I had no problem with my messiah x, except I could'nt get a switch to work, so I cut all the wires after I booted to EvoX one at a time starting with A... that went flawless. I heard that making the two switches to A and C and creating to long of wires can cause problems, maybe that was why it wouldnt work...
/me shrugs
Regardless, TSOP is flashed and it is the l33ts!
