Bad G4 Firmware Update - How to get a "healthy" Firmware?

After a crash while a firmware update installing the Sonnet Encore 1,8 GHz Upgrade some programs crash during their startup for some unknown reason (espacially Adobe Software: Photoshop a.s.o.). I installed OSX several times, but the problem persisted. The upgrade processor isn't installed anymore. Before this crashed Firmware update everything was working. The guys from Sonnet told me that my firmware was corrupt and tried to correct it, but they didn't give me a new one. Is there a place where I can download the firmware for my G4/400 Gigabit Ethernet and a way to install it?

G5/2,5 + G4/400 Mac OS X (10.4.6)

To install firmware updates you need to be running in OS9x (does not work on these machines in OSX), and you can find firmware update 4.2.8f on the Apple website, just look up G4 firmware updates on the support part of the site (not on the discussion forums search though).

Thanx, but I know that. My Firmware has already been updated to this version. The Updater recognizes that and so I can't install it a second time.
I installed the 4.2.8f before the Sonnet-Firmware-Crash.
I'm looking for another way to get my firmware like new...

There is no way to get the original firmware back, Apples site only has the newest version for download. Your idea of reinstalling the OS will not help, the firmware is on the logicboard, not your hard drive. You could try a google search for older Apple firmware, but I doubt you'll find any for your machine, since the original firmware was never downloadable.

I know that.

That's why I posted this message.

There is a utility called PM G4 ROM UTILITY (the guys from SONNET sent it to me) what can read out & write a G4 firmware.
But I need the firmware in the file format this tool reads it out (not as a program like Apple has it in their downloads).
