Hi guys. Sorry for writing in english here, but I've got a a problem downgrading to MM.
I own a Huawei P9 Lite VNS-L21 Europe. I've done everything like explained but when I'm trying to install the rom via dload method, it stops at 17% and after ~10 min it says "Failed to check the update package. Please downlaod the package again".
I've used the update package for VNS-L31.
When I use the package for VNS-L21, it says "Incompatibility with current version. Please downlaod the correct update package".
What can I do? The problem is that I've accidentally formatted the /systme and the /data partition.
