I'm no Samsung phone expert, but isn't this what Odin is for?

From the All Things Root subforum: http://androidforums.com/behold-2-all-things-root/151936-all-things-odin-adb.html

If I remember what everyone says about Samsung devices correctly, Odin can reflash stock images onto non-functional phones. It might restore your phone, too.

 

I am an Odin dummy but I would agree. Everything I find on Behold 2 bricks netwide seem to suggest flashing the BH_Man mod to fix. Then I found out he was an active member here:

And, the stock firmware (hopefully there isn't mulitple carriers) is also linked in the OP. Luckily enough, the mod and the stock firmware APPEAR to still be active links.

So can you access download mode?

 

Seems to be some newer stuff in here also:

Also some links on last page of the thread if you run into broken ones. Luckily they're Mediafire so it appears they're still good. I'm not sure what's the best choice here tbh, just hoping something will work for you.

 

Yeah ,your phone is almost "el finito "
As a last resort ,you can try using USB jig to boot into download mode ,but I think your bootloader/nand has gone corrupt .
If it doesn't boot into download mode with the jig ,it wont recover by any possible means available .

Other than that ,You can try to resurrect your phone at a local mobile repairing shop who have J-tag riff Box . It costs anything between 10-25$ depending on locale .
That method is specially meant to resurrect download mode and it requires soldering skills .

If it doesnt work even with a J-tag then ,the phone is dead . In that case nothing short of motherboard replacement can fix it .

 

Yeah, this pretty much sums it up. Once a phone can not boot into download mode there really isn't anything you can do software wise to fix it. This occasionally happens even on newer phones with lots of support.

I am pretty familiar with Odin, but about 6 months ago I had to send my wife's Nexus S back to Samsung for repairs. It happens to the best of us.
