I just managed to flash my H1x0+CFMod+RTC target with the bootloader in SVN.
It seems that
this bug has been resolved for the CF cards available to me.
As far as I know this was the last blocker bug for a new bootloader (v7) release. (am I wrong about this?)
Could the devs please take a look at the BL code and could some brave users test the bootloader currently in SVN to see if it works.
Once that's done I would suspect it would be the very last bootloader for the H1x0 targets released. (putting it to rest)
CAUTION: Please make sure you know what the hell you are doing as this sort of thing can BRICK your player. Seriously.
It works (so far) for me but I had a spare unit and was willing to take the risk.
