Dopamine 3 Jailbreak: Official Project Pages and Compatibility Guide

Key points

Use the official Dopamine website named by the Dopamine 3.x README for project information and the published download location.
The opa334/Dopamine GitHub repository is the project’s open-source repository.
Compatibility must be checked by architecture or chip family as well as iOS version.
The README lists iOS 15.0–17.3.1 for arm64e and iOS 15.0–18.7.1 for arm64 and A12/A13 devices.
Dopamine is documented as rootless and semi-untethered, and rootless operation can affect tweak compatibility.

Where to find the official Dopamine 3 project

The Dopamine 3.x README identifies the official Dopamine website as the project’s website and download location. It is the appropriate starting point for readers looking for Dopamine 3 information or the project’s published download destination.

Dopamine is also open source in the opa334/Dopamine GitHub repository. The website and repository provide the clearest project context because they are the official pages identified by the supplied project facts. This article does not provide an alternative binary or a separate download link.

Start with the official Dopamine website named in the 3.x README.
Use the opa334/Dopamine repository for the project’s open-source source and documentation context.
Check that a page is an official project page rather than an unrelated page using the Dopamine name.

How to read the Dopamine 3.x compatibility ranges

The Dopamine 3.x README describes Dopamine as a rootless semi-untethered jailbreak and separates its documented ranges by architecture or chip family. Therefore, checking only an iOS version is insufficient; the relevant device category must also match the README entry.

The README lists iOS 15.0 through 17.3.1 for arm64e. It separately lists iOS 15.0 through 18.7.1 for arm64, and for A12 and A13 devices. These are category-specific entries, not a universal statement that every device on the same iOS release is covered.

arm64e: iOS 15.0 through 17.3.1.
arm64: iOS 15.0 through 18.7.1.
A12 and A13: iOS 15.0 through 18.7.1.
Match the device architecture or chip family before treating a listed iOS range as relevant.

Why broad iOS labels can be misleading

Shorthand such as iOS 15, iOS 16, iOS 17, or iOS 18 should not be read as universal support claims. The supplied documentation allows those labels only within the relevant continuous range and with the applicable architecture or chip-family restriction.

For example, iOS 18 is relevant only to the categories whose documented range reaches iOS 18.7.1. Arm64e has a separate endpoint at iOS 17.3.1. Similarly, the iOS 17 label must not be used to imply versions beyond the endpoint for the device category being discussed.

Treat the exact point-release endpoint as important.
Do not extend the arm64e range beyond iOS 17.3.1.
Do not turn an arm64 or A12/A13 entry into a claim about every device.
Prefer the 3.x README over older or simplified compatibility text.

What rootless means for Dopamine

The official Dopamine website explains that a rootless jailbreak permits writes only to certain parts of the filesystem. It also notes that tweaks may need to be updated or recompiled for rootless support.

This means rootless behavior is relevant when considering tweak compatibility. The website identifies Sileo and Zebra as package managers associated with Dopamine, but that association does not make every package or page mentioning those names an official Dopamine source.

Dopamine is documented as rootless and semi-untethered.
Rootless operation limits which filesystem areas can be written.
Some tweaks may require rootless-specific updates or recompilation.
Sileo and Zebra are identified as associated package managers.

A concise checklist before using Dopamine 3 information

First, identify whether the information comes from the official Dopamine website or the opa334/Dopamine repository. Next, confirm that compatibility details refer to the Dopamine 3.x README. Finally, compare the device’s architecture or chip family and iOS version with the precise documented range.

A page that merely uses the Dopamine name should not be treated as an official project page. Keeping the source check and the compatibility check separate helps avoid both attribution errors and overly broad device claims.

Verify the project page before relying on download information.
Use the current 3.x README for the documented ranges.
Check architecture or chip family together with the iOS version.
Do not assume that a page using the project name represents the project itself.

Frequently asked questions

Where is the official Dopamine 3 download location?

The Dopamine 3.x README points to the official Dopamine website as the project’s website and download location. Use that project page for the published download destination and related information.

Is the Dopamine GitHub repository official?

The opa334/Dopamine GitHub repository is the project’s open-source repository and is part of the official project context.

Does Dopamine 3 support every device on iOS 18?

No universal claim should be made. The README lists iOS 18.7.1 for arm64 and for A12/A13 devices, while arm64e has a separate endpoint at iOS 17.3.1. The device architecture or chip-family category must be checked.

What does rootless mean for Dopamine?

The official website explains that rootless operation permits writes only to certain parts of the filesystem. It also notes that tweaks may need to be updated or recompiled for rootless support.

Why should I use the Dopamine 3.x README for compatibility?

The supplied project facts identify the 3.x README as the authority for the current documented ranges, while the official website’s displayed compatibility text may lag behind it.
