Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

A final dumb question - does anyone happen to have a copy of the legacy Y500Fix? I'm flashing one of jester_socom's custom BIOSes but can't preprocess it since the only files being distributed are per-version versions of the Y500Fix - presumably with specific BIOSes embedded inside.

You mean svl7's old command prompt BIOS Fixer tool? I have a backup of it I can send you but I'm away from my computer right now so it'll be in a few hours. svl7 can probably provide it too.

That's the one - it let you input any file so so wished, if I remember - thanks in advance.

That version is outdated. It has an issue and mustn't be used anymore.

My hands are bound, though: I've got one of jester_socom's custom BIOSes, and no means of doing the necessary fixes on them.

What was wrong with it? I used it to flash three different laptops without problems.

the bios flashing is a success! man it's like a whole new world blasted into your face with this mod, so much locked stuff! :Banane17:

BTW @svl7 you should specify the vbios flashing that you only need to flash the ultrabay cpu on sli models aka <1> to avoid confusion

and can i change how my laptopperforms in battery? like removing the 135 idle speeds of the laptop onbattery

I haven't been able to successfully flash the newer 750 bios on the ultrabay card.

I get the following result when calling "nvflash -6 -i1 vbiosOC.rom" This is in the windows version 5.134 as 5.128 refused to even attempt flashing and said I needed a newer version to flash that firmware.

NVIDIA Firmware Update Utility (Version 5.134)

Checking for matches between display adapter(s) and image(s)...

Adapter: N14P-GT (10DE,0FE4,17AA,3802) H:--:NRM B:02,PCI,D:00,F:00

Current - Version:80.07.95.00.1A ID:10DE:0FE4:17AA:3802

GK107 Board - 2044nb3q (Normal Board)

Replace with - Version:80.07.9D.00.11 ID:10DE:0FE4:17AA:3802

GK107 Board - 2044nb3q (Normal Board)

Update display adapter firmware?

Press 'y' to confirm (any other key to abort): y

The display may go *BLANK* on and off for up to 10 seconds or more during the up

date process depending on your display adapter and output device.

Identifying EEPROM...

EEPROM ID (C2,2012) : MX MX25L2005 2.7-3.6V 2048Kx1S, page

ERROR: PCI Block corrupted - size mismatch

I am able to flash the previous version of the 750 firmware, but it doesn't seem to remove the 135 limit on the ultrabay card so I flashed it back to my original vbios.

Anyone else have any trouble with it?

Also considering purchasing the Killer N1202 to put into my Y400. It came last month with version 2.02 installed from Lenovo. Just to clarify since I am a computer noob. If I download the modded version 2.02, this will allow me to add the killer N card to the machine without issues, correct? Thanks again. Great mod.

Works well. I made a few stoopid mistakes like not pressing enter after running prr but she's done good now.

did you enter [ nvflash iX -r] before flashing the vbios? i had problems when i didn't enter that command before flashing. and please check if the vbios you have downloaded is the correct one

Yeah, I used the -r command first. Like I said, I can flash one of the two 750 firmwares, just not the newer one. The one I can flash doesn't seem to remove the 135 limit that I can tell.

Can anyone bypass the idle speeds of the GPU's in battery through the BIOS? i want to run it at least at 300/600 so that i can play at low settings on battery. This laptop is awesome but we should game a bit on battery not always chained to the power outlet

Try the latest nvflash: http://forum.techinferno.com/nvidia-video-cards/3827-latest-nvflash-windows-dos.html

Not very healthy for the battery, but Nvidia Inspector will probably allow you to do so. It's not a good idea for a bios mod to change the 2d profile because it will drain the battery a lot faster even when not gaming.

Does it allow you to overclock the P-state which is used when you're running on battery?

I have been reading a lot of questions regarding how to over-volt. However with this mod would it be possible to under-volt the 750m? The main reason is I don't have an AC, it hot these days and would prefer a much lower idle temperature than 50C! I think the cards are more than enough to run the games I play even at a lower clock rate.

excuse my ignorance, can i unlock bios and whitelist without OC video card?

You don't have to overclock the video card if you don't want to, your choice.

you can underclock via MSI Afterburner and Nvidia Inspector even when not modded (correct me if i am wrong)

My SLI had stopped working after I installed the mod. Although I had no OC plans I actually ended up installing the modified vbios as well which didn't help.

Anyway all I had to do was go to NVIDIA Control Panel > Set SLI & Physics Configuration > Disable SLI and then set it back to Maximize 3D Performance. Just putting it out there incase someone else gets the same problem.

I tried a cursory search but couldn't find an answer - does the unlocked BIOS have hot plug options for the sata ports? I turned my ultrabay into an eSATA port, which of course works with a drive connected/powered on boot - but if I can enable hot-swapping, that would definitely make it more convenient. Since this is the only feature I'm interested in, I'm reluctant to flash my BIOS sight unseen.

      I have a iBuypower CZ-17 laptop, with a 2012 AMI BIOS that has E1762 as the version, which I believe means I have an MSI G70 motherboard. It has a 675MX GPU, but it's not useable in Windows 10 despite being "seen" in the device manager. I believe an updated, unlocked BIOS would fix my issue and have located the thread on this site with the BIOS I need.

      First of all, am I right? Will this fresh BIOS make my laptop that originally ran Windows 8 work with this old GPU?

      And second, I created this account, will wait 24 hours and made this post. Is that enough to allow me to download the file, or do I need to post elsewhere?

      Thanks!

      A part of my BIOS got corrupted that controls my laptops backlights. Other methods like the Gary Key fix did not work for me because I do not get any light up during post. i followed this guide  that says I need to extract and use the 6MB portion of an 8MB bios dump, only AFUWIN tells me "Error, ROM file size does not match existing BIOS size which is because my laptop BIOS size is only 5.87MB.  I don't need to flash the whole BIOS, I only need to flash a portion of it. 
       
      I've searched everywhere online for a dump of my laptop model but non exist that I know of.

      I fiddled around with modding my laptops BIOS to unlock XMP profiles and hopefully seeing if optimus could be disabled. After flashing my modded bios and trying it out, I noticed that my keyboards backlight no longer turns on. I was unaware it requires an official BIOS to function. They backlights wont turn on unless ASUS ATK package is installed but now it seems it also needs an official BIOS?
       
      The modded ROM and tool I used if anyone has any experience with this and doesn't mind telling me what to enable/disable, or anything else i can do to re-enable them

      Hello !
      I tried a tutorial on the forum to remove the supervisor password on a X260 thinkpad but the winbond 25Q128FVPQ chip is not recognized with the programmer CH341A and ASprogramer (does not detect automatically and not manually). Plugged into the motherboard with a soic8.

      Can you help me with detection?
      Can I find the password with the software or do I have to write it?
       
      Thank you so much !!!
