So I picked up a nexus 6 that was said to be bricked. It was cheap so I figured what the hell. Anyway it's stuck in fastboot. No matters options it goes back to the fastboot screen. In logs it says "invalid boot image header." device is locked status code 2. What chances do I have of getting this back up and running?

Locked code status 2 = bootloader locked right?
Paperweight.
So there is nothing possible to do? I was under the impression is was almost impossible to hard brick a nexus 6. I guess i was ignorant. lol
the N6 and N9 was when they started having the oem unlock enabler in developer settings menu and without the ability to boot and enable that setting its just as screwed as any other locked phone.
Are you talking about bootloader mode?
Locked bootloader+stock recovery (no TWRP) =bricked.
I've read where others have typed "fastboot erase bootloader" which has removed the bootloader so the phone won't even start.
If you have an unlocked bootloader and TWRP then you can recover from most issues. I've formatted my phone with no OS before. You can adb pull a zip in or flash via OTG. Locking the bootloader with no custom recovery or ROM prevents you from installing anything

I am not responsible if you are dumb dumb and break your phone
This Solution is written in under 10 minutes AND WORKS ONLY AND ONLY FOR STOCK people with no experience stay away
This is not a comprehensive solution, if you don't know what you're doing then don't do it!
This solution might work for all huawei phones where:
1. The Oem-unlock is greyed out and NOT activated in Developer Options
2 .Bootloader is unlocked & FRP is locked.
3. You are on !!! STOCK !!!
Problem case:
Huawei P9 lite VNS-L31 on B380
Bootloader unlocked.
FRP Locked.
Fastboot commands fail with
Code:
FAILED (remote: Command not allowed)
except
Code:
fastboot oem get-bootinfo
and
Code:
fastboot devices
Solution:
Have ready your Unlock bootloader code from Huawei
Factory Reset your device. (Factory Reset implies removing Fingerprints and standard Factory Reset)
Reboot to fastboot ,in fastboot you should see:
Phone: unlocked
FRP: locked
Re-lock your bootloader and factory reset ( it will do it automatically)
Code:
fastboot oem relock *Here Huawei Code*
Reboot normally, skip everything
Activate Developer Options
Activate OEM unlocking from Dev Options
Reboot fastboot, now you should see:
Phone: locked
FRP: unlocked
Unlock bootloader again, it will factory reset again
Code:
fastboot oem unlock *Here Huawei Code*
Skip everything again
Reboot again to fastboot and flash recovery, now you will see:
Phone: unlocked
FRP: unlocked
Code:
fastboot flash recovery *imagename*
The OEM Unlock option now is greyed out and ACTIVE
Sucess!After a few hours of debugging and searching for answers I finally managed to flash TWRP, hope this helps.

i have situation:
Phone : Relocked
FRP: Lock
any idea? im stuck in Bootloader.
Thank you very much! I spent many hours looking for a solution to this problem!
Your solution is incredible! Can I share your steps in Spanish for more people? I live in Mexico and I know more people with this problem. And of course I give you the credits for this magnificent solution. I'm sorry for my English, I know I write badly in this language
I have strange problem... I have "Phone unlocked, frp lock". But on my P9 Lite only fastboot mode works.
Rrecovery mode (vol+ i power) or download mode (vol+, vol-, power) are not responding - phone reboots always to Huawei logo.
Any way to fix that?
My phone its f***
What i do
Honor 7x

I have a solution for you both.
I mistakenly followed the instructions above but made the mistake of not skipping everything. I got the message "Data partition corrupted do you want to format the partition" or something similar, DO NOT FORMAT ANYTHING, it should boot up normaly. I'm a bit rusty in my rooting ways u_u
Now, I got exactly the same situation as you both "Relocked" and "FRP Locked". I was able to get into the eRecovery and this is way to restore your phone.
1.- You need to get the Huawei Firmware Finder (Team MT) (https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146)
2.- Unzip it and run FirmwareFinderRewrite.exe
3.- Go to the tab that says Common Base
4.- Search for the update that you know it works in my case was VNS-L31C432B388 (I tried to use VNS-L31C432B404 but its still "not active" whatever that means). Look for the FullOTA and copy the change log address (in my case: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1258/g104/v91282/f1/full/changelog.xml)
5.- In the icons above the Tabs pres on the cloud with a page infront, the tooltip should say Proxy
6.- Copy the changelog addres in the section Firmware for install and press Set.
7.- Press Register for Update
8.- Follow the instructions bellow this (Change your DNS temporarily)
9.- In your phone go to the eRecovery.
10.- Connect to WLAN and it should find a package.
10a.- In case it doesn't find it, go back to step 4. You probably got 2 packages with the same name. I do not enterily understand the differences but I assume one is for one region and the other for other region.
11.- Wait until it restores and be happy.
If you can not change the DNS in you router, as it was my case. You can set a hotspot with your laptop/desktop and change the DNS there but you still need and active internet conection.
I connected my cellphone to my laptop via WLAN and my laptop to the router via Ethernet which provides internet. I change both DNS's for both connections.

