So with the AMAZING help of awesome xda member dr87
, I created a patched KK modem. This modem file is the KK modem patched to use the 10d radio.
This is for d800 only.
I just created it tonight and flashed it. All sensors seem to be working and I have service. Only time will tell if this fixes the SMS issue. The baseband in my software menu did downgrade to the 10d version.
If anyone else wants to try, flash at your own risk. If this solves my problem I'll probably toss up a threat in the d800 forum.
For links, go to the thread below.
(For people unfamiliar with Google Drive, click the download button at the top to download the flashable zip.)
