u got the options in the first try? i changed android version and only get the 'sdcard' folders, like photos, movies, etc.
ye, rooted and installed twrp, already done this.
i'm in the pro version, but cant access /factory, there are only 2 checkboxes to switch and only can check emulated sdcard, the buttons below, recovery, back, next, etc... no other options, no options section or anything :S
it seems i'll need to pay a boxer to get my proper IMEI and never touch the phone in this manner way again.
Umh, I tried hexamob and it shows me /factory so I think that you are doing something wrong or your partitions are really messed.
Try this, wipe system, data and cache, flash last cm11 and askp kernel (just because I tried with this kernel) and try again.
Let me know, good luck
