So I have got my phone in the bootloader and I want to unlock it so I type fastboot oem unlock <KEY> and I get this

D:\Minimal ADB and Fastboot>fastboot oem unlock ***************
(bootloader) slot-count: not found

Answer 1

Try this:- (Note - This worked for me till Android L,M and N on Qualcomm's MSM chipsets)

1. Enable developer Menu from Settings
2. From Developer Settings Enable OEM Unlocking
3. adb reboot bootloader
4. fastboot oem unlock-go
5. Device will reboot
   Partitions will get unlocked

Can you help me find the documentation for this? I can't find fastboot oem unlock-go anywhere. – Oculist

Hi @GabrielFair : Unfortunately I donot have documentation for this.. this was bit of a tribal knowledge that just happen to work ! – Cratch

fastboot oem unlock-go says < waiting for any device > and thats it. The emulator doesn't get any popup as well. – Aruspex

Answer 2

1. Boot normally
2. Enter Developer options
3. Some option as OEM unlocking should be there. Enable it
4. Proceed as you were doing in fastboot.

Hope it helps!

What if it is "bricked" and does not boot? Can't I change this "setting" using fastboot? – Monet

Same question @Olaia, can you have any option from adb? – Noway

@AndréCaldas any luck with fastboot? – Noway

@SaadBilal: It was not for me. I didn't try anything. But I guess that you can use fastboot and burn the original (some signed) firmware. Then boot, then follow the instructions above to unlock. – Monet

You might be able to change it from fastboot if it's rooted, if it's not rooted, 100% sure you can not change it. But I do not know the setting to change it. – Najera

Also, if you don't do the above, some partitions will be protected and you will not be able to flash those, so you might actually end up with an unstable device. – Najera

That's the bad news for me because my phone is in boot loop and my OEM settings are locked. I have heated the phone to get started with developer options but unable to bypass boot loop, is there any way i can boot my phone so that i can enable the OEM lock and update img. – Noway
