VIM3 Doesn't boot anymore - neither from emmc nor from SD card

VIM3
1

Hi, I have a VIM3 Pro, and it doesn’t boot anymore, both from the emmc and from the SD.
I tried to boot oowow but it doesn’t work that too, and now I don’t know what to do.
The only thing that it does is that the white light turns on static.

Can someone please help me?
Thank you very much

EDIT: I tried to enter the Upgrade Mode by the buttons and it showed a cyan screen with only this lines:

And it continued to write this lines

@SpheLC which firmware was last installed to the eMMC ?
Have you tried flashing firmware through the usb-c directly ?

Hi @Electr1, thank you for your answer!
By “firmware”, do you mean OS or something else?
If in doubt, I’ll tell you:
The last thing I did was install Ubuntu 22.04, and after two reboots, it no longer started.

And, about the USB-C flash, it gave these errors:

Hi,

could you please try this image - https://dl.khadas.com/products/vim3/firmware/ubuntu/.test/vim3-ubuntu-22.04-gnome-linux-5.15-fenix-1.6.5-240515-develop.img.xz

You can write it to sdcard - either using balena etcher, raspberry pi imager, etc or extract and then dd it to sdcard. Then insert the sdcard to vim3 to boot from the same. Once booted, you can use the following command to install it to emmc.

sudo emmc-install

Follow the prompts. Once its done, power off vim3 and remove sdcard. You should then be able to boot from emmc.

Thank you very much! It worked!
