Ideapad 320-15ISK bios problem, old version needed 4WCN25WW

Dear forum,

 

I installed new bios from 4WCN25WW to 4WCN29WW on my Ideapad 320-15ISK 80XH but I forgot to save the old bios before it. After upgrade the laptop slowed down so I try to downgrade to the old bios but I cannot find it anywhere. Where can I find this version? Please help to find this bios version (4WCN25WW) or share it somehow?

Another question for this problem: I find a new bios in the support forum (4WCN36WW) but the Lenovo Companion didn't find it. Do anybody has information or experience with this bios version?

 

Thank you for any help in advance!
