Bricked Galaxy Nexus automatically locks bootloader

Hi! The story goes like this:
A friend of mine gave me a bricked Galaxy Nexus to resurrect: the phone keeps playing the colors animations and never ends booting up, but I can enter fastboot and recovery modes.
Things I tried:
1) efrant guide to return to stock.
Here is the big problem: after doing the 'fastboot oem unlock', at the bottom it appears in red text 'LOCK STATE - UNLOCKED'. But then I do a 'fastboot reboot-bootloader' and it changes to LOCKED again, so I can't complete the steps because of this. I think this is what is causing all the troubles.
2) Flash JB package with Odin.
3) Flash ICS package with Odin.
This last two completed successfully, but the phone is having the same problem, there were no changes. The bootloader version is always PRIMEKK15.
Any hints? Maybe it's a hardware problem and there's no software solution? It's a shame, because I can access fastboot and recovery, but everything I tried doesn't seem to work.
Big thanks.

seems to me that the unlock token is not sticking somehow. have you tried relocking it right after you unlock it? for example, can you 'fastboot boot customrecovery.img' and enter cwm after you unlock?

Yes, if I do:
# fastboot oem unlock
# fastboot boot cwm-recovery.img
It enters CWM just fine. The problems seems to be that the changes are not persistent, or at least that's what it shows the info in the fastboot mode. Even after all the things I flashed, the bootloader never changed.
I will be trying to relock it right after unlocking it and I'll post the results.
Thanks.

You can try to use the GALAXY NEXUS TOOLKIT V7.8. It has many helpful features for unlocking, rooting, flashing factory images, or separate radio\bootloader images. User-friendly GUI are included.

He already knows how to use fastboot. There is no need for him to use a toolkit which does nothing different aside from hide the commands from you...

Guess he have his 10 posts now so he won't post for a while ^^

And don't recommend toolkits to people asking for help, 3/4 of the time they are clueless, recommending it to them will just make them sink deeper in to a god knows how deep pool of sh*t. No offence to you though, just don't recommend toolkits next time

Thanks guys.
I'm reading that people recommend doing an OMAP flash, but only when the phone is completely dead. I can get to fastboot / Odin mode, is there anything that I should try before doing an OMAP flash?

i think we already ran out of options. you could try omapflash... although i still think it's an issue with the unlock token/nand.

I've just tried that and it works as expected.
# fastboot oem unlock
*It says the bootloader is unlocked in the phone display*
# fastboot oem lock
*It says the bootloader is locked again in the phone display*
Then I tried flashing the ICL53F 4.0.2 stock image through fastboot, because it uses the bootloader that I have at the moment. It didn't work, it's still stuck at the animation colors. Look at the results, it all seems ok:

The only thing that caught my attention is the fact that the process lasted almost 29 minutes. I don't know if that's normal.

It isn't working, same result as always.
I'm new to this Android world, so I have to ask: could CWM or similar custom recovery offer some additional method to try? Because I can boot CWM recovery, but I don't know if can do something from there.
Thank you guys.

can we get a logcat of the bootloop?
anyways, if you flash cwm, does it stick? it doesnt, i assume. be reminded that /system/recovery-from-boot.p needs to be renamed or removed, if exists.
imo, using cwm to flash a rom won't do much here, given the current situation.

About the logcat, I've read that you have to use adb, but it never worked for me. When I do:
Code:
[B]# ./adb devices[/B]
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
<empty space here>
I can boot the CWM recovery. If I flash it, it doesn't stick. I don't know how to delete /system/recovery-from-boot.p, do I need adb?
I tried the OMAP flash, then tried to unlock the bootloader and after the fastboot reboot-bootloader, it gets locked again.
I'm reading lots of threads with bricked Galaxy Nexus, but never one with this behavior.

Only thing I can suggest is try fast booting a different bootloader version to a newer one.

OK then odd, the other thing I'd suggest is go to the Google factory image website https://developers.google.com/android/nexus/images then using mskips tool kit there is a feature to turn the .IMG into .tar (I think its .tar?) which can then be using in Odin mode instead. Flashing this way is different than fast boot and the Google factory images contain boot loader and radio and obviously a ROM.

That is because your ADB driver is not installed. It seems like you have the fastboot driver installed, but not the ADB driver.

Since you've already tried fastboot, odin and omapflash, I doubt anything else will work. The only other thing I can think of that could possibly work is for flash the bootloader using dd, but I doubt it. Most likely a hardware issue.

I'm on Linux, I thought that if fastboot is working, adb should work as well. I'm trying adb with the phone in fastboot mode, should I try in Odin or recovery mode?

