Hi peste:
My latop have no SN , buy from CHINA,very cheap, about $600 USA dollor,due to lacking SN model name type etc, so
i want to flash the BIOS with SN MODEL TPYE something lile that, and no lucky, i failed.
But beacuse the spec i saw is is 12700H 32G ddr4 A370 VGA card so it possible IdeaPad 5 Pro 16IAH7 or Yoga 7 16IAH7 (not pro).
Today, i pay $3 to a Chinese BIOS engineer to help me split 8/16 MB flash raw data from Lenova office BIOS update exe file,
and test them this morning, but also failed , now the note book won't blink 12 times, it just turn...

Hi everyoneone:
My lenova note book after power button press, it blink 12 times in white led, check attached video ~
have anybody see this condition?

Before i try flash bios 8M&16MB , it ok, but maybe i didn't backup (read) these flash raw data,
after i write backup 8&16 MB image to laptop again ~ it become this conditions now ,
I don't know if 8M or 16M image is incorrect ~ could somebody have this kind of condition can give me some idea ?

I am sorry, my english is not well ...

Might be write corrupt bios back to note book....
