[Q] Stuck at Samsung splash screen - Need to backup data
The phone was working fine until the battery was empty. I tried to charge it and turn it on, but it's stuck at the Samsung logo splash screen. Holding the power button only restarts the device, so to turn it off I'll have to take the battery out. I don't know how to fix this, and if a factory reset is the only option, I need to backup my data first which I currently don't know how to either (without accessing the OS).
I've got to the Android System Recovery 3e menu and tried clearing cache, which did not help. The option to do a factory reset is also there, but I need to backup my data first, and I don't even know if this will fix the problem.
I'm also able to enter download mode.
When connected to my PC it detects an unknown device named 'samsung_android", and it shows up in adb. I've tried doing a backup through adb, but it wanted me to unlock the screen to accept the backup, which I could not, because I'm stuck at the splash screen.
Is there anything I can do to save my data? Anything through adb? Install root (never done this before)?
