Hay, i have problem. Previously, my phone was successfully unlocked, but tonight while charging, it went into the bootloop by itself. I tried to make Wipe through TWRP, but it did not work. After installing TWRP 1, I made a backup of all the firmware except for the Data section.
I tried to restore this backup, but it did not bring any result either.
I went even further and decided to completely repeat the unlocking process, which was my fatal mistake. Now I have a bootloader locked.

According to this instruction, I reach the bootloader, in adb I drive the command "fastboot oem unlock" on the screen pops up an offer to unlock it, select "yes", the phone reboots into the bootloader and the bootloader itself is in "lock" mode.

Hello guys, a friend of mine has a galaxy nexus with some problems.
When I turn on the phone, it starts booting normally, but a few seconds after getting into "desktop" it starts popping up errors saying that the process as stopped.
I've already tried a few things, but without success. I'm running out of ideas and here I'm asking for your help.
Things I've tried:
-Boot into recovery mode and wipe all data.
The phone says that the operation completed successfully, but after rebooting the phone remains the same. All apps, wallpaper, lock screen, etc. It seems that nothing was changed by this process.
-Flash a original google ROM
Following the tutorials, the first step is to unlock the bootloader with fastboot oem unlock. The phone shows a confirmation asking if I want to unlock it, I say yes, and it shows "status: unlocked". But after rebooting the phone it is locked again!!!
I tried to flash the room without rebooting the phone after unlocking it,
Code:
fastboot flash bootloader bootloader-maguro-primela03.img
fastboot reboot-bootloader
sleep 5
fastboot flash radio radio-maguro-i9250xxla02.img
fastboot reboot-bootloader
sleep 5
fastboot -w update image-takju-imm76i.zip
The first command to flash the bootloader also says that completes successfully, but when I'm flashing the radio it will complain saying that the phone has the wrong bootloader version installed.
-Flashing via Odin
It fails when is flashing system.img to the phone
-Flash custom recovery - fastboot flash recovery recovery.img
The process completes "successfully" but when I boot into recovery mode, there is the original one and not the one I just flashed.
-emmc brickbug - partition scanner
I found this thread http://forum.xda-developers.com/showthread.php?t=1823918 and tried to run the partition scanner. As I can't have the phone on enough time to use adb shell, I tried to use this scanner via adb sideload but the phones returns an error when running it. (probably because it doesn't have busybox installed, not sure)
After trying all of steps above, the phone is still the same... nothing changed. Once, I managed to connect it to the pc as an usb storage device, and was able to copy some photos from the phone and deleted them. But after rebooting they were all there again. It seems that all write changes are not persistent.
I'm out of ideas now... Do you have any idea of what is the problem? Or any suggestion for me to try?
Thanks in advance
I believe that there is a script in the android SDK tools called flashall.bat which will reflash the kernel, bootloader, recovery, ROM ect. I'm not sure how to use it, but you could potentially try that
Hi, thanks for you suggestion, but unfortunately it didn't work.
I had a look at the flashall.bat script and it runs the same commands I run manually.
I think that the phone might have some hardware problem... Normally I would buy a new phone, but I'm trying to fix it because it is important for my friend and for me because it is challenging.
I guess that the next thing I will try, will be trying to run emmc_find_brick script by @hg42 via sideload
Try formatting /system and reinstall android. Power your device into bootloader mode. Make sure your device is unlocked. Also, make sure you have the factory image downloaded. After your device is plugged in into your computer, use this fastboot command: fastboot erase system. This will delete everything from /system. Also format /data and /cache: fastboot erase data and fastboot erase cache. After that, try installing the factory image again.
As title says, but we need a working backup. Mine is broken, can someone upload a working one, plz?
This is the howto:
1. Flash a stock image (I used the August stock image MTC20F)
2. Fastboot flash TWRP 3.0.2-0
3. Boot into TWRP
4. Select Wipe -> Advanced Wipe -> Select and repair each partition individually (some won't be able to, and that's fine, just move on to the next one)
5. Restore a full nandroid backup (make sure everything is selected) and reboot
6. You should now be free of the never ending boots, and if your device is bootlooped at this point (stuck at the boot animation), you can just flash stock again.
Thanks for this solution. But I have a problem because after installing the rom file .tot have a locked bootloader, and at this moment I can not do flash twrp.
In order to unlock the bootloader command "fastboot oem unlock" I get the answer that it is not possible. NTR it can not unlock it.
Goes some way to upload twrp with a locked bootloader or a way to unlock?

My bootloader is locked, too. The only way to write to the phone seems to be via download mode, but flashing LGH790AT-00-V10f-NXS-XXX-OCT-03-2015-32G-MDA89E-US.tot doesn't work...
To install twrp we need to unlock the bootloader.
However, when the command "fastboot oem unlock" system gives the answer
FAILED (remote: oem unlock is not allowed)
Then how to unlock?

There's really nothing you can do to force an unlock. If you can adb sideload a full OTA zip (say for 7.0) from Google and get that to boot up, that's pretty much your best bet.

