If I force a downgrade via sideload in recovery, do I risk losing my other data?8.4 Update killed all reception to network for me. I went into the *#*#INFO#*#* menu and tried changing around preferred network to no avail. Tried making a t-mobile apn but that didn't work either. Help!
Edit: All info on my sim looks correct and normal too. Wifi and everything else works fine, just zero network/cell service.
Update: downgrade didn't bring back reception. MSM'ing back to start. Dammit. T-Mobile users beware this update!
