We have recently discover some of our clients with serial numbers need patching (in preparation for Firmware 7.1.1) though our beta test processes and client system reviews. This is the process we have developed for applying the fix when systems are managed by InControl2.
Note #1: You can not use the custom firmware options from within the InControl2 Firmware management to push this fix to the units as they will get stuck attempting to do the firmware update and need a manually reboot, this reboot (which can be pushed from InControl2) will restore the unit to the working firmware before the failed attempt at the patch was done
Note #2: This downgrade process and restoration of current firmware works with FW 7.1.0 from our testing even if both firmware slots are running Firmware 7.x
RAM Timing Process via InContrl2
Download the configuration current configuration before before beginning the process.
Step #1: Set up at either a device, group or organisation level the version of firmware you want running on the router (for this example we are using FW 7.1.0).
Step #2: Following the link from @Alan, download the firmware to a computer where you can access the Web Admin page from, for this process we are basing on that your can access the device using InControl2’s Remote Web Admin.
Step #3: Navigate to the menus of System / Firmware
Upload the firmware file download in Step #2 with the Manual Firmware Upgrade process.
Step #4: Let the system reboot, this will happen twice, once to apply the patch and a second time to apply the firmware nominated from Step #1. This process could take between 10 to 15 minutes to complete, we have seen it take less than 5 minutes depending on connection and system environments.
Check the settings and reload the previously downloaded configuration if there are any discrepancies.
Caution: This process is not without risk, we can not guarantee that the process of going backwards with a firmware version will carry all of the system systems required to get your device restore/online remotely to InControl2 though this process has work for all of our system tested to date, therefor proceed with caution and consider having backups of the configurations and a paperclip handy at each site.
Happy to Help,
