Here to confirm the BIOS Recovery methods above works.

First of download the BIOS from here (change the .txt to .exe from the readme links).

Next extract the .rom file from the downloaded .exe using 7zip.

As BDMaster's post says, you need to have multiple files with different extensions.

ZIVY2.wph
ZIVY2.bin
ZIVY2.ROM
ZIVY2.FD
ZIVY2.BI
WinZIVY2X64.wph
WinZIVY2X64.fd
WinZIVY2X64.rom <- .rom extracted from the .exe file
WinZIVY2X64.bin
WinZIVY2X64.bi


Format a USB drive with FAT32(default) and paste the files in it.

Unplug AC cord.

Open up your laptop back cover, unplug the battery connector and CMOS battery connector.

Close the back cover, press the power button for 20-30seconds.

Connect the pendrive.

Hold fn+B and then connect the AC cord.The power light should glow red.

Press the power button and leave then leave the fn+B.

The laptop turns on with fan speed on full, it starts to beep and stops when the flashing is done.

Now the BIOS screen should pop up, configure your settings and restart.

Note: The laptop beeps for 5-6minutes and restarts on its own, so do not pull the plug.

Hi guys. the same situation happened. I flashed a modified BIOS through a slip mod. Everything was OK.
But today I decided to make an undervolt through the BIOS.
And after that the black screen.
Lenovo y50-70 UHD. BIOS- 9ECN37WW(V2.01).

Tried versions of the rom file from: zivy2113, 9ecn31ww, 9ecn37ww, 9ecn40ww
Disconnected the battery, the CMOS battery, the AC power, pulled out one memory bar.
I did everything according to the flashing procedure.
But when starting in recovery mode, the fans spin at full speed, but there is NO sound.
What can i do wrong?


Is there an option to directly flash the SPI flash? Through 341A programmer.

I read the SPI flash (model MX25L6473E). made a backup.
But when trying to write WinZIVY2X64.rom from zivy2113, the program (AsProgrammer_1.4.0) swears that the size is larger than the volume of the SPI flash.


Added BIOS backup, which I did thouth Universal BIOS Backup ToolKit 2.0, before modifying/unlock the BIOS.

Hello everyone.
I solved my problem only by flashing it directly into the SPI flash. Via the 341A programmer and a Test-clip.

Found a BIOS that fits my MB ZIVY2 LA-B111P REV-1.0A.
BIOS version 1.13.
And after the flashing, the motherboard immediately started without problems.

Updated to 3.03, modified BIOS, lowered the version to 1.14 and updated to the modified 3.03.


BIOS version 1.13 for Motherboard ZIVY2 LA-B111P REV-1.0A. in attachment.
I want to put it here, maybe it will save someone a couple of hours of life in search of a working image for the SPI flash.

Format a USB drive with fat32.

Disconect the adapter.
Turn off the laptop.
Put the USB on the left side.
Hold FN B -> Plug the AC ==> Press the power button.
Hold the FN b for a few seconds.
Release the FN b nothing is happens.

The fan is working and I'm having a black screen.

I have connect this laptop to a HDMI cable monitor same issue.

Hi friend, the Firmware is All Regions packed, but the Bios is only a Region of it so to Recovery your bios you have to use the Bios from
original Stock Bios File or extract from Firmware the Bios Region only by UEFI Tool ...
Look here to recovery bios procedure and file :

Or extract it from the Firmware file attached above, open it by UEFI Tool and select the Bios Region then by the right mouse click save it and use :
