[Q] SIM/Network Unlock on Cyanogenmod - T-Mobile Samsung Galaxy S 4

My searching seems to be giving me mixed answers about this. Is it possible to unlock my SIM while running Cyanogenmod? Currently on 4.4 and installed using the Cyanogenmod Installer months ago when I bought the phone. I'd prefer to not have to revert to stock. I'm traveling to Sweden in just over a week and I received a code from T-Mobile to unlock it. Has anyone had any luck in this situation?

You must be on stock

I figured. Is using Odin to flash back to NB4 the correct/best way to go? I really haven't followed any development/recovery methods for my phone since I installed with the CM installer almost a year ago.
EDIT: Can I make a nandroid backup with CWM of my current ROM (Cyanogenmod 4.4), use Odin to flash back to NB4 4.4.2, unlock my SIM, and then restore back to the Cyanogenmod backup?

Yes.. Or you can also flash a touchwiz ROM, unlock, and then restore your nandroid

You mention that you haven't followed any development/recovery methods in almost a year after flashing the CM installer. If you've never updated either through Kies, Odin, or OTA... and have used nothing but custom ROMs, there is a chance you'd still be on the 4.2.2 (MDL) bootloader. It would be worth finding out before you go flashing 4.4.2 through Odin and giving yourself KNOX if you can avoid it.

If you can't flash a KK ROM, you may need to update your bootloader. If you're not on a 4.3 bootloader, try and avoid it for now.

There is a 4.3 bootloader that would be installed if you ran an OTA update to 4.3 or you manually installed the 4.3 bootloader.
Did you make your backup using Philz? If not, make the backup using Philz, then wipe and install.

Doesn't really matter but it's good to know that you need to stay away from any attempts to downgrade the bootloader.

You can't restore to a completely stock ROM not that you have a 4.3 bootloader. AT&T never released a full 4.3 stock ROM, only an update to 4.3 from an earlier stock ROM.
If you did not have a 4.3 bootloader, you could install any stock AT&T ROM such as 4.1.1. Being able to restore to stock 4.1.1 would also allow you to sim unlock your phone for free, if necessary.

well im on rogers and its the same as att. i still have the original samsung touchwiz 4.1 rom just incase anything happens.
Your original post said you have an sgh-i747 which is an AT&T model. If you have a Rogers s3, it's an sgh-i747m.
Regardless of which model you have, you can't downgrade from any 4.3 bootloader which means you can't completely revert back to 4.1.1. The best you could do would be to run 4.1.1 on a 4.3 bootloader.

I prefer Validus version 4.3 because it includes Nova Launcher and it has a dark UI theme.
but thats 4.3. i wanna be on 4.4 and im installing nova and making it the way i had it before.
wait a second is it a 4.4 rom?

It is a 4.4.2-based rom. The release is version 4.3.
hmm interesting...you do recommend it? what great features does it come with?
I like it because it's a very stripped-down ROM, has a dark UI, and is AOSP-based.
It's not radically different from other ROMs but has exactly what I want. I run the same ROM on a Nexus 4 and Motorola Atrix HD.

[Q] Downgrading CM11 to stock 4.3 on i747M

I know there are a few threads regarding this issue but I can't seem to find a definitive answer.
I am currently running stock 4.3 jellybean (rooted). My phone hasn't received the 4.4 KitKat update yet, so I wanted to install CM11 in order to get KitKat on my s3. However, I heard CM11 can be buggy on the s3, so in case things go south, I want to be able to revert back to the stock 4.3 rom. Some people have said that you can easily flash the stock ROM via ODIN. However, others said that downgrading from 4.4.2 to 4.3 will hard brick the device since installing CM11 updates the boot loader. So downgrading to 4.3 stock with a 4.4.2 boot loader will cause a hard brick according to other threads I've seen. My question is, how can I downgrade from CM11 to stock 4.3 safely without bricking? Thanks in advance.
If you are sure you are using a Canadian version of the i747m, you can flash back to stock in Odin using a stock 4.3 ROM for the phone's original carrier (Bell, Rogers, Telus).

