Key points
- Dopamine 3.x lists iOS 15.0 through iOS 18.7.1 for arm64.
- The official Dopamine website identifies arm64 with the A8 through A11 architecture group.
- The arm64 range must be checked together with the device’s architecture or chip category.
- arm64e is listed separately from arm64 and ends at iOS 17.3.1.
- The current Dopamine 3.x README is the authority for the firmware range.
What is the Dopamine 3 arm64 support range?
The current official Dopamine 3.x README lists iOS 15.0 through iOS 18.7.1 for arm64 devices. For the older-device search category, this is the documented Dopamine 3 arm64 range.
The range should be read as a continuous interval from iOS 15.0 through iOS 18.7.1. Shorthand references to iOS 15, iOS 16, iOS 17 or iOS 18 must remain within that documented endpoint and must not be treated as universal support for every device.
- Architecture: arm64
- Associated older-device group: A8 through A11
- Documented firmware range: iOS 15.0 through iOS 18.7.1
- Current range authority: the official Dopamine 3.x README
Which devices does arm64 refer to?
The official Dopamine website identifies arm64 with the A8 through A11 architecture group. This is the architecture explanation to use when interpreting the older-device category.
The website’s displayed compatibility information may be older than the current Dopamine 3.x README. The sources therefore have different roles: use the official website for the arm64 and A8–A11 architecture explanation, and use the current 3.x README for the firmware range.
A device should meet both conditions before the arm64 range is applied: it should belong to the arm64 A8–A11 group, and its installed iOS version should fall between iOS 15.0 and iOS 18.7.1.
- Confirm the device belongs to the A8–A11 arm64 group.
- Do not treat every older iPhone or iPad as automatically arm64.
- Use the current 3.x README for the firmware endpoint.
How arm64 differs from arm64e
Dopamine 3.x lists arm64 and arm64e as separate architecture entries. The arm64 range is iOS 15.0 through iOS 18.7.1, while arm64e is listed for iOS 15.0 through iOS 17.3.1.
This distinction matters when interpreting broad compatibility statements. A claim that Dopamine 3 supports a particular iOS version does not identify the architecture unless the architecture-specific range is included.
The shorthand iOS 17 must also be read within the relevant endpoint. It falls inside the documented continuous arm64 range, while arm64e has a separate endpoint at iOS 17.3.1. Similarly, iOS 18 may be used only for a category whose documented range reaches iOS 18.7.1.
- arm64: iOS 15.0–18.7.1
- arm64e: iOS 15.0–17.3.1
- The two architecture entries have different endpoints.
- A broad iOS label cannot replace an architecture-specific check.
What rootless means for Dopamine 3
The official Dopamine 3.x README describes Dopamine as a rootless semi-untethered jailbreak. The official website explains that rootless jailbreaks allow writes only to certain parts of the filesystem and that tweaks may need to be updated or recompiled for rootless support.
The official website identifies Sileo and Zebra as package managers associated with Dopamine. These details explain the jailbreak’s operating model, but they do not expand or change the documented arm64 firmware range.
Compatibility should therefore be considered in two parts: first, whether the device and iOS version match the documented arm64 entry; and second, whether software intended for use is suitable for the rootless environment. The supplied facts do not establish compatibility for individual tweaks or packages.
- Dopamine is described as rootless and semi-untethered.
- Rootless operation limits writes to certain filesystem areas.
- Tweaks may require rootless updates or recompilation.
- Sileo and Zebra are identified as associated package managers.
How to verify an older device
Begin by identifying whether the device belongs to the arm64 A8–A11 group described by the official Dopamine website. Then compare its installed iOS version with the current 3.x README’s arm64 range of iOS 15.0 through iOS 18.7.1.
Keep the architecture label and firmware endpoint together. A device outside the arm64 category should not be evaluated using the arm64 result, even if its iOS version falls within the same numerical interval. Likewise, a general reference to iOS 18 must not imply support across every device category.
For the final compatibility check, consult the current official Dopamine 3.x documentation. The official website supplies the architecture explanation, while the current 3.x README supplies the relevant firmware range.
- Identify the device’s architecture or chip group.
- Confirm that it belongs to the A8–A11 arm64 category.
- Compare the installed version with iOS 15.0–18.7.1.
- Keep arm64 and arm64e entries separate.
- Use the current official 3.x documentation for final confirmation.
Frequently asked questions
What is the Dopamine 3 arm64 support range?
The current official Dopamine 3.x README lists arm64 support from iOS 15.0 through iOS 18.7.1.
Does arm64 refer to A8 through A11 devices?
Yes. The official Dopamine website identifies arm64 with the A8 through A11 architecture group. Use the current 3.x README separately for the firmware range.
Is iOS 18 supported on arm64?
The documented arm64 range reaches iOS 18.7.1, so iOS 18 references must remain within that endpoint and must not imply universal support across every device.
Is the arm64 range the same as arm64e?
No. arm64 is listed from iOS 15.0 through iOS 18.7.1, while arm64e is listed separately from iOS 15.0 through iOS 17.3.1.
Can the arm64 range be applied to every older device?
No. First confirm that the device belongs to the A8–A11 arm64 group. The firmware range should not be applied solely because a device is considered older.
What should be checked before using the arm64 range?
Confirm both that the device belongs to the arm64 A8–A11 group and that its installed iOS version falls between iOS 15.0 and iOS 18.7.1. Use the current official Dopamine 3.x README for the final firmware check.
