About OTA updates after unlocking and re-locking bootloader - Samsung Galaxy M21 Questions & Answers

So I unlocked my bootloader a week ago in order to root my Samsung galaxy M21 Android 11 One UI 3.1, but since the steps were unclear and I was kinda scared I just ditched the idea of rooting. So I searched on Reddit and etc, once you unlock bootloader whether you get OTA updates. There were mixed answers, but then I found a thread saying that I could re-lock the bootloader so I went with the tutorial and re-locked it!!! My question is once you unlock and then lock the bootloader again will you get OTA updates or not???

Yup, you should get OTA updates if you flashed stock rom and relocked your bootloader

I actually unlocked the bootloader on my Mi 10T Pro 5G and then after a few weeks I decided to re-lock it. I installed the stock fastboot ROM and the locked the bootloader with the "fastboot oem lock" command. Will I still receive OTA updates? Thanks!

[Q] Official Update after Bootlaoder unlock?

I have read that Sony Phones wont be able to update via OTA update once the bootloader is unlocked. I just got my HTC One and since i dont want to loose all my data, I want to unlock the bootloader right now. Will I still be able to receive the OTA 4.2 update for the one once my bootlader is unlocked?
I dont have experience with locked bootloaders as my previous phone was an old samsung that came with bootloader unlocked(not anymore).
Thanks for the help in advance.
If you have the bootloader unlocked, you will not receive the OTA.
P.s. If you will unlock your bootloader, you will lose all your data
Thank You

[Q] Rooting factory unlocked Moto X

So I've just ordered an unlocked black 16gb Moto X from Amazon and would like to update it to 4.4.2 and get root access. I know there are a few guides and threads around but am confused as to which variant I'll have as all the guides seem to be carrier specific, and whether my bootloader will be unlocked or not...
Also, I think it'll come with 4.2.2. Should I go ahead and do the 4.4.2 OTA update, or will that make rooting more difficult? Can I root first then update?
I'm not entirely clueless about this kind of thing, having successfully rooted and installed custom firmware on previous android phones but this seems a little more complicated.
Any help much appreciated. Thanks!
If it's an unlockable bootloader, just take all the updates, unlock the bootloader, mfastboot your choice of recovery, boot immediately to recovery and root. Done.
Since its not a developer edition, unlocking your bootloader will void your warranty. You can request the unlock code directly from Moto's web site for free.
To root after your bootloader is unlocked, just follow this -> http://forum.xda-developers.com/moto-x/moto-x-qa/instructions-unlocking-rooting-dev-ed-t2649738
Once you get the code from Moto, you can unlock the bootloader at any point, no matter what rom is on your phone. But you might as well either take the OTA update or flash the 4.4.2 SBF to get to 4.4.2 on your phone, then unlock the bootloader and root. (unlocking the bootloader does factory reset the phone, and erases data and apps, so don't go nuts customizing the phone or installing apps until after you unlock the bootloader).
Thanks for the replies.
How do I find out if my bootloader is unlockable? The Motorola site says that Sprint, USC and TMO phones can be done but nothing about factory unlocked ones...
What if the boitloader can't be unlocked?

The SIM unlocked version can be bootloader unlocked.
Follow the instructions and steps to request the code at -> https://motorola-global-portal.cust...e/bootloader/unlock-your-device-a/action/auth once you hit the final submit button, your warranty will be voided.
Awesome thanks, not as complicated as I had anticipated then...
And once I'm on 4.4.2 and rooted, I won't be able to Do any future OTA updates without losing root right?

WTF dude.....
You relocked the bootloader with TWRP? You are really lucky to not have a bricked phone.
Unfortunately for you, to replace twrp with stock recovery and get the phone back to stock state you'll have to unlock the bootloader again as we cant do anything with a locked bootloader.
*>Unlock your phone like you did before.
*>Make sure you have twrp installed.
*>Follow this guide: https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
(just don't put image of twrp in the directory since you are aiming to go stock)

I've unlocked and relocked my BL about 10 times with no adverse effects that i can see apart from after relock BL displays 'relocked'. I've also loaded all 3 different versions of TWRP in between and about 4 gsi images. Now back to stock B136 with magisk 17.1 and BL unlocked again with safetynet passing and banking apps working plus google play showing 'certified'. Why does unlocking and rocking BL cause issue? apart from the obvious full wipe required. Isn't it just a software flag getting set and reset? It's a genuine question cause i really don't know.

Boy aren't you lucky. Some guys have a hard time with relocking bootloader.Maybe you are just lucky or they're doing something wrong.
But how did you flash twrp with a locked bootloader?
PS im also having the relocked status in fastboot. Do you think we can make it back to 'Locked'? Just in case of warranty issues.

once you unlock and relock, you can't received OTA anymore. same like mine. need to try unlock and relock EDL method but I'm so lazy to try
Can't you just flash the full OTA in fastboot? I know you can flash the zip files off ASUS' site through TWRP.
Once you unlocked your bootloader then your IMEI number becomes blacklisted by Asus OTA server. Which means relocking bootloader will not bring OTA back. You are stuck with manual flashing every update with zip or fastboot.
It even stated clearly in the description on Asus website where you download the tool that OTA will no longer work once you unlock your bootloader. Also warranty will be voided once you do it aswell.

I want to go back to stock CN to be able to get OTA's (TENCENT)

HI.
I am currently using the Tencent verions 8/128gb rog phone 2.
My bootloader is unlocked and i am running the latest WW rom with WW fingerprint.
I want to go back to the original factory state so that i may be able to get the Updates via OTA.
I want to go back to the original CN version and be able to get the OTAs
I read in some posts that Once bootloader has been unlocked. There is no way to get ota anymore. Whether it be cn or ww.. even if you lock the bootloader again??? is that true?
Can someone answer/help me get back to the stock/original factory rom.
i have attached the detailed snapshots showing my current version
First you will never get any OTA updates because you unlocked the bootloader.
Second stay on WW better for you no need to get back to CN there is no updates about 2 month ago.

Whats the benefit of locking the bootloader again, when there is no chance of Auto OTAz anyways?

Does not work like that. It states clearly on Asus bootloader unlock tool, doing bootloader unlock will permanently disable OTA updates. Since your IEMI number will be automatically black listed from their OTA server. So even if you re-lock your bootloader you still won't receive any OTA updates.

Don't ask me ask asus. Since they are stating this clearly on their information about their tool.
Also unlocking bootloader does not change IMEI number. That's why doing OTA with re-locked or unlocked bootloader won't give you anymore OTA.
And yes I have seen people saying updates through OTA no longer works once bootloader is unlocked.
