Is MF3 Cracked yet??? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Need my my phone sim unlock and can't enter the service menus. Everytime I enter 1 it resets....When is this security going to be cracked?? I just want to use my Straight talk sim on my S4

I'm guessing you're on mf3, tried the free sim unlock and managed to mess up your phone. I would suggest you try this http://forum.xda-developers.com/showthread.php?p=45359306 and get your phone back to stock and start over

Thn pay to hve unlocked thn do the aws unlock

I'm sure you can carrier unlock your S4 and allow you to use another Sim card. Try searching for it

I think you can carrier unlock for 3G data only. But I think Sprint has to give you the code, and you have to be off contract or paid up on your phone.
If you look around you will see the domestic unlock only rolls when you are on mf9 bootloader and can go back to mdc If you are on 4.4.2 the best you can do is foreign unlock after 90 days on Sprint and then they will unlock it.

it may or may not work chances are 50/50 even though you put in the att sim it takes time for att to push the updates you are better off using this guide http://forum.xda-developers.com/showthread.php?t=2663369 as long as you want to remain totally stock without root and such, but it will erase all data on your phone
Thanks for the link bro

if that didnt cure the phone not registered yet you need a new sim. ive posted that in other threads.after popping in the new sim you could reboot to see if it fixes it but i doubt it will. i had to do a factory reset to get it working.

Root and use region lock away app.
If that doesnt work, you can use safestrap to flash MDL modem and try the code method.

Unlocking with carrier provided code

My contract just expired so got an unlock code from AT&T, but it doesn't work. According to the instruction email, it won't work on a rooted device.
Does anyone have experience, if I odin to stock, would the unlock code work, and if the phone would stay unlocked if I flash a custom ROM?
Also, could anyone post the files to odin to MDL? The link it the thread that had it no longer works.
Thanks.

You cant unlock with at&t sim!!
You need tmobile sim card to unlock. If you tried already go head back to stock do unlock aim with different carried sim then flash what ever rom you want.
Good luck

Thanks. Luckily I have a Peruvian SIM card, from when I traveled, I used that to trigger the code and failed twice to unlock. I know I only have 5 attempts total so I wanted to make sure to get it right the next time. Did you tried just unrooting on your custom ROM? I'm wondering if that would be enough or going back to stop is required.

SIM unlock 4.4.4 NJ4???

Just wondering if there is anyway to sim unlock the s4 after the latest update???
Sent from my SM-N910P using XDA Free mobile app
Recently went through similar ordeal. Seems they took away the menu that allowed it to be unlocked. Luckily, I was able to get the unlock code from AT&T by submitting it online.
On my other s4, I was able to downgrade and unlock as normal. Try looking for note 4 or s5 methods as they may be similar.
