3 - Waiting untill it boot . . .
- Done phone booted .
IMPORTANT :
- 98% nearly of phh gsi will boot .
- 1 % roms like extended ui :-
with it do all steps like before but
Code:
1 - Don't install magisk .
2 - Wait until u get bootanimation .
3 - Force reboot .
4 - Reboot recovery
5 - Install magisk .
6 - Reboot system and it will boot .
Q : WHY ??
A :
A - Installing magisk before bootanimation will Force phone to go in bootloop .
B - If u won't Install magisk when u see bootanimation , phone won't be able to boot and phone will stuck on boot animation .
- 1 % roms like aosip and viper os , that roms has issue in itself .
