| Problem | Likely Cause | Solution | |---------|--------------|----------| | PC does not detect charger | Bad USB cable or missing driver | Use a known good data cable. Reinstall STM32 drivers. | | Updater tool crashes at 50% | Interrupted power or wrong firmware file | Re-download the file. Ensure AC power is stable. Restart from Step 4. | | Charger screen goes black after update | Incomplete flash | Perform a “recovery flash.” Put charger back in DFU mode and re-upload. | | Error: “Target not found” | Wrong COM port or charger not in DFU | Check Device Manager. Repeat DFU mode procedure. | | New features not appearing | Updated wrong variant (e.g., T240 non-Duo) | Double-check model number. Download correct firmware. |
Critical updates can improve thermal protection during high-current charging and refine internal algorithms to prevent overheating.
However, like any smart electronic device, the HTRC T240 Duo is only as good as its software. Over time, manufacturers release firmware updates to fix bugs, improve balancing algorithms, add new battery chemistries, or enhance safety features. Performing an is not just a maintenance task; it is essential for unlocking the charger’s full potential and ensuring the longevity of your expensive battery packs.
do not use random files from forums. Instead, email HTRC at: support@htrc-europe.com or message their AliExpress store with your current firmware version shown on the charger’s startup screen.
