Google Play and downgrade

Hello. Updated phone to 4.5.7a Soft but I do not like and want to do the downgrade, made from 4.5.7a> 4.5.6a and wants to below but with all other Soft is a mistake I tried 4.5.6i, 4.5.5a, 4.5.4a, 4.5 .3a what to do? I want to have soft

I have a problem with Google Play, after installing google installer gives me an error RPC-7 AEC-7 how to fix it?


@Bartek-Wytracz Did you clear the data, while downgrading from Lollipop to KitKat? This would have been required.

I had the same problem. You need to clear data for google play and google play services, restart your phone and open googleplay, make sure you agree to their terms and it should be fine.

I am also want to downgrade my meizu m1 note from 4.5.6i .Official version doesn’t work properly. Plz help


@muniphs did you read the changelog of your firmware? If not, do so.

There is something written in BOLD right in the first line for the header.

I didn’t check it what was that


@muniphs so do it now! either go to the firmware section of use the search function.

Now i can’t see those. It shows only like this S51105-163854.jpg


@muniphs That’s why I just suggested to go to the Firmare Section of this forum or use the search function of this forum.
My last commend on this, no need to waste more time. If you have a different question feel free to ask.
