Quick Answer:
The most effective and up-to-date method (as of August 2025) for jailbreaking iOS 15 through 16.5 on an iPhone 8 Plus (and other A9–A16 devices) is by installing AltServer, then AltStore, then TrollStore, and finally Dopamine 2.0. It's a perma-signed, semi-untethered jailbreak—open Dopamine and tap Re-jailbreak after any reboot.
Why This Method Is the Best as of August 2025
- Wide iOS Coverage: Dopamine 2.0 supports iOS 15.0 to 16.6.1 on A8–A11 devices, up to iOS 16.5.1 on A12–A14, and up to iOS 16.5 on A15–A16 devices.
- Permanent Sideloading: Using TrollStore allows Dopamine to never expire, unlike AltStore-sideloaded apps.
- Semi-untethered: You simply tap Re-jailbreak after a reboot — no computer needed each time.
- Rootless Jailbreak: Compatible with rootless tweaks and supports both Sileo and Zebra as package managers.
- Community Endorsed: This method is the one consistently recommended by jailbreak developers and power users.
