what happened is i have a chameleon modchip and a solderless adapter. xbox worked fine for over a year. now i read that some new games that have xbox live update feature have caused problems. i don't have xbox live account but i do have my xbox connected to my router all the time because i ftp to it often. i recently backed up burnout3 and star wars battleground (both games i've read have caused problems), and all the sudden my xbox won't boot, but it wasn't right after i backed them up, i had been playing for about a week and then just all the sudden one day it doesn't work. i get an error 13. this happened about a week ago. i messed around for a long time, and somehow i was able to boot to a disc and i reformatted the harddrive (120g WD) and started putting all my saved files back on. it's worked fine for a week, and i couldn't figure out why it wasn't working before. well now all the sudden it is doing the same thing (i had since reloaded on burnout3 and played about 25% of the game). i can put in the original HDD and boot to the original MSDASH, but if i try to put in a boot disc (same one that has worked many times before) it won't read it. if i put in the larger HDD i get error 13 or 14. now this all makes sense if my dash on the larger HDD got messed up, but i can't even load into a boot disc. I tried reseating the modchip several thousand times so that really can't be a problem. i even tried a different modchip (xenium) and no luck. the xenium modchip led even comes on just fine so i know that there is not a problem with the solderless adapter or d0. again i did nothing physically to change the xbox just all the sudden it doesn't boot, it's like hte modchip isn't even there. has anyone come across this, or have any NEW suggestions? i've read every forum 400 times so i'd appreciate any new insight other than the standard suggestions. Thanks!
