[One (M8) Android Development] BSOD2600:
Been using this ROM for a few weeks with no problems. Then H12 downloaded and about the same time the radio no longer is able to get LTE -- only 3G. Tried reflashing H11 over itself, no change. Cleared cache/dalvik, no change. Reflashed MM firmware (dottat - m8MfirmwareTWRP3_0_0_1.zip - http://xdaforums.com/verizon-htc-one-m8/development/stock-m-firmware-nand-recovery-t3330972), no change. Tried changing the 'preferred network type', no change. Always stuck on 3G.

Pulled logs and noticed the following in modem log. Looking in ServiceState.java, RIL_RADIO_TECHNOLOGY_EHRPD = 13 so now makes sense why stuck on CDMA (EHRPD). Still not sure though why there are errors in CdmaLteSST, unless its something to do with GPE and adding unofficial CDMA support?

Besides a complete wipe and reload, what else can I try?
