Hi Parvis1

Thank you for your question. The firmware package M277_MFP_Series_FW_Update-20150716.exe was an early release for the HP Color LaserJet Pro MFP M277 series. HP has since removed this file from its support site and it is no longer available through official channels.

HP policy is to replace older firmware with the latest version only. This ensures that all devices run the most up-to-date code with security patches and stability fixes. Older releases such as 20150716 are retired and cannot be re-downloaded from HP Support.

If you are experiencing a “Supply Memory Error” or cartridge recognition issue after a firmware update, we recommend:

1. Print a Printer Status Report (on the control panel, go to Setup → Reports → Printer Status Report) and check the Firmware Datecode.

2. Update to the current firmware available directly from HP here:
   👉 HP Color LaserJet Pro M277 Series – Software and Drivers

3. If the error continues, try reseating or replacing the cartridge. In many cases the issue is hardware-related rather than firmware.

At this time, HP does not provide any way to revert to earlier firmware versions. For reliability and security reasons, only the latest firmware is supported.
