HP477 frozen screen after auto update

[Roary45]

HP477 did an auto update overnight, now the LCD screen is frozen, the printer can't be accessed via network, wireless, or USB, power button does not work, can only power down the printer by unplugging the mains cable. Does anyone know how to factory reset when you can't use the screen or a PC to conect.

I was able to factory reset during the few moments before LCD freezes (after unplugging/replugging). LCD is still frozen. I don't know what to try next.

What the heck. It was frozen and I opened the cartridge door to get the Serial number. Had it open for a while, then all of a sudden it said "Close Cartridge Door" and started working again! ......and now its not. omg.

I am having the same problem.  HP tells me that they are working on a fix and will let me know when it is available.  I am going on day 2 at the office with no printer, copier, scanner.  Hoping they have a fix before Monday morning gets here.

Based on what I am seeing on these boards here are some steps to try:

1. Turn off wireless and disconnect any ethernet cable from the printer. In some cases you may need to temporarily disable your wireless router to test this.

2. Power the unit on. Many posts here state that they were able to get the printer to ready with networking disconnected. If the printer comes to ready then you will likely be able to resolve this.

3. download the firmware update utility for your printer from support.hp.com. Version needs to be 2313A or older

4. Using a program called 7-Zip, extract the .ful2 file from the file you downloaded and copy to a USB Pen drive.

5. Insert that pen drive into the USB slot by the control panel. A USB icon should appear on the control panel. Touch it and there should be an option "upgrade detected". It can take up to ten minutes for the printer to realize the upgrade is there so be patient. Once you see the icon,  touch it and the firmware downgrade will be applied. 

6. When unit starts back up, turn off automatic updates so the problem firmware is not reapplied.

I am having the same issue and  was able to factory reset. The factory reset just delayed the screen freeze. It did not resolve the issue.

Regarding the question above,  'Is this being addressed? it has been 3-4 days now and still facing the same problem with no update from HP' :  Let's hope HP are working on it, as they have a planet of customers with bricked printers. If they eventually release a patch, it seems like the are methods above to boot from the USB drive, or to update the firmware from there.  Really bad that Hp have not proactively contacted registered customers to say they are aware of the issue.

I and another user have both posted different but working fixes for this issue. HP for their part have withdrawn this firmware from all public facing sources while they work to determine and fix the issue. Even when they come up with a fix you will likely have to go through the same steps I have already documented. So you can wait for HP (firmware changes can take weeks) or follow documented steps and get back to printing now.
