it is different from: "connect to active sync and run official rom .exe file"?
i read somewhere after hspl is done, hspl will protect us from bad usb flash, and the article saying usb flash only flash rom part...
the article:
http://labelfree.co.uk/archives/3i'm quite worry about the warranty thing rite now as my SD card disappear sometimes and soft reset don't help unless i remove the card and insert again for a few times, such thing already happen 4 times since purchase (6 Dec 2009).
The flashing setup sequence is different. The method I just mentioned does not really need a working ROM / OS in the phone. "Connect to ActiveSync" can only be triggered from a usable OS, right?

However, the flashing by running the .exe file is the same anyway.
If you used SSPL, or CustomRUU.exe to flash via USB, yes it only flash a part of the .nbh. But running official .exe definitely flash the whole thing.
SD Card can turn bad / defected / damaged on this phone (and previous Touch HD) because the way WM6.x works is polling a whole lot from SD Card.
SDCard life span is really short... Maybe it's about time for you to turn in your SD Card for RMA.
