Sup M3 Custom Firmware [patched] -

Custom firmware can greatly extend a Sup M3’s capabilities but carries real risk. Follow device-specific guides closely, make backups, and prefer well-documented community builds.

Because of this hardware fragmentation, there is no "one-size-fits-all" firmware like OnionOS or ArkOS . A firmware build designed for one M3 might "brick" another if the screen driver or pin configuration is slightly different. Popular Community Efforts sup m3 custom firmware
