sarthak Posted June 7, 2014 Share Posted June 7, 2014 Even though i downgraded Bios version 3.05 to 2.07 with all the correct instruction I am still not able to unlock the bios 2.07 by using the biosfixer.I have gone through every process correctly.Set my boot legay, enable back flash and so on. Disconnected all un-necessary USB devices , Connected both AC and DC powers, Eliminated all the non-windows applications.I used Bios 2.07 (http://forum.techinferno.com/lenovo-ibm/5405-please-make-modded-y510p-bios-based-74cn44ww-v3-05-a-2.html) To downgrade Bios 3.07..I made a back of it and modified it through Biosfixer for version 2.04 and 2.07.I used correct command to flash the modified bios with cmd.The bios was downgraded to 2.07 but i can't see any of the unlocked features.. Its the same features like before (v3.05) Quote Link to comment Share on other sites More sharing options...
