Failure to Repair Brocken BIOS on Latitude 9410 with broken BIOS

HELP DELL: The laptop case indicates a Latitude 9410. With a TAG of and an Express Code of <To protect your privacy, all private information was removed from this public post. DELL-Admin>

But if you put the TAG on DELL support Web site it gives it as Latitude 5510 with a different Express number. I can't get into the Broken BIOS to check the details from the BIOS and it doesn't want to load the BIOS repair software probably because it is for a different model, DESPITE using the TAG on the cases! I can't speak to DELL the CHAT BOT can't deal with this. This is not a home user. But an IT volunteer at a local charity trying to repair this device.

Since the error specifically states "BIOS blocked due to unsupported downgrade" then are we using the latest BIOS version 1.41.0? This version in particular does restrict downgrades. It seems like you've already followed the other steps in our BIOS recovery article as well. If the BIOS continues to remain corrupted despite using the latest version, then I'd recommend contacting support as the only major alternative would be to replace the motherboard. 

Maybe DELL manufacturing explain why the CASE says is a DELL latitude 9410 with an Express code on the label ### (I know it out of warranty but when first delivered that was the code associated with the laptop).  BUT when you enter ### it says it is a Latitude 5410 and says the express code was ###.  And it downloads a BIOS recovery for a 5410.  But if the machine is as 9410 then that recovery software will be wrong - hence maybe the unsupported error.  Bit OTT to change the motherboard when the PC appears to be working but no BIOS!  We should be able to re-flash the corrupted BIOS but it doesn't help when one is not sure one has identified the machine correctly.  Can DELL look in their manufacturer database and let us know what this machine is before we through it away.  Would be greatful for some DELL techie help.  Thanks

@grahamm7​ If this unit was received as a donation to the charity, then we could have some mixed parts in use with the tag. You would have to remove the bottom cover to gather PPID information and provide it to Dell Support to help identify the unit. If a posted service tag is listed as a 5410, then we would want to use the latest BIOS version for that model and not a 9410. Not too sure how those 2 models would have been mixed up as well since they are entirely different platforms. 

In any case, I'd recommend trying the latest BIOS from a 5410 and a 9410. If the BIOS is recovered with one of these versions, then that'll let you know which model it truly is. At that point though, the BIOS should likely be recovered and then it will be useable again. However, if you still can't get either version to work with the recovery, then right, the motherboard would have to be replaced since its corrupted. At which point, it'd be your call to dispose of the unit or look into an out of warranty repair. 

Are not most 9410s 2-in-1s ?
