Any way to get around this?
For the time being, I've flashed ExpertV4 rom which is Android 4.4.2 and it works fine in terms of the network operator.
I've used TWRP to change from FusionX rom to Slimkat on my Huawei Y300. The Slimkat seems to be working fine but can't connect to hte network. When I go into mobile networks, I get this message when I try to connect "your sim card does not allow for a connection to this network" and error searching for network operators. So it's stuck on emergency calls only.
