how to get back to stock? - Huawei P9 Questions & Answers

i want to get the phone back to stock.. it is rooted and twrp recovery.. but i cant get the phone to fix this itself..
can somebody tell me what to do, is it just to flash the recovery and factory reset? anybody have the files and steps needed?
EVA-L09

i need to know too....i try with dload-folder update, it's reset to stock, but when i install supersu 2.78 in twpr, i get bootloop, so i install ncs-rom back....

Did you try this?

Find the firmware you need (by the model of your phone). It will be a .zip file. Extract the file from that .zip on your PC, you will find a file named "update.app", who must to be copied into a folder on the sd-card named "dload". Turn off the phone, wait few seconds, press all 3 buttons (power, vol-up and vol-down) until the image with the android robo will appear. Release the buttons and let the phone to do the job ... Instead of pressing all the 3 buttons, you can try dial
*#*#2846579#*#*
select "Software Upgrade" - "SDCard Upgrade".

You need to flash stock recovery before doing this.

i just do this with twpr and it's work,,,,update install itself stock-recovery..

Not with mine, if twrp is present it boots to twrp and nothing. Had to install stock recovery.

[Q] Cant into recovery & Stuck in Bootloop on unlocked device

I want to flash a CM11 into my tablet, so I unlocked bootloader.(Devise's Build Number: Version V10.26.1.18 )
------> I flashed a CWMrecovery 6.0.4.5 into it .
----- > I reboot to bootloader can't get into recovery, so i select a full wipe in bootloader.
------>Tablet stucked in boot screen. I can't flash anything into it, because i can't get into bootloader & recovery(Even use Vol - &Power Button).
How can i get into bootloader again?
Or recovery?
Or flash a Offical rom back into it without recovery?
Unfortunately wiping from the boot loader on a custom recovery can hard brick the device. 6.0.4.5 is very old, the latest cwm is 6.0.5.1.
Try flashing that from the boot loader.
But how can get into bootloader?
I have try press Vol Down & Power button, it didn't work,and my computer said “< waiting for device >“。
Is it possible to connect with PC once more?
Try the SD card stock update method
see if this works... this is the best method I have seen to recover the TF701T. Try the manual SD card update method by downloading the correct firmware for your device first from Asus. then see if there is a zip inside of a zip file if so unpack it once. Rename the zip file to T4_SDUPDATE.zip and put the zip firmware file on the root of the SD card and power on or restart your device. it should detect a firmware update. this is the procedure I used when I bought my tablet.
I updated my tablet to the latest stock firmware before I UNLOCKED and installed the latest CWM recovery. Then I booted into stock and shut down then did a full backup of stock, then I flashed custom ROM and latest SuperSU... if you find this helpful, please click the Thanks button below!

Sorry mate, the only way to get into the bootloader is with Power and Vol Down. If that does not work you cannot access fastboot, you cannot access recovery and the tablet is a brick. Only a new mainboard can revive it.
I am not sure, if bootloader located in SPI flash it is not very difficult to reprogram it with external programmer.

[Q] can´t flash update.app please help

please help, i can´t flash an original firmware with original recovery.

Try to put the update.zip in the dload folder. Then go to local update.
That did the trick for me.
By the way: you enter recovery by: volume + and power. Hold the power button untill the phone vibrates. Then release the power button but hold the volume +
Same issue. I rooted and installed TWRP, bootloader is unlocked. My version is L10. I can't seem to get any rom to work though. Tried updating to emui 3.0. boot loop. Tried flashing myrom 3.3. boot loop. Tried fastboot flashing recovery to stock 609 recovery, now recovery won't load. flash back to twrp, and it works. I am going to try this update.zip thing, but please let me know if there is a way to safely get to a new rom. Stuck with emui 2.3 or whatever, is very annoying. b127, and it won't download an ota, says it's already latest version

brick ...

