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
