[REQUEST] Lenovo Thinkpad X230 Tablet (GCETxxWW) Whitelist Removal

[Dudu2002]

Hi guys I'm relatively new to the bios modding scene, but I want to use a broadcom bios so I can make a hackintosh in this pc. I ordered a pomona chip and have wires/raspberry pi, so I was just wondering, how do I get started? Apparently I need to contact someone called Oleh, but I don't know how to pm. I know there's information needed about my system, but I don't really know how to give you that. A small helping hand would be greatly appreciated. Happy hacking!

Hi everyone!

I've been downloading modified BIOS's from the forum for a few years now and I would like to learn how to mod my own BIOS's. I have a Lenovo Thinkpad X230t the I would liKe to do the following mods to:

1. Whitelist removal. - This part seems easy enough as there are plenty of examples on the forum
2. Unlock advanced BIOS menus.
3. Disable genuine battery check. - I just had to pay $90.00 USD for a new battery for one of my X230's, (I have two, plus 2 X220t's, X201, X61t and a T60. What can I say, I like Thinkpads!).

Any suggestions.advice on how to proceed would be greatly appreciated!

Thanks

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

Hi Dudu2002,

Thanks for the response. I have a Raspberry Pi and a SOIC 8 clip that I am using to read/write the BIOS chip. Here are the commands that I am using:

#####
sudo flashrom -p linux_spi:dev=/dev/spidev0.0 -c MX25L3206E/MX25L3208E 

flashrom --programmer linux_spi:dev=/dev/spidev0.0 \
           --chip "MX25L3206E/MX25L3208E" \
           --read original_4mb1.rom

flashrom --programmer linux_spi:dev=/dev/spidev0.0 \
           --chip "MX25L3206E/MX25L3208E" \
           --read original_4mb2.rom

diff original.4mb1.rom original.4mb2.rom

flashrom --programmer linux_spi:dev=/dev/spidev0.0 \
           --chip "MX25L6405" \
           --read original.8mb1.rom

flashrom --programmer linux_spi:dev=/dev/spidev0.0 \
           --chip "MX25L6405" \
           --read original.8mb2.rom

diff original.8mb1.rom original.8mb2.rom

#####

However, when I try to read the extracted rom with Phoenix BIOS editor, it get the following error:

"No BCP's found!"

Am I using the wrong editor? I thought that the X230t was a Phoenix BIOS.

Hi everyone!

Is there anyone who can modify the bios for my X230 tablet? I'm going to start trying to mod them myself, but I need to get my original Hackintosh project going in the mean time. Here is a linki to the original bios:

X230 BIOS - original

BIOS dump with Universal BIOS Backup ToolKit 2.0:

LENOVO-GCETA5WW(2.65).rom

BIOS dump with FPTw64:

FPTw64 BIOS dump

ACPI dump:

ACPI dump

I'm looking to have the following mods done:

Whitelist removal

Unlock advanced BIOS options

Disable genuine battery check.

I will be flashing with a Raspberry Pi and a SOCI-8 clip.

Thanks!

Hi Dudu2002,

Thanks
for your reply! Here are the dumped files. I did a dump of both the 4mb and 8mb chips first using a Raspberry Pi and then using a CH431A programmer, (I'm trying both to see what gives me better results:

4mb dump - Raspberry Pi

8mb dump - Raspberry Pi

4mb dump - CH431A

8mb dump - CH431A

Please let me know if you need anything else.

Thanks!
