The method posted for unlocking S3 on 4.1.1 doesn't work on 4.3 OTA update. Downgrading to 4.1.1 is not possible as it will brick your phone.

Is there anyway to unlock AT&T 4.3 Galaxy S3?

Does anyone know if a phone will remain unlocked if it is already unlocked when upgrading to OTA 4.3?

Anyone has a solution for this? I really need this for a trip and I think a lot of people will run to this problem.

Thanks. Despite my better judgment I tried Cell Unlocker and they provided a code that didn't work (on original 4.3 ROM and SlimBean ROM, provided them with the video, and screenshots, etc). I'm trying to get my $30 buck back. (stupid I know but I was desparate). Wish I had known about sammobile.
Anyway I tried the code they provided I'm worried I'd spend more money and the code won't work again and it will freeze my phone (how many tries do I have?).

Could you please tell me what is the Qualcomm NV Tools doing and how will that help unlock the phone? Also these are for GT-I9305. The *#7284# code didn't work so I'm worried the rest of the instructions won't work for now.

For anyone reading this, the cellunlcoker.net service failed to unlock my 4.3 OTA and has so far not refunded my purchase so beware.

Just something I read from one of the links here. ★ ☆ ✰Sticky Roll-Up A Guide To All Guides and Q&A's ✰ ☆ ★

There's Imei and what not that you need to backup before doing anything if you have not already.. Once you lose that its a rough go.. Sorry I'm not sure why you would have to unlock your phone. I think the root process and everything handles that. All your questions should be answered within that thread.

Thanks. I will have a look at those. My phone is already rooted. That, however, doesn't unlock the phone. The reason I want to unlock my phone is that I want to travel internationally and I want to be able to use my phone with sim cards from carriers abroad. I called AT&T and they refused to unlock it even though I have few months left on my contract.
