[Q] Need help unlocking S3 on 4.3 topic

Hi xda

I have referred to this site many times for help but never became a member until now - I seriously need some help!

I recently bought a second hand S3 LTE which I knew was locked but as I had unlocked a few phones in the past I thought it wouldn't be a problem... until I encountered Android 4.3 and its bodyguard Knox. Searching on forums I found many other people experiencing similar problems but nothing conclusive that didn't involve using a Z3X box which costs about as much as I paid for the phone.

Apologies if this has already been covered in some form in another thread but I have done a lot of searching and a lot of hair pulling before coming to this stage.

So to cut a long story short I managed to successfully root the phone using CF through Odin and installed the version of SuperSU capable of bypassing it (downloaded .apk as opposed to play store which some people had said worked).

Next stage was to remove Knox, I installed NoBloat Free as suggested by someone in another forum and I basically removed anything with the word Knox in it and that seems to have done the job.

Now I just need to unlock the damn thing! While I have had some experience with rooting / unlocking a few android phones etc I really don't have much knowledge on the subject and pretty much forget it all in between phones :silly:

For the record I don't care about warranty, flags etc and am more than happy to downgrade if it means getting the phone working.

Any help would be greatly appreciated!
