Thanks for the info, Marcus. However, seeing that Jason went through this last year with a couple of N210 he has it would seem unlikely that all three of the N210 are broken. That being said and considering what you jus said it seems that I should’ve been able to find some version of UHD that will successfully communicate with the firmware and fpga images stored in the unit; I have not, using UHD versions from 3.9.0 to 3.14.0.
I wanted to try with even earlier versions of UHD but am finding trouble in utilizing UHD v3.4.0 (earliest version I could find) as it seems that “prebuilt” v3.4.0 needs only Ubuntu 10.10 or 11.10 which so far I’m not able to successfully install and run. Seems we’re running out of option on this one so the Deep Space Exploration Society, who I’m trying to help with this, may have to come to grasps with the notion that their N210 is a true brick.
