I got my OGP Home and rooted it quickly and easily and flashed Slimkat 4.2.2. I had constant issues with dropping and losing signal. Convinced that it was an issue with KitKat, I flashed Vanir 4.2.1 and the modem that was suggested. This resulted in me COMPLETELY losing mobile data.
I called AT&T and they worked fixed some IMEI issues that I had, but it still didn't fix my mobile data. I decided that I would just restore from backup to the original Slimkat that at least worked most of the time.
I flashed back to slimkat and had no signal issues (so I am assuming that whatever the AT&T rep did to my account fixed the issue to slimkat)
I took the opportunity to reflash Vanir, and lost data services again. So I restored yet another time to slimkat, and my data worked again.
After all this I was so digusted that I unrooted and flashed back to stock last night and updated the firmware and broke the ability to re-root for now.
I like this phone, but I am considering switching back to Samsung.
Does anyone know what could have caused all of these issues with LG. Is this a common issue?
