Thanks for everyone's recommendations. I went ahead and ordered a Pixel Mago, it arrived yesterday. Looks great overall, my issue is that I am unable to connect it to a PC to flash new firmware (which I need to do in order to enable S1/S2). The device is not recognized by Windows, Code 43 in Device Manager. I've tried on 4 different PCs/ laptops, Windows XP/ 7/ 8.1, same result everywhere.
More details in the screenshots attached.
Thoughts? Has anyone encountered this issue?
Edit: The issue was that I did not have OK pressed on the flash when attaching the USB cable. My fault.
My next issue is that the latest firmware won't flash, Firmware Error 01 -- apparently I got a X650C, not a Mago. Still S1/ S2 works as expected! I am attaching the original firmware in case anyone needs it.
