then the screen showed "error : update error". ok not to worry, let's check the documentation. no mention of error code 266. hmm... try running the update again, same error, and i seem to well and truly stuck in the boot loader screen, rendering my pda phone useless. it's midnight and i'm starting to feel pretty panicky at the thought of losing my touch. i tried googling and found some references to checking the usb connection, which i have already confirmed is working fine. i send off a query to htc support via their website asking for help.
the response i got the next day said:
The multi color screen is called the boot loader screen. The white bar on the bottom should say "Serial" if its not connected to the computer. On Active Sync on the PC go to File > Connection Settings and untick the box that has "Allow USB". Click OK and try to run the ROM upgrade again as per normal. If it is unsuccessful, your device has become bricked and you will need to send this off to the repair center. Our repair centers contact number is ....so, besides telling me what i already knew / had tried (and indicated as much in my original query), this response also failed to mention one little detail which i found after doing some more googling - giving the suggested solution for error 266 (Update Error - Not able to detect the USB connection) being to remove the memory card before flashing again. what this has to do with the usb connection i don't know, but it certainly worked.
i replied to htc with the feedback that "it might even be helpful to include this information in the documentation that comes with the ROM downloads, given that the use of memory cards would be fairly commonplace." makes sense, don't you think?
one day, when i'm feeling game / foolhardy, i might contemplate installing an unofficial WM6.5 ROM if i can find a suitable one for my model.
