Hi. I recently rooted and flashed my phone, but since doing so I've been able to get 4G/LTE to work for me. At first I thought it was just the initial rom i flashed, but every single one I've tried since has failed to work. I restored my backup of the the original rom (backed up immediately after post-root), but that has not worked either.
I should add that a couple of the roms I tried, upon initial setup for the first time ask me to wait a few minutes to activate mobile data. While the 3G signal works and appears, the waiting goes on indefinitely until i skip it. Data still works but 4G/LTE never happens for me.
Any advice? Thank you
