So I'm currently in Europe and I will be here for 2 more months and I would like to unlock my phone because $4.19 a minute is ridiculous. However tmobile support is being, let's say very smart. The first representative said "just visit you're nearest tmobile store and we'll help you out there." After I had already told them I was in a country without tmobile. So I was wondering if there was any way to do this for free? I really don't want to have to spend any more money right now. I'm currently running liquidsmooth lollipops latest build. And I really don't want to have to revert to stock because I currently have Internet speeds of 85kb/s and that would take ages to download and then reset up my phone. All help is greatly appreciated.

Which version should i downgrade to, and could you give me a like to a method of unlocking it?
Before flashing any TW ROMs via Odin, confirm the bootloader and modem on your phone.
I'm not sure but if the T999 is like the i747 (ATT s3 version), you cannot downgrade the bootloader from 4.3 to a lower version. Doing so may brick the phone.
If you are on a 4.1.1 or 4.1.2 bootloader, you should be able to downgrade to stock 4.1.1 and you may be able to unlock for free using this method: http://forum.xda-developers.com/showthread.php?t=2014982
If you cannot downgrade to stock 4.1.1, you'll need to buy an unlock code and enter it using a stock Samsung dialler.

I was recently laid off from my job, but still have the Note 2 I had paid for when I started. The company refuses to pay the ETF on the line, so AT&T won't unlock it to let me use the phone on Straight Talk. I'm looking at rooting it, rolling it back to an earlier version, and unlocking it that way, but I'm unclear as to how to do it.
I know I can root, flash a 4.1.1 stock rom and unlock it that way, but I've also seen posts saying all I need to do is flash an old modem. Which is it? And if I'm just flashing back to 4.1.1 to unlock it, is the best course of action to do a nandroid backup of my current state and flash that after unlocking? Everything should stay unlocked, right?
It's the J2 modem, which is the first released..

It's the modem you change because the service menu you dial is for the modem settings.
Yes that is correct. I did that with my buddy's Att GN2 and it worked.
How do I unlock the phone? I currently have Cm11 on it.
I want to ditch rogers (terrible service) so what do I need to do to unlock it?
side note, when I got the phone it was via future-shop warranty and they gave me a fido version and put my rogers sim in it, did they unlock it then?

Since Fido is really owned by Rogers, your Rogers SIM may work in the phone if it was originally locked to Fido. To check whether it's unlocked or not, try putting in a non-compatible SIM (like Bell or Telus) and see whether it prompts you for an unlock code. If it does, you would need to purchase a code online or request one from the carrier. If it wasn't on Android 4.3 prior to the CM11 installation, you may be able to install stock Android 4.1.1 and free unlock. Either way, whether you are free unlocking or using an unlock code, you have to be on a stock ROM for it work. You can check your phone's settings and see what baseband and bootloader versions you have. This will tell us know whether you should flash stock 4.1.1 or 4.3

Baseband is I747MVLUEMK5 bootloader I have no idea, I just used odin to flash CWM.
I'm open to flashing 4.1 to get a free unlock then going back to CM11

I747MVLUEMK5 is ver. 4.3 and you almost certainly have the 4.3 bootloader as well. With this, unfortunately, you can't downgrade to 4.1.1 where the free unlock option is available as any attempt to do this could brick your phone. You would need to request an unlock code from the carrier, if eligible, or purchase one online. There have been reports also that the unlock codes don't work when you are on a custom ROM so if you buy one online and it doesn't work, you will have to flash stock 4.3.

ok, which carrier would I have to talk to, it was a fido phone as mentioned previously. Also is their a possibility I could downgrade to 4.1, or is it a guaranteed brick?

You would need to contact Fido since it was originally on their network. I'm afraid nobody has yet posted a method to allow you successfully downgrade to 4.1.1 and still preserve the free unlock functionality. You could follow some instructions posted in this forum to downgrade to 4.1.1. However, this wouldn't allow you downgrade the bootloader/modem which is required for the unlock.

I found a way to downgrade from 4.3 to 4.1.1 or 4.0.4 stock. (for Bell).
I bought and used Mobile Odin (available on the play store). Anyhow, it flashes the stock rom and not the old bootloaders. Once you're on 4.1.1 or 4.0.4 the problem is that *#197328640# no longer works. Basically when you type that ServiceMode comes up, but all the options are gone. I believe this is because they locked those features on the new bootloader (which is still on the phone after the Mobile Odin downgrade...)
Unlocking this phone has become a major pain in the ass.

