AMITSESetup Decryptor

[shiyab]

Hello,
please help me unlock bios on this laptop
Modell:Epson Endeavor NA520E
BIOS:AMI BIOS/UEFI
BIOS Serial Number: 952006306
Motherboard:Epson 13M1
Secure boot:Enable

The key for the backdoor password is not displayed.
cmospwd failed because after running "ioperm.exe -i" I got the error "StartService function call failed".
I will not be able to access the boot options .
dual boot(Windows and Linux) is what BIOS password removal is for.
Booting from a USB flash drive will always boot into Windows, even if you select a different boot option.
Cmos-Deanimator and others also failed.
Resetting the cmos battery also failed.
afuwin3.rom(10.5MB) is from aptio v ami firmware update utility afuwin64
using htt********************** didn't help.(Result is output.txt(warning binary file) in biosdump.zip)
AMITSEdecrypt.py didn't give me the password.
afuwin3.rom.report.txt and afuwin3.rom.dump is Result of AMITSEDecrypt.py.
I apologize for my English I am not from English-speaking world and I am translating via google translate.

need backup bios

need backup bios

backup of bios may be afuwin3.rom.
This hexadecimal code may be an encrypted BIOS password.(0x072b30~ and 0x03f790)

C7 07 72 44 43 5D 61 E1 62 B8 36 B2 8B 74 E5 AF(16 Characters)
Secure boot is enabled. I can't access the boot menu so I can't change it.
Also, I cannot flash the BIOS from FreeDOS.(FreeDOS cannot be booted with UEFI.)(Use afudos)
And, In the case of afuwin, it fails due to an ffs checksum error.(In the case of afuwin, it fails due to ffs checksum error. (Include in the case of a dump(backup?) where nothing has been changed)

@Cvsle1321
Seems like the password cannot be recovered as it's hashed in AMITSESetup variable, only the first SHA256 half is stored there. I've searched for the hash in a database without any match. It also seems like the password maximum length is 8.
