## Symptoms

- Checking for a firmware upgrade fails on SMB appliances running R77.20.81 (990172525). The same issue can also occur on appliances connected to the Security Management Portal (SMP).

## Solution

Manually upgrade from the WebUI to the latest firmware version [R77.20.81 B2541](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk137212) (or above).

If a manual upgrade from the WebUI is not possible, run the following commands in expert mode:

* ***\[Expert@GW\]# /opt/fw1/bin/fw check_available_firmware***

(Prints a debug; make sure the *cat /fwtmp/firmware_check_result* is "0" or "5" if the appliance is connected to the Security Management Portal.)

* ***\[Expert@GW\]# /opt/fw1/bin/fw download_firmware***

(Downloads the firmware to*/storage/firmware/* . Should print: �Firmware was successfully downloaded.�)

* ***\[Expert@GW\]# /pfrm2.0/bin/cloud_upgrade.sh***

(Performs the actual upgrade and reboots automatically.)
