WebUSB requires Chrome or Edge. Firefox and Safari are unsupported, and no iPhone or iPad browser will work. Caution SHU compatibility firmware limits: Do not use Flash SHU Compatible with F3/G3 VCU 1.6.3 or newer, or ZT3 VCU 1.5.9 or newer. GT3 is not supported by Flash SHU Compatible at any version (its own limit, VCU 1.7.2, is listed for reference only). SHU compat saves the original backup first, but using it on newer firmware may require restoring that backup. |
Supported models: ZT3 Pro, Max G3, F3 / F3 Pro

x3utils talks to the scooter VCU over ST-LINK / SWD. It makes full firmware backups, flashes firmware, runs SHU-compatible patch flashing, and checks or rescues a locked chip. The desktop GUI covers Windows, Linux and macOS. Web and Android provide direct ST-LINK subsets, while the CLI scripts offer the desktop workflow from a terminal.
Warning
This tool talks directly to the scooter VCU. A bad connection, wrong file, or interrupted flash can leave the controller unusable until recovered. Always make a full dump first and keep the backup somewhere safe.
Watch the quick video first.
This video shows the older CLI flow, not the current GUI. A GUI walkthrough is planned.
- Download the latest release for your platform.
- Make a full backup before you flash anything.
- Follow the guide for your platform: Windows, Linux, macOS.
The original CLI scripts still work and cover the same operations as the GUI, for anyone who prefers the terminal.
