Hi,
I have a problem with my Huawei P9 that I bought used. I realized during the reset that the Google account is blocked, but I no longer have the number of the person to whom I bought the phone.

I tried the videos to bypass frp, but I do not have access to the menu "help & feedback" (3:20 in the video)
https://www.youtube.com/watch?v=qSLJchfjQkM

I think that rom includes a new patch security :crying:

I'm looking for a way to install TWRP to change the rom and go Cyanogen to bypass FRP or attempt a downgrade of the official rom.

The concern is that my computer is not detecting the phone. A warning message tells me that the usb device is not recognized. I think it's a security of Huawei not to have a user use adb or other commands to change rom.

I think the bootloader is lock.

Do you know a way to bypass frp on huawei phones with the latest security update or is there a way to change rom with a bootloader lock phone and no possibility to go into the settings to allow the enable usb debbugging (since I'm stuck when I start the phone)

Thanks :)

How could he flash with the locked FRP?!

Btw, once you are (already) on AL10 Oreo, you don't have OEM Unlock option in Developers menu.
But to rebrand by HWOTA7, you needed FRP and Bootloader unlocked.

Moreover, even on AL10, if you boot to Fastboot you would see that FRP is unlocked.

And there is an attribute in one of the system XML files, if you enable it (root required for editing) you will unleash the previously hidden OEM Unlock option in Developers menu (ie, then you would have OEM unlock option in Developers menu just like in Nougat)

Look at this thread
https://forum.xda-developers.com/p9/help/bought-phone-ebay-registration-wizard-t3840803

Similar case with the second-hand P9, where previous owner did not remove his Google account before removing his SIM card and giving the phone.

Read post #1 and then post #7 till the end - solution was DC Unlocker/Phoenix with the price of 15 Euros credits.

PS:
- When doing Factory Reset you should either had original SIM from the previous owner, or he had to remove himself his Google account(s) from the phone

This way phone reacts as if it was stolen (with the SIM card protected by PIN, and when the thief then removes original SIM and tries to bypass Google and FRP protection)

Thank you everyone for your reply ! :)

I do not understand how this paid service will solve the problem and not me (with all the knowledge available to xda volunteers)
Does DC Unlocker have privilege to unlock the bootloader with Huawei?

Apparently their tool knows a back-door hook into the Bootloader

It works

Great !
The software is easy to use and i pay 15€ for unlock my Huawei P9.
I click on the unlocking button after putting my phone in fastboot mode and immediately, the phone reboot and makes a factory reset low level.
I think DC unlocker find system flaw that they alone know.
I do not know which version of android had the phone and which version of the security level but for this rom the security level of android is February 1, 2017 and the android version is 7.0 with EMUI 5.0.
Knowing that I could not bypass with 2018 methods found on youtube or xda, the phone downgraded to another version of android.

I think that their software finds a flaw for downgrade with the bootloader lock and that remove the frp protection

Thank you zgfg :D

Thank you for confirming and reporting your experience, it might be useful for somebody else (in that another thread I gave you link in the previous posts, it also worked for another user)

Btw, now when you opened FRP and Bootloader, did you upgrade to the relevant latest Nougat, or do you consider going for AL10 Oreo?

This is my second phone and I am looking to stay on a stable system and get used to EMIU. If i like EMIU, it will become my main smartphone.
I will make the OTA update that Huawei offers and stay on Nougat :)

Ofc. I actually also like EMUI
Btw, EVA-AL10c00 b535/b539 is also EMUI

Stock firmware already contains international languages, just few patches are needed to get
Mob NW working
Playstore installed

and then can optionally come
Magisk root
Face unlock (n/a on Nougat)

Open Kirin Treble ROMs O and P (that can be installed over) are for those who want AOSP based experience
