I have done this but am getting an error message

I followed the step-by-step but substituted the K800 files for K770 ones.

K770_R8BC004_MAIN_GENERIC_VI_RED53.mbn
K770_R8BC004_FS_EUROPE_1_RED53.fbn

I opened the FAR program ran the first installs above which threw no errors up. I then discounted and added my custom pack:

K770i_1202-4418_R7A_3_United_Kingdom

I have installed this. I didn't complete the last step though the "Lighting options" as nothing was inclueded.

When I boot the phone up now it says "configuration error. Please contact your network operator or service centre.


Please help
