Z27X firmware upgrade is not working

Z27X
Mac OS X 10.7 Lion

Followed instructions:

Internal management on

Wait a minute

USB drive insert

Upgrade found..

Error: not signed!

Redownload

Tried again

Same issue

 

Want to upgrade from 220 to 230

 

Any option to do this via network is not described in the manual...

What to do?

Z27X firmware upgrade is not working

Hi,

 

HP doesn’t have an official presence on this forum other than for administration and moderation. The assistance that you receive is mainly from volunteers. 

 

There is not a lot of MAC expertise on this forum.

 

Carefully read through this procedure if you haven't already done so.

Thank you Big_Dave,

I already toke the tour through the procedure you indicate with the 'error' mentioned before as a result.

Tried many more times redownloading and even re-formatting the USB flashdrive et cetera

Big_Dave I noticed that the download has a volume of 82,7 MB

But all downloads are cut of at around 44 MB

The file might be corrupted?

All leads to the same file on a HP ftp server.

Can you send me a checked file?
