Purchased Used P20 Pro with unlocked bootloader - Huawei P20 Pro Questions & Answers

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.

[Q] xt1053 Unlocked Bootloader Warning on screen but not actually unlocked?

I must have missed a step when I unlocked my XT1053 last year. I never did anything with it and assumed that because it gives the the caution screen when I turn it off and back on, that the bootloader is unlocked. However, now that I decided to get down and do stuff, it's telling me via third party apps that my phone isn't actually unlocked. There's no super user app or anything. Do I need to go through the unlocking process again? I'm on 4.4.4.
Me again. I'm following the directions for rooting it and have flashed TWRP 2.8.6.0 but when I select Recovery, there's a dead android and it says "No Command."
You have an unlocked boot loader but you don't have root privelages.Also try holding down volume down+power on no command
It takes some reading comprehension but the tutorials here really are excellent. I guess I have a philosophical question: why would you unlock the bootloader without the intention of rooting the phone? I had (obviously) confused the terms.

Can you boot the phone into Fastboot/Bootloader mode? What does it say for the status?
If its LOCKED Status 0, then your bootloader is locked. If its LOCKED Status 2 (or 1), then you are "Relocked" (i.e. the bootloader was unlocked, then someone used the Fastboot OEM LOCK process to relock the bootloader). The phone will always show the UNLOCKED Warning message screen if your status is no longer 0. (As users, we can toggle between Unlocked and Relocked, but can't get it back to Locked Status 0).
Since the XT1053 can unlock its bootloader via the code from Moto's web site, you can always just follow the bootloader unlock process again, using the same unique code for your phone.
After your phone's bootloader is showing UNLOCKED Status 3, you may root by following -> http://forum.xda-developers.com/moto-x/moto-x-qa/instructions-unlocking-rooting-dev-ed-t2649738 (Step 8 IS necessary) Please be sure to use the latest TWRP fastboot IMG file and Installable ZIP of SuperSU

Since doing the bootloader unlock process is "desctructive" (i.e. wipes use data/apps from the phone), some will unlock the bootloader when they first get the phone, run with it, and maybe root later... that way when they do decide to root, they wont need to also wipe the phone and have to set it back up from scratch.
But that is the only reason I can think of why one would unlock the bootloader, and not root. At the same respect, if you don't have a phone which is branded Developer Edition, you've already voided the phones warranty by requesting the code from Moto, so, why not root immediately?

Re-lock bootloader

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.

Question Missing OEM Unlock on Cellular VZW S8+ (SM-X808U)

Hey guys,
I've searched the forum but nobody seems to have reported the issue I'm experiencing. The way the posts are worded, unlocking the Tab S8+ is a given. I know the US S22 has no OEM Unlocking officially supported. I've followed all the workarounds to get the option to appear to no avail.
My only theory is that VZW hasn't yet unlocked my S8+ (if it was ever locked to begin with, nevertheless I've owned it less than 60 days). Can anybody confirm if this model can be bootloader unlocked by conventional means either prior or after carrier unlock?
Hi! I'm going to try to find the other user's post who enlightened me in this section, but I might have trouble finding it.
Effectively, no U.S. carrier's version of previous and current Samsung Galaxy Tabs can have the bootloader unlocked - at least that's what I remember them telling me. You have to buy the Wi-Fi only version to be able to unlock the bootloader.
Now - SIM unlock, I know nothing about on the Tabs. Normally no matter what U.S. carrier, that I'm aware of, once you pay off your device (if financed), they'll SIM unlock the device, and although you can relate the two things (SIM and bootloader unlocking), they are completely separate and it's only certain U.S. phones (not Samsung phones or tablets) that getting SIM unlock enables you to also do OEM unlocking, and therefore be able to unlock the bootloader.
Verizon never allows the bootloader to be unlocked on any kind of device, no matter what, and all U.S. Samsung carrier devices - both phones and tablets, are never able to get their bootloader unlocked. I'm not including the rare exception that there's a hack to be able to get root - but most hacks circumvent the locked bootloader - they don't often actually allow the bootloader to be unlocked, and this sort of thing is rarer and rarer anymore.
Edit: I believe this is the post, by @googlephoneFKLenAsh.
Thank you for your thorough explanation. I was expecting the Tab to be the same situation as with the U.S. Galaxy phones, I just wasn't able to find confirmation of that.
I know Verizon is hostile to bootloader unlocking (case in point Pixel). So it was either gonna be my carrier and if not that my region.
Tablets do on rare occasion are exceptions (iirc ATT doesn't carrier lock tablets) so barring an explanation elsewhere I figured I'd post and have that question answered for myself and those concerned.
I don't understand the motivation behind it given that unlocking is already a process that can't be exploited by malware/spyware and carries a myriad of drawbacks/risks.

