I flashed TWRP to boot, not recovery - Huawei P9 Lite Questions & Answers

Hi,
My phone is Huawei P9 Lite VNS-L21C432
I accidentally flashed TWRP to my boot partition, not my recovery partition.
Now when I boot my phone, I get the TeamWin TWRP (3.0.2-0), not my OS (MM Emui 4).
In Install TWRP option i have only "Cust" storage in storage list. In Mount TWRP option i have Cache and Cust only and I can't check Data, System MicroSD Card, USB OTG
What should I do next?
Is there a way to get the original boot for the phone?
Help!

I solved the problem myself.
Below is a description if someone needed it.
Repair command:
Code:
fastboot flash boot BOOT. img
I extracted the "BOOT. img" file from the UPDATE. APP file with HuaweiUpdateExtractor app.
UPDATE.APP was from stock rom as I had on my phone.

I can't understand what you mean. If you want to install stock rom from TWRP recovery, you have to modify updater-skript.
Why do you can install only the twrp recovery 2.8.7.7, when we have the twrp recovery 3.0.0.2
File img you can flash from fastboot mode. Commands:
fastboot flash system file.img
fastboot flash recovery file.img
fastboot flash boot file.img
or
fastboot boot file.img for example twrp recovery img or stock recovery img. This is command for once booting.
I want to return to original firmware , i download it from the site of asus. So, i booted twrp in fastboot mode (i tried different version of twrp, but the only that starts is the 2.8.7.7 version) using adb.
Now i am in recovery with twrp 2.8.7.7. I can push using .zip files or img files on internal storage.
But i have different problems with this recovery:
IF i use wipe function: error opening sys, could not mount, enabe to mount, ... (failed)
If i install rom or firmware with zip files: error unable to mount, unable to find partition for path.... (failed)
Adb sideload goes failed too.
What should i do???
I think that the problem is in the internal partition... I have to install using a min usb ext storage? or what????? thanks :fingers-crossed:

Easiest way to fix your phone is flash stock rom from stock recovery. Stock rom put to sd card. Reboot to stock recovery and choose flash rom from sd card. New version number system must be the same or higher than installed in the phone.
Do you want to return to the lower version of Android.

Stock recovery doesn't work man. The only recovery that works is the twrp 2.8.7.7. But it has problems.

Do you have Lollipop or Marshmallow and what is your version number.
For Marshmallow you need to this working twrp recovery.
https://drive.google.com/file/d/0B7F3ZXr565GkY28yUjhfRkd5MUk/view?usp=drivesdk
For Lollipop you need to this working twrp recovery.
https://drive.google.com/file/d/0B7F3ZXr565GkY1NQbUtoVzdwWEU/view?usp=drivesdk
If you haven't installed stock recovery, it's not no problem. You can it flash from fastboot mode.

How did you flash the file twrp.img.
OK guys I've solved the problem. I moved in this way:
1) Volume up + power to go in fastboot mode
2) after installing adb and the other drivers, i've insered these commands:
fastboot erase cache
fastboot erase userdata
fastboot erase system
3) after downloading twrp version 3.0.0 (for the zenfone 2 laser), I load it using the command "fastboot boot (name file twrp).zip"
4) the recovery starts automatically. Now i downloaded the file "back2stock.zip" and the original firmware (WW, worldwide) form the official site of the Asus
5) this passage is the most important:using 7zip I've extracted the file zip of the firmware and the backtostock, then i created a new file using 7zip : in this new zip i've loaded the files inside back2stock and the files file_contentexts, system.new.dat, system.patch.dat, boot.img e system.trasfer.list inside the zip of the official firmware
6) I've loaded this new file on the phone using the command "adb push (new file name).zip /"
7) at last i have installed this file on the phone ENJOY it

