In the root of an SD card and an USB disk i've placed the following:
- The last update.img downloaded from the last link you've send.
- A folder MCUUPDATE with file AndroidMcuUpdateA.bin inside, like shown in the your picture.
- A folder update with the 9 nine files/folders inside, like shown in your picture.

I've tried to execute the steps you provided ("Then turn on the device, then insert the USB disk to the USB slot, use a sharp thin sticker to hold the RST hole, press the power button three times and try to go to the recovery system."), but nothing happened.
I've tried this with the USB Disk and with the SD card, but the result is the same, nothing happens.
Can you send me a video of the process for my unit?
I see that the pictures you've send are from a different unit than mine. My unit is a CASKA CA712-Xl7, in the ebay announcement the refered model is 22-RD0258.

Please, i need you to answer clearly to this questions to try to understand what's happening:
1) The solutions provided are really the correct ones to my unit (CASKA CA712-Xl7)?
2) What are the factory steps to get to the recovery menu in my unit (CASKA CA712-Xl7)? Looks like the real problem is that i could never get into the recovery menu in any way!!!
3) An SD card or an USB disk with update files are a requirement to get into the recovery menu, or it's possible to get into the recovery menu without it?
4) What is the correct structure of folders and files that should be in the root of the USB disk or SD card?
@uudruid74, i've also tried the steps you've provided, and i realized that maybe there really are 2 logo screens, i always though it was the same because when i click the power button the same picture is shown, only the brightness changes. Anyway, i've tried your instructions, but i cannot get into the recovery menu anyway :
