    Hi All,

    I want to use 4GB SDHC card with my Treo 650. I used the SDIO-sdsd.prc mentioned at:

    I inserted the 4GB SDHC Card but my treo 650 still shows 1.7 GB total.

    Reading the forums, I found that I need to update the ROM using the Rom tool. I followed the step by step process in the pdf. My Treo goes into Bootloader mode successfully, but the romtool fails to connect with my treo (in rainbow colors). Rom tool says "phone found, waiting for bootloader". When I exit the rom tool, I get the following error:

    An error occurred. Hit Ctrl+C to copy this error to the clipboard.
    Object reference not set to an instance of an object.

    at RomTool.PhoneInterface.<>c__DisplayClass7.<CreateReaderThread>b__6()

    at System.Threading.ThreadHelper.ThreadStart_Context(Object state)

    at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)

    at System.Threading.ThreadHelper.ThreadStart()

    Few more things based on other threads:

    1. I tried restarting the laptop. Doesn't help!
    2. I am using the HotSync cable to connect my treo with my laptop.
    3. I used mmty tool
    to create new connection using "WCEUSBSH001" but the tool crashes.

    I would really appreciate for any pointers.

    There should be no password set on your device. If you have one, it won't connect. Go to Security in your Treo and remove the password.

    Secondly, remove the SD card from the Treo before you connect.

    Hopefully, this will solve your problem.
