[Lubazi]

Hello i need bios and ec dump for
Yoga 7 14ITL5
S/N: PF253Q07
Modell: 82BH004XGE

The two attached BIOS files work but the two USB-C ports do not work and I cannot charge the device.

try. Archive.zip is your original bios with clean ME, F5CN64WW.zip is extracted bios from update with your DMI.

Thanks for the files, unfortunately it still doesn't work I tested both
I don't understand, the two Thunderbolt ports work perfectly. Only charging doesn't work

If you have an SPI bios programmer make a backup and post it here,along with the laptop serial number. If you don`t have a programmer you could try a bios recovery

You`re not the only one to have the same problem,its happened to others and with different models

I was able to do a downgrade to version F5CN57WW using the Crisis method described here: https://www.reddit.com/r/Lenovo/comm..._14itl05_bios/
Here is the F5CN57WW firmware if you need it (https://1drv.ms/u/s!AvPnrDOGjsUMgY0S...b0ZBw?e=YfTxcd), I renamed the BIOS.fd file to F5Crisis.bin and it works like a charm.

Attached is the F5Crisis.bin ,extract it from the zip folder and read the instructions at the reddit post

thanks for the bin. it works, then i updated to the latest firmware and as before i can not access the bios again. because i cannot use the previous bin file i've search for a newer one and recovered again. i think the issue is the sequence, need to install the intel management engine firmware first before updating the bios
