bizhub C450 firmware

I've been asked to look at a bizhub C450 that an upgrade at install went pear shaped.
I have tried loading v50 on but it just stalls at the printer file upload, start button remains flashing red but nothing comes up on the screen to say its failed. You power on the machine and you get a C-C153 error, relating to rom failure.
We have recovery firmware but that does the same, stalls at printer upgrade. I have no documentation on the recovery firmware but guess as it is a tar file that we still use the firmware writing tool to a CF card. Does anyone have a version of this or they know of the recovery version?
Any help is appreciated, don't particularly want to replace a main board if it can be helped.

Not sure what you mean by recovery firmware. It may be something I have not needed to use yet. The utility to write the firmware to the flashcard is still the Cygwin utilities. Cygwin is actually a set of Linux/Unix routines that runs under windows, and some of these commands are used to write the flashcard. You can get the current version of cygwin here: http://www.cygwin.com/
One of our forum members in Australia sent me a windows executable to write the cf cards a couple of years back, but it turned out that the type of source files it wanted were different from what is made available in the US, so it wouldn't work.

One of our guys (Australia) wrote an application with a nice gui but of late it seems to be a bit hit or miss. Loads of unable to read flash card errors. I'll have a look at that site and might try it that way. Could it be related to the type of CF cards being used? We have tried various brands but all seem to error at some point on various pc's and laptops.

One important thing with cygwin (or at least the batch file that writes the cf cards) is that it does not seem to like it being in other directory but C:\cygwin.
When you write the flashcard, watch the dos window while it is writing the card. It should verify the files after writing them. Make sure it did not error out on those. A while back, I had a usb card reader that would not behave with writing the firmware, and gave errors. I suspect this same card reader of also being responsible for toasting a Bizhub 600. I gave the reader away and cautioned the guy to only use it for casual file transfers and to NOT use it for writing firmware.
I have not had any problems with the flashcards I have used. I've used a Sandisk card that I bought locally and several brands of cards that have been supplied as a Konica-Minolta part number.

Our company just released a tech bulletin yesterday on updating
our imagistics cm-4520 which is the minolta bizhub c450.
I don't know if the version numbers are the same as minolta but
the one thing that caught my eye was when upgrading from
phase 1.x to phase 2.01 the machine must be upgraded to
phase 1.8 before upgrading to phase 2.01.
once you update the firmware, downgrading the firmware to phase 1.x
is not possible.
I don't know if this is what you have going on or not but I thought i'd
post it.
There was also a section on restoring the NVRAM data but your
error code doesn't match but I'll post it anyway.
press [stop]>[0]>[7]>[1]>[3]>[9]. An [*] will be shown on the
control panel. Bypressing the [*] the data restore can be initialized.
hope this helps,
good luck.

phase 1.8 before upgrading to phase 2.01.Yes, this is important. Since the version numbers are a confusing hexadecimal number, I keep two flashcards and always update to the latest prior version before putting phaseII into the machine. Takes a few extra minutes, but this way I know it has been upgraded properly.

it could possibly be dqydj as the tech concerned wasn't sure which version he had downloaded.
I have recieved a convaluted fix that I am seeking clarification on, but will keep you posted on the result. will try resetting the NVRAM if it allows me access to that code.

problem fixed. an older version had been attempted to be loaded. no fault on the techs side, he was updating as per the latest version available to us. unfortunately the new m/c came out with a more current version (for those who are not sure, determining what version is on the m/c can be tricky). the fix being to run a recovery firmware on a good m/c, then take out PWB-MC and put it in the faulty m/c and run the recovery firmware again then you can load the latest firmware. and yes you have to order another PWB-MC for the good m/c. easiest fix, check the firmware version first before upgrading, if you are not sure, ask someone who is )

Unlike the machines with Konica style firmware, that have clear version levels, these are a little trickier to be sure of.
One easy check to see if the machine already has phaseII firmware is to look in the scanning function under scan options. If there is a button at the bottom of the screen to enable naming the file at the machine, then you have phaseII already loaded. When I upgrade one of this type of machine, I always put a label on the plate that covers the CF card slot with the version level I installed. That way the next guy to come along knows it is at least at this level. I think at least one of my coworkers is also doing this, not sure about the rest, but i haven't seen too many labels.
What is the recovery firmware you mentioned? I haven't seen anything like that.

Thats a good idea Yo Spiff putting a sticker to let the next guys know, may try and suggest that here.
As for the recovery firmware, wasn't able to be explained as to what it is but I gather its like a basic bootable version because after you load it, the copier comes to ready, so its firmware of some description. I didn't check to see what ROM version was showing, honestly needed to put in the updated firmware and get it out the door to the customer ASAP.
Its labelled as a special version of phase 1.8, wether its related to that version, not sure.
