Due some flashing of my Box, I bricked it, so I needed an JTAG to restore the Boot Block.
I used a Wiggler JTAG found via linux-mips dot org.
I’ve successfully restored the box, by using the following commands:

cable ppdev /dev/parport0 WIGGLER
detect
detectflash 0x3fc00000
flashmem 0x3fc00000 rtl8186-boot.bin

I’ve used SMD Resistors and put them direct on the Pins of the 74HC244.
