hk 635 upgrade?

[ndangrd]

i bought another hk 635 & the firmware version is 4.05. the new firmware appears to be 5.12. anyway, do any of you have suggestions/advice on the best way to attempt this upgrade. the last time i tried it on a different 635, my computer froze & the 635 was stuck in stand-by mode.

also, does anyone know what the differences in the firmware versions are or where i could find this. i couldn't find it on hk's website...

im pretty stupid in navigating websites ...

can someone post a link to the firmware page on HK?
also like ndangrd said, anybody have the differences in each upgrade?
