(09-12-2022, 10:00 AM)hovatekspenser.cresencio Could someone explain the source of rsa4096_vbmeta.pem ?? Where can I get it?
How can I generate private key for my own tablet?
You can't generate it. rsa4096_vbmeta.pem is a default private key used by Android. Some brands retain it while some (mostly established brands) change it. Chances are that Nokia changed it. This is why bootloader unlock might fail
Hello Friend. Is it possible to extract desired vbmeta out of payload.bin ??? If yes what will it be ? Vbmeta, vbmeta_system, vbmeta_system_ext, vbmeta_vendor, vbmeta_product or vbmeta_odm ??? Thanks in advance.

That isn't the correct address. Copy the address from the folder

Is it possible to retrieve Private Key from ROM image itself? You said it leaks.. but didn't say where..
Guide with extraction of vbmeta keys was very interesting process but didn't gave required key for bootloader unlocking ..
I hexed vendor.img also, it contain data structures that look like a keys but there are too many of them ..

You can't get private keys that way. They're called Private Keys not Public Keys for a reason

OK.
Nokia has a tool called HMD DeviceKit , on first sight it completely useless as it requires authorization to HMD servers but might be interesting for developers like you.
It has modified fastboot and adb tools in the root folder: files are larger and have some extra abilities.
it passes trough an auth process
fastboot oem auth_start
Uploading 'auth response'

fastboot oem permission flash BoXfIwrqAvS0bjLWp[truncated]DQwWoTnq6spg==
Maybe it is possible to override/bypass validation process ???
quick overview is here: https://hmd.fandom.com/wiki/HMD_Device_Kit
