Remove a boot screen that says device has been unlocked

Hello!
I need help to remove/disable/hide a screen that shows up at every single boot, it says "Your device has been unlocked and can't be trusted". Is there anyway to hide it? It makes the boot time slower and I find it very irritating.

No, I don't think that is possible. I know that it was on a old Motorola devices, but not on Huaweis afaik.

It's both not possible.
If you rooted your phone you can't lock your bootloader and with unlocked bootloader you'll get this message. No way to remove or hide it, it's hardcoded.
On Huawei's sight you should be thankful for having an unlock code since they're not providing them anymore. So, write it down, safe it on a cloud, on PC, on Laptop, carve it in your wall and make a tattoo on you forehead, so that you'll never loose it.

If I have a rooted device, then I want to re-lock back the bootloader. Will the device un-root itself? Is it impossible to get locked bootloader with root?

It's not possible to lock your bootloader, or relock, with root.
You can only relock after removing the root completely. At the moment it seems that there's no possibility to completely lock the bootloader without downgrading back to Nougat.

Well, how many times a day do you restart your phone?
It's just a message for a few seconds, you should be more concerned about Huawei's ****ty update politics and the fact that they never will release 8.1 for P10 to fix issues with Bluetooth, NFC and other things. And you also should be more concerned about Huawei's unlock code strategy - they stop providing unlock codes for everyone.
So, the message is annoying but there are some issues produced by Huawei which are more serious.
BTW, this unlock message is present at all Android devices and there are no possibilities to disable this.

That wont work...
Go to terminal in root mode and do
Code:
Setprop sys.oem_unlock_allowed 1
Than you can change the value and its not longer greyed out.

If that dosent work you can also follow the below procedure.
Relock your bootloader. Your phone will factory reset and boot. Then head to developer options and you will see oem unlock is not greyed out. Then just enable oem unlocking and unlock the bootloader. When you boot up again you will see that oem is greyed out but it'll be enabled. So you'll have unlocked fastboot and unlocked frp now.

I haven't gone that far. I've unlocked and then relocked.
Everything fine. I believe it's completely safe if you have complete stock firmware installed ie, stock rom, stock recovery, stock Kernal and all that stuff. Otherwise you'll end up in a loop. Guess I forgot that part sorry.
So I know this is someone else's thread but can you tell me if I relocked bootloader will the service center be able to know I'd unlocked before? I don't have the phone unlocked warning at boot. Just curious.

Some if not all bootloaders nowadays are not "locked" by the manufacturer using a code but are usually "locked" by employing a digital signature and/or a CID (carrier Id) hard coded into the OS. When we "unlock" a bootloader with a code we are simply using a routine written into the loader by the manufacturer to now ignore signatures and/or CIDs of the OS and this allows us to flash whatever we wish.
Sometimes upon unlocking using a code the DS/CID is erased/altered and cannot be retrieved, so not a good idea to relock an altered bootloader.
At least, that is my understanding of it.

That's too bad. Means we won't get back our waranty if we relock it ?. So thanks for the heads up . I'll be careful while unlocking it again (if ever).?

Not necessarily, I doubt if most service centres would bother delving that deep, but maybe some would.

Thanks for your quick reply but do you know any way to get back CID/DS

No, but I haven't delved that deeply into Huaweis bootloaders, but I NEVER attempt to re-lock them.

(Q) Query about bootloader and re-packaging an OTA

hi all,
Just having a thought (might not work but thought i'd ask)
Some OTA's / Firmwares which you can install from the bootloader have the ability to re-lock the device, would the same be possible for the other way around?
I mean i'm on a locked bootloader now cos of the crap i installed which updated me to 9.1, it relocked the bootloader, I can turn on OEM unlocking (FRP) but obviously it remains unlocked.
Would there be a way to repackage a firmware package so that it does the opposite to re-locking?
I think everyone has pretty much given up on Huawei devices, I was just trying to disable zRAM and i can't.
Any thoughts ? Is this a possible avenue? or is this simply not going to work?
I'd guess the latter but thought i'd ask.

Which firmware version relocked your bootloader? I can perhaps take a look at it in my free time.

Nope! DLOAD re-lock bootloader to factory condition, but there's no way to unlock the bootloader with it.
I don't think Huawei will give you the unlock code a second time, but maybe you will be lucky, who knows.
Maybe you can retrieve it from an email from them!?
Edit: You can download your HuaweiID data from Settings - > HuaweiID - > Privacy Center but i doubt you will get the bootloader code from there

I've spoke with them, they said they've not heard of a situation like this.
Bare in mind that this is information that has been passed to me before. Which is a correspondence, they are obligated to provide it regardless.
I don't believe it was in an email and I've checked all accounts

What do I lose when I open the bootloader Redmi K20 Pro

Hi everyone
Question for professionals and experienced people I hope to get a reliable answer on this matter
1- What do I lose when opening a bootloader other than air update and payment and warranty service?
2- Is it possible to return to the official status and receive air updates?
Thanks everyone in advance

Can't say for sure but you should still get OTA; if not you'll get full ROM zips delivered via OTA instead of the smaller chunk/patch updates.
The main thing is banking apps and Google Pay. Widevine should be OK. On mine it's L1 so still A-OK for Netflix/etc.

OTA updates work also if bootloader is unlocked. Idem for payement and warranty service...
If you root the phone it isn"t the same story.
Mine is rooted and OTA updates work. I download the update BUT I unroot the phone before installing it.
It"s possible to relock the bootloader but no need to do that...
PS: Unlocking bootloader resets the phone (Back up what you need before).

Unlock bootloader means no more hd on netflix n stuff.
Widevine stay L1 but netflix will failed to load unless you delete smthing n widevine drop to l3

Read carefully the forum! It seems people had problems by flashing a wrong global rom. I can't help you more because I've got MI9T Pro and didn't read a lot about that.

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.

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.
