djape84 brings up a good point. if you had a brown phone, u needed to change it to red before flashing with "red" files.

also, if you used XS++ with your w810i, the custom files should already have been in the drop down list in FSX.

if your version wasn't there, then you should have unzipped our custom files, and put in the directory "own_custpack/tpa/preset/custom", where "own_custpack" should be in the same directory as XS++
