svl7-I tried to download the mod bios without the WLAN whitelist to try and was not allowed too. I'm wondering if you are still testing it and will you make it available to the rest of us? By the way great work in unlocking the bios!

Nope, it's working fine, and it's attached to the first post, you should be able to download it. Public link coming soon.

Yeah it would :P Hahaha, I'll see what I can do.

Read the forum rules, you need 5 quality posts in order to download attachments. The unlocked bios is already available to everyone, public link in the first post. Whitelist bios will follow.

is there any kind of special flashers that we need to use this, or is the flasher bundled in the zip file? (sorry, haven't downloaded nor tried yet due to the fact that i'm waiting for further updates)

and also another question, would you be able to disable the intel hd 4000 and just use the nvidia graphics after this custom bios? i'm having issues with windows 8 where i can't control the brightness since intel hd 4000 is the main controller, nvidia has working drivers so i think that'll fix my problem if it is possible.

Just download it and read the file in there... it's all described.

And yes, you should be able to use the Nvidia card as primary device, but I'm not sure whether this will solve your brightness isssue, due to Optimus your system will always use parts of the HD4000 cause it's needed to bring the picture to the screen.

ah rats, guess i'll have to wait until Intel fixes it for Windows 8

I'll update my bios once a GHz edition for the video card pops up. I'm greatly looking forward to that =D

I get the following error "The version of rom file isn't newer than version of bios."

I have already installed your unlocked version, now I am trying to install the unlocked/no whitelist version.

Please advise.

Bought a 6205 card off of Amazon, do a search for product code B004NNZB4A, and swapped it in my Y580 with the unlocked/no-whitelist BIOS. Connected to the 5ghz on my WNDR3700. Works great and much better than the stock 2200N that was in here. Thanks again for your work svl7 on the BIOS and empirehell on your wifi card recommendation!

I installed the Lenovo Y480 / Y580 BIOS version 5DCN39WW (V2.06) [unlocked]. excellent! But there is a problem. I can not change the fan speed depending on the temperature. In the BIOS change but really do not.

There's a whole section for temperature and fan control on the new bios. Try peeking around more.

I agree. I have tried:

Low Speed/Temp 60%/70%/80% fan @ 40 C / 40 C / 45 C / 50 C

+

High Speed/Temp 100% fan @ 50 C / 55 C / 60 C / 60 C

There's a whole section for temperature and fan control on the new bios. Try peeking around more.

Do you say this because you found how to correctly control fan speeds and are being cryptic or have you not tried o.O

Not necessarily all available options will work, there's a reason why some of them are hidden. The bios vendor always uses the same framework, so there might be hidden settings available which don't work with your system.

Extract the downloaded file, it's packed in there.

Yeah .. like WOL wil never work..

the reason for that is that the motherboard in a shutdown state is not supplying power (even with AC on) to the network adapter so it can't be waken.

but options are in the bios.

I'm looking forward for a vbios.. thanks. svl7

Hi! I'm trying to install a 6205 and I want to install the no-whitelist bios

However, after unzipping and executing the file, i get a DC Detect error!

What am I doing wrong? :o

Do you have your AC adapter plugged in?

Yup! I haven't plugged in my battery yet, It's running on power.

Is it my power settings or something?

Ok, then plug in your battery as well, then it should work.

For security reasons you need both, battery and AC in order to flash, or you need to modify the flash settings in order to circumvent these security measures.

Be advised !

If you try to completely disable your INTEL video card using the new settings/options made available in the new unlocked y580 bios you will disable as well :

the laptop LCD screen and the HDMI port

since the lcd screen inverter and the HDMI output are directly connected/tied thru the motherboard to the INTEL GPU on the processor ... no bios option will be able to disable it properly because its not designed for that at the circuitry level

On this machine design you can disable the NVIDIA GPU completely but not the other one (the Intel graphics or IGFX) ... when all enabled the intel one manages the Nvidia and the switching goes on thru the optimus scheme implemented at hardware/driver level between the intel GPU inside the CPU and the Nvidia GPU

That's correct, that's also why I advise all users not to change anything they're not familiar with (first post). There are more options which can cause the system to not boot after changing them.

