I tried to install a 2.1 ROM (I was running a 2.1 rooted ROM already). When I rebooted I was greeted with the activation screen. This seemed normal. However, when I try activate the phone the prompt says that it is attempting to gather information, and then eventually says it can not activate my phone. I tried it about 100 times with different signal strengths. I tried a restoration to the backup from before installing the ROM and when I rebooted I was brought to the activation screen again. The phone looks like it has all my apps installed, the settings are right, and everything looks good, but I can't use it because I need to activate, but I still can't process the activation. I rebooted again to SP Recovery and did a full system wipe and then tried installing an even older backup, and everything looks good, but I have to activate, and it wont go through. What else can I do?
