I got a used T-Mobile Galaxy S Blaze(SGH-T769) from Goodwill. Since it still has information on it, I am attempting to factory reset it. However, whenever I try to boot it into recovery mode, it boots into a strange screen where random bars of color show up. When I boot normally, everything works fine but it has a lockscreen so I can't do anything normally. Besides that, its rather difficult to do anything since the phone is missing its power button.

What could be the reasons for the strange behavior in recovery mode? Are there any ways to factory reset it besides that? Should I just give up on the phone?

UPDATE: I bricked it... Phone won't turn on at all after following guide at https://forum.xda-developers.com/showthread.php?t=1591598, I forgot to uncheck re-partition... even more hopeless?

What button combination are u using and there should be a factory reset in the setting

Go to settings Scroll to backup and restore click it scroll down and there should be a factory reset button I'll probably have to have 30% or more battery to do so

  • Also make sure that the firmware is that right one for ur phone and ur service provider or u can brick your phone and it has to be the current firmware or newer because the bootloader won't let u if it's older at least I read that any way I've never tried to downgrade firmware
