K610i configuration error

After much help from Forum members I have applied an unlock patch to unlock my phone.
To get to this stage I have
Flashed new Main Firmware K610 R1KG001
Applied Unlock Patch from SimLockPatchGen
This all worked fine
Now I now have
"Configuration error. Please contact your network operator"
From reading other posts I think I need to flash a custom pack. I assume I need to download one for my phone, K610, for Europe2 ( same as my FS file), but there appears to be two versions, R4A and R5A.
Does it matter which one I use, and am I correct, or is there another solution.
Thanks in advance