The steps listed in this process WILL wipe your userdata. If you have anything you need to save back it up first.
Prerequisite:
Unlocked bootloader.
FOR LINUX USERS. If you're using a linux distro then congrats this is all you should have to run. open command prompt and run this. "sudo apt-get install adb" without quotation marks. then follow Motorolas bootloader guide in provided link. continue to step 1 after.
FOR WINDOWS USERS.
ADB/Fastboot installed on your machine ( https://developer.android.com/studio...platform-tools ) If you have issues with commands make sure you have a current build of ADB and fastboot.
Minimal adb/fastboot v1.4.3 installer can be found here. https://androidfilehost.com/?fid=746010030569952951

DECRYPTION AND BACKUP.
NOTICE
IF YOU YOU ARE USING THE 32GB MODEL OR THE 16GB MODEL AND ARE ON ANDROID 9 (PIE) PLEASE USE THE ANDROID 9 (PIE) MODEL TWRP. USERS WITH THE 16GB MODEL AND THE 32GB MODEL ON ANDROID 8 (OREO) WILL STILL NEED TO USE SEPERATE TWRPS
MAKE SURE TO SWIPE RIGHT IN TWRP TO ALLOW SYSTEM MODIFICATIONS.
Step 1.) Download and extract twrp image to the ADB/Fastboot folder on your computer.
FOR ANDROID 8 (OREO)
16gb model twrp: https://www.androidfilehost.com/?fid=6006931924117921836
32gb model twrp: https://www.androidfilehost.com/?fid=6006931924117927211
FOR ANDROID 9 (PIE)
https://www.androidfilehost.com/?fid=6006931924117921849
Step 2.) Reboot to your bootloader. You can do this by turning on your device and holding the power button and volume down button at the same time.
Step 3.) Once the device reboots to the bootloader type the following from your computer with your phone connected via USB.
Code:
fastboot boot twrp.img
Step 4.) Once TWRP boots from your computer type (it may take a bit to boot because it is trying to decrypt your userdata, but it will fail and prompt for a password. Just click cancel)
Step 5.) time to backup your stock recovery and stock boot. use these commands one at a time.
Code:
adb pull /dev/block/platform/soc/7824900.sdhci/by-name/boot stockboot.img
adb pull /dev/block/platform/soc/7824900.sdhci/by-name/recovery stockrecovery.img
This will backup your stock boot and recovery images if you need to revert to stock later.
Step 6.) time to decrypt which will also format your data so make sure to make a backup. while still booted in twrp touch the "wipe" button then touch "format data", type yes and after its all done reboot to bootloader use this command.
Code:
adb reboot bootloader
CONGRATS! if you read this correctly and or didnt skim then you have successfully decrypted your device and backed up your stock recovery and stock boot.img. proceed below for root process.
ROOT PROCESS.
Step 1.) Run the following command from your computer to install the TWRP image to your device.
Code:
fastboot flash recovery twrp.img
Step 2.) Use the volume keys on the device to select boot to recovery and TWRP will boot up again. swipe right to allow modifications. IT SHOULD NOT ASK YOU FOR A PASSWORD THIS TIME IF IT DOES YOU MESSED UP DURING THE DECRYPT PROCESS
Step 3.) Follow this link to the creators site to download the disabler zip. https://zackptg5.com/android.php#disverfe download it to your ADB/Fastboot folder.
Step 4.) Download the Magisk Beta v20.0 and or the latest zip file from https://github.com/topjohnwu/Magisk/releases to your ADB/Fastboot folder. (I personally use beta so I use beta in this guide but you don't have to)
Step 5.) Run the following command to push the dm_verity force encrypt disabler and magisk zip to your device
Code:
adb push Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip /tmp
adb push Magisk-v20.0.zip /tmp
This will push the Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip and Magisk-v20.0.zip to your /tmp folder
Step 6.) Flash Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip from TWRP using the install option and navigate to the /tmp folder to select it and install it.
Step 7.) Flash Magisk-v20.0.zip from TWRP using the install option and navigate to the /tmp folder to select it and install it.
Step 8.) Reboot your device
Step 9.) Just wait for the device to boot up. might take a bit and it might seem its in a bootloop but if you followed this guide exactly as is just wait it out it took about 5-10 minutes before i got to the "lets get started" screen after updating to pie (android 9)
Step 10.) Verify Magisk Manager is installed and the root functionality works. sometimes the manager apk wont be installed so download the magisk manager apk from the provide links. click advanced to see if the boxes are unchecked. (2022 edit) If you see magisk app and magisk needs updated you can do it but I can't confirm if it's safe and what works and doesnt after
CONGRATS! IF YOU DIDNT SKIM MY GUIDE YOU SHOULD HAVE A SUCCESSFULLY ROOTED AND ENCRYPTION DISABLED DEVICE, HAVE FUN.
IF YOU MESSED UP, DIDNT PUT A COMMAND IN CORRECTLY, SKIMMED, OR ARE INA GENUINE BOOTLOOP/BRICK THIS SECTION IS FOR YOU
Step 1.) DOWNLOAD STOCK FIRMWARE HERE FOR JETER AND CERTAIN ALJETER DEVICES (from what i can tell usa variant aljeter devices are consided jeter) https://mirrors.lolinet.com/firmware/moto/jeter/official/ IF YOU REMEMBER OR WROTE DOWN YOUR SW CHANNEL VERSION THEN DOWNLOAD STOCK FIRMWARE FOR BASICALLY EVERY OTHER ALJETER DEVICE HERE. https://mirrors.lolinet.com/firmware/moto/aljeter/official/ UNZIP STOCK FIRMWARE TO YOUR ADB/FASTBOOT FOLDER TO FLASH IT. TO REVERT BACK TO STOCK YOU HAVE TO REFLASH STOCK FIRMWARE FROM THE BOOTLOADER if your device is bootlooped or bricked or not working right you have to reflash the stock firmware your device came with. PLEASE INPUT THESE COMMANDS ONE AT A TIME DO NOT DO THEM ALL AT ONCE. I KNOW ITS A HASSLE BUT IT GUARANTEES A SUCCESSFUL REFLASH. I CANNOT EMPHASIZE THIS ENOUGH

