Can you do the same with black on ground.
Don’t do this in future… the EMMC module is tied to the SoC, so it’s pointless trying to use one from another console. Also, you run the risk of burning the update fuses on the SoC if the EMMC you attached to the console was on a higher FW version, this makes diagnosis later much tricker and if you have blown these fuses, the only form of recovery on a patched unit is the TX modchip.
It’s entirely possible you have now burned the fuses in question and regardless of if the any BSOD repairs are successful you may have to contend with the above mentioned problems.
anyway, lets hope for the best 
btw I take it your using a fluke meter?
