Lenovo Y580 / Y480 'unlocked' BIOS versions

Recommended Posts

First of all what are your CPU and GPU temps? This could be caused by many things... You could run a prime95 test to see whether the CPU might be the culprit, if it isn't then a fresh installation of your OS might help.

Right now I'm running Prime for 40 mins.. Temps are 84/83/82/79°C And thats the max temp. GPU is getting after hard O/C about 80°C.

I will try installing the OS on some other HDD to NOT lose my data.

Do you think I should install a copy of Win7 from some other source/drivers from some other source?

I'd like to test something, if anyone's with a Y480 / Y580 is willing to help please let me know. Nothing dangerous, just want to try to get a dump of the complete firmware.

I have Y580 and will gladly help you :) Just tell me what to do.

Hello Svl7

I finally took the adventure to flash your unlocked V8.01 version and it works!

It is amazing that I have the bios version of V8.01 and EC version of V2.07.(None of Win8 License in bios)

I just used the dos command flashit xxxx.rom /MC /BIOS.

My machine is still in warranty and I think Lenovo customer service can just help change the mainboard if I crashed my machine.

So I get my target finally.

Anyway,thanks a lot again for your hardworking

If your system still POSTs then I'd say try to blindly flash back with fpt, else there's really only the recovery method. It's described somewhere at the beginning of this thread if I remember correctly, including key combo.

So your bios bricked my computer. I've been speaking with some people and they are telling me Lenovo uses collpsable bioses. IBM is not your average laptop company, they make sophisticated hardware. Fortunately they will repair it for some 150$ bucks...

Warning: fn-b recovery methods for the y480 may not work. Trust me I have been trying for days. Use this bios at your own risk.

Is it really sophisticated, or just crippled? I'd say if it is locked down and hard to tweak, it's crippled... not sophisticated.

It is sophisticated AND crippled. The reason they white list is for monopoly. If Lenovo can guarentee Intel that their laptop will only support Intel wireless chipsets, then they will discount their prices. Those discounted prices are how Lenovo sells it so cheap. That's why its the best cost to performance machine you can get right now. The manufacturer, the old IBM guys, are smart cookies, and they are still building these things. Ideapads are crippled... AND sophisticated.

I'd rather say that your user error bricked your system... The bios itself is totally fine.

Sorry to hear that you can't recover, if you're still under warranty you should just send it in and let Lenovo handle it.

Seems my bios is pretty popular on the Chinese ideapad forum...

Flashing directly per Dos with flashit should work yes, but only when coming from v2.0x.

Yes, your BIOS is popular on ideapad.it168.com. I've been searching for posts related to installation of third antenna and accidentally found out some appearences of some modified BIOS with references to this post... Congratulations, BTW !

One question, what are the improvements of the V8.01 BIOS ? Seems like late production models with WIN8 are shipped with it but I wasn't able to find out the list of improvements since the V2.07. Anyway Lenovo should post it at official support page soon.

Thanks!

Fair enough, I bricked my system, but the fn-b bios recovery method is not something people should seen as reliable. Lenovo said they would fix it. Knowing me ill probably try and flash it again haha,

Svl, Is it true that if your default bios is 8.0 you use the 8.0 mod and if your bios is 8.1 you use the 8.1 mod? Just trying to define my error so I avoid it next time.

So I did everything as explained, and it the bios flash worked. I restarted the PC, changed a few things (nothing important, besides enabling the Intel Virtualization something (I can't remember the exact name)) and when I restarted again, the PC won't boot anymore: it just keeps restarting (turning on and off) before it even gets to the Lenovo screen. I tried removing the battery, without success.

Any hopes for me? Did I brick the BIOS? Should I just give it to tech support? It occurred to me that perhaps removing the CMOS Battery and rolling back the BIOS configurations would maybe work, but I couldn't find it. I read in someplace that it is below the touchpad, can anyone confirm if that's true? Thank you very much and I apologize for the desperation! haha

I got the same Problem like okaybr right now. What should I do?

Hey svl7, I'm running 8.01 and willing to do a favor. The only problem is I have yet to get your BIOS to work. I am getting stuck at the "create backup" part. Whenever I run the backup.bat file, a command prompt window flashes and that's it... I really would like to get this BIOS working but alas, I am a college student with finals coming up and can only tinker on my laptop for so long.

Cool, I'll send you a PM with the details, stock BIOS will do the job.

As for creating the backup... you need to run the cmd as admin, go to the folder where fpt is, then open a cmd window with admin privileges there and then type backup.bat and hit enter, that should work. If you have a crappy AV software then you might also need to disable it temporarily since it could block the PCIe driver.

Hello. Anyone able to get the Intel Rapid Storage Technology working ? It was mentioned briefly on previous posts. It seems like Lenovo is using some sort of software RAID. But the process isn't very clear.

- HM76 chipset supports RST (via intel ark info)

- But there are no RAID option at original BIOS.

- Modified BIOS shows a RAID option, but not like one of chipset modes.

I just want to buy a small, cheap SSD and use it for caching the HD.

Any ideas ?

I have encountered a problem with the GPU clock staying at 1000mhz. While playing BF3, for some reason the clock does not want to go above 924 mhz, dipping low and returning up to that point, all indicated on Afterburner. Would their be a way to lock it at 1000mhz?

http://imgur.com/ovvBWZW

This shows the fluctuating core clock, the mem stays put. Could it be somehow linked to the temperature?

Hmm, I don't have a Y580 to test this... do other users encounter this issue as well? Please let me know guys, then I can look into it.

Also... is that your temperature there, the column with the 90s values? That would be pretty hot, really...

      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).

      In this thread you can post your requests for Lenovo G580 (20150) and (2189), G480, G780.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
       
      For prepare unlocked bios you should post your request here and then send me your file backup of bios via PM.  For creating backup of bios use attached program. Extract attached archive directly on the Desktop and run the program as administrator (right click mouse). Program will create archive "results" directly on the Desktop. Send me this archive "results" via PM.
