Hi. After rooting my moto e xt1021 I flashed cyanogenmod. That resulted in a bootloop. So, via TWRP, I restored my phone to before it was rooted. However, I soon noticed that instead of saying Sainsburys, it now said no service. I then decided to try searching for networks by going into settings, more, mobile networks, network operators. Once there, it displays no operators. Then, when I press search for network, it says "Error while searching for networks. When trying to make a call it just says "to make a call, please turn off aeroplane mode." Does anyone else have this problem or know how to fix this.
