How do I fully backup my device (let's say "snapshot") in order to easily restore all apps, wallpapers, settings, etc (possibly accounts too) when it returns? I can easily backup programs, but I don't know about their data. I also have a Bitcoin wallet there, so I need to back my private keys up in order to receive coins at the same address later.
How do I un-root and downgrade the firmware to Acer's original stock 3.0? When I updated Recovery I did a backup, so I believe the final step is to restore that backup.
By the way, does Acer consider rooting a warranty breach for hardware problems? I know many manufacturers don't care if you change their firmware when you send them a device with clear hardware problems, but they eventually restore everything to stock.
