Need .plt file for firmware upgrade - EMERGENCY

HP Recommended
HP DesignJet T1100 Printer series

I am unable to access the EWS due to 79:04 error, I have tried all troubleshooting steps and nothing is working so I want to update the firware but since I can only access the plotter through FTP I need the .plt file but it doesn't seem to be anywhere. I need that as soon as possible please

Firmware is not PLT file for this model.

Download file from link

Unpack it with 7zip

Upload larger file with FileZilla (since it needs passive ftp which is not so food supported with Windows Explorer) to printer's ftp.

& tell us what you acomplished.