Let's suppose the problem is the NAND flash memory, is it replaceable? Of course I'm not doing it myself, but I'm thinking if the phone has to be replaced by a new one, or can be repaired.

Oops, forgot you were using linux (so no drivers required). But ADB should not work your device is booted in fastboot mode or odin mode. It will only work when you are booted into recovery or into Android.

Not really. You would need to replace the motherboard as a whole.

[Q] Tried to come back from the Android L preview, now I have a bricked tablet

I was trying out the Android L preview, and decided that I've had my fun and wanted to go back to the ROM I was using. I booted into recovery, and noticed that the stock recovery had been flashed. So, I downloadeed the lasted TWRP and flashed it through fastboot. When I tried to boot into recovery again, it froze at the Google screen. Since I already had everything backed up, I decided to just flash the stock image and try again. This is where the real trouble begins. The flash failed (output below), and now I can't boot into android as well as recovery. I tried a few different images (all from the official site, all marked razor), as well as the Nexus Root Toolkit, and all give me the same error(s).
So, how bad did I mess up?

That error is usually due to an incompatible fastboot, first try doing a: fastboot erase system
...then try to flash system.img manually again.
Make sure you have the newest fastboot, one that is new as Android L bootloader.
NOTE: DO NOT erase bootloader! This will hardbrick you.
BTW, this is one of the reasons why I use multirom!

The only img file I have is the bootloader. Is what what you mean?
Also, that seems like a tool I should really have.

I assume you have the factory image for your old rom, in that package there is a zip file, if you extract it, you will find, among others, a img file named system.img. This is one of the files that is failing to flash.
The bootloader image is failing to flash because it is older than the one that is on there now (the Android L one), so fastboot does not recognize that new Android L bootloader because it expects one of the pre-L bootloaders, so you may have to grab the developers SDK and use that fastboot so it will recognize the newer bootloader.

I installed the SDK platform for Android L through the SDK manager, but I'm still getting the exact same error.
I suppose it's also worth mentioning that even if I try to flash the L preview, I still get the same error.

Well, have you tried this? http://forum.xda-developers.com/showthread.php?t=2381582
Read the whole OP, you can and should obviously skip the relocking of the bootloader.
Try the Recovery_Nexus7.bat first, if that fails then goto the Dead_Nexus7.bat.
It probably will get you nowhere, but it's worth a shot, obviously if it works, it will wipe everything and put it back to factory.

I solved this simply... By using Nexus Root Toolkit and using Flash Stock and Unroot. Went back to 4.4.4, but you can flash back to any version this way. It will download the ROM you want and flash it with you I having to do basically nothing.
If you are in a boot loop, there's an option for that right under the flash stock and unroot option.

Sorry for the absence. Had a busy few days.

Like I said in the first post, Nexus Root Toolkit is one of the methods I tried. There's an option to force flash, but I've been trying to avoid that, since it warns of hard bricking the device. I'm quickly running out of options though.
Update: Tried again with force mode turned on. No change in the results.

Installed TWRP, phone forever on boot animation. Need data from device

Hey, I haven't rooted my phone in years, and thought I'd try it to goof around with some stuff. When thinking of backing it up, I thought I had everything off of it that I cared about, only to realize afterwards that I don't have my recent videos of my child backed up.
1. I allowed for unlocking in dev options
2. Boot into fastboot mode
3. Flashed recovery TWRP 3.0.2 bullhead
4. Boot into recovery
TWRP asked me for my pattern to unlock my phone. I gave it the correct pattern, and it keeps saying that it's wrong and can't unencrypt. I gave up on flashing superSU since I couldn't boot, and now my phone won't boot.
I've tried flashing an older TWRP on (2.8.7.2) to try to get things back up and running, but no. Any help would be appreciated!

Did you forget to list a step you did like
fastboot oem unlock
That step usually warns you that it is wiping your user data.
If you want to get it to boot, I would do
fastboot erase user
fastboot format user
fastboot erase cache
fastboot format cache
Although I wouldn't do that until you are sure what happened in case there is a remote chance your stuff is still there.

I ran
Code:
fastboot flashing unlock
In TWRP, in the backup option it still shows that I have several 26 GB in my data partition. I'm having a hard time finding it's location in the adb shell though so I can pull the files.
So that will get my device booting again? What if I wanted to get it booting again rooted?

