Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

Hello everybody,

So I have bought an Intel Dual Band Wireless-AC 7260 and put it into my Lenovo Y500. When I wanted to boot my laptop it said 'Unauthorized network card is plugged in. Please remove and restart.'

So I checked the internet for some answers and I found out that there is a whitelist for the Lenovo Y500, and possibly for more Lenovo models. I also read that you can 'unlock' your BIOS to make other network cards work. And that's when I came across this topic.

At first I made a bootable USB device without any problems. After that I wanted to make a backup with the

FPT_DOS zip file, I got an error message when I executed the file named 'fptw64' I need to press any key, and after that again. After I pressed the second key the windows will just disappear and I won't get any file. After that I tried using the file called 'fpt' but I could not execute it because I got this: 'This app can't run on your PC. To find a version for your PC, check with the software publisher.'

I figured I would make a backup of my BIOS with the 'universal bios backup toolkit 2.0' and it worked. I put that file into the BiosFixer and I got a file. I put that file, along with the prr2, fpt and fparts.txt file on the boot USB and tried flashing it. When I did that I got this message: 'Error 28: Protected Range Registers are currently set by BIOS, preventing flash acces. Please contact the target system BIOS vendor for an option to disable Protected Range Registers.

But what do I do now?

Thanks in advance.

I allready have the 2.04 bios but want to get rid of the Whitelist, because of a new intel AC7260 card which I am willing to install.

If I follow the tutorial (prefering the Vimeo video) can I install all wifi cards with it?

So is the whitelist the reason I can't update the stock 2230 drivers? I'm thinking of unlocking 2.04 and purchasing this card if so. I'm on 8.1 and when I try to install the 2230 latest update the y500 bluescreens.

My pc got really slow after doing the bios flash. Starting up goes slow and in windows itself there seems to be a lag of 4-5 seconds with the click itself.

After watching a video of the mod on vimeo I saw a difference in size at the FPARTS.TXT wich is 274kb at the video and mine is 8kb.

I couldn't find the PRR file but I did use the PRR2 file, is this a new PRR(1)?

Did I use the wrong FPARTS file?

Lenovo seems to like locking their stuff... so thats a likely outcome.

What laptop do you have and which mod are you trying to use? This mod is for the Y500/Y400 which is an older model. Mod for the Y510p/Y410p is in this thread: http://forum.techinferno.com/lenovo-ibm/4668-lenovo-y410p-y510p-unlocked-bios-wlan-whitelist-mod-vbios-mod.html

Newbie here, so bear with me... Apologies in advance for the long post, just want to be thorough...

After having some issues with my y400 recently, I performed a full system recovery. I ran and installed all relevant Windows updates, which included the upgrade to Windows 8.1. I also checked Lenovo support for all driver updates that applied. Here is where I run into a problem. It seems that I have the most recent BIOS update (v2.04), but not the most recent VBIOS (NVIDIA GeForce GT650M Second VGA BIOS Update for Windows 8.1 (64-bit) - IdeaPad Y400, Y500). That said, when I try to install the new VBIOS, it doesn't take. A command window opens briefly and immediately closes, not allowing me to enter any commands, as the Lenovo instructions would have me do.... Then nothing happens. I've tried doing this numerous times with no success. I should also note that I keep getting pop up notifications in my task bar telling me Windows has disabled my GT650m, and/or "display driver has stopped responding and has recovered"... I'm at a loss. Any help or advice on this would be greatly appreciated. Here some additional info that may be relevant:

Device Manager showing only one display adapter- Intel HD Graphics 4000 missing:

Thank you for reading through all of this... and feel free to ask for any addtonal info....

This has been my problem with my Y500. You can see my thread that I started on this , but I dont mind if we can find the solution here. For me my Ultrabay 650M works with the unlocked vbios but eventually stop responding as it is with JuneBug. I am wondering if it is a bug in the bios?

Y400/Y500 technically doesn't support internal graphics of the CPU.You can to turn on it in BIOS and you'll be noticed in AIDA64 about intel hd 4000 showing but in fact it doesn't work at all

This has been asked a million times already. ​iGPU is impossible to access.

No no idea about Hackintosh.

I own a y500 with g750m

have you tried starting fresh with fresh install then updating BIOS/drivers with lenovo website listed. Then applng svl7s mod? If you vBIOS keeps getting curropt. I had to send my laptop into lenovo for a new one because the mobo has a issue in its reg to wake the laptop when you close the laptop. Espically if your running 2mobo unlocked, it sounds like you have some curroption in .net runtime loaders. Even if your not OC the ultrabay or onboard. try using the tools on this site to help find solution for fix. Wagnard Tools

I know most of the errors come from the powerspecs required to the mainboard. make sure your powercord/battery are g2g when applying fixes. Flashing vBIOS over and over is only going to cause sys reg errors and problems. I recommend starting with fresh load, updating authenictic signed drivers, applying the new BIOS patch, then flashing the mod's for stability.

Kind of hard to help you out without more detail on the exact error your getting when it happening, and when it started to happen. Also did you purchase a 650gt ultra bay and have a 750gt onboard or do you have the older y500 version with the gt650 onboard. please list more specs, and errors : )

      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.
