Beetel 450TC1 Firmware Updates before TM4-0Q-025…

I have Beetel 450TC1 Modem using with a BSNL connection. This was working perfectly till yesterday… until I thought to update it with the latest firmware. I searched over the Google and found the latest firmware for Beetel 450TC1 Firmware at Airtel site at the link here

Now, what happened after the update, the section to provide wi-fi password was disabled. I no way I can enter the password, even the wi-fi of the modem was disabled. Even after several on and off the modem the problem remains there. So, finally I only left with the solution to downgrade the firmware with older version… and I googled for the same. But there I found only few links describing about Beetel 450TC1 model.. though there are many talking about 450TC2 model.

So, if you are also among the same side, bricked your 450TC1 modem with the latest firmware and looking for the older versions below are the download links. In the below links I have added three Beetel 450TC1 Firmware updates TM4-0Q-008, TM4-0Q-011 and TM4-0Q-020. For me TM4-0Q-008 firmware have done the job…

Here are the download links:

TM4-0Q-008TM4-0Q-011 and TM4-0Q-020

Though, I have added the firmware, but it is all up to you to use them… for any misconfiguration or bricking I should not be held responsible.


  1. This post was really very helpful. After upgrading with latest firmware TM4-0Q-025 from TM4-0Q-020, I faced Wi-Fi configuration issues where the the SSID colum and Authentication Type dropdown was restricted and could not be edited.

    Hence after lot of searching and troubleshooting, had to downgrade to older version of TM4-0Q-020 provided by you here for download.

    Other settings where internet was working was fine and on completion of downgrade to TM4-0Q-020, the modem took the same settings as earlier and started working fine and I was able to again edit the Wi-Fi cofiguration area and completed the settings. All is well and is working fine on my BSNL UP East broadband connection in Gorakhpur area.

    Thank you whoever has created this post and gave the details plus the older version.

    Cheers and best wishes.
