Make sure you are safely ejecting it when you remove the usb. Also, try through recovery mode. If issue persists, I'd redownload the CFW and try again.
If still, then it's probably because you don't have Toggle QA installed. Meaning you'd have to downgrade back to 3.55 first then go to the CFW you wish.
