I unlocked OEM and started the bootloader, but the installer says: “installation of user-specific operating system on your device not authorised“
Which steps could I have forgotten or could I do any change of my settings?
Thank you.
That looks like you have not successfully managed to unlock the bootloader. Check in Developer options to see whether OEM unlocking is allowed.

Yes OEM unlocking is allowed, but now I have the problem that when the installer is ‘Checking Security Patch Level’, I get an error saying ‘Cannot get security patch information’.
Perhaps someone will tell me if I am wrong – on the FP4, Bootloader screen, I think the bottom entry will tell you if the device is still locked.

Oh, Yes you are right. When I start the FastBoot Mode there is written in red “ DEVICE STATE - locked“.
Theoretically, then, I have made a mistake.
However, the steps to be taken beforehand are very clear.
( Unlock developer options, then allow USB debugging and OEM unlock, I have not created any accounts, so I skipped this step).
Is it also possible that there is a bug in the current version of the installer, which is why the installation is simply not possible?
These two posts may inspire ? I think we could blame Mac ?
