Dopamine 3 vs Dopamine 2: Compatibility Ranges and What Changed

Dopamine 3 is described as a rootless, semi-untethered jailbreak, like Dopamine 2. The clearest documented change is the expansion of the listed compatibility ranges. Dopamine 3 supports iOS 15.0 through 17.3.1 on arm64e, iOS 15.0 through 18.7.1 on arm64, and iOS 15.0 through 18.7.1 on A12 and A13 devices. The README also lists iOS 26.0 through 26.0.1 for A12 and A13. The supplied facts do not establish broader feature, performance, safety, or installation differences between the two versions.

Key points

  • Dopamine 3 expands the documented compatibility ranges compared with the Dopamine 2 ranges described in the supplied project facts.
  • Dopamine 3 lists arm64e support from iOS 15.0 through 17.3.1.
  • Dopamine 3 lists arm64 support from iOS 15.0 through 18.7.1.
  • A12 and A13 devices are listed for iOS 15.0 through 18.7.1 and separately for iOS 26.0 through 26.0.1.
  • Compatibility depends on the exact architecture or chip family and iOS point release.
  • Both projects are described as rootless and semi-untethered; no additional version-specific feature differences are established by the supplied facts.

Dopamine 3 vs Dopamine 2: the short answer

The main documented difference is compatibility. Dopamine 3 lists newer and broader iOS ranges than the Dopamine 2 ranges described in the supplied project facts. Its entries reach iOS 17.3.1 for arm64e and iOS 18.7.1 for arm64 and A12/A13 categories. The README also lists iOS 26.0 through 26.0.1 for A12 and A13 devices.

Both Dopamine projects are described as rootless, semi-untethered jailbreaks. The supplied information confirms a change in the documented compatibility matrix, but it does not confirm separate performance improvements, new jailbreak features, different safety properties, or a redesigned installation process.

  • The clearest confirmed change is broader documented compatibility.
  • Dopamine 3 has separate entries for arm64e, arm64, and A12/A13 categories.
  • Rootless and semi-untethered remain the relevant high-level project descriptions.
  • Exact support must be checked against the device category and iOS point release.

Dopamine 2 compatibility ranges

The supplied Dopamine 2.x project facts describe support across selected iOS 15 and iOS 16 ranges, with separate entries for arm64e and arm64 devices. Because the architecture categories have different documented limits, a broad statement such as “Dopamine 2 supports iOS 15 and iOS 16” should not be treated as universal support for every device.

The supplied Dopamine 2 information does not provide a general A12/A13 entry. Readers should therefore avoid transferring the Dopamine 2 arm64 or arm64e descriptions to other chip families.

  • Dopamine 2.x is described for selected iOS 15 and iOS 16 ranges.
  • The documented entries are architecture-specific.
  • The supplied facts do not establish a general Dopamine 2 A12/A13 range.
  • Use the relevant Dopamine 2 project documentation for the exact device and point release.

Dopamine 3 compatibility ranges

The Dopamine 3.x README lists iOS 15.0 through 17.3.1 for arm64e. It separately lists iOS 15.0 through 18.7.1 for arm64, and the same iOS 15.0 through 18.7.1 range for A12 and A13 devices.

A12 and A13 devices also have a separate listed range covering iOS 26.0 through 26.0.1. That entry is limited to those chip families and those exact point releases. It should not be extended to other devices or to later iOS 26 versions.

  • arm64e: iOS 15.0 through 17.3.1.
  • arm64: iOS 15.0 through 18.7.1.
  • A12/A13: iOS 15.0 through 18.7.1.
  • A12/A13: iOS 26.0 through 26.0.1.
  • The exact point release and device category must match the documented entry.

What changed between Dopamine 2 and Dopamine 3?

At a high level, Dopamine 3 expands the documented compatibility window. The newer README lists arm64e through iOS 17.3.1, while arm64 and A12/A13 entries reach iOS 18.7.1. A12 and A13 devices also have a separately listed iOS 26.0 through 26.0.1 range.