If TWRP says you have 26GB in your data partition available, then your data partition is probably empty.
I can't tell you 100% that will get you booting because I'm unsure of your exact problem.
I can tell you that one reason for the boot hang is if your user partition is erased but not formatted properly. What I suggested would fix that potential problem.
It doesn't seem like you'll lose any additional data you haven't already lost from the fastboot flashing unlock so it is worth a try.
I think the videos you were trying to retrieve are gone though from the fastboot flashing unlock forced factory reset.
BTW are you working with Android N or Marshmallow (6.0.1)? TWRP decryption doesn't work with Android N.

On the backup screen it says by data partition is 26019MB. I was interpreting that it was saying thats' how much data I have to back up. I guess your right, that it's not confirming that the data is there.

I gave up and decided the data probably wasn't there.
I'm trying to get my phone working again as root. I'm seeing 2 messages: a orange one that says my data might be corrupt, that's more of a warning, and a red one after running the super user script provided by twrp. I see the red one every time I try to boot.
After that I ran the commands you gave me. Here are the results:

Good call.
So I'm still seeing the red "Your phone is corrupted", however my phone tries to boot again, however it still seems to be stuck on the boot animation. Not sure where to go from here.

Flash stock boot and vendor images, then in TWRP flash latest SuperSU.

How do I do that? Where do I get the stock boot and vendor images from?

You can get latest image from here: https://dl.google.com/dl/android/aosp/bullhead-mtc19z-factory-9f649f91.tgz (this is stock Google firmware labeled MTC19Z from July)
After downloading, extract the archive, and run flash-all.bat (this script will flash all of the images for you, including data wipe, which can be disabled by removing -w parameter from the script).
Then, flash TWRP, boot into it and from there flash SuperSU zip.

I was able to boot into my phone following your instructions. Thank you very much. I'll try rooting my phone again after all the apps are restored.
It also seems that the auto backup on Google's "Photos" app saved all my pictures and videos. Thank you very much for your help. I really appreciate it

There is no partition labeled "user", type "userdata" instead.

Thanks for correcting. Going by memory but it isn't what it used to be.

Thanks everyone . I was able to get phone back in working order with root.

Bootloader Reports Unlocked, Unable to Flash Custom Recovery/Re-Lock Bootloader

Greetings,
So I suppose I made the mistake of not locking the bootloader before flashing the factory NRD91D image. Current situation is that my Pixel C is reporting unlocked bootloader but I can't flash TWRP. Fastboot indicates a successful recovery flash but when booting into recovery it comes up with the sad little dead android and "No command".
My goal is to get rooted N, obviously. TWRP would be nice.
I think I read somewhere that I can:
1. Flash factory 6.0.1
2. Flash TWRP
3. Wipe everything
4. Root
5. Lock bootloader
6. Flash factory OTA to N using Flashfire with SuperSU Injection.
I've been trying adb fastboot and I sprung for skipsoft hoping it could magically bail me out but no luck.
Anybody else stuck in this situation? Does anybody have 7.0.0 rooted with TWRP? If so what steps did you use?
Thanks in advance for any help or advice.

I been using Skipsoft and its saying the device is unlocked. The bootloader screen says its unlocked at the bottom, but also says no recovery OS is corrupted. I've tried to lock it with oem lock/unlock as well as flashing unlock. The system does not report errors while unlocking/locking, but I'm unable to flash anything.

These are most of the commands I've tried. This is on my mac. The windows machine SKipSoft will say it's unlocked, but during flashing will throw back that it's locked (bootloader reports unlocked)
I included photos to show it does say it locks/unlocks.
I contacted Google and that was a disturbing experience. Both times you can tell support is reading from a script. They both promised someone from 2 tier would contact me, so far nothing. I'm willing to pay to have the thing repaired, but sadly you need the 2nd tier person to call you to even find out if that's possible.

ok but you must wait that after lock/unlock bootloader the userdata is formatted automaticcaly!
reboot into fastboot
type fastboot flashing/flash lock and waith that userdata is auto formatted
flash stock firmware
if you dont do this the error still persist due to damaged userdata partition
---------- Post added at 10:17 AM ---------- Previous post was at 10:07 AM ----------
i want help you .... i ve got this error last month and i fixed with this.... follow this tut:
- use a pc with windows 7 installed
-download google usb driver ( adb and fastboot) latest
reboot device into bootloader mode , connect it and open terminal and use fastboot flash/ flashing lock ( now pixel c will automatic format userdata partition corrupted)
after the process is ended( 5/10 minutes) you are able to back to stock ... dont try to flash tpwr , first i reccomend factory image 7.1.2 august for pixel c
after flash stock reboot configure the sofware , go on setting and if the device is already unlock reboot info fastboot and flash tpwr ( fastboot flash recovery recoveryname.img)
i reccoment latest stable tpwr
actually i have this and i have resurrection remix latest + f2fs data cache+ xceed foolowsi kernel with fsync off, zen scheduler
very smooth and fast
every time you lock/unlock bootloader you must wait that userdata is formatted by device ( this during 5/10 minutes usually)

