Quick Answer:
As of August 2025, the most reliable method for jailbreaking iOS 15 through 16.5 on iPhone 8 is by installing AltServer, then AltStore, then TrollStore, and finally Dopamine 2.0. The result is a semi-untethered jailbreak that remains permanently installed via TrollStore. After a reboot, you simply reopen Dopamine and tap Re-jailbreak.
Why This Is the Best Method as of August 2025
- Wide iOS coverage: Dopamine 2.0 supports iOS 15.0–16.6.1 on A8–A11 devices (like iPhone 8).
- Permanent installation: TrollStore ensures Dopamine never expires.
- Semi-untethered: No computer needed after setup — just re-jailbreak from the app.
- Rootless and stable: Works with Sileo and Zebra for tweaks.
- Trusted workflow: This exact flow (AltServer → AltStore → TrollStore → Dopamine 2.0) is currently the standard jailbreak method.