Hello, sorry advanced my English is not good I have a problem with my L-10 ... its brick .. I don't have access recovery and I have wiped the room . thanks you . (I am french).
Enter fastboot mode by holding "Volume down" & " Power" buttons while your cable is connected to the computer.
Make sure that the USB drivers for P7 L-10 are installed by installing HiSuite from official Huawei website.
Now download ADB and fastboot here https://www.androidfilehost.com/?fid=24521665358595410
Now you'll need 2 more things - Official P7-L10 ROM & Huawei update extractor which you can download here http://forum.xda-developers.com/attachment.php?attachmentid=3262545
Once you have all of those we can start the fun with the command line
Once you're in fastboot mode you'll have either green LOCKED screen or red UNLOCKED screen. You need to have a red screen in order to send commands to your phone from fastboot.
Open ADB & Fastboot and type "fastboot devices" (without quotes, always without quotes) - this will tell you if your device is properly detected, if it is, you'll see bunch of numbers and letters.
Now you'll need to extract a couple of .IMG files from your official ROM. This is how you do it. Your official ROM has 1 single file that's called UPDATE.APP. Open Huawei Update Extractor and open UPDATE.APP in it.
You should see a whole list with different .IMG files. You'll need to extract only a couple. BOOT.IMG - RECOVERY.IMG - CUST.IMG - SYSTEM.IMG
Now that you've extracted them all you'll need to start flashing them 1 by 1. This is how we do it
fastboot flash recovery RECOVERY.IMG
fastboot flash boot BOOT.IMG
fastboot flash cust CUST.IMG
fastboot flash system SYSTEM.IMG
You can drag and drop the IMG file into fastboot for your conveniance.
Now you need to place the actual ROM in the root of your SDcard.
On your SDcard make a folder called dload and put UPDATE.APP in it.
Now force update by turning off your phone and then power it back on while holding all 3 buttons pressed in. When screen comes on release Power button, but keep holding the other 2 buttons down.
Now your recovery should start wiping and installing the ROM and you should be saved
Let me know if you need more help

I flashed all the images you named, and after that I can't enter in recovery. Tried flashing twrp, still can't enter. Tried with power + vol+, nothing, tried with stock power + vol+vol-, still nothing. And access bootloader I can only with usb connected. Tried from another update.app, same result. Phone unlocked.

Just yesterday i bricked my phone too and i've spend 18 hours unbricking it, until i realised that the version of TWRP is directly related to the version of EMUI that's on your phone. As i was trying to install the old B126 with EMUI 2.3 i had to use TWRP 2.8.1.0. Once i installed it, i was able to enter into recovery and erase all data in orded to start over. Maybe you have the same problem.
EMUI 2.3 - TWRP 2.8.1.0
EMUI 3.0 - TWRP 2.8.7.0
EMUI 3.1 - TWRP 3.0.0.0
Try using TWRP that matches your EMUI version and let me know if it works for you

Well, somehow after posting I got working TWRP and got back to X-Rom, because for some reason, I can't install other custom ROM's, because of infinite bootloop. So I wanted to get back to stock firmware. So I tried all you steps and got bricked. For some reason, when I tried to install stock rom I got, "verifying install package" and after few seconds "FAIL". So I kinda stuck to one ROM

I see that X-Rom is based on B125. Did you try flashing .IMG files from the same ROM or did you use some other?

I finnaly did it, week ago. I downloaded stock rom (don't remember which, but recovery started working). Then I just "forced update" with latest full rom. and now I have B852. :fingers-crossed:
My main problem was that stock recovery would not work, but I managed somehow to get it done and after that point it was all nice and clean. Thanks for helping out!

Firmware flashing .zip extension

http://forum.xda-developers.com/z3-compact/development/list-pre-rooted-firmwares-6-oct-2015-t3218820
Above the link there is prerooted firmwares. I want to flash 6.0.1 firmware by using flashtool but when I choose flashmode, flashtool could not see the firmware. It is in zip format. I opened and extracted the fw but nothing changed. I changed the extension to .ftf but no change occured.
How can I install firmware by using the link above?
Can you help?
How to flash
Important: Make a backup before flashing!
Download and copy the pre-rooted firmware into the micro SDcard
Reboot your phone, boot into the recovery before the phone boot into Android OS (if you knew how to do it). If you using XZDualRecovery, press VOL DOWN to boot into TWRP or VOL UP to boot into CWM after your phone vibrate twice. I recommended TWRP!
Wipe /data, /dalvik-cache, and /cache (recommended)
Open "Install ZIP" and go to the location where you copied the firmware
Boot your phone. It will take 10 minutes to boot for the first time

