Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

@octiceps, amazing, it works! thanks a lot. Had no idea that borderless makes the jittering go away. However, running it in window doesn't affect the priority of task for the CPU?

Follow the instructions in the first post and use the prr tool I wrote to get around this issue.

Missed that. Sorry. Worked perfect. Thank you!

Not sure, but it shouldn't affect anything. I've had no problems so far.

Dammit...

My Y500 is refusing to detect the before-detected external ODD and there is no thorough drive menu in the default BIOS... Will this modding be a help there?

I'm currently running the modified v2.0 bios. I need to return it back to stock but cannot find my backup.

Does anyone by chance have a copy of the original?

Or another "stock" bios that would be safe to flash.

Thanks in advance

Everyone's "stock" BIOS is different because it contains your Windows activation, Lenovo serial number, and UUID. I'd suggest contacting svl7, maybe he's got a way for you to return to stock from your modified BIOS even though you've lost your original backup.

I was just wondering: is it true that the unlocked bios has absolutely no impact on fan speed even though it has the options? Is there any possible way to control the fan manually?

Thanks, good news is I believe I've found my backups so about to try and flash it back...

Knock on wood....

Florin, there's this tool I use called Process Lasso, which let's you automate certain CPU related tasks (like CPU Priority/Affinity). For instance, when I launch Star Wars: KOTOR or System Shock 2, I have Process lasso automatically set to change the CPU affinity to just one core (those games don't really handle multicore well and crashes/locks up). When I launch GTAIV, Process lasso changes the CPU priority to above normal so that GTA IV is given the most attention. This makes it so that I no longer need to mess with Task Manager after launching games.

If you're concerned that running in windowed mode take away cpu priority, you could always counteract it in this way. If you don't want to download a new tool to automate, you could always Ctrl+alt+delete and change the CPU priority to high manually.

Yes you need to update to official 2.02 first and then to modded 2.04.

I plan to update msata dsik to 120gb, should I wait to update disk before bios or after. Or it has nothing to do with this?

No, this will only work with the Lenovo Y400/Y500.

Could anybody please advise, whether after patching BIOS there appears an option to switch off SLI? It looks like without switching it off MacOS is not able to be installed on Y500...

Will this work with Gn36 750m?
No, this will only work with the Lenovo Y400/Y500.

GN36 is the part number for the Ultrabay SLI card.

This BIOs mod will work for your card.

Thanks!

I just set a new 3dmark record :pride: although It did not save to my account because I did not delete my previous one and I did not pay for the pro version; and for some reason it was submitted twice. Anyway here is the link.

NVIDIA GeForce GT 750M video card benchmark result - Intel Core i7-3630QM Processor,LENOVO INVALID

Nice, that's pretty awesome. With my 650M SLI my highest is P5228, currently sitting at #3 on the list for 650M systems. Clocks were 1260/2250 @ 1.137 V. Not practical for everyday usage because the GPU's will get up to 97-98 C and start throttling, so I use it just for benching. At my everday clocks of 1120/2250 temperatures are 20 C lower. It's crazy how much extra heat is generated when you bump up the voltage.

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

I really hate the summer.

      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!
