Hello, just upgraded from a Galaxy S4 on T-Mobile to an unlocked Verizon HTC One M8 handset. Popped in the sim, I can send and receive text, but no data, get the usual "sim unknown source" stuff. I am wanting to flash either LolliGPE or Skydragon.

My question, is there anything special I need to do before/after I flash these, since I'm using a different network than what the handset was originally supposed to be on? Maybe I need to flash different radio? This is my first time using an unlocked phone, previously all my phones with custom ROMs were on the same network as the handset variant.

Otherwise, would I just update to the latest OTA update from Verizon, root, install TWRP, then flash LolliGPE, and I'm all good?

Thanks for the help
