But it really don't work... Your ROMs with -swap and grtsarav last build with -swap make a job. change_fstab.zip does nothing...
Ok, booted in TWRP, wiped, installed this 4.4 PAC ROM, flashed change_fstab.zip. Run command in recovery terminal, pulled /tmp. Everything without reboot.
Hey, the freshly pulled fstab.n1 is changed!
"# internal sdcard (:4 means 179:4 inode)
As it should be after swap. Booted to the PAC ROM, looked at fstab.n1 - it's reverted to default, and internal sd is 4 gb. So the trouble is with bootloader?
I attached newboot.img. If you need some other files from /tmp pull, let me know.
