Bios Mods -The Best BIOS Update and Modification Source

I will give it a try today when I get home from work. Donation is on its way now!

Hi all

New to the forum. I have read through this thread, so have a basic understanding of what is required.

I downloaded the tools from links provided, however, only one of them would run.

I have uploaded the results from that one here: https://www.sendspace.com/file/178t56


I noticed in some of the files in that .rar that there were SPI lock errors, so one assumes I need to go down a programmer route.

1) Which programmer do I need / how do I determine which one I need

2) I would like to remove the whitelist and throw in the hidden menu options - will the above file allow someone to provide me with a modified bios, or can I be provided with the required changes to be made to try myself?

3) Do I need to downgrade my bios before flashing new bios to it?

Thanks
John

Ok friend,
The best thing is to get the Tools to get free (SPI Programmer + Clip) but
We can try before this trick :

0x21067    Setting: LPSS SPI Support, Variable: 0x163
0x2108D     Option: Disabled, Value: 0x0
0x210A9     Option: Enabled, Value: 0x1
0x210C5    End of Options

0x2179D Setting: BIOS Read/Write Protection, Variable: 0x1FC
0x217C3 Option: Enabled, Value: 0x1
0x217DF Option: Disabled, Value: 0x0 (default)
0x217FB End of Options

0x21A25     Setting: TXE HMRFPO , Variable: 0x170
0x21A4B      Option: Disabled, Value: 0x0 (default)
0x21A67      Option: Enabled, Value: 0x1
0x21A83     End of Options

Into EFI IFR, I found this Variable to Lock and Unlock Bios so We can try modifying his value
by Falseclock Method and see the effects !
Look here about FalseClock Method :

https://www.bios-mods.com/forum/Thread-R...-EFI-shell

So this Method use an modified EFI Module (cracked) to write into the VarStore Variables !

Look here for Video Guide :

Then You have to prepare an USB Stick Fat32 Formatted and create EFI
Structure into so create directory structure USB_Unit:\EFI\Boot
copy into the EFI Module cracked BOOTX64.EFI You can download from here :

http://www.mediafire.com/download.php?81vegw2aw0pxcib

and last to do is make some settings into Bios Setup Menu :

Legacy Support: Disable
Secure Boot: Disable

Then Boot from your USB Stick into UEFI and execute this command :

setup_var 0x163 0x01

setup_var 0x1FC 0x00

setup_var 0x170 0x01

Then rebbot your Laptop and redo again the result file !
Let me know
Regards

P.S. It would make the Eeprom Chip Unlocked

Soo..... I have tried this, not sure where I am going wrong, but when booting from the usb it just stays on a black screen

I do not have a enable / disable legacy mode. All I have is a greyed out Boot mode: UEFI

Is there anything else that needs to go on the usb stick apart from the bootx64.efi file? (obviously in the efi/boot structure)

Tried the novo button last night as well.


I don't really understand it, as it will boot from a non cracked bootx64.efi file

Problem is Secure Boot (It check RSA signature) It locks boot !

Haven't seen video ?

You will have this settings into Bios Menu Boot Tab :

Boot UEFI and You have to set to Legacy Support (Secure Boot Disabled)
Boot Priority and You have to set to UEFI First (Legacy USB whit UEFI)
USB Boot and You have to set to Enabled (Boot from USB)

Already have secure boot disabled, but boot mode remains greyed out.

It will boot from usb, just not with the modified bootx64 file.

What SPI Programmer / clip do I need to buy?

Thanks

Yes You can buy the CH314A + Clip . . . 
This is your Eeprom Chip :

    --- Flash Devices Found ---
    GD25LQ64    ID:0xC86017    Size: 8192KB (65536Kb)

Look here :

https://www.bios-mods.com/forum/Thread-R...5#pid74575

Let me know

P.S. I would make some tests to help many users not lucked !

Many times It needs to create a SVP = SuperVisor Paddword to Enable that option !
Have You tried ?

Yer, I have the password set. I have messed about with every possible combination now and no luck. Reading on another forum the yoga 2 11 now only supports UEFI now, following bios upgrades.

Is there anyway to get into the EFI shell with another boot file?
