TrimUI Brick Pro — Custom firmware

Quick answer

Button combo

microSD swap(keep stock card as backup)

Steps

  1. 1Wait for a CFW build that explicitly lists the Brick Pro before installing.
  2. 2Use a fresh microSD/TF card so your stock card stays as a fallback.
  3. 3FAT32-format the card and extract the CFW's BASE (and EXTRAS) to its root.
  4. 4Insert the card and boot; first boot may take several minutes to install.
  5. 5Add ROMs/BIOS to the firmware's folders; emulators run on RetroArch cores.

The Brick Pro is a brand-new 2025 device, so community firmware support is still forming. The wider TrimUI Linux scene includes MinUI, NextUI, Knulli, CrossMix-OS and muOS, and projects often add new TrimUI hardware over time — but a build must explicitly support the Brick Pro's A133P platform and its dual-stick/4-inch layout before it is safe to flash. Until then, treat any 'Brick Pro' CFW claim with caution, keep your stock card, and verify support on the project's official page.

FAQ

Can I install MinUI/NextUI/Knulli on the Brick Pro now?
Only if the project explicitly lists the Brick Pro. As a new device its support is still emerging — don't assume Brick (TG3040) builds will work, since the Brick Pro uses different hardware.
How do I avoid bricking it?
Use a separate microSD for CFW, keep your stock card untouched, and only flash builds that name the Brick Pro on the developer's official source.
