I fixed the white screen of death problem. I just used XS++ and got firmware from this current website, obviously topsony.com. I saw there was a patch coming out to fix WSOD but never found it. I got bored and tried XS++ flashing and it worked. You have to use XS++ 3.1 though. When I tried to use v1.5 it couldn't customize K510 firmware.
In XS++ flash FS first, customize fs, then flash main.
