I used the tool Win_FWTool_v220.127.116.11.zip and upgraded my phaser 6510 with this firmware 64.21.81_PH6510.zip.
The tool showed 100% and I closed it after the message, the printer showed 100% of the download finished, then it showed please wait and restarted.
Now I restarted it a serveral times it only shows "Please Wait ..." for hours ...
I think maybe the firmware update failed and it is not possible to boot.
Is there a way I can factory reset the printer to its default firmware? When I am trying to push buttons a LED starts to blink in an violett/ red light and the "Please wait..." Message still keeps.
How long does the installation took place after the update? I mean it were 250 mb ...
Did you have any luck getting this fixed in the end?
Ive got the same issue, and after 4 calls to support I have failed to reach anybody, it seems I wait on hold for about 20-30minutes and then the call gets disconnected (and it isnt my phone, which is working well).
same here when updating from 64.21.81 to 64.51.01 with fwdl18.104.22.168ww-20190524-1.
Holding OK and STOP-Button on starting brings me back to BOOT MODE - DOWNLOAD MODE. Then I was able to connect the firmware update tool again with the printer and sent 64.21.81 again. But even this ended with "Please wait ..."
Any help? I don't want to throw away working hardware because of software issues.
At last, I did it.
I had to load up new firmware 64.51.01 instead of trying to reinstall 64.21.81. Printer boots several times then - and is back to me.
