DSM-300 s/w Update, yes or no

[lotharjt]

Hi Chuck,

I've reviewed the update procedure for the DSM-300 using the E-series Classic MFD. One statement in the instructions is rather striking:
"If a Bootloader Update is part of the download, this must be done first before the Software Update. Please note it may hang at 50% and not Complete to 100% and may show Failed."

It's not clear what this means. How does one tell if the Bootloader Update will be necessary? By saying "it" may hang, is that a reference to the Bootloader software? Whatever the reference of "it", what should one do if it does hang or shows Failed?

Please clarify.
