Go to s-off.

Flash firmware for JB ( hboot, etc )
https://www.dropbox.com/s/4fgu7hs7ch...mware.zip?dl=0 ( rename to 0P4EIMG.zip and copy on sdcard, then run bootloader. This downgrade you hboot etc. )

flash recovery for jelly bean,
https://www.dropbox.com/s/a9ojea649b...modry.img?dl=0

flash stock rom for zara UL ( mount system and delete with file manager in recovery file /system/bin/hcheck )
https://www.dropbox.com/s/205a9uuoli...401.8.zip?dl=0

remove tampered text ( skip point 9. Lock bootloader fastboot oem lock )

lock bootloader
http://forum.xda-developers.com/show....php?t=2475914

and remove s-off with command fastboot oem writesecureflag 3

And warranty continues

Tested and working
