enable OEM unlock - Disabled setting - Huawei P9 Plus Questions & Answers

Hi, after some attempts to upgrade to N, this is my situation:
The essential setting "enable OEM unlock" is Disabled, not selectable!!
So I'm blocked with any restore / twrp procedure...
What to do?

Here you can note this, is in "gray"

When I'm in fastboot the FRP is Lock (in green)
Someone already solved this?

roll back to M ... this will solve your problem.

I'm managing it via DC-phoenix... but I'm not totally out of troubles...

relock bootloader, only then you can enable oem unlock
tested on Mate 9

Hey!
It's a little tricky, but it worked for me. My device was OEM unlock, but FRP locked and with that I wasn't able to flash any of the files. Fastboot flashing and other normal flashing methods didn't work anymore and even tho DC phoenix says it flashes all the partition it still gives you bootloops afterwards.
Here's what I did:
1) Downloaded the original ROM file for the phone. I.e my phone: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1163/g104/v57187/f1/full/update.zip
2) By using DC phoenix to bypass the FRP lock and flash the TWRP recovery - https://forum.dc-unlocker.com/forum/modems-and-phones/huawei/155916-dc-phoenix , but this is a little tricky. When you select the ROM you want to flash, it starts to extract the files into the folder where DC phoenix is located. Here you want to overwrite the recovery.img with the file from TWRP, before it starts to flash the phone. This is what makes it possible to flash the old rom
3) Now boot up into TWRP and flash the original ROM file - The update.zip file!
This should get you bring you back to Android 6 and you can now disable FRP lock from the menu.
After this, I once again flashed the original firmware again, but with all the default contents for the DATA partition and using the normal flashing method - PWR key + VOL up and VOL down
If you want a more detailed version, please let me know...
Best regards,
Claus

Must i understand that the N is not the update we expected? A lot of issues with the P9 Plus after the "big" update

I have fixed more than 10 phones with dc-phoenix.
You must know how to use.
I didn't fixed them for free though

Hello guys i make update on my Huawei Nova Can L01 C109B100 to emui 5.0.1 anfroid 7 C109B331 and now i have build number NRD90M test-keys everything work perfect except factory reset,themes and update app.I try with Hi suite but not work because not want to connect after did settings corect on option development with usb debug on and oem on.Please give me solutions for fix that,wait your advice,thanks in advance.... i flash with huawei finder wrong firmware and now i need flash the verison good of my firmware but i don't know wich are this firmware,please help me,thanks a lot.I forget tell you that in option development OEM ENABLE BUTTON is invisible and i can't enable....

Hit the 'Restore default settings' button at the bottom of the 'developer options' and it should disable OEM unlock, and you're free to switch it on/off now, at least that's what worked for me....YMMV
It also fixed my issue of USB Debugging disabling itself automatically.

the problem is the security settings...try disabling the pin/password/pattern/finger print totally then see if it is enabled then.

I have honor 8 i unlocked bootloadr when ny phone rebooted on developer option I clicked restore default

P9 Bricked, Bootloader Locked. No TWRP Installed. FML (Send Help)

Think I did the title pretty well, I can only access fastboot (Before you say anything I've already tried this guide:http://forum.xda-developers.com/hua...ow-to-unbrick-huawei-p8-failed-t3260704/page1) all it gets me is the screen to light up (black) that's it. At this point I have no clue how to bring it back, any useful tips or ideas would always be appreciated. Thanks.
EDIT: It would be helpful if anyone knew a way to unlock the bootloader through fastboot
EDIT: nvm unlocked the bootloader through adb
EDIT:Installed TWRP through FASTBOOT
EDIT: Had the future rom downloaded, installed through SD card. DEVICE BOOTS.
EDIT: Tried dload method, went back to square 1 (Device would only backlit screen on boot, bootloader locked) Repeated steps and used the Huawei P9 Updater 2.0 by Hajuuk (Godbless) IT WORKS. Currently on C185B170 will update to B180 and from there to Android N. IF anyone has a similar problem feel free to ask.

