aiduxxx · May 31, 2012

jonny68 · May 31, 2012

+1 getting mine this weekend and it's been confirmed that it will be locked to 3 Ireland and im with Tesco Mobile, can someone please post unlocking codes or method as soon as it becomes available otherwise i wont be able to use my phone.

Perhaps the mods can make this a sticky as well no doubt there are many people looking to get it unlocked.

Galaxy S unlock from the Play store works on SGS1 & SGS2. Not sure if it works on the S3 though.

If you want to try it I suggest you root first then backup your efs folder in case you lose your imei. Worth a try I think.

Thanks mate but id sooner not risk it in case, i recall shortly after the Galaxy S2 was released i think it was Chainfire posted a program or app which could unlock the phone and worked a treat and was for free,hopefully someone else can do similar ASAP.

If your phone is rooted PM me a link to your nv_data.bin and I will take a look, initial analysis of the GT-I9300 nv_data.bin indicates a possible simlock block sign, but I cannot be sure without more files as an example.

Thanks to Zanr Zij who supplied his nv_data.bin file to me first.

My first ever Samsung handset, I don't have a different operator SIM to check if my handset is simlocked, is there a code i can tap into SGS3 to find this out?

Many thanks!

I though one of the main advantages of the international phone was that it came unlocked. Am I missing something?

If you buy directly from a network, there's a chance the phone will be locked to them. Sim-free ones are obviously unlocked.

well got mine through yesterday, i used phones 4 u to upgrade and using the code in a previous post shows there is no locks what so ever on my handset

If Odia can't unlock it, no one can!
He did brilliant job with SGS2.

Fingers crossed!

I received my S3 on theTthree network earlier today.

It has a 3 boot up logo but is not sim locked at all.

I have tested with Orange and O2 sims and both work perfectly.

What country is that mate?

I've never been with 3 but some people are saying that their phones are always locked whereas others are saying they are not but it would be useful to have unlocking codes that work, im reluctant to purchase before then as i don't wanna have to spend €20/30 to unlock.

Not very well at the moment since no one has provided their nv_data.bin files, note this offer is open to anyone and the phone does not have to be locked to help.

Hello Odia,

I sent you the files you asked. Please let me know if you need anything else. I would be really pleased to unlock my phone

Odia · May 31, 2012

Thanks guys.

Well its as I suspected from the file provided by Zanr Zij, there is a 256 bytes sign after the second simlock block, only I am not sure what its signing at the moment, so I need a before and after unlock by code nv_data.bin file or someone with a locked phone who will allow me to try somethings out over TeamViewer, I will take the required backups, but cannot guarantee the phone will not be corrupted.

jonny68 · May 31, 2012

Haven't yet purchased the phone yet so afraid cant be of any assistance but im keeping a close eye on this thread as soon as there is a successful unlocking code ill purchase.