I have the same issue. I used the recovery steps to go back to stock but every time i re-attempt to root/install twrp the bootloop comes back:
Also, it's failing to mount /data after Resurrection Remix wouldn't boot and it keeps giving me the unable to mount /data (invalid argument) problem. I need help badly. Can you help? Is it the TWRP's fault?

Are you encrypted? Because twrp will do that if you are. You have to use the wipe > format > type "yes" to continue method to remove encryption. Then reboot from twrp, directly back into twrp. Then it can mount /data properly, at which point you need to flash the encryption disabler. If you don't disable encryption you'll keep running into the same problem. You only have to do that once. After that you can use the regular wipe option. If you ever flash the stock vendor.img you'll need to do it again.
Also, please make sure twrp has been flashed to recovery. I don't think it'll work if you just boot through fastboot. If you followed all these instructions and magisk still refuses to install, or gives you a bootloop, then it's a ROM problem and not TWRP. Should that happen, let me know and I'll flash Resurrection remix and see if I can figure out what's going on. I've had ROMs refuse to be rooted before. Descendant ROM had this problem on some older builds.

as for me: I followed the instructions which tell us to only boot twrp during the data format and only then actually flash twrp.
but my problem is no magisk, as I always root my phone whenever i revert back to stock. it's just that decryption is not working on my xt1922-5

Do it like this.
1. fastboot flash recovery twrp.img
2. Use the volume keys while still in fastboot to select "recovery" then hit the power button.
3. Hit cancel at the decryption screen when twrp boots up.
4. In TWRP select wipe > format > type "yes" to continue. Do not reboot the phone yet.
5. In twrp select reboot > recovery.
6. Once twrp boots up again, select mount and check the boxes for /data, /system, /vendor, /cache.
7. Now flash the universal encryption disabler.
8. Let it boot once, then go back into recovery and flash Magisk.
This should solve your problem.

