- Reboot into recovery
- Make a backup of course
- Flash TWRP 2.7 and reboot recovery
- Flash the 24A OTA bootstack from XDABBEB's VS98024A ROM and reboot recovery
- Wipe system, cache, dalvik
- Flash JackpotClavin's OTA-based CM11 over my current install and reboot
I realize a dirty flash in this way may introduce its own set of problems, but I'm willing to take the chance if it means I can go straight from my current CM11 install to JPC's without having to wipe everything and go back to stock first.
I'm very comfortable with the command line and I have a good knowledge of how most Android devices work (bootloader, radio, recovery, kernel, cache, system, and data, and how they all tie together, all that necessary info). I just don't really know much about all the extra stuff for the G2 and I haven't had time to research it, so I've got no clue if flashing the bootstack is all I need, or if I'll also have to go hunting for a 4.4.2 radio zip to get the baseband up to date or anything else.
