Restoring my old bios version

[DJxMizo]

Hi guys,and thanks for taking some time to read my post..
I recently flashed my bios,with a version I found on lenovo's website,and it works pretty good,but the only problem is that I noticed a decrease in gaming performance.The software I downloaded from their website is called WinPlash64,and it suggested that I make a backup of my bios version before flashing it,and thats what I did,now I do have the backup file,its called ''FLASHABL.bak'' but the problem is that I dont know how to use it..Please help me ! thank you again !

My laptop : Lenovo ideapad u450p

there is a folder named bios on c volume ( c:/bios ) it should be a file called bios.bak. rename it to "newbios.wph" and process the bios update again.

Hi and thanks for answering ..

When I go to C drive,I can't find the folder called bios,I have to go to :  C/temp/bios202 and then,I find some files like bios.wph and winphlash64 and some others..

Plus the backup the software made before flashing is called FLASHABL.bak , not bios ?!

thanks for the answer =)

According to your reply,will naming the backup the software made before flashing from FLASHABL.bak  to  newbios.wph and putting it in the software folder (bios202) solve the problem ?
