Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

Hey guys I have the Y400 with the GT 750m and I really want to get rid of the centrino 2230, is this method recommended for my y400? I was reading the main post and it said it was also valid for the Y400, but I'm not sure if it'll work with the 750m edition (the method was made originally for the y400 with the 650m onboard)...

You can install a 6235 Advanced-N Centrino if you disable fast boot on Windows 8. Else you will have BSODs.

If I were you I would go with the 6300, which does not have Bluetooth. And it's also officially supported. No need for BIOS mod with this one.

I'm really hoping for a 2.04 release, I want to instal an Intel Wireless AC-7260 in my Y500[h=1][/h]

The 6300 is supported but it needs to have the approved FRU, which I'm not able to find anywere... are you sure it'll work without modding the BIOS? Also the 6300 uses 3 antennas... and I really don't know where would I put the 3rd one (I don't know if it has to be put in a specific place or something, I don't want to mess up with the notebook too much)

The 6300 is supported but it must be the one with the approved FRU, which I can't find anywere, I don't know if the other 6300s with different FRUs will work on the Y400 or not, but also the 6300 has 3 antennas, but I know that it'll work with 2 (I'm not sure if putting a 3rd antenna will be worth it and/or if it has to be put in a specific place). Are you sure it'll work without modding the BIOS? If that's so I'm instantly buying the 6300, I don't care much about the Bluetooth.

What is the advantage of the 7260 over the 6235?

I had a 6300 in asus g73j and all I did was buy the 3rd antenna and coil it up in a vacant spot that would disrupt anything, and I got consistent 270-450mbps

If you take a look at that centrino 6300 it has the FRU # 60Y3193, and the 6300 that is "approved" by Lenovo has a FRU # 20002323 which apparently isn't anywhere! Or at least in all the sites I've looked on...

I just noticed this too. Where is the modded 2.02 bios? I suscribed just to download that file and now is gone :(

Right, I forgot to put them in the first post.

I revised the bios fixing tool, should be easier to use now since it's no more command line based.

Gonna add it to the first post now, v2.03 coming soon as well.

v2.03 mod added to the first post, please report any issues.

The 750m vbios has been updated in that version, if you're an SLI user you might want to flash the ultra bay card as well. Check the first post for the updated vbios.

I'm really hoping for a 2.04 release, I want to instal an Intel Wireless AC-7260 in my Y500

Please send me a copy of your 2.04 backup, I don't have a copy of that version.

Just so you don't think I blew you off bout the 2.04 bios, I didn't, had to send my Y500 back due to defective screen, I will send you 2.04 as soon as my replacement arrives.

Thanks

These ebay intel cards are usually engineering samples, with modded bios, ignore the fru, my y470p has the stock bios and I put a "supported" 6250 in it and the printed fru does not match the supported list O_o

Hello svl7,my bios is v 2.00. Is it possible to mod it? and why does my y500 freeze in metro 2033 and needs to be hard reset if i overclock it beyond 1050/2400 in nvidia inspector but i can overclock it to 1100/2500 in bioshock infinite without any problems

My nvidia driver is up to date, v320.18

Update to v2.02 and then use the mod.

Seems like your overclock is not stable for metro. Bioshock is a totally different program, it's not surprise that the overclocking results are different.

I just installed the 2.03 mod and can confirm it worked. I didn't realize just how locked down the existing bios was until I saw the unlocked one. :)

Just don't mess with things you aren't sure about, not everything from the unlocked menus works, I don't have a Y500 to test it myself so I can't tell you.

Question... If I'm using a y400/500 with the 650m and bios v2.02, would I be able to upgrade to 2.03 or 2.04 (since I believe those include 750m BIOS, not 650m)?

Why would you want to flash to a newer BIOS? Does it have something new that's worth upgrading? Has anyone tried the Killer Wireless N-1202 on their Y400/Y500? Thought it should work since it has 2 antennnas and the same bluetooth version.

also, is it normal for my GPU to have a voltage of 0.925v on both cards? and why does [MODIFIED] show up in the bios number in nvidia inspector?

here is the snapshots

I wouldn't waste you time and $ on the N-1202, get the AC-7260, it cheaper and is on the latest wireless tech. The N-1202 are descent but the price tag I'm not a fan of. (At least here in canada their pricey)

The N-1202 costs like 47.99 on Amazon and the AC-7260 is about the same price (eBay at least) but I'm not so sure if it'll work well since it's kinda "new" in the market (and it'll probably have driver related issues), what I want to know if it'll be better than the N-1202, I mostly game on this notebook so if the AC-7260 performs better than the N-1202 I'll probably upgrade to it :) .

      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!
