Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

anybody have a good recommendation of a WLAN card with bluetooth card to use in a Y500 after removing the whitelist? I'm hoping for a 450Mmbps.

thanks

Correct me if I'm wrong, but that requires 3 antennae doesn't it? To do that you'd need to find a place to run a third antenna wire. Intel 5300 cards are 450mbps, but from photos they look to be a triple antenna model.

Here's an example photo:

Well, I just wanted to chime in here and say "thank you" to everyone who made this thread what it is -- especially svl7! Everything worked nearly flawlessly (I ran into a hiccup trying to install Windows 7, in that the OS simply would not boot, no matter what I tried), but I'm now all configured and rolling smoothly on a fresh Windows 8 install! I played Skyrim with HD textures and a bunch of mods, and stock, I noticed a slight bit of lag every now and again; however, overclocking the GPUs made all the difference! For the cost and everything, you simply can't beat this setup (I have the 650M SLI model, BTW). I upgraded mine with 16GB RAM and a 240GB mSATA SSD as well, so it's definitely running smooth as silk. =)

I paid the $5 to have access to the files herein, and on top of that, though it's not much, I just donated $10 to svl7 for making this all happen.

Thanks again, everyone! I'll be keeping my eyes on the thread and contributing wherever I feel I may be able to. Oh, and one thing of note is that my BIOS for this system (Y500 with 650M SLI and 8GB RAM), which I purchased on Newegg about a week ago, was version 2.00. Like a dummy, I was too hasty and flashed over it, so I don't have a copy of it. Either way, I thought it might be worth a mention!

If you are still interested in installing Windows 7. It could be due to the fact that your booting in UEFI and not legacy mode. I couldn't get Windows 7 to boot from a USB disk until I did that.

Thank you Svl7. The instructions were easy to follow and made the flashing process easy.

I've tried UEFI win7 and it DOES NOT work. Legacy works fine as you'd expect, but UEFI just won't work. The furthest I got was installing OS, booting into Safe, but locking at CLASSPNP.sys. I'm guessing there's some incompatibility, but what do I know...?

your HDD must be formatted to a GPT partition, I had this problem as well. After thats done you can install Windows and uefi will work immediately.

Am not an expert with laptop oveclocking, but as I used to work with phones SOC on XDA, we used to downclock the cpu and the gpu to increase the battery life, although the phone one can be done on the fly from within the system and according to battery levels, so my question can we do this over in this laptop, especially after lenovo ruined the intel 4000 dreams maybe we can use the 650gt at very low, still stable, voltages to be able save battery when not gaming for example (can't try not enough posts to download) so if someone could try or maybe provide personal experience

I asked this a bit ago but after some searching I don't think it was ever answered. Does the modified BIOS have a setting for turning on and off the charger?

It's doable yes. If you know Windows.

You create the necessary power schemes.

Next up.

Know where the power schemes are stored in registry and know how to use the command line to change power schemes.

Next find a way to read the battery levels.

It's all you need. Plain simple. ;)

To help you:

HKEY LOCAL MACHINE// services ? // CurrentControlSet // Power

I think that's where u find it. Not sure.

There are keys to turn off and on hyperthreading, control turbo boost, control upthreshold and downtreshold and so on.

dont waste your time on it. :bananahuge:

Great, working on it right now

found something in HKEY_LOCAL_MACHINE/HARDWARE/DEVICEMAP/VIDEO

maybe this is for the video card, am not sure will keep searching and will try different combinations, and want to ask since seems that the macbook retina is very similar to the lenovo y500, so may iatkos work on this (provide a link to thread if available I know am in wrong thread) Just for the sack of experimenting I am not that much into hackintosh but would like to have it on this machine

My machine has bios v.2.03, is it safe to flash it to 2.02? Or is there some other steps I need to do? Thanks

Will it be a problem if I have the bios normally associated with ELAN touchpads but have a Synaptics? I got the touchpad replaced, but they didn't replace the bios.

The only way to get everything working is to update bios? Isn't that too dagerous? :D

Can I dual-boot Ubuntu and Windows 8 after bios upgrade?

Thanks for the answers. ;)

The BIOS mod doesn't disable anything else other than the whitelist - it should be noted, though, that it'll purge all your settings. You might have to fiddle again with the knobs for EFI.

@caweek I do not think that the touchpad is affected by the BIOS, well you don't even use it until the windows kernel loads and loads either the windows driver or the associated driver, am pretty sure it wouldn't matter and the biggest proof they didn't even change the bios and it works (assuming they meant it of course)

hi. I try to flash the bios but I do not.

I did that :

  1. download the modified 2.02 bios
  2. made a backup of my bios with "Universal BIOS Backup ToolKit 2.0"
  3. fixed the bios with the y500fix tool.
  4. I put on the usb stick the fixed bios , the prr tool and the fpt.exe with the text file (was located in "dos version")
  5. I restarted on USB and try to flash with this command line : fpt.exe -f filename.bin -bios
  6. AND... Have error 28 : the bios is protected from flashing, contact your manufacturer. or something like that

An idea?

In the tuto the files where in bin extensions. my bios is in rom..

Where is the modified v2.02 BIOS?

I can see the v1.03, and v1.05, but there doesn't seem to be a v2.02 on the first post.

can this mod activate Optimus?

No. Optimus is hard-disabled for the feature use of SLI in the Ultrabay.

      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!