Hi, I have problem. I have two Huawei P9. One is L19 and the other is L09.
My L19 is the C900
My L09 I do not remember what it is ... the problem is that it is no system, it only turns on fastboot recovery mode. I've tried combo keys with dload but it does not work or does not recognize. By Hisuite says that the model is not supported. Finally I tried the Firmware Update program by hajuuk https://forum.xda-developers.com/p9-...dater-t3435878 I used several firmwares inside the L09 option but in the middle of the installation it gives error.
I need to find a way to enable the OEM so I can flash boot.img, recovery.img and system.img because I can not flash anything at the momento because it gives the Not Allowed command.
The status is Bootloader locked and FRP locked.
I do not know what to do, I have no ideas.

I think there is not solution for this problem. We have to wait. (I have the same problem but in Al00 running Al19 rom)
How do you check for FRP lock on a Huawei phone just curious.

Okay to unlock the bootloader, go into fastboot and plug in the USB to your computer, then by either using SRK tool or adb you need to flash this command: fastboot oem unlock (insert bootloader code) *don't put brackets* if you are unaware of your bootloader code then I cannot help you, however if you do know it, then once you unlocked the bootloader flash system.img and stuff to see if that works for you

That's weird, OEM unlcok was also switched off in developer options for me, yet this still worked, can you tell me exactly what the error code says?

I've tried some command in fastboot mode but there's always an error: Remote: command not allowed.
I can't do anything with fastboot mode
1. Try to force update with Power Button + Min Vol Button + Max Vol Button, liked you said this isn't working try to do the button combination with the phone connect it to the PC; in my case some times dload din't works after I connected the phone to the computer.
2. Other thing, something happend if you turn of the phone and leave Max Vol Button pressed, you should be entering to eRecovery.
3. Remember that sometimes enter in eRecovery mode requires to the phone be turn off otherwise you can't access to Recovery. So if this is the case follow bullet #2 and them #1.
PD: OFC I'm assuming you already have the dload folder with an compatible version of stock ROM on your SDCARD. If you don't have any version tries this one: https://forum.xda-developers.com/p9...dload-file-p9-eva-l09-b136-t3382818?nocache=1
Hope I helped you, I already bricked twice my P9 corrupting System Table Partitions.

If you did the change of Unlock OEM before the bricked in an previous authorized computer you will still have rights for, otherwise new Android Security features is going to rejected the request.

I have a P9 L09, i have unlocked the bootloader, flashed TWRP recovery, and started flashing some roms. I have succesfully flashed a cyanogenmod, and it booted properly, but when it started it asked me for a password which i did not know, so i google searched and found out that it is a common issue and i need to wipe data from recovery. I tryed that but it did not work it says failed, and nothing works in the wipe advanced section, beside system. And also in the custom recovery it says that the internal storage has 0MB ! I was able to put other custom roms on the SDcard and flash them, they booted but every single one asks for the password.. I then tryed to install stock rom with the dload method, but it crashes and 40% , and i tryied the System Recovery option in HiSuite and it says it is not compatible with my device. Any help would be greatly appreciated! Thank you!

when you say "relock the bootloader via ADB you mean:
adb reboot-bootloader THEN fastboot oem lock (and the code)?

HWOTA working and solved your problem.
just yesterday I made mine. the bootloader was open but the frp was closed.
the HWOTA has solved it nicely. now vtr-L29C432B185 firmware is up.
Unfortunately, this disadvantage is the low level format after the bootloader has been re-opened as the firmware closes.

I have the same issue, but i can´t turn on my phone to unlock OEM.
What can i do?

