Lenovo Y580 / Y480 'unlocked' BIOS versions

Recommended Posts

Hi I'm new to bios unlocking but pretty experienced with building computers and computer in general. I have a Lenovo Y480 and a 640m Le in it. I would like to overclock it. Do I need to unlock the bios in order to do that or can I just use nvidia inspector or msi afterburner? I have 5dcn40ww which I understand is version 2. What is the best option to unlock the bios? Upgrade to 8 or stay at 2 and how would I do that. Is this unlocked bios compatable with 640m le and will I be able to set my own clock speeds, memory, etc? Thanks in advance for the help.

The confusion around SSD caching in Y580/Y500 (same chipset) is big, since there are several technologies involved. There are Intel Rapid Storage, Lenovo RapidDrive, Lenovo Expresscache, Lenovo RapidBoot and Intel Rapid Start. (Some may not be avaible on HM76) I have no idea which are differences beetween them or how to configure any of them. It would be nice to understand how to use aany of them with my 32GB SSD.

Pretty confused :ambivalence: ...

Thank you !

As for Lenovo RapidDrive there is an instruction at Lenovo web-site: http://78.9.150.202/pub/RapidDrive.pdf which explains what RapidDrive technology consists of and how to enable it after fresh install or reinstall on Y580.

Thank you all for anti-help! All done without your help.

Thank you so much, svl7 for your efforts! Good work!

Good day to you! I suppose we have the common problem. At first I also was angry since there where no reactions when I call for advice. I think we can help each other. As I have read you have BIOS v.8.00 (5DCN89WW), right? Me too. Can you precise what is configuration of your Lenovo Y580 (CPU model, OS Installed)? And if it is possible can you explain in what way you have been able to solve the problem. Also I'll interesting to know about licensing information in BIOS, is it rest untouched after flash or not?

REDRagnarok (and for everyone who does not speak English), i have Lenovo Y580 with i5-3210M, RAM 6Gb, HDD 1Tb, preset Windows8, BIOS v.8.00 (5DCN89WW). I did so:

1. create a backup of your bios (BiosBackup.bin)-see the first page.

2. Put the files in a single folder (Y580-Y480_BiosFix.exe, BiosBackup.bin, v800.bin (from the archives of "Lenovo Y580 - Y480 BIOS v8.00 (5DCN90WW) - Mod.zip") and do fix for their version of the BIOS.

3. Flash BIOS with v800Fix.binpost-12050-14494995007484_thumb.jpg

If you used fparts.txt file from the folder "'Error 104' - fixed", the same file to use when flashing a new BIOSfix. Before flashing a new BIOSfix necessarily run the prr.exe!!!

licensing information in the BIOS is still intact!

Hi

im new here and so glad for registering in this forum

i want to flash unlocked bios for first time and i have some questions

1 i have the old config of y580 with windows 7 and 2.x bios.so can i use the 8.x version?

2 if the first answer is yes : any problem or unstability after doing that?

3 you told that the graphic clock is tweaked to 1GHz so what about the lenovo energy management software?! is it always 1GHz or only when we use the "dynamic graphic" option in the lenovo energy management?

1 - Not yet, but I'll see that I can upload a proper v8.01 update soon. Most things are ready, just need to find some more time.

2 - Newer bios - less bugs (usually, lol) which means more stability. Though you might not even notice a difference.

3 - You don't need that software, really. The card will only run at 1GHz when running 3d applications on the system.

Please someone help me , I wasn't able to recover it from the Fn + B with no battery method ( It reads my pen drive but just once , no copy or any signal after . I don't know the correct name it has to be , to restore it).

Please help ! Thx in advance

I've already update the Bios from V2.07 to V8.01 and everything goes well since now.

The EC version would remain V2.07 while the Bios version is V8.01.

Also the Win8 License is Invalid as there is no license in the original V8.01

You can just find the solution in the old post of this topic.

You just need modify the file platform.ini and try again.

The Notebook runs for only a few seconds, then it restarts and then it turns off. I don't understand how to use this solution.

Hi Svl7,

I am still not able to backup my bios. I have not attempted it for a while (had given up) now I came back to it because my network speeds are horrible with this stupid stock wifi card. I was able to do it before but then had to ship my laptop into Lenovo because the hard drive controller fried out. When I got my laptop back they had replaced the mother board with a similar one and I attempted to hack the bios again this time with no luck.

Whe

I did everything like the instructions stated and now came across a new error. I got ERROR 360: Invalid Block Erase Size value in "fparts.txt".

I have no idea what to do next. Any ideas?

Thank you,

Update

I am back to getting Error 103 again!

Is it correct that BIOS V2.07 doesn't support my CPU i7 3630QM and V8.00 does?

I think that's the reason why i can't use the recovery BIOS from the lenovo page?

Where can i find a recovery BIOS for V8.00?

Ahh... one little problem. I successfully flashed 8.01, but then messed with something in the unlocked menus, now only get black screen. No POST, or hard drive access after initial spin-up, it's stuck before the bios.

I've read about recovery, and I'm trying some solutions now. I have a y580 with windows 8 preinstalled, trying to recover my old bios. I did back it up, and I have tried to find the filename I need for insyde recovery, but I'm not sure if I'm doing this right. Any help would be very appreciated!

Update: Fn+B seems to put the laptop in some recovery mode, the fan goes crazy and it does seem to have some effect, but I'm not sure which BIOS version/ROM version to try to restore.

Try QIWY3.bin as filename and use your backup file if possible.

Or if you think the system still boots then you could try to blindly boot into Dos and flash it blindly back.

I'll try that, as soon as I can get it to turn back on at all. I tried to take it apart to remove the CMOS battery, but realized it's pretty deep in there. Putting it back together right now, wondering if there's a screw that needs to be in for it to power on...

Update: I've managed to put it all back together, reset the CMOS, and I tried using my backup rom. It didn't work, I'm going to try a few more bios versions, but I do know Fn+B is the correct recovery method. I've tried the backup file and the windows 7 bios, and neither seems to be working. Really hoping to find a solution soon >:

I've tried QIWY.bin/rom, QIWY3.bin/rom, QIWY4.bin/rom, and none seem to work.

First Download Phoenix Award BIOS Flash Tool.

Second Open It And Choose Your Bios It Will Give You Your Bios Name That You Shall Use For Recovery After Phoenix Award BIOS Flash Tool Loads.

Third Format A Flash to fat16.

Fourth For Example My Recovery bios name is "QIWY3.bi?" As We Know "?" Character Is Invalid So You Use ALot Of Extension.

Fifth Downlaod The Bios From Lenovo Site.

Sixth Copy the bios to your usb and name your extension as following "keep trying every extension tell it works"

"QIWY3.bi , QIWY3.bi.ROM , QIWY3.bin , QIWY3.fd , QIWY3.rom" Until It Works :)) , I ALready did this in my y580 :)

EDIT:- To Enter Recovery Mode 1st:- Remove AC AND BATTERY

2nd Insert Your USB TO THE RIGHT USB PORT

3rd Keep Pressing FN+b.

4th While You Are Pressing FN+b Power On Your Labtop and plug your AC.

5th if you hear a beeb remove you fingers from FN+b

6th you will hear 12 beebs or more it wont stop so you have to wait and hold your ears for 1to3 min after that you manually shutdown you labtop and you are done :))

      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).
