It doesn't matter your bootloader locked or unlocked to boot your android in bootloader mode.
Try to boot in bootloader using adb commands.
If it boots via adb then try different key combination to boot in bootloader.

[Q] Unlock Bootloader on 4.5.141?

Currently rooted on 4.5.141, but pretty frightened of attempting to unlock the bootloader without reverting to an earlier firmware. Is there a proven method for unlocking the bootloader without downgrading?

So I got my 2.3.6 finally rooted, but now I'm having trouble pushing Cwm onto the device. I tried erasing the current recovery using moto-fastboot erase recovery and overwriting the current recovery via moto-fasboot recovery recovery.img with fail's both times. My last attempt was install Rom Manager and trying to auto install the recovery from there. It said it successfull installed, but when I attempt to boot into recovery I just get:
Failed to boot 2
Starting RSD mode
(hanging)
Any suggestions?

You rooted, but did you unlock your bootloader? If you have a locked bootloader, CWM will softbrick your phone IIRC.

I used these commands to gain root, but now that I look at it I'm not seeing anything that would unlock the bootloader for partitioning:
C:/moto-fastboot-win32
moto-fastboot.exe flash preinstall preinstall.img
“/bin/mount -o remount,rw /system”
“cp /preinstall/su /system/bin/”
“chmod 6755 /system/bin/su”
“PATH=/system/bin:$PATH pm install /preinstall/Superuser.apk”

What should I do to unlock the bootloader?
By the way I'm on 4.5.141 / 2.3.6

Huawei y6 can not boot help!!

If you do not have a bootloader unlocked, you will not be able to recover from the twrp recovery and unlock the bootloader again. Then you can install twrp recovery, install custom ROM, install gapps, reboot, and you can not boot?? please help!

Well.
Your phone doesn't boot anymore?
Does it boot to recovery?
You could factory reset maybe, if you can get to recovery, or maybe install an Update.app
Well if you have USB debugging, OEM unlock on, you can still unlock your bootloader
Go to www.imei24.com and write your phone Imei.
Now you can get some information that will help you get the bootloader unlock code.
After that go to: https://docs.google.com/forms/d/e/1FAIpQLSeGwoQ44zqykuTfjCQrVP07JOHBYnBcAxAbz9SAVxPTFqMh9g/viewform
And get your bootloader unlock code.
Now unlock your phone and flash twrp.
Make these steps only if you have USB debugging on and OEM unlock on, and if you can go into fastboot.
If I helped you, thanks button works well.

Locking and unlocking bootloader on stock ROM&Recovery

Hi!
What happens if you don't have permission to unlock bootloader and you still try to do it using fastboot oem unlock on Xiaomi Phones?
I have already got the permission and I've rooted my phone, so I didn't really try it because I was simply afraid. Has anybody tested that?
Also, if I relock my bootloader again using fastboot oem lock, will I be able to unlock it using fastboot oem unlock or will I have to use MI tool?
Aaaand the last question - I haven't installed custom rom or TWRP - I booted TWRP using fastboot boot xxx.img, then installed SuperSU package. Is it dangerous to lock bootloader with phone rooted? Recovery is still stock, so ....

Relocking Bootloader

Hi guys,
I got a bootloader unlocked ANE-LX2J and I want to lock it again but I dont know the next step.
I still have the bootloader unlock code and already flashed FULL OTA using TWRP and did factory reset.
So now, my P20 Lite is running pure stock again and ready to be locked right? or still not lol :silly:
Based on what I read here, after relocking bootloader using fastboot oem relock command, the warning/alert that shows when the device is booting is still there and I want to get rid of it.
Thanks :highfive:

Yes, you're ok to relock your bootloader if all partition and recovery are stock and your device is working without issues. After relock the recovery will do Factory Data Reset and no more warnings "your device has been unlocked and can't be trusted"
Boot into Fastboot&Rescue Mode and use this command:
Code:
fastboot oem relock [I][B]yourcode[/B][/I]
Then you enter into Lock Bootloader menu and just follow the instructions.
YES -
NO -

Does the Lock Bootloader menu will automatically show after relock command? I'll give it a shot later. Thanks :highfive:

it will show a red text saying your system has been tampered with and turn off..
you will need to restore a completly stock rom with sdcard before you can boot the phone.