Did you find any solution?
I have a Huawei P10 plus (VKY-L29). Tried all methods to bypass FRP to no success.
- Talkback (V7.3 - Therefore no luck)
- Emergency dialler (*#*#6130#*#*) not picking up as well as other dial codes in emergency dial
- Erecovery (cannot find any recovery files)
- Fastboot mode (phone restarts to Welcome screen soonest booted)
- Wifi (Connect to first Wifi and then forget this network and connect again to 2nd Wifi entering some manual details on the host/proxy and then connect again to force the phone to come up with the error message in order to access help) no luck
Am I missing something? has anyone had success already regarding the Huawei P10 Plus FRP bypass????

impossible to restore to stock firmware

Hello everybody,
I have a P9 that mounted twrp and magisk.
Needing safetynet pass, i decided to make a factory reset of my phone and to try again the rooting. Unfortunately i discover that Huawei had blocked the bootloader generator of codes and now i have a phone, that is switching ON, but missing a lot of apps (calculator, clock, recording voice, etc...).
Also commands like *#*#2845679#*#* to try update from there not working (not appears the hidden menu)
I tried to restore (finding my exact firmware) via dload but everytime i get error at 5%. Via OTA update same errors.. Now i have the phone in Bootloader LOCKED.
Can someone helps me to install again the full stock firmware in my phone. Thank you so much

Before Factory resetting you had to uninstall Magisk and to flash stock Recovery...
You can't apply DLOAD to builds that are not FulOTA_MF_PV (and most new builds are no more PV)...
Since you prevoously had TWRP, you did have Bootloader unlocked - just use the same code (you had to save it when you obtained it from Huawei) and unlock the Bootloader again.
If you didn't save Bootloader, this time you will have to buy 4 Euros credit and get it from DC-unlocker

I have no more the bootloader code, i never save it. I think so, buying it and after doing everything. Thank you

If you are on Nougat, when you buy the code and unlock Bootloader, then flash TWRP and use HWOTA method to recover stock ROM
https://forum.xda-developers.com/p9/development/rom-huawei-p9-magicrainbow-v4-t3759292/
If you never ever want to root, then you could try to save 4 Euros (not unlocking Bootlader) and
a) Settings / Advanced Settoings / Backup and Reset / Factory reset and accept to Wipe Inetrnal memory
b) Boot to EMUI Recovery (switch off, boot by pressing Vol+ and Pow) and choose Factory reset
But not sure would it be able completely restore stock ROM (apps you are missing).
Also c) Switch off, connect by USB to charger, boot by Vol+ and Power, it should boot to Huawei eRecovery. Then download (over WiFi) and reinstall stock.
But I will prefer getting Bootloader code and then using HWOTA.
When you have unlocked Bootloader, if things go wrong, you have more options to unbrick the phone if it becomes necessary

