Re: Unlock i9305
Here is a tutorial I found in a quick Google search:
http://www.mobilepoint.us/2012/12/sa...edure.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But it is most likely outdated so I recommend going onto the official site of Z3X ( http://z3x-team.com/category/news/)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,

Quote:

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.

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 ?)

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