I pasted the output before to show that I've done as you suggested several times. It says its unlocked after the lock/unlock process (look at my previous commands). Once you input those commands, you hit power to say yes and the device will reboot. The below process is from SkipSoft Android Toolkit to better explain the issue as explained in the title of this thread.
Are you ready to start? Type y[yes] or n[no]:y
Device mode detected: Fastboot Mode
Device Serial Number:
Device Bootloader State: Locked
When prompted, Press the Power button on the device to Unlock the Bootloader.
If it is already unlocked then this will just be skipped and your device will not
be wiped. After unlocking the device will reboot to recovery to erase the device.

Unfortunately I jumped through many hoops with Google before then sent me a one time replacement. I sold the tablet and now I'm on a Samsung Galaxy Tab3.

As I said you will have to jump through many hoops. They will want you to email support, then you have to wait for a call back. Expect no one to be able to help you, even though they will keep bouncing you around. I'm not sure if its 100% guarantee they will send a replacement after a few contacts. If they do send you one, prepare to have them hold around $550 for the refurbished unit to be sent and the old one returned to them. I sold the new one as fast as I could on swappa, because of the lack of recovery options for the device and the messed up unlock/lock flag error that this thread is talking about.

Using fwtool command worked beautifully

I had a situation where I locked and unlocked in fastboot and still had TWRP recovery installed so the OS protection kicked in and prevented me from booting up normally.
I booted into TWRP recovery where TWRP has built in root access.
I copied the fwtool to the SDcard while the tablet was booted up normally using the PC but, if you can't boot up, ADB push command from a PC would have also placed the fwtool onto the tablet sdcard (adb push fwtool /sdcard).
I used the command adb shell and thus was sitting on the sdcard root where the fwtool was placed. I issued the fwtool command directly from the sdcard location. I did not copy the fwtool to any place else.
adb shell
fwtool vbnv write dev_boot_fastboot_full_cap 1
The command was successful and, I was then able to have full flash access back.

Sorry for the Resurrection. Can somebody explain how they fixed this, I have the same situation exactly. Access to TWRP and fastboot etc, but the dreaded FAILED (remote: unsupported command) stops me in my tracks. I can only lock and unlock the bootloader.

How to flash factory image?

I'm not new to flashing the images... But Jesus Christ there's a lot going on with the pixel... There's not just a system, vendor, boot, recovery, and cache IMG now... There's a ****load and I'm not sure how to flash them... And when I run the flash all.bat I keep getting an error during the flash and it just pauses... Same goes for the skipsoft tool. Anyone know how to flash these?

Drivers. Search on how to verify your drivers are up to date and installed.

Am I able to flash the images separately though? I do I have to use the flash all script?

Not usually.
And some dev's hate the bat due to Windows being stupid sometimes.
Many folks will flash individual files one at a time.
I however, am unfamiliar with the Pixel XL partition setup too, so I would totally wait for a higher level dev to come along and answer before I do anything.
I actually posted a similar question in the factory images thread over on the development sub forum for Pixel XL.

I am also having issue flashing the marlin-nde63p using the flash-all.bat with the 128GB Pixel XL phone from google. It keeps erroring out with the following [FAILED (remote: partition [boota] doesn't exist)]. Anyone know how to fix this?

Ok I literally just did this because I messed up my pixel xl 128gb after rooting it today.
First off I had my luck with minimum adb and fastboot, install it and go to your computer and find where its downloaded. (Ex. Mine was in C:> programs x86> minimal adb and fastboot folder). After you have located, find you image you just downloaded from Google and extract the files there should be 6 (I am a Verizon user and used the H update from the Google site). Copy all those 6 extracted files into that folder you located earlier (minimal adb and fastboot) and just click on the flash-all file you just dropped in there an sit back and let it do its thing

I had the exact same issue that you are having, another user on here recommended that I use the Unified Android Toolkit to flash the factory image. It works perfectly, and also has a bunch of other useful features (some will be more useful as the community figures out this system partition thing).
The toolkit is great and no necessary features must be paid for. This will solve your error issue. Best of luck!
Find the toolkit here: https://skipsoft.net/
