[Q] No network or service after flashing HyperDrive Rom
I have a SGH-I747 AT&T version, I unlocked it using the built in menus. I upgraded rom on there from the stock to HyperDrive, I am on Tmobile network.
After upgrading, I noticed the MEID was all 0's so I followed a guide on how to restore it using NV-items_reader_writer.exe by generating using another tool and then writing the information from a text file to phone. After that, the MEID got repopulated but I am still having no network.
My phone was working perfectly fine till putting this rom in, I did backups with ROM Manager but then flashed TWRP recovery and can't access the nandroid backups from ROM Manager.
What can I do next to get my calls/texting working again?
