Finally, I succeeded in installing TWRP.
When opening, he asks for a password for decrypting.
No idea so I canceled.

Then he asked for unprotecting systemfiles and I answered YES.

Then re rebooted, but even after factoryreset, the screen says:
Orange state, your device will boot in 5 seconds.

That's all. He's not going further.

I'm happy !.

I searched for "unbrick Oukitel K5000" and after many scared minutes, he's working again !!.
 

For others: use flashtool and install stock rom. After that, reboot and be very patient !!!.

Oh, and power down, and press Volume UP !!!.
on different sites they say to press other buttons, but no, Volume UP !!!.
