Hello
I did accidentally have a power failure on my computer when flashing version 4.0.4 to my Galaxy Nexus and the phone keeps booting on recovery menu automatically.
I have tried to flash different version using fastboot and Odin but always get an error saying my bootloader is locked use "fastboot oem unlock"
When try to unlock using the command the phone displays a selection screen asking to unlock the bootloader YES/NO, If I select YES the fastboot line returns the following error FAILED (remote: Unknown Partition) and the bootloader keep locked.
I have tried a thousand times without success and I am not able to utilize any firmware because is not permitted until I manage to get the bootloader finally Unlocked.
Pls help
Thanks
How about you
a) Flash an official rom via stock recovery and try it then
b) Ask this question in the Questions and Answers section instead of the Development section because I don't see any development relevant information in this post...

Try using the Gnex Toolkit posted on the development page as a sticky.
since u can't use fastboot (and the toolkit is useless in this case), i think u should try odin
THIS IS NOT DEVELOPMENT

First of all, use ANY toolkit (Mine's in the description ^^)
Then unlock your bootloader (Open cmdthe type:
Code:
fastboot oem unlock
You'll need ADB/fastboot drivers installed, though...)
There's no point using a toolkit, how it sounds to me is you somehow messed up a partition when flashing the update.
As someone already said try flashing an ota update through the stock recovery (if you have stock recovery)
It was probably the bootloader that got messed up when your power went.
Try flash a new bootloader too, see how that goes.
Fastboot flash bootloader filename.img
I am having the exact same issue. Trying to flash, format or dare i even say erase won't do anything to the bootloader, trying to access recovery on mine it says failed, trying to unlock the bootloader through oem unlock, prompts the failed : remote unknown error code. :S
use the galaxy nexus toolkit to unlock bootloader, root
Apparently the power outage messed up your partitions, causing the unlock command to fail. And since your bootloader is still locked, both fastboot and Odin cannot be used to flash anything. If you have root, you can try unlocking the bootloader with the bootunlocker app.
PS: advice that says 'use toolkit X' is pointless by the way. Toolkits are just GUIs around fastboot and adb, if the raw fastboot commands don't work, Toolkits won't work either.

Thats true, every tool kit i have tried has failed, even fastboot commands, at least the latter tell you that it fails. Where can i download the bootunlocker app? Does my Nexus 7 have to boot into the rom to do this? Because mine can't. :S

Incorrect.
Signed images will flash correctly with a locked bootloader.

Ask Google or Samsung, they have the keys to sign it. Also, this is the galaxy nexus forums.

OP, OMAP flash?
Is it possible to completely lock my my bootloader after unlocking it?
I used fastboot oem lock and now it says RELOCKED in fastboot. I also got rid of the security warning flag. Next I'd like to get a complete lock so I enter fastboot oem writesecureflag 3 which hangs the bootloader and doesn't fix my problem. has anyone yet been able to obtain complete LOCK?

Complete lock is NOT possible. That's the way it is.
not possible yet mate
Hmm shame, Thanks though.
Hi all, I need to relock the bootloader, flashing back stock MM or LP didn't solve the issue for me, neither hard resetting, bootloader is still unlocked and the message appears on every start in the high left corner.
Can You help relock or it's impossible for now please?
It's not possible to relock once it's unlocked. It does tell you this when u unlock it.

thanks for the answer, I did not remember that message. Strange for me that noone found or searched a method to relock for selling the phone :good:
Getting it relocked is the only way to send it back for warranty claim. I wasn't able to get it recognized by my computer so that I can run fastboot comands on it - the right one is ./fastboot oem lock

Did you use the proper fastboot.exe? What OS is your computer? If it's windows try these.
It seems that in order to get fastboot operational, you need to have a working bootloader. So, after a couple (hundred) of tries - DO NOT FLASH KDZ (REFURBISH) your LG G4, it still boots once in a while and if it has your account and data and it will be faster to get to fastboot mode and get the bootloader locked again. Can somebody confirm that you can execute "fastboot oem lock" on an unlocked device? This will save us a lot of time trying to get the device to that state...
for me it is impossibile. If you have a g4 with bootloader locked and you doing fastboot oem unlock it says that it is no possibile...you must follow the instructions that lg provides with file unlock.bin
So is impossibile relock bootloader with fastboot oem lock...I hope that anyone find the way to do it...
Well unfortunately it is not posible to lock the bootloader via "fastboot oem lock" I'm waiting for user @warloxfre for some more info on his ideas (fingerscrossed)
Solution to Lock Bootloader:- Go to Fastboot Mode,
Type :
fastboot oem relock (Bootloader unlock code without bracket)
I finally submitted my device to service centre
Needed a help in locking bootloader of Honor 8 Pro Indian Variant DUK- L09 C675.
I flashed Latest Oreo update through TWRP with the help of DUK_FullOTA_ROM_flasher method but the bootloader is still unlocked....
If anyone could help me with this as I have to visit service centre related to mic issue.
Connect to your computer, restart to fastboot mode and use "fastboot oem lock". Make sure you have a stock recovery and ROM on it, because the locked bootloader will not boot anything else.

Relocking bootloader by this method will erase all data?

No, it won't. But you should still have a backup whenever you mess with fastboot.
Hi I have the wifi only gt310 and when I go to developer options there is no OEM unlock feature. I can get to recovery though using power and vol up on boot. Im just wondering if I can proceed to flash a new rom or if I need to unlock the bootloader - as I have not been successful with finding those instructions on how to do this
I was able to use adb to see my device but fastboot bootloader restart did not work. It seemed to hang on waiting for device.
You don't need to unlock bootloader on wifi only versions
