Tenda D305 Firmware Update -
Downgrading is possible but not recommended. If necessary:
This guide is for informational purposes. Always refer to the official documentation provided by Tenda for your specific hardware version. Tech assistants are not responsible for any damage caused during the firmware update process.
Now, do not restore your old backup file. That defeats the purpose of the update (you might restore the bug).
Tenda has produced multiple revisions of the D305. Using the wrong firmware file will corrupt the device. Look at the sticker on the bottom of the router for: Tenda D305 Firmware Update
Do not update over Wi-Fi. A single dropped packet over wireless can corrupt the flash memory.
Otherwise, I strongly recommend only using official firmware updates from Tenda to avoid permanent damage.

Do not update your Tenda D305 over Wi-Fi. Always use a wired Ethernet cable connected to the router. If the Wi-Fi disconnects mid-update, the firmware can become corrupted, "bricking" the device permanently.
