I have a Lenovo a820 and I was having issues with the bluetooth so I tried to run a factory reset. It seems to be frozen now on the startup screen but I can access the android menu. I had backed it up prior to doing the reset but it wont seem to recognise the files and restore it to backup.
I think I have to completely overwrite the system and upload jellybean but from doing a bit of research, I need to have the jellybean application as a zip and I cant seem to find a zip with it anywhere.
Any help would be most appreciated. I don't know a whole lot about android but I would have good working knowledge of the technical side of windows and OS and do a lot of maintenance myself as long as the instructions are clear!
