Hi,
Some time ago I unlocked the bootloader and rooted my device. Didn't know it was possible to root without unlocking the bootloader (yes, i'm quite new to rooting etc.). Now my phone has a defective headphone-jack and I need to send it on repair. Anyone know how to re-lock the bootloader so I still have the warranty?
Currently running sLIM 4.8 by Wajk.
Use flashtool
Thanks, but it says on Sony's website that the phone stays unlocked even after using flash tool?
Code:
fastboot oem lock
Never done it in Sony phone but most of HTC, Nexus and few other brands I'm locking just with this command.

3 moths ago I have bought this device from the person, which said to me that the device is a Developer edition. The device had pure lolipop on it.
The device could be unlocked just using fastboot oem unlock. I have unlocked the bootloader, flashed couple of roms but I needed to get back to stock because I needed to send my phone to the waranty because of the camera isssue. So I have relocked bootloader and restored backup and send my phone for repair.
In the servis they have succesfully repaired my phone and send it back, but with HTC Sence kitkat rom on it. I have asked them why and they said that they had this phone in database as normal edition. I have tried again to unlock the bootloader using fastboot oem unlock but it was inpossible. I needed to get the token from the htc webside to succesfully unlock my device which I found really strange.
How it is possible that one time, device can be unlocked using fastboo oem unlock and second time not?
PS: It should be in QA thread, sorry ...

Only GPE variants of the M7 can be unlocked using "fastboot oem unlock" all other variants must use HTCDev.com. The stock developer edition have its bootloader factory unlocked.
Developer Edition M7 are also running Sense, the only variants not running sense is GPE.

Phone was probably a converted GPE edition. Then they have restored the original version on the phone, including the corresponding bootloader which can not be unlocked using "fastboot oem unlock"
I got my H9L 2 months back and had rooted it (and unlockedd bootloader). Im having a big battery issue battery drains too fast. I want to get it to service centre as waranty is not over.
I've read posts saying if I relock bootloader I'll get waranty back but some says I won't get back warranty even if I relock bootloader.
Can someone sort this out please
IF you've unlocked the bootloader and rooted the device you have no warranty in the eyes of the manufacturer, it states this in the terms and conditions when you get your bootloader code from them.
See when you unlock the bootloader you get a warning screen upon booting the device and relocking the bootloader will not get rid of that warning.
However have you tried to see if the battery issue is intact an software issue. I.e have you wiped caches, checked if an app such as Google assistant WhatsApp Facebook is running in the background. Do you have the same issue when booting android into safe mode????

That's strange. I've relocked it today after flashing compete stock using HuRupdater tool.
I'm not having the warning screen I had earlier when my bootloader was unlocked.
So does that mean I'll be able to claim my waranty now?
And I've tried different ROMs the issue persists.
If they ask if I've unlocked the bootloader(since I've given my product number they might know) I'll just tell that I took the unlock code just in case, as they were shutting it down and that I haven't used it. Well at least that's the plan
So will they know that I've unlocked it earlier if there is no warning screen? As I've told I have complete stock firmware including kernal and recovery like @Fredin_ told.
Please reply fast.
If your no longer showing that Warning message after going back to stock then you can try and claim warranty if you wish, however they might have other ways to finding out if the bootloader has been unlocked.
So put your claim in and see what they do, they will either honor the Warranty or not Honor the Warranty and give you a quote for the work.
Personally if i unlock my bootloader and root it i'd just put up with the issue as i fully knew that the warranty went when i unlocked the device.
But i will leave it upto you how you go about it.
Hi all,
I've purchased a used P20 Pro from a friend which has an unlocked bootloader and has been previously rooted. I normally keep my phones stock so I want to lock relock the bootloader (I have the code) but despite trying to follow various guides I have been unsuccessful.
Would anyone be able to guide me through the process of relocking the bootloader please?
The main reason I like to keep stock is manufacture updates etc and I don't have the knowledge to maintain a rooted phone.

I don't believe that an unlocked bootloader will prevent you from getting updates. As far as I know the only difference is the warning you get when you boot that "you can't trust the phone."
IF YOU BRICK YOUR PHONE IT'S YOUR RESPONSIBILITY
Don't know if there is another way but of you have fastboot and adb you can do it:
1. Make sure developer options are enabled
2. Connect your phone to the computer using USB cable.
3. Open a command window and type 'adb boot bootloader'
4. Once the device has booted into the bootloader mode type 'fastboot oem lock'
This WILL ERASE all your user data and you will have to configure everything from scratch. You will need the unlock code if you ever want to unlock it again so make sure you don't loose it.
Hello
i have to sell my device so i want to get it to stock again.
My current Setup:
Bootloader Unlocked, Stock Recovery, Rooted with Magisk, Stock ROM 9.0.0.283
What are the Steps to go Back to Stock and wipe everything?
Ive read that if the bootloader relock again it is not able to unlock the second time? Is this correct? I want to get the Unlock Code to the person who buy it but if its real, he cant use the code anymore..
anyway is it possible to do the job with the Stock E-Recovery in the current state of my phone? Without bootloader Relocked? Or is it necessary to relock the bootloader again?
Thank you very much

Ask the buyer if they want it locked. Personally it wouldn't be worth my time if it couldn't be unlocked again. Better to check first..
If you want to lock (not relock) bl justdownload your adequate firmware from androidhost.ru and flash fw using Usb-otg method.
You can unlock/lock your bl using unlock code anytime you want (provided you haven't changed your mainboard in the meantime).

I thought you wanted to go back to stock. I've already gave you solution to bring back all the way stock.
I m not sure if it's even possible to re-lock bootloader using fastboot when you're on pie.
Bootloader status re-locked still means your warranty is void.

Hey I've tried this otg method but without success
If I try it with the dload folder option and try to force flash the emui updater throws an error.
Even with the dialer code method.. same..
I'm not able to get it to stock.
I've tried the Huawei suite on PC and phone in fastboot mode..same..massage this phone can't be reset or so..
What can I do next?
Current state, halfway working phone that's boot into os 2 times from 10 reboots.
Hi all,
My latest Nokia 9 Pureview got from eBay is unbock bootloader ready, so it cant get OTA update. So have any method to get it to re-lock for got OTA update?
Thanks for help and support
Wait... Is that possible to unlock Nokia 9 bootloader? I think that no way to unlock it in the first place.
Are you sure it's bootloader unlocked? Usually when eBay sellers say the device is unlocked, they mean it's not locked down to a specific carrier and can be used with any. Not sure about Nokia's policy on manually updating the device, but no tools exist that I know of for that.
I tried to unlock bootloader on Nokia 6.1 2018 and it works. Google it how to locked bootloader . You will get the procedure
Type this command in adb and fastboot
fastboot flashing lock
