This have nothing to do with Unlocking Bootloader. Unlock Butloader now and you will be fine, with 4.3 the camera was fixed.

but on the info about bootloader unlocking it says not to proceed if bootloader unlock is no in service menu i dont wish to end with a brick

Have you tried unlocking? When this has happened on Xperia T's the devices were still able to be unlocked even though that had changed. There is absolutely no risk in trying to unlock an unlockable bootloader, it will just fail in the process and will still boot no problem.
It has never been reported a NO had turned to YES, but some Yes had been turned to NO, and they were still bale to be unlocked.
And before anyone gets excited this is by no means something that can be used to unlocked bootloaders that are really locked, it is just a false reading of the boot status.

Ok, so it's risky. Is not a big problem even if you don't unlock the bootloader but are you sure was saying yes before? this is wired.
You can flash updates and custom roms anyway. Not custom kernels. Sorry.

ok i am going to try to bootloader unlock it and report back
remote command not allowed i am stuck with a phone that i cannot bootloader unlock hope there will be an s-off solution for xperia

Applied ota mm on previously unlocked bl. Is bootloader still unlocked?

I just dusted off my Turbo after not using it in a while. Shortly after powering it on, I was prompted for and without thinking, installed the ota MM update. I had previously unlocked bootloader via sunshine long before this, but never rooted. Is my bl still unlocked / root still possible or am I screwed?

It's still unlocked, if it was unlocked prior to the update.
And congratulations for having the foresight to unlock back when you could.

So that's what I was hoping, however I guess Im not clear as to what I need to do next to load twrp and root. I assumed all I'd need to do is pick up the official guide at section 2 in using adb / flashboot to flash twrp.img, but in trying to do so, I get an error "(bootloader) Preflash validation failed". I also noticed at the recovery mode screen it says "Device is LOCKED". Doesnt that mean the bootloader is in fact locked or is that unrelated?
Thanks!

@jcase, @TheSt33v, what's going on with this guy's phone? If he unlocked via Sunshine, should still be unlocked.

There is no bootloader lock command in the OTA. Myself and tons of others took the OTA with an unlocked bootloader. If the bootloader is locked after the OTA, either it was never unlocked or someone gave it the lock command using fastboot.

Depends on status code, either is wasn't unlocked or someone relocked it.
A number of ppl used mofo and has assumed they were unlocked

At the recovery screen where is said it was locked? I believe it was status code 0.

Recovery does the normally safe if locked or not.
Go check the status code, if it is 0 then it was never unlocked with sunshine

I did unlock using Sunshine... At least I really thought I did. I installed it, paid for it and ran through what I thought was the unlock process a few months ago. I didnt load twrp or root, but I didnt think that was needed before upgrading.

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.

Bootloader Status : Unlocked
In fastboot it says

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.

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).?

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