If you don't wanna use EMMA or flash latest .228 image, you can flash oem from recovery. use https://github.com/anestisb/android-simg2img tool to convert SW...img to ext4 image and then setup 500mb tmpfs on X from recovery, use netcat to move the image to the phone, and then dd if=new-converted-oem.img of=/dev/mmcblk0p28 bs=512
