I'm running stock 4.4.4 android on my nexus 5 and I want to unlock the bootloader to flash the 5.0 factory image without rooting or anything. Can I lock my bootloader and reset tamper flag after that and keep my warrenty?
Even with an unlocked bootloader you keep warranty....

Actually I don't, I checked with my carrier.
You'd need root to do this. If it were KitKat, I could tell you the steps but L is different as you need a permissive kernel to have root so once that is replaced I am unsure if we can unroot using SuperSU
I'd recommend in your case, wait for the OTA
I'm sad I have to wait more.. I was hoping I can install the update and then just lock bootloader Getting the OTA update will probably take forever.
Hi All, I currently have an Honor 8 that was previously bootloader unlocked and rooted with TWRP installed on EMUI 4. After I updated to EMUI 5 and Android 7.0, my bootloader was relocked, even though it says my phone is unlocked and untrusted when I turn it on, and I cannot install or access TWRP. I would like to completely reset my phone and reinstall the OS with the recent update, but I have no idea how. How can I do this?
Thanks!

Hi, your bootloader is still unlocked but after instal EMUI5 was reflashed recovery from stock firmware. If you want reinstall / reset your phone and relock bootloader, you must do rollback to MM and after this will be your bootloader relocked. Another way is manually relock, bootloader via fastboot. On my opinion the first way (downgrade to MM) is better for you

I'm sorry, I have no idea what you're saying. What is mm?

So you're saying if I were to roll back to marshmallow, my bootloader would be relocked and my phone wouldn't be so broken. And then I would directly update to the new version of android? If so, how would I do that? Thanks!
Hello all!
I attempted to flash a ROM and failed miserably. Luckily, I managed to get the phone back to the stock ROM. However, the bootloader is still unlocked, and I would like to change that. Ideally, I would like to put the phone exactly how it was when I first bought it; eg. locked bootloader, no root, no custom recovery, etc. Or as close to it as possible.
Is this possible? If so, how can I achieve this?
The model number is : MHA-L29
The build number is : MHA-L29 C567 B190
fastboot oem lock? Or a similar command?
If you want locked bootloader, you have to reflash your phone using this link. Don't forget to make a backup, because it'll delete all your user data.
okey..
I used fastboot oem relock [password used for unlocking bootloader] and it worked without issue. Just be warned that on the Mate 9, locking the bootloader caused mine to factory reset.

Hi, is It possible to relock bootloader for to have warranty back?
Thanks
once you flash the stock img, it will be locked again.
Till Nougat, we had dload method which locks it fully (other method for unlocking it would just re-lock it)

Hey, i am in the same situation and after flashing the stock rom + stock recovery my bootloader is still unlocked, and i still get that "This device has been unlocked and can't be trusted" screen on boot.
Is there any way to manually lock the bootloader?
Edit: i found this SRKTool and i was able to easily relock the bootloader. You need the Unlock code though and it resets your phone, so backup your data.

Yes it will only relock the bootloader but not lock. Anyone experienced with this can get this that you had unlocked your bootloader earlier

Many people say that if we flash stock rom the bootloader stay unlock. Or i have to flash in a particular mode?
With the tool i can relock but not lock, right?

Yup
i Read somewhere that if u flash the stock rom using dload after u have relocked the bootloader, the bootloader status will change from relock to locked. does this work? can anyone try and confirm this? i want to make sure of this before i unlock. I would be greatful forever.
Thanks

Have tried to this more than 100 times and it works fine. It will be locked BL rather than relock

No I haven't even unlocked the bl yet. I just wanted to make sure it the relock to lock state was possible before I unlock. I will do so soon when I get some time.

Yes you can always do via full ota or flashing the stock firmware via dload. Not hard to do to retain warranty:silly:

Use the first file, update.zip. it will contain a update.app file around 3 GB. Can use this single file.

Really? And I have to install over the same firmware, not an update? For example, now I'm on 162 build with unlock bootloader. If I install only update.zip of 162 build with dload method, I obtain the lock bootloader?

Why you want to relock, to gain warranty?
If so, better dload the current firmware and it will lock it safely.
because, i dont want to see everytime when i reboot my phone,this stupid message, who tells me that i have unlock bl...
i have 8.1.0.151 (c432)
i was downloaded this version when im trying to rebranding.. for official site..
if i relock with this version, the worse scenario it will be...??? brick???
if i dload the current firmware, i will install it with TWRP again? and after it will be locked safety?
and what firmware i must to dload?
Hi,
I am currently on A11 with Oneplus 8T and unlocked bootloader + rooted stock rom.
What is the proper process to lock the bootloader and to get back the stock rom? What are the options?
Can I just factory reset the device?
Thanks,

You're confusing us
You're already unlock+root
Then again ask for unlock BL!
If you want just stock then flash boot from stock that's it nothing else to do
@Mr Hassan sorry, I have just edited the first post. I want to LOCK the bootloader and get fully back to an unrooted stock rom.

That's simple just flash stock rom or boot and relock it

Install the latest rom for your phone from the OnePlus support site using local install. That will overwrite the Magisk patched boot you currently have installed.
After the phone reboots (you'll see that Magisk shows it's not installed) then boot into bootloader and use fastboot oem lock
Then select NO (yes, this is a bug in the OOS bootloader) and that should wipe your phone and bring it up with the bootloader locked.
if you want the easiest fastest way, just use the msm tool for the correct model.
ps. if you dont care about losing your data
