Do u have RGN file , please provide to me . thx u very much.

I think you must not use the US 3.00 but must use the original one. Have you sved the orginal GUPDATE.GDC that was on the device? if so you can open that in RGN tool and save it to a RGN file and use that to flash.

That is what helped me to unbrick it.
But still no luck for me getting to Thai version
