Hello, i just noticed the "OA3 ID" and "Preinstalled OS License" vanished after the bios flash, when installing a fresh copy of windows 11 it asks for a license key (before it didn't). Also the OA2 is now at "No" instead of "Yes". Is there a way to bring it back? I have a photo of the numbers that were under "Preinstalled OS License" and "OA3 ID".

Copy it from another bios to yours using a hex editor. 45 56 53 41

Clean the ME firmware and it should fix the slow running https://www.badcaps.net/forum/troubl...22#post1622422

[etaho]

Hi, unfortunately me too did NVRAM clearing while Hackintoshing and so bricked my Thinkpad L590.

Already been able to restore/flash BIOS (CH341A & AsProgrammer) with the outimage.bin.zip (13.76 MB) volinakis did so kindly posted .. many thanks for it

Currently now only missing OA3 and preinstalled OS Licenses .. as those been wiped out from BIOS settings

Luckily did record of them prior - Also believe have located those details from original bios bin file & done some copying over to outimage bin file

Preinstalled OS License SDK0J40697 WIN .. seems common to many other so not specific to my laptop & win lic
OA3 ID < 13 digit number > ... seems specific ID of my laptop maybe embedded authorize for Windows license


So have copied (from the original dump) and added those LIC and OA3 details to outimage bin file (w Hex editor) .. so ready to test if it would do the trick
= Copied two sections having a.) LIC and b.) LIC + OA3 key + full Win Lic long format (XXXXX-XXXXX .. of 5x 5digits) .. visible

Questions pls help me
1.) How to insert ONLY those missing BIOS lic details ? Wonder if safe & easy way existing like with Lenovo tools / Win PowerShell commands
2.) Pls guide how bin file copy and editing should be done .. if not correct = Are any other specifics to be copied etc..


Here are my Laptop details with original bios file
Model LENOVO L590 ThinkPad 20Q8 S0EL18
Serial PF277J2M
BIOS 1.33 (R0ZET55W)


== Pls. kindly fix/adjust it to fully operational would be really really great