You're welcome!
I'm not sure I understand what you're saying here, or I'm not sure if you meant to say it differently.
An unlocked (or unlockable) bootloader can definitely be exploited without our awareness.
I agree that I don't understand the motivation - at least in contrast to AT&T and T-Mobile which apparently do allow bootloaders to be unlocked once their phones are paid for and SIM unlocked. I also don't know why or if AT&T and T-Mobile would not allow Samsung tablets to be bootloader-unlocked while allowing other brands.
Overall I think the motivation is the prevention of potentially more problems that users will have and also potentially brick their device and then they wind up with an unhappy customer because the carrier won't consider the device under warranty since it had been fiddled with in a way they're not willing to support (understandably).
Additionally, root malware would potentially be using their mobile network for nefarious purposes.

I have the same s8+ 5G model and I'm unable to get to the unlock option from download mode. I have however managed to turn on the OEM unlock from android. It is very fiddly to get to the OEM unlock option, and it will disappear afterward. The method I used is to quickly go to the developer's options before the tablet fully started after a reboot. It will let you toggle the OEM unlock.
I'm waiting if someone found a way to get the bootloader unlock from download mode. Obviously I have tried all other methods ( e.g> cable + up+down volume )
It's actually not possible to unlock via download mode. Download mode is only used for Odin flashing and the like.
You have to get to the bootloader which I believe is power and vol up WITHOUT using the cable afaik.
If by some catastrophic reason you can't get into the bootloader after that, you can boot the device, enable USB debugging, plug into pc, and run adb reboot bootloader or adb reboot recovery.

Have you been able to get the OEM unlocking switch to reappear after you've already toggled it?
If so, is it still on when it reappears? If it is then there's a high likelihood the device can then be unlocked.

yes, it remains as OEM unlocked. I even tried to see if this could be false positive by flipping OEM unlock back and forth. It has shown the setting is persistence, if you set OEM unlock it will stay unlock. If you set it back to OEM lock. It stays as OEM lock.

You are supposed to boot into bootloader mode and then use the fastboot tool to trigger the unlock.
Either fastboot flashing unlock or fastboot oem unlocking. Something like that.

These are the necessary steps on this tablet to unlock the bootloader - it doesn't involve Fastboot from the Platform Tools. I am aware that on standard Android/AOSP that it does involve Fastboot since for my phones I choose Google Pixel devices.
skrowl said:
Step 1 - Prepare your Tablet (only necessary for first install on unrooted device)​
While Frija is downloading the firmware, prepare your device by doing the following:
Settings > About Tablet > Software Information > Click Build Number 7 times quickly
Developer Options (just below About Tablet on the left column)
Turn on USB Debugging
Turn on OEM unlocking
NOTE: If the OEM Unlocking option doesn't appear, connect the device to the internet, wait a few minutes, then try again
Power tablet completely off (Hold volume down + power button if you haven't changed the Bixby settings)
While holding volume up and volume down, plug the tablet into your PC via USB
Let go of volume keys as soon as the blue-green screen shows up
Press and hold volume up for 5 seconds, the screen will change to a confirmation prompt
Press volume up again to confirm, the tablet will reboot
Unplug your tablet from USB
Go through initial setup. Don't bother copying files or installing anything.
Skip signing in to your Google account and Samsung account. You won't be using them for this step.
Settings > About Tablet > Software Information > Click Build Number 7 times quickly
Developer Options (just below About Tablet on the left column)
Turn on USB Debugging
Reboot the tablet

Ah I wasn't aware that some devices do not require fastboot to finalize unlock and instead immediately unlock when toggling OEM Unlocking.
Is it possible to confirm the unlock by getting the bootloader vars using fastboot however?
Alternately, what's the easiest way to confirm the bootloader is unlocked?

