So has anyone tried to relock the bootloader? It would be nice to know if there is a method to relock that can't be detected, so our warranty says intact. I've read that dc unlocker can do that but I've never seen confirmation.

I've just checked too on dc unlocker site and P9 results like the last added supported model with this features:

- direct unlock
- read bootloader code
- read unlock codes
- unlock FRP

So I just unlocked my Bootloader successfully with the DC unlocker tool and wanted to share the process with you guys. If you live in Europe and tried to get your unlock code directly from Huawei you may have run into some problems ;) but this method works. My P9 is a EVA-L09 (europe single sim version).

Do this at your own risk.

You need this tool: https://www.dc-unlocker.com/ I did it with the most recent version as of now (V1.00.1290) which is the first that supports the P9.

Basically follow the instructions in the tool to get your device connected, it's straightforward. Then you need to make an account and _buy_ credits to read your unlock code. You need 4 credits so it will cost you 4 euro. This sucks, but it's no scam or anything. It works (as I just did it).
Just log in through the tool with the data provided after making an account and go to Unlocking -->"read bootloader code". Push the button and after a few secs your code appears. WRITE IT DOWN AND/OR COPY IT TO A .txt or something ;)

[e] important: before you unlock/relock your phone or flash a custom recovery make sure that you go to developer settings and tick "enable OEM unlock". Missing this could lead to brick in certain situations, for more info read this article and do additional research.

Once you have the code you can start the unlocking process. This is the same for people that got their unlock code through other methods.
-Disconnect and power off your P9.
-Push volume down and connect it to your Computer, when the screen turns on you are in fastboot mode.
-Open any ADB/Fastboot tool (http://forum.xda-developers.com/showthread.php?t=2317790 <- i used this) and write:

"fastboot devices"

your device should be detected. Then write:

"fastboot oem unlock XXXXXXXXXXXXXXXXXXX" )X being the unlock code you got from DC unlocker)

It gives you a warning about warranty etc you have to comply and your bootloader is unlocked. As it warns you on the screen this will do a factory reset.

If you ever want to relock the bootloader put your phone in fastboot mode and type

"fastboot oem relock XXXXXXXXXXXXXXXXXX" the bootloader will be relocked but as far as we know it's detectable that it was unlocked before.

Hope this helps, cheers

Great to hear that I works!

Are you planning to flash twrp and root it?

Thanks! I just unlocked my bootloader. It didn't work at first but this was because I had forgotten to enable OEM unlock in the settings: https://www.dc-unlocker.com/enable-oem-unlock

I've tried to unlock my P9 using the DC-Unlocker method but it's just saying "FAILED (remote: password wrong)"

Any ideas?

Do you get that in the DC unlocker or when you actually type the unlock command in fastboot? DC unlocker is just for reading the bootloader code not the actual unlocking. If that makes sense. ;)
Also don't forget to "enable OEM unlock" in the dev settings.

I got the codes from DC unlocker, it's the response from fastboot oem unlock <code>. DC unlocker gave me four codes, I tried all of them. OEM Unlock is enabled in settings.

I have read elsewhere that the O2 handsets are bootloader locked, but mine came from the carphone warehouse, who usually send out carrier-free handsets (thus not O2 specific). Unfortunately I don't have a microsim from another network to test this, though there doesn't seem to be any O2 branding or apps.


EDIT: I've discovered the problem, I clicked "Read unlock codes" rather than "Read bootloader code" so the codes were obviously incorrect.

DC unlocker doesn't actually unlock the bootloader, it's just an alternate way to get your specific unlock code. The actual unlocking is done with a command line.
I know it doesn't unlock it and only provides an unlock code but on other huawei phones it can relock the bootloader and leave the status locked instead of relocked.

I've searched for that myself and found a post where someone said DC unlocker can relock the bootloader leaving the status "locked" instead of "relocked". But no confirmation if that is detectable or not and it was from a different device, so no guarantees it will work for the P9... So I guess we don't have a definitive answer how this affects your warranty and it may very well depend on the country you live in, as it usually does with warranty issues.

The official Huawei page states the following (link):

"Huawei will record your unlock request information; for software and hardware failures arising as a result of unlocking the bootloader, Huawei repair centers can provide repair services charged at the standard rate for repair work outside the scope of the warranty."

The way I interpret this it means that you only lose warranty if the damage is directly related to something you did by having the bootloader unlocked. If you have an unlocked bootloader and the camera module dies within the warranty period you should be fine unless they can prove that it died because of something you flashed through the unlocked bootloader. But as I said I think this is handled case by case and depends on your local warranty law.

I have an o2 P( bought in o2 store, used DC unlocker after some faffing with installing hisuite before DC unlocker would recognise my phone.

Got the unlock code unlocked bootloader, and restored 'most' of my data via the hisuite backup feature

I'm not doing anything else with it until I have all relevant files to recover from a sketchy flash or whatnot

I think this might be redundant, yesterday I contacted Huawei through their customer support form on their international page with my IMEI and S/No, and about 10hrs later got my bootloader unlock code with all the usual warnings about the warranty. I'm currently at work so I can't yet confirm if the code works or not but will update this post in a few hrs when I get home.
I was genuinely surprised that the person who contacted me via email was actually a finnish customer service agent, not some google translate-bot or anything.
My device is EVA-L09 and I live in Finland.

    The issue is that this service wasn't/isn't available in Europe. Or at least it was like this a few weeks ago when I tried to get my unlock code from that website.

    And, but this is speculation, it could be helpful in case of warranty, that Huawei didn't provide the unlock code themselves.

    I managed today to get my bootloader unlock code via that website for my P9 (EVA-L09) bought from UK (SIM free from Carphone Warehouse).
