I replaced the memory, the old one was not read, after the replacement I updated the firmware. The device hangs on the screen saver and reboots. In the fastboot mode OEM can not unlock. In the MediaTek PreLoader (BL) mode, the OEM unlock is not active. I need an unlocked bootloader to write TWRP and update it on custom. Or tell me how to unlock the bootloader if the device does not turn on?
