Firmware upgrade bricked Phaser 7500DN - How to recover?

[JoePerches]

Hello.  I recently got a Phaser 7500DN in good condition.

After downloading and sending the 5.26 firmware to the device, it now no longer lights the control panel at power-up.

I presume the firmware upgrade bricked the machine.

Is there a recovery mechanism?

Any help appreciated.

Hello Joe,

Sorry you are having trouble with your device. I have searched our online Knowledgebase and found some steps that may help.

How/where did you download this firmware? I'm unable to.

[JoePerches]

I'm not sure you want to download firmware that bricked the device, but it was the 5.26.1 version.

Thanks Joe. The interesting thing is that the second link does not work for me. Has it been taken offline?

[zavio]

where you able to un-brick your printer?

The link below works for me.

https://www.support.xerox.com/support/_all-products/file-download/enus.html?contentId=135576

It currrently shows:

• Filename Phaser7500_mer31.1__PS5.31.3_flash.zip
• Version OS 9.73/PS 5.31.3/43.21.01.25.2018
• Date Feb 1, 2018
• Size 34.4 MB

And no joy so far.  I bought a new main board from ebay.  I'm hoping that works when it arrives.

funny.. the link doesn't work on my end... perhaps it's because I'm from canada.

[JoePerches]

Or maybe because the server is offline or the file is protected now as it bricked my hardware.
It did work for me on November 7th and it does not now work for me either.

replacing the main board with the ethernet port made the device work again.

I'm not doing another firmware upgrade...
