In XS++3.1 check "Flash Main Firmware" and choose
K810_R8BA024_MAIN_GENERIC_SM_RED52, then check "Flash File System" and choose K810_R8BA024_FS_EUROPE_4_RED52, then check "Customize File System", select phone model K810, select CDA and region "EUROPE4" and press "Flash".
After flashing, you must search for K800_lighteffects.rar and Far Manager. you must upload K800_lighteffects to tpa/preset/system/lighteffect/systemeffects, by using FAR and this Tutorial. You didn't say anything about CID, so i assumed you have CID52.
