How to Update Your Scanner
📡 Over-the-Air (OTA)
Recommended
- Connect your scanner to Wi-Fi via the companion app
- The scanner checks for updates automatically
- Tap "Update Now" when prompted
- Wait for the LED to stop blinking (30-60 seconds)
- Scanner reboots automatically with new firmware
🔌 USB Manual Update
Via CEH PC Tool
- Download the .bin file from this page
- Connect scanner to your computer via USB-C
- Open the CEH PC Tool (see below)
- Go to Tools → Firmware → Manual Update
- Select the .bin file and click "Flash"
- Verify SHA-256 hash matches (shown above)
💾 microSD Card Update
No computer needed
- Download the .bin file to your computer
- Copy it to the root of a FAT32-formatted microSD card
- Rename to
firmware.bin - Insert the microSD into the scanner
- Power on the scanner (OBD-II or USB-C)
- Navigate to Settings → Firmware → Update from SD
- Scanner validates, flashes, and reboots automatically
This mirrors the update flow used by many professional OBD-II tools. Useful when the scanner has no Wi-Fi access, like at a racetrack or in a garage without internet.
💻 CEH PC Tool
Desktop companion application for advanced scanner management. Connect via USB-C for firmware updates, data log review, PID configuration, and gauge layout design.
CEH PC Tool
Full-featured desktop companion for the CEH Scanner. Manage firmware, review data logs, configure PID libraries, design gauge layouts, and export diagnostic reports.
| Firmware Manager | Flash updates, verify hashes, rollback to previous versions |
| Data Log Viewer | Import SD card logs, overlay multi-channel graphs, export CSV/PDF |
| PID Editor | Browse, search, and add custom PID definitions for your vehicle |
| Gauge Designer | Create gauge dashboard layouts, assign PIDs, set alert thresholds |
| Session Export | Generate shareable diagnostic reports (PDF) with annotated data |
A single install that handles everything the mobile app can't: large-screen data log visualization, bulk PID management, and direct USB firmware flashing.
