Hi, I have a Samsung galaxy S3 GT-i9305 which is locked on EE, United Kingdom. Can someone help me to unlock it for free. I don't want to pay for something that can be done for free. I am on rooted stock Jelly bean 4.1.2. Another thing voodoo galaxy S3 Sim unlock and all free unlocking app on Google play doesn't work and also these instructions doesn't work cause the last option is not available.
Can someone help me please?

Follow these instructions to unlock your phone. It worked for me.
Edit 19/02/16 I just tried this trick on a friend's I9305 right now, and it worked fine. Don't know why you guys are getting problems downgrading, I was able to downgrade from 4.4.4 to 4.1.1 without a hitch.
First you need to downgrade to Jellybean 4.1.1.
Download the 4.1.1 firmware from the link below or find another one on sammobile
It is the stock 4.1.1 for S3 GT-i9305 (LTE) United kingdom (EE)
I got the firmware from http://sammobile.com/

there's also another link at the bottom of this guide
Boot into download mode, flash the downloaded firmware through ODIN or Mobile odin if Odin fails.
Here is instructions on how to flash the firmware with Odin http://xdaforums.com/showthread.php?t=1671969
Then use these instruction to unlock your phone.
Put a different SIM into the handset.
Turn off the handset and switch it back on with that SIM inside.
Go to the dial pad on your phone and then type in *#197328640#.
Head over to the Main Menu of the device > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > and wait for around 30 seconds.
You should then head to Menu and choose Back, where you will come across the Network Lock. Choose [4] NW Lock NV Data INITIALLIZ.
Enter *#197328640#.
That's it your phone is now unlocked. You can use any sim card.
You can update, Root, flash custom and stock rom and everything you want. It will stay unlocked
This is the method I used to unlock my phone. I downgraded from 4.1.2 (the latest at that time) to 4.1.1.
Feedback is always appreciated. Do comment whether it worked or not for you. There's an amazing community here ready to help.
