I have an Acer Iconia A1 tablet. My problem is that first the software was freezing when i was opening any browser. Then the issue got bigger and the tablet was freezing right aftee booting. I made a factory reset/ wipe data and after finishing this process it entered in a boot loop. After 15-20 minutes i decided to make another factory reset and now is showing for more than two hours that little robot which appears when installing software. Can You help?
