Hey XDA m8s,
i want to decrypt my OP 3. So i completely cleared it and fresh installed OOS Beta 10. Now its still encrypted. I did this 5-10 times.
Bootloader: Unlocked
Recovery now: Stock
1. Tried fastboot wipe userdata
2. Tried TWRP Data Reset
3. TriedAndroid normal Factory Reset
4. Tried to install OOS with Stock and TWRP Recovery
Everytime I install OOS 4 or Beta 10 TWRP asks me for a password after installation to decrypt File System. I dont have any password and i dont encrypted my device.
And now there is coming a dm-verity error everytime i boot. I dont know what that means...
The device is working but i cant flash TWRP and install SuperSU or other Zips cause of this ****ty password that i dunno.
Any ideas??
thx m8s

The encryption will always occur if you don't flash supersu before first boot.
Dm-verity error is strange if you flashed the open beta or oos 4 from stock recovery. This warning only happens when you flash from twrp.
You need to do a format data from twrp or wipe data cache > erase everything from stock recovery to "decrypt" but you will lose all your files in the process

I flashed the official nougat update yesterday using the stock recovery and I somehow got the dm-verity error? I heard somewhere that I had to reflash the stock recovery even tho I already have it? I used to have TWRP but that was back in 3.2.2 of Oxygen OS but I switched back because I wanted OTA updates too work

Is the Dm verity error cause of android 7?

That DM verity screen is not an "Error" screen its just "Warning" screen meaning that the FW files were not digitaly signed. Its something Google introduced a while ago but has really started pushing since Nougat. There's no way to avoid it (except to flash a seperate script to disable it) theres one floating around here but might have been in Nexus thread. Personally i flashed 3.2.8 Fw after flashing OOS 4 and it got rid of the "Warning" but that might cause issues down the road. As of now though all is running as it should. hope this helped

is there a method to flash systemless SuperSU without doing a Factory Reset? // What is the password when i boot to TWRP when Android installed? On Android 6 was it possible? Is it new that Android encrypt the Filesystem or what??

ich hab gerade das selbe problem aber ich fürchte das nur ein entschlüsseln hilft ( also fastboot format userdata ). Und vor dem 1. start der systems eben supersu flashen.
english: I have the same problem and I think the only solution is a complete decrypt. And after this, flash supersu before you boot the system the first time.

