Downgrading to JTAG compatible dash , possible ?

[Neoglicher]

Hello everyone .

I know this is really noobish question , but me and some friends are really curious about this one .

The idea is to use the CPU key that i have got using the rgh chip and build a retail old JTAG compatible dashboard , and use the JTAG wiring instead of the chip .

Can this be done ?

You can't use the JTAG hack because eFUSEs have been blown which means your console expects a higher CB version which will not work with the JTAG hack.

You can use R-JTAG (if you can find one) or wait for the CR4 XL.
