I didn't downgraded it ,I bought it on this firmware .but I installed GMS also I tried hard reset but not update at al
I have no idea because it is not google that blocks when you reset the phone without gms it offers you updates? Do you have a huawei account?
Ah Have you tried to update with a vpn?Yes and i asked the service center in my country ,it said that they cannot support the device because it is not deployed to my country
Do you know from where can I get firmware for region c185 as I searched a lot but didn't find and on pe that found was 10.0.1.33 which is earlier to my one
