How do i back up my EFS or IMEI on NExus 4? I searched google but there are basically no topics on this.
The only topics i found said that you don't need to back up EFS/IMEI on Nexus 4 since it's only really for samsung phones and google phones don't have EFS folders?
IS this true?
if so then how come there is a way to back up EFS for NEXUS 5 and not for nexus 4?
