Yesterday I upgraded my Neo X7 to the latest firmware. During the update I got the massage: Battery charge too low to execute the upgrade. My Neo was, of course, connected to the powersocket. Somehow, something happened. The device was stuck, black screen. After 15 minutes the X7 could be used again but now is VERY slow, playstore does not work anymore, from many apps I get the message they need to be updated which I can not do because playstore is not working. When I check the description of the device it says it has been updated to the latest firmware but the specifications say differently. What to do? Will a reset to factory settings work?