Yes I got the phone from Rogers, it's most definitely i747M. But do I have to worry about any issues with the bootloader? I'm assuming installing CM11 will install the 4.4.2 bootloader, so if I choose to downgrade to the stock 4.3 rom, will it cause any issues seeing as I'm running a 4.3 rom with a 4.4.2 bootloader? I just want to make sure because I heard it can cause some serious problems if the bootloader is newer than the rom.

I have never come across a custom ROM that touches the bootloader. A compatible bootloader has to be loaded on the phone before you attempt to install the custom ROM. Supported bootloaders can be found in the ROM's updater script.
I assume your phone has no warranty since you rooted it on stock 4.3. Did you root it by installing a pre-rooted ROM?
You could copy a ROM to your external SD card, install Philz Touch via Odin, reboot directly to recovery, create a nandroid backup, wipe cache, Dalvik, data, and install your KK ROM.

Okay, I was just making sure because I know OTA updates can change the bootloader, so I just wanted to make sure the custom roms don't do that. As for the custom recovery, are you recommending Philz Touch over CWM and TWRP? Do you know which custom recovery is installed from the CM installer?

Oh and one more question, my phone was originally carrier locked to Rogers and unrooted on 4.3 jelly bean. I brought it in to a cell store for them to carrier unlock it for me, but they used a rooting method to unlock it (because SuperSU was installed on it when I brought it back). They didn't unlock it with a code, so I'm guessing they used something like Samsung Tool or z3x shell. If I install CM11, will I lose the unlock, considering it's more of a "soft unlock", or is the unlock permanent regardless of how many roms I flash? Thanks for your help!

Philz is based on the latest release of CWM and I prefer CWM over TWRP because I had problems flashing ROMs. Once I switched to Philz/CWM, no more problems.

The unlock should be permanent. I unlocked it using the free method when on 4.1.1 and no ROM has ever caused it to re-lock. Reflashing a completely stock ROM, including the bootloader, did not relock the phone.
Please remember that flashing and changing ROMs will always carry a risk of soft bricking or hard bricking your phone. Make sure you read all of the guides and be prepared for disaster.

[Q] Help!! ROM flashing problems

Before I get to the point let me explain what happened. I attempted to root my S3. It did work up until I got to the point where I was ready to flash a ROM and it didn't work. I received the "status 7" error on CWM and I receive an error on TWRP that means the same thing. So what I did since I couldn't restore from a backup that I would get bootloops from, I attempted to install a ROM that was .tar or md5.tar through ODIN which only worked for original firmware (given in the screenshot). I have managed to install this ROM on my phone through TWRP but unfortunately it is for TMobile and somehow my AT&T service works on it. Here is a screenshot of the phone. I have tried flashing "aokp_task650_d2lte_kitkat_6.3.2014" that is made for the AT&T S3 but no matter what I try to flash it will not flash. I have already tried doing the "ASSERTS" method but it did not work. Can someone please help me fix this issue??? :/

The hybrid firmware thing shouldn't really happen but for some reason, cross flashing between T999 (T-Mobile) & i747 (AT&T) sometimes happens without necessarily causing a brick. I would suggest you do a complete stock restore to AT&T 4.3JB firmware (UCUEMJB). Thereafter, you can go back to flashing your preferred custom ROM. Since you appear to be able to get to TWRP, you can first, from custom recovery, remove all existing firmware including OS and then reinstall the stock firmware. It appears the bootloader is still UCUEMJB so flashing AT&T stock firmware shouldn't be a problem. Please see the thread below for 4.3 stock restore...

So in this case, I just flash everything that it gives me correct? Is the stock ROM still rooted? If it is not then what rooting process do you suggest I go through? If it is a rooted ROM.

It's a complete stock image which will take you to as near factory condition as you can get. This means it is unrooted. You would need to re-root after (successful) firmware installation. Prior to flashing the firmware, please remember to use custom recovery to remove all existing firmware including OS. Once you've restored the firmware, there are several ways to root but my preferred method is SafeRoot. You can find the download links and instructions to SafeRoot in the thread below ...

