B522 is for European region, but your phone was not European, CLICK HERE to see guide, follow it and change region to Europe and then reinstall B522
Should this work on mate7 that has never been upgraded to 6.0? I’ve only had 5.1.1 and I have been unable to upgrade it using ota.
As I am stuck on Huawei logo on B511 beta install
Yes it works, follow guide carefully
