EDIT: I linked the guide for reading and learning, not to take guidance from other users HW and bios protected values examples, as its not equal to all.
Lets say, that what a beginner user calls bios/rom, in these days its more called an SPI FIRMWARE system image, so your system as most of all, have protected areas on it that doesnt allow some operations to be done.
And as a beginner that you are…be very careful as this is not common tools/operations risk safe, advanced user experience is a must, and the risk of fail operations is always present.
In the thread you shared , He said : “Notice that BIOS/UEFI is not locked by the Flash Descriptor and thus OEMs are responsible for implementing BIOS-specific read/write restrictions such as Protected Range Registers and so on. That means that the Flash Descriptor is not responsible for any read/write restrictions set at the BIOS/UEFI region of the SPI chip, so the FD-related methods below will not be of any assistance in such cases.”
and my problem here is the Protected Range Registers and the Flash Descriptor has nothing to do with it as he said , right ?
Yeah , true …
I think I’ve to go to a technical support center to flash EEPROM (because I don’t have any programming chip + I can’t risk doing it myself).
But I wonder if there a way to change S/N in a low level (without flashing BIOS) where Windows can read it differently ?
@sergeyshibaev228
I have the same laptop with same model , with the same BIOS version EGCN29WW.
the flash command always fails with Error 167 : Protected Range Registers …
So how does it work for you ? Did you flash the EEPROM ? or What did you do ?
Have you tried first switching off laptop. Then pressing and holding these 2 keys simultaneously: "Win" and "R"… while keeping them pressed together, press the "Novo" button on your ideapad… then go to the BIOS option and you should see the advanced options you need…without having to flash
At least it works on my G580 (20150) with BIOS 5ECN96WWV9.01 I hope you have the same success.
Hello, I want to undervolt my CPU (GPU also if possible) on my Ideapad 3 but all options are disabled in ThrottleStop and there are no advanced settings in the BIOS. Can someone help, thanks.
Greetings to the friends of the forum. I don’t know if I posted in the correct place, but I would like a modified lenovo gaming 3i bios for my notebook with Advanced Settings with RAM speed control to overclock.
The bios version is EGCN39WW, as per the official website link: BIOS Update for Windows 10 (64-bit) - ideapad Gaming 3-15IMH05, Creator 5-15IMH05 - Lenovo Support US.
Thanks a lot! God bless ya.

I tried to mod my bios. i cannot create a backup of my bios from FPTW.

Since there were a lot of separate threads about the exactly same topic, I have merged them all.
Unfortunately the Forum software didn’t put them into the correct chronological order and I don’t know how to solve this problem.
