Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

I have a question..

I've got a Y500 with gt650m sli and now the 2.00 stock bios.

I want to flash the both gt650m cards to overclock it. (integrated and the ultrabay one)

The instruction is saying "Flashing the ultra bay 650m - only for SLI users with BIOS v2.02" and

"The modified BIOS v2.02 also contains a vbios"

What shall I do now? I can't see a 2.02 custom BIOS under "Attached Files". Or should I flash the 2.04 BIOS and after that the OC ROM for the both GT650m with the nvflash-tool?

Or needn't I flash the gpu bios after flashing the custom 2.04?

Sorry for my bad english and please help me. :)

Flash the 2.04 modded BIOS. That will add the VBIOS for the integrated card. You have to download the modded VBIOS and flash the ultrabay card separately. Once you do that you can OC both cards.

Hello everyone how much the temperature increases after the overclock? Cooling Pad is required?

Flashed the 2.02 BIOS update, the update ran and installed just fine, BUT, then my screen went black... Let it sit for about an hour, decided to shut it down manually, started it, black screen, no beeps, no nothing...

After about 10 hours of googling, trying different bios recovery things (none worked btw) and dragging my hair out, I decided to open up the laptop to see if I could find the CMOS battery (long shot, I know), couldn't find it, saw the RAM sticks and figured I'd give it a go, removed one of the sticks and then tried to start the laptop again.

It started without a single problem <.<

Perfect timing to have a RAM stick die on me!

Anyways, will buy some new RAM shortly and then proceed with the modding to 2.04!

Quick little question though, haven't seen anything about it, is CPU undervolting possible with this mod?

If I'm stuck at the boot loop should I just try to flash a different bios and see if it works? Any help would be greatly appreciated. Really not sure what to do at this point. Tried system restore with no luck and system repair, etc.

Question I would like to ask is do you do it he same way as flashing the bios also using the same dos commands to flash the ultra bay? of course the difference being the .rom file name Thank You Again in advance

Use the nvidia flasher, load it on the drive, boot in to usb, and BAM go to the rom and overclock the other pci device.

Hi,

I have a gap between the touchpad and laptop. I want to sent my laptop for warranty. It's very annoying.....

I have the hacked bios installed. Also I have the Original backup of my bios firmware. How do I flash the Original firmware restore back?

Thanks

Follow the same instructions in the OP that you used to flash the modded BIOS. Make a DOS-bootable USB drive, put your BIOS backup and other required files on it, boot from it, and flash the BIOS backup file using the command.

Thank you very much! I will flash the backup firmware tomorrow. Also without modifying the backup firmware as the windows 8 serial number is already correct, right?

Have a Y500 with 1.05 bios. If update to 2.02 goes wrong can you restore to 1.05?

Back up your BIOS for sure. There is a tut in this to do it. I don't use the exact tools they do here but the files I do. All about user preference.

I had a y500 with 1.05 bios. I've updated to 2.02 through insydeflash and got ethernet problems.

Then I've flashed it with svl's mod (2.04) and it seems ok now.

I had issues with getting gigabit link (it would always go to 100Mb) until I upgraded to the latest drivers for the wired NIC. I'd recommend that as a next course of action if the problem returns or you have any other weirdness.

Hi All, can anyone help me with this issue I got......

I got the Y500 with SLI and I just updated to Windows 8.1 and now 1 of my NVidia 650m in device manager says "Windows has stopped this device because it has reported problems. (Code 43)", I tried to look up on the web and read that I must update my bios to resolve this problem. Lenovo doesn't have any bios update on their support page.... I'm currently running Bios Version 2.00 will updating to 2.04 fix the problem?

Thanks

I've got the same problem with the 2.04 and modded VBIOS in the second card. Not sure exactly who needs to update what, but my understanding is that Lenovo ultimately has to release a new BIOS to deal with the problem. Alternatively, you can revert back to some (very old) drivers Lenovo has posted on their site under the 8.1 support - it's something like driver 307.xx -if you're not running many recent games. That'll bring the SLI back in the interim.

      Hi everyone, I have a problem. I need to unlock the bios settings because I only have basic functions and I need to increase the memory of VRam. Sorry if I posted a post not in this topic.

      In this thread you can post your requests for Lenovo ThinkPad X240.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden advanced menus and settings in bios setup menu, or upgrade to new display (with brightness control), then you can post your request in this thread.
      Important!
      For creating your personal bios dump and to flash your bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!
       
      Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.

      Hi,
      I am looking to remove the bios wifi whitelist restriction for a Lenovo G700 version 7ACN89WW . This is version 3.07
      I have used a programmer to read direclly from bios chip but it has failed. Is there any other method available to remove bios restriction from this laptop?

      Hello to all big format laptop users!
      I`ll try to make it as short as possible. I have the Alienware M18X R1 for about 7years, i think. It was a problematic machine all the time. But during warranty period local support fixed everything super fast and free of charge :). I even upgraded from gtx 580m sli to gtc 780m sli. And made primary hdd samsung evo ssd. Unlocked Bios. Power brick i changed 3 times by now. Battery once. And 6moths ago one of the long time ago installed 780m died ( started with artifacts on screen then refused to boot windows). Replaced that and was as happy as ever. The machine kept working stable and i pushed all i could get from it in reasonably modern titles. Even tried RDR2 on default settings, gave me 17fps :). Not sure if SLI is supported for that game. The point is it was running fine for last 6 months.
      What happened:  Gaming as usual, room temp 23C. After around 2hr suddenly black screen. The laptop switched off by itself.
      What i check: First checked power brick. Green light off. Unplug from wall and laptop. After plugging in wall green light back on. Connect laptop light off.
      Next: Tried take out battery, unplug. And hold the PWR button for 1 min. Try to start on battery - nothing. Plug in - green light off again.
      Later: after some googling found that need to try to remove video cards. Done that. OK Nice! Plug in power and it starts as nothing happened on the integrated intel video.
      Found out that i one of the video cards is plugged in that triggers the power brick to trip. (the original upgrade 780m from years ago). 
      Start with GPU: Insert the other one in its slot. Systems start. But immediately i notice there`s no video drivers. OK i think reinstalling and job done. Drivers reinstalled, asked for restart. After restart nothing. Still no driver.
      Windows device manager: This is bogging me. it shows that i have 670M instead of 780m. Windows gives Code 43 Error.
      BIOS: I go into bios just to find that that it has reverted back to A05 (hows that possible?). And its so limited that i cant even choose witch video card to use. But it detects nVidia GFX.
      How to get at least my single 780M to be working?! Update bios again to unlocked? Did this event fry Vbios on my other card maybe?
      System: m18x R1
      SLI gtx 780m
      Unlocked bios (before event)
      nvidia driver 443.x(or there about)
      Win: 7, 64bit
