[Q] Unlocking I747 running CM11 - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hello all,
I'm new to this forum but not all new to the world of phones/rooting/flashing and all that good stuff. I was looking for a way to unlock the i747 so I can use it with different carriers when traveling abroad. The only thing that I found was unlocking it with the stock 4.1 firmware. Is there a way to unlock it while running CM11 or would I have to flash a stock 4.1 ROM and unlock it that way? Also, if I do revert to stock 4.1 and unlock it, when I flash back CM11 will that void the unlock? Thanks for the help!

You cannot unlock the phone using the free method if you have the 4.3 bootloader on your phone. This is due to the fact that you cannot downgrade the bootloader to the stock 4.1.1 bootloader.

Unlocking is permanent. Flashing won't re-lock.
You have to be stock with a stock dialer. But if you have ever updated your firmware/bootloader to 4.3 or later it will not work.

is it true? i have a i747 on cm11 4.4.4, now i thought i just had to pop a tmobile sim and bam!

Is your phone unlocked? If it is, you may only get 2g on your i747m until you enable AWS.

My phone is deff still locked to AT&T and i have to unlock it soon. Any way to do this now that my phone is 4.4.4?

Will you be unlocking the phone using an unlock code? Is the phone running a stock ATT ROM?

You need to be running stock or close to stock in order to enter the unlock code.
If you are running a custom ROM, you may not be prompted to enter the code when you insert a non-AT&T sim.

Yep. Stock ROM is the only way you can carrier unlock the phone.

Apparently, having a working stock dialler on a custom ROM will also prompt for an unlock code. I can't confirm this as I have never used an unlock code on an s3.

[SOLVED]: Rogers Galaxy S3 SGH-I747M

My friend moved back to Pakistan from Canada recently and brought his phone back with him. Since the phone was purchased from Rogers, it was locked to Rogers network in Canada.
He brought it to Pakistan and had it unlocked for 10 USD at a store.
He isn't familiar with rooting and all so he didn't pay attention as to how the unlock was done and is not sure if it was a factory unlock or not.
He showed me his phone recently and I noticed they had rooted it.
He wants to update his phone to 4.3 Jellybean but he can't use OTA because his device status has been changed to 'Modified'.
If I download a 4.3 firmware for the I747M and flash it will the phone get locked again? On SamMobile, there is a firmware that shows Canda (Rogers) on one of the firmwares, if I download it and flash it will the phone get locked again or will it stay unlocked even though its being flashed with a Rogers firmware.
There is also another firmware with the Country/Carrier showing as 'Unknown' as SamMobile. If I flash this firmware, will the device get locked? What does 'Unknown' mean on a firmware?
Thanks
What OS is on the phone right now? If the phone is running 4.3, do not flash any stock firmware unless it is 4.3 or higher.
I don't think it makes a difference as to whether the phone was unlocked via rooting or code, it will remain unlocked after flashing.
I unlocked my Bell s3, as have many others, using a free method and the phone has remained unlocked, even though I reloaded a stock Bell 4.1.1 rom and then a stock Bell 4.1.2 rom.

You can flash it but I would not do it. The 4.3 ROM will install Knox which can make rooting more difficult and harder to unbrick.
You can install a custom recovery and just flash a custom 4.4.2 ROM. This allows you to easily return to a stock ROM in the future.

My friend does want KitKat on his phone, so how do I flash a 4.4.2 ROM?
Can I flash the CWM Recovery meant for the I747? Will it make a difference if my device is the I747M?
Will I747 ROMs work on the I747M?
Thanks for the help BTW
You can flash Philz Touch Recovery via Odin. Once that is flashed correctly, you can download a ROM, save it on the phone's internal or external memory, boot into recovery, wipe Dalvik Cache, cache, and data. Then flash the rom and reboot.

I just started flashing ROMs onto my s3 and prefer an aosp interface.
I don't know of any that look like stock kit Kat but you could use as theme chooser to find something you like.
I recommend that you not update to 4.3.

You can search for themes on the play store. Many of them require a certain launcher. When you find a theme you like, just download the required launcher and install the theme.
Were you able to load a custom rom onto the phone?

