Khadas vim3l Doesn't turn on

I apologize for my English, I recently installed Armbian but I didn’t like the performance and using it and I couldn’t uninstall or install another operating system, I tested Android and it didn’t work.
Using OOWOW it said there was no space, within the OOWOW settings I deleted the emmc partition thinking it would work
In a simple way, I deleted the emmc and my khadas won’t start or boot from the pendrive/sd
The program to install the systems on the computer does not work, it only goes up to 2%,
Can anyone help me please, I don’t know how to use this equipment and I was studying to do some projects
In its current state, it has the white light on and does nothing and does not give any signal or blink.
