oooh so their is some special things to set up. is this the ftf i need? [NEO L] All Stock Firmware .ftf , and also can i even flash foreign ftf's on my play?
1 Flash turbo 3.1 kernel (note: you can use also lupus JBv8 480p)
2 Go to recovery and flash CM11 ROM
3 Switch off your phone
4 Flash the CM11 kernel with charging fixed
it should work for neoL and play, no need to flash neol firmwares as they have to flash our xperia play firmware...
ps: as you have r800x you dont need FTF 79 cause your phone have vendor partition already unlocked..but with this rom you probably wont get phone signal on CDMA..