Did you guys unlock your bootloader prior to having this situation? aka did you start with
Phone unlocked.
FRP locked.
My solution is for this situation ^ and this situation only, not for any other case.
One other thing it springs right now in my mind is, did you factory reset and delete the fingerprints ? As this might be related...

That's called a soft brick and have you tried eRecovery?
You need to go back to stock using a stock firmware which you have to find on the internet, then make a folder on your SDCard called DLOAD and put it in there, then press all three buttons and the eRecovery should boot up and detect the stock firmware.
EDIT: The guys that got stuck didn't read the part where I said VNS-L31 On B380 and did this having a custom ROM. How I know this? I've also followed my own guide and in the moment you relock your bootloader you will NOT be able to boot into your ROM anymore and you will boot to e-recovery
(which doesn't give too many options), if you were on Nougat or even on Marshmallow (skip the rollback part? )follow the rollback tutorial from N to MM from this Forum Section to get back to stock C432B160/1 , if you can't find the link just PM me
Again, I have VNS-L31 and I'm talking only from what I did, I don't know anything about your device
Man it's not working for me to relock the bootloader. its the same result. what can i do?
really need your help sir

If you have this situation : phone Relocked --> its mean that the phone has been unlocked before and then relocked
If you have this situation : phone locked --> its mean that the phone has never been unlocked before
it's a security from huawei to know if the phone still have a warranty
I have the same situation : phone relocked and frp lock (P20 lite with ANE-LX1 C652 )
because i relocked the bootloader without leaving the frp unlocked.
When you relock the bootloader ( relock phone) the phone will do an automatic factory reset, and if he fail with, you can't unlock bootloader again because of the frp lock, and you can not unlock frp from developper option because the phone won't start.
I tried the Firmware Finder solution to get erecovery working with DNS, i found an update for (ANE-LX1 C652 not FullOTA) and i register it for download, the phone start downloading, after finish downloading i get a fail install error.
i tried register many version C432 C185 ..... but the erecovery is not reconizing them i think that i need a FullOTA for my ANE-LX1 C652.
Installing update with sdcard dload, always fail .

Hello dear,
so i have unlocked my phone and this was the beginning of the problems, I had to deal with samsung phones before but the huawei was very sensitive, so i got into a problem and broke the phone system, which had taken the phone to an expert and had restored the stock phone system n it was good to roll back ,phone to work at least, he tells me that he did relock the bootloader but the message of warning still appears everytime i booted up ,
now ive the same problem as u have, and i noticed that the adb commands works only when the phone is on system ,either when i enter the FASTBOOT MODE ,ADB commands do not work anymore ,even the gray OEM unlocking,, and now i do not know if this solution works with me or not ,if i can get rid the warning message?? i dont need that silly unlocking anymore
ِِCan u advise me PLEASE !!!!

The warning will always appear as long as the Bootloader is unlocked. read the first 3 conditions . If you are on stock and can boot on stock, delete fingerprints and any PINs and Google accounts, then Factory Reset and this should set you to FPR Unlocked, BL Unlocked. Here just lock the bootloader back and then reboot normally and use the device as you normally do, the moment you add your Google Account and/or Fingerprint the FRP will lock back. If you want to continue flashing custom ROMs etc. follow the tutorial but read all the comments (relevant ones) before you do it.
This solution might work for all huawei phones where:
1. The Oem-unlock is greyed out and NOT activated in Settings -> Developer Options
2 .Bootloader is unlocked & FRP is locked.
3. You are on !!! STOCK !!!

if that applies to you, you can try my tutorial, otherwise I have no other suggestion for you, I quit tampering with my Huawei long ago, stock is quite fine for me.

