Using AT&T sim on blacklisted T-mobile GS III

Hey guys,
I got scammed on craigslist and the guy won't respond. So I bought a T-mobile Galaxy S3 and it worked fine for over a week until 2 days ago when it stopped connecting or registering to the T-mobile network. I found out from T-mobile it was blacklisted as stolen/lost that day. I called to confirm the phone wasn't stolen or lost when I bought it. The T-mobile store says there is nothing they can do except offer me a new phone from the store to pay full price.
Can I unlock a phone marked as stolen/lost using an unlock code and use it on AT&T?
I tried searching the forum and I found a thread about a guy who already had the phone unlocked so he was able to use it on AT&T but in my case, the phone is not unlocked yet but is blocked from T-mobile networks.
Thanks in advance,
Buzz

Well if you unlock it before the whole illegal thing starts you can use it on AT&T.

If I unlock my T-mobile phone, can I keep the T-mobile stock rom or do I need to flash it with the AT&T stock rom?

If you are on stock, why dont you just dial *#197328640# to go to phone control menu, then network lock and turn off the network lock. If you do a google search for unlock galaxy s3 xda forum u ll see it.

DON'T EVER FLASH AN AT&T ROM even if you switch carriers you will brick you phone, only flash rooms from these forums

No. You can flash at&t roms on the T-Mobile s3. Many including my self have done it many times. Same hardware.

1111+ Thats correct I have tried every rom out there from att and it worked on my tmobile s3. Now for the op. looks for the thread on general there is one that shows you how to unlock your phone without a code. It was meant to be for the note2 but it worked on all us s3's I have mine unlock that way put in my friends att sim and it worked fine only thing that the speed its a little slower not 2G though. And thats because att's 4g its 20ish not 42.
Any ways. If you were called tmobile and talk to a superviser they can change the IMEI number on their system and the phone would come back to work in 48 hours.
I know because It have happened to me too. It doesnt matter if you have your tmobile sim on it for at least a day tmobile computers will register that phone onto your network.
P.S the only thing that will changed from a ATT rom is that build.prop It will show that its an att rom but you can edit it to d2tmo with root explorer

Just don't flash other modems from other carriers that will Brick you.

Why would t-mobile change the meid if its black listed

FYI... Tmobile and att share blacklists... if its blacklisted on Tmobile it won't work on att either

Ask them to unblock the IMEI. I am the same situation except my phone is a warranty replacement from T-Mobile.

This Phone doesn't have warranty

Im gonna ask to unblock the imei, thanks for your advice

They most likely will not un-blacklist an IMEI for this reason, but sure, why not try.
If you're not super lucky you'd best just sell it for parts and be more careful next time.

Unlocking a sgn2 on O2 network (uk)

Hi folks.
I'm switching networks from O2 to talktalk (vodafone) and I'm wondering if anyone can direct me to a free method of doing this. I've watched the videos on youtube that allow it to be done by dialing “*#197328640#” on the phone but when I enter the network lock section it says "MENU NOT EXIST"
I'm guessing this is an O2 thing so can anyone help me find a way to get my device unlocked?
ps. Hope I have this in the correct section. I've also tried searching on here but no joy.
Thanks

GalaxSim worth the couple of bucks.

I think you have to downgrade to a 4.1.1 rom first, unlock your phone then flash a 4.1.2 rom.

I've tried using galaxsim but I'm getting
"unable to read NV data"
You guys are saying it's worth the money but the app appears to be free. I can't see a paid version only a free version.

It will ask you to buy if you want to use it to unlock.

Thanks for the reply's folks.
I downgraded to 4.1.1 to try using the *#197328640# method but that hasn't worked.
I've tried using the old version kdogguk posted but i'm getting invalid IEMI number now but it's saying my phone is unlocked
my phone is locked tho as it won't take my new talktalk sim.
My phone was stuck on boot screen when I downgraded and I had to root though odin then reset it before it would work so I think I've downgraded to the wrong firmware as it is now branded O2 firmware where as before even tho it was locked to O2 the firmware was neutral (not O2 branded).
I've rooted as I said but it won't install custom roms so I have a problem now. Going to upgrade to 4.1.2 but need to make sure I have the right firmware this time.
I'm having some time of it right now lol

This galaxysim app is now saying my phone is unlocked but it won't take my talktalk (vodafone) sim

Still no luck? My note 2 was on o2 first thing I done was root it, tried that code but didnt work then used galaxsim its free but said it could be done paying £2 something. Then I installed a standard btu rom. Funny thing is not tried diffe sim yet. Just hate locked phones
Where abouts in UK are you?
Sent from my GT-N7100 using xda app-developers app

on my phone it says my device is unlocked but when i try to call any number it says not registered on network, what's the problem?

turn off data. turn off mobile. turn them back on. reboot.

Galaxsim was saying my phone is unlocked but it wouldn't take my talktalk sim. I ended up paying £9 to get it unlocked on ebay. Working fine now.

Strange because my phone is O2 but I've been running it with a 3 sim from day one.
They should be unlocked by default.

There was a problem with the network

So I have this issue where intermittently I get the error "there was a problem with the network" in you tube or "no network" in Google playstore ".
If I hit RETRY twenty times or so, it comes to life.
This only happens on Sammy based roms but not the stock unrooted. All aokp and aosp roms are fine. So it's not the Network/reception.
Does anyone have this issue?

(Q) rooted sgs 3 tmobile data not working

I gave my sgs3 with to a relative working perfectly I was running wicked 10.1 rooted. I reinstalled the Rom and wiped everything so I would be like new rooted wicked 10.1 he upgraded his SIM card with tmobile and now data does not work. How can I get this working for him? What reason why data not work? I'm confident they gave him the right SIM card.

No idea tbh. First I've heard of a new SIM doing something like that. Maybe they gave him an old one by accident?
Best bet imo is to flash the firmware with Odin and factory reset again. Test while full stock. If its still giving problems then its prob a faulty sim.
Sent from my SGH-T999 using Tapatalk

They gave him a new SIM he didn't have a smart phone prior. He took the phone in to tmobile and they gave him a smart phone SIM.
