I updated to JB 4.1.2 firmware ( I9100XXLSJ ) yesterday and my phone kept complaining about Network Lock. Which i have fixed in few easy steps.
We assume that your phone is rooted ( I may add a tutorial on this later)
1. Download and Install this given apk ( GalaxSimUnlock.apk )
2. Once you open the apk it will show you the current status of your phone.
3. Click the white bar at bottom.
4. If asked grant the root previlages.
5. It will inform you about the network unlock. ( Now simple restart the phone) .

Great! Thanks
Awesome man.Fu**ed my mind up for 4 hours on the internet to search for this particular software.Thanx a ton.

Wow.
Hours of fruitless searching resolved in about a minute.
Upgraded my Galaxy S2 to Jellybean 4.2.2 (Cyanogen Mod 10.1) and lost my unlock.
Followed the instructions on here and am still shocked at how simple it was.

how you install this .apk in your phone??? pls haelp me
use appIntaller from georgy house. ( From Google Play )
once you open the app. It will search for all the apk on your sd card. ( Allowing you to install/ uninstall/ remove apps)

You saved a life man with this post.. really.. I bought a second handed sim locked s2.. mom was about to kill me.. now it works smouthly.. THX MAN!!
you have to root the phone. (as the application need to have root previlageis to do its job, overwrite some stuff in OS).
In short once you root the device the application should work.
THANK YOUUUUUU

Hi mate!
I just tried this software on Galaxy S 2 - locked to T-Mobile UK with stock firmware 4.0.4 - software reported that my phone is not supported so I've tried on my risk :) AND ITS WORKS!!!
SO far after 4 days of Google search and testing various methods including dodgy you tube videos where people only stealing your time and money :0 GOOD JOB!!! will link your blog on my facebook and forums I use :)
good to see that the solution is still working.
When I open up the app all I get is undefined on all and also "unable to read nv data" is this still able to unlock the phone?
give it a go. (if your deviced is rooted)
Just unlocked my SG2 in less than 2 minutes. Now beat that T-Mobile Uk (EE)!!! Thanks dude for the wonderful tool.
Wow!! It works!
I've tried loads of "so called" network unlockers and none work.
Only this one shines through.
Tried it on my Galaxy S2 using NeatROM JB 4.2.2
Guys, do you know how to get this oe similar program in US? We are not allowed to download SIM 2 unlock thanks to our government! But we can still root:))
Thank you so much. I can't explain my feelings, but after 3 days seaching on internet I found this way and it's work!
