[REQUEST] Lenovo Thinkpad X230(i) (G2ETxxWW) Whitelist Removal

[pooky1102]

   

Ok friend,
I need your Firmware FULL_DUMP :

dump your Eeproms :

    --- Flash Devices Found ---
    MX25L6405D    ID:0xC22017    Size: 8192KB (65536Kb)
    MX25L3205D    ID:0xC22016    Size: 4096KB (32768Kb)

and I will rebuild your Firmware, then allocate your Bios_Region and replace
Bios Mod into It and I lately upload your files to re-write into Eeproms.
Regards

Hi BDMaster,

How do I dump my EEproms / "Firmware FULL_DUMP"? Do I need the EEPROM Programmer first (waiting for it to come in..)?

Yes I know,
i adviced to You as before do anything You have to read all Eeproms !
I will upload quickly your Bios Mod here, but It needs to integrate into
your FULL_DUMP Firmware.
Regards

Okay I did a full dump.

   

download link: here

This is good?

Full what ? This is the Bios Region Backup !!! like before !
There needs two files read from any Eerom Chip so :

--- Flash Devices Found ---
MX25L6405D ID:0xC22017 Size: 8192KB (65536Kb)
MX25L3205D ID:0xC22016 Size: 4096KB (32768Kb)

1. 8192 KB MX25L6405D
2. 4096 KB MX25L3205D

Then the wor will be possible !
Regards

I have to check the X200 Bios Mod ad compare with X240 then I will comunicate the
differences !

hi,any messages?

Sorry I understand now. You need the dump from both files. I only upload Bios region (8192 KB MX25L6405D).

How do I dump (4096 KB MX25L3205D)?

You wrote " Waiting for the EEPROM Programmer and SOIC8 Test Clip to come in.... "

So I thinked You are using the SPI Programmer to read the chips !
It's possible only using SPI PGM !

Yes I have EEPROM Programmer and SOIC8 Test Clip. I tried to read chip but keep getting error:
   
So I desolder the chip and tried to use SOIC8 Test Clip but same error. I think the SOIC8 Test clip is BAD.

I put chip on PCB and reads good.
Here is file MX25L3205D ID:0xC22016 Size: 4096KB (32768Kb) file

Thank you BDMaster!

I flashed the chip, soldered it back to systemboard, and crossed my fingers. Everything works!

Transfer speed comparison:

Before @ 144mbps:
   

After @ 866.7mbps:
   

Cheers!

I want to report success using your methods and files - indirectly. I also used a RasperryPi with a $5 SO8 clip and the flashrom tool.

I'm no x86 guru, but fully understood the rest of the procedure. The part I needed to work out was the actual BIOS modification:

• I used PhoenixTool to compare the changes between JimmyZ's original upload and BDMaster's modified version of 2.63. I found the 7904 byte module that was changed to remove the whitelist.
  

• Next, I analysed a software tool dump of my original Lenovo 2.59 bios and found the same 7904 byte module with the same MD5 as JimmyZ's - different filename though. Finally, I updated to Lenovo's standard 2.64 BIOS, dumped the result and found the same 7904 byte module with the same MD5 and same filename as JimmyZ's. Lenovo apparently doesn't change this code too often.
  

• Using PhoenixTool, I merged BDMaster's modified module into my 2.64 dump.
  

The SO8 clip worked very well for in-circuit programming. I left VCC/3.3V disconnected, using just MISO, MOSI, CLK, CE and GND. These data lines have resistors between the flash chip and the Intel chipset, meaning you will have no problem driving the flash chip directly in-circuit.

The X230 will power up the LAN/flash 3.3V domain with the computer turned off if Wake-On-LAN is active and an AC source is plugged in. You need to activate WoL in the BIOS and (in my experience) plug in a live Ethernet cable. If the X230's RJ45 lights are on then the flash chip will be supplied with a safe 3.3V in the way that Lenovo intended.

PhoenixTool method: https://www.bios-mods.com/forum/Thread-S...0#pid62410
RaspberryPi flashrom: https://github.com/bibanon/Coreboot-Thin...spberry-Pi

The standard 8-pin SOP package from the MX datasheet quoted on the Coreboot page applies to the X230.
I tried flashrom SPI speeds of 512KHz and 2048KHz. Both worked 100% reliably.

Nice work
Many thanks for your report my friend !!!
