Hi, I Have A 301-13 Single Tsop I Erase The Flash And Now It Will Not Let Me Write The New Flash. This Is The Messege I Get. The Flash Codes Returned Not Recognized By Jkeys. Mfg/device Codes Returned Are Ffff/ffff (jedec) And Ffff/ffff (flashfile) And I Have Ground R79 And Have The Vid Mod On.

sounds like you cut ther power off before you got thru, sometimes it happens anyway to get that nag.
Make sure your jtag is grounded as well as the r79 ground.
The kind I use I ground to the case from pin 18-25 that should be crossed/grounded somewhere in the jtag.
Keep trying it will pop up the numbers. Sometimes opening another jkeys to have two running at once causes the ird to be in boot mode long enough to get it to work.