The New Android 7.0 Nougat Introduced a bit of a secure partition Which Encrypt the system without asking The New Twrp Isnt Completely Compatible yet Due to New Kernel Sources not released This is a workaround to have root you have to factory reset in TWRP once to get it working
Here are the Proper Instructions to Install Oxygen OS 4.0 without DM - Verity Error and F2FS -
For Unlocked Bootloader + TWRP + Rooted users (Having any Rom installed before) -
Requisites -
Backup All your internal Storage Data - Sync all Google Stuff - backup all Messages or stuff.
Downloads -
Oxygen OS Official OTA Full Zip - https://docs.google.com/uc?id=0BzS3n...xport=download
Official Recovery ( Oxygen OS ) - http://oneplusroms.s3.amazonaws.com/...BmI3Z1Dri5Q=
TWRP Recovery 3.0.2 - 23 (IMPORTANT) - https://www.androidfilehost.com/?fid=529152257862684308
SuperSU 2.79 Stable - http://downloadmirror.co/Utz/UPDATE-...1211114519.zip
Custom Rom Based on OOS ( Choose any) - Freedom OS - https://forum.xda-developers.com/one...s-1-0-t3409348
Experience Rom - https://forum.xda-developers.com/one...-v1-0-t3522259
Hyper Stock - https://forum.xda-developers.com/one...stock-t3521946
Procedure -
1.) As mentioned, BACKUP EVERYTHING.
2.) Flash stock oxygen recovery though fastboot or in twrp.
3.) Boot to stock recovery, sideload Official 4.0 ota via adb.
4.) Reboot and dont set up device ( not necessary ) enable developer settings and usb debugging.
5.) Flash TWRP .23 NOT .28 (.28 is bugged with decryption and f2fs errors)
6.) Boot to twrp, wipe /data to f2fs and /system and /cache to ext4.
7.) As wiping everything,encryption and dm verity will be gone and copy any custom oxygen os build and supesu 2.79
8.) Flash any custom oxygen os build ( all these 3 builds flashes supersu itself, so no need to flash supersu, buy keep it for further later use.)
9.) Reboot, Setup and copy all ur stuff.
This method will surely get u a Rooted, decrypted, f2fs /data partition Oxygen Os 4.0.
For Stock/Twrp Recovery, Encrypted/Decrytped, Locked/Unlocked Bootloader, Unrooted Users (Those who dont want to root or decyrpt) -
1.) Backup is necessary as internal storage will be wiped, its a one time process as for now every Oneplus update will be f2fs /data compatible.
2.) ADB sideload 4.0 ota.
3.) Reboot and dont set up device ( not necessary )
4.) Go to backup and reset in settings, do a factory reset with internal storage ( This will wipe everything, BACKUP NEEDED )
5.) Let the process complete and check /data partition via DiskInfo app.
6.) If it isnt, do a factory reset again via stock recovery.
7.) If nothing helps, follow first method.
I cant guarantee this will work, but many users have reported this as working.
I think this will be sufficient.
oneplus fooling us??
is the open beta 10 and oxygen os OTA same????? they havent uploaded any links on the oneplus downloads page
You worry to much for a 2 seconds message...
So i had 4.0.1 rooted before. I decided to return to stock by flashing full 4.0.1 on TWRP. That's when I started getting the error. I flashed 3.2.8 on stock recovery 2.0 and dm-verity error is gone. But installing 4.0.1 on stock recovery 2.0 results to dm-verity error again. I cannot use adb sideload as my computer is too slow
More details: before, I successfully updated my OP3 with 3.2.8 to 4.0.1 without the dm-verity warning. After that, I flashed blu_spark's TWRP v11, swiped to allow modifications and rooted it with SuperSU 2.79 and flashed some mods, still no warning. Yesterday, I decided to return to full stock. I updated my TWRP to the unofficial 3.0.3-0 (the official one wasn't available yesterday yet), wiped system, cache, and data excluding internal storage, then flashed 4.0.1. The dm-verity warning started to show. I followed your guide and other guides here on XDA, I cannot fix it. The only solution I found is to rollback to 3.2.8, I installed the zip file on the stock recovery from your guide (flashing the recovery before). I'm having problems with adb sideload, PC lags so much and sideloading never finishes, so what I do is copy the zip file in the internal storage. After I flashed 3.2.8 and rebooted, the recovery was replaced by the V1.0 version that doesn't have the function of installing zip from internal storage, so I flashed your stock recovery again. Booting to the new recovery, I flashed the 4.0.1 zip and the dm-verity warning shows again.
Right now, my OP3 is on 3.2.8 with stock ROM, kernel, and recovery. No dm-verity warning. I don't know how to update to 4.0.1 without getting that again
Simple. New bootloader added that warning and the old one never had a dm-verity nag screen. Flash it and ignore it. It shows up due to TWRP installed.
Check the freedomos thread and download the 3.2.7 fw and flash with TWRP and its gone, I am not using the nougat fw on 4.0.2, always make nandroid backups
install beta 7 firmware
Don't bother! It's not worth it! It's just a stupid message!
I have tried by following these steps (I initially had twrp-3.0.2-1.28-oneplus3 installed):
1. booted to TWRP recovery;
2. copied recovery_OBT8N.img to phone;
3. installed stock recovery_OBT8N.img via TWRP as image > recovery;
4. booted to stock recovery (directly from TWRP);
5. while in stock recovery, I have wiped the phone (for a clean flash);
6. installed OxygenOS 4.0 (N) via ADB;
7. once the installation got completed, I rebooted the phone;
8. once the phone started, I did not finished the startup setting;
9. switched-off the phone and booted in fastboot mode;
10. flashed TWRP recovery - twrp-3.0.2-1.28-oneplus3 again;
11. switched off the phone;
12. started the phone in TWRP recovery; TWRP asks for a password to decrypt - ignore it;
13. wiped the phone (I wanted to do so to make sure it is a really clean install, even if this wipes everything);
14. rebooted again to TWRP recovery; this time I did not get any password prompt;
15. from TWRP, I copied SR1-SuperSU-v2.79-SR1-20161221223537.zip to phone storage (while connected to my laptop, obviously);
16. installed SR1-SuperSU-v2.79-SR1-20161221223537.zip, wiped data & cache and rebooted system;
17. everything went fine, with no dm-verity and rooted.
It will Keep showing Because You flashed Oxygen OS from TWRP . Try flashing this just after flashing the OS .
it will disable DM verity and disable force encryption .

Please try this method. Tested and it works for me.
step
Assuming your bootloader is unlocked. Copy
1. fastboot boot twrp twrp-3.0.2-1.28-oneplus3.img
2. Now you will be in TWRP, perform wipe -> Format Data, perform Wipe -> Advanced wipe "All folder" except USB-OTG
3. Reboot to recovery
4. adb sideload OnePlus3Oxygen_16_OTA_037_all_1701041839_401.zip (if adb cannot read, because filesize too big. Use laa_2_0_4.zip to fix the adb.exe first.)
5. After adb sideload done, reboot to TWRP immediately, enable MTP to copy the file: no-verity-opt-encrypt-5.1.zip into your internal storage and install no-verity-opt-encrypt-5.1.zip immediately.
Then everything will be fine.

