Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

Sorry bud, I honestly have no idea and I'm not using Windows 8 anymore. Don't think I'll be of any help. :(

If the BIOS flash wasn't successful, the system wouldn't even boot with an aftermarket wireless card installed.

I appreciate the reply. This is just irritating. I'm offering at least a $30 donation (enough to buy a good bottle of maker's mark ;) ) to anyone that can provide a working solution to the problem I'm having.

Does the WLAN card work in other machines? Have you tried using Driver Sweeper/Fusion to clean out the old wireless driver? Do a system image backup and reinstall the OS as a last resort? This way you can go back if reformat doesn't fix it.

I dun have the card, so this might not help much. But I read somewhere that Lenovo power management app can cause trouble, try uninstall it. If all method fails, do a backup and recover a clean os to know whether the problem is with the card. If you suspect it's the bios issue, revert to original bios and update to official 2.04 b4 modifying it. Hope it help

@svl7 I have mod my Y400 with your bios mod, Thousand Thanks! :chuncky:

btw, i have tried many configuration on bios, and i tried to enable Intel HD Graphic, I was able to startup without any boot problem, ONLY by set to " PCI " as primary display.

but, when windows done startup, i noticed that GT750M is not enable, and i was able to install Intel HD Driver. i think i'm running on Intel HD Graphic, but, with no driver, so, its a bit stuttering..

Here's some pic

Hi, I'm new here and I signed up because I was planning to switch out my stock wireless adapter to the 7260. I see your signature (or is that what it's called?) contains the Intel AC 7260 but through this thread, no post confirmed that you succeeded with the installation. How did you go through with it?

Is it an either or thing if you enable the intel graphics? or can you enable it for power savings on battery?

You cannot enable it, period.

I will try these both to see if they work. If so, you'll def be hearing from me and I'll buy you both each a few or more beers :) Give me a few days as I have drill this weekend, so I'll be packing, working, and getting ready for it.

Yeah, try what jamescc suggested. Flash the backup of your original BIOS, update to official 2.04 using this, and then mod it again. This'll put both BIOS and EC version at 2.04 as right now you have BIOS on 2.04 and EC on 2.02. Not sure if it'll make any difference but it's worth a shot.

Has anyone done this on a purely Linux system? I can make the USB and the customized BIOS on a Windows desktop, but I haven't seen much on grabbing the backup of the BIOS on Linux. I'm looking at flashrom now, but I'd appreciate any other advice/tips.

sorry, but just need a quick answer.

my current y500 is already running on bios 2.04. so its safe for me to just flash the modded bios using the normal method stated in page 1 right?

      A part of my BIOS got corrupted that controls my laptops backlights. Other methods like the Gary Key fix did not work for me because I do not get any light up during post. i followed this guide  that says I need to extract and use the 6MB portion of an 8MB bios dump, only AFUWIN tells me "Error, ROM file size does not match existing BIOS size which is because my laptop BIOS size is only 5.87MB.  I don't need to flash the whole BIOS, I only need to flash a portion of it. 
       
      I've searched everywhere online for a dump of my laptop model but non exist that I know of.

      I fiddled around with modding my laptops BIOS to unlock XMP profiles and hopefully seeing if optimus could be disabled. After flashing my modded bios and trying it out, I noticed that my keyboards backlight no longer turns on. I was unaware it requires an official BIOS to function. They backlights wont turn on unless ASUS ATK package is installed but now it seems it also needs an official BIOS?
       
      The modded ROM and tool I used if anyone has any experience with this and doesn't mind telling me what to enable/disable, or anything else i can do to re-enable them

      Hello !
      I tried a tutorial on the forum to remove the supervisor password on a X260 thinkpad but the winbond 25Q128FVPQ chip is not recognized with the programmer CH341A and ASprogramer (does not detect automatically and not manually). Plugged into the motherboard with a soic8.

      Can you help me with detection?
      Can I find the password with the software or do I have to write it?
       
      Thank you so much !!!

      In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
      Important!
      For creating bios backup and to flash 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.
