Warning - The settings stored in EEPROM are not compatible

I have a Monoprice Maker Select Plus 3D printer. I was able to update the LCD without issue to 4.0.5. After I restart the expected configuration\navigation screen displayed on the LCD. It looked very good.

I figured at that point I should update the mainboard firmware. I have tried via Cura 4.5 and Arduino. I made sure baud set to 115200 on USB2 and USB3 ports (each time I try different combination). I have tried 3 different USB cables. USB cable is only 1 meter. I have updated\reinstalled the USB driver from the forums here. I disconnected and reconnected the LCD cable to the mainboard. The LCD cable looks ok.

Each time the flashing says it is successful but after restart I get this warning message. The right arrow to continue does not allow me to continue but touch screen seems to be working fine. The previous mainboard firmware appeared to be working, but I did not save a copy before flashing as I did not intend to revert.

Any suggestions to resolve?

TIA!

I found wanhao i3+ I3_plus_V3.0.hex firmware at http://wanhao3dprinter.com/FAQ/ShowArticle.asp?ArticleID=79

I flashed it and LCD is working now. I would still like to update to ADVi3++ firmware though. I then try 4.0.5 firmware upgrade and it still stuck on that screen. Is there some configuration I need to modify?

This happens typically when the flat cable between the LCD panel and the mainboard has moved a little in its sockets and thus the firmware is not able to communicate with the LCD panel. The fact that the touch screen reacts is normal, this is handled by the LCD panel only.

Then probably when you have refreshed, the cable has moved slightly again. It happened to several people in the past.

So I suggest to check the cable (both sides) and flash again.

I flipped the cable around, making sure to maintain the same direction of the connection. Flashing worked the first time. This leads me to believe there is something wrong with the cable though, I’ve ordered a new one. They only come in packs of 10, so if anyone else needs one, PM me.

@andrivet My Monoprice Maker Select Plus uses a Type B FFC, like this: https://www.amazon.com/gp/product/B07RT6YRWR/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 150mm length, 1mm Pitch, 10 Pin

Your wiki page links to a Type A cable:

Just providing extra information in case others run into the same problem.

Yes, it depends of the model of the LCD panel (there are at least two different ones). I will modify my document as you suggest.
