After using easy installer and successfully installing eOS I ended up with an unlocked bootloader.
It seems the fact that it is unlocked makes some apps fail the security check and won’t work (netflix for example). As I don’t have a good reason to keep it unlocked I would prefer to get it locked again.
Last time I tried, this wasn’t possible due to some versioning rule regarding the installed security update vs the one being installed. This was back in April.
I’ve now waited a few months until several updates are available and I’m looking for official instructions on how to get my phone’s bootloader re-locked.
Is it as simple as re-running the easy installer? Are there manual steps involved?
the official instructions have a section describing the issue of the android security version but does not mention how to manage it after this has happened.
It’s imho even easier (if you have a “fastboot” command on your device - if not you might use your preferred search engine to find out how to install it).
shutdown your FP4
keep “vol-” pressed while connecting the device via an USB data cable to your computer
type fastboot flashing lock
If you want to make sure you won’t brick your device then you can type in fastboot flashing get_unlock_abilitybefore relocking the bootloader.
If the answer is 1, it should be possible to relock the bootloader.
If the answer is 0, you should not relock the bootloader.
Please be aware that relocking the bootloader will factory reset your device (i.e. it will delete all data on it!)
you has also written how easy it is despite me mentioning previous issues like the versinioning rule, which if you knew better is that sets the 1 or 0.
So my issue was already described there, but you mentioned its easier as in that’s not a problem. So I thought you being a moderator probably knew better. I blame myself since at the end of the day im the one not questioning it.
But it is also true that you clearly didn’t know about the versioning issue, that you EDITED original answer with the part of the 1 or 0 and later wrote the message that “therefore I had written” which is a cowards escape.
Again, I only blame myself but maybe next time, if someone puts the effort of explaining what they did and what hasn’t worked, you don’t go around boasting “how easy it actually is”.
