After that, I removed the jumper and restart the module, but it stays in recovery mode - OS does not boot, the screen does not work, USB is defined as “NVIDIA USB Boot-recovery driver for Mobile devices”

I tried to flash different images, different versions OS - nothing changes. How to fix?

Previously this module was flashed Linux, and that worked fine

One thing you may try is completely erasing the NAND flash from within Linux. Just re-install Linux or at least the U-Boot boot loader again and execute the following within the U-Boot serial console:

Colibri T20 # nand erase.chip

That will completely erase the whole NAND flash chip and hopefully allow you to re-flash WinCE/WEC again.

Thanks for the reply, but is there not a simpler way exists? I tried to reinstall Linux on Colibri, I did not succeed. I know nothing about Linux and I have no computer with Linux.

What exact module version do you try to flash?
Please make sure you are using the latest NVFlash Tool.
Could you try once to flash a 1.4 final version. Please make sure you are using the updated versions of the .cfg files. We have updated all the image versions with the new files. You find them all here.