I was not having any Issue . But Surely Your Help and concern is much appreciated
and Yes this is also one of the way to remove DM verity and use the zip
Currently using:
ROM - FreedomOS-2.1
TWRP - blu_spark_v11-oo3
Phone - Encrypted
I have the DM-Verity message at boot. Would reflashing FreedomOS-2.1 Through TWRP & then immediately flash no-verity-opt-encrypt.zip get rid of the message?
Thanks
Hi everyone,
I tried to update my rooted Pixel C with Android 8 and TWRP 3.1.0.0 from August build to September build with FlashFire.
All of the following have I done on my Nexus 5x as well and it worked as a charm there.
Therefore i dl'd the corresponding zip-file from google dev page and started the update with FF. It said to me it can update the boot, system, recovery and vendor partition so I unchecked the recovery partition only to keep TWRP. I also told FF it should include SuperSU again to root the new Android.
After the update the device was unrooted, so i tried to start into recovery to install superSU manually. But TWRP was gone and i get everytime the android on the back with the text "no command".
Therefore I tried to flash TWRP with NRT again. But after the flash the device always starts into TWRP and Android isn't starting anymore.
I can use NRT again to flash Android without loosing my data but than TWRP is gone again.
So either the device always starts into TWRP or I have no recovery installed.
Anyone an idea what i can do to flash TWRP again and to fix the boot order or whats broken than?
Regards,
flattervieh
I don't have the C but here's what I would try. First, have your device booting normally with the stock recovery. Then use fastboot to boot into TWRP, not flash it. When it boots into TWRP then flash supersu. From TWRP then boot back into the bootloader and then flash TWRP with fastboot.
Flash the latest (beta?) TWRP. It allows reading the encrypted data folder.
Short notice, i'm still struggling with the problem.
In the meantime I tried the following:
1. I temporarely booted TWRP 3.1.0.0, with this version I was not able to encrypt the data partion (always invalid key) but I was able to see the system partition and I installed SuperSU. After that i restarted into the bootloader and flashed TWRP 3.1.0.0.
This led to the same phenomenon, that my pixel always boots into TWRP and not into Android itself.
2. Same thing as before but with TWRP 3.1.1.1.
With this version I was able to see the size of the data partition, but I was also not able to read or write onto it. (Again invalid code) I installed SuperSU and made a device restart without flashing TWRP 3.1.1.1.
This led to a totally softbricked device with a boot into "no command" screen.
After flashing Android again via fastboot Android starts correctly and I can use the device but root is still not working.
Regards
I'm not sure why twrp isn't sticking. But the android on its back with "no command"is the stock recovery. To get into it simultaneously press and release the power and vol up keys. You might have to try it a few times as the timing can be very finicky. From there you can boot into the system, you don't need to flash the factory image and start all over.
Can someone tell me how I can safely update from open beta 9 to open beta 20 while maintaining root. I just want to make sure if there are any extra steps since open beta 9 was before the treble update. I am rooted with magisk.
also can anyone share updated twrp links or links for anything else I need if possible. Thanks
I heard that, I followed the guide in the development section and got and error when trying to flash it. I'm on TWRP 3.2.3-1 as well.
Yes, everything is fine, I have root. It took me a while, because of TWRP. The only problem is, that while you can get magisk, twrp will get overwritten by stock and I could not prevent it.
Process:
1. Install stock recovery (from here: https://www.androidfilehost.com/?fid=674106145207488252) in fastboot (fastboot flash recovery filename.img)
2. Install the new open beta
3. Download magisk on your phone
4. Install TWRP by codeworkx (from here: https://forum.xda-developers.com/oneplus-5t/development/recovery-twrp-3-2-1-0-oreo-8-0-8-1-t3729673) in fastboot and boot to twrp immediately.
5. Install magisk from within TWRP's first boot
6. After reboot twrp will most likely get overwritten by stock recovery, but we don't care as we have magisk already.
7. Profit.
@jazzgott so is there no way for me to reinstall twrp after updating? How will I update to new versions after?
@jccspeed
1. flash twrp via fastboot (pc, usb cable and phone and everything in need for this needed)
2. after flashing the recovery, turn off your phone, this is important.. do NOT boot your phone into the OS after flashing.. turn it off (chose power off with your volume keys within the fastboot mode and press the standby button once shortly)
3. hold volume down und power button at the same time until you see the "boot loader unlocked" warning stuff.. keep it pressed there for 2 or 3 more seconds. then let loose of these buttons.
