So upon searching, I've found that I need to be on a stock or stock-based ROM to unlock (using this method: http://forum.xda-developers.com/showthread.php?t=2176719&highlight=unlock )
I'm currently on CM10.1 nightlies, so obviously I need to get to a stock or stock-based ROM in order to do this. Again, searching led me to this thread: http://forum.xda-developers.com/showthread.php?p=33570269#post33570269
This allows me to use ODIN to flash stock touchwiz.
My question is this: is there an easier way to get to an appropriate ROM than using ODIN? It's been approximately a year since I've last used it, and I would prefer to just flash a ROM like I would a new CM nightly. Which ROMs are suitable for me to flash which will allow me to SIM-unlock my phone?
Also, if I make a nandroid, flash the stock ROM, unlock, then restore the nandroid, will I keep the unlock? Or is the best way about doing this: wipe data/cache, flash stock ROM, unlock, wipe data/cache, flash CM?
Thanks in advance!

I am running IOKP 4.3.1 on my nexus. I have downloaded the OTA update for kitkat 4.4. Can I flash the 4.4 update from cwm or so I have to return to stock then flash it? I ask this because my stock backup will not restore due to md5 mismatch. Thanks for any advice.
Anyone?
Just backup, restore a flash the 4.4 ROM.

OK I've backed up iokp. Can I now flash 4.4 from cwm? Or do I need to flash stoc first?

You can only flash an OTA if you are on stock ROM.
OK but how do I get back to stock ROM then? My backup won't restore.

If you don't know how to flash back to stock manually you are probably better off using one of the toolkits in the development forums.

Tasssadar has some stock flashable zips here:
http://forum.xda-developers.com/showpost.php?p=48544617&postcount=255
Don't forget to thank him if you use it.
They seem to be stock kitkat. I would need to flash stock JB and then flash KK though, yeah?

No. Just wipe(cache, dalvik cache, data, and system) and then flash KK and you are done.
Another edit: Since you can't use a computer for this, you should download a few other ROMs so you have something else to flash if something goes wrong. I would really only recommend upgrading if you have access to a computer. Things can go wrong very easily. Good luck.
Thanks very much!
They aren't update custom ROMs, they're like factory images. You just need a kitkat 4.4 custom ROM that you can flash in custom recovery. If you don't have custom recovery on your tablet, you need to use your PC to flash it, or just boot temporarily.
Afterwards, restore your tablet, clear cache and dalvik cache, install zip, choose your custom rom, and flash it.
If there is an update for a ROM (such like nightlies for CM) you wouldn't have to restore the tablet, just flash the updated custom ROM because it's just an upgrade.

Hi,
I bought a locked Samsung S3 (At&t). It is rooted with cyanogenMod 10.2 Android 4.3.1. All i was trying to do is unlock it so i can use it with other carrier. So i bought the unlock codes for 30 bucks but later i found out that the unlock codes only work with Stock rom. I am not an expert at this Root, Custom Rom...stuff, but not idiot either i can follow step by step directions if anyone knows how to make this work. I would like to use the custom rom though, so do i have to recover in stock rom, unlock the phone using the code and than install the custom rom again?
Plz help
Hi!

Yes, that is what you will need to do. As you can only enter an unlock code on a stock ROM (or one of the numerous custom ROM based on the stock one), you won't be able to make it work on CyanogenMod or any AOSP derivatives. You will have to revert back to stock, then (if you want to try a cutom ROM) install another custom ROM of your choice, be it CM or anything else.
Though if you currently have CM installed in your device, you most certainly already have a custom recovery (TWRP, CWM, PhilZ Touch...), which make it even easier for you to flash ROMs at your will -- the step of installing a custom recovery is already done. So browse the AT&T SIII Android Development forum, choose a stock-based ROM, install it -- pay close attention to the installation instructions in the ROM's thread --, unlock your phone; then repeat those steps to install another ROM if you want to.

Could you please direct me to how to unroot? I am able to go into the recovery mode but not really sure how to go on from there. I appreciate the help.

Before you flash a stock ROM, you would need to check what bootloader your phone is currently on as flashing the wrong one could cause your phone to brick or become unusable. Custom ROMs like the CM you currently have do not have their own bootloaders but rely on manufacturer's bootloader to run. The bootloader, quite simply, is a small application that loads the operating system and all other applications & systems required for the phone to run once it is powered on. Therefore, with a faulty bootloader, your phone can not gather all the resources required to power on successfully. If your phone is running on the 4.3 bootloader which would be the case if it was on 4.3 before the update to a custom ROM, then you would have to return to stock Android 4.3 which is the latest OS available for the AT&T GS3. However, if it has an older bootloader, then you can flash Android 4.1.1 via Odin.
There are different sets of instructions for either system so I would suggest you check your phone's settings and advise the OS parameters you can see there so we can steer you in the correct direction.

Did the phone originally have 4.3? or did it have an older version before you installed CM 10.2. This would determine how you would go about it.
Also is there a custom recovery like clockworkmod installed?
I'm currently on G2 apps rom V5, but wanted to try out KitKat and Sphinx rom,
I know there is the KDZ method of going back to stock, however I was wondering if I could load my backup from stock JB 4.1.2 before installing G2 apps V5, unroot, and then work from there. Is this method possible? Thanks!

I don't quite understand what you're asking, but I'll try my best to answer.
Are you asking about the stock OTA Kitkat when you say "Kitkat"?
If so, then if you restore that backup, then you'd also have to somehow restore the recovery or else the OTA will not work.
You will be back on stock 4.1.2 though and can flash any rom you want, so if you get one of the flashable versions of the stock Kitkats, then you can flash it without issue.
If you are on the E980, then the flashable Kitkat is here: http://forum.xda-developers.com/showthread.php?t=2760895
You shouldn't have to return to stock to flash Sphinx. All you'd need to do is format System, Cache, Dalvik, and Data, then flash.
Thanks for the reply sorry for not being more specific.
I have a 240L that was on 4.1.2 when I rooted and flashed the g2 apps rom.
I have been reading that I will brick the phone if I try to flash from my current rom, and that I need to OTA update from 4.1.2 to 4.4.2 as well. I didnt realize about the stock recovery though so the only way to get that back is thru flashing the KDZ file anyway?
Thanks again for the reply!

I'm currently trying to flash stock firmware via KDZ, however, the method provided on xda is not working for me.
LG Support tools is telling me that my software is updated already and is not letting me flash the KDZ.
What am I doing wrong? Please help, thank you...
I need to dirty flash my current ROM in order to get the benefit of a custom kernel... The only problem is that it's stock. I can find RUUs, nandroids, and similar files for factory restore purposes, but can't seem to locate a stock ROM I can simply dirty flash in recovery.
Would anyone happen to know where I might find one?
Much Appreciation in advance!

does TWRP able to flash a stock rom?
if it possible, will it cause any problem?
my device is rooted and using stock rom (planning to flash CM)
a) if you have twrp installed, then just backup before flashing any other roms, then factory reset and restore to go back to factory if needed.
b) you can flash OTA with twrp, and I ma pretty sure full stock roms too. See this guide. There is a thread on xda too, but I don't have it bookmarked.
I hope that answers your question.
P.S.
Remember that you have to unlock bootloader for TWRP, and if you want to use OTA function on stock rom with TWRP you need to fully unroot first.
