I know why you loose 4G I worked with it with C spire for days. its the ICCID on Cspires end. some how installing sprint rom and not using APN backup app it gets scrambled. It took level 3 tech to see it. 5 minutes after seeing the problem I had 4G on sprint rom and I can use Google Wallet.

To keep this from happening to me again I always restore factory backup then dial *228 wait a few then flash new sprint rom and do APN restore from app. Be flawless since. Right now I have been using SynergyROM r443 for 2 weeks with only issue is stock sms will not split for 160.
