So I have an Acer Acer B3-A30 tablet, which is stuck on the Acer logo. I'm trying to unlock it's bootloader (with fastboot mode), so I can reflash it (with a stock rom), but it just shows an error saying "Failed to unlock bootloader." I've checked both of the commands fastboot oem unlock and fastboot flashing unlock, but they just don't want to work. I haven't installed root or any system modifications, this is my first time ever doing so. It would be even better, if someone told me how to fix it without bootloader unlocking and these other stuff.

  • fastboot flashing get_unlock_ability = 1?

  • @alecxs "you need to enable usb-debugging via Settings/About phone/Version, Tap 7x on build number Go to Settings/Additional settings/Developer options, enable "OEM unlock" and "USB Debugging" " I can't boot the device to enable those.
