Flash FW to Three 3 UK problems

Hi, guys, great site, been lurking for some time now, and flashed a few K800i's before perfectly, but now ive come across a problem.

i want to flash a K800i from 02 branded to full Three UK branding so i can use planet 3 with a 3 simcard i have,.

every time i try, it comes up with th "configuration error".

ive manage to debrand ok to a std generic one fine, but not 3 uk

ive beeen using files:-
K800_R1KG001_FS_HUTCH_1_RED52.FBN
K800_R1KG001_MAIN_HUTCHISON_WI_RED52.MBN
and K800i_CDA102511_69_R24A_3_United_Kingdom (custpack)

any ideas? do i have the right files? its got me right stumped!

Any help appreciated. Cheers!

Ross.

there the right files what u useing to flash it
and are u keep the custom pack in rar/zip form as u need to

problem be the custom pack that did not match with the phone or FW...
plus if you wanted to use 3 sim card you can just unlock it using Remove SIM-lock patch generator - Top Sony Forums.