[SOLVED] Stuck with TWRP - Can't flash OTA package

Hey everyone !
I have a rooted Honor 5C NEM-L51 (European variant) with TWRP custom recovery and, as some of you may know, Nougat update is now available to download using Huawei Firware Finder.
However, a stock recovery is needed in order to get OTA updates and since I couldn't find a stock recovery image by browsing the web, I decided to go back to a full stock ROM.
So I tried to do this the usual way : creating a dload folder, placing the update.app file in it, powering off the phone and back on by pressing simultaneously the volume up, down and power button... but this always lead me right to TWRP, no matter how many times I tried. I restored my phone from soft brick using this method about two months ago with no issue, but now I can't get it to work, even if I release the power button once the phone boots or do any other shady manipulation. Could this have anything to do with the latest TWRP update ?
I also tried to do the "Power on method" by dialing " *#*#2846579#*#*" to go to the project menu and flash the file from here, but it rebooted to TWRP...
I'm at a complete loss here. Can anyone please help me with this ?

Thank you for answering. The problem is, I don't know where to find stock recovery image, all I can find with Huawei Firmware Finder is the full stock ROM. Browsing the web didn't help so far.
Can I flash the whole ROM through ADB ?

Extract the update.app of full stock rom using huawei update extractor. There u will find recovery.img. Extract it and flash using fastboot.

I did that and then tried to install the update through the dialer. It rebooted and I'm stuck on "Your device is booting now..." screen. Can't even turn it off, it reboot automatically to this screen. Seems like there is no recovery at all and it tried to do the update through this inexistant recovery no matter how many times it reboot...
What can I do now ?

Don't do it through the dialer. After flashing the stock recovery, just restart and then try the three button configuration(volume up + volume down + power)

I can't. I am stuck on the "Your device is booting now..." screen. If I turn it off, it automatically turns on again to this screen.
Edit : Nevermind, looks like I didn't press the button correctly. Only the recovery was missing, I finally could boot to system by pressing the power button. Then I reinstalled TWRP with ADB and restored my nandroid backup. Back to the start...
I may have a hint about what went wrong. Extracting the Nougat UPDATE.APP file gave me two recovery files : recovery.img and recovery2.img. I only flashed the first. Any idea why there were two of them ? I am going to try with the FULLOTA-MF file (tried with the FULLOTA-MF-PV file before), or maybe should I try to extract files from the previous update ?
EDIT 2 : Still stuck with TWRP. I extracted several UPDATE.APP files and all have two RECOVERY.IMG files. I tried flashing them both, one after another and then reboot to erecovery, but TWRP is still here. How can I get rid of it and get back to stock recovery please ?

I have flashed several times Twrp recovery on my honor 5c, and i didn't even had to flash the stock recovery to get back to stock rom. I had placed the dload folder with full update in it, and used the 3 button method to flash the full rom. And i was once again in full stock including recovery. Try this. If it doesn't help, just flash the stock recovery. Then type fastboot reboot, let it boot. Then power it off. Now press volume up + power button. Just see which recovery it boots.

As I said, the three buttons method is not working and boot right into TWRP.
Which stock recovery ? There are two of them. Anyway, I tried this again, it led me back to the endless "Your device is booting now..." screen.

Well, I tried with or without uninstalling SuperSU which has an option to try to restore stuck boot and recovery images (which didn't work in my case).
I used adb to reboot into bootloader, from where I flashed either RECOVERY.IMG or RECOVERY.IMG and then RECOVERY2.IMG which I got from Huawei Update Extractor and reboot from fastboot. Then I tried to power off and back on my device by pressing volumes up and power button which led me to TWRP or endless booting screen. Flashing boot image from Update file gave me the same result.

Did that. I even flashed the previous version of the official TWRP beforehand. Still nothing. I even wiped everything from TWRP except internal storage and external SD card and still, the three buttons method led me right back to Meticulus TWRP.
However, I did notice something very strange. If I boot normally by pressing the power button and then, on the "Your device has been unlocked and can't be trusted" screen, press the volume up button to "boot into erecovery to restore my device", it boots into... official TWRP 3.1.0.0 !!! What the hell ?!
Do you have any idea ? This whole situation is so weird...
EDIT : This is just complete nonsense. I even wiped the internal storage and this abomination of TWRP 3.1.0.0 was still there. I really am at a complete loss here. ><
