Hello,

I have a Samsung Galaxy S2 that is SIM Locked to UK's 3 Network. I was able to root the phone and unlock it when I was running on Android Gingerbread, and worked well even after updating to ICS till a couple of days ago when it started asking for SIM unlock code.

I've tried reseting the phone to the factory definitions and reeintalling an unsecure kernel so I could run Busybox and the Samsung S Unlock apps that I've used the first time I've unlocked the phone. Even tried installing a diferent region Kernel but it just resulted in a number of crashing processes.

Also locked at this thread but I was unable to locate the nv_data-bin file on my phone even with android commander.

Can anyone give me some hints on how to unlock this phone?

Thank you in advance

PS: Kernel version is the XWLPT

Your can try Galaxy S Unlock from Market . It's ok for unlock your simcard .
But look at your sdcard if you've got some files efsbackup.tar.gz . If not , your have no backup and sorry i can't help you .

thanks, but it i dont have any credit card setup in google account, in fact i dont have any credit cards.
is there any other options just using files unlocked before i flashed this rom?
this phone was unlocked using galaxy s unlock by helroz, there are galaxy_s_unclock folder in my root sdcard.
can i just use that file only to unlock my phone again?

The older version of Galaxsim Unlock worked for me.

found here:

The carrier is often not a great help and they sometimes charge a fee for unlock code. Plus the waiting time is frustrating.
I contacted support where i bought my phone and they provided no help.

It seems my phone was originally locked to O2 telefonica even though I bought it "unlocked" online. I suspect a lot of the grey imports have this problem as they temporarily unlock it and then sell it as unlocked. If you need help unlocking it again they're not interested...

I will stick to only Google branded/play store from here on, then I wont need to flash (or wait until the phone is obsolete) before finally getting an update via Samsung.

my phone GT-I9100 on XXLPQ and CF-root

Yes your right.Its free for xda users,but its a "paid service" if you get it from play store.

Ya I know I bought it from the play store to support developer but op says he doesnt have a credit card. Which is why gave him the link to the thread on xda where he can go and get it...not sure whats stopping him.
