We have had to remove the Micromax Q450 firmware from our server when reducing expenses.

If you need the Micromax Q450 firmware, you can check one of our competitors. Usually, there are at least a few reliable sources of the firmware files, though we do not know any of our competitors so we cannot recommend them.

You may also find a free Micromax firmware update tool capable of downloading the Micromax firmware directly from Micromax’s own servers.

Lastly, you could try getting in touch with Micromax and asking if they would be willing to share the firmware file, though often manufacturers of smartphones much prefer you to send in your device for repairs before they will hand over such files.
