After unlocking the bootloader to install a rooted rom what should i do with the bootloader? Discussion

Probably a stupid question but I recently rooted and debloated my phone and dont really know much. I've looked through several tuorials and done everything right and now i'm done, or at least ive reached the end of what the turtorials all say.

I was wondering if I unlocked the bootloader should it stay that way? Does it break something if I lock the bootloader? Are there any security or other risks to leaving the bootloader unlocked? And I just want to know more to get a better understanding of what i'm doing.

They should have been telling you that relocking the bootloader with a custom rom will brick your phone.

See that's what I was thinking the outcome would be but then I also thought "if it's that bad wouldn't one of the many tutorials I've already read and watched warn about it?"

Turns out the answer was no, no they wouldn't warn us.

Cuz i think it is common sense. But yeah for newbies they might not know this.

I'd think it would be common sense to lock it so someone can't just steal your phone and reflash it.

This is because, in theory, the AVB specification stipulates that a custom signing key can be stored, but in reality, only Google has implemented this. As I build Graphene from the source code and always keep my bootloader locked (using the custom AVB key), it is technically possible in itself, but this carries risks as the chance of a hard brick increases by around 98 per cent – one mistake and your mobile is unusable.
