Bricked zgemma H2

Hi,

I have bricked my H2, i had almost got it working from a boot loop and then flashed the bootloader after being advised to do so but seems to have corrupted, i now have a blank display and red light. I know i need a cypress board to jtag it but there seem to be different flavours and not sure which to purchase, id prefer a kit type that will give me connectors to solder to the PCB, my other concern is that i will be using a windows 10 laptop. I cant find a specific walk through for my model either, any pointers greatly appreciated.

ill get that done now and get back to you but im sure it was unplugged for some time but that was possibly when it was boot looping...

i left it off for three hours.. Still no dice, I have eliminated any issues with USB stick, the box display is blank and have a red light. I think I need to move onto jtagging

so..has anybody else jtagged one of these and can point me to the correct cypress board and connectors please
