I just want to be sure about something...
If I flash a new Stock (or custom) ROM, will it somehow cause my carrier unlocked device to be locked again?
Nope. All will work just fine.

Okay, I have unlocked the bootloader and all. If something ever goes wrong, does anyone have the stock firmware download? And how would I go about putting it on an unlocked bootloader? Or will I have to lock it again? Thanks :-D

You can find the newest GB stock firmware on this post:

and the newest Flashtool to install it here:

As I'm aware the newest firmware and penultimate .62 cannot be rooted, however you do not need to unlock your bootloader again. Once it's unocked you can flash another kernel or custom rom on it even it you re-install the original firmware. The custom rom should already be rooted.
I revert to stock first everytime something goes wrong like bootloops just to make sure I have the right baseband and stock kernel.
or u can try this

I'll be going on a trip to China soon and I need to unlock my phone. I have tried unlocking my phone with the help of this post, but unfortunately it didn't work out. I read that I need to be using the stock rom for the unlock method to work.
My question is: if I unlocked my phone on the stock ROM and then restored to a backup with Clockworkmod, would my phone still be unlocked?
Also does anyone have a link to good stock based ROM that I can use to unlock my phone?
Any stock based Rom will do it, even the plain rooted stockones. And once it's unlocked, it stays that way until you relock it. Flashing a Rom shouldn't cause you to relock
I am selling my S3, and I have been out of the loop for quite a while because I've had a Nexus 5 for the past few months. My S3 is rooted, unlocked, and running Cyanogen 4.2.2. I had AT&T give me the unlock code a while back, so its unlocked.
My question is, how do I go about restoring the phone to stock, without loosing my carrier unlock? I dont care about losing root, but I sold the phone as "unlocked" so its pretty important I keep that.
Does flashing another rom effect the unlock status at all?
Once a phone is unlocked. Its unlocked permanently no matter what you do to it. I would suggest restoring back to stock 4.1.2 after running triangle away to reset flash count. Then sell it and let the nre owner choose If he wants to update to the new 4.3 if they want

Restoring to stock would depend on what firmware it was on prior to the custom ROM installation. If it was already on 4.3, then a restoring stock 4.1.2 would not be an option. Also, you may not be able to find a stock image for 4.1.2 flashable via Odin as the only route to 4.1.2 -after OTA- is via a manual update from stock 4.1.1. Therefore, if it wasn't already on 4.3, the best option may be to flash stock 4.1.1 via Odin. The required files and instructions may be found here ... http://fortedge.com/downgrade.html
A correct factory unlock (e.g. via carrier assigned unlock code) would indeed survive all firmware changes.
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.
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.

Ok I tried the code and it didn't work.
I'll read up on the Odin procedure... I've done it before on another phone but I wanna make sure I don't end up with a brick! Thanks!

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 =)
