Just about to give up ..thought I would try this forum as as final effort..
I have 3 nexus 7 devices and love them..however my daughter’s has started going straight to ‘shutting down’ immediately after power up..I can see the battery indicator is showing full in the few seconds I have before thee unit goesd off.Also, if I connect my charger I can see the white battery icon indicating the unit is charging. I have tried factory reset and clear cache several times..both complete successfully.. However the unit still goesd off every single time after it poiwers up to the login screen..
After I press the power on button..I do sometimes see at brief flash of something on the screen jus prior to the coloured balls expanding and contracting.. Its so fast I can’t quite make it out..it looks like four icons ..one at each corner of a square.. Could this be something malicious.. Perhaps not..especially after a factory reset..
Is this unit Banjaxed..? Any help greatly appreciated..
