Try doing it in increments.įrom vanilla try to upgrade to like version 1.x of the bios. I think you are trying to perform to large of an upgrade in your BIOS. I believe these missing strings are added by the missing application which is what is causing the BIOS Package not to run. I just can't seem to figure out which one I need. I know I am missing a crucial application that will allow the BIOS to update. I downloaded and installed, still getting the same error message. Upon trying to update the BIOS to the latest version I get the error "This computer is not supported." After doing much research I found that I needed the Value Added Package. I have a Toshiba Portege Z20t-C with a vanilla image. I believe these missing strings are what is causing the BIOS Package not to run. What sets these strings in the Toshiba image? I need to duplicate the process on a custom image.
I compared these entries to an identical model and all these items are set with the proper strings. PowerShell: Get-WmiObject -NameSpace "root\wmi" -Query "SELECT * FROM QuerySmbiosStrings"Ĭomputer\HKEY_LOCAL_MACHINE\SOFTWARE\TOSHIBA\swtos If you select the wrong BIOS you could brick your laptop.Īre you using the Toshiba image or a vanilla image (meaning no Toshiba stuff installed)? Using MDT, we install a custom image consisting of a vanilla copy of Windows 10 Pro, drivers and basic software our End Users will use. The BIOS could be also updated from a bootable USB or CD-ROM and in that case you need to disable Secure Boot and also change the Boot Mode from UEFI to CSM. What I have done in some laptops is disable Secure Boot before updating the BIOS
I have never had to install any Toshiba app before upgrading the BIOS. That would be a good reason if the BIOS in question would address that, but I don't see it on the logs on the BIOS for your model. What other Toshiba app would I need to install? The VAP does not seem to resolve the issue. This question is specific to the Toshiba app that needs to be installed before you can update the BIOS. Here is an Article in case you do not agree. Also, there are numerous reasons why you should update a BIOS. I believe I would not be asking the question if it was as simple the wrong file. The Toshiba Portege BIOS could be install from Windows, as administrator. Make sure you have the correct BIOS file for your device.
