wax510d firmware checksum error on USG40W running V4.62(AALB.0)

After upgrading the USG40W from V4.62(AALB.0) to V4.62(AALB.0) the option to check for new firmware via the web gui no longer works - the button is greyed out. To get around this, drop to a command line and run the following command : 
configure terminal
capwap firmware-update check
This definitely starts the firmware update process (doesn't solve the greyed out button) but the logs begin looping through the following error : 
show logging entries category ap-firmware begin 1 end 10

     alert               ap-firmware                                                            
     AP firmware download failed. Reason: wax510 Firmware checksum is error.

     alert               ap-firmware                                                            
     AP firmware download failed. Reason: wax510 Firmware checksum is error.

There appears to be no option to stop the firmware update check and so this just keeps looping indefinitely. 

router(config)# show capwap fw-updating info 
APs in fw updating : 0
concurrent fw updating method : capwap
FW updating mode : manual
Runtime firmware : V6.00(.6)
Available firmware : V6.10(.9)
ZAP version : ZAP9
Last Check : Success, 2021-02-01 15:55:11

According to the web (is there a way to find this in the cli?) the Runtime firmware for the WAX510D is Local / V6.00(ABTF.9)

That progress bar just loops through percentages and repeats. Been going on for 20 hours now.

    I also had this problem on USG60W V4.62 and in the end I updated the AP firmware manually same model AP too forgot to report it but I have been troubleshooting a problem with WDS.

    likely a corrupt file or checksum wrong

    Hi @danyedinak

    Thanks for the detail information and steps, we used the same fw and followed the steps but can’t reproduce. Could you provide diaginfo file of USG and AP for us to check? You can collect and download at: Maintenance > Diagnostics.

    We’re sorry for causing your inconvenience of impacting service.

    If you need the service back right away, the workaround can be reboot USG to resolve hangs on the progress.

    Note that diaginfo should be collected before reboot.

    Same problem "AP firmware download failed. Reason: wax510 Firmware checksum is error." occur on our Zywall 110 fw V4.62(AAAA.0). The download loops infinitely.  
    The WAX510 remains off-line, 
    Tried moving the AP to the group Unclassified to no avail. - Even after rebooting the Zywall, the loop continues.

    open web console on the Zywalll with this:
    debug system _disk-cleanup

    Hi @InterLAN


    Can you provide us the firmware version information of WAX510D?

    We’ll test the steps as yours and figure out what's are going on with the problem then update you.
