Tried to FLash DVR-105, now have a piece of junk

[Microman]

Well, I had version 1.00 firmaware, and I read and read. I had DVRFlash, and the two update files in the same folder.

I typed cd Desktop/DVRFlash
I typed ./DVRFLash -vf PIONEER R5100004.133 R5100104.133 and it started its work

it said this:

Switching drive to Kernel mode:
Description : PIONEER DVD-RW DVR-105
Firmware Rev. : 0000
Firmware Date : 00/00/00
Manufacturer : PIONEER
Drive is now in Kernel mode

Now sending the Kernel part:

and it just stayed there... and would not do anything...

finally gave up, now it wont even start the flash, because it doesnt recognize any drive.

So now I have a piece of junk.
