trying to unbrick my W810i

[simox]

The problem is here:

can't open file "C:\Program Files\SEtool2lite\rest\R4EK001_CXC1250316_GENERIC_ HN"

You need to make a rest file for your MAIN firmware with SETool_folder\make_rest\ssw2rest.exe and copy it to rest folder.

Or you can use XS++ instead of SETool2 Lite...