According to this post, you should have your bootloader unlocked now. Could you try following the instructions listed and report back?
Could you also explain in more detail how you can get the OEM unlocking option to appear?
I seem to be having no luck. You do own a US model, correct?

Actually, although the instructions don't make it clear without the context of seeing what's on the screen, steps 5 through 7 are what unlock the bootloader. OEM Unlocking still only (normally) enables unlocking the bootloader:
5. While holding volume up and volume down, plug the tablet into your PC via USB
Let go of volume keys as soon as the blue-green screen shows up
6. Press and hold volume up for 5 seconds, the screen will change to a confirmation prompt
7. Press volume up again to confirm, the tablet will reboot

Also, just as on the Google Pixel and many or all other devices, the easiest way to see that your bootloader is unlocked is the (IMHO) big honking stupid advertisement when you reboot or turn on your device that the bootloader is unlocked and the (paraphrasing) "hey thieves, if you just stole this device, you're in luck because you can hack into someone's account easier since this device's bootloader is unlocked" that stays on the screen seemingly forever.
I know that if they're actually technically savvy they'd be able to find that out anyway, but all this forced pre-boot screen does is punish those who unlock their bootloader. End Rant.
Ah I see what you mean, so It's been stated that US devices either resist BL unlocks e entirely or require alternative solutions.
That being said, has there been reports of UI bugs causing the option to appear on USA models under certain circumstances?

No. I've read every post in this section starting from when I pre-ordered mine (February?), and the only post I've seen about being able to enable OEM Unlocking was from @killerzac.
Too bad that doesn't easily lead to actually being able to unlock, even if the OEM Unlocking aspect was widely reproducible.

Have you found a solution?
I'm in such a weird place. I'm in the UK my first Tab S8 Ultra unlocked originally but after relocking the bootloader I can't get the OEM Unlock to reappear. I needed an unlocked tablet so I bought another one and this one has never had the OEM Unlock option. Waited many sets of 7 days trying different Samsung accounts and Google accounts. I do notice like you that if you get to dev options quickly after boot OEM Unlock is there but it definitely hasn't loaded properly at this point and changing it does nothing. Tablet never gives the bootloader unlock option when you go through the process.
The only thing ive noticed is on both devices the KG Status is Active (Viewed in Download Mode). My S22 which has the OEM Unlock option shows it as inactive. Samsung have told me that I can send the tablet to them and they will look at it but I can't be without it at the moment. Don't know if both my tablets are wrongly reporting that they are in finance and MDM is locking it potentially following my Samsung account to the new tablet I bought.
Really annoyed with Samsung now spent hours on web chats with them where they keep making you reset the tablet and won't escalte it.
Even more annoying they won't look at my first tablet because it did unlock initially so the warrenty is void now that it won't unlock they have said they will replace the mainboard for £800.
@Jono0907 That really sucks! I'm sorry to hear about all the trouble. I "swear" - customer service these days. Someday, companies will just stop even having the (mostly) nearly useless customer service that they do now, and they just won't have any at all.

Hi Jono,
I haven't look at it since and I'm pretty sure your finding is very much same as mine, Quote "Table never gives the bootloader unlock option". I gave my s8+ to my 5 years old son as his toy now. Piece of garbage without ROOTing for me. I'm reverting back to using my tabS6. You might hapend to see me on the northen line with my TabS6, very rare scene.

How to unlock bootloader on Oneplus Nord N100

Hello everybody
I need to know if there is a method to unlock the bootloader for an Oneplus Nord N100 but the BE2015 model (Metro PCS by T-Mobile) because I have not found out how to do it in this Forums
My smartphone is running Android 11 by an update (version 11.0.9.BE82CF).
My goal is to unlock the bootloader in order to install TWRP for a future custon ROM
Thanks to everybody and excuse my English.
Happy 2023
If I understand correctly you have to have the phone for 180(?) days and then "OEM unlock" will be available in developer settings. Then you have to request en unlock token from T-Mobile. (I don't have an american phone, I'm not 100% on the method)
You can get an unstable TWRP for this phone, but it will have very limited functionality. And custom ROMs is basically a forgotten dream on this phone.
Basically what you can do is sideload Magisk through TWRP (you have to use adb sideload command) and some people have installed GSI ROMs.

