Network locked after flashing ParanoidAndroid 4.0

Hi
I just installed ParanoidAndroid 4.0 on my galaxy nexus and it all went well and I really like some of the new features.

After taking my SIM from my other phone (another SGN but running 4.3) and installing it in the upgraded phone I found the "SIM network unlock PIN" message on startup. This phone worked fine on 4.3 prior to flashing.

I have spent some time looking for the solution and have tried the following.
- Wiping and Reflashing ROM
- FuxkDocomoV3.1 from here http://xdaforums.com/showthread.php?t=1548210 (keeps FCing, may not support 4.4)
- Tried to get Samsung_IMEI_Unlock_v1.2.2.rar as per here http://www.youtube.com/watch?v=LiduCD32bUE, but gave up very frustrated with the website and the adds/surveys.
- Also considered trying Samsung Network/Sim Unlock Code Generator/Patcher from here http://xdaforums.com/showthread.php?t=1731931

I don't have a problem paying a bit of money for an unlock code/application if it fixes the issue. I have read that 4.4 may have some type of region lock and I am worried that this may be the problem and therefore the unlock code will not help.

Does anyone have any suggestions of what else I can try or maybe a copy of Samsung_IMEI_Unlock_v1.2.2.rar. If a unlock code is required, any recommendations of which site I should get it.

I would first try out flashing a known stable 4.3 ROM first and see if the issues persists. If it still does, go and reflash factory image and see if its still SIM locked.

Well I flashed the stock 4.3 jwr66y and still the same problem, network locked. Where to from here?

It seems I got lucky.
I contacted a few service provides either by phone or on their website until I found a record of the phones IMEI. Luckily it turned up on a provides website that supplies unlock codes.

I applied the code and it worked although I am pretty sure the message displayed after entering the code said something about unlock unsuccessful. I did a factory reset and it still seems OK.

Hopefully it remains unlocked now.

Thanks for the suggestions.
