This is a download link to a vertion you can do a complete SD card reformat and setup, / firmware reload to base with? I'll see if I can find the specific level you mentioned and send you a link in a separate reply
This is the SD software. Try a new SD card
To prepare the USB thumb drive for an AltBoot restore, create an ALTBOOT folder, in the root directory. The folder name must be all uppercase. Next, using Notepad or similar utility, create a zero-length file in the ALTBOOT folder called FORCED_UPGRADE with no extension. Again, this file must reside in the ALTBOOT folder and be named exactly as shown. Finally, copy the latest firmware file (*.dlm) to the ALTBOOT folder.
Turn the printer Off.
Insert the prepared USB thumb drive in the USB Port on the printer’s rear panel.
Turn the printer On. The printer reads the USB port and begins the restore process.
The splash screen displays the ENERGY STAR logo while the printer reads the thumb drive.
The restore process begins with Check Firmware Version being displayed.
Next, the Software Upgrade screen is displayed. Depending on the system configuration (Trays, Finisher) the process can require approximately 20 minutes. The Software Upgrade screen changes to reflect the current subsystem being restored.
After the firmware update process is complete, the AltBoot Complete screen is displayed instructing you to remove the USB thumb drive.
Remove the USB thumb drive from the printer’s USB Port.
Wait for the printer to reboot and return to Ready To Print.
Re: Phaser 7800 rebooting
Okay the Phaser 7800 is a little bit different in what you have to do to fix your problem.
First, after you install the new HDD you must do a ALTBOOT with the FORCED_UPGRADE line in that folder as well the firmware .DLM file.
I would also replace the SD card as well.
Okay here is the trick you must first do the ALTBOOT with a very early version of the firmware 081.150.103.05600 or earlier.
After it completes immediately perform a image overwrite. This will correctly format the new drive with the correct partitions. (The newer firmware’s do not correctly create all the partitions necessary.)
Second you must now perform a upgrade to firmware version 081.150.104.16200 from CWIS accessed from the browser this firmware is necessary to allow ANY of the later firmware's to be installed. (This firmware is called the BRIDGE SOFTWARE)
Third perform the final firmware upgrade to version 081.150.109.12600 or later.
If you do not follow this procedure you will be back with either a reboot problem or a frozen display on boot up.
Good morning, all right, I have a xerox 7800 printer, the sd card gave an error, I need the iso to rewrite in another one, I saw your comment in a forum, could you send me please in my email? thanks. hdo2337.rr @ gmail com