[GUIDE] Downgrading Huawei P Smart, Unlocking bootloader and installing TWRP

Downgrading Huawei P Smart, Unlocking bootloader and installing TWRP
Hello! In this tutorial i will show how you can, downgrade you phone, installing TWRP + root!
Why you need downgrade? You need to downgrade security patch to read bootloader unlock code.
Lets start!
Note: This method will cost 4euro/dollar. You need buy 4 credits to DC unlocker. Just google for it.
Note 2: Backup your important files. You need reset your phone twice.
Note 3: Im not resposible if you success to brick your phone. I can always help, if you have Discord you can contact ScaryG#8540/B] or just ask in comments
Note 4: Twrp wont work with custom roms :/
Also if something missing from tutorial, please tell down. I will fix them as soon as possible:good:
Part 1. Downgrading
You need 16 GB SD card. First format it to extFat. Then download firmware from androidhost.ru, i used FIG-LX1 8.0.0.128A(C432) Download it. ( Links below! ) Then find dload folder from zip and extract into SD card (Remember to format SD Card into extFat)
Wait until it extracts. Now put your SD Card into your phone. Call *#*#2846579#*#*, locate for software upgrade and press SDCard Upgrade button. Now your phone is installing the update. Wait until installs. After install, you should get bootloop. In this part Press Volume UP + Power button, go to recovery and do factory reset. Now wait until boots. Go to settings -> about, and you should see version (128A). Boom! You have done downgrade...
Part 2. Unlocking Bootloader
Okay. Now get DC Unlocker ready, select auto detect Huawei Phones. Now go to again call to *#*#2846579#*#* and enable manufacturer mode. Try auto detect. It should detect your phone. Now simply, press the Unlock button. You should get your bootloader code, take it up. Enable developer options on your phone, go to USB Debugging and turn it on, also turn OEM Unlocking on. Then open cmd and type cd (same path as dc unlocker folder). Type adb devices It should start ADB daemon. Check your phone, you should get ADB trust popup, Allow it! Then check again adb devices, your device should be there. Now type adb reboot bootloader After it type: fastboot oem unlock (your key) ex. fastboot oem unlock 12345678. Check your phone, and press yes. Yeet! Your bootloader is now unlocked! Type fastboot reboot to reboot! Now goes kinda easy part!
Part 3. Installing TWRP
Download TWRP for Huawei P Smart. I put links below.
Move file to same folder as DC Unlocker and rename it to recovery.img
Anyways, your phone should be resetted again...
Go again enable developer options + enabling USB Debugging. Then again confirm...
Now do again adb reboot bootloader now type fastboot flash recovery_ramdisk recovery.img Now it should be flashed. Get into TWRP by pressing Power button and Volume up. Now you can root and flash zips!
Thats it, i hope it helped :good:

You need download the update, then extract all from zip. Not only update app.

Hi ! Hope you saved the unlock code somewhere
If yes, you can upgrade any way you want. Just redo 'fastboot oem unlock xxxxx' after successful upgrade. (Worked for me on EMUI 9.0.1.115)
It will unlock and wipe again..
As for me, this is the point I'm stuck at :
- latest EMUI FIG-LX1 9.0.1.120 (C432)
- bootloader unlocked
- can flash twrp, allow it to prevent being overriden, then flash Magisk 19.3 without error in the log.
After that, phone boots ok but Magisk Manager says 'not installed' and TWRP must be reflashed again.
Anyone can help further ? I've read about patched boot images to be flashed with fastboot. Are they just Magisk patched or some additional security level hacking required ?
Thanks XDA
Hi.
Just FYI, afters hours, I managed to finish the procedure and restore full root/magisk under latest EMUI 9.1.0.120 (E)
I had to use magisk uninstaller under TWRP, then reflashed Magisk 19.3
Now everything sticks :
- TWRP 3.2.0_1
- Root access
- Magisk is detected as installed and running
I mainly use "systemless hosts" with Adaway and it's OK.
Did not test any other module yet.
Hi,

Just unlock bootloader with same way on emui 9.
Hey there! I've tried downgrading but i instantly get the message "Software install failed." before it even starts to install. Any ideas?
Can't downgrade from android 9.1, everytime said Software install failed
Thanks for the tutorial. I was able to install the older EMUI 8.0 version and unlock the bootloader of a FIG-LX1 (C432). Two tips:
I was able to use a uSD formatted in FAT32, I did not need to format it again using ExtFAT
When using the DC Huawei Bootloader Codes app from PlayStore to buy the credits, select Android 7 to get charged for just 4 credits, otherwise it will try to charge for a 3-day license
Make sure the phone has 8.0.0.128A or older, and DC Unlocker 2 recognizes the phone properly before buying anything (if it is not the correct version, it will tell you to use the test/probe point method)

I can only thank you hugely for this clear concise instruction. Well worth £3.41 to DC Unlocker developers! Finally an unlocked bootloader on my wifes phone. I'm a definite Xiaomi phone fan compared to the ridiculous hoops Huawei make people go thru with their locked down phones. Gave up with Samsung years back too for the same reason. Cheers
Hello , I have model FIG LX1 and I want to flash roms. I need to follow this guide ?
And basically I have to pay ? What the hell

Huawei P9 - Failed TWRP attempt

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
