first off, of course i have a flasher. this is some kind of cex2dex, but there must be more parameters to be changed in eEID to be able to use debug functions.
i could install the debug firmware just as a normal update from xmb. if you do it without this flag in eEID you get some error when trying. only in service mode you can force to install debug fw.
the debug functions though didn't work. i had hope to get use of the debugger but only a few options work. also pkgs cannot be installed, though i haven't tried psn pkgs.
but to find the other flags to make full debug is another (endless) try and error path...
