Ok no problem here is a quick guide but please read and understand what you are doing first look here for some guides to help you >> <<

(1) Download Odin and Samsung drivers (please read guides on how to use)
(2) Root your phone ( use CF-Root >> <<
(3) Place the patched files on ext sd card and use cwm to flash the patched modem and kernel ( cwm is included in CF-Root) if not you can download and install it with Odin
(4) Reboot you should then have a signal.

If you get a bootloop in any of the stages above reboot to recovery and factory reset/wipe cache

Please note the above is a quick guide please read all the guides and be sure you understand them before doing anything.

As for which files to flash you can use any patched kernel and modem but I would probably use the and the

Good luck and be careful.

So if we don't have an EFS v1 backup it's possible to unlock I9300 for free?
