The Brick Pro is a newer 2025 TrimUI handheld (Allwinner A133P, 3.95-inch screen, dual analog sticks) running TrimUI's Linux-based OS, and at the time of writing it is still launching, so dedicated firmware documentation is thin. TrimUI's other Linux handhelds flash a single .awimg file from a FAT32 microSD card using the VOL− + POWER combo, and the Brick Pro is expected to follow the same pattern — but confirm the exact file name, repository and combo on TrimUI's official channels before flashing.

FAQ

Where is the Brick Pro firmware?
Look for an official Brick Pro entry on trimui.com or TrimUI's GitHub. Because this device is new, a dedicated repository may not be published yet — verify before downloading anything.
Is the update combo confirmed?
Not officially documented here. TrimUI's Linux handhelds typically use VOL− + POWER with a FAT32 card, but confirm the Brick Pro's exact procedure in its official guide.
