My phone soft-bricked two days back after it showed an error while updating its System and I got it repaired later. Now again I’m getting an system update notification. Should I accept the update or never update my phone! Because I don’t want to risk another brick again.
Charge the phone first and try the system update again. Shouldn’t brick this time. If it does you probably know that you need to flash the RUU firmware or factory reset.
