I also cannot get an ext partition recognized in this ROM for apps/data2sd usage, is there anything specific requited for it to work properly? I fresh flashed the build with a newly formatted 16gb Sandisk, 1gb ext, no swap, partitioned through xionia, couldn't recognize the ext partition after selecting apps2sd in performance and rebooting, nor could it then enable data2sd to attempt that. Formatted the memory card through windows and partitioned an EXT 4 partition with minitool PW and it could not even recognize the SD after a reboot, had to repartition through xionia in order to recognize the card again, and then had to format again once fully booted up, now of course with the ability to activate apps/data2sd greyed out and unselectable.
I hope I have been clear enough for you to have an idea of what I did wrong or an alternative route I should follow, maybe I missed something or am using the wrong recovery or need specific class of SD card (mine is 4), please let me know if you have any ideas on how to help, it would be most appreciated.