You are quite right. Sam and the networks are winning this time. You can indeed use Mobile Odin to downgrade the system (ROM). However, there hasn't been any reports of a successful downgrade of the bootloader. Therefore, even if you downgrade without bricking the phone, you can't free unlock. Tough but you will need a carrier unlock code.
Hiya,
I currently have a Samsung Galaxy S3 locked to Bell, and I have installed Cyanogenmod 11.
I'd like to unlock it and give it to a friend.
My questions are:
1. If I unlock this phone, will it work with Zoomer Mobile? It's a subsidiary of Rogers. I would imagine it would work, I just want to make sure.
2. I've read somewhere that Cyanogenmod causes problems with unlocking, is that true? Will I have to go back to stock firmware in order to unlock it, then go back to CM11?
3. I can't seem to find any information about unlocking through Cyanogenmod... anyone have a link to a guide of some sort?
Thanks in advance for any help!
am pretty sure you have to be on stock firmware to use free unlock method. will try to search around with for more info

Tell us the bootloader version on your phone.
Once unlocked, it will run on all carriers except wind and mobilicity.

Thanks, thats great to know! My bootloader version is I747MVLUEMK5.
Thanks for all the links mrrocketdog, looks like everything I need to start unlocking!
Since you are on the MK5 bootloader, you will have to flash back to stock, purchase an unlock code, unlock the phone, and flash back to your custom ROM.

Which version of stock, though? I can't remember what the phone came with since it was so long ago... I think it was something like 4.1 , but I'm not sure. Since I've since updated to 4.3/4.4, I'm also worried about bricking my device, because I've heard that flashing earlier roms with newer bootloaders can do that.
Which version of stock should I go with then? Thanks in advance!
Confirm that you have an i747m with mk5 bootloader and baseband. This can be done by using the Play app called Samsung Phone Info.
The stock i747m firmware is available on sammobile.com. Just search for the Bell sgh-i747m 4.3 ROM. You can flash it using Odin. Do NOT check anything except auto reboot and F.reset time. I recommend using Odin 3.07 and backing up your important data to your computer as flashing with Odin will wipe your phone.
MY sister called ATt to unlock her phone when she went abroad, they did. Now she no longer has ATT and is with tmobile. Using the Tmobile sim card, she can't seem to upgrade her OS using the firmware update option in settings. How can she go about upgrading? she currently has android 4.1.2 with the NOte 2?
also if i flash aokp on her phone, but she don't like it, then flash back the original 4.1.2 firmware, would i lose the unlock that ATT did for her and she can't use Tmobile anymore?

Unlock is permanent ok.
Ota updates come from AT&T servers, meaning you'll need to be on AT&T network.
Btw plenty of stock 4.4.2 Roms in the development section you can flash for her.
Aosp is to buggy and isn't official 4.4.2.

Hi to all, im new on the forum, i was looking to find a way to unlock my S3 t999 which has the android 4.3 JB, i got a lot of info but it seems that i only Rooted my S3, i found out that there an easy way to do it whit the Service mode but since i have Stock 4.3 its impossible, was looking a way to downgrade to 4.1.1 but probably ill get a brick, so if there any way that i get some help unlocking my device i sure will appreciate it.
After 4.1.2 I think there is no free alternative available (unless your carrier gives unlock codes for free after a certain time period). The best way to unlock your phone would be by contacting your carrier for an unlock code which usually means paying a fee or using a pay service. I would recommend using your carrier because they will offer better support and this would reduce your risk of getting scammed by a online service.
Help please!
Hi! Where do I begin?! So I have a tmobile s3 T999LTE version. Previously I rooted it because I wanted custom rom on my phone. Then I wanted to sell it so I unrooted it. I had read somewhere that after unrooting I should revert to latest stock firmware which was 4.3...BIG MISTAKE! It's now running on 4.3...LUVUBOH1 and I CAN'T UNLOCK IT! Tmobile had sent me a code which did not work, then I switched to metro pcs and purchased a code off ebay,which was the SAME code tmobile had given me. I now have metro pcs on another phone and when I put in my current sim in s3 it doesn't prompt for code! And no key combos are working due to change in dialer. I am stuck and gave no idea how to fix it. Imei is valid and I'm pretty sure I'm running stock 4
3. Help anyone? Please? ???
Was the phone running a completely stock rom when you tried to enter the code? How many times did you try to enter the code?