4. you should now be in TWRP. congratulations.
if you now flash magisk, you will keep twrp as long as you keep magisk installed. you can freely boot into the OS and still have TWRP installed. How ever, if you don't install magisk and boot into your OS, your OS will overwrite TWRP with stock recovery.
forgot to mention: please use codeworkx pie twrp. its the one I have installed and have gotten into no problems so far.
@jazzgott @moeq123
Does this method erase the user data? I am encrypted and rooted(magisk). I want to preserve all my data.
@ajithpoison
at first I want to mention something important: always do a full backup.
if you unroot your phone (say, if you uninstall magisk using the uninstall.zip from within the magisk app itself and reboot) you should be able to update to open beta 20 via system update settings (where you need to choose a .zip file for the update.. so you need to download the open beta 20 rom from onceplus website).
(please verify that you are on stock recovery after the uninstalling magisk and reboot process. do this by booting into recovery with the power and volume down method. if you don't know how, google how to boot into recovery for your device)
This updating process should not erase your user data at all.
But be aware, that, if you want to go back to stable releases, you have to wipe everything.. so your user data will be erased if you choose to go back to stable releases.
if you want root and twrp back again, follow my instructions mentioned above.
@moeq123
Let me explain my situation in brief.
I am on the open beta channel. I am rooted(magisk) and I have the official TWRP and I am encrypted.
This is how I update everytime:
1. Download the zip
2. Reboot to recovery
3. Wipe cache and dalvik
4. Install update.zip
5. Install Magisk
6. Wipe cache and dalvik again
7. Reboot
This time, the above method will not work due to the compatibility thingy. I want to preserve app data. There are specific apps which I use and I don't want to lose those app's data. Previously I used titanium backup to take backup of app data. I am not sure whether backing up the app data and then restoring it will work since I am upgrading from oreo to pie. Is there any definite way to backup and restore app data after upgrading to pie?
I am summing up the method which I have to follow now. Correct me if I am wrong.
There are two methods which I know as of now.
Method 1:
The official method given by FunkWizard which involves deleting the compatibility.zip for which some users have reported ERROR 7.
Method 2:
1. Download Magisk & OB20 and have it in internal storage and switch off the phone.
2. Install stock recovery via fastboot.
3. Install the new open beta via stock recovery and switch off.
4. Install TWRP by codeworkx and boot to recovery
5. Install magisk from within TWRP's first boot
6. Clear cache and dalvik
7. Reboot to system and Profit.
(Will TWRP remain as a recovery after following all this or will it get overwritten by the stock recovery?)
@moeq123
Nevermind. I have got it to work without losing any data. I followed all the steps which were in the post by @funkwizard who put up the OP5T OB20 Official update post. It worked well except for one thing. The magisk manager did not show up even after installing magisk through the recovery. (I use BluSpark recovery). So I did a manual installation of the magisk manager apk and everything worked fine. I did not lose any data and so far no bugs.
I upgraded a couple months ago from 8.1 to 10. I ended up doing a full wipe ( or so I thought) through TWRP and flashing the 10 image. However, it seems that I somehow screwed up the encryption on my phone. I can boot the phone and put in my PIN to access and use the phone normally, but inputting the same 6 digit and my old pre-10 4 digit PIN into TWRP does not decrypt the phone and allow me to flash things. If I continue in read only mode in TWRP, I can flash but everything in my data partition has jumbled file names.
So my question is: Am I going to need to back everything up and wipe in order to fix this? Can I simply use Magisk to disable Force Encryption then decryp that way while keeping my data intact?
I would prefer using the simplest least painful way possible, but if I have to wipe to fix it then so be it.
Twrp decoding doesn't work for Q .. best to remove lock before entering TWRP
Also try "default_password".
Well I got impatient and ended up screwing up everthing.
Now I'm having trouble getting TWRP installed back on the phone. I have wiped everything, flashed the latest January factory image, booted to TWRP image, but when I attempt to flash the TWRP zip I get "failed to mount /system" and "failed to mount /vendor". If I boot back into the installed TWRP, I am not able to flash any other zips such as Magisk.

Disable your screen lock. Download twrp again to your pc. Put a copy of the twrp.img file on your phone as well. Fastboot into twrp, select instal, select image, go to your twrp.img,.select to install it to Recovery Ramdisk. You'll have to flash custom kernel and magisk again if applicable :good:
