How to remove unlocked bootloader warning on startup... any ideas?

Just annoying to see, is there any way to remove that startup bootloader unlocked warning?

for now no way to remove this message , btw you can relock bootloader and unlock when needed that would help no need to always unlock

pls I need help
Model : LLD-L21
OS : KangVIP Rom (EMUI 8.0.0)
Bootloader Status : Unlocked
In fastboot it says
Phone Unlocked
FRP Locked

did u try dload method?

yes I tried dload
It did not work

I can't upload zipI will send u the file to unlock frp or you can find that file in telegram group of our device

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.

Never Ever a good idea to try and relock the bootloader.

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.
I don't know...........

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.

Have You tried factory reset? I've read somewhere it helped some user, but I cannot find it at the moment.

But when you relock the unlock code no longer works, is that correct?

Yes due to FRP, some people say they have had success. I think best way around it is to use DC Phoenix and use the unbricking method, they do have frp removal but I haven't tried it yet

Thx. I try to figure out what could trigger frp lock. I guess it was factory reset from recovery level.
Theoretically factory reset from settings should remove it.

any help to fix ?

Relock bootloader VOG-L29

Hello
I purchased the device of the title already unlocked and would like to return it to stock rom and lock the bootloader but I don't have the unlock code. I followed a guide found here using an otg cable and a pendrive to return to stock in hopes that it would also lock my bootloader but it did not. The procedure completed successfully twice, 1st going from .178 to .185 and second attempt from .185 back to .178. Every time the phone was factory reset but the bootloader remained unlocked. Any ideas on how to relock the bootloader on this thing without having the unlock code?

That's very strange, service firmware always lock bootloader but in your case it can't. Anyway I have two suggestions for you first go to developer option and uncheck OEM Unlock option then try dload.
Second is try this method Thread Link Click here. Third and last use erecovery for stock firmware restore.
Hope this will help you.
Thanks,

Hi did you tried above methods? What's the result? If not try TWRP tool which I've suggested you.
Another guide for you follow this link CLICK HERE.
I personally advise don't lock bootloader, if you don't know code ask your seller for it.
Thanks,

Hi. I'm in the same situation. I have a Huawei P30 Pro that came with an unlocked bootloader. The yellow message at startup is really disturbing. I would like to relork the bootloader but in vain. The fastboot oem relock command does not work. I flashed the firmware in ota and also by erecovery but nothing works. Recently I noticed on the back of the phone the inscription NOT FOR SALE. I don't know if it has anything to do with it or not.

Hi guys,
Sorry for this stupid question but how do you check your bootloader status on this device?

fastboot oem relock command need oem bootloader code.
you can try with full ota upgrade via OTG via Dload metod. long press the volume up key + volume down key + power button.
Choose the right firmware ,same country of your PHone (example europe C432).
But you are very lucky to have an P30 pro unlocked...don't relock.....

i can't do this cause the OEM is disable in the system options. I'm trying to find a way to get a unlock.img but the zuk site isn't working.

But why you need this option?
I flashed CN ROM, then I blocked the bootloader. When system got bootloop i just flashed CN ROM again with the help of this guide https://forum.xda-developers.com/z5-pro-gt/how-to/guide-unbrick-guide-lenovo-z5-pro-gt-t3915945
