Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

Yeah, will put it up in an hour or so. Can you (or any other 2.04 user) do me a favor? Some users seem to be eager to update to 2.04, this might be possible with your help. PM me if you want to help. I completely forgot about this, wanted to do this a while ago already.

If you can figure this out, it would be nice to know what changes 2.04 brings over, say, 2.03 and 2.02, and what hardware (750M and/or 650M) is supported, since Lenovo doesn't bother to provide any of this info.

v2.04 added. Only for 2.04 users at the moment, I'm looking into providing an update for the rest.

Can someone with a 750m please post a picture of 2.04 showing the overclocking part of Nvidia Inspector?

v2.04 updated, corrected something I forgot.

If anyone is seriously interested in going to v2.04 coming from a different version please let me know. Else I won't bother wasting time on it.

BIOS Upgrade - ThinkWiki

flashing EC

http://www.msi.com/html/pdf/How_to_make_a_bootable_flash_disk_and_to_flash_EC.pdf

According to MSI admins you cannot backup EC.

Bios and EC update?

So probably it's not possible at all.

Of course it's possible, I'm just not going to waste time on it if nobody is going to use it.

I know others have expressed interest in upgrading to 2.04. As for me, I would like to know what changes are in 2.04 and whether it supports 650M, as opposed to just 750M. If nothing is different or better then I won't bother.

Update to 2.04 for all v2.02 and v2.03 users. Should work flawlessly, I still have no machine to test it myself but I see no reason why this would cause issues.

Let me know if all is fine.

EDIT: See first post for files.

Hi,

Do I need to go to stock v2.02 BIOS first, or can I go from modded v2.02 to modded v2.04?

Greetings,

Is it safe for gt650m sli users?

Just performed the upgrade.

I used my original v2.02 (stock) backup file for your BiosFixer_2.0.exe utility.

It created the v204mod.bin file just fine.

Flashing from DOS worked fine too :)

The only thing which is a bit strange is that in the BIOS setup, it still says v2.02.

Is that as intended?

Thanks and greetings,

What does this new modded BIOS version fix?

Oh, hehehe, my bad. I can fix that, but it's not that important. Can you post a screenshot of the inspector showing the overclocking stuff?

Fixed 2.04 version added to the first post, will work for 2.02 and 2.03 users.

People with older Bios versions than 2.02 should use the unmodified update to 2.02 and can then still proceed to 2.04 modified.

Just finished updating/flashing. Actually, I was trying to download the 2.02 modded version when you were updating and it kept failing until I reloaded the page. Anyway, straight forward and no problems whatsoever.

I wanted to comment about post-flashing. This took a solid 18 seconds off my boot time to the desktop and about 10 second of the complete load (ie. background servers finished). I didn't modify anything in the BIOS yet, just looked around. Not sure why or if it was supposed to work this way, but I have a definite zip to boot and even running apps within Windows, compared to before.

Thanks a lotǃǃǃ

There's a new update that Nvidia is notifying me about, but I haven't installed it. Also, didn't play around with any settings yet, but hope it helpsǃ

      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!

      NVIDIA 'Maxwell' VBIOS mods
       
       
      Here you find modified VBIOS versions for the mobile parts of the Nvidia 'Maxwell' series.
      The VBIOS versions in this post are tweaked for performance and versatility. You'll get almost complete control over the performance parameters of your GPU.
      List of available VBIOS mods:
       
      Nvidia GTX 970m - 'OC edition' rev0 - >> 6 GB Version << - modified by @johnksss & svl7 -> see attachments Nvidia GTX 980m - 'OC edition' rev0 - >> 8 GB Version << - modified by @johnksss & svl7 -> see attachments  
      Screenshot demonstrating the capabilities of the 970m versions:

      >> Read the instructions carefully before flashing! <<
      If anything is unclear after reading or if you have additional remarks, please post in the thread.
       
      Flashing:
       
      - Go to the device manager -> 'Display Adapters' -> chooser your GPU, right click on it and choose disable
      - Flash the VBIOS with mnvflash, a modified version of nvflash (see attachments). Here are detailed instructions for nvflash in case you aren't familiar with it.
      - After the flashing is done: Enable the GPU once again in the device manager.
      - Reboot
       
      Do NOT use driver 347.09, it's broken and useless and won't allow you to overclock, even with the stock firmware.
      Don't distribute the files hosted here outside of Tech|Inferno. Don't modify the files you download here.
       
      Donation link in case you want to buy me a beer

      Thanks and cheers!
