I decided to root her phone tonight and boy was that a mistake. I used the Revolutionary method and got root. Then I tried applying the official 2.3.4 ROm from Chinese Telcomm. As soon as I did, the "Verizone Wireless" in my notification bar and everywhere else changed to "Preferred System" and I no longer have any 3G access. Only wifi is working.
I immediately restored the backup I made prior to flashing that ROm and had the same exact issue. I thought about unrooting but I can't get ADB to work .
Does anyone have any idea how I can fix this? Please, I am desperate!
