[GUIDE] Return your OPO to 100% Stock (Current Build - CM13.1.2 - ZNH2KAS3P0)

So, you've unlocked your bootloader and are enjoying some rooted goodness on your phone. You then realise you've got an issue with the phone and forgot to make a backup of your stock ROM! Not to fear, this guide is for you! This will reset the phone back to it's out-the-box state, locked bootloader and all, running the latest ZNH2KAS3P0 build so you can return it for RMA/sell it. This also works to go back to CM13.1.2 from Oxygen OS.
It's recommended that you have adb/fastboot in your System Path. This makes it easier to run commands as you don't always have to 'in' your adb/fastboot folder to run the commands. This guide should help you with this but if you don't want to do this, please copy/extract any files into your adb/fastboot folder before continuing...
1. Download the factory image
Cyanogen released the factory image for the OPO but didn't include any batch files to automate the process. I've repackaged the images into two seperate ZIPs:
ZNH2KAS3P0 16GB: DOWNLOAD
md5: be471f6bfc707f86a0af1eb175ec9aad
ZNH2KAS3P0 64GB: DOWNLOAD
md5: c371bc0cb4ef67999d21f5275c5a587b
*** These ZIPs are not flashable so cannot be flashed via TWRP ***
2. Extract the factory image
Using your favourite file extraction program to extract the package to your Desktop (I use 7-ZIP). *** Remember, if you don't have adb/fastboot in your Path, extract the image into your adb/fastboot folder ***
3. Flash the factory image
Once you've unlocked the bootloader, and rebooted the phone, turn the phone off and back on into fastboot mode and reconnect it to the PC. You can now run the flash-all.bat (Windows) or flash-all.sh (Linux) file. These automate the flashing process. Once complete, the phone will reboot.
*** Some users have had issues using the script in Linux so in these cases extract the ZIP file and flash each IMG individually ***
fastboot flash modem NON-HLOS.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash dbi sdi.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn
fastboot flash tz tz.mbn
fastboot flash LOGO logo.bin
fastboot flash oppostanvbk static_nvbk.bin
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img (the filename is the same in both ZIPs so make sure you're using the right one for your device)
fastboot reboot
4. Reset the tamper flag/lock the bootloader
There is a flag/bit on the phone that is triggered when you unlock the bootloader and even relocking it won't change this flag back to standard. Luckily, @Mnt-XDA has a script that you can flash which resets these flags so OP/anyone else is none the wiser! To do this, read and follow THIS thread
5. Reboot the phone
Says it all really - you're done!

And why do you need to unlock the bootloader to flash the factory image ????

Because you need access to flash the partitions. If the bootloader is locked you cannot do this. If you're device is still locked from day 1, this guide isn't for you as you're already 100% stock and a factory reset will do this job just fine
EDIT: Actually, it's a bit redundant as why would you need this if you're NOT unlocked! I'll edit the OP

Somehow I was thinking that if the signatures match, flashing the FACTORY image would be allowed without unlocking bootloader, hence the question has arisen.
In a way, you are right that if someone is 100% stock, why to bother flash a stock...
But the reasons could be different, like from pure laboratory experiment to the unable to install OTA (for whatever reason) and need to update OS...

May be worth including this work here by Mnt-XDA
If you are returning to stock for selling / returning etc people may want to reset the tamper flag too.

I know what you mean, but it's the same with Nexus devices - you cannot flash the image unless the bootloader is unlocked

Yeah was looking to add that in at some point, this is still a work in progress as it were...I'll add it in when I get a chance

To make this thread more useful for those who aren't familiar with command line, make sure to tell them to:
1) Download the zip file and extract it onto desktop (what a mess)
2) command line cd desktop
3) Enter each one of those command lines
4) Be happy in the end.

Thank you. Any reason why I can't just fast boot the boot.img file only (ala carte)? I am on CM11s rooted with TWRP.

I fastboot flashed the boot.img file sucessfully. It did not fix my wifi problem. So, I tried fastboot flashing the NON-HLOS.bin file. It appears to have an error code. Here is the result.

Is your phone the Chinese OPO or the CM OPO?

