Hello to everyone,

First of all i bought this phone with Flyme version 7.0.0.0G  and i had some issues with it and i wanted to update flyme. but here is another problem, i can not do this. firstly it told that the FILE IS CORRUPTED and i tried more variants to do this update but every time it was telling me that the file is corrupted. how so?

and someone wrote how he solved this problem on his phone, by installing Flyme version  6.7.10.31A beta and then he updated to 7.1.0.0G and it worked to his phone. So I tried the same and i still can not update to a newer version. can someone please help me?
