Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

I am gaming with my cpu at 60-75C now and GPUs in the 60ies.

I really hate the summer.

Hah, my old laptop (C2D and 8600m) I was gaming on 100cpu and GPU in high 90s, so I'd say those temps are quite awesome. :P

Right now I do not own a laptop cooler and I was wondering what would be something good that you would recommend. I am currently looking at buying this one Cooler Master Notepal X3 Gaming Laptop / Notebook Cooling Pad Up to 17" (200mm Adj. Fan Speed) - Newegg.com.

I would like to know if there is something better out there that may cool better. I do not mind the price as long as its under $80 which it should be.

Hi guys, I just upgraded bios to 2.04 and vbios for 650m SLI. How do I use Inspector. Which preformance level should I use, there is 3 to choose? Which settings do u have for everyday use without cooling pad for the laptop?

  • Download the modified vbios and put it on your USB drive as well. Rename the file so that the name has no more than eight characters (not counting the extension). It's a DOS limitation.

Dear svl7, unfortunately the link is dead :( Could you please upload it again?

Your BIOS patch is perfect!

Any of these would be more powerful and cheaper. Just be careful not to kill yourself with the aluminum ones because they have razor sharp corners.

Logisys Computer Wind Pal Black Laptop Cooler Pad Model NP88BK - Newegg.com

I got the last one and it's pretty good. Moves a lot more air than my old Cooler Master pad, although the plastic is a little bit flimsy. But it's lightweight and I can actually carry it around in my laptop backpack without weighing myself down or being afraid of impaling myself LOL.

The modded vBIOS files for the Ultrabay 650M and 750M are in the attachments.

Anyone know how to disable 'secure boot' in the moded bios? Cannot find that option there.

Secure boot option disappears if you turn on Legacy Support instead of UEFI.

I am currently on modded v1.05 BIOS with non-stock WiFi card. From what I read here I have to upgrade to v2.02 stock BIOS first then apply the mod. I assume I will not be able to boot up after upgrading to v2.02 stock as I have non-stock WiFi card installed, please let me know if this is correct. Thanks.

After updating to 2.02 stock, you can simply go into BIOS and disable the WLAN card. That will allow you to boot up and flash to 2.04 modded. Then you can go back and re-enable WLAN.

I don't see anything mentioned about LOSING features with this mod. Does anything not work afterwards? I would just really like to upgrade to a newer Wi-Fi card.

Also, if I have zero interest in OC'ing my 650 SLI, can I ignore the flash for the Ultrabay card?

Thanks!

Since updating to 2.04 modded, has anybody else noticed that the screen now has an auto-brightness mechanism that will dynamically adjust the amount of backlight depending on the displayed content? So it will brighten if light content is displayed and dim when dark content is displayed. I have tested this thoroughly and swear it wasn't there before when I was on 2.02 modded. I'm extremely sensitive to these kinds of visual stimuli and noticed it right away. There seems to be no way to turn it off either since the adaptive brightness setting in Windows power options doesn't do anything on this laptop (the laptop doesn't physically have an ambient light sensor). I'm not too annoyed by this new feature but just thought it was interesting to note. It sure would be nice to be able to turn it off though.

EDIT: Scratch that. I just rebooted and now the auto-brightness bug is gone. Weird. I did have a BSOD earlier today so maybe that had something to do with it. Anyway, ignore what I wrote above, nothing to see here.

Can't thank you enough SVL7. Being limited to 2.4Ghz WiFi as a serious downside to a laptop that otherwise blows me away. BIOS flash worked great, just ordered a new card. I threw a little money at your new laptop, thanks again!!!

No it will not work. It is for Y500/Y400 only.

I say be patient and it should come. svl7 is too busy at the moment. He's the only one supporting this laptop and many others with all these incredible BIOS mods so give him some time.

You need 5 (4 more to go) approved quality posts to become full member with download/PM/... privileges. Or you can become T|I Elite member with even more privileges.

You might want to read the forum rules for more information.

Thanks Re-Reading the forums rules instead of skimming them this time. Just bought a lenovo y500 / 750m and want to unlock this bios mainly cause of the whitelist on the cards. Laptop has such potential but the stock wifi really holds it back....Does anyone know who is the actual creator of the modded bios? Definitely want to throw him some brew/bojanglin cash for the mod. I've seen the original thread by sv17, but others are taking claim for it on lenovos forums and 1 other guy on a Russian forum...

Apparently there is a bunch of speculation behind this laptop and locked features....LENOVO Y 400\ 500 UNLOCKED BIOS -FULL WIDI ,RAID,S... - Page 3 - Lenovo Community

My y500 seems to be different from most peoples that post specs.

I bought mine online on memorial day 2013 which came with v2.04 bios and with WiMaX but it say drivers are missing another big difference is my y500 has the nvidia 750m....

Bios is still locked up though....

@svl7 is the creator of the mod. He's got a donate link in big letters on the main page of the forum. If someone else is stealing his work and claiming it as their own, that is a very serious thing and you should message svl7 (he is a mod here) or one of the other mods so they can investigate and take action.

Your Y500 is the refreshed 750M model and is a common configuration that a lot of other people also have. You'll have no problems upgrading to the modded 2.04 BIOS.

I agree with a lot of the other posts on here, This laptop is quite powerful, but has a number of lenovo influenced limitations like the wifi. I hope this mod will solve my problem using a new Centrino 6300.

Another quick question - I read in the earlier part of this forum about somethings not working. I am only looking to use the mod for removal of the wlan whitelist. Has anyone had a bad experience or loss of functionality from this mod that would make using it not a good idea? I use this laptop routinely for work, and would hate to find out that my video cards work poorly now, or something like that.

Thank you for that information, Is there any idea when one will be available for this notebook, I really like it but the wifi limitation really sucks on this from Lenovo.

Don't worry, the mod is better in every way. :)

      Hello there!
      I am new on the forum. I'd need some help. I own a lenovo ideacentre t540-icb g, and i would need to unlock all the options in my bios, especially overclocking and thermal configuration. I tried with both amibcp and mmtool, but i didn't succeed (Error 18).
      I wonder if you could help me or give me some advice.
      Thanks in advance.

      Hi,
       
      I need help in fixing my Thinkpad.

      I just got a T440p yesterday. It was working perfectly until the following:

      I reinstalled Windows and then I installed Vantage.

      I installed all the latest drivers.
      I also choose to install the bios update. The bios update ran in Windows and it asked me to restart. After restarting, the screen was blank. I tried powering it off and on and I saw the Thinkpad logo but after that the screen was blank.

      I tried powering on and off again and there's no Thinkpad logo now and the screen is just blank with the green power on. No sound, no nothing.


      Here's what I tried:
      Pressing the power button 10 times and then holding it for 30 seconds. Unplugged and battery is detachted Detached the CMOS battery and the reattached it Removed the ram, harddisk and optical disk drive. Attached the battery and inserted the charger. I turned it on and there was a couple of beeps Tried pressing FN+R and created a bootable USB I'd like to ask: How do I fix this? What do I need to do?
      Can I reflash the bios in some other way? Do I need to buy a new motherboard? Will this solve the issue? It's my first thinkpad and I'm really excited but I was bummed out that this happened. Can you please help me?

      Thanks in advance!

      Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!
