Request for the BackUp of Original BIOS File of Lenovo U550

Hi everybody,

I want to repair the bios of a Lenovo U550 (ideapad). It had 23CN18WW. I did upgrade to 23CN21WW. 

In both cases, when flashing the BIOS with a file or the other, the BIOS System Information (F2 panel) is as follows:

Product Name: INVALID
BIOS Version: 23CN21WW (or 23CN18WW when flashed with it).
LENOVO SN: INVALID
UUID Number: 00000000-0000-0000-0000-000000000000

So this files don't work for me (and I think that is not a solution suitable for nobody).

In internet there is a file named "LENOVO-IDEAPAD-U550-LU15" but is the same "23CN21WW + 23CN18WW". 

I used INSYDEH20 dos bios update tool (I have downloaded it from insyde.com, it is original and perfectly working).  The original name is "H20FFT-D.exe" but I am renamed it "bios.exe"

1. Create a dos bootable USB disk (Fat32): Format The USB stick to Fat32, download and add the content of Win98Boot_Files.rar (COMMAND.COM, IO.SYS and MSDOS.SYS) to the USB stick: 

https://mega.nz/#!TcVgUSjD!R1AxpyWuAtFMA...tgqKsWWkno 

2. Dowload & Copy "bios.exe" (originally named "H20FFT-D.exe") from the link below. I think it will work with all INSYDE H20 BIOS.

https://mega.nz/#!ncc3BIxK!I7_xhb6_UGZ6c...NNXNW9gKeE

3. Add to the USB stick your Bios Firmware (xxxx.bin, .img, etc). If you have a .fd file, if necessary try just rename it .bin .

4. Plug the USB stick to a USB slot in the side where there is VGA - HDMI connection. If will not work ensure thath is not a USB 3.0 slot (blue color). Boot your system from USB. 

5. The command is:     

bios.exe xxxx.bin      

(or your bios file type: xxxx.img, etc). Just wait a pair of minutes. The system will Upgrade the BIOS and restart automatically having done the job.

What I need it is:

A copy of the backup of an original BIOS Lenovo U550 (ideapad). You can easily get it in seconds using "Universal Bios Backup Tool 2.0".

Universal Bios Backup Tool 2.0.exe link:
