I believe my coolrunner is exhibiting behavior that one would expect if it were defective. Namely, I have spent many hours trying to get it glitch, but I literally just recently figured out something that doesn't appear normal at all.
When I try to boot the chip normally with jasper timing files after flashing jasper 16 .ecc file (many many many times) I just discovered that if I switch to Slim mode prior to booting, the green light will in fact keep flashing like it is supposed to, but when it is in PHAT mode, it will only flash for one or two times and then stop completely meanwhile the xbox is just hanging and not booting. I have tried many flashers, readers, etc... My nand is ok (other than having a bad block at 49 which is causing bad .ecc write but I'm trying to also resolve that). My soldering is ok. I had this issue when my solder was not quite as nice and then I thought maybe solder was culprit but now all solder points are on (not gonna argue about this FACT) and much cleaner and I have the exact same issue.
So I'm left with two possibilities...chip is not right because it just stops attempting to glitch after 2 or 3 tries (usually just once), or .ecc bad write is culprit.
I also forgot to mention that I had this exact same problem in another jasper with this same chip. I just thought the jasper was weird so I tried a different one. Different xbox, same chip, same problem? All signs point to defective coolrunner.
