Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

So where is the modded BIOS file you use for flashing? The zip file only has a small 46kb file in it to use with the second GPU. Sorry if this is a dumb question :(

- - - Updated - - -

What I'm asking is where do I find the file to use when YBIOSFix asks for modded BIOS file to use?

It's in the "ideapad y500/400 bios mods overclock out of the box" thread but here you go

http://forum.techinferno.com/attachments/lenovo-ibm/7504d1368808033-v202_1100mv_mem.zip

Your bios is already version 2.02, right?

For me, the perfect balance between temp and performance seems to be 1100 shader and 2500 memory. The max temp I hit on either card is 75 under full load (gt650m has max op temp of 105). Thanks again to svl7 (and zedster for getting me the needed bios link)!

You have to flash the second one using the oc.rom file from the first page (in dos). Then use nvidia inspector to overclock both cards. You select which card to chane the values for at the bottom in inspector. When done setting make sure you press apply clock values and voltages then for each card right click set startup shortcut and create one for each. Make sure you do this for both cards or when you restart the values will revert back to normal!

First of all thanks for these wonderful mods!

Also just wondering, if there is anyway someone could lift the BIOS limitation off when trying to mix and match the Ultrabay GT650m with the onboard GT750m and vice - versa because it gives me a unsupported VGA error.

Hi guys, I was just wondering if this unlocked BIOS will allow you to mix and match the new GT750m with the old GT650m.

I tried it with version 2.0 BIOS and it says Unsupported VGA card

I heard from Lenovo chat that the 650m laptops support a 750m in the ultrabay but not the other way around.

Hey guys, is anyone else having a problem when flashing the 650m sli? I flashed the latest modded BIOS and flashed the latest modded vBIOS for the ultrabay gpu, but I don't see the [MODIFIED] tag on the ultrabay gpu, and the clocks are unchanged as well. I get no errors and it seems everything flashed successfully.

EDIT: After a few minutes, the problem just went away. Huh.

One does not simply mix different GPU models in SLI

BTW, has anyone heard anything of svl7? He has been away for a long time now.

What is the max overclock you guys are getting without exceeding the AC adapter's power? I read someone had this aroung 1250mhz.. I cannot test this with my i5 setup.

Have people had OK results using the modded BIOS 2.02 from svl7's May 9th post?

Also, do I need to install the modded 650 SLI BIOS if I install the modded BIOS but do not plan to change the clock speeds on the GPUs?

TIA

I want the n5300 dual band 480 for this machine, I'm hoping to get an approved fru number.

After I flashed my bios with this unlocked version, I upgraded to a Intel 6235 with no issues. Bluetooth 4.0 works great and having dual band is nice. So if you have flashed your BIOS the FRU# wont mater anymore. I hope the Intel 7260ac releases so I can upgrade to an ac wireless card eventually.

I think I might be blind, but I can't find the answer to my question:

I've trying to create the modified bios from a backed-up bios. I run Y500BiosFix.exe, answer the first question with the backed-up bios bin file, then it is asking for a modified bios file. I'm running v2.02 after updating with the leaked version, but I don't see a modified v2.02 to use. I do see the v1.03 and v1.05 modified bios, and v2.02 stock.

What am I missing?

Check page 57 of this thread. Should be there.

Google is your friend. I googled remove whitelist yesterday and I found a tutorial on how to do it. It can take several days to figure out what to do to globally disable it. You can wait for svl7 to return and ask him. Send him a PM and wait for him.

Honestly I think it's not worth it to remove the whitelist. Just buy a supported network card and you save yourself a whole lot of trouble down the road if a BIOS update arrives and so on. i have a unofficial without the FRU. If I could choose again, I wouldn't buy one again. It's hardly worth it, trust me.

You better go with a external USB adapter with high range if range is a issue.

The WiFi bandwidth of a 150Mb/s is high enough anyway for these days. I have never exceeded it, NEVER. And I encounter so many different Wifi's everyday. The fastest I encountered was a 12MB/s, and even then achieving that speed is rare with other users on the network. And even then achieving that speed is rare. If your network supports it, then achieving 12MB/s on a download is even rarer. The only thing that was able to reach 12MB/s was the German Steam server, while I live in Belgium. Go figure that :)

But if u want the whitelist still, ask svl7. He's a pro. I just gave my opinion of my personal experience.

What kind of speeds are you getting with the 6235 and with what wifi access point?

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

      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!
