Want to free unlock mjb att sgs3 - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

My phone has mjb modem I tried the method which is confirmed working in 4.1.1 but in 4.3 it seems not to work... Phone is rooted. Any advice? When ever I insert an other not supported sim it says no sim inserted. I have sr3x rom.

Your success in using the free unlock would appear to depend on which bootloader is installed on your phone.
If you have the MJB bootloader you are most likely out of luck. If you have the MJ2 bootloader it is probably possible. I reference this post found in one of the unlock threads:

Thanks, so it seems I am out of luck since my phone once had bricked and I unbricked with full mjb firmware... My modem and bootloader is mjb... No free unlock working with that.

@Najuto9tail, there may still be a bit of hope. I came across the link to this post today in a comment by DocHoliday77

Once updated to 4.3 (MJB), you cannot downgrade, even just the modem. The requirement for the free unlock is the 4.1.1 modem, and since it won't work, you can't do the unlock.
The only way I know of is by using an unlock code either from AT&T or one bought online. Sorry.

Yeah I thought that it would be like that. Thanks. I do not need to unlock it anyways, I solved the problem which wanted me to change carrier.

Bootloader unlock allowed no

Hi all
Is there a way round this I have read a few things but a little confused
Thanks

I think testpoint unlock will work

According to
http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/
If it says the Bootloader unlock allowed is NO the bootloader is already unlocked is that right ?
That can't be right because mine is looked to orange and also says 'no' for boot loader unlocking and i have installed a bug fix update OTA and 2.3.4 via pc companion which would both brick a phone with an unlocked boot loader and mine downloaded fine.
Mine said no to unlock bootloader and was locked on o2 but I paid to have the sim unlocked and the bootloader for a small price of a web site, its a 100% safe and also you can still do OTA updates with out a brick.

Use jinx13 on this website, he unlocked my play, he will provide you with all the software you need, he does the unlock remotely using teamviewer, all you need is a paperclip.

No not at all, you don't need to sim unlock your device before you unlock the bootloader. Infact one of the features you get with the paid unlock method is, it will sim unlock your device too. So paying for a sim unlock first is a waste of money.

I looked every were and im sure every unlocking bootloader method was you had to have your sim unlocked first. If I new that I wouldnt of payed and I would of done it my self.

I'm serious, i know there is alot of conflicting information right? But the deal is, factory unlocked phones can use the official bootloader unlock method. Sim locked phones, even if you get the sim unlocked, it does not unlock fastboot, thats why you need the testpoint method, and a sim unlocked device defo isnt required for that, because my device was still locked to o2 when i got my bootloader unlocked.
Sent from my R800i using Tapatalk
Ok lol I looked at to much conflicting info then. I knew I should of just tried it. Do you still get OTA updates with out bricking?

He unlocked my bootloader and sim within 15 minutes. I don't think you need to unlock the sim first because mine was a r800at and everything was locked to begin with.

If you think you can unlock your bootloader using the unlock method your self then do so but you wont be able to do OTA updates but if you pay you will be able to do OTW updates.

Unlocking Carrier

Hi my friend has my old galaxy s3 and its an ATT one and its still on the old 4.1.2 with the old modem and its unlocked carrier wise so he can use his T-Mobile Sim card. If I update it to 4.3 or the latest modem is it going to still be unlocked/ be able to be unlocked?

Yes it will, an unlock is permanent and cannot be undone. But if you ever want to root or flash a rom, I would not suggest doing this due to the fact that 4.3 makes rooting and flashing roms difficult, not to mention that you will not be able to downgrade.

How to unlock bootloader?

Hey guys, I need some help. How can I unlock the bootloader on the N3 and root it? This is my first time to have a locked phone. Altough it supports different SIM cards, the bootloader is locked. And yeah - should I wait until KitKat update comes out or should I root it now? Thanks in advance!
Sent from my SM-N9005 using Tapatalk
Great thing about T-Mobile is bootloaders are not locked. Just root first from here http://forum.xda-developers.com/showthread.php?t=2466423 and install your custom recovery afterwards.
Sent from my SM-N900T using Tapatalk
The T-Mobile Note 3 does not have a locked bootloader, simply use Odin to flash a custom recovery and/or root the stock OS. It is carrier locked but not bootloader locked. Only the AT&T and Verizon variants are locked (and I think Verizon has a "developer" unlocked variant).

Thanks for that, but when I search for ROMs should I download roms for the international version of Note3 or Tmobile? Or is there any difference since bootloader is unlocked? And how can I root without tripping KNOX?

This was answered in your other post. You gonna need to read and research. Knowledge is your friend. The devs here put in the first line what phones the rom will work for. If it a T-Mobile phone then you in right area.

[Q] Samsung Galaxy S3 T999 Android 4.3 Sim Unlock

Is there anyway to Unlock the Samsung Galaxy S3 T999 with Android Version 4.3 , I tried everything , Downgrade Firmware , Change Modem to UVLJC and nothing . Help please
Flash a 4.1.1 or 4.0.4 ROM and modem (not Odin, or you will brick), then follow the unlock guide.
Alternately if you have the phone thru T-Mobile they will unlock it for you if the bill is current, or you can buy an unlock code online for under $10.

It doesnt work that way either. It lose the imei with a different MODEM, you need to flash it again the New Modem to recover the IMEI. Please I need to unlock this device. Any ideas?
Where 4.3 is concerned, there is no way to unlock using any of the previous methods. Your best bet is to call T-Mo
Im having problems sim unlocking as well. T mobile sent me a code that does not work. Still waiting on there help. Suggestions?

Well after calling TMobile again and spending close to an hour on the phone they escalated me to "Someone Will Call You Back" LOL
So Today I downloaded the stock 4.1.1 and loaded with odin. Then Used the steps in the below thread to obtain sim unlock without TMobiles help.

sim unlock 4.3
You only have two options... Option 1, You wait until kikkat 4.4 become available for upgrade then unlock the phone with same code. Or option 2, you find the stock rom that came with the the phone which is the ice cream 4.04. Then use odin to downgrade and then you can use the same code.

Does using it require an unlocked bootloader, and will it unlock the bootloader in the process?
Trying to help my friend root so he can back everything up, then unlock his bootloader.

For T999, if its on 4.2.1 or prior version of Android, then the bootloader is unlocked. If its on 4.3, the bootloader is locked and there is absolutely no known way to unlock it.

And that would mean there's no way to root on 4.3 if my friend is already there, correct?

Hmmm.............. Well, not quiet. But the problem is, you may trip that dreaded warranty bit. Visit the Root66 Thread and flash that image UVUEMJC.

Would flashing the 4.3 from that thread lock the bootloader? I don't think it will, but just want to be safe.
Sent from my MB886 using Tapatalk
Since the phone is already locked, that Rom won't re-lock it. It won't unlock either. That's why I recommended that Rom (UVUEMJC). If you tried prior Root66 roms, you will brick the phone.

His phone is on 4.1.2 so the bootloader should be unlocked. If he were to flash the Root66 4.3 would it lock the bootloader?

Do not flash the root66.. instead flash a custom recovery with Odin and then flash a stock rom and update modem if you're gonna flash 4.3.. that is the safest to do it if your friend cares about warranty.. you can still flash the root66 and it will be rooted but it may trip the warranty bit, I'm not too sure

I'm fairly sure his warranty is up unless it's lifetime, because he's had it for 2 years. Either way, I was just checking in case he decided to, I think he just wants to root 4.1.2 and stick with that for now.
OK then just use cf auto root.. It even works with 4.3 so no need to worry about bootloaders or anything