to me puts
PHONE Locked
FRP Lock
phone stuck on recovery mode
Hi,
I have a P9 here I'm was asked to repair. I think it is kind of bricked and I hope some one can help me to unbrick it.
According to the auto dc-unlocker identification:
Found Phone : EVA-L09
Firmware : EVA-L09C432B386
FB LockState: LOCKED
USER LockState: LOCKED
So, bootloader locked and FRP locked. I don't know if the Firmware version above is right. All I know is that some Update.app files were flashed to the state of the phone now and before there where bootloops while the start animation and stuck boot with black screen.
At the moment I can do:
- turn on to see only the first huawei log with "powered by android", then nothing happens
- I can not enter eRecovery or update for Update.app
- I can only enter fastboot
I have the unlock code for the bootloader. I can not commit any fastboot commands (oem unlock, flash, etc) all is blocked with:
FAILED (remote: Command not allowed)
The locked FRP should be the reason for this.
I think OEM-unlock and usb debug from developer section was not enabled as the phone was usable. adb commands like "adb reboot bootloader" fail with
error: device '(null)' not found
fastboot devices shows the device
I have tried to uncharge the battery and then try to enter other modes than fastboot. No luck with that.
Do I have any chance to unbrick it without paying for the dc-unlocker/phoenix?
Can I do something with SRKTool?
If I have to use unlocker,
- do I have to unlock the bootloader?
- should I flash the same firmware that is now on the phone (B386) and where can I find it? (found only 1000 other versions until now)
Hope for answers
I've gone through that before, but ended up using DC-Phoenix to unbrick it when it's FRP and bootloader locked. Cost me about $15. There is a post on how to do this but I'll have to search for it again.
Here is the post I used:
https://forum.xda-developers.com/showpost.php?p=71767614&postcount=7
I guess you enter fastboot by Vol- and Power?
Not sure if the following method could help you with, but you can analyze before you go for dc-phoenix:

So you can not update via dload method? Did you try booting into recovery (not Recovery)? And you can't update with Update.app, you need to flash update.zip and full_update.zip via TWRP or Recovery. What wanted the owner of this phone to do, that he bricked it ?
Thank you all for your answers. Like I tried to describe: I was not able to access any other mode than fastboot.
"was able": I used DC-Phoenix now and it worked just fine.
Little confusing is that in all tutorials, even the on on the DC site, the UI of the tool is different.
But that's now Problem. The current Version is lot easier. Just "Standard Mode", select Update.app (full), Click Update.
The Phone gets flashed with fastboot, DC will restart it to update mode and will flash again. All automatic.
Really easy.
so you paid 15 USD ?

Found the Problem!
The Device say's its unlocked but it wasnt so i unlock it second time and it just reboots after second unlock in to the TWRP.
Maybe it will help someone
You couldn't flash TWRP if you didn't unlock bootloader - and the phone warns you that bootloader is unlocked
If you want to get rid of the warning, you must re-lock bootloader, but it will trigger factory reset
Btw, enable Development options and check if OEM Unlocking is enabled
And in Fastboot, check does it show Bootloader and FRP unlocked
Hello friends, I'm Berat, living in Istanbul, Turkey.
I tried to install TWRP on my device (HUAWEI P9) for root yesterday. I couldn't go further from the Fastboot - ADB method. Although I do one-to-one with source videos from Youtube, I have encountered error messages. The phone is running like stable but I have a few problems with my phone.
1- I want to complete root if i can do that.
2- OEM Unlocking is unclickable now and this is disable now, and of course it can't be changed. :victory:
3- I wanted to go back to the original version but it doesn't work either, OEM Unlocking is same; unclickable. I did enter the Fastboot menu and i saw the last status: Phone - Unlocked / FRP - Locked
How should I proceed? Which one is the easier, ROOT or the original version?
Thank you!

- Which stock Android do you have, Marshmallow, Nougat or Oreo
- Which TWRP are you flashing
EMUI versions are different, each has different organization of partitions (names and sizes, different encryption types).
You must use different port of TWRP for different version of stock Android.
Wrong TWRP may not work or may even cause a brick
For Nougat, instructions are in this thread:
https://forum.xda-developers.com/newreply.php?do=newreply&noquote=1&p=71244945
but a little bit newer version of TWRP for Nougat is in the post #1 here:
https://forum.xda-developers.com/p9/development/rom-huawei-p9-magicrainbow-v4-t3759292
---
For disabled and grayed out OEM Unlocking:
Boot to eRecovery (switch off, connect to charger, press and keep pressing Vol+, press Power).
From eRecovery, choose Download and Install latest firmware and recovery.
Upon installation (before booting to System), choose Factory reset and Clear Cache
You will need to enable again Developer options and OEM unlock (it should not be gray anymore).
If Bootloader will be locked, unlock with the same, previous code