Really I bought the phone already unlocked, it has the "OEM unlock" function in the "Developer options". Because I didn't buy the phone directly from T-Mobile it's impossible to request the unlock token, so better I continue using it normally until I can buy another phone (I didn't comment but I live in Cuba...)
Thanks anyway for your answer...

I think you might be able to load a European/Global ROM through MSM tools. Then you can use OEM unlock command without token. Rummage through the N100 forums here and you can find guides.

If all you want to do is unlock the bootloader I think you can just do this.
** WARNING: YOUR DATA WILL BE WIPED **
1. enable developer options -> oem unlock
2. start adb
3. adb reboot fastboot
4 fastboot oem unlock
if step 4 fails then try
5. fastboot reboot fastboot
6. fastboot oem unlock
The phone will show a screen to confirm unlocking. YOUR DATA WILL BE WIPED.
7. fastboot reboot
The phone should reboot. Unfortunately It will display an annoying message warning the bootloader is unlocked for quite a while before it boots into system from now on.
BTW: I had problems with twrp 3.5 for Nord N100 floating around these forums. Latest is twrp 3.7 which I'm still suspicious of. All of my flashing using TWRP on the N100 has resulted in bricking.
My successful flashes have been with fastboot.
I use TWRP on another phone and it works like a dream.
Hi,
In step 3, do
adb reboot bootloader
This will reboot in the ancient fastboot, not fastbootd. This is in this mode that you can unlock the bootloader.

Question Help, i did something stupid.

Hello
Hoping somebody can help getting my phone up and running again.
I wanted to unroot my phone, because i was having issues with danish "MitId". And was a bit sloppy with it.
First i tried using SuperSU to remove root. Because i didnt feel like setting everything up again. Didnt work.
Then I locked the OEM Lock in developer settings. Not thinking this would be a fatal error.
Got home from work, and said to myself. Jusk lock the bootloader and the phone will reset itself.
But this is not the case, when you have been stupid enough to lock the OEM lock.
Now I am stuck on "No valid operating system could be found. The device will not boot"
I can get in to fastboot by pushning power+vol down. But cannot flash anything since the phone thinks the OEM Lock is locked on it.
Does anyone know of a solution for me. Or is it going to the shop tommorow and say that my phone is going this. And hope they will sort it for me?
Can't you fix stuff by using https://flash.android.com/ ?
No, unfortuantly not. It fails:
Device Unlock Disabled​For security reasons, you need to enable "OEM unlocking" in order to flash your device. See the device preparation instructions for more information.

Try sideloading the full OTA. You don't need an unlocked bootloader for that.
Unfortuatly not, if I try to enter recovery mode. The phone just goes back to the screen saying "No valid operating system could be found. The device will not boot"
ADB is not available to me
If you can't sideload the OTA, I'm afraid there is not much else you can do with a locked bootloader except try to RMA it.
Can you get into recovery at all. Even if it's the stock you can attempt a sideload of the stock OTA.zip from Google. You may also try if your on boot slot A
fastboot --set-active=b
On b use
fastboot --set-active=a
Try to see if the other boot slot has an a bootable OS.
*****I apologize I just saw it's actually still locked****"
Contact U-break I-fix if I typed that correctly. The third party warranty repair center for Google's warranty. I believe they can attempt to switch the boot slot with a locked bootloader with the equipment they use to reflash these devices. If anything it's under warranty get the RMA and if the bootloader is locked on it trade someone or sell it and use it to make buying a new cheaper..

No, I can get into fastboot and that is it.
But everything I try in fastboot gets rejected, since it says the phone is locked.
Does the bootloader screen on the phone have the option to boot into Rescue. This has a ADB connection but I am not sure if adb sideload works
Really mad that Google intentionally locks phones this way, turning them into completely functional, but useless piece of junk. I guess that's late stage capitalism for you xD

Google is not responsible for phone's with locked bootloaders. They make the device with the specifications the carrier that sells it stipulates. Google themselves allows the unlock.

