Thanks, but, in htcdev dont have relock, only unlock boot.

to relock,youll simply use the fastboot command fastboot oem lock
at this point your bootloader will say **relocked** instead of **unlocked** and it will remain so until you run an RUU that overwrites it.

Forgive me refreshing the old threads. I just wanna make sure, cos last time I unlocked bootloader I had to use xtc-clip and it was an irreversible process....so I'm kinda old school here.
If I understood correctly, unlocked bootloader is no longer a warranty issue since it can be re-locked, isn't it? As long as your possible HW-problem doesn't make adb, ruu-installation proces an impassable nightmare, u can easily re-lock bootloader, restore stock ruu (using other words: u can erase corpus delicti and send your handset to service centre, without being caught, am I right?

Sorry buddy, you're wrong!
Once you have unlocked your bootloader (its state would change from "Locked" to "Unlocked") it can be locked again but its state will be set to "Relocked".
You can't restore the original state of "Locked" neither by launching any stock RUU nor by flashing a new version of the bootloader.
Corpus delicti is rather hard to hide, I'm afraid... Your hands are stained with blood and HTC has tons of luminol in its warehouses...

Thank you for clarification! I was hoping that RUU would overwrite "re-locked" to "locked", but I guess that'd be too good to be true

That's the reason for some people to wait for s-off and avoiding unlocked bootloader via htc-dev. But to be honest, Android without root is like a Porsche with max. 100 mph.. not nearly satisfying..

root moto g3 locked bootloader

Hello.is their any method to root moto g3 without unlocking bootloader ? i am on Android M

Nope. Trying to do so with 1 click tools may end up with a brick.
Broadcasted from Zeta Reticuli

Exactly as @Gravemind2015 said. No. You cannot root without unlocking the bootloader. Do not attempt any other methods than described here, they can and will fail, potentially leaving you bricked.

is it possible to unlock bootloader without wiping the whole device ? I have unlocked it before and later relocked back.

No, any unlock will wipe the device doesn't matter if it's the first or 20th time.

Thanks i already knew but hope is the mother of invention right bro ? By the way there is OEM unlocking option under developer option, what is it meant for ? Do i need to keep it on before re unlocking ? I have not seen it before :fingers-crossed:

The OEM Unlocking option is what allows you to unlock the bootloader in the first place. If you are in fastboot mode and have not toggled that option, it won't allow you to unlock the bootloader. As for relocking the bootloader, I'm not sure. Though I can't imagine you WOULD need it toggled for it.

When you relock, it turns the option off... You need to turn it back on.

Will anyone see that the bootloader is relocked?

Hey everyone,
I got my new Honor 8 and as with my previous OnePlus One I just need root.
It's not that complicated to find descriptions how to unlock the bootloader (and loose the warranty), relock it and even get the "locked" status again without (https://forum.xda-developers.com/showpost.php?p=70177996&postcount=7) and with DC Unlocker (https://www.dc-unlocker.com/how-to-lock-bootloader-from-relocked-to-locked) in case I understood everything right.
But the important qustion of course is if one (for example Huawei) can see that its relocked. So first, what does it say if you get the status over the command prompt? And even if it's "locked" there is there any other way you can see?
I don't expect a warranted answer but maybe someone who is firm with android coding or what ever can at least say what he thinks?
Thanks a lot!

If you relock it with a fastboot command then yeah. But if you use a rollback package to return to emui 4.1, everything gets wiped in a way that makes the bootloader status "locked"

Could please someone at least check the first question with his unlocked phone?
Edit: Didn't see your reply and don't now how to delete mine... Thanks anyway!

As far as i know yeah, unless there is some secret way for them to know it. If you unlock the bootloader with a code and then lock it again it will show the bootloader status as "relocked" in fastboot mode, indicating that the device was tampered with in the past. But the "locked" status you get in the rollback process is the same as on a phone that was never modified. I found this "trick" accidentally when restoring a bricked phone using the rollback package and think it's pretty handy.

Not sure if u'll read this. When I was stuck in the same issue somewhere around July 2017 I was devastated and thought if I were to relock my bootloader how to do so without it saying relocked (If you do it by fastboot it will 100% say so). I tried the rollback method on seeing this and u sure r right. It says LOCKED and looks as though my phone was never tampered with ?.
I came across this thread researching abt something and though I'd thank you!

Google Pixel Verizon bootloop, Lock bootloader

I lock bootloader on Verizon Google Pixel when my device have TWRP and i have brick! Device Loading up to logo Google on 1 sec and reboot. Fastboot work, but i don't unlock bootloader. In recovery is don't enter. Please help me!

https://forum.xda-developers.com/pixel/how-to/psa-read-relocking-bootloader-t3494614 ....very important advice. With my limited knowledge NEVER relock unless you have signed OEM images correctly reloaded into device before locking.

Put the phone in fastboot mode, then run `fastboot flashing unlock` from a PC. If it says unlocking not allowed, you're out of luck, it's a brick now. Never lock your phone without being 100% stock on both slots

No idea. I've never relocked unless I am completely stock and take at least one ota first to make sure, along with full factory resets before and after updating.
There are others here that claim they where able to unlock again and save their phones though so maybe it's possible.

I thought the locked/unlocked bootloader setting was "sticky" though. Is that true?

You should now lock the bootloader for security...

Maybe this question deserves its own thread, but
Why is an unlocked bootloader insecure?

Simple, it allows anyone with physical access to your phone the ability to flash basically anything on it. That said, Ive unlocked every device Ive owned immediately after getting it.
