I have a rooted DX with 2.1 and it will not alow any custom roms to be installed... There is an OTA for 2.3.15 but will not update for some reason. I have read a great deal through these forums but still not sure what my next move should be. I do not know what an .sbf is or where I can find one if thats the road I need to travel... At this point I'm wondering if I should get back to how the factory had the phone and then try the 2.3.15 update, and then root? Any suggestions?
