After the Network Lock menu it says Command don't exist or something like that.
Help me what to do please.

All I can comment on is how I did it on mine. I don't have any other phone. Sorry.

Maybe try the UK one that I used. Once it's SIM unlocked you can put a local to you ROM on.

I followed the instructions properly. I rooted my 4.3 with CF auto root, and then I tried to flash the 4.1.1 firmware onto my phone.

Now it is stuck at the boot screen, and I'm so shocked because I did everything correctly.

I can still get to "ODIN Mode" by holding volume down, home and power, and it says:
Current Binary: Custom
System Status: Custom
Knox warranty void: 1

What have I done wrong?

Thank you.

You mean flashing 4.1.1 from 4.3 got no failure?
Currently downloading 4.1.1 version..after attempting to flash 4.1.2 it failed in Odin,due to a new bootloader

Confirmed I successfully flashed 4.1.1 and successfully unlock network.

Tnx dude!

I must say.... you are my SUPER STAR..... I have search everywhere and looked every corner of the website..... apart for paying around 20 to 40 to unlock the phone from someone... you have made my day.... I have been trying to unloack a phone that I have bought from ebay... it was locked to EE network in UK, your way of downgrading the firmware to 4.1.1 and use the code *#197328640# had worked... the phone has been upgraded wot 4.3 Jellybean, and the code does not work at all. However after down graded to 4.1.1 (as you have done) , I was able to use the code *#197328640# and unlock the phone, then I upgrade it back to 4.3 and now doing a firmware upgrade to 4.4..... the network block has ceased... so I guess the phone is now completely utterly unlocked forever....REALLY Thanks to your logical trial and error...

I must say, it took me some trial and error to reinstall the stock ROM, whick I had to use Philz recovery to completely clean up the device before I reinstall the stock rom.....
Any thanks again, and when I get a chance, I'll post my steps which had worked.

Cheers Mate,

works great
Big thanks to BorgCymru for the how-to.

Just got a n7105 that was locked on EE/Orange (UK) that had KitKat 4.4.2 installed. Followed all the instructions but used cwmrecovery (to make backup rom) and it worked great for me. Tested with tesco, 3, o2 sim and all work.

Only thing to add that after installing firmware 4.1.1, the phone went to reboot but the screen became locked on the 'Samsung' logo. I removed the battery and booted into recovery to wipe partition and wipe cache. Rebooted and all was fine.

I know you posted the original post a while back, however I purchased a note 2 7105t off eBay and it was locked to Vodafone Australia. I actually got a code off their unlocking site and of course it did not work. I then contacted their customer service and waited 4 days for a call back with a unlock code and master reset code, once again did not work and I was told to take it to a Vodafone shop and they will send it away. One again, brick wall, as the shop said, "have you a proof of purchase from Vodafone". Nope I do not so they refused to send away and told me I was,"stuck with Vodafone".

Now I want to thank you for assisting me in unlocking my galaxy note N7105T 4.2.2 with your information. It worked like a charm.

The only question I have is if I now put an update firmware from 4.1.1 will the lock come back on? I see here a couple of members said they were fine, can I get verification on this please.
