    If your gps is 13xx or 14xx, turn on the gps and touch the battery icon until the gps shows gps information.
    Then, connect the usb cable.

    I think you use GUPDATE method, right. You need to force the gps to be mass storage mode.
    I think this link will help you resolve this problem.

    Well got into the pre boot mode and used updater.exe to flash my original saved rgn. And the device is bsck to original.
    I do not have a GUPDATE file on the device i deleted that before.

    I used rgn tool to load the TH gdc and then replace the original boot from my device.
    I then flashed it usong update.exe but then it stuck again in the boot and reboot.

    What am i doing wrong. My devie is a 1490 KP1

    Please let me know if gps shows "software missing"?
    Also, did you change hwid for the firmware path to your original hwid?

    1. Turn the device off
    2. Touch left top side of the screen and keep touching it.
    3. Push the power button and the garmin logo will show.
    4. insert the USB cable
    5. Drag your original RGN file to updater.exe

    now you should be able to select USB in updater.exe and be able to start flashing.
    you can now release the left top side of the screen.. this worked for me

    I opened the GUPDATE.GCD from Thai 1460 3.00 with region tool I changed the boot to load my original boot 5.00 and override the HWID to 972. Then I save the GDC
    I upload it to the .system folder and after restart it starts flashing but same result stuck again to garmin screen.

    Now reflashing the original firmware in preboot mode and everything back to normal what am I doing wrong?

    I have found that problem before. So I update my GPS by the .RGN method instead.
