Your CRBN DRV, your look.
Boot animation, your name on the main screen, your colour and a fresh icon set. Set it up in your browser and flash it over USB in about two minutes. No apps, no terminal.
Reads the firmware already on your loader and changes only what you pick. Restore to factory any time.
Three steps, two minutes
- 1
Plug it in
Connect the display's USB-C port to your computer and open this page in Chrome or Edge.
- 2
Make it yours
Upload an image or GIF for the boot screen, type your name, pick a colour. You see exactly what the display will show.
- 3
Flash
Click Write. The tool backs up, verifies and writes your loader. Power-cycle it and enjoy.
What you can change
Boot screen
Any image or GIF, 240×135 in 16 colours, shown for 3 seconds at power-on. Add several and switch between them from the loader's own menu.
Your name on the main screen
Logo and name fixed on the bottom bar, next to the timer. Your loader, labelled.
Your colour
Replace the factory orange with any colour. It stays selectable in the COLOR menu, with the originals still there.
Modern icon pack
Rounded, cleaner icons for play, pause, battery, force and the rest. Optional, one switch.
Built to be safe
Your firmware, not ours
The tool reads the firmware from your own loader and patches that copy in your browser. Nothing is downloaded from us, nothing is uploaded anywhere.
Exact version check
It only touches the one display firmware it was built and tested for. Anything else is refused before a single byte is written.
Restore from any computer
A compact undo record travels inside the custom firmware, so Restore factory rebuilds and verifies the original even without your backup file.
Not a brick risk
The display's chip can always be re-flashed over the same USB cable. If a write is interrupted, plug in again and retry or restore.
What you need
- A CRBN DRV loader with display firmware v2.0.1 (build 0816c34, Dec 30, 2025). The tool checks this for you.
- Chrome or Edge on a Windows, Mac or Linux computer. Phones and other browsers can't talk to USB devices.
- A USB-C data cable from your computer to the display's USB-C port.
Questions
Is this an official CRBN tool?
No. DRV Customizer is an independent project by DataPrime and is not affiliated with or endorsed by CRBN Paintball. CRBN and DRV are trademarks of their owner.
Can it brick my loader?
The display runs on an ESP32 chip that can always be re-flashed over USB, so a failed or interrupted write is recoverable: reconnect and write again, or use Restore. The main loader board is never touched.
Will I lose my settings?
No. Force, timer, colour choice and the rest live in a separate settings area that the tool never writes.
What about firmware updates from CRBN?
The custom firmware replaces the display firmware in place. If CRBN ships a new display version, restore factory first, update, and check back: the tool refuses versions it doesn't know.
Why Chrome or Edge only?
Talking to a USB serial device from a web page needs Web Serial, which only Chromium browsers support. Nothing is installed; the page simply asks permission to use the port.
Does anything leave my computer?
No. Reading, patching and writing happen in your browser. There is no account and no upload.
How many boot animations fit?
Each animation keeps up to 24 frames. A meter shows how much flash your selection uses; if it outgrows the factory partition the tool enlarges it automatically.
How do I switch boot screens on the loader?
Open the menu and scroll to the new last entry (STARTUP). Up and down change it; the choice is saved.
How do I go back to stock?
Connect and press Restore factory. The tool rebuilds the original firmware from the undo record, verifies it and writes it. Your downloaded backup works too.