If you can't sideload the OTA, I'm afraid there is not much else you can do with a locked bootloader except try to RMA it.

Iam guessing the same. Phone doesnt want to do anything.
And since i cant get into the phone to oem lock i am stuck. Live in Denmark, so by law I havnt voided the warrenty by rooting.
Pixel warranty is always valid even if you unlock and root. Google doesn't void the warranty. Go to Google pixel support page. Find warranty and act as if your submitting a RMA and it will tell you after you enter the device IMEI how long your warranty is valid for

If that were true. Android flash tool https://flash.android.com/welcome
Would work as it's the same process for the browser to flash the very same file. Motorola allowed signed factory img on locked. Google had never allowed that in fastboot as far as I am aware

All you need to do is go here Factory pixel firmwares and scroll down to pixel 7 panther assuming you're not on the pro (cheetah)
-select the latest version for your model whether that's Verizon or whatever if you have the carrier unlocked one like myself just choose the Feb firmware that doesn't have a carrier name at the end of the firmware number (you should have your phone plugged into your PC and in fastboot mode) click flash and follow the steps. These are Googles factory images so it doesn't matter if your bootloader is unlocked or not as long as you choose the latest version and the correct version for your phone. Tbh you can't really brick the pixel 7 as long as you have a PC and are able to put the phone in fastboot mode (holding the volume down and power button while powering on)
-Anytime you run into some kind of bootloop issue or wanna get rid of root flashing the stock firmware from this website will factory reset and revert your phone to the way it was the very first time it was pulled out of the box and powered on. If you have already tried this and you know forsure you did everything correctly then I must admit I have never had this happen and I'm someone who flashes custom roms and goes back to stock to get the latest security update just to turn around and flash another custom rom right after lol. If you need any help or advice feel free to pm me whenever. I have been rooting phones for a long time and have to say that the Google pixel is by far the most user friendly phone I've ever owned when it comes to custom rooms, rooting etc. You can ALWAYS go back as long as you know what steps to take. Sorry for the rant especially if you already figured it out.
Happy Customizing!

Their bootloader is locked. You cannot flash a factory image like that with a locked bootloader. They also turned off OEM Unlocking in the developer settings. If they had left this enabled they would be able to use Android Flash Tool as that tool will unlock your bootloader if OEM Unlocking is enabled.

This wouldn't be Google, they basically encourage you too unlock the bootloader and root if you want as they give you all the tools you need and factory firmware options to go back if you make a mistake. Tbh if you are able to unlock and root the phone to start then you can go back. Even with a locked bootloader you can always flash the latest factory image on googles dev website, you just can't downgrade firmware or install different carrier firmware without the unlocked bootloader. If we really wanna poke at some phone developers I vote Samsung as I have had multiple people ask me to root their phones and if it's a US snapdragon version it cannot be done its so frustrating lol thanks for letting me vent, have a great day if you have the the carrier unlocked dev edition of the pixel 7 and ever need any help feel free to pm me. I have been rooting and romming pixels for a long time
Edit: I was not aware you couldn't flash the stock firmare using googles dev page without oem unlock. I apologize for jumping to conclusions. I thought I had every possible bad scenario happen to me by now but apparently I learned something new today.

Dude. You cannot flash factory images of any kind on any Google phone with the bootloader in locked status. Please stop giving false information on here. If you want to talk up Samsung do it on a Samsung post. Let's not confuse everyone please

To use Android Flash Tool, you have to have OEM Unlocking enabled in Developer Options for it to be able to unlock the bootloader.
To flash the factory image in fastboot you must have an unlocked bootloader.

Okay my bad you are right fortunately I have never had this happen. And like someone else said if he can't get into recovery then he can't sideload a factory ota... sorry I'm at a loss on this one. Some custom roms use "fastboot update file.zip" would that do anything in this case or would that command not even work with a locked bootloader I'm assuming. I apologize for trying to act like a know it all I've just never heard of this happening
