Great
I am Sure one can Buy the Adapters for the Flash.....

Aside from that You POUND in the Fact that if One removes the Heat Shrink Tubing From the Tool It Voids any Warantee, And then you Post This. LMFAO

Next Question someone will Ask Is, IF Pin 14 Is Not Used, And removing the Heat Shrink Tubing Will Void Warantee, WHY Done you Provide the USBJTAG NT With the 3.3V MOD to Pin 14 Already Done ?????????????

You opened Up a CAN of WORMS Buddy.

That is not standard EJTAG spec. It might kil your target if 3.3v is applied internally.
This mod cannot be used directly on DCT700 or any 14 pin JTAG.

This has its advanages But For most Users In Circuit Programming is the Way to Go. Most people won't have the Skills or tools to Peroperly remove the SPI flash and ReMount after Programming.
However this Information is Usefull for those looking to Program the SPI flash Before Mounting it To Replace a BAD SPI Flash,With the Proper Tools of Course..

Wink wires

that is a lot of wires to solder with shaky hands.
I have loose blank chips and a receiver with a chip soldered in.
Either way would be fun.
For the openbox s10 I would start the rs232 loader which puts the receiver to sleep, then attempt in-circuit programming.

If you just program SPI flash, you need to make sure hold pin is steady, float around is not good.