CM OPO coming from paranois android

Rollback yo b386 from b577

Hi, I need help, I have the Chinesse version of mate 8( NTX AL10), and I installed the 577 version in HiCare, but Im having too many problems and I want to rollback to Android 6.
Someone can show me the way? I tried to install twrp recovery (I have the bootloader unlocked), and I couldnt format data because I couldnt access to internal storage in the recovery.
Thanks

maybe u have to do a factory reset first. if u cant do it with twrp try to enter the stock recovery and do it before flashing. hope that it works this time.
about me, i was on nougat beta, twrp gives me too much errors when i want to format data and system, i installed stock recovery and did a factory reset and i used dload folder, now im on EMUI 4.0 (B180)
dont worry every problem have a solution. good luck
Posted from Mate 8.

Or with Rollback UPDATE.APP.
My Mate 8 is L29C636,i convert to AL 10 with B577 and go Back to L29 C636B211 without any Problem.
I can upload the UPDATE.APP later 92mb.

Use HiSuite via PC and roll back by updating to earlier versions! It's simple

And how did yo do? Can you explain please?

Copy the Rollback UPDATE.APP in dload Folder in Micro SD.
Change oem.info and custom.bin from AL10 to L29.
Boot in Bootloader and Flash Stock Recovery and reboot
This make Automatic a Factory Reset and Lock my Bootloader
Go to dailer and use this code *#*#2846579#*#* and go to 4.Software Upgrade.
After this Procedur copy my Original Firmware for c636B211 in dload Folder and make the same Procedur with *#*#2846579#*#*
After flashing the Firmware i am on L29C636B211
But you have a AL10,i think you flash the Rollback Update App
This Roll Back flash to Emui 4.0 and not to 4.1
After flash the Rollback,Download a Firmware for your AL10 with Emui 4.0 and flash this Update App via dload *#*#2846579#*#* here
This Methode can use with locked bootloader
Download Rollback
I think this works
If not take what was described above

Which original one though? I've been trying and downloaded any Full firmware I could find using a firmware finder, for my VNS-L31 but using the force update method in download so far all of them return an error: Incompatible with current version. I have also tried the fastboot update and separately flashing each file in the update.app . None work so far. I keep trying.

If you're on Nougat, try flashing it's files through fastboot. It worked for me, MM system.img gave me an error, but nougat flashed fine.

I believe ur in nougat beta... Just flash oem info and flash again the nougat from there you can start again and downgrade peacefully

your bootloader is locked

Thank you! I followed the instructions here with a slight variation. Because trying to install the update.zip file always gave me errors I extracted the update.APP with the update extractor tool and flashed cache,system,boot with fastboot. Then I opened the custom recovery, installed the other zip file and continued as instructed.

p9 lite stuck on huawei boot logo

My p9 lite is stuck on the huawei logo, its been a week now. it all started when I flashed a wrong update.app (i mistakenly flashed the rollback update.app while i was on b161)
now I cannot use the device anymore, i can only get to bootloader mode but cant flash anything
help

I had the exact same problem. I got out of that situation by rooting the phone, and re-flashing it.
However I already had the unlock code handy. If you don't have that then you are mostlikely f'ed.

My bootloader is unlocked yet I am unable to fastboot flash anything as i get errors.

HEY! I've done the same thing yesterday But now phone working great! I find the way
1. Download C432B160, Huawei Extractor and SRK Tool Huawei
2. Prepare your unlock bootloader code
3. Unpack UPDATE.APP by Huawei Extractor (You need files: boot.img, system.img, recovery.img, cust.img)
4. Go to folder SRK Tool Huawei -> Command
5. Put *.img files to Command folder
6. Put UPDATE.APP (Not extracted) on your sdcard in folder "dload"
6. Hold Shift + right right mouse button "Open the command line here"
7. Plug your phone in fastboot mode (vol- and power button then fast plug USB)
8. Type in cmd "fastboot devices" (Now you probably see your device)
9. Type:
fastboot oem unlock xxyourfastbootunlockcodexx
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash system system.img (that command takes 2-3 minutes)
10. Unplug Your device
11. Hold vol- vol+ and power button, it will install UPDATE.APP from your sdcard

Yes, you can't flash C432B160 if your phone is branded by operator, the flashing will always end at error. Flashing oeminfo.img and Huawei firmware is fully legal and you don't loose warranty. And debranding is a good thing because (in future) you can download faster official Nougat.

