DCUnlocker does not work !

What can I do ?
http://www.noelshack.com/2016-32-1470686320-capture.png
And even through the Huawei site I receive the code does not work.

For the software to work, you must setup the phone to be in manufacturer mode. See https://www.dc-unlocker.com/huawei-android-hisilicon-unlock-guide. Once you do that and use dc-unlocker software, then you will see the phone plus all options (those that appear presently disabled) will be enabled.

I did , but that does not change when I reboot

hmmm....you don't need to reboot....Just type *#*#2846579#*#*, select "Project Menu", "Background settings", "USB ports settings", "Manufacture mode". Then connect phone to PC and start dc-unlocker. When you search for devices, you will see your P9 with the options on the top right enabled.

I unlocked my phone and then de-branded it. I used dc-unlocker to unlock bootloader by purchasing needed credits.

I got the code! but it does not work

I'll teach him to fly, this system code makes me crazy

Ok. I don't know how or where you got the code from but assume it is not right. I say this as I used my code against the phone on a couple of occasions (change a c900 to a c432 version, etc) without any issue. Assuming it is not right, I suggest you buy credits on dc-unlocker direct. I think it is 4 euros or something like that. You just select the unlock option and it does it all for you.

I took the bootloader code and it does not work
http://www.noelshack.com/2016-32-1470691341-capture.png

Ok. Did you enable the property in Settings > Developer Options > Enable OEM Unlock ?

the code does not work, then I have had with DC Unlocker
I still like what solution?

I have 2 solutions:
1- You can try disabling "phone finder" app and try unlocking after. Some say this is the cause of making the bootloader being unable to unlock.
2- If the first solution didn't work, you can try flashing an older firmware on your phone.
I hope one of these work for you.

I can flash a firmware without unlocking the bootloader ?
I do not apply ' phone finder ' in my application ...

You don't need an unlocked bootloader to flash a firmware using the 3 button method. Try to flash an older firmware and then try to unlock your bootloader again.

Thank you ca I'll try tonight! And it is better that I get the code via the parameter devleopeur or something?

To flash a firmware, download it, copy it on a /dload folder of an external sdcard and then boot your phone holding both volume buttons and power button. About SRK tool just look at dedicated thread. Is really simple to use it.

You advise me as what rom ?

I don't know what you want to do by unlocking the bootloader, but try using this SRK Tool. This should do the job as it also allows generation of the bootloader code plus unlock.

Is it possible to re-lock bootloader after official unlock?

I'm doing some research before I commit to unlocking my bootloader, and I can't find anything definitive on whether or not it's possible to re-lock after unlocking with the official tool. I have experience unlocking and re-locking bootloaders, flashing custom recoveries/ROMs/kernels etc but only with Nexus and Samsung phones, so I just want to make sure I'm clear on how Nokia's setup differs (If at all). Would also be interested to find out if Nokia will still offer me OTA's with unlocked bootloader.
Thanks for any help, and feel free to move or close the thread if it matches another one that I've missed.

Nokia says that relooking isn't possible. Is there anybody who tried the command 'fastboot oem relock'?

And why says this text please lock ? the bootloader, if it is not possible?

Since I also unlocked critical, I ran: fastboot oem lock_critical and then fastboot oem lock
Phone will factory reset both times.

Has anyone tried the re-lock with a custom kernel/ROM?

No, and nobody should do it. It will brick your device.
The point of a locked bootloader is to prevent unofficial software from running, and the point of unlocking it is to make that possible. So relocking the bootloader with unofficial software installed will make the phone think that the software got corrupted and rightfully lock down the device.

Basically anyone should be able to do it and it shouldn't brick your device, as per Google's bootloader recommendations. However, manufacturers decide to cripple bootloaders not to support it in the verified boot chain (where kernel verification can be explicitly made against a custom root of trust set after the device has left the factory i.e. set by the user, instead of the original root of trust). As far as I know, only Pixel devices implement this, and can be achieved by issuing the command:
Code:
fastboot flash avb_custom_key <key_blob>
I'm sure there are lots of advanced users/modders that can find this feature beneficial (if implemented by the device vendors).

is there any other way to fix my phone??
Code:
fastboot flash avb_custom_key <key_blob>
how to use this code? any specific key_blob for nokia 8 or is it supported on this phone?
help me guys ;(
Edit:
After so many tries, I went to service centre and they fixed the phone in few mins :highfive::silly:

lol my device was under warranty so I got it fixed for free

I can assume that, in service centers, they are able to reflash the entire firmware including the (secondary) bootloader. They would probably boot the device into EDL mode, and flash it with stock firmware, with a properly signed Qualcomm EDL programmer, and use Qualcomm's QFIL tool to do this.

Fastboot is works
Bootloader locked
eRecovery works
Stock recovery works
I have a my phone bootloader key
But DC Phoenix not flash any update.app or board.dgtks file (DC gives evrytime ERROR... device not supported, flashing incomplet). Flashing stops befor DC phoenix can open backdoor.
In fastboot works only one command, that is FASTBOOT DEVICES, and result is 123456789ABCDEF
I can*t flash nothing in fastboot vommand line: gives me error for example:
FASTBOOT FLASH OEMINFO OEMINFO.IMG
sending `oeminfo` 378kb...
OKAY
Writing `oeminfo`...
FAILED remote: Command not allowed
Any fastboot command ends with that error
eRecovery get errors after try flash WIFI DNS firmware finder.
Device lost all: oeminfo, vendor, IMEI, model
And only founded information by DC/HCU/fastboot is device name 0123456789ABCDEF
What i can to do to fix that?
Thanks

Yes, you must flash the board with DC Phoenix. And if you don't have the nvme backup, then avoid flashing that when you flash the board.
Follow the latest posts from that thread, to understand how to put it in COM1 with the test point.

That COM1 was kind of "fake" and Phoenix couldn't flash anything. With test point it should work just fine.

Did you tryed a working dload image for your model in dload-firmware mode?
-with a build GREATER than the one you previously were on with your ALP ?
I don't know if your cust was blanked like boardnumber and imeis in your previous doing with your phone and what it does imply for dload images which are normally not cross cust compatible...

If bootloader is locked that's the reason why you can't flash. You'd have to unlock it.
Also, oeminfo can not be flashed with fastboot with "regular" unlock.

Well, it's fastboot oem unlock UNLOCK_CODE, but if you tried that already it won't work.
If your oeminfo is corrupt that might be why, as it reads imei and SN from oeminfo to calculate unlock code.

return in warranty if bootloader locked

the only fix is to send it to huawei service what ever bootloader locked or unlocked

Temp P20 BL Unlock, What can i do with it?

I followed this guide

https://forum.xda-developers.com/showpost.php?p=79383551&postcount=18
It actually does work after bricking the device i was able to restore it by flashing the internals of the update.app. Im able to flash ANYTHING which you can with an unlocked bootloader, after you reset you lose the temp unlock obviously. Im wondering what can i actually do with being able to do this?, Because it relocks after a reboot is it useless? I have tried to root but i imagine the recovery_ramdisk file restores itself to its original state after reboot?
Any help or tips would be nice, thank you!.

No I'd say it's not useless. Will check it out..
If you can get TWRP can you flash anything? Custom ROM? Try AOSIP, can you flash magisk?
Try some things, what's possible?

Sadly nothing so far!, TWRP will install but won't show up after the reboot, maybe because the bootloader locks back?. I was able to unbrick the device and downgrade and upgrade etc, thats about it
