While running CyanogenMod on a CDMA device has many advantages, one glaring disadvantage is the ability to update your PRL (Preferred Roaming List) or data profile, which are only available via stock ROMs. Often times if you need to run a GPS fix or update your PRL, you need to backup your CM9 install, restore to a previous stock ROM, do the ROM dance, run the desired process, dance a jig, restore to CM9 install, and hope for the best. Well now you don’t, thanks to the Epic Touch CM team.
The Epic Touch CM team has put together a nice temporary ROM which boots the FF18 stock firmware from the /EMMC partition on the Samsung Epic 4G Touch without changing your current ROM. This temporary ROM allows you to do the following, and more:
- Update Profile
- Update PRL
- Sprint Activation
- Dial codes and diagnostic mode
