Thanks for this great forum

 

I recently bought a Y500 and need to flash away this locked bios. This post looks to have the information and tools I need. I look forward to becoming a full member.

Hi, all! I was able to successfully flash my bios some time ago; I noticed that the integrated Intel graphics controller now shows up in the bios, and in Linux; however, trying to activate it doesn't work because while it's there Linux (PopOS!) can't seem to set the backlight level on acpi:video0. I'm thinking there's a mismatch in the eDP/LVDS settings, but I'm not sure what to try. Has anyone gotten their Intel graphics working in a flashed IdeaPad Y500 with GeForce GT 650M SLI?

Hi!

If you have this error:  

Error 28: Protected Range Registers are currently set by BIOS, preventing flash access.

Please contact the target system BIOS vendor for an option to disable Protected Range Registers.

 

Then download archive Prr.rar from this link:  https://files.fm/u/qfpmwzpsh

Extract this archive, then put both files ( prr.exe and Flash.bat ) into your USB flash drive (where contain your bios file and fpt utility).

Rename your file v204mod.bin  to bios.bin

Then boot from your USB flash drive in real DOS, and execute command:  flash

My bios version is the v2.04, is there any way to use the downloaded bios instead of the original one from the laptop?

Hi!

No, to prepare unlocked bios, you need to use your original file bios dump from your laptop.

Hi, I'm trying to dump it but I'm getting the error 75 fparts.txt file not found. But the file is there!

For creating backup of bios you can use attached utility. Extract attached archive directly on the Desktop and run utility as Administrator (right click mouse, choice "Run as Administrator"). Utility will create archive "results" directly on the Desktop. Post here this archive "results", or upload it into any fileserver and send me the link.
