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?

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.
