# Firmware Flash

Full flashing and upgrade instructions now live in the consolidated setup guide:

- [[teltonika_flash_guide]]
- [Installing the UB-EDGE sysupgrade image](teltonika_flash_guide.md#install-the-ub-edge-image)
- [Post-flash controller checklist](teltonika_flash_guide.md#post-flash-controller-checklist)

Use this page to capture device-specific nuances that do *not* belong in the main guide (e.g., lab automation scripts or emergency recovery tricks).



## Additional Hardware (Placeholder)
