So a few days ago my mum brought home a "Lenovo 2 tab a7-30f" tablet. She found it in front of a neighbours house with a sign that said "free tablet, still working". She gave it to me and asked me if I could get it to work and I quickly discovered the reason why it was given away: When you turn it on you immediately get blasted with error codes, most prominently "com.google.process.gapps has stopped". Most of the apps like chrome/youtube don't function either, and I frequently get popups that read something like "Application X has stopped." I did a hard reset but nothing changed. I also tried installing a rom of the android version (4.4.2) of the tablet using adb sideload, but all adb commands result in an "error:closed" (Also I have no idea whether that was the "correct" way to do it, so please correct me if that was a wrong thing to do). I don't really know what to do now, so if somebody can help me here I would really appreciate it There is no data to be lost by the way, so I dont really care if the solution would erase everything. Thanks in advance!