Alright so let me explain my situation properly (I'm a big dumb-doofy-doo so i'm not even sure if my phone is branded) I bought my phone off amazon last year and 2 days ago I made the mistake of trying to update it to Nougat using http://www.droidviews.com/update-huawei-p9-lite-manually-official-android-7-0-nougat-emui-5-0/ and the files for build number VNS-L22C636B360 however my build number is VNS-L22C636B101 (Huawei P9 Lite). using the first file called "update.zip" I tried upgrading but it said software update failed. I turned on OEM and tried using "update_data_full_VNS-L22_hw_spcseas.zip" to update. it worked but I don't think this was the full update as it rebooted and I was greeted by Huawei eRecovery which had three options: "Download latest and recovery" "reboot" and "shut down" so naturally I chose the first option. It however ended with "Getting package info failed". I tried it over and over but it didn't change. so this is where I because frustrated, and stupid, and factory reset my phone. it didn't make a difference. same eRecovery prompt (but did the reset take off OEM??) I took out my SD Card and replaced the Update.app with another one (I cant remember which I was sad but I definitely complicated matters more by doing this) and I came upon the same problem the person who made this post: stuck on Huawei logo. if I power it off it will vibrate and boot back up on it's own to get stuck on the Huawei logo thing (it wouldn't even do the pretty flowy smoke thing) so because of this it does not respond to the 3-button force update anymore idk why the only mode I can get it into successfully is fastboot mode but even after following the step by step answer I cant get it to respond to the 3-button force update (I also dont have the exact firmware for my build number) I did skip the bootunlocker steps because I dont have a product id or IMEI to generate a code from the Huawei website. in fastboot mode however it says "Phone Unlocked" and "FRP Unlock"
I dont know what to do... I think I need the firmware but I cant find it specific to my build number VNS-L22C636B101

First of all you must have your bootloader unlock code...
You wrote that you get error on flashing by fastboot probably "Command not allowed" because, your bootloader is locked (Yes it's only display "unlocked" I also got on that )
If you don't have code you can't do anything, sorry. You must send your phone to huawei store on warranty.
You don't have phone box?

ya

Ask your seller, hope you'll get a working phone

Mine was solved by booting to fastboot and did fastboot OEM unlock "unlock code" then fastboot flash recovery TWRP.img
Even though my bootloader was unlocked it worked

tq

HEY! I've done the same thing yesterday But now phone working great! I find the way
1. Download C432B160, Huawei Extractor and SRK Tool Huawei
2. Prepare your unlock bootloader code
3. Unpack UPDATE.APP by Huawei Extractor (You need files: boot.img, system.img, recovery.img, cust.img)
4. Go to folder SRK Tool Huawei -> Command
5. Put *.img files to Command folder
6. Put UPDATE.APP (Not extracted) on your sdcard in folder "dload"
6. Hold Shift + right right mouse button "Open the command line here"
7. Plug your phone in fastboot mode (vol- and power button then fast plug USB)
8. Type in cmd "fastboot devices" (Now you probably see your device)
9. Type:
fastboot oem unlock xxyourfastbootunlockcodexx
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash system system.img (that command takes 2-3 minutes)
10. Unplug Your device
11. Hold vol- vol+ and power button, it will install UPDATE.APP from your sdcard
12. Done!

You only think it's unlocked (yeah, it's showing Bootloader UNLOCKED) but no, it isn't. I don't know why, but you must unlock it first.

P9 hard bricked

This is my first time posting on XDA, so sorry if the formatting is bad.
I've tried to root my P9 lite installing TWRP and Magisk, everything went fine, until the last reboot that caused a bootloop.
Trying to fix this I mistakenly wiped the System partition (instead of Data), reading online people adviced to flash the update.zip, when i tried it I had "unable to mount /vendor" and "unable to mount /product".
I tried the update.app method and the eRecovery tool, but still nothing.
I read that the problem was probably caused by en error in boot.img or recovery.img, so i extracted those files from the firmware and flashed them using TWRP. By doing so i deleted TWRP itself leaving me unable to flash system.img.
I tried to flash it using fastboot, but every time i try to write a command regarding flashing i get a FAILED (remote: command not allowed).
Now i have a bricked phone, i can access fastboot but it doesnt seem to be working. I cant access adb since i can't access the recovery (at least i dont know how to ).
Any advices?
