Here is an easyer way to enter download mode :
1. device off
2. connect black(gnd) and green(D+) wires of usb cable (you just Can peel it off no need to cut wires)
3. connect micro usb to your phone and in a few seconds disconnect green from black wires
4. wait a sec......and everything ok you will see ......qualcom 9008.....etc
This is our "beta" version of cable....
It worked! I used the cable method, I did it a little bit different, but it worked and now I my Redmi S3 is working again
I say it was a little different because I connected the USB with the copper wire, I removed the USB (and copper) and connected it again in the other port next to it without the copper and the device was recognized as Qualcomm 9008 :3
Thank you so much!
