Hello! I updated the bios with

"modified whitelist BIOS V2.07 - 5DCN40WW removed WWAN /WLAN whitelist check"

Now the Wifi card is dual band intel 7265AC with bluetooth on it.
But here is the problem, after every restart or shutdown I have first problem with a usb-  the external mouse stop working and after every second restart or shut down I have a BSOD with "bugcode_usb driver" error in dump file.
For now I try diferent drivers, for integrated broadcom and for intel card separately but integrated card every time have 4 pheripheral devices without driver and not work properly, I found а working driver for bluetooth in the intel card 7265 but the problem with BSOD exists.
No matter if I disabled every bluetooth card in device management or separately and restart I have a BSOD on the end.

Do you know if there is an option to turn off the built-in Bluetooth through the BIOS? This will be very useful. 
Thanks!

So, that is, I need 5 post plus 1 week to get the promotion? And then should have the right to download?

Hi, i am owner of a Lenovo Y480 which is using GT640M LE, does it under this category?

I flashed a modded firmware and it has bricked.

I found there is EN25Q32B and EN25QH16 bin files, BUT descriptions are LA-8001P N13P-GTm while 640M LE was N13P-LP.

Does it fit and rescue my laptop?

Howdy all! 
 

I would like to thank all the people, in particular @svl7, that has contributed to this achievement of unlocking this Lenovo's BIOS, I have read all the 65 pages to better understand how to do it and what are the principal problems encountered. 
 

Since last week or so, I'm trying to BIOSFix my original BIOS to unlock it since the Wifi card died in my Y580 laptop, but there is a thing I can't understand and I can't put my finger on it. 

I know it's an old thread revival, but if someone can help me understand what I'm missing, it would be really appreciated. 

I have a Lenovo IdeaPad Y580 (2099) Windows 7 premium
InsydeH20 Rev. 3.7
BIOS Version : 5DCN40WW (V2.07)
EC Version : 5DEC40WW (V2.07) 
CPU : i7-3630QM 
 

I can successfully extract the BIOS with the FPT tool. I rename the original BIOS under the name : biosy580.bin, it's a 4.50 MB file. 
I'm trying to use the QIWY3207.rom (included in the Y580 - Y480 'unlocked BIOS' v2.07 folder) for modifying my original BIOS with the BIOSFix tool. 
Unfortunately I don't have any success, the QIWY3207.rom is 6.12 MB in size and both BIOS should be equivalent in size, well usually it's the way it works, I could be wrong, but according by the error I'm receiving in BIOSFix :  ERROR : Modified BIOS file is invalid. Press enter to exit.

I did a test with the modified BIOS v801.rom included in another file named Lenovo Y580 - Y480 BIOS v8.01 (5DCN90WW) - Mod  since this BIOS is the same size 4.50 MB as my original BIOS. With that one BIOSFix is able to modify and gives me a new BIOS named v801FIX.rom 

I'm really uncomfortable to flash my laptop with that version since it's not the same base version v.2.07 -> v8.01

I compared both my original BIOS (biosy580.bin - 4.50 MB) VS. modified (QIWY3201.rom - 6.12 MB) with an Hex tool and both looks compatible, except for the size. 

What am I missing?  If someone can enlighten me please, that would be very appreciated.

Hi! 

You can upload your file bios backup into any fileserver and post the download link. Or you can send me your file backup of bios via PM.  To create backup of bios use attached utility. Extract attached archive directly on the Desktop and run Backup Utility as Administrator (right click mouse, choice "Run as Administrator"). Utility will create archive "results" directly on the Desktop. Post here this archive "results" or upload your file bios backup into any fileserver and post the link.

Thanks for your fast reply, it's much appreciated. 

The file created by Backup Tool is in your private box. Here is the link for the original BIOS dumped with FPT in DOS mode.

Ok. Your bios with unlocked Wi-Fi whitelist done. Check PM.

[Soul Harvester]

I big thanks to @Klem, he helped me tremendously. I've just installed a wireless Intel AC7265 card in the laptop and it's working flawlessly! 

Again, thanks to everyone, you're all superheroes !

Anyone still have this model Y580? I just accidentally messed up the video configuration in the bios and change the SG into external gpu. After restarting it has no display but it boots up to windows since I can hear the start up sound, can hear opening the stickynotes by pressing the shift key multiple times, and can shut it down by doing alt+f4.

 

I also tried to blind bios reset which includes pressing the arrow keys left(x1), down(4x), and enter(4x) but still no luck.

 

I also tried using an external monitor via hdmi and vga but with no luck as well.

 

I also tried removing the cmos batt but since it is soldered I only tried to removed it from the clipping to its motherboard but no luck as well.

 

Mine has an unlock bios. Anyone out there can video their bios from top to end to change the video configuration back to SG?

 

Thank you so much!

Hi!

1. Completely disable (turn off) laptop with long press and hold the Power button.

2. Press and hold F2 button, and start laptop (to go in bios setup menu).

3. Press F9 button, then Enter button. Then press F10 button, then Enter button.

Thanks for the response. I have tried this to load the default while blinded in the bios but it just restarted, goes to boot up windows (start up sound) still no luck with the display.

 

 

I hope someone is still around with the same bios. A video of changing it back from PEG to IGFX might solve this.
