stepped back ApTV 2 to 5.3 via iTunes restore w/USB mini

will I still be able to JB with FC .96 or am I baked?
Thinking I’d sell it JB’n while it’s still of value to someone.

Since its still signed currently yes:

Just run Seas0npass and let it do the rest for you.

Learn how to use DFU properly if you don’t already:

do not skip step 6! By skipping it you are not finishing the JB!

thanks for the additional info.
