[Request] BIOS Dump/Backup of Lenovo T500 or W500

[espionage724]

I have a T500 laptop, and messed up the stock Lenovo BIOS (updated it without updating the EC) and ended up breaking keyboard input which made the entire laptop unusable (couldn't boot any device). Managed to flash Coreboot and now the laptop is usable, but I'd really like to return to the Lenovo BIOS in order to update my EC.

My EC is at version 1.01 (oldest version). I'm pretty sure my laptop is a 7V model (not 6F). Looking at the BIOS update notes from Lenovo, the last BIOS version to support that EC is 2.16-1.01 (BIOS ID 7VET66WW and ECP ID 7VHT12WW), which can be downloaded here. Once extracted however, it provides two relevant files in the 7V folder, $01B8100.FL1 (2.4MB) and $01B8100.FL2 (4.2MB), but neither file reads as a proper BIOS image according to ifdtool, and I'm unsure if I could just flash either of them.

I'd like to flash a T500 or W500 BIOS dump from another laptop in hopes it will allow me to use Lenovo's BIOS update CD to update the EC. After that, I'll go back to Coreboot and be content.

I'd be interested in any dump from a T500 or W500, but here is my specific laptop info if it'll at all be useful:

• The dump can come from any dump tool (Intel Flash Programming Tool, flashrom, SPI)
  
• T500 (no ATI graphics; it seems the W500 uses the same BIOS)
  
• 7Vxxxxxx-based (pretty confident in this; unsure what the difference is between that and the 6Fxxxxxx-based laptops)
  
• 4MB MX25L3205D BIOS chip (it's definitely 4MB, but apparently this is rare and the usual chip in T/W500 is 8MB or 16MB; I'm thinking either it'll dump only 4MB from those chips, or I can remove extra padding to make it fit in 4MB)
  

Here is an archive containing the above last Lenovo BIOS update archive with the two FL files, and a dump of my T500 chip for reference: https://drive.google.com/open?id=1QL13Jp...gLep4G3Gow

I can open both of the 4155KB files in Phoenix BIOS Editor (Not PhoenixTool), but both look very sparse settings-wise and in hex both of the files are probably 75% or more blank (FF). Your "BAD" BIOS opens and looks similar in both Phoenix BIOS Editor and hex (Bit different here, since your dump is actual complete BIOS and contains ME region and other regions not present in the flash files.) But your BIOS also has more options that the flash files, in the BIOS tool so the downloaded files from exe must only be partial flash files.

Here is four dumps from T500, well I guess many are not dumps One Whitelist removed, I think this is modified flash package, similar files inside but different sizes + T500/W500m (8MB IMG file) and a second W500 dump (Also 8MB IMG), and one actual T500.bin dump but it's only 1KB?? Probably not useful, especially that last one, but posting for you in case they help for now, I will look more for a 4MB dump later when I have more time

Hope they help, I'm unable to see BIOS version (not sure where to look)
If you need me to find BIOS version, tell me your BAD BIOS version and maybe I can find in there, then it will help me locate in the dumps too.
