I had rooted and installed cm13 on my phone Zuk Z1 almost 3 months before. But due to some hardware problem I had given the phone to service center and they have roll backed the os to cm12 and I think they have unrooted my phone.
The problem now is that when I'm trying to root it using ADB "fastboot -i 0x2b4c oem unlock-go" it is showing
OKAY
FINISHED
But my phone is not being rooted or rebooting
Also I can't flash any custom recovery on it.
Done by locking the bootloader and then again unlocking it

Weird thing happened.
I had the Nexus 10 stock for almost an year now (I unlocked the bootloader an played with ROMS and root after the release of 4.3 then bring it back to stock)
Now I wanted to sideload the OTA and unlock the bootloader (since i was planning to wipe data anyway)
Well I tried fastboot oem unlock as ususal and the procedure was a success "fastboot status okayoem". I restarted and bootloop. To solve it I had to wipe data factory reset from (stock)recovery and lock the bootloader again.
I sideloaded successfully kitkat with the bootloader locked using "adb sideload blahblah" and it works.
Still I wanted to unlock the bootloader.
Same "fastboot oem unlock" same success,
same bootloop
Why I can't unlock the bootloader without resulting in a bootloop?
Hi everybody
My Zenfone Selfie after a normal update (never modified) is in bootloop.
So I installed adb and fastboot and I flashed the twrp.
Then I tried in every way to flash a rom. I've tried both with official firmware and with various versions of cyanogenmod. Through fastboot and via adb sideload.
Even if seems to work, when I reboot I get the bootloop problem again.
As far as I can understand the problem it’s that I have the bootloader still locked. The official apk solution I guees it’s not applicable in my case. By fastboot oem unlock i get an error message (probably why i can not enable usb debug).
Do you know of other ways to unlock the bootloader or in general to flick my phone?
Thanks to everyone for the help
Hi,
When i received my Zuk Edge few months ago I unlocked the bootloader and flash a custom ROM. But it was buggy and i prefered to returned to the stock ROM.
So im now back in Stock ZUI Rom, no root, no custom recovery, no custom rom/firmware... The only thing remaining "unofficial" is the bootloader, which i "unlocked".
How can I lock the bootloader of the Zuk Edge ? (i mean relock it)
Cause i didn't find any post on that subject
Thank you all
I found the answer actually on ZUK Fans Forum.
You have just to :
/!\ Be on Stock ROM (ZUI Official) /!\ (otherwise, you'll brick the phone)
- Go to fastboot mode (adb reboot bootloader)
- Type this : fastboot -i 0x2b4c oem lock
Then the device will restart (it will be a bit long, no worries)
The bootloader status won't be unlocked unfortunately, but "relocked".
Hi,
but with "relocked" bootloader, OTA Updates are not able. I made same step/mistake and unlocked the bootloader with the aim to get OTA Updates, but now there is no way cause of the really bad description I followed... (
Is there any solution to lock the bootloader again? Maybe editing the 'unlock_bootloader.img'?
Sincerely yours

Hi guys,
I did something pretty silly yesterday while trying to unroot my phone.
First I uninstalled magisk
Then I disabled unlock OEM from developer options
Then from fastboot I did: fastboot oem lock
And then I restarted without flashing the stock rom...
The result is that I now have a locked bootloader, that does not boot to the ROM because previously rooted (it says device is corrupted), and I am unable to unlock to the bootloader because it is not enabled in the developer options.
I have no clue what to do... I can't flash anything because the bootloader is locked but I can't unlock the bootloader because the device wont boot...
Have I managed to reach the ultimate brick state ??? Please gib help.
nevermind boys I did a factory reset from the bootloader, and I started booting afterwards...funny because it did not work before, maybe it's because I attempted a rescue with the Lenovo smart assistant...dunno
Hello all! I have been trying to unlock my bootloader on my SGP311. I have searched the threads, followed the instructions, and still have problems. i initially looked at my service menu to determine if it is unlockable and it said yes. I then went through the steps to unlock it and it kept saying failed. Then, it finally worked, and my tablet rebooted. i got dual recovery loaded and then proceeded to wipe and install lineageOS from recovery. recovery kept failing to install the new rom. i then had to reflash a stock rom because the tablet wouldnt even boot into recovery again. now my service menu simply says rooting status: unknown and says nothing about the bootloader. What the heck happened?

You can't install LOS Rom from the dual recovery (XZDR). By flashing stock ROM, you bootloader may be locked again.
Check this guide to unlock it, and install LOS.
It simply will not let me unlock the bootloader anymore. And I can't seem to find a firmware that I can flash to get me to the appropriate version
so far, part of the problem is flashtool in androxyde still using the command fastboot -i 0x0fce oem unlock 0xkey. windows 10 denies this command every time and should be fastboot oem unlock 0xkey. But even doing so manually through the cmd prompt, it still will not let me unlock the bootloader. does anyone have a ftf file that has an unlockable bootloader? seems mine locked up completely when i reflashed the rom

bootloader is in device, not in firmware, so no such firmware exist you ask for.
