Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

Sorry bud, I honestly have no idea and I'm not using Windows 8 anymore. Don't think I'll be of any help. :(

If the BIOS flash wasn't successful, the system wouldn't even boot with an aftermarket wireless card installed.

I appreciate the reply. This is just irritating. I'm offering at least a $30 donation (enough to buy a good bottle of maker's mark ;) ) to anyone that can provide a working solution to the problem I'm having.

Does the WLAN card work in other machines? Have you tried using Driver Sweeper/Fusion to clean out the old wireless driver? Do a system image backup and reinstall the OS as a last resort? This way you can go back if reformat doesn't fix it.

I dun have the card, so this might not help much. But I read somewhere that Lenovo power management app can cause trouble, try uninstall it. If all method fails, do a backup and recover a clean os to know whether the problem is with the card. If you suspect it's the bios issue, revert to original bios and update to official 2.04 b4 modifying it. Hope it help

@svl7 I have mod my Y400 with your bios mod, Thousand Thanks! :chuncky:

btw, i have tried many configuration on bios, and i tried to enable Intel HD Graphic, I was able to startup without any boot problem, ONLY by set to " PCI " as primary display.

but, when windows done startup, i noticed that GT750M is not enable, and i was able to install Intel HD Driver. i think i'm running on Intel HD Graphic, but, with no driver, so, its a bit stuttering..

Here's some pic

Hi, I'm new here and I signed up because I was planning to switch out my stock wireless adapter to the 7260. I see your signature (or is that what it's called?) contains the Intel AC 7260 but through this thread, no post confirmed that you succeeded with the installation. How did you go through with it?

Is it an either or thing if you enable the intel graphics? or can you enable it for power savings on battery?

You cannot enable it, period.

I will try these both to see if they work. If so, you'll def be hearing from me and I'll buy you both each a few or more beers :) Give me a few days as I have drill this weekend, so I'll be packing, working, and getting ready for it.

Yeah, try what jamescc suggested. Flash the backup of your original BIOS, update to official 2.04 using this, and then mod it again. This'll put both BIOS and EC version at 2.04 as right now you have BIOS on 2.04 and EC on 2.02. Not sure if it'll make any difference but it's worth a shot.

Has anyone done this on a purely Linux system? I can make the USB and the customized BIOS on a Windows desktop, but I haven't seen much on grabbing the backup of the BIOS on Linux. I'm looking at flashrom now, but I'd appreciate any other advice/tips.

sorry, but just need a quick answer.

my current y500 is already running on bios 2.04. so its safe for me to just flash the modded bios using the normal method stated in page 1 right?

      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).
