Usage Guide

Requirements

iPhone 6s or newer

iOS 13.0‑17.2.1

Safari browser

No computer or additional app needed

Step‑by‑Step Process

Open the official site 34306.lol in Safari.

Tap the "Go" button to start the exploit.

Read the security warning and click "OK" to continue.

Select a function from the menu (e.g., Load .dylib tweak, Install TrollStore helper, Enable FLEX debugging, Respring).

If loading a .dylib tweak, choose the file from the Files app, confirm, then respring to apply.

Main Functions

TrollStore installation for iOS 17.0 and earlier (also works on iOS 16.6.1 and earlier)

.dylib plugin injection into SpringBoard without Cydia/Sileo

Status‑bar customization (date display, widgets)

FLEX debugging for developers and advanced users

Additional features: non‑destructive reboot, flashlight shortcut, dylib adjustments

TweaksLoader Extension

The TweaksLoader plugin by iAldazActivator adds system tools (terminal, file manager, device info), home‑screen tweaks (dock animation, custom corner radius), battery tweaks (icon style, remove 80 % charge limit), notification customizations, lock‑screen layout edits, Dynamic Island modifications, and other utilities.

Safety Advice

The tool is in early development; some functions may be unstable.

Use only for testing; wait for a stable release for production devices.

Back up important data before use.

Obtain the tool only from the official site (34306.lol) and the GitHub repository khanhduytran0/coruna .

Understand that jailbreaking reduces system security.

Comparison with Google‑Exposed Coruna

Google’s Coruna: malicious spyware tool, passive infection via malicious sites.

Jailbreak version: legal tool for iOS customization, user‑initiated download.

Security: Google’s version is dangerous; the jailbreak version has been cleaned.

Conclusion

Coruna represents a major iOS jailbreak breakthrough after two years, supporting the latest iOS 17.2.1 and offering a PC‑free, web‑based exploit for convenient plugin injection. Because it remains early‑stage, users should exercise caution and await a more stable official release.
