Unlocking Samsung s3 i9300
I have a Samsung s3 i9300 on h3g.
It was on 4.2.1 and I have downgraded to 4.1.1. and now rooted.
I have tried: Vodoo Galaxy s3 unlock which does not work and also the *#197328640# although I am on 4.1.1. I do not have a UMTS option.
I have put another networks sim in and tried all methods with both sim cards.
I have also tried Valhalla and this does to option 3 and wont do the final option and I have also tried the md5 fix with no success!
Any further ideas will be appreciated. I have tried searching thoroughly but all previous posts seem to say try all the above (and I have!)
