I have a question regarding "resetting the device to factory state", more exactly - cleaning up the eMMc after installing the OS there or reinstalling it with clean image. How can it be performed? The only idea that came to my mind was installing the clean image to eMMC once again from SD or USB but when I tried it, I got a message with no space available and the process has been broken. Any help would be appreciated!

But you can boot from USB/SD card and format the eMMc and then install the image again. So follow the instructions but before executing the dd command to write the image to eMMc you can do: mkfs.ext4 /dev/mmcblk1 Best regards!

I have tried putting the mMC and the STAT LED stays in red. If I remove it, the LED does not activate. I have also tried it with a USB stick.

So I directly repeated the instruction again: dd if=/home/IOT2050_Example_Image_V1.0.2.img of=/dev/mmcblk1 bs=100M conv=fsync status=progress Since then, she no longer responds. If I insert the microMC and turn it on, the STAT LED stays Red If I remove the microMC and turn it on, the STAT LED does not light or blinks fast red. As a team it is not a prototype, but it came in the box without S.O.
