Hi Guys,
Hope to get some help here.
So i unlocked the bootloader of my one plus one and installed supersu + Twrp recovery. All worked fine until i decided to relock the bootloader.
I've put the device into fastboot mode and executed "fastboot oem lock" with twrp recovery still in there.
Now i am trying to unlock the bootloader again using "fastboot oem unlock" to be able to flash the stock recovery and having issues.
output of commands:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock
...
OKAY [ 0.004s]
finished. total time: 0.005s
C:\Program Files (x86)\Minimal ADB and Fastboot>
After this it boots straight to twrp recovery. I then hit reboot system and go back to fastboot mode and run the below:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery recovery
.img
target reported max download size of 536870912 bytes
sending 'recovery' (12260 KB)...
OKAY [ 0.389s]
writing 'recovery'...
FAILED (remote: Device not unlocked cannot flash or erase)
finished. total time: 0.404s
Anyone has an idea how i can unlock the bootloader again ?
Thanks
Vik
Would it let you reflash the stock factory image thru fastboot? Maybe if you could do that it would let you unlock again. And it would give you stock recovery.
Or else what about the option in developer settings to update the stock cm recovery when installing an update. Maybe you could install an official update thru TWRP and get stock recovery back?
Just throwing out ideas, hope you figure it out
I've documented ths same issue describe here: http://forum.xda-developers.com/oneplus-one/help/locked-bootloader-twr-rooted-t2820341

Hi YrrchSebor,
Thanks for the reply.. I already tried all that, even using adb sideload and keep getting same error as mentioned above. I'll try the solution lemonspeakers suggested later today and post the outcome.
Thanks

Be careful if you updated your phone to XNPH30O OTA,
!!! Warning !!!
In the NEW OTA CM11S XNPH30O, the bootloader (aboot) img size changed....
We request all not to apply the unlocker scripts on the new bootloader , until we confirm/find the new bit position.
It might brick your phone and corrupt bootloader...

It won't work.. do not try it if you updated to XNPH30O using the OTA.

I ran this command:
Code:
fastboot.exe boot TWRP-2.7.1.0.img
But the next step does not work:
Code:
It will boot your phone into recovery once from the recovery image
stored in your PC temporarily
then you can flash the zip either by sideload or from sdcard...
I got:
downloading 'boot.img'...
OKAY [ 0.484s]
booting...
FAILED (remote: Device not unlocked cannot boot)
finished. total time: 0.487s
That's because you can't boot a recovery with the recent bootloader unless you're unlocked.

I never said to enter "fastboot boot", try with "fastboot flash" and the result will be better Please read and read again before saying that TWRP is not working.

What do you mean by flashed wrong kdz? If you where running the latest version of MM you just bricked your device. You cannot downgrade downgrading tripped antirollback. Only fix is a board replacement.

NeverMind, used another laptop and i was able to do it... I think AMD has some usb filters or something
My Honor 6 was bricked after a stock OEM installing. I was tried to use fastboot to install a new recovery, but it shows
Code:
FAILED (remote: Command not allowed)
, however my phone says it is UNLOCKED.
Please help.
Thanks