My issue is as follows:
I had rooted my g6play months ago, back when pie came out on Ota for it. The guide I followed didn't have me disable encryption, which at the time wasn't a real big deal, with my only loss being the inability to do nandroid backups. But fast forward to now, when Resurrection Remix GSI came out, I was immediately interested as I think that rom could be a great experience.
So I decided to come here in this guide because I might as well disable encryption, right? So I flashed the new twrp and did get it to wipe and disable the encryption (in the option that has you type in yes) and proceeded to flash RR, it booted to the boot anima9and there it stayed for a good 30 minutes before I decided to try the older GSI image, maybe that one would work.
But nope, I immediately got the unable to mount /data bootloop and successfully flashed my stock rom and tried again, this time flashing the new twrp right off the bat. No avail. Now everytime i go into a freshly flashed twrp, i get no password prompt, and when i try to access the internal storage, it comes up as 0mb. Even my Linux complains that it couldn't mount my Internal storage as only the SD card shows up (weirdly enough I was able to successfully push dm verity and magisk to /temp no problem but they fail upon flashing)
Edit: gotta mention that after the first time I did the pull adb command to get the backups, the command refuses to work anymore. And also that I still have an old twrp backup stored (did that today before trying this)

well i also couldnt make the backups, fastboot just tells me the file doesnt exist. and for the internal storage: while you are encrypted, that is how it works.

Go into the wipe menu, advanced wipe, check data and hit change file system. change data back to f2fs. When you guys format and don't immediately reboot straight to recovery, data sets to Auto and freaks out

the multiple times i checked, the file system was always f2fs, but sometimes ext4
and also: Do you mean we should do that after we try to format with the format data (typing yes) option? If so, it doesn't work as the internal storage won't mount. Won't even show up on my computer

If you change the file system, it'll format, even if it says it won't mount. Changing the file system will force it to format. Even if it says f2fs, hit change and select f2fs anyway.
If it doesn't, format from fastboot, boot system once then go to recovery

Alright, let me work through this.
I'm currently on a stock firmware and it's working fine.
Right now i have to:
1. boot into recovery twrp
2. change the filesystem of data
3. flash recovery and boot into it
4. format data(yes option)
5.check and change the file system again
6.reboot straight back into twrp recovery from recovery
7.flash dm verity zip
8.flash magisk
9.boot
Is this correct? and as for attempting to install a GSI image again, should i attempt to flash it before the verity zip and magisk? (i'll also be flashing micro gapps) or do i let it boot into system once and then i do it? (by wiping data/dalvik/cache/system)

Let's simplify. If everything is working,
go to fastboot
Flash recovery (boot doesn't seem to be working here)
Fastboot flash recovery twrp image
Select recovery, when the decrypt menu comes up, hit cancel
Wipe menu,
Swipe to factory reset
Go back to wipe
format data, yes,
Reboot recovery
Flash disabler
Flash magisk
And yes. Boot system then GSI flash, then factory reset before magisk

No that's fine

If you change the file system, it'll format, even if it says it won't mount. Changing the file system will force it to format. Even if it says f2fs, hit change and select f2fs anyway.
If it doesn't, format from fastboot, boot system once then go to recovery

Data is set to emmc file system, won't mount and filesystem won't change at all and won't format
Edit: only happens when i try to change it to f2fs, changed it to ext4 with no issues and it mounts sucessfully with ext4 but won't let me format data
I get the mkfs.f2fs -t 0 /dev/block/mmcblk0p56 error 1, unable to mount data whenever i try to change to f2fs. Has my previous failed attempt at installing GSI **** with my filesys?

