Exactly how do you update the DM42 Firmware?

[zeno333]

The directions mention a PROGRAM button which the DM42 does not have...So I need EXACT directions here...Including details regarding installing the USB driver....I need a complete walkthrough, thanks.

Also, do I put it in Bootstrap mode after I install the USB driver?...Someone posted directions before and said you install the USB driver, but they then did niot say anything about it being in Bootstrap mode when you launch Tools, but the online directions say to put it in Bootstrap mode when you launch the Tools program....I need answers here...there are conflicting directions here. thanks. EXACTLY what does one do it total do upgrade it...I need all the exact steps...when in Bootstrap mode or not, everything...I am asking for detailed directions, since the directions pose questions...