Intell Centrino-N 6300 wont work with this modded bios, it's install, looks like everithing well, but can't connect to any wireless AP.

I modified bios by replace some not used DEVID with 6300 DEVID and card run in proper.

Here is zip with ROM and InsydeFlash Y580_n6300wifi_whitelisted.zip

      Required items:
      1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
      2.) 65CN99WW unwhitelisted.
      3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
      4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
      5.) ATX power supply (I used a 600W PSU from another computer I had).
      6.) USB wireless.
      7.) External monitor, keyboard, and mouse.
       
      Steps:
      1.) Obtain and install a unwhitelisted BIOS. If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with Tech Inferno Fan's Setup 1.x (may need confirmation as I haven't used it myself yet.)
      2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
      3.) Remove mPCIe wireless card and detach antennas.
       
       
      4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
       
       
      5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
       
       
      6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
       
       
      7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
       
       
       
       
       
      8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).
       

       
      9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
       
      Extra Info:
      I found that most games will play on med settings with about 45 FPS with this particular card.
      BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
      Skyrim: Med-High settings.
      Fallout 4: Med settings.

      ok, so, i have a serious problem atm.
      im trying to mod my bios so that i can go past the normal overclocking limit. however, everytime i try to do it, it always says "file size does not match existing bios size!", and it's really annoying, since i had to find everything myself, as no one else online tried this on my specific model, besides me. (which surprises me, really)
      this is the guide im following:
      So this is my detailed description how I managed to mod and overclock my GTX 960M in my Lenovo Y50-70. Please note: it is very dangerous to play with the BIOS, so you need to be very careful! I take NO RESPONSIBILITY for any damage or misuse of the information below! Use it AT YOUR OWN RISK!
       
      -------
       

      Necessary tools:
      A. Fptw64 from Intel (9.5 or above)
      http://forum.hwbot.org/showthread.php?t=75024
      B. PhoenixTool (2.50 or above)
      C. Maxwell II BIOS Tweaker (1.36)
      https://www.techpowerup.com/downloads/2562/maxwell-ii-bios-tweaker-v1-36/
       
      -------------------------
       
      How to flash Modded BIOS:
      0. Flash the latest (3.03 now) official BIOS
      1. From Windows, start 'cmd' as Administrator and read your your BIOS via Fptw64:
         Fptw64 -d BIOS.ROM -bios
      2. Reboot, enter your BIOS and check "Enable downgrading BIOS" feature (we need to downgrade first in order to flash the modded BIOS)
      3. From Windows, downgrade to 1.13 (this is necessary because the newer BIOSes have protection against mod-ding)
      4. After reboot & reflash, start Windows, then enter standby, wait a bit, then wake up the machine
      5. Create your modded BIOS, see separate list below
      6. Start 'cmd' as Administrator and write your _modded_ BIOS via Fptw64:
         Fptw64 -f BIOS_MODDED.ROM -bios
       
      -------------------------
       
      How to create modded BIOS (point 5 above):
      5.1 Start PhoenixTool.exe from Phoenix Tool 2.50 and open your previously saved original BIOS.ROM from point #1 above
       .2 The tool analyses it and shows some messages, click OK
       .3 Now you can find your vBIOS in the "DUMP" subfolder in the folder containing your BIOS.ROM, with the file name:
          BE13645B-2C2C-44D2-A64F-0EA052C34597_1796.ROM
       .4 Create your modded vBIOS, see separate list below -> let's call it 960M_OC.MOD
       .5 Click on "Structure"
       .6 Open "EFI BIOS" tag
       .7 Open second "File Volume {7A9354D9-...}" tag
       .8 DXE Core -> Compressed Section -> Raw section -> File Volume {7A9354D9-...}
       .9 In the very long list, find the following tag (usually displayed at around 80% of the list):
          Freeform {BE13645B-2C2C-44D2-A64F-0EA052C34597}
          This is the item containing the latest vBIOS
       .10 Open the tag, then "GUID defined section", then click on Raw section. "Internal number" (in the top right corner) should be 1796 for BIOS 3.03.
       .11 Click on "Replace" and select your modded vBIOS (called 960M_OC.MOD above)
       .12 Click exit "Exit" and say Yes to "Save changes?"
       .13 Close the Phoenix Tool; now you should have your BIOS.ROM updated (the original will be saved as BIOS.ROM.OLD for safety)
       
