[REQUEST] Lenovo Z51-70 (C2CNxxWW) BIOS Unlock

[Dudu2002]

I have this same laptop model. I need to replace the wireless card to one which is blacklisted.

There is any way of making the new wireless card work apart of SPI-programmer+SOIC8 chip?

Thanks.

Hi
for flash mod you need SPI-programmer+SOIC8 clip!

Ok, I'm glad that it's working!
Here's the file with 64MB DVMT: https://drive.google.com/file/d/0B4NHIBM...hDM0k/view

Hi,mclarke2355

I want to asked can I enable Mini PCIe hot plug by uising administrative command prompt? 
Because i cant access advanced bios menu to do that.I pluugged a egpu at wifi PCIe slot

I have lenovo z51-70
I wanted to get egpu through the m.2 port which is used for WiFi card it's m.2 key a/e aka ngff

The problem is after research I found that the bios have whitelist problems (I didn't get the gdc or GPU yet) so I wanted to make sure it's unlocked before getting anything

Found some posts about lenovo z51-70 not be able to modified but I think that everything can be modified so I wanna know everything and what I need to search about also what to dumb here for better knowledge and what do I need to modify
....etc

Everything

Everything can be hacked

Note: talking to lenovo's support said that there's no advanced menu but I have to modify the bios to get the job done.

Hi
Your bios is rewrite protected
Bios mod can be flashed using SPI-programmer+SOIC8 clip only

is there any soldering - de-soldering process?

what other benefits i can get modding my bios other than white-listing? 

is there any risk to brick my laptop?

thought i will have to order that programmer and clips from outside my country but found it on some stores so i think i wanna try doing it

Hi mate,
Look into this EFI IFR file and find the Variable to modify :

http://rghost.net/private/8vKznLLgX/9cdc...6d1e90b771

Then Look into FalseClock method :

Let me know

See the disabled if case at the end?

Code:

Disable If: {1E 82}
0x51D25 Variable 0x2A1 equals 0x0 {12 06 A1 02 00 00}
0x51D2B Ref: Serial IO Configuration, Variable: 0xFFFF {0F 0F 18 07 19 07 0C 00 00 00 FF FF 00 00 37}

0x51D49 End If {29 02}

So I basically have to change 0x2A1 to 0x1? But my BIOS area is write protected according to Backup_tools12.
How else can I do this?
UPDATE: Using the efi shell from falseclock's method, the shell never boots from usb, stuck at black screen, so I tried with grub uefi shell, and doing
setup_var 0x2A1 0x01 gives me
offset 0x2A1 is: 0x00
Setting offset 0x2a1 to 0x01
error: can't set variable using efi (error: 0x000000000000001a)

Any idea?

So I'm looking at modifying this 0x2A1 variable using the H2OUVE.exe method since that works for me.

I was wondering if I would just then change from

000002A0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 

to

000002A0: 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00

See my output below:

Am I approaching this correctly? Will this possibly enable the advanced menu in the bios?
I'm just trying to see if this works.
My next goal would be to remove the wlan whitelist using this method, but I don't know yet where to find it, even when looking at the Z51-70 EFI table that was provided in this thread.

Thanks all.
