I’m wondering if it’s possible to downgrade via the emmc reader. Is my plan nonsense? Got a bricked sync module with black screen.

Old SYNC Version: 3.0.18025

New SYNC Version: 3.4.21265

Do you have a error message, if so what is it?

Yes it’s possible but we won’t discuss the details here in public.

Unfortunately for legal reasons i won’t discuss jail breaking and eMMC flashing… its not technically illegal but it’s something i’d rather not even go in to publically.
