It's the same application that I used. It leads me to the galaxsim pro unlock which is a paid app. Ive installed galaxsim and after hitting unlock it says that unlocking will only be successful if I download the paid galaxsim unlock pro.

Did you download thespecific file?
The version of GalaxsimUnlock from XDA threads is free, only the play store version one is to pay

Very much appreciated. Thank you! Btw, what's the difference with your apk file than the one that can be downloaded to market?

Need help Orange PL
Hi,
I have a problem with my I9300 (Orange PL).
I'm looking for a solution on the forum but with no positive result.
I have the latest Omega rom. Voodoo and GalaxSim Unlock from PLAY store did not see the EFS files. GalaxSim from XDA writes that "Your device is unlocked" but it is not true.
Maybe I need to do as some suggest downgrade to 4.04 or 4.1?

You have probably installed one of the newer modems and you have the new EFS format. I believe that one can not be unlocked with this program. Read the thread on EFS and in case you have an older EFS you can restore that one (and also an older modem), unlock the phone and then upgrade with the unlocked EFS to the new format (by writing the new modem). Take backups of the EFS at all steps.

Thank you very much

Need to unlock - is root enough?

I've bought an S2 which is currently locked to O2. I'm on a T-Mobile contract. If I want to unlock the phone is rooting enough, or do I also need to replace the ROM with a custom ROM?
Root should be enough make sure you back up your efs folder first though
Sent from my GT-I9100 using XDA App
Root it then use chainfires app in the market. Unlocked mine in 60 secs. Just rooting on it's own won't unlock the phone
yes as they said...root is enough then use chainfire app but read the instructions well

Thanks for the pointer.
Has anyone got a link to a good copy of the ODIN exe which is required to root the S2? The zip file attached to the link listed in the FAQ seems to be corrupted (I've downloaded it 4 times and each time Winrar is telling me that the archive is corrupt).
There is a copy in my 4shared, see my sig.

Can I just confirm: are you guys UK-based? I'm in the UK and wanted to be sure that the Chainfire app was appropriate for unlocking UK phones?

Once you root a galaxy s 2 i9100 do you need an unlock code ?

Hey guys I have a question ..I recently rooted my gs2 i9100 which was locked to a Canadian mobile carrier called Rogers..after rooting the phone asks me for a unlock code when I put the sim in...I thought that rooting a phone would not require this ..anyone that can answer my question and if possible direct me to a website for the unlock code or a software I can use ...please help thanks

Root only give you admin privileges and full control of Android.
Network lock is stored outside of the system.
Try to use Galaxy S2 Unlock app.
Here's a tool: http://forum.xda-developers.com/showthread.php?t=1731931
That software requires you to put the nv_data.bin file from your EFS folder to generate an unlock code. It will patch the nv_data.bin with the unlock code.

Flash to an earlier rom until the free unlock apps get updates. Or just pay for the app.
Sent from my GT-I9300 using xda app-developers app
Then support the developer's hard work and buy the app.
i just checked the link on Google play, and the app is free
Just realized its an in app purchase, support the developer, it's only £1.60 or have someone buy it for you.

DONE
I flash with the old rom "4.0.4 too", I have perfor he flash more than one time becase i have an unkown CSC
I root again and I use voodoo APK
As of now, Gsu will patch a few files, not generate codes.
Once paid, you can use it as many times as you want, it'll be associated with your google account so you might use it with your sgs4 next year

Alright, so I had efs problem two days back. No imei and network. So I restored to stock and problem was sorted. But now if I try to install and i9100 based stock jb port, I end up with a black screen. Even other roms ported from i9100 cause the same problem. Any kind of help would be great.
