resurrected XO-1.5, died again

[Yioryos Asprobounitis]

I do not know for how long the "toasted" [1] XO-1.5 boards worked but my "oven baked" [2] board died again after 8 months of daily use and a guestimated 400+ hours.
I do not know if this is long enough to justify the process (roughly half a school year worth, I would guess), but I thought to record it just the same.

The XO-1.5 is by far, my favorite of the 3 models I have (1, 1.5, 1.75). 
Does it make any sense (safety considerations aside) to retry it?
Any experience on that?
Thanks
Yioryos.
