Wow, haha. Why didn't I think of that.
I knew you had to ./adb so I should have known you had to do the same with fastboot. Thanks!
But, I was also only putting boot.img so now I know I need to fix that as well.
Yes, it worked! Thanks for the help, guys.
EDIT: Well, now my phone is rebooting and what not. So close haha.
Assuming you're on the old firmware, did you flash the old firmware patch after flashing the ROM?
