Hello Guys,

I've a huawei P9, i updated from EMUI 4.1 to 5 but i noticed that the system is quite laggy. then i unlocked the bootloader and installed a twrp via fastboot to install a costum ROM. but when i tried to boot / enter fastboot or recovery mode it just got stuck showing the error message your device has been unlocked and can't be trusted. it's not even recognized on pc
Please help !
