Hey guys, I had been on the hunt for SP10 Recovery files myself and this was the first thread that I had come upon, which was a bit unnerving at first. I quickly realized however, after some searching, that perhaps why people aren't replying with the links are because they are already on another thread from Nov 2016, and those people may have since moved on to different rigs. Either way, here is this (https://bitcointalk.org/index.php?topic=521520.msg16939482#msg16939482).

I found this most useful. Thanks to  wh00per for having the links in one place, and thanks to thejudge72 for pointing it out.

Provided these instructions (http://www.spondoolies-tech.org/blogs/technical-blog/tagged/recovery-sdcard.html) are still valid, I may have a working SP10 yet...
