About temporary password for Firmware downgrade on HP Ultrium 448

[mark david_2]

After upgrade firmware from S22 to S65,
Now I'm getting some errors on the LTT's assessment test

I think temporary password is needed to downgrade firmware
anyone can inform me about temporary password?

thank you for reading

I doubt if a downgrade helps.

What errors???


However, HP support can help you with this password.

Agreed. A downgrade will not help here.

Best bet is to post the ResultLog.ltt, EventLog.ltt and a support ticket so we can take a look.

Need a bit more detail than 'some errors'!

Is it problem to upgrade/downgrade firmware freely for enduser?
I have not seen any product to restrict firmware operation.

When new firmware is brought out it typically fixes a number of (usually boundary case) issues and is regression tested for several weeks within HP and also with our partner application vendors.

At that point, all the support processes are updated to say that the latest firmware is now the supported one so if you ever need to call HP support the first thing they will do is to check your firmware version and ask you to update it if necessary.

There's usually no value in going backwards with firmware (I can't think of a case that has helped with our drivess) and the symptoms that you have don't look to be firmware related.

All of this is why we make it deliberately awkward to go backwards!

Having said all that, if you're determined to try it we can get you a temporary password. Please email the LTT support team at LTT.team@hp.com and they'll reply with the password. Please don't post it back out to the forum!

I'll let them know there's an email coming.

Let us know how you get on. Thanks.
