Does Onion OS run on the Mini Flip?

Yes. The Mini Flip is a SigmaStar SSD202D device like the Mini Plus, so Onion OS is supported, alongside sprigUI, Allium, Koriki and MinUI. (The A30 is the Miyoo that cannot run Onion.)

Is it spruceOS or sprigUI for the Mini Flip?

For the Mini Flip the spruceOS team provides 'sprig' (sprigUI), a lighter build positioned between MinUI's simplicity and the visual style of Onion/spruceOS. Extract sprig.vX.X.zip to a FAT32 card root, keeping hidden folders.

What do I need before installing a custom OS?

Be on stock firmware 202510011046 first (this also fixes the swapped shoulder buttons on new units), a FAT32 microSD formatted with Rufus set to 'Non bootable', and a good card reader. Then extract one OS to the card root.

Because the Mini Flip uses the SigmaStar SSD202D (like the Mini Plus), it supports the full SigmaStar custom-firmware lineup: Onion OS, sprigUI (a 'sprig' build from the spruceOS team aimed between MinUI and Onion/spruce), Allium, Koriki and MinUI. Update to stock firmware 202510011046 first, then format FAT32 and extract your chosen OS to the card root, keeping hidden folders (for sprig, .Config and .Temp_Update are required). Use a card reader, not USB mass storage. Note: 'spruceOS' proper targets the A30/other devices; for the Mini Flip the spruceOS team ships the lighter 'sprig' (sprigUI).
