Just flash some old recovery that will allow you to downgrade to 4.1.

Any luck? have the same problem. I was hoping not to downgrade and just let it be on 4.3 JB.
Hello everybody
I have a Samsung S3 SGH-i747M (from Canada) with 4.4.2 and version I747MVLUFNE6 which is locked. It asks for "SIM network unlock PIN".
Is there any way (I don't care for the warranty) to make it work with an other SIM? I am currently in Switzerland.
Thank you very much in advance!
No you'll have to either call the original carrier of the phone and request the code or pay for the unlock code.

Do you know a reliable site where I can ask for the code?
There's lots of them out there. Pretty sure eBay has some and you can judge by their feedback and ratings...can't think of any specific ones right now though.

The problem is that I don't know at which carrier belonged the phone and one page that I found,that doesn't require the carrier and I think read that is reliable (swiftunlock.com), does not include the i747m in the list.
Any ideas or any other sites?
Any that offer it for the I747M should work. Don't take my word for it though. Ask the vendor first.

All the sites that i found ask for the carrier which I don't know or to have the phone rooted and have a version lower than 4.1.1 which I don't .
Is there any way to find out at which carrier it belonged?
Or any other reliable solution?
Please... :crying:
Go yo swappa.com and check the imei. I think it shows the original carrier when it does the check.

Free method will not work unless the bootloader is from 4.1.2 or lower.

That maybe true.....but I do know it doesn't work with ICS or JB 4.1.2 because [4] NW Lock NV Data INITIALLIZ does not show in menu.

Once you are on the 4.3 ot 4.4.2 bootloader, you cannot downgrade the bootloader and the 4.1.1 modem will not work on the 4.3 or 4.4.2 bootloader.
You must be on at least the 4.1.1 dialler and modem.

Hey, I also have a I747 on Rogers on 4.4.2. Im looking to downgrade it to 4.1.1 like you did so I can sim unlock it. What process did you use to downgrade? Was it this: http://www.sammobile.com/firmwares/download/8565/I747MVLDLK4_I747MOYADLK4_RWC.zip/

damnit, just saw this. Is there any way to downgrade to unlock the SIM? What about if im on a different ROM?
There is no free way to sim unlock your phone once you have the 4.3 or 4.4.2 bootloader on your phone.
How to know on which bootloader ( bootloader 4.4.2 or 4.3) I am coz I was able to install a custom rom on my SGH-I747M The rom is dirty unicorn android 5.1.1 lolipop rom so Can I downgrade coz if I remember correctly I upgraded from stock 4.1.1 so can I downgrade to stock 4.1.1 by downloading and injecting it via odin is it possible or will it hard brick my phone and can you give me way to confirm what bootloader I have ???
Boot into download mode and look at the screen. If you see anything about knox, it likely the bootloader can't be downgraded to 4.1.1.

Can you guide me that how to know which bootloader do you have i.e. do I have a 4.3 or 4.4.2 bootloader how would I know that? and also I do have a custom dirtyunicorn rom with 5.1.1 so is it possible for me to flash the 4.1.1 stock SGH-I747M rom to it and then unlock it and then again add my current rom and use it???
Download and install the Samsung phone info app from the play store, run it, and look at the last three characters of the bootloader. If it is mk3 or higher, the bootloader can't be downgraded.

Not quite sure where to put this but I have just successfully sim unlocked a samsung galaxy s3 sgh-i747m on 4.4.2 .This is only prelimary but upon unlocking and inserting a Public Mobile sim I was able to text on a Canadian Rogers S3. No further testing has been done. I first rooted the phone using Kingoroot and then downloaded the phoneinfo app from play store. I then used the app to get to service menu.At first service menu is blank but I used menu ,then key input Q, then back, then key input 0000,then back and then service menu appears. Now I am doing this from memory and no longer have the phone or another one at the moment to confirm this and will update this as soon as I can. But to the best of my knowledge I first went to UMTS(1) ,thenDEBUG(1), then Phone Control(?), then Network Lock.. Perso-SHA256 was on(1) I set it to off (0). I then backed out of the menu and shut down phone.I inserted PM SIM in phone and booted up .Phone didnt ask for unlock code and shortly I had texting service with Public Mobile. I dont have voice or data to check those but cant seewhy they wouldnt work. Anyway can someone confirm this working.My steps may not be exact but if it worked for me it should work for others.
So my Galaxy S3 is rooted running AOKP. I have an unlock code from T-Mobile so I can unlock it and use an AT&T SIM card. When I enter the code after booting the device with the AT&T SIM in it, it says unlock unsuccessful.
Do I have to be unrooted & on stock to do this? Or maybe just on stock? Kind of annoying, any help is appreciated!
EDIT: So I figured it out myself. If anyone has this problem in the future, just flash a touchwiz based ROM then reboot and use the unlock code and it should work.
ok trying to end up with a android 5.0 + on my att note 2.
Here's where im at : already went though the process of requesting unlock via at&t attempted unlock with no success
(unsure if i permanently sim locked to att or not) so now from what i have read i would have to downgrade from 4.2.2 kitkat to 4.1.1 to unlock via loophole? my problem is unable to find my modem/radio (I317UCSCNJ5) im new to this process but does that mean i cant downgrade? i cant seem to find much about nj5 in any of the stickys or the all in one shop any help or ideas would be much appreciated
I just purchase a Samsung galaxy A50 SM-A505U at Ebay from xfinity, I havent received it yet but I was wondering if this specific model from xfinity when you insert a sim card from another provider will asked for a unlock code?
I have a verizon samsung a505u I want to root but am kinda new to all this. Will someone provide all necessary things I need and steps?
I cannot find OEM unlock, I tried steps to getting it to appear and didnt work. When I book into recovery it doesnt even show bootloader whether its locked or unlocked....

I have an A505U as well that's recently off contract and I am trying to root it, not having any luck though :'( My OEM Unlock setting is missing in the Developer Options as well; none of the common methods for getting it to appear work :/
