- Software you need
Go to https://etcher.balena.io/ and download balenaEtcher. If you are Windows user who’s already get used to Win32DiskImager, it is also fine.
Prepare the EMMC Module
1.Get the EMMC module
Remove the bottom cover of the KINGROON KP3S Pro V2 printer, then you are able to see the EMMC module.
Loose the screws on it, remove the module carefully.
2.Get everything connected
Connect the module to the EMMC adapter and SD card reader, as the photo shows. Be careful with the directions. Then you are ready for the next step.
Flash the EMMC Module
1.Setup balenaEtcher
Connect the SD card reader to your PC or Mac, you should be able to see a disk named “boot”, that’s the EMMC module. If not, please check the connection and make sure the direction is correct.
Open the balenaEtcher, choose the image file you just downloaded, and click flash. Please double check the disk you choose, in case you lost any data.
If the disk disconnected in the middle or the flash failed, please use a different SD card reader.
Once the flashing finished, you are all set. Just put everything back, reboot your printer, and enjoy the 3D printing.
What are the types of SoC? What are the exact product names? There is a serious issue with u-boot. I can fix this.
“I also need a board replacement. I’ve tried applying all the firmware, but only the text saying ‘loading’ appears on the screen
I purchased kps3spro-v2 in May 2023 and have not been able to use it due to a breakdown.
failure symptoms
1. When you turn on the printer, the screen displays only Loading.
What to do
1. I tried to update the firmware, but the screen only shows loading.

→ FYI

https://drive.google.com/file/d/1Bs7II2rqlCsdqx6EUUGfDOED4BwqQK0y/view?usp=sharing -- I can’t download this…
2. Ali Express sent me a motherboard and replaced it.
→ The menu screen is displayed normally on the screen.
→ The z-axis, automatic leveling, and shaper were performed normally.
→ If you select an output file during test printing, you should return to the main menu and operate it, but there is no change on the screen.
→ If you come out of the usb folder and enter again, a file called start printer is created. If you click this, there is no change on the screen. But no output…
→ So I installed the firmware 20230322 again, but the screen only shows loading.
Please tell me what action to take.