This comparison should remain focused on what the supplied facts actually establish. They document compatibility-range changes and describe both projects as rootless and semi-untethered. They do not establish differences in package management, performance, reliability, security, installation steps, or tweak support beyond the general rootless explanation.

  • Dopamine 3 has a later arm64e endpoint than the Dopamine 2 range described in the supplied facts.
  • Dopamine 3 adds documented arm64 and A12/A13 ranges reaching iOS 18.7.1.
  • A12/A13 devices also have a narrowly defined iOS 26 entry.
  • No additional version-specific feature differences are confirmed.

Rootless and semi-untethered: what the descriptions confirm

The official project descriptions characterize Dopamine as rootless and semi-untethered. Rootless jailbreaks permit writes only to certain filesystem areas rather than providing unrestricted filesystem access.

That limitation can affect tweak compatibility. Tweaks may need rootless-specific updates or recompilation. Sileo and Zebra are identified as package managers associated with Dopamine, but the supplied facts do not define a distinct Dopamine 2 versus Dopamine 3 package-manager feature set.

  • Rootless does not mean unrestricted filesystem writes.
  • Some tweaks may require rootless-specific updates or recompilation.
  • Sileo and Zebra are associated with Dopamine.
  • The supplied facts do not confirm a version-specific package-manager difference.

How to read the Dopamine 3 compatibility entries

Start with the exact iOS point release, then identify the device architecture or chip family. Do not begin with a broad label such as “iOS 17” or “iOS 18” and assume that one endpoint applies to every device.

For example, arm64e reaches iOS 17.3.1 in the documented Dopamine 3 range. The arm64 and A12/A13 entries reach iOS 18.7.1. The separate iOS 26 entry applies only to A12 and A13 devices and only from iOS 26.0 through 26.0.1.

  • Check the exact iOS point release.
  • Identify whether the device is arm64, arm64e, A12, or A13 where relevant.
  • Do not transfer an endpoint from one category to another.
  • Treat the Dopamine 3.x README as the authority for the current listed ranges.

What about Dopamine 3 on iOS 17.6.1?

The iOS version alone is not enough to determine compatibility. iOS 17.6.1 is later than the documented arm64e endpoint of iOS 17.3.1, so it falls outside that arm64e entry. The Dopamine 3.x README separately lists arm64 and A12/A13 categories through iOS 18.7.1, making the device category essential when interpreting this version.

This is an example of why broad searches for an iOS version can be misleading. A compatibility conclusion should match the exact architecture or chip family with the corresponding README entry.

  • iOS 17.6.1 is beyond the listed arm64e endpoint.
  • The arm64 and A12/A13 entries extend through iOS 18.7.1.
  • The device category must be checked before drawing a conclusion.

Frequently asked questions

Is Dopamine 3 compatible with more iOS versions than Dopamine 2?

The supplied project facts describe Dopamine 3 as having broader documented compatibility ranges than Dopamine 2. Dopamine 3 reaches iOS 17.3.1 for arm64e and iOS 18.7.1 for arm64 and A12/A13 categories. A12 and A13 devices are also listed for iOS 26.0 through 26.0.1.

What is the Dopamine 3 arm64e endpoint?

The Dopamine 3.x README lists arm64e from iOS 15.0 through 17.3.1.

Does Dopamine 3 support iOS 18 on every device?

No. The iOS 18 range is listed for arm64 and A12/A13 categories through iOS 18.7.1. Arm64e has a separate endpoint at iOS 17.3.1, so iOS 18 should not be treated as universal support.

Does Dopamine 3 support iOS 26?

The README lists iOS 26.0 through 26.0.1 for A12 and A13 devices only. The supplied facts do not support extending that entry to other chip families or later point releases.

Are Dopamine 2 and Dopamine 3 both rootless?

Yes. The supplied project descriptions identify Dopamine as a rootless, semi-untethered jailbreak. Rootless operation limits writes to certain filesystem areas, and tweaks may need rootless-specific updates or recompilation.
