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





Note: your phone must be running at least Jelly Bean 4.1.1 (if 4.1.1 does not work, try 4.1.0) 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.....


========================================

Do this procedure AT YOUR OWN RISK


========================================

To those who were able to unlock their phone with the method above, can you please post in the thread and let us know which phone model (N7100 or N7105) you have, Country and Network/Carrier your phone was locked to...... and if I have saved you some cash, please click the Thanks button or the Donate button on the left just below my name to buy me a can/bottle of Heinekken, Quilmes, Budweiser, Fosters, Tiger, Stella Artois, or San Miguel :cyclops: ...

========================================

NOTICE:

To those having "Conditional Call Forwarding" pop up message or similar pop ups appear everytime you make a call (but they disappear within a few seconds), this is normal with an old sim card, or when using a ported number. There is no restriction to calls or internet or whatever. This is confirmed by my provider when I walked in and asked them about it. They even showed me one of their sample Note 2's and S3's having the same message.


========================================



I have mentioned in my old thread that there was a pop up message that says "Conditional call forwarding active" everytime I make a phone call using another SIm card that the phone was not able to use before unlocking.

I can confirm that this was due to my Sim card. It is a very old O2 sim card that I have used for years. I have tried that Sim card on another factory unlocked phone (Galaxy i8160 bought from P4u) and it had the same message.

That's really good to hear!!!:good: thanks for letting us know...

No problems. I did the steps did not work. Did them a second time, looks like it worked.
Used a verizon LTE sim, but they are a CDMA carrier. First time I tried the verizon sim asked for unlock code. Tried steps again and second time it did not calk for sim unlock code. I got signal but the notification bar still said searching.

just unlocked my at&t phone for free! Thanks OP!! Tested by inserting my old vzw lte sim. Before unlocking I got a pop up asking for the unlock code after putting in the vzw sim. After going though the steps it no longer asks me for the unlock code! Success!!

Hmm, this might open some very interesting options ...

...

Hmm, this might open some very interesting options - one of them being that the Samsung private key was somehow compiled into the modem tool inside the ROM; I wonder if that might be extracted from there and if that is Samsung-wide or just N710x-wide; what I do not doubt so much is that if that works so well then the next official ROM will remove it - but if I am right about the key it will remain valid so tools based on that could be made :good:

Thanks.

Op you are legendary, can I ask how you discovered this? I'm interested in finding the other hidden codes for the Samsung LTE phones.

Work for me on n7105 from Orange, however the menus did not behave in an intuitive way. It might be worth explaining what happens/what to expect with your details.

Has anyone tried putting the lock back on? Is it possible?

Also do you have any credits to share, I like to know all the people who helped - after all; networking is the key to success.

Again, legendary. Thank you.

No problem. I just found out about the secret code somewhere on xda, but it was for another topic I couldn't remember. But I never read about it being able to unlock the phone. I just carefully played with the menu and accidentally found about it.

I have not tried putting the lock back on.... who knows we cannot unlock it again... if you want to try it, feel free and please let us know, but for me, I will not:D

edit:
what do you mean by it did not behave in an intuitive way?

Did a search and there's a plethora of codes here

    It seems that 4.1.1 it was there, but they removed it in 4.1.2 (just last week) -- and, naturally, I only decided to travel to the US (and hence looked for unlocking howto) after I upgraded ;)

    If that's the case, obviously Samsung is taking out this option. If so, like BajanMan said, flash previous version using ODIN and then unlock your Note 2.

    Speaking of Previous Version, you can find previous Firmwares over at SamMobile. It seems you are in Luck. They have KIES Version of 4.1.1 for your NOTE 2. This should be walk in a park as you don't have to use ODIN. Just use KIES to go backwards. Unlock it and then go back Forward again.

    Kindly hit the Thanks button if this was useful.

    Hey guys, I just wanted to know is this a permanent unlock. I mean if I go back to stock will it reset my sins as well? Thanks

    Sent from my SGH-I317M using xda app-developers app

    You need to go to church to reset your sins, not stock! ;)

    This is really GREAT NEWS ...

    Have anyone tried to see if it still works after the FACTORY RESET.

    I did a factory reset on my AT&T model and the unlock was still intact!

    Can anyone confirm that this is a full sim unlock?

    I have tried 3, O2, giffgaff, and an Asian roaming sim and the phone have signal and does not prompt for network password like it did before unlocking...
