Lenovo Y580 / Y480 'unlocked' BIOS versions

Recommended Posts

If you unlocked the bios and then got the problems, I don't think it's something at the hardware side. But you could try it of course.

Just wondering if anyone has the modified BIOS and upgraded to Windows 10. Any issues?

 

Should I upgrade to Windows 10 first and then upgrade the BIOS or should I upgrade the BIOS first?

Hi, 
I would never thought that i could face such issue, but it happened. 

When i was flashing new bios, my pc froze because of driver. Simple BSOD. Hard turn-off didn't work and i had to unplug batter and AC. 
Now after i boot my computer i see only keyboard lit, fan is now spinning, screen is black.

Any advice?

Problem solved.

 

Looks like modern BIOSes has some kind of fail-safe mechanism. It slightly differs from pc to pc, and for Lenovo Y580 it will be like this:

 

The main idea of this fail-safe mechanism is to record BIOS rom file on flash drive with proper name so recovery system could read it and flash once again.

 

1.       Download official BIOS from Lenovo Support page

2.       Unpack it and take .ROM file (mine was QIWY3207.ROM)

3.       Download a special tool that will tell you what name should be used for this rom file (http://forums.mydigitallife.info/threads/13194-Tool-to-Insert-Replace-SLIC-in-Phoenix-Insyde-Dell-EFI-BIOSes), every laptop has its own name.

4.       Tool told me that recovery name for QIWY3207.ROM will be QIWY3.bi? but that wasn’t working, so I made several files with names: QIWY3.bi, QIWY3.bid, QIWY3.bin, QIWY3.rom don’t know which one worked.

5.       Record files on flash (I’ve used 16gb formatted in FAT32)

6.       Now detach AC cable, all USB devices, SD card and battery.

7.       Plug in flash drive

8.       Press FN + B and keep it pressed

9.       Attach AC adapter

10.   Press power button

11.   Now FN + B can be released.

12.   Laptop will spin-up cooler and start reading flash drive.

13.   For me, it started beepeing horrible, I had to wait for several minutes and then turned it off manually.

14.   After this laptop booted without problem into windows, where I re-flashed bios in usual way.

I ended up just paying for it.

I'm having the problem of not being able to downgrade the bios due to having the more updated version.

I've changed the bios version check to 0, but I think it's having issues before that.

      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.
