i have a question about firmware, a while ago i installed a new motherboard (4.2. 7) and a new hotend (spider v3) on my ender 3 pro, for that i installed the firmware "Ender-3 pro 4.2. 7mainboard--High Temperature Full Hotend Kit firmware" and everything works perfectly.Now i'm going to renew the display by a Touchscreen Upgrade, Ender 3 and i also have to install new firmware for that, if i do that i will lose the previous firmware (especially for higher temperatures)
