Here is a tutorial I found in a quick Google search:
http://www.mobilepoint.us/2012/12/samsung-galaxy-3i9305-unlock-precedure.html?m=1

But it is most likely outdated so I recommend going onto the official site of Z3X ( http://z3x-team.com/category/news/)

Hi,

1. Start the phone WITHOUT SIM card
2. Open the phone application and enter the following code: *#197328640#

3. Then go in the following menus:
Main Menu [1] UMTS

[1] Debug Screen

[8] Phone Control

[6] Network Lock

Options [3] Personal SHA256 OFF

On this screen, do nothing. JUST WAIT ABOUT 30 SECONDS.
Then go back by pressing the Menu button (touch left of Home button) then select Back

you are in [6] Network Lock
then select [4] NW NV Lock Data INITIALLIZ

On this screen, do nothing. JUST WAIT ABOUT 1 MINUTE.
Then restart the phone.

4. Now your Galaxy i9305 LTE S3 must be unlocked. There is no confirmation message. The way to check is to insert a SIM card from another operator.

Before doing the instructions below, please double check your phone that it is actually LOCKED by inserting a sim card from a different carrier/provider...
you may or may not leave that sim card on the phone while unlocking

Note: your phone must be running at least Jelly Bean 4.1 otherwise some of the menu choices are not present

This will not work on 4.1.2. You have to downgrade to 4.1.1, do the above, then use OTA to go back up to 4.1.2.

Doing this then following the above tut worked for me the other day.

Hi, I tried this on 4.1.2 and it did not work, can you please tell me how to downgrade to 4.1.1? I know how to use Odin and all, I just don't where to get the firmware file, (maybe from www.sammobile.com ?)

kanzi83 · Feb 19, 2013

Hi,

Choose your original firmware 4.1.1 from sammobile.com and flash with Odin

Hi,
I want to unlock my Galaxy S3 i9305 LTE bought from TMobile UK, and unfortunately Kies has already upgraded my phone to 4.1.2, details below:

Model Number - GT- i9305
Android Version-4.1.2
Baseband version - i9305BVBLL2
Build Number - JZ054.I9305XXBLL5

Now when I go to Sammobile to donwload 4.1.1, you can see in the picture the codes don't match up where Sammobile has EVRBLL1 or EVRBLL2 under CSC and I have BVBLL2 or XXBLL5.

There is no option for TMobile in Sammobile.
Can anyone please help me or guide me what should I do ??

Thanks in advance.

Dude i was in the same boat as you. I wanted to roll back to 4.1.1. to unlock my phone so I downloaded the EE version cos there are no seperate roms available for Orange or T-mob they all operate under the same umbrella (EE). I used this guide to help me its pretty straight forward:

http://forum.vodafone.co.uk/t5/Samsung-Galaxy-S3/How-to-Flash-Rollback-Galaxy-S3/td-p/1273246 (I know its for original s3 but dont worry the guide works for LTE version aswell)

Instead of downloading firmware from sammobile I used this thread to download the original 4.1.1 stock rom:

http://xdaforums.com/showthread.php?t=1942150

look for:

Product Code: GT-I9305TADEVR (4.1.1) (EE UK)
PDA: XXALI5
PHONE: BVALI5
CSC: EVRALI5
Released: 17/09/2012

Once you done that. Unlock your phone and finally use software updater via about device to upgrade back to 4.1.2. Baseband and built number will be the same as your present one. Job done! its easy and painless!

Thanks a ton for your reply, helps me a lot.

Just curious to know if you were able to unlock your phone after going back to 4.1.1 ?? As it would be pointless if we can't unlock the phone ever after downgrading to 4.1.1.

Thanks in advance.

Thanks a lot, just one last thing. The rom that you downloaded from here(xda site) is that rooted rom or would I still need to root afterwards if I want root access ??

I am complete newbie to this Andriod and still getting hang of details, hope you don't mind.

Thanks once again.

It works fine on my phone, I'm using Pandoriam ROM v6.6 - JB 4.1.2
Did you try to type *#197328640# and follow instructions anyway???

Hi,

Not working with 4.1.2 Stock ROMs (not the same menu)

The only way is to downgrade in 4.1.1
