My ch341a recognizes the chip so I'm confused why it reports corrupted somehow?

[CODE]~$ sudo flashrom -p ch341a_spi -r lol.bin
flashrom v1.2 on Linux 5.13.0-30-generic (x86_64)
flashrom is free software, get the source...

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hi all, I have a Lenovo P51 and pretty sure I found the BIOS chip...it is branded "WINBOND 25Q80BLNIG", but when I use the script it says the dump is either corrupted or isn't a valid dump.

So just wanted to see if someone can help with identifying the correct chip?

Thanks
