Flash Usage and Update

FANAT · March 2021

Good day.

I cannot update the firmware. every time an error is displayed:

Update Standby Partition (Total: 0Mb)
Error: Firmware update fail - checksum error: 400

I think this is due to the fact that Flash Usage is used by 96%.

Am I right?
How do I update the firmware?

Boot to each firmware and remove any packet capture files and diagnostics files.

Hi @FANAT

Please answer to following question in order for us to understand the problem;

1- What is current firmware version of Zywall 110?

2- Did you try after deleting unnecessary Configuration files(Maintenance > File Manager > Configuration File) and Diagnostic files(Maintenance > Diagnostics > Files) ?

3- Can you upgrade firmware by manually (Maintenance > File Manager > Firmware Management > Local Firmware ?)

In addition, you can try following command for cleaning flash usage and try again firmware upgrade;

GUI > Web Console

Router# debug system _disk-cleanup

The instruction you sent did not help.

I am using firmware version

V4.39 (AAAA.0).

I downloaded the latest firmware 4.62 (AAAA.0) from https://portal.myzyxel.com/my/firmwares and updated it manually.

The update was successful.

Thank you for your quick response to my question.
