So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...

Good morning, gentlemen, I hope you can help me with my laptop, I told you that I saved it about 2 years ago because it wouldn't turn on, now I have a ch341a programmer, I made a backup of the bios, I flashed an original downloaded from lenovo and it started, but it turned off after a few minutes, I entered the bios configuration and the brand, model, serial number, windows serial number, etc. did not appear, I request your help, I did everything I found in the forum but I could not solve it, also now it won't start again, it turns on but the fan does not turn, I will share all the information...
