Raritan DSX8 - possible to "un-brick" ?

[vom513 <vom513 () gmail com>]

Sorry for posting to the list, not sure where else I could ask this…

Anyone have experience with these ?  This is the older / EOL DSX serial console product.

I have a DSX8 that seemed to happily take a firmware upgrade, and after boot hangs at a specific point in kernel output 
every time.  

I opened the case and as expected everything is soldered (no CF card or anything “easy”).  They didn’t seem to put any 
kind of boot loader / rommon on these, so I’m not even sure if it’s possible to unbrick.

Replies off-list highly encouraged as I don’t want to contribute to off-topic noise etc.

Thanks.
