I've for a AT&T S4 I337 with the MF3 update. I have already managed to root it. Is there any way to unlock the sim?? I have searched. Tried to get to the service menu and it does't let me do anything. Can I flash another rom or do something so I can unlock it.

Seeing how you are on the MF3 currently there is no way to flash another rom or custom recovery, your best bet would be go through att to get the unlock code.
But it won't even let me get into the service menu. I tried the codes and process they say online and it does nothing. Can someone explain why it won't budge and how and when it will be fixed?

The service menu unlock was disabled in MF3. You have to get an unlock code from your carrier or another service.

Theres not even a place to enter an unlock code. I cut my Straight talk sim with the proper tool and inserted it and it didn't even recognize it. Still says "no sim inserted." Going to try to buy a ATT straight talk sim from the Straight talk website next.

I ported my # over from AT&T today to Straight Talk. At first it didn't like the new sim card, but after my # was ported and a few reboots the message didn't come up anymore. I now have phone & data service running on it, even though I was still under contract for a previous device (S3). I called AT&T and after a lengthy call, they said I didn't need an unlock code if I was getting service OK from Straight Talk. My old APN info is still there for them along with the one I created for 'ST'. I have no way of deleting the old APN, and who knows where, or if I'll get updates from. My only other option was to get the Google Edition S4, but I payed full price for the one I got now. Hopefully the bootloader issue will get cracked before long and I can get this ATT crap off my phone for good.
Network lock
I want to share something, could get passed the first screens all the way down to the network lock menu, no sha off options.
Haven't seen any posts regarding this.
Pictures attached

Hey,
I did watch that video, but I am not sure how to get to that "Samsung Service Mode" Screen . Can you tell the steps please.
Thanks.
Ok, isnt that region lock thread just for Galaxy Note 3s? and on MF3, doesnt seem like the service menu will come up at all, so kinda curious too how people are making that work.

Hey did you guys talking about region unlock or carrier unlock?
Can you please share steps you followed, it will be a great help.
Thanks.
It's been mentioned that region unlock has had a positive affect on the Sim unlock.
However Sim unlock and region unlock are totally different from one another.I used the free unlock method when I was MDL and only used the region unlock with MF3 .will I ever really know if the region unlock worked?probably never.
I am still Sim unlocked

root ur phone and download the region unlock app on google play and done :fingers-crossed:
Again, the region lock claims for note 3... so if people say it works on S4.. why isnt it listed on the app? Would love some confirmation.

Well I know there has been at least one firmware upgrade, because that upgrade to 4.2.2 allowed me to move apps to my sd card.
BUT with 4.2.2 I cannot unlock my S4. So like I did with S3, I want to downgrade it to unlock.

I'm assuming you want to try one of the free unlock methods? I'd stay away from them. You're only allowed so many attempts, I think it's 5, and then you're screwed and it won't let you unlock.
If you're going to buy an unlock or get it from your carrier then mdj or mg1 firmware will work fine

Hi, I have a samsung s4 9505. as it's a spare I decided to play arOundle with the firmware so I installed the latest stock one. Its now locked to EE. Is there any firmware / Rom that I can install without it being tied to ee. If so , where can I download it from. Do any of you guys have one. I am uk based. I have tried the unlock method that I found on the net. By keying in *#0011# but I can't get the service menu up to change it. I had a insurance claim on my other phone and that give you the choice to use whoever you want. Is there a way of cloning that one and putting it onto my s4. There both S4 9505.
Thanks
You need to downgrade your modem or possibly the entire ROM to an Android 4.2.2 version before the service mode exploit or RegionLock Away will work. Once you do that and unlock the S4, download this ROM and install it. Then you should be good to go.
Thank you for the reply, can you link me to the downgrade the rom to andriod 4.4.2 , I'm not that techy so please be gentle . Lol

I tell ya my opinion. The best you can do is unlock your device by IMEI buying a simple code coz downgrading is always one big risk.
I have tried 2 online unlocking company's but both said they can't generate the code.

I'm not sure. I will receive Sprint S6 next some days. I will update after trying this. We will know that soon.

A better way and one that worked is to use the GalaxyTools apk

Bad news, there is no any Custom ROM for Sprint Samsung Galaxy S6 and S6 Edge.
I will work around then posting results.
Hey guyz, Calling Sprint and asking them to unlock the phone for international use (your going on vacation to Europe ) is an easy way to do it.
If you can get Galaxy Tools to work for you it will also unlock your phone for international use.
I've read if your phone is post Feb 15 2015 and you own it outright it can be unlocked for US use... I don't know this for a fact so you would need to do your research... Or just call Sprint and ask for the policy details.
Hope this helps spme...
Thx!

If you want to upgrade it to Lollipop, you must install stock ROM Lollipop via ODIN. This method won't relock after upgrade ROM. Tested, confirmed
