The Bootloader unlocked, is to use Custom rom, if you block it, the root and rom stock, will continue.

Yes you will lose root. I do not know if it locks the boot loader but if it is unlocked I do not think it would lock. Why are you factory resetting, just out of curiosity?

Maybe I sell the phone at somebody who wants an unlocked bootloader, twrp and root.

Alrighty. It may be better if you wipe the phone and then flash the modified stock ROM because it is debloated and you will already have root.

There is no such rom for d405n (there is one for d405...)

My apologies. I just checked and saw that it was only for the D415. Isn't the only difference between the D405n and the D405 was NFC so couldn't it work?

I doesn't work is said in the thread.

No, but if you're using a custom kernel, you'll brick the phone.

Totally Right, check very well what are you have on your phone then do what you want to do. Relock Bootloader can be possible with Stock Kernel only.

[Q] Can you be rooted and have a locked bootloader

I'm interested in rooting my nexus 6. I know that you have to unlock the bootloader in order to root the phone and install a custom recovery. But after all of that is done is it ok for me to re-lock the bootloader for security reasons or will it have any issues?
Thanks in advance.

Why is that the case? I was able to unlock flash 5.0, relock and side load 5.1. Did Google change something in 5.1?

Yes. Very much so.
problem is.. you now have to enable oem unlocking, to unlock the bootloader. technically, you can still be rooted and lock your bootloader. but the problem is that some have gone back and relocked their bootloader(not with root i dont think so) only to find that they cant boot up, that they end up with a boot loop. and then they cant unlock their bootloaders to flash the factory.img, because you need to check that setting first, to unlock the bootloader. honestly, i think someone with root, and twrp, would be able to. if not, you can fix it by formatting a few things(if you have twrp).

If you have a custom recovery installed, then having a locked bootloader is no more secure than having an unlocked one...

Should I relock the bootloader after flashing M ?

NOOO!!!!
To many folks have encountered an issue that soft-bricked their device afterwards.
You will still receive OTA with an unlocked bootloader.

you can relock it (safer) but if you want to flash any new rom later you will loose all your data. cause everytime you flash you need to unlock the bootloader. its up to you

Hang on now, lets be clear about the advice that we're giving here.
Yes, a locked bootloader is safer if a thief were to get his hands on your device. However, locking the bootloader has a whole host of other problems linked to it. For example, if you end up in a boot loop with a locked bootloader because something breaks in the rom or kernel, if you have stock recovery, you can never unlock the bootloader again, without sending it for repair.
I would suggest people using experimental ROMs should keep their bootloader unlcoked to avoid this

If I did lock the boot loader, can it not be unlocked again using NRT ? I'm wondering since this (Android M) is an official release from Google, there should be a way to unlock the Boot loader if someone wants to roll back to lollipop ... Am I wrong in this assumption ?

It's a security feature whereby if you do not have "enable OEM unlocking" set in the rom, you cannot unlock the bootloader. If you don't have it set, have stock recovery then have a rom that will not boot, you cannot set that, ergo cannot unlock the bootloader. If you're going to mess with exxperiemental previews, I would suggest not re-locking the bootloader.

I just checked and the 'OEM unlocking' option is turned on under Dev Options.
So, can I unlock the bootloader and flash back to 5.1.1 ?

Question Relock bootloader

Hello. I wanted to root my redmi note 10s, and I unlocked the bootloader. But after reflexion, i want to cancel it, cause root will not be useful as I thought. Is it possible to relock the bootloader? And if yes, will the process erase all data ? And will everything be back like before? For example, will I be allowed to use Google One, witch doesn't work on bootloader unlocked devices ? Thanks by advance

yes, relocking the bootloader will erase all your data, to do so just use miflash and select the option clean flash and lock

Can I install custom ROMs or recoveries using SP Flash Tool, but without unlocking my phone's bootloader?

Yeah the title says it all. Just wondering if that's possible or not since I'm not sure if I'd have to wait for a week for my phone to be unlocked, while I could get the job done in no time.
If unlocking the bootloader is required, then would force unlocking it using mtkclient work (triggers bootloop, haven't tried to relock it and see if it fixes it)? Or will it only work through official bootloader unlocking?
No, you need to unlock the bootloader in order to flash a recovery over the stock one

You need to unlock first, since locked bootloader will block any flash over system partitions

I meant if I should unlock it using the official method, or using the mtkclient method?