[Q] Questions about going back to stock.

Hey guys,
I was running Cyanogenmod 11 for a while which I installed using the automatic tool online. During the summer I flashed Dirty Unicorns but I have issues with the camera and random rebooting. I just got a Galaxy Gear for Christmas and I've read that its only compatible with touchwiz roms.
I'm trying to go back to stock and I am ok with losing my root access.
I have an SGH-1747m on Baseband I747MVLUEMK5 and my service provider is Bell. The android version is 4.4.4 currently. Whats the easiest method to do this? I've read some concerning information that going back to an earlier version of android will soft brick your phone, but I believe the most current Bell firmware is still in Jelly Bean.
Is it as easy as downloading the correct firmware and flashing it using Clockworkmod Recovery?
Thanks
You should download the stock ROM from sammobile.com and flash it in Odin to get back to stock.

Also, before flashing should I make a backup with Clockwork Recovery or any other program? Will Clockwork Recovery still be present after flashing with ODIN?

Yes, flash the latest firmware for your phone. Be sure it's firmware for the i747m and not anything else. Always make a backup if you ever screw up or want to go back to where you are now. You will lose everything by flashing the stock firmware with ODIN, even clockwork mod recovery.
Thanks. When I made a backup before going to Dirty Unicorns I used Clockwork Recovery. If Clockwork will be deleted by flashing with ODIN, how would I utilize that backup if I needed it? Should I use another program to back up?
EDIT: I flashed it and everything went smoothly. Sincere thanks to everyone who gave me help!

How do you unlock an i747M locked to Fido? [OctOS L 5.1.1]

So I'm planning to switch carriers and I'm wondering how I can unlock my i747M locked to Fido that's running OctOS L 5.1.1. If I have to downgrade, how do I transfer all my current app data and pic's. Also, is it possible to keep the unlock if you were to update you phone to a higher version or install a custom ROM or install the nandroid backup you made before unlocking? Please leave me with some important things to know about while unlocking your phone if possible!
If the phone is running a 4.3 or newer bootloader, you'll have to buy an unlock code.
In order to enter the unlock code, the phone should be running a stock samsung ROM from sammobile.
I suggest creating a nandroid backup with TWRP, copy the backup to your computer, flash the stock ROM, perform a factory reset after flashing stock, unlock, flash TWRP, restore nandroid.

so, in a nutshell, i just need to downgrade my phone to a stock rom of 4.3 or below and just search up a video of how to unlock it using the keypad method?
than if i wanted to, i could use the nandroid backup i did before and flash it and still have an unlocked phone?
You cannot use the free method once the phone is running a 4.3 or newer bootloader because you cannot properly run the 4.1.1 modem on a 4.3 or 4.4.2 bootloader and the 4.3 or 4.4.2 bootloader cannot be downgraded to a 4.1.1 bootloader.
Before flashing anything, which bootloader is on the phone?

Sorry for the noob question, but how do i found out my bootloader?
If this helps, my baseband is I747MVLUFOB3

From what ive heard, you have to be on a stock rom. As of google, even then, some users have problems or cant, which from what ive heard, can be fixed by downgrading to 4.3 (make sure ur bootloader is the same or your phone WILL be bricked).
Please note that this is from what ive heard and may not be accurate.

Do you think this one would work?
https://z3x-team.com/forum/topic.php?id=9505
Whats a CWM anyways?
CWM is Clockworkmod with is a custom recovery. CWM is outdated as it has not been updated for quite some time. Many recent custom ROMs now require TWRP.
You may be able to software unlock the phone but you'll probaby need a UART cable and Samsung Pro tools. I don't believe Pro Tools is free.
The linked thread is from 2014 and, in 2014, many phones were running 4.1.2 which meant the phone could be downgraded to 4.1.1 using and sim unlocked using the dialler's menu options.
