Zte Mc801a Firmware Flash Link [extra Quality] -

I couldn’t find a verified, official “firmware flash link” for the ZTE MC801A that’s safe to share directly, as ZTE typically distributes firmware through mobile carriers or their own support portals (often login‑restricted). However, here’s a general review of the firmware update/flashing situation for this device:

• An official vendor download page for the device model and hardware revision (often an HTTP/FTP/HTTPS link).
• A carrier- or partner-provided image (sometimes delivered through an ISP portal or support ticket).
• Community-hosted builds or mirrored images (forums, GitHub releases, file hosts).
• Tools and documentation for flashing (SP Flash Tool variants for MediaTek, vendor CLI utilities, or device-specific recovery tools).

Conclusion

1. Carrier Swap: If you are on Three UK and experiencing issues, request a replacement unit. They often ship units with newer firmware.
2. Downgrade via Hidden Menu: Sometimes you can flash older official firmware via the web GUI. Navigate to http://192.168.0.1/index.html#/firmware_update while logged in as admin. Upload an older official .bin – no special tool required.
3. Sell & Replace: The ZTE MC801A is aging. Consider selling it "as-is for parts" and buying a newer 5G router like the ZTE MC888 or a Fibocom FM350 module in a USB enclosure.

• Requirement: You need the prog_emmc_firehose_SDX55.mbn (programmer file) and the raw partition images.
• Challenge: Finding the Firehose Programmer file for the MC801A is extremely difficult as it is a secure boot file usually not included in standard OTA zips.
• Status: Without the Firehose file, QFIL is useless for this device.
