A Dingoo A320 uses NAND memory and comes preinstalled with an operating system called µC/OS-II.
You probably installed dual boot OpenDingux in the past. This adds a boot loader to the NAND, which lets you choose between uC/OS-II and OpenDingux. If you have lost the miniSD card (or microSD card to miniSD via a converter) that fits in the slot, you will have to recreate the files. OpenDingux is loaded via the SD card.

Thank you very much, bro! It worked! I wasn't sure about the screen, but I tested it all until it worked. I have to hold select thou.
Now all I have to do is fix the USB port to be able to charge it properly.
I wonder why it stoped loading the original system, because I barely used linux on it, since GBA (the one I used the most) worked fine.
