flash a custom pack and your configuration error will be gone, just tell me what files are you using to flash and i can help you find the custom pack for your phone

the files i had used top flash are
flash main firmware:K810_R8BA024_MAIN_GENERIC_SM_RED52.mbn
flash file system: K810_R8BA024_FS_EUROPE_2_RED52.fbn
software used:x++i checked the box costomize file system and clicked phone model:own custpack
select cda and region:i choose europe_4(cda102511/101)
then i clicked flash
here is a files of the things i mentioned such as the
flash files:
K810_R8BA024_FS_EUROPE_2_RED52.fbn
K810_R8BA024_MAIN_GENERIC_SM_RED52.mbn
and the custpack
and also the backup file i got of the flash i think it is

you should use europe_2 custom pack from the dropdown list and if can't find in the list, use this files from the download section, here is the path Top Sony Forums and download the one that is mentioned below, extract it to own_custpack inside xs folder and flash it
HB1-06_Gen_CDA102568_11_R8A_GENERIC_EUROPE_2
