Part 1: Why iOS 9.3.5 Needs "UPD" Repos When iOS 9.3.5 was current (circa 2016), repositories like ModMyi, ZodTTD, and BigBoss were the gold standard. Today, those default repos are largely dead. If you restore a device and run Cydia fresh, you will see endless red errors. The term UPD in your search refers to updated community mirrors and archives. Because Apple revoked TLS certificates for older OS versions, many secure HTTPS repos now fail. You need repositories specifically patched for the legacy apt client on iOS 9. Key fact: iOS 9.3.5 is the final resting place for 32-bit Cydia Substrate. Modern tweaks (iOS 12+) will not work, but a vibrant archive of "legacy" tweaks exists—if you know where to find them.
