Ok, so it appears that I am not so snesus-challenged after all, I was able to update the firmware and then to rewrite user data to it.

We'll see how it does now... I am going to do the little "scok" or pocket for it to avoid the "shorting" out of the contacts issue (although I am not totally convinced that it was the only issue)...

Wish me luck now.

Dive safe and thanks for all the comments (yes Mookie, you made me do more thinking and I finally figured a few things out ).
