Can't unlock the bootloader

jimmyy

Hi guys, when I go into fastboot/bootloader mode from the recovery and I try "fastboot oem unlock" it tells me to press volume up, but when I press volume up, nothing happens. Only the power key does anything, which makes it exit fastboot. Would love some help on how to fix this or another to unlock the bootloader

Hi,
1. To be able to unlock the bootloader, first you have to enable OEM unlocking in the developer options.

2. It's pointless to unlock the bootloader (not needed for rooting or installing any kind of custom ROM) but by doing that, you have a great chance to brick your phone. Highly not recommended.

Sorry, used to nexus phones. I figured out I had the wrong drivers with SP flash tool so it wasnt working, however when I flash the latest superuser through TWRP it gets stuck on the umidigi logo when I boot. I'm not sure if you guys support helping this kind of stuff or not but it would be really helpful if you could help me figure this out.

Don't wipe the dalvik/cache in TWRP.

Hi
I already tried to follow that guide and I managed to flash the twrp (spflash tool showed me the green seen) but I can't start the recovery because it don't boot or I get the "no command" error. I also tried the adb commands in order to boot in recovery mode but I had the same results that I have using the power button+volume up button. I don't know how to solve this.

But did you swap recovery files to original, correct ROM before flashing your device???

Hi thanks for your reply
Anyway I tried multiple time to flash the recovery with different ROMs but I get the same results, I also tried to flash the original recovery and then flash the custom one but it didn't work too.
