I recently acquired a used Epic 4g Touch on Craigslist and am anxious to upgrade it to a ROM based on Android 4.2 or above (to be more consistent with my wife's 4.3 Galaxy Nexus and 4.2 tablet). My stock ROM is currently Android 4.1.2. I experimented with several, but have not been able to connect to WiFi or access 3g with any of them. I would love to here from other Epic 4g Touch owners who are running custom ROMs with WiFi and mobile data capability. In the meantime, I've rooted my stock ROM and added the Agat Recovery. BTW, I'm on RingPlus's free plan which is great!
