acer z120 stuck to logo screen
I have an Acer Liquid Z120
It was running fine until it stuck to the logo screen and it is like that since then.
I was googleing and i tried to wipe/factory reset, but i still have the logo screen and it doesn't pass it, like in the videos.
I've downloaded the acer z120 single sim official OS from the acer website, and applied update from sd card in recovery mode, it runs untill 50% and after that it says "installation aborted".
What to do?
It was not rooted, it had jb 4.1.