I mean, the new unlock command is:
fastboot flashing unlock

On Nexus 5X both commands can be used (oem unlock and flashing unlock)
I followed all the steps except I can't boot to recovery...when I try (manually via ADB or automatically using Wug's tool) it just goes back into the bootloop. I can't even boot temporarily to recovery (without flashing). I'm getting close to throwing in the towel...
Did not work for me, sadly
Edit: Here's how I managed to fix the problem
1. Moved Nandroid backup to PC.
2. Download factory image MTC20F from https://developers.google.com/android/nexus/images.
3. Install factory image (This will erase all data on your phone so move your files to your PC).
4. Install TWRP 3.0.2-0 from https://dl.twrp.me/bullhead/twrp-3.0...lhead.img.html via fastboot.
5. Go in TWRP>Wipe>Advanced Wipe and repair all partitions that can be repaired (System, Data, Cache).
6. Restore Nandroid backup.
7. Success.
Hope it works for other people too, cheers
Anyone in Portland Oregon and want to take a crack at unbricking my 5x? LG gave me an RMA, but given it's not a hardware issue, I'm thinking it will be a waste of time to send it in -- I'm worried they'll just say "all your hardware is fine". Happy to buy drinks or pay a bit if someone can get me up and running.
Hello all,
I have Zenfone 2 on which I intended to use a custom ROM.
So the first thing was to unlock the bootloader.
On previous occasion, on my Nexus, I had used the - fastboot oem unlock - command and it had worked. So with that in mind, I booted into the bootloader and tried the command, but it failed - saying oem command unrecognized.
Then I searched online and apparently, to unlock the bootloader, Asus has launched an app! But to be able to install the app, I need to get a normal boot happening, which is not happening now.
In between all this, I tried the commands - fastboot flash recovery <recovery.img>, fastboot flash boot <boot.img> too. But none of these were successful, and each of them returned a 'Permission denied' message, probably coz the bootloader was locked.
Now the situation is that -
- Bootloader is locked.
- Phone is stuck in bootloader
- There is no recovery installed. In fact, from the bootloader, when I try to boot into 'Recovery Mode', it goes there for a second and returns back to the bootloader. Doesn't show the normal android image with a 'X' on top.
- There is no root access.
Now I think the first step is to get root access, and for this I want to try the method with installing CWM recovery and SuperSu.
But for this, I need to be able to push the SuperSu.zip to the phone, which I am not able to.
Can somebody please help!
r the drivers for fastboot & adb update to date?
Android version?
If the phone is stuck in bootloader, you can use Asus Flash Tool to flash .raw files and unbrick the phone.
Raw files: https://yadi.sk/d/FijRoAVJtvRiG
AFT: https://yadi.sk/d/NQCiY--IsQjBr (I use AsusFlashToolInstaller1.0.0.14.exe).

Hi,
I am using my Nextbit Robin Oem Unlock from last 1 year but today i decided to go back to stock with locked Oem.
I flashed the stock rom and locked the Oem at the same time but when i restarted the phone it got stuck at the boot.
So I went ahead with the 'fastboot oem unlock' command, and here's the problem. All flashing command returns FAILED <remote: device is locked...>.
fastboot oem device-info reads: Device tampered: false, Device unlocked: false. So bootloader is locked. At this point I assume that the bootloader is unlocked, but revert back to locked after reboot (the phone automatically rebooted after executing oem unlock command, so can't get around that).
Tried numerous other methods, using different adb files, no dice. Can't even flash TWRP. Tried adb sideload, same. Tried executing fastboot oem unlock with various different parameter, still locked after reboot. I cannot flash anything into locked bootloader.
Google researched it for few hours, same problem happened to other phones from other manufacturers that came returned from warranty replacement with modified motherboard; OR tampered/broken eMMC/NAND flash. But no such case for Nextbit Robin (yet?).
Pretty hopeless right now since I just found out that Nextbit Robin support ended on Aug 1st.
Guess I'm stuck with locked bootloader and no cell signal phone. Unless someone can help. One can always hope.
Anyway, thanks for reading.

If you bootloader is unlocked I think you can give a try to the Nextbit's Unbrick Tool
As you want to go back to stock , I think this is a good idea.
Now if your bootloader isn't unlocked there is unfortunately nothing I can do for you , unless you unlock it .
Edit #1: If your bootloader is locked , go to bootloader mode by pressing volume down + power button for about 20 seconds and try to see the bootloader state with fastboot commands. If it is unlocked , follow the process in the @nextbitKhang's thread .
Yes that's the main issue. Oem is Locked.
Is there any Oem unlock code i can use to unlock from ADB?
I don't think so ,I'm not sure, but I hope you'll find one.
On your Robin go to settings > system > about phone > tap build number until it shows developer options.
Go into developer options which is in settings > system > developer options.
Make sure OEM unlocking is enabled. (for good measure disable then re-enable)
Also make sure usb debugging is enabled. Have the Robin plugged into a computer so you can enable to pop-up on Robin asking for access for the computer.
Once they are both enabled shut down your phone. Turn it back on while pressing vol down+power and plugged into your computer.
In adb run command fastboot oem unlock
please i'm experiencing the same issue not on nextbit but on GIonee.
i have re-activate both OEM unlocking and USB debugging several times but it all void
same error: Remote: OEM unlock is not allowed
please kindly help
I was attempting to update my unlocked and rooted phone to 9.0. Did the usual process of extracting the factory image and removing the -w from the flash all script.
Used fastboot to attempt to flash the update and it seemed to succeed. I then attempted to reboot the device, but it began to bootloop many times just after the G logo appeared. I shut down the device and when I turned it back on it went to the bootloader screen.
Now when I tell it to start it simply returns to the bootloader screen. Fastboot and adb do not detect any devices. If i send it to recovery and attempt to perform a factory reset it says it goes through, but after rebooting it then returns to the bootloader screen. It also says my device state is still unlocked, which seems like it shouldn't be the case after a successful reset.
Any help would be greatly appreciated
I think that you should try reinstall your adb and fastboot drivers and use deuce script. You can try also small things like changing USB slot or rebooting your computer. Hope that I will help you.

First, reset won't change lock state which is good.
Power it off then hold power and volume down. That will get you to fastboot mode. Since you already reset it put the -w back in and flash it again.

My device isn't showing up in fastboot or adb so I'm not able to send it any commands. I've tried different computers and ports.

Resolved. I was eventually able to access fastboot via the skipsoft toolkit. Unfortunately, still not certain what caused the initial issue.
