash fastboot droidboot.img
target reported max download size of 536870912 bytes
sending 'fastboot' (14410 KB)...
OKAY [ 0.661s]
writing 'fastboot'...
FAILED (remote: Permission denied
)
finished. total time: 0.826s
Ok, I got the error. Maybe the "unlock" command will work.
Code:
C:\myworkingdirectory>fastboot oem shell_cmd "getprop ro.isn > /factory/asuskey"
...
OKAY [ 0.203s]
finished. total time: 0.204s
Same output as the last hundred times I tried to run it.
I rebooted the phone.
Code:
C:\myworkingdirectory>fastboot reboot-bootloader
rebooting into bootloader...
OKAY [ 0.108s]
finished. total time: 0.109s
I put the phone into the bootloader mode. (For anyone reading, to get into the bootloader, turn the phone completely off. Hold the power button until it vibrates. Then hold the volume up key.)
I ran the unlock command twice.
Code:
C:\myworkingdirectory>fastboot oem shell_cmd "getprop ro.isn > /factory/asuskey"
...
OKAY [ 0.291s]
finished. total time: 0.326s
C:\myworkingdirectory>fastboot oem shell_cmd "getprop ro.isn > /factory/asuskey"
...
OKAY [ 0.216s]
finished. total time: 0.216s
Then I tried to flash the image again.
Code:
C:\myworkingdirectory>fastboot flash fastboot droidboot.img
target reported max download size of 536870912 bytes
sending 'fastboot' (14410 KB)...
OKAY [ 0.690s]
writing 'fastboot'...
OKAY [ 0.692s]
finished. total time: 1.384s
No error?! I have progress!
------
I believe my bootloader is unlocked. Let me try to flash the recovery. (My recovery was corrupted longggg before doing this.)
Code:
C:\myworkingdirectory>fastboot flash recovery recovery.img
target reported max download size of 536870912 bytes
sending 'recovery' (11676 KB)...
OKAY [ 0.579s]
writing 'recovery'...
OKAY [ 0.571s]
finished. total time: 1.153s
No permission error! (Before this, I would usually have gotten an error that says "FAILED (remote: Permission denied".)
---- Important Notes ----
NO WHITE BACKGROUND IN BOOTLOADER.
Many people have reported seeing an inverted background in the bootloader. I don't have that.
TRIPLE DOTS IN COMMAND PROMPT
The triple dots you see when I run the unlock command are actually there. They are not placeholders.
------------
Right now I'm booting into recovery mode to flash a ROM to the phone. I'll update if I get the phone working.

Moto Z2 force constantly bootlooping, Stock rom load but NO Wi-FI or Cellular network

I have struggled to fix my bootlooping problem , After install LOS rom/ other rom and flashing the Magisk. Everything installed fine, but for some reason, after restarting the system it will get to LOS loading screen and bootloop. I attempted to install a stock rom on it, but that load fine but it WIFI and Cellular Network doesn't work. The boot loader has been unlocked Any detail instruction will be highly appreciated. Thanks
Background info, I have spent more than 1 years using this awesome phone with Lineage OS 15.1 , I wake up one morning with the constantly boot looping. I have the T-Mobile version with the bootloader unlocked. I have also spent weeks going through and following other threads but haven't been able to resolved my issue.

Whenever you move from custom to stock and vice versa you should format user data. Easiest way is in bootloader mode, issue the command 'fastboot -w' w/o quotes.

Do you have an imei number still? Is the bootloader still unlocked? Have you tried following the return to stock thread and doing a clean install of the latest TMO firmware?

The IMEI number is “Unknown” , Yes the bootloader is Unlocked because, I am able to flash TWRP image on the phone. Yes I spent close to a week following the return to stock thread, the first time I did it, the Cellular network come on about 30 minutes after the phone completed loading to the home screen. Thanks for the guidance
You need to blankflash, then flash the latest TMO firmware for your phone. Usually you lose baseband when you flash the wrong firmware, does it say XT1789-04 by the usb port?

What zip did you use?
Edit: that thread uses AFH which has an older version bootloader than in your picture so something isn't going right. How long does it take to flash?
Edit 2: does your phone reboot after running the .bat file?
I used the T-Mobile Flash All zip the link was to google drive https://drive.google.com/file/d/1Bo_ry_38J6BHy4-A4fuhAnv94C5yV1TW/edit

Yeah, that one is old. Try https://androidfilehost.com/?fid=11410963190603877456 just like the guide states, it should open command prompt and you should see it flashing. The process can take s minute or two. If it immediately closes within 30 seconds or hangs, it didn't flash

Flash again, after it is done, type fastboot --set-active=other and then run it one last time. Then boot your phone.

After flashing the rom again, and getting the error " Erase successful, but not automatically formatting..." I input the fastboot command "fastboot --set-active=other" and I got back "unknown option -- set-active=other" as show in the image below. Was the syntax right?
I have been googling the errors I have received like "Erase successful, but not automatically formatting.
File system type raw not supported" to see if I can land on page that can help resolve the issue with the phone.
I have downloaded the latest adb and fastboot platform tools versions, after running the flashall.bat file, I still got the same error at the end. I follow up with the "fastboot --set-active=other" command and this time I got [ Setting current slot to '`' FAILED (remote: '') ] as show in the image below.

Seems it isn't recognizing other then, which it should. Do =_b then to see if you can swap to slot B

After inputting the command [ fastboot --set-active=_b ] the output I got back was [ Slot _b does not exist. supported slots are:
a
b ]
I proceed to input [ fastboot --set-active=b ] the output was [ Setting current slot to 'b' ]
So I the flashing again and input the [ fastboot --set-active=b ] again and got back [ Setting current slot to 'b' ]
I pressed the power button to start the phone from bootloader menu , the phone boot-loop with the Motorola logo as show, after 6 to 8 cycling of the boot looping with the Motorola logo the phone bootup again with T-Mobile logo. When it got home screen, I saw again that Network and cellular still not working and No IMEI number too.
