Yesterday I unlocked my bootloader. With the unlocking offline bootloader will follow a reset off the phone. Niente i have a problem: after the reset the FRP option return locked and i can't unlock It in anticipo ways (from developer option is gray). Now i can't flash anything from adb with also the bootloader unlocked.
EDIT:

Did you only unlock your bootloader? Or have you rooted your phone too?

you need to return to marshmallow firmware probably its B136 for you.
1.Flash Rollback Package via dload.
2.Flash B136 firmware via dload.
3.Boot up your phone an check if FRP status is LOCKED. (It need to stay locked)
4.Update to B182 via OTA.
5.Update to Nougat via ota or via dload.
6.Unlock Bootloader
7.Install TWRP https://forum.xda-developers.com/p9/development/twrp-t3565703
8.Flash SuperUser https://forum.xda-developers.com/p9/development/root-supersu-2-81-emui-5-t3612258
Basically its this guide: https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
But this guide will change your OEMINFO (debrand to EU version C432) but this is not bad for future updates.
But this guide is for EVA-L09.

You messed something up while updating.
you need to return to marshmallow firmware probably its B136 for you.
you need to do this because this firmware will revert your bootloader to locked.
1.Flash Rollback Package via dload.
2.Flash B136 firmware via dload.

Hi, first time posting here, forgive me if I'm doing something wrong...
I flashed Nougat beta (L19C432B322), regretted it, and now wanting to go back to EMUI 4.1.1 (before flashing, I was on L19C20B150). Trying to follow the steps for the Huawei official rollback package, but problem is I can't even get the intermediate package (C900B300) to work through dload method... update always fails at 5%.
I am unable to relock my bootloader using the SRK tool. The error I get is "remote: root type is risk".
My phone has never been rooted.
Any help would be greatly appreciated!!
Edit: Tried to flash L19C636B168 full rom using dload method. Now bootloader is locked, but no rom is installed, booting always gives erecovery. Unable to flash any recovery via fastboot.
hello am on c432b361 rooted i want to get back everything to stock what i should do
You must have recovery stock first and your sd card have DLOAD ( update.app) rom .

i flash stock recovery.img of my current version ?
You can try this.
https://www.guidebeats.com/2016/11/26/downgrade-huawei-p9-nougat-marshmallow/
You have to flash the stock recovery for b361, and then relock the bl. You can achieve only the relocked state. To official, locked bl, you have to roll back to b182, or any other marshmallow rom, and then update to nougat.
How can I install the OTA updates on P10 after root? I root it using TWRP and SuperSu. I believe I need to install a stock recovery, where can I get a stock recovery? Also will installing a stock recovery erase my data?

A rooted phone cannot receive OTA update.
I did it this way (on my P10 Lite):
1- Unroot using SuperSU and do not choose to recover stock boot and recovery image when asked, phone will reboot
2- Now download the OTA update using HiSuite and 2 zip files will be saved on your computer.
3- Extract the bigger file (should be called Update.zip or something like that) and you will then see a file called UPDATE.APP file which is like 3GB or so.
4- Now use Huawei Update extractor from here (https://forum.xda-developers.com/showthread.php?t=2433454) to extract the first Recovery.img from it (there could be 2, just extract the first one).
5- Now reboot into bootloader and flash this recovery image and then reboot into system again.
6- If everything is working fine, reboot into bootloader again and relock your bootloader using "fastboot oem relock (your bootloader unlock code)"
7- This will erase all your data and do a factory reset of your phone so make sure you make a HiSuite backup before doing this.
8- Now you should be able to update normally on your phone.
9- If u want to unlock bootloader again and reroot then you do it the exact same way as you did it the first time.
PS. I am not responsible if you brick your phone while doing this.
Hello,
I have P10 lite rooted and with TWRP recovery.
I have notification with new OTA update (B110), cant apply update? What is the procedure for apply Stock OTA update in unlocked bootloader, rooted and with TWRP recovery installed?
Thanks in advance
:crying: Nothing?
You can't update ota with root and unlocked bootloader.

Thanks, and what do I have to do? How do I revert root and recovery?
Factory reset from recovery?
Use HWOTA Tool for updating. It works very well. You need to download the firmware manually via Huawei Update Finder.
If I have a P9 on Nougat B391, I receive an OTA, am currently rooted on Magisk v14. If I install the OTA anyway? What will happen? I know I will lose root, but will my bootloader be relocked? Am I going to lose any data?
Would like to know what will happen next as I am thinking of installing it. thanks!
there are 2 posible outcomes, maybe 3.
1. update will be successfull and you will lose root, twrp, bootloader can be locked too, but on fastboot it will shown as unlocked, if you cant instal twrp, then you need to unlock bootloader even if there is tuped unlocked.
2. update will fail and you will be back on same build you was.
3. never hapened to me, but are possible, that phone got bricked!

IMO, (2) is most possible utcome. (3) may happen if you force DLOAD and other manual methods.
Better:
1) unroot by Magisk Uninstaller, find the download link in the post https://forum.xda-developers.com/showpost.php?p=74913863&postcount=1
2) flash from TWRP original stock boot img
3) wipe Dalwik and Cache from TWRP
3) flash from fastboot original stock recovery
4) let it make OTA update but select in the System Update settings to use Full (not differential) update - it will not delete your apps and settings
Of course, you will loose root and TWRP but bootloader will remain unlocked and you will not risk bricking the phone.

thanks, this roughly gives me an idea on what would happen and the risks it contains! thanks a lot!

Magisk Uninstaller does not wipe your phone.
However, unlocking or relocking Bootloader (from Fastboot) triggers Factory restore
