Some time last week the phone stopped booting. It would get to a Nokia screen and hang for hours. I managed to get into recovery and attempted a factory reset, but it hangs on 'wiping /data'. Now it can't get past the Android One screen.
I never unlocked the bootloader or set up USB debugging and I really wish I did. I use linux at home and it won't recognize the phone using adb or fastboot. I set up an older laptop running windows with nokia USB drivers, adb, and fastboot and the laptop can't see the phone either.
I was thinking of trying to re-install firmware from sd card, but don't know where to get it from. Is there a reliable source? Should I install a custom recovery first, like twrp, or is that not going to work since the bootloader is probably locked?
Any help would be great. Thanks!
