Invalid Cache for BIOS Updates

Question

We have been experiencing issues pushing BIOS updates to our Wyse 5070 Thin Clients.  I cannot find any common factors between the systems that will update and those that will not.  We see this message in the even log: wms: ignore remote package:      (invalid cache) bios: 1.21.0   Firmware and application updates are not affected.  We have tried different versions of the BIOS and reuploaded the failing BIOS packages.  As mentioned before some of the Thin Clients will update and others will not.  Also not seeing any issue with Optiplex 3000 Thin Client BIOS Updates.   If anyone has some insight into what's happening here it would be appreciated.

'Invalid Cache for BIOS Updates' usually means that there is an issue with the cache memory on the computer's motherboard that is used to store BIOS updates. This can happen when the cache memory is corrupted, or when there is an issue with the BIOS update itself.

@John harper do you know an easy solution for this which could be applied remotely ?

Is there a way to remotely reset the cache, so that BIOS install can take place next reboot ?

Or is the only way to visit the device, factory reset it and start from scratch ?

Thanks,

Hansjoerg

Hi, I have found a solution. We are upgrading to version 9.4.1141 Downgrade to version 9.1.3129 and then upgrade again to 9.4.1141 After that you can upgrade the BIOS to 1.21.0 Hope this helps Yryk
