The menu code doest lead me to the Perso SHA256.
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.

Hi,

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

Edit:
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,

Dave

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.
