Hello,
I've just installed the new OOS4.0, and I also wanted to update the filesystem to F2FS:
I've managed to get everything working with twrp-3.0.2-1.28 (ext4 cache/system - f2fs userdata) but then, I enrcypted the data via the settings menu, and now the TWRP fails to decrypt (password invalid). I understand that this is some kind of incompatibility since if I try with the official recovery it decrypts without problems.
Since I still have to copy all my userdata to the phone and install everything, what should I do before?
a) Keep data encrypted and wait for a TWPR fix, and eventually flash with the official recovery if needed?
b) Reformat and keep the data unencrypted?
c) You tell me?
Thank you for your help.
This is the only reason why I am still waiting for a proper twrp first. Don't want to decrypt my storage, and move all the data from my phone to laptop and then back to phone. Too much of a hassle.

I can't answer your question, but can I ask how you converted the data partition from ext4 to f2fs? I have TWRP 3.0.2-1.28 and OOS 4.0 already installed, and was wondering what the best way to do it is.
Do custom ROMS such as CM14.1 and XenonHD support f2fs?
Now, if I'm on OOS 4.0, no root, stock recovery; how can i get F2FS?? Thanks!

Well, I have tested this method both on OpenBeta9/10 and OSS4.0-
MOST IMPORTANT - FLASH TWRP .23, .28 HAVE BUGS WITH DECRYPTION AND F2FS (TESTED AND REPORTED BY MANY USERS)
1.) Flash 4.0 through stock recovery for dm verity error or flash 4.0 modem + firmware through twrp, skip this step if u r already on 4.0
2.)Copy all internal data to pc and make nandroid backup if needed.
3.)Wipe data to f2fs and cache/system to ext4.
4.)As wiping all these partitions, decryption will be gone and rom will be wiped, flash ur OSS 4.0(I prefer Builds like Experience Rom - https://forum.xda-developers.com/oneplus-3/development/rom-experience-rom-v1-0-t3522259 OR HyperStock - https://forum.xda-developers.com/oneplus-3/development/hyperstock-t3521946 , this one doesn't tiggers encryption and dm verity error.)
5.)Wipe cache and dalvik and reboot.
6.)Setup and install DiskInfo app to check partitions.
I know this method is bit lengthy, but u will get as u needed, decryption and f2fs for data with no dm verity errors.

Well, u can try flashing stock recovery and do factory resets for 1-2 times.
I have tested this on ob9 and got f2fs without wiping storage( As told by devs)
If this method doesn't works, then simply unlock bootloader, flash twrp and decrypt data with fastboot or through twrp cos someday u have to decrypt ur data.
Grab a holiday or sunday, copy all data and backups.
Enjoy F2FS life. :good:

I was using OOS 3.2.7 official and yesterday I thought of getting OOS 4.0 on my OP3. And I did flash the Experience ROM via Twrp - 3.0.2-1.28, but I was still on ext4 file system.. And I was getting a dm-verity error.. Then I decided to change the /data file system to f2fs and reflashed the Experience ROM. Now Diskinfo does shows my file system as f2fs but how to get rid of this dm-verity error with this Rom intact as I've done the setup of all my apps that I had before...

Brother, as u have flashed experience rom which already contains 4.0 modem + firmware, then dm verity shouldnt pop up.
Try to download and flash 4.0 modem+ firmware again through twrp, if this didnt help then try Hyper Rom.
If nothing helps, then follow the procedure i mentioned, backup all apps through titanium backup and sync all google stuff, make nandroid if any thing goes wrong, download official 4.0 full zip, flash stock oxygen recovery and do a adb side load.
Then flash twrp and clean flash experience or hyper rom u needed and restore apps back with titanium backup.
Report if something goes wrong

I did try to do the last thing that you mentioned. I flashed the official 4.0 through sideload. And dm-verity issue did vanish. But I thought of changing everything to f2fs. So I changed the type of system, data and cache. And flashed the Experience rom. But then, a strange thing started to happen. I just couldn't save any screenshot or pics I click but I was able to install or delete apps. So, I again went to TWRP (was really a hassle because I had to delete everything on phone and change system and cache to ext4 leaving just the data on f2fs and then doing several reboots and factory resets to get everything working). And then I flashed Experience Rom and I'm back to square one with dm-verity...
Still, I'd try to flash 4.0 firmware + modem files explicitly. And then I'll report. Thanks for the info, brother. :good:
EDIT: I tried to flash the 4.0 firmware + modem files but no luck with dm-verity issue..
Btw, I've a question. What's the downside of having this issue besides having that splash screen of warning on every boot up?
Can anyone properly give instruction on how to install OOS 4.0 without getting dm error + F2FS?
there's a lot of instruction in other thread that making this confusing.

