[REQUEST] Lenovo Z70-80 (ABCNxxWW) BIOS Unlock

[David-B]

I just purchased a Lenovo Z70, and I am disappointed to find out that it uses the well-known Insyde H20 BIOS which restricts access to certain settings unless it is modded. I would like to access the restricted BIOS settings, but I do not know how to do it myself. I would appreciate it if someone would do it for me, but at the same time, I would also like an explanation on how it is done so that in the future, I may be able to do it myself.

Here is the download for installing the latest version of Insyde H20 on my laptop: http://support.lenovo.com/us/en/products...s/DS102563

From looking at other posts on the forum, it seems that everyone is posting a "recovery.rar" file that is generated using this utility, so here is a copy of one generated from my run of it: http://rgho.st/6YVnVqjYv

If any additional information is required to assist me, please let me know. I will be glad to provide it.

Anyone? Please?

Even if you cannot mod it for me, could someone explain how to mod it so that I may try it myself?

Hello!
Your bios chip is rewrite protected!All newest laptops have this protection.
So you can flash mod using SPI Programmer+Pomona SOIC8 Clip only!
If you have/buy this toools now we can continue!
Let me know!

That is unfortunate. Thank you for the answer though.

Hi. I have 1.5 years old Lenovo z70-80 (80FG008BPB) and i'm looking for BIOS with unlocked advanced options. My current BIOS is ABCN73WW. I want only to change the time when processor fan is turning on (now it turns on eveytime when processor usage reach 30% even if it's temperature is low, like 32 deg Celsius. It's really annoying.). Could you help me? Sorry for my english, thanks and have a nice day

Hi everyone, I apply someone who could help me.

I got a Lenovo Z70-80 and I want to unlock hidden options or pages with advanced configurations in my InsydeH20 BIOS because I want to install Mac OSX correctly. Well I can install it but the video performance is poor.

I want to modify the shared memory to integrated video but my BIOS doesn't show that options.

I found this site with instructions

https://patrikesn.wordpress.com/2015/01/...comment-54

and another similar video to my case https://www.youtube.com/watch?v=kDLTEZrRqsg&t=3s

I tried both but I have write restrictions to save changes


This was my process


1. Booted with Linux Mint 18.1 or Linux Ubuntu 16.04.1 and I connected to internet by network lan and before of this I retired my    

    wifi physical card and I disabled it in BIOS. (Inside both linux I was like root user).


2. After I installed ghex software to follow the guide on net for both cases of linux and open the file with the name

    Setup-a04a27f4-df00-4d42-b552-39511302113d and modify it the line 

    00000210 to 00 00 00 00 00 00 00 00 00 00 00 01 01 00 00 00 and continue to save it.

3. In that moment was when I had the message of restriction to save.

Serg008 from forums.mydigitallife.info told me that my bios is rewrite protected for unauthorized bios images, and to modify it can be flashed using USB SPI Programmer like you know use it, is for that reason that I apply for help here.

This is the original lenovo download file BIOS in case you could modify it to reflash it after.

Now, I'm resigned about the write restrictions in my BIOS. And I have thinked to buy a SPI programer and I want to know what's the best cheaper device. Someone told me about this MiniPRO USB Universal Programmer TL866CS and I want to know if is for my case.

By the way, I think the chip in my BIOS is Winbond 25064FVSIG. I have attached pictures for more details.

I'll wait some answer.

Thanks in advanced.