I haven't tried yet since the phone is not with me.
To be honest, I've used 3-4 launchers from the Play Store but they still don't give the same experience as the Custom ROM.
Thanks
Every ROM uses some sort of launcher and certain themes only support certain launchers.
Personally, I like Cyanfox because of its dark UI.

Hi, I'm trying to unlock my Galaxy S3 I747M and I see that you were able to do so via a free method, now would that free method be via a survey, or a magazine deal or Netflix? I'm currently in Trinidad and it comes up with something like, Deals are not available in your country. I would like to use this phone while here on a work assignment so if you could please tell me how you were able to do this it would muchly be appreciated. Its on a Canadian carrier and with Rogers. Also on 4.1.2

The free method is not any sort of offer from any company. In order to use the free method, you need to flash a stock Rogers 4.1.1 ROM via Odin 3.07 because a stock 4.1.1 ROM is the only ROM that has the necessary menu options to do it. If you flash a stock ROM, you will loose all of the data and apps on your phone.
The i747m is a Bell phone. I think Rogers is an i747r.

[Q] Much needed unlock method for Galaxy S3 running 4.3

Hey guys, not trying to make the 100th thread this week asking for this, but I've looked through all of them without any close answers. I'm in need of a solution to unlock my AT&T Samsung Galaxy S3 SGH-I747 phone on 4.3 firmware to be able to use a T-Mobile SIM card.
It was unlocked before running 4.4.2 on Quantum ROM and I decided to fresh clean the phone to start new. I so happened to soft-bricked my phone accidentally, but brought it back now to 4.3. Now under baseband version and IMEI it says UNKNOWN.
1) I read that it is possible to downgrade to 4.1.1 without downgrading the bootloader using ODIN. I have no ideas on what ROM to use, and what program to downgrade with since I can't use ODIN.
2) I read that you can call AT&T and request an unlock code. For this to work, do I need to be an AT&T customer? I'm currently using T-Mobile.
Any solutions?
Try and fix your imei/baseband problem first.

Thanks! I'm in the middle of trying to restore my IMEI, however when I dial the number for the service mode, I only have two options under UART: PDA and MODEM. I'm not able to select MODEM either.

DO you have a custom recovery installed? Maybe install a custom ROM and see if you have those options available?
Your imei and baseband may be missing because you don't have a modem image installed.

No I don't believe I installed a modem. I used Looserskaters S3Rx ROM from the "[HOW TO GUIDE] How To Unbrick AT&T I747 and I747M After 4.3 OTA" thread. The rom is located here: http://forum.xda-developers.com/showthread.php?t=2252932
I don't know which modem to use. There's a MJ2 and MJB one.
Try either one. I believe the MJB is the most recent. Flashing a modem doesn't affect the bootloader.

Just make sure you're running the latest version of your recovery. I prefer Philz Touch as I had some troubles using TWRP.
So I was sondering how to unlock if you are on stock mjb... Do the sketchy downgrade to 4.1.1 then use the dial unlock?

instead of using the code *#7284#.. try *#0808#
and once you're on 4.3 bootloader, you can't use free unlock
so buy unlock code or trick AT&T for one somehow

If you have the mjb bootloader, do not attempt to downgrade the bootloader as it may brick your phone. You will have to buy an unlock code as there is no free method available at the moment.

You can downgrade the ROM and leave the bootloader untouched but this will not allow you to unlock the phone using the free method. You need to be running the 4.1.1 bootloader with the 4.1.1 stock ROM.
just the modem
will that work can anybody explain how to do it?
What bootloader is on your phone? If you have 4.3 or higher, flashing just the modem won't work to use the free method. If you have a 4.4 bootloader, mixing modems could brick the phone.

[Q] Can you flash Koodo SGH-I747M with AT&T's Kit-Kat?

I unlock both my Koodo SGH-I747M by following the instructions (just by punching a bunch of codes) from one of those YT video and I've been using T-Mobile's prepaid service since.
http://forum.xda-developers.com/galaxy-s3/general/american-canadian-sgs3-read-flashing-t1757755
Since the specs are all the same for SGH-I747M (AT&T/Telus/Bells/Koodo/Rogers) + my phones are unlock, does that mean I can flash both my phones with Kit-Kat (once released) by any of these carriers (AT&T/Telus/Bells/Koodo/Rogers)?
Thanks.
p/s currently still on the original 4.1.1
I would not do it as att and koodo use different bootloaders and modems.

