so about two or more years ago when i jtags were getting popular i got one but they didnt give me anything else besides just the console (no nand or key stuff). but after a while i wanted to update the dash, and didnt do it right or skipped steps so now it doesnt boot up. i tought maybe using my nand-x i got forever ago would help and that i would just put in a new nand to replace the bad one.

method i had done was replace my nand?? with another "updated" one (which was what the tutorial told me to do) and restart the console.

so my question is, is this fixable, am i screwed regardless and if fixable how can i go about doing this?

not sure what other info i should include but..