      -------------------------
       
      How to create modded vBIOS (point 5.4 above):
      Use Maxwell II BIOS Tweaker to change BE13645B-2C2C-44D2-A64F-0EA052C34597_1796.ROM;
      5.4.1 Open the ROM
         .2 Change "Boost Clock" on "Common" tab to the new boost-ed maximum value
         .3 On "Boost table" tab, use the slider in the right bottom corner to increase your max boost-ed value to the same number
         .4 On "Boost states" tab, at P00 profile, change the MAX values in the GPC, L2C and XBAR fields to the same max boost-ed value
         .5 Save your modified BIOS and rename it to 960M_OC.MOD
       
      (My boost-ed max value was 1359 MHz. I could then use MSI Afterburner's software tuning -> my 960M could reach 1454 MHz without voltage increase.)
      i know that it's for a different laptop, but its basically the same
      ill provide more info when im home

      Hello,
       
      I want to share the modded Bios I created for the Acer Aspire E5-572G notebook.
      The official bios 1.09 was used as a base.
      I'm offering three flavours: Microcode 01, Microcode 07 and Microcode 21.
      Microcode 21 is the latest available microcode, this is the Bios you want to use unless you want the special properties of the other microcodes.
      Microcode 07 is the latest microcode that allows using the full turbo clock speed on all cores (using single core turbo with all cores).
      Microcode 01 is the one you should take if you want to try this. I wasn't able to get it to work on mine (i5 4210m, HM86), but your mileage may vary.
      In case you want to always use an older microcode, I'm offering a script for windows that'll keep the OS from using a newer microcode (compatible with Windows Vista to Windows 10). Frequency and other things can be set up with ThrottleStop (use the latest version).
      I've also included an overclocking enabled ME firmware that should (hopefully) allow overclocking on the HM87 equipped notebooks.
      There are two flavours of this notebook available: Ones that use the HM87 chipset and others that use the HM86 chipset. Overclocking is only possible with HM87 as HM86 isn't capable of overclocking (tested it myself).
      Additionally I offer a collection of Bios, EC, ME and FD files of this device, in case anyone wants to experiment with these for a bit (EC Modding, etc.).
      I will update this bios in case there are newer parts available.
       
      Any feedback is welcome!
       

      Features:
      -Advanced Bios Options unlocked (Advanced, Power tabs and additional options in the existing tabs)
      -Nvidia 840M/940M VBioses replaced with adapted 940MX VBios with unlocked TDP Limit, unlocked Boost Table and some OC (1306,5MHz GPU/1070MHz Memory - with general usability in mind) + all voltage sliders unlocked
      -Intel Management Engine: Updated to 9.1.37.1002 + All Locks Unlocked + Overclocking Enabled For HM87 Notebooks + PAVP (Protected Audio/Video Path) Enabled
      -Flash Descriptor unlocked
      -Microcode updated to version 21 (respectively downgraded to 07 and 01)
      -Intel GOP Driver updated to 5.5.1033
      -Intel VGA Bios updated to 1042
      -Intel RST OROMs updated to 15.1.0.2545
      -Realtek Lan OROMs updated to 2.037/2.64
      -Applied a few useful BIOS patches by CodeRush (Unlock CPU Power Management Register (useful for Hackintosh Users)/Disable BIOS Lock/Disable SMI Lock)
       

      Flash procedure:
      1. Copy the BIOS file to an empty and with FAT16/32 formatted usb stick.
      2. Unplug the AC adapter.
      3. Remove the battery of the notebook - you can unlock the battery on the backside.
      4. Plug in the USB flash disk.
      5. Press and hold <Fn> and <Esc>, and then plug in the AC adapter while still holding <Fn> and <Esc>.
      6. Press the Power button. You can now stop holding <Fn> and <Esc>.
      7. The BIOS flash should now begin, the fans will spin up at max speed and the power led should blink. It should take between one to two minutes.
      8. After everything is done, you can reinsert the battery and go to the BIOS (F2). There you may want to change some settings (the BIOS flash erases all previously chosen settings).
