theres a very good reason most people are saying the 29 wire chip is your only option, because it is
the TSOP fix bios are specially made, just any old hacked bios wont do the trick, and no TSOP repair bios were ever made for 1.4/1.5s, so your out of luck, sorry, best thing to do is just get a modchip and leave it in
That's the piece I was missing(or having trouble getting through my thick skull)...thanks for the info!
I've since learned that my trouble(s) are not all TSOP related...the problem XBOX has/had a DuoX2 already in it...I thought the TSOP & chip went bad at the same time - based on the symptoms. (chip disabled I'd get green ring, eject, looks like working properly, but no video; chip enabled I'd get the 3 reboots then frags)
Yesterday I dug in and did some more trouble shooting...was preparing to do a hot swap flash of the chip I suspected to be bad, but, I decided to just test the chip first, and it was fine. Then I re-tested the problem XBOX with no chip installed, and I got the coma console symptom...put the chip back in, still 3 reboots and frags. What a PITA. Anyway...thanks for the help!
