    Some more, When you do the screen cover turn on method described above, after 20 seconds a white writing Update mode appears, however, if you keep holding 10 more seconds after the power light came on, a red wrting appears for IPL Update mode. I could not do anything with it, trying to run the European firmware updater mentioned above. Error shows File not found. and all buttons flash. I then covered the Speaker button (touchscreen buttons!) for 10 seconds and it showed the installed ROM Versions. Like I said, I was not able to change anything, but maybe it helps the tech guys form inkchip.net to know that there is a second level Updater. (If that solves the problems they seem to have, I would appreciate getting the chipless for free 😉

    This instruction for changing printer into firmware mode works on WF 3820 as well, but it is tricky. Took me severl trials. the impoortant part starts at 4:05 minutes into video. For me worked best to put thumb downwards diagonal.

    The european firmware is here, but it does not change the required cartridge number to 405. And it is a relative new version, so might look to Epson original. https://download.ebz.epson.net/dsc/du/02/DriverDownloadInfo.do?LG2=EN&CN2=GB&CTI=63&PRN=WF-3820 Series&OSC=WS I changed the firmware several times via USB cable and putting th e printer into Firmware mode by holding thumb on upper right corner of display, kind of diagonal from up down, covering about a square inch including black fram around display area in upper right corner.

    Unfortunately it is not enough to put European Firmware on Northamerican machine. I have tried that and it still wanted 822 cartricges instead of 405 for Europe. So I rolled back to American older Firmware from this link https://dl.resetprinters.net/index.php?act=dl&id=7071&hash=1628480254460#google_vignette which allowed me to use thrid party 822 cartridges.However, you need to change the chip every time they are empty, and the chips cost about 27$ per set or 10$ individual at Aliexpress.com plus shipping from China and customs duty.
