I just wondered if its possible to lock the OnePlus 5 bootloader with a custom ROM installed?
I only ask as I know it was possible with the OnePlus 2 previously.
Thanks! :good:
This is more out of interest but why would you need to lock bootloader after flashing a custom rom?

My guess is to bypass the annoying screen before booting. Don't question why they wish to do it just help them do it....
The only way I know how to lock the bootloader is to simply go into the Developers option and disable OEM unlocking. I never done it myself so not sure if this will wipe your phone or not. Just back everything up just in case.

Well it was actually possible with the OnePlus 3. So just asking if it's possible one the 5 because that unlocked bootloader loading screen is irritating lol

They gave you back your warranty, how nice of them
At least we now know there is a way to relock the phone, no?

It is possible to lock the bootloader, but you have to be working at HTC to do it.

I reckon they have some sort of flashing box that just obliterates everything and replaces it with official software.
dont they just have to flash back the original spl, which we dont have?

That's what i think.
Unless someone can get that, no luck. Though it's probably a good thing that we can't relock the bootloaders.
I have a major problem, I need to know if it will be possible to flash a custom rom on a nexus 6p. It seems that it will be hard because of that new bootloader.

What do you mean? Any bootloader version on this device can be unlocked.

Sorry, I'm new to this stuff. I thought they can change the bootloader when you upgrade. Thanks for the help though

The bootloader does get updated. But you can unlock any bootloader, and updating it doesn't lock it again. Take a look at my guide:

Oh, because i was afraid of the phone won't boot because of the android n won't boot if the phone has a unlocked bootloader.

Nope, nothing like that to worry about. The locked/unlocked status won't stop it from booting.
Thanks. I can now upgrade in peace
Thanks for taking time to read my query.
I was wondering if I've to lock boot-loader after rooting ( I just rooted my Oero)
and before looking can I take everything backup on titanium backup and then restore everything after locking ?
I'm I still be rooted?
Regards
Unless you are on the totally stock system then I wouldn't lock your bootloader.

Technically i believe you could and would still be rooted, but I've always seen it advised NOT to lock your bootloader again until you are on 100% stock (right now your boot.img isn't stock since it's patched for root).

So you mean I would not be able to re-lock bootloader even if I had installed Nougat, isn't it?
thats because we are using tampered boot.img. Is it possible in-future we can use original boot.img ?

If you relock your bootloader with anything other than a factory image you will brick your device.

If you modify your device, bottom line, you should leave it unlocked so you can fix things or go back to stock if needed, otherwise you could turn it into a paper weight. Even if root is done without modifying the boot.img, I would still keep it unlocked as there are usually still system changes.

This.
With a modified system or other partition, you risk a brick.
If anything goes wrong, once the bootloader is locked you can't fix it.
DO NOT LOCK THE BOOTLOADER ON ANY PHONE IF ROOTED!!!!!

When I boot my k20 plus I get "cannot verify corruption. Lock your boot loader" it sticks there until I press power. How do I get rid of that without locking bootloader?

K20+?? You are in the wrong thread sir. Please search for your phones XDA forum and ask in the rooting thread there. This is the essential ph-1 forum. Good luck!

Doesn't really matter what phone. If. It were a rocket with a string attached the question would have the. Same answer.

I don't see anything about a phone type in the original question. Only that he asks about locking the boot loader.

Lol you are in the wrong thread genius. I don't know who "he" is but assume you are referring to the OP and in that case "He" doesn't need to mention anything about any specific phone because he is already posting in the right place. The question you asked about your k-whatever phone will most certainly be different for every phone. Good luck and who knows maybe a forum moderator can help you?

MOD EDIT
You are one trippy person ? if you really feel the need to post about your LG phone in the mata thread go right ahead buddy.

MOD EDIT
It's worth noting that the Essential PH-1 uses an A/B partition system so any advice given here would not be helpful in the slightest for devices that don't have the same file system. Quickly doing a search of your phone reveals it's not an A/B partitioned system so following advice here could potentially lead to you actually destroying your phone.
could you lock the BL once rooted if in fastboot mode it lists device tampering = false?
Wonderful reply

Just an opinion, but...there are rules for posting in forums that Dev's, no matter how over worked and underpaid/appreciated should follow as well. Teach by example not proxy. Applaud the calm gentleman who responded with eloquent grammar and poise.

If you patched boot.img (Android 11 stock) with magisk and then lock bootloader... Will that be possible since it's stock rom or it altered because of the boot.img patch?

Okay, I just want to keep root, but I can't do that if I lock the bootloader. So please can you give me a solution, so I do not have to deal with an ugly message whenever I boot!
I want to remove the bootloader is unlocked screen when you start the phone, is it possible is any way?
Btw, I have root and custom rom.

Yes it's hideous and distracting. But for now they didn't find out how to get rid of it. It's probably part of the bootloader which can't be touched unless you want a total brick.

Yes, it's part of secure boot.
It's a requirement.
The screen is there to make sure some nefarious program does not unlock the BL and root your phone without you knowing.
Can't get rid of it.
