Okay, so the first thing i did was mount my microSD(external sd) then a full wipe. Even though i was mounted to my sd card, i still had to navigate to my internal memory to select the zips i wanted to flash. I first installed an older release of Hyperdrive Rom, and during installation, i selected Full Wipe option again. i also added my AT&T compatibility pack.zip to be flashed right after the ROM. Also, i dont know if this affected anything, but i tried installing the T-Mobile compatibility pack on a previous attempt. I read somewhere where some1 did this and it worked for them, but it didnt work for me until i did another install of RLS15 and the ATT pack.
Hope this can help you
