Yes, i had gen 2 disk, friend brought newer disk and it worked....

Model is ideapad 1 15amn7 ,the board is 5B21J30218 HLS1C_HLS1D LA-L502P with ryzen 5 7th gen... The laptop came to me for broken hinges and displaying only the backlight on the screen...i repaired the hinges and tried booting and all i got was backlight on the screen,but caps lock worked, so i figured the screen or the flat cable was bad, i had the same laptop and connected the cable and screen from the other and the screen acted same, and original lcd works on the other laptop...so then i started removing wifi card and nvme and it started showing picture and i figured out the nvme was blocking...

Guys i have the same laptop, someone before me tried flashing some bios, but it was the wrong one,because only power button got on for a second and then off...i took this dump from post #4 and injected win key and DMI, now the board turns on,caps lock works, usb mouse works, but no image, not even on the HDMI...So the board works , but no image...I don't know what they did before me, maybe the screen is bad,backlight died or something like that...

Here is the SN 5CD0491ZQ3 and current dump, maybe the dump is for a different processor?? i've attached old dump with only power button...
