IMPORTANT UPDATE FOR DEVICES SUPPORTED WITH NIGHTLY RELEASES

The nightly version does not have an official wiki, the main spruce wiki is being updated currrently and so it is extremely useful for basic questions about the nightly builds

🚨 Warning 🚨

• This repository is automatically generated as part of our nightly builds. It contains experimental and potentially unstable versions of our software.

• As of January, 2026 these build are targeted towards the Miyoo A30, Miyoo Flip, Miyoo Mini Flip, Trimui Brick and Trimui Smart Pro, Trimui Smart Pro S.

• The same SD card can be used for all of these devices, simply swap the card over and it will work!

Sep. 19 2025: We have updated the suggested Miyoo FW version!

All supported devices have a built in firmware updater app. Check the Apps Section to see if your device needs to be updated!

• Copy and paste this .img file onto the root of a fat32 card (blank is best!).
• Boot your device, it will show a rocket ship and reboot when it is done.

DO NOT TRY TO BURN THE .img FILE ONTO YOUR CARD! JUST COPY/PASTE IT

If using your normal card you MUST DELETE the .img file off the card after the update.

Stock will show 20250627233124 listed unded "Device Info" in the Settings tab when booted into stock.

• Unstable Builds: This repository contains work-in-progress code. Features may be incomplete, change unexpectedly, or break entirely.
• No Guarantees: We make no promises about stability, functionality, or continued support for anything in this repository.
• No Support: Issues related to nightly builds will not receive any attention. For stable releases, refer to our main repository or latest release.
• Not backwards compatible: Due to the nature of WIP builds, you will likely need to do a fresh install of the eventual public stable release. Simply using the OTA will likely break things.

• Data Loss: Using this software may result in corrupted data or loss of existing configs.
• Incompatible Changes: Backward AND Forward compatibility is not guaranteed between nightly versions. Manual updates are occasionally required.
• Security Risks: Nightly builds have not been fully tested for vulnerabilities or exploits.

There are a couple of ways to update, OTA, EZ, and manually.

OTA: Connect to wifi and run the updater app, if your wifi connection holds on this is all you need to do!

We appreciate your feedback and bug reports! However, please be aware of the following:

• Contributions targeting nightly/development builds should expect rapid iteration and potential rework.
• Issues unrelated to nightly builds should be reported in our main repository issue tracker with a clear description telling us it is for the Development branch.
• Interested in being a tester? To provide feedback and speak with the development team please join our Discord server here

Documentation will lag behind or be non existant for nightly builds.

Nightly builds help us:

• Validate new features in real-world scenarios.
• Get early feedback from developers and power users.
• Accelerate the development cycle of our software.
