a car drove over my mi a1 so i had to repair it, and after i replaced the screen and the body, i turned it on and it says:Your device software cant be checked for corruption. please lock the bootloader. i was wondering because this screen never showed up. so i locked the bootloader, and after the bootscreen, my device turned off. so i unlocked it and the screen showed up. i tried to boot in twrp via fastboot, but when i boot into it, the screen turns black. is it a hardware or a software problem?
(sry for my bad english im from germany lmao)