But data won't work as ext4, hence the boot loop
Try going to fastboot and typing
Fastboot -w
Then boot to recovery

ab flashing

Is there a way to determine if I have stable oos
.13 is on both A and B?
Thanks
fastboot getvar current-slot
will return with either A / B AS active slot
fastboot --set_active=(Whatever slot your not on)
YOu just need to go to settings, check sys ver. should say OS VERSION somewhere, reboot back to fastboot mode and type above commands. You can also
fast boot boot twrp.img
with this updated official (rename to twrp.img) : https://eu.dl.twrp.me/fajita/twrp-3.3.1-0-fajita.img
permanent twrp installer zip https://eu.dl.twrp.me/fajita/twrp-installer-3.3.1-0-fajita.zip
it will boot then you can copy this zip file to internal and have twrp installed via zip on both slots, you will need to reinstall magisk after on both slots, just make sure to boot into system after you flash magisk the first time before changing slots and then flashing magisk again to inactive slot by fastboot --set_active=(desired slot) and booting twrp img and flash magisk that way..IF U INSTALL THE INSTALLER ZIP(PERM TWRP) ONLY CHANGE SLOTS IN TWRP BY CHOOSING SLOT AND THEN YOU MUST REBOOT BACK TO RECOVERY(OR SYSTEM IF YOU STILL NEED TO VERIFY OOS VER) UNLESS YOU ARE PERFORMING A CLEAN FLASH OF A NEW ROM FROM SAME OOS BASE ON BOTH SLOTS. Then you would have found under settings if you are indeed on same oos on both slots. SO BOTH SLOT A AND B HAVE desired base, you would then boot the img via fastboot boot twrp.img (RENAME TWRP-3.3.0.1-fajita.img to twrp.img) then afterbooting mount all partitions and you would wipe dalvik/cache /system and /data only, (i like to wipe internal sometimes aswell when doing clean flash to make sure device is gutless) then you can remount /system and mount usb storage and copy rom zip to internal and then flash, it will complete and you want to reboot system, it will say no os installed/areyou sure. just say yes and reboot, will boot into custom rom. then you must reboot to bootloader after booting rom once, then fastboot boot twrp.img choose opposite slot (this is the only time i choose to make another slot active while not actually doing a reboot back to recovery because i dont flash the twrp perm-installer untill after i successfully get custom on both slits to avoid recovery issues /i have had many issues before with twrp regarding slot changing and how it flashed to a/b systems with custom roms built in recoverys. so i always do it this way) mount all partitions if not already, again, wipe /system /data /dalvik. you will need to go back and remount all partitions in twrp and then recopy the rom to internal from pc with mount usb storage and then flash rom reboot. then fastboot boot twrp, and install the installer zip to retain twrp forever. if you say ever need to update rom just dirty flash on the slot your on/ reboot system after/ go back to recovery(fastboot boot twrp.img from pc because you may lose twrp-perm after flashing rom depending on rom) choose other slot via twrp in reboot section, then choose reboot system. (recovery--(only works if twrp-perm is installed, or else if you dont perfer having twrp permanently just choose reboot system, then reboot to fastboot after, and reboot twrp.img) then dirty flash on the slot we have just changes to and then rom is updated on both slots, then you may reflash twrp perm(installer).zip and then you need to flash magisk and reboot and then reboot back to recovery and change slots reboot back to recovery and flash magisk once more... YOU MUST FLASH MAGISK AFTER TWRP EVERY TIME THEN REBOOT BEFORE GOING FURTHER INTO STUFF AS ALWAYS OR YOU WILL NOT BOOT . if you want to update to open beta base if still on stock .13 on both slots use above steps instead of /custom rom/ you can be flashing the /beta rom/full ota zips/ on both slots then you will have new base of beta(whatever beta you choose) then you can flsh custom rom on top of that. if you flashed a custom rom over the .13 and wish to update to beta base instead of .13 you will need to reformst the device and lose all data unless you perform a back-up prior

How to flash GSI-s on ATU-Lxx after the April 2019 security patch?

