I face the same issue.
Unable to update from V3.50.01.08 to V3.50.02.02. The update wizard works fine but after reboot, the firmware version is still old.
Tammy, thank for your answer.
Today I tried to find any instructions about wired updating, but found nothing.
Also I can't find any updating window in Wired Xerox Centre.
Can you point our any instuction for wired update process? Xerox Phaser 3020. Thank you.
This forum is for Xerox printers, I suggest trying a forum for your TP Link router.
I searched our online knowledge base and could only find instructions for wired connection, nothing mentioned for a wifi connections. I would suggest calling into the support department for assistance @ 1-800-835-6100
I try to shooting bug when I can't update main firmware of my Xerox 3020 B.
Now it have V3.50.01.10 JUN-02-2015
I try to install V3.50.02.01 JUN-31-2018
I followed all from instuction inside firmware zip-file, Wizard says that all is ok and I press Next.
Then I wait for a minute, printer rebooting, connecting but firmware still old.
I haven't any error messages while upgrading and after it.