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 -

Hyper Stock - https://forum.xda-developers.com/oneplus-3/development/hyperstock-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, 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.
^thanks for the instructions

Thank you for root users.
But if you flash Oxygen recovery & Oos 4.0 via adb you have just to wipe all in Oxygen recovery and your partition data make f2fs ?
After flash Twrp and custom Oos build.
I read in many post for flash Oos 4.0 you must have Twrp modify 28 ? With the 23 work too.
The problem they are no solution for root user to format data f2fs and flash custom Oos 4.0 directly with Twrp ?
Many root users flash custom Oos 4.0 with Twrp 27 but don't format to f2fs ! Stay in Ext4 and that run great. Ex : Fos.

i used this method to solve the problem
On my phone what ever oos i install, 4.0, 4.0.1, 4.0.2, data it's formated to F2FS.
To remove DM-verity message it's easy.
Boot to FASTBOOT and type this commands one after another:
fastboot oem disable_dm_verity
fastboot oem enable_dm_verity
Now i'm on FreeDom 2.3 (oos 4.0.2) with twrp-3.0.3 x v.15 blu spark 23.01.17

For dm_verity, only the enable command is necessary, not the disable one.
It was like that in original post.
Hello,
My phone gets automatically encrypted which forces me to delete all the data and flash rom via sidelod,
Even after doing that on fresh install it gets encrypted.
I found a guide on youtube but it is for android N but i'm using OB25 Oreo
please help me to decrypt my phone. so that I can easily flash other roms
That is what we call force encryption. Magisk and SuperSU both disable this by default. But it really shouldn't be a problem to flash a rom while being encrypted. Are you on the latest Bluspark TWRP? When switching roms it is always recommended to fully clean install anyway.
Encryption is not a problem with custom roms: a data wipe from TWRP can't remove it because the recovery delete content instead of doing a format, like happens in other partitions (i.e. /cache).
Just to keep encryption.
In fact if you choose to require pattern at bootup, even after a clean installation that pattern will be required with every rom.
If you want to remove encryption the solution could be a fastboot format userdata command via PC, or going to TWRP > Wipe > Advanced Wipe > Repair or change filesystem.
But OOS forces encryption at first boot, so to solve it, you need to install OOS together with Magisk.
I suggest you to install Magisk v14.2 beta, because v14.0 has systemless hosts issues with OxygenOS.
As recovery, nowadays only TWRP blu_spark v47 and upper version is compatible with OB25.
Oxygen OS encrypts the phone.
On Settings > Security, allways show me <phone encrypted> , on my phone. Never got pin or pasword.. My phone works with no restriction.
hey ho
so i have been reading several guides here and i recently posted in some of the threads but i think maybe it'll be clearer for you if i go through the steps i've taken. My goal is a non MIUI - rom without all the garbage, plus i want the option of expanded display or whatever it's called to hide the statusbar and i also want a rom with built in dark theme for the menus (settings for example)
what i did
redid EVERTYING, from scratch, I.E. (TWRP was erased)Downloaded: nitrogen_global_images_V10.0.1.0.OEDMIFH_20181012.0000.00_8.1_global_159a03b105
i then flashed it with MiFlashSetup.msi (previously before this whole entire debacle i had miui_MIMAX3Global_V10.2.1.0.PEDMIXM_a9972483fb_9.0.zip)
i installed TWRP with TOOL_ALL_IN_ONE_1.0.9.4-NO-INSTALLER
i booted into TWRP
Chose to flash DotOS-v3.0-arm64_aonly-vanilla-20190310.img and it then proceeded to ask what partition to flash