[LG G Pad X 8.0 ROMs, Kernels, Recoveries, & Other ] KittenSauce:
As I mentioned before in this thread, I haven't been able to get the cellular data working. Now I have a logcat of what happens when I try to search for network operators. I'm on the latest nightly (March 4, 2018) with the v52120m modem. The Wi-Fi network I am connected to is called "WIFICAEFFE-5G".

I can't make heads or tails of this log myself; hopefully someone else can. I also have Magisk installed, but as stated in my previous post, I don't believe that's relevant.
