I have a Samsung Galaxy S2 d710 from Virgin Mobile, and I flashed it with all the info from my old sprint phone to use on Ting. I finally (after 15+ hours -_-) got it to work on Ting acting as my old crappy phone. I had flash back to a sprint rom because I could not connect with a modem connection (for dfs cdma tool thing) on cyanogenmod. After I got it to work, I promptly flashed back to cyanogen and pulled from a backup that I had made earlier. Boom. It seems like all the crucial pieces needed to make my phone connect to the network were erased.
Then I decided to flash back to the sprint rom. After spending another few hours (I kept having small problems and ended up calling technical support for some stuff) I got it working again. It is nice, I can text and call perfectly fine (haven't been able to try data yet) but I hate the stock roms with a passion. I NEED cyanogenmod back.
If anyone knows how to flash back without disrupting my frankenphone service, please help! Or, if you have info on how to fix it once it is flashed, that would also be sweet. Any help is veeeeeeery much appreciated!
