NEW INFO ON THIS UNLOCK!!!

After finding and having someone test it. It was confirmed working. :thumbup:

All you have to do is downgrade you modem/radio, even if your on 4.1.2! After the downgrade it should give you option 4 if it's missing from the unlock menu!!

Hope this helps with trying to get your device unlock. It's much easier to flash a modem/radio, than it is a Rom...

So now no more having to downgrade to 4.1.1 firmware. Unless the modem downgrade didn't work for you. Which in turn should work!!! ;);)

Hi guys, you can unlock you N7105 via the Samsung hidden menu. [Also works with N7100 and some Galaxy S3 (SIII) variants - NOT ALL]

#############################################

I can confirm the unlock survives ROM flashing

#############################################

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

Unlock your N7105:

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

Just dial the following keys *#197328640#

Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone... enjoy!!! There is no confirmation on the phone that the unlock was successfull.... just reboot your phone....

To test, just insert a sim card from a different carrier/provider. If the new sim card works then your phone is now unlocked.

I have done this to my other Note 2 N7105 originally locked to Orange.....

If your missing the option 4 from the menu, then Go backnto an earlier 4.1.1 on the t mobile version i did cuz the newest didnt show option 4

Try novembers releas that worked foe me http://xdaforums.com/show....php?t=1969551
