Hi everyone,
Just to confirm that this approach works. A power surge killed off my beaglebone (no blue light on it). I bought a Rev.B on Amazon (it is cheaper than Rev.C and the only difference is the amount of onboard memory).
Booted up the new BBB and checked that it works: connected the power through USB cable, accessed the web-interface.
Then I shut it down, inserted the SD card with S2 image. It booted immediately from the SD card - no hassle.
After that, I inserted it into the S2 and it works flawlessly.
Good luck everyone!
Awesome. Glad to hear it's working for people.