Code:
*** I'm not responsible for dead sd cards, thermonuclear war, getting you fired because the alarm has failed. Your warranty is void if you continue! ***
Code:
*** Everything you read here was a success for my ATU-L21 variant of the Huawei Y6 (2018). Don't be alarmed, the files mentioned here are 100% compatible with the phone ***
Hey, dear Forum Users!
Prerequisite things:
Install HiSuite, it has the proprietary drivers needed to operate ADB and Fastboot.
You need to unlock your bootloader, get them from dc-unlocker, it's 4 euros.
You need the following:
The 2018 kernel and vendor image: https://drive.google.com/open?id=1aFTTMSArwBuF5tsJBkWJ7f_d7IQc7zyy (credits goes to Boki, @deadliestPixel on Twitter)
You need this TWRP to boot up: https://forum.xda-developers.com/huawei-y6/development/guide-backup-current-partitions-t3853831 (thanks to @leepicstitch on Twitter for finding this)
You'll need to flash this TWRP to recovery_ramdisk: https://www.mediafire.com/file/7nyab3whb6bp7r8/twrp_3.2.3_atu.rar/file
Choose a ROM that will suit your needs from this thread: https://forum.xda-developers.com/huawei-y6/development/index-list-roms-y62018-t3854167 or try other GSIs
(I recommend Resurrection Remix with gapps and su)
So if you have everything, let's do this.
Before we start everything make sure you have a microSD card that has the VENDOR.img and the system.img you downloaded.
So, we need to make a backup of our current recovery_ramdisk for later, you can follow the TWRP XDA post above to do so.
After you've done that go to fastboot and flash the older kernel with this command:
Code:
fastboot flash kernel /path/to/KERNEL.img
Flash the recovery you downloaded with
Code:
fastboot flash recovery_ramdisk /path/to/recovery.img
Now boot up that screen flasher recovery you had before. If you booted it up just reboot the phone to recovery with
Code:
adb reboot recovery
, the Y6 Prime 2018 recovery should boot up.
Now go to Install -> Change Storage -> Micro SD -> flash image -> choose the vendor.img and flash it to the VENDOR partition.
Do the same for the system.img file.
Go to the main menu and go to wipe, then wipe dalvik/art cache, cache, data, internal storage.
go to the main menu and go to reboot, then bootloader.
Now we need to flash our stock recovery_ramdisk back, because eRecovery will complain about a damaged data partition. Do a low level data format, type yes, and when the emui recovery pops up, do another data wipe.
Now, just hit reboot and the phone should boot into the ROM.
Turn off the phone and reboot back into fastboot and flash back the Y6 Prime 2018 recovery just in case if eRecovery wants to do something weird.
Now just reboot your phone and enjoy it.

One question, I have to flash the system.img as a vendor?... (BECAUSE YOU SAY ABOVE THAT WITH THE SYSTEM. IMG WE MADE THE SAME AS WITH THE VENDOR)

System.img goes to the system partition, obviously.
This worked flawlessly, the only difference is that I couldn't flash Kernel.
The ROM I used: PHH Treble 9.0 github.com/phhusson/treble_experimentations/releases/tag/v117
The steps I took:
- Factory reset phone
- Backup stock recovery_ramdisk
- Download kernel (unused) and vendor
- Boot fastboot
- Flash twrp in recovery_ramdisk
- Boot twrp
- Flash vendor, flash system
- Clean caches
- Reboot fastboot
- Flash stock recovery_ramdisk
- Reboot
erecovery did not complain, everything was ok there

Since the ATU-L21 and L22 is the same hardware wise it should work without any problems.
i keep either getting a black screen or vendor not mount or system not mount if not vendor ( ATU-L22 Y6 2018 )

mi 9 t anti roll back to 1 and fastboot loop

Hi, I've been trying to get out of this situation for days.
My mi 9t went into boot loop after having wipe a twrp wipe.
Now if I try to flash a ROM it returns the antiroolback error check because my arb is 1 and the rom I find is 0.
I can't even install the twrp anymore, the installation process with fastboot is successful but it always restarts in fastboot and not in recovery.
Can someone help me?