Glad I asked first, thanks for the reply and it makes sense :good:.
Personally, I would avoid knox as most custom KK ROMs will work fine with the 4.1.2 bootloader. I would only upgrade the bootloader if it was required for a ROM I really wanted to use.
Your unlock means nothing to the ability to install a ROM or not.
Now, you can install the Samsung ported Sprint Kitkat ROM for AT&T if you update your bootloader and modem to the MK5 version and never use ODIN or try to downgrade your bootloader ever again ! This ROM will not work without the MK5 bootloader and modem. If you proceed that way, your warranty will be void
Also, you can always flash Koodo builds
If you wish to keep your current bootloader, you can always install any of the non samsung ROMs, but some will require that you have the MF1 bootloader at the least (CM for example).

Sim Unlock Rogers S3 on CM11 M10 (4.4.4) [SOLVED]

Hi everyone,
I am looking for a way to sim unlock my S3 so my girlfriend can use it on Telus (I just got an OPO )
Before I purchase a code, I have a few questions, if anyone knows the answer
1- Will an unlock code work with my setup? (I am seeing reports of it only working on Stock 4.1 and whatnot)
2- Where is a good place to purchase a code? (Rogers a crooks with a 50$ fee and I don't wanna get ripped off online either)
Thanks!

You will need to be running a stock or close to stock ROM in order to use the unlock code. You do not need to be on stock 4.1.1 to use an unlock code. You need to be running stock 4.1.1 if you want to unlock using the free method. You may be able to unlock it using a code if you are running a stock dialler.
What bootloader or baseband is on your phone?

I managed to get a code from Rogers for half the price, which is "not that bad" I guess...
I have yet to try it as I don't have the SIM card with me atm.
Baseband: I747MVLUEMK5
it's my understanding that downgrading from this will brick your phone...
Thanks for all the info!
Yes, trying to downgrade from mk5 will brick your phone.
Find the stock Rogers ROM from sammobile.com and flash it via Odin. Flashing back to stock will wipe all user data and files so make sure you backup everything you need before flashing back to stock.

ah one more thing... since I'm using the unlock code (I don't believe the free method works on Rogers phone anyway) should I flash to stock MK5?
If I go to stock MK5, eill I be able to come back to CM afterwise?
Thanks!
The free method will only work if you are running an i747 or i747m on stock 4.1.1 including the bootloader.
If you flash back to stock mk5, you should be able to re-install cwm and CM11. There are many threads on disabling knox and install CWM.

Hi! Reporting back, everything worked well flashing stock rom using this method:
http://forum.xda-developers.com/showthread.php?t=1739426
I had a slight problem after the Odin flash where I had to boot to recovery and factory reset to get out of a boot loop, but everything went fine after that.
I managed to unlocked the phone, changed the recovery using the aforementioned thread and got back up and running on CM11 M10 in no time!
Thanks a lot for your help sir =)

You can downgrade the ROM but not the bootloader. Attempts to downgrade the bootloader will probably brick the phone.

Are you trying to downgrade to 4.1.1 to sim unlock the phone using the free method? If you are, this will not work because the 4.1.1 modem will not work on a 4.4.2 bootloader. You will need to obtain an unlock code.

You will not be able to downgrade the rom to 4.1.1 while keeping the bootloader at 4.4.2 because the modem will not work on a 4.4.2 bootloader which means you probably can't run ota updates.
To downgrade without touching the bootloader and modem, you need to use mobile Odin. Also, you will have to find a source for the 4.1.1 stock rom since att pulled it from sammobile.com.

Willl this work If i flash with mobile odin?
sammobile,com/firmwares/database/SGH-I747/
You may be able to flash 4.1.1 with mobile Odin but ota updates probably won't work due to a mismatch between the bootloader and rom. Also, the ota updates normally get applied in order: first, 4.3, then 4.4.2.
So in Theory If we flashed back and was a success...
Then we can do the unlock and flash back to 4.2.2 then rom it again ?

Any chance their emails are ending up in a spam/advertising folder and not making it to your inbox?
I've had no problems with AT&T unlocking phones in past. As long as you're "eligible" (I assume that means off contract) they email the codes and instructions, no fuss.
