Is it possible to re-lock and unlocked bootloader?
I know updating should get rid of an unlocked bootloader, but I still get the warning screen on bootup.
Reason I ask is because I had it unlocked, got an OTA update from Verizon for kitkat, and soft bricked my phone. Got stuck in a boot loop with the unlocked bootloader warning message.
I just flashed back to 4.0.4 using RDS Lite 6.1.4. Id like to reset the boot loader to locked before updating to kitkat again.
It's not possible to re-lock. I've updated to KK and can confirm that the BL is, in fact, still unlocked.
I have read somewhere that when you unlock the bootloader, it actually physically blows some kind of physical fuse. or maybe I miusread it.
Someone had made a special logo.img you can flash to get rid of that message.
Although if you really want a locked BL phone, I'd be more than happy to trade you.

Not that it helps, but in Australia, we do not get the nasty warning message after unlocking the bootloader. And I think that the phones are actually sold with an unlocked bootloader.

After unlocking bootloader message is coming your device is corrupt and can't be checked for corruption but after some time I have reverted to stock and relocked OEM using Nexus Root toolkit but even then warning is coming any way to remove this..

It is highly unlikely that after relocking that message would come. Actually, that message could be ignored if your ROM boots fine.
What does the bootloader display about locked status?

Not that. I meant in the bootloader mode itself. Does it display "Device is Locked" or "Device is Unlocked"?

Unlock it again. Go from scratch and flash the factory image using Heisenberg's guide in the General section. After flashing that, see if it solves the issue.
Using toolkits could be buggy at times. I am not against them, but it's good to flash manually, so that you can keep a track on things.

can I flash without unlocking bootloader because after unlocking bootloader there r some heat issues

No you can't flash anything with a locked bootloader. Plus, it's entirely impossible for an unlocked bootloader to cause heat issues, that's either placebo or a coincidence (another cause).
PS. The title of this thread is useless, you should describe your issue in the title, not create text faces.

OK OK but after unlocking it there is any way to relock it and remove this error message

Yes, of course. Infact that's the reason I asked you about the lock status on the first place. Stock ROM with locked bootloader shouldn't give this warning. It should make it go away.
That is why, I asked you to perform a flash manually. Please refer to Heisenberg's guide for the steps.

Yes, after locking the bootloader the message should disappear. But, I'd strongly recommend leaving it unlocked and just dealing with the message. If an OTA ever fails or something else goes wrong you'll need fastboot to flash the factory images to recover your device, you'll be forced to unlock the bootloader, this will wipe the device and you'll lose all of your data because there'll be no way to back it up first.

Sure and then let us know. And keep the bootloader unlocked, it will help you to deal with a few issues (if any), in the future, as already mentioned above by Heisenberg.
-_____- why do people still use toolkits? Try getting use to Adb; it would save you a lot of time dealing with errors.

There is only one way to get rid of the message, and you have already been told.
The solution is to relock your bootloader. Nothing else will fix it.

It didnt ruin your phone.
Simply reflash the stock images and start over from scratch.
If you root or modify the phone in any way from stock, you will get those messages. They are simply that, messages. They do not affect your phone negatively. Other things you have done (like root, or installing apps from unknown sources) WILL affect the phone.
Flash stock images, relock bootloader and it will be brand new, like the day you got it.
If you dont wish to go back to stock, but want to flash OTA updates when they come out (and you are already rooted) look into using FlashFire.

Hi Guys
I have 3 questions regarding Moto X Style Bootloader unlocking.
Can we unlock the Moto X Style bootloader after locking it after first unlock?
Can this process be repeated multiple times if we need to?
Can we use the same unique unlock key that we received while unlocking the bootloader for the first time?
Thank you
Why would you want to do this?

Yes you can do it as many times as you want but 1: Why would you relock afterwards 2: You will have to deal with a factory reset every time
PS: I dont know about the unlock key but most likely you can use the same
Is there any way to remove the Bootloader unlock warning ⚠ without relocking bootloader?

Theres no reason really to relock it. Once its unlocked, the bootloader will show that it was unlocked regardless if you relock it.

Thanks for your reply.
The reason for attempting to re-lock bootloader is to get the OTA update from Motorola till date, especially Reliance Jio VoLTE support...But if I wish to make any further changes to my phone with any custom rom I should be able to do it by unlocking the bootloader again.
Thanks

You don't have to lock the bootloader to take an OTA. You just need to be in a completely unmodified stock state: stock recovery, unmodified system, no root, etc. Bootloader can be unlocked.

I have unlocked bootloader, TWRP recovery and rooted. If I unroot and flash stock recovery, I will be able to get OTA? Do I need to take care of anything else?

That might work. Frankly I'm not sure. I haven't actually taken successfully an OTA on any phone since sometime in 2013 honestly.
I once flashed this phone totally back to stock. Every partition but logo, and it failed to take an OTA. I don't know if it failed because I had a modified logo, or maybe I had mounted system r/w. Not sure.
Hopefully someone more knowledgeable on this topic will chime in.

The answer is maybe... it depends what you have changed and what this OTA updater script actually checks for.
We know that a stock bootloader (which can be unlocked, that is not relevant), stock recovery, and stock system image are required to take an OTA. If the system image has been modified it can fail, and we know the updater has the ability to see if /system has EVER been mounted R/W and can fail for that condition although so far it doesn't seem Moto is going that extreme.
We do know a modified logo does not affect an OTA, in fact, you can even relock the bootloader with a modified logo so it must not be a significant check.

On my father's moto e lte I received OTA without issue with unlocked bootloader, I just flashed stock image and it was ready to update, btw I'm not sure but I've seen somewhere info that you can change bootlogo even with locked bootloader so I don't think that's the issue.
Btw after you once unlock bootloader you won't be able to truly lock it again, next time you will be able to unlock it without any code so you lose some security in this process, frp won't be working anymore.

You still need code to unlock each time, but it's the same code, and if you relock OEM Unlocking gets turned off and you would have to turn it on again... So if something fails on the first boot after relocking, your f*cked, no way to unlock.
And FRP definitely works if the bootloader is unlocked, it is just much easier to bypass.

You're right sorry
Hey, experts! I have a question. Can I keep the ROOT and LOCK BOOTLOADER?
What I want to do with my phone is,
• Unlock Bootloader
• Revert to Oreo(I'll upgrade later, my phone has some software issues)
• Root
• Lock Bootloader
It's this possible?? Because, techmesto, narender Singh claimed that, looking Bootloader after rooting results in bricking up the phone.
Absolutely don't lock it. He's probably right. Just about everything sends this phone into a bootloop, so yeah, it will probably brick it. Even if it boots, OTA will also almost certainly be broken. You'll have to pay to get it unlocked again.

Hi, I have searched but couldn't find a solution, so here's my question.
I had unlocked the bootloader before and worked fine.
Wanted to go back to stock and lock the bootloader again but made a mistake I guess.
I locked the bootloader and now it gives me the 'corrupt' message. Is there anyway I can get it running again?
Unable to re-install the stock atm because flash-all.bat doesn't see a device.
Who is able to help me please?

Thanks for the reply. Can you help me to a correct link?
I managed to get it into fastboot and then I got it to unlock bootloader again.
Then I tried the Maronofrio install tool. That gave me a lot of "failed" messages on the prompt.
Now the phone keeps restarting with the OnePlus logo, but that's it.
Managed! Resolved.
Thanks again Lycidias
