First sorry for my bad English !
My printer is a Wanhao I3 plus and I always use it with the oem firmware since 2017.
Yesterday I casually go on the wanhao website and I noticed that there were a firmware update for the board and for the LCD.
I’m quite a beginner on the electronic part of the printer but i decided to upgrade both.
First I update the board (from Cura with the USB cable) and everything goes fine; so I proceed with the LCD a the trouble begin !
During the flashing the LCD brick and also with the original “format” firmware provided on Wanhao site it remains bricked.
Casually on google I discover this site and I find the same issue on one old topic; so I decided to join the community and try to update LCD and board with the 4.0.5.
First I start with the LCD and everything goes fine (the “brick” disappear); then I update the board (always with Cura) and also here the procedure goes fine.
The problem actually is that if I power on the printer the LCD remain stuck on the “3D printer image”.
I’m using Windows 10 and I follow the user manual provided.
It’s seems to me that maybe I’ve two problem: LCD brick (but solved with the 4.0.5 upgrade) and LCD stuck on the boot image (i read that could be the board that is rebooting continuosly because it could’t talk with the LCD but in this case my connection via USB cable works fine so I think the board is working correctly).
Thanks in advance for your support !
