I am attempting to SIM unlock my L520 that's running MK1 baseband. I am not able to find older modems to flash onto my phone in-order for me to sim-unlock it. Would it work for me to flash a Sprint GS4 modem onto my GS4 mini instead? Any ideas?

Hello,nope, perhaps this device cannot be unlocked with this procedure. S4 mini is not supported for SSU.APK. I have successfully unlocked and rooted, S5 G900P, Mega L600 and S4 L720 and L720T, (L720T gets 3g and L720 Gets edge speed).

I am an AT&T subscriber and in the market for an LG G3. The AT&T version comes with a locked bootloader which means I will probably never be able to install a custom recovery and flash CyanogenMod on it which is a must for me. I realize that other versions will not work with AT&T LTE and I am completely fine with just HSDPA+ - which versions of the phone support AT&T HSDPA+ and come with unlocked bootloader?

Thank you. Does it come network unlocked? I.e. can I put my AT&T sim in and use it?

No, but I've heard of getting unlock codes for as little as $6 on Ebay.
Plus Tmo is rumored to start a new thing soon where they put an unlock app either on the phone itself or on the Play Store and you can unlock it right there.
You'd want to get the Tmo version, though, because it's fully compatable with AT&T's LTE bands.
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.
Hi everyone,
Is there a way to flash the AT&T or any other Stock ROM to a T-mobile phone ?.
I'v tried ODIN (version 3.7, 3.8, 3.9 and 3.10) .and I can´t manage to get it flashed.
Tried by TWRP too, and it says thet the zip isnt good.
Thanks in advance.
Not directly, no.

You mean inderictly is it posible? (dont know how is inderectly ).
Yes, but it requires a seasoned developer to make the modifications necessary. I'm not sure why you'd want to do this though as the AT&T version is far more bloated.

Thanks for your reply.
I absolutely have no that kind of skill.
Anyway, the real reason I came up with that idea is because I cant unlock my T-mobile phone, and I live outside the US.
I've heard and read that sim unlocks by code are having problems.
Unfortunately, flashing firmware will not aid you in unlocking. Have you already tried buying a code for your device?

He said flashing a rom not firmware. Someone over in the s6 forums flashed a metro pcs rom and was able to unlock the tmobile s6.

ROM = Firmware. They're interchangeable terms. Also MetroPCS is owned by T-Mobile, so I don't see your point. Flashing software does not unlock the SIM card slot.

There is no MetroPCS firmware for the S6 Edge as they do not sell it.
my bad this works only on s6...didn't realize you had an Edge
Im living outside of usa .
I have flashed my t mobile s6 using metropcs and unlocked my s6 using a code purchased online.
I reflashed my t mobile software and its still unlocked.
Can i update to stock 5.1.1 using odin and have the device still unlocked .
Once phone unlock is done using a code is it a permanent unlock ?

Your phone was unlocked by code. It is permanent. It is not rom dependant. Just like you flashed a different rom than the metro pcs when you originally unlocked your phone, you can upgrade too.
Flash unbranded rom
I have an unlocked G920T (came locked from amazon, but unlocked easily via device unlock app preloaded)
Is there an unbranded firmware I can flash, even if its from a different variant?
Im also interested to know if i can flash a at&t firmware on my tmobile s6. Not for unlock but because the person i gave it to wants to use the ohone on at&t and feel like its an at&t phone. Whatever right? But can i do that? Or would it have to be a custom rom? Orignal firmware would be nice.
Hello all,
I have galaxy s3 i747 that is network unlocked, it was already unlocked by the time I bought it used from a third party. It is now currently on stock firmware 4.1.2, however I'm willing to upgrade/flash stock 4.4.2, my question is that after I flashed my required firmware will it get relocked again ?
Once the phone is sim unlocked, it will remain unlocked when upgrading or changing ROMs, bootloaders, and modems.
