Lenovo Yoga 710-14ikb bricked while BIOS downgrade

[mariomc]

I am too much of a noob here and its been a long horrible day of intensive research, I will be as short and clear as possible and hopefully someone could help in some way.
Totally my fault I for some reason shut down the laptop when I thought the installation was completed. 
Now the laptop wont boot, not even to BIOS menu. 
For what I have seen the first steps would be to create a bootable USB with the BIOS bin file. I used innoextract and then 7zip and got a bin file named CIUY7201. I formated a usb with the name CD_Crisis through Diskpart and pasted the later .bin file there naming it also CD_Crisis. After pluging it in the laptop I tried all the possible shortcuts that I found but no one worked. 
I am completely lost as to what to do now.
The BIOS chip is the windbond 25Q64FVSIQ in case it helps. 
I thought about buying one BIOS chips from ebay and soldering it but I don't know if that would work.
I have also read here about using a EEPROM reader and extracting the old version and fixing it but again this goes well beyond my knowledge.
Any help or advice will be more than appreciated.
I atached the bin file which I managed to extract and linked the lenovo BIOS drivers download page and the thread in Lenovo´s forum that I tried to follow to fix it.https://forums.lenovo.com/t5/Gaming-Lapt...=1#4178802
