Lenovo Y50-70 unlocked BIOS menu / wlan whitelist mod / vbios mod

Dear Friends,

 

I am a owner of Lenovo Y50-70 for 7 years. Laptop has been great machine all the way. An abouth month ago I managed to spill a water on it. I immediately turned it off, and disassamble it (which I have done multiple times during those years due to cleaning or upgrades of RAM and SSD). To my max surprise, laptop works great. 
Just wifi-card seems to have issues - random freeze of connection and then drop of connection in random times. Sometimes it works fine all day, sometimes I have to perform manual  device disable / enable procedure. So I think, this card is not OK, bought new (well, not new), same Intel 7260NGW and run in to whitelist issue (maybe diff HW revisions?). 
This led me to look for more answers so I ended up here (currently have ordered new Lenovo Legion 5 Pro, but this Y50-70 still works great tho)

 

Lenovo Y50-70 uses currently most recent BIOS 9ECN43WW.

 

So my Q is:

Can you please provide me unlocked BIOS without whitelist blockage + additional stuff might me great, I def wont get rid of this machine, it deserves to stay (runs W11Pro!)

 

Below is attached my BIOS dump did by "Universal BIOS backup tool kit" since "BackupTools.rar did not work"

Thank You very much!

 

P.S

Found here all BIOS versions to download

Hello Klem!

 

My Y70-70 is all of the sudden only showing black screen with backlight on.
I wonder if you can modify the bios to only use the internal graphics (UMA) and completely disable the external GPU?

 

I want to verify if the pc still works only running from the UMA.

 

Thank you.

Hi!

Try to use BIOS recovery procedure:

Take a USB flash drive, go to "My computer" Right click on the USB drive and select Format. Change the filesystem from NTFS to FAT32. Format the drive.
The flash drive does not need to be a 'bootable' flash drive. Leave it as is.

1. Download archive ZIVY2.rar from this link:  https://files.fm/u/tzhj7h49k

2. Extract archive ZIVY2.rar and copy the file ZIVY2.bin to the USB flash drive (format FAT32).

3. Unplug your laptop from the AC adapter.
4. Disconnect the battery from the motherboard. 
With everything disconnected hold the power button for 20-30 seconds. This purges residual power from the board.
Disconnect the hard drive (This ensures that the USB flash drive is read first. I'm not sure if this is necessary, but it may be need).
5. Plug in your USB flash drive into any USB port.
6. Press and hold Fn+R buttons together.
7. While HOLDING Fn+R, plug in the AC adapter.
8. While still HOLDING Fn+R press the Power Button.

9. You should hear the fans turn on very loudly, no display, and no keyboard lights.
Let go of Fn+R after a few seconds
You should hear a rather loud series of beeps. This is the BIOS being flashed. Let it beep repeatedly as long as it needs to. When the process is done, the beeping will stop, and the laptop will turn itself off. It may also reboot.
If all went well, you're screen should now be working just fine.

 

If it doesn't work, then try to use Fn+B combination instead Fn+R.

If it doesn't work, then try to use another USB flash drive (USB2.0, not USB3.0), also try to use USB with smallest size, for example 2-4 GB.

Also, try to use another USB port in laptop.

 

If it doesn't help, try to connect external monitor.

Wow! Thank you for this thorough guide!

I'll try it immediately.

 

If it still doesn't work, would disabling the external GPU still be a possibility?

 

Thank you again :)
