Yoga Slim 6 14IRP8 bios

[naujguerrero]

My Lenovo Yoga Slim 6 14IRP8 - Type 82WV laptop is not boot up after BIOS update through Lenovo Vantage app.

It display a message box with a question "Do you want to recovery ROM Part? (Caution: Not every OS is bootable in Recovery Mode.)" With a couple of choices as below.


YES, this choice will flash ROM Part. NO, abort Recovery mode and restart system.

Both choices do not seem to work and the same message keeps appearing every time I restart. Even the novo button did not help and displays same message.

Hello,
I was in a middle of a bios update and accidently turned my laptop off. Now, my bios is corrupt and I am greeted with a "Do you want to recovery rom part" screen.

Things that I have tried:
- downloaded "LGCN25WW.exe" bios, extracted it, renamed the "WinLGCN25WW.fd" file to "lgcn.bin" and "Fn+R" bios reflashing -> usb bios got recognised however, got an insyde screen that said "not allow flash, boot guard version verification failed. Error: update bios failed!"

- red the content of the 128mbits and 64mbits rom memory ic, the dump is attached
- programmed the 128mbit memory with the first 128mbits of .fd file and the rest on the 64mbits memory ic -> didnt know what i was doing, probably made it worse, the screen didnt turn on and my power light was flashing one long and two short pulses

- reverted both ic into the orginal state -> back to the "Do you want to recovery rom part" screen.

- actually extracted "LGCN25WW.exe'" using biosutillities -> dont know what to do with the extracted .fd file, i guess i got some hints on the memory location of bios, cert, islfash and platform

Thing that I am going to try:
- Combining the backup with the lenovo bios and flashing it on the 128mbits ic, keeping the 64mbits the same (no idea what I am doing, chat gpt suggested this)

Some help/advice would be appreciated!!

Thank you!!

You were close, the extracted .fd that is 24MB "BIOS-UEFI [0x001E6690-0x019E6690].bin" should be split in 8MB + 16MB, then from your backup of the 16MB you have to extract the DMI data (serial, MTM, model name, Win key), it's encrypted on this model, there are 2 blocks that start with LENV, open with hex editor and copy to the 16MB file after splitting
The range is from 1D9000h-1DAFFFh, I copied it to the attached 16MB BIOS

BIOS Ver. LGCN25WW
DMI 1D9000h-1DAFFFh (on 16MB BIOS)

Try flashing only the 16MB BIOS first

Latest version is LGCN34WW by the way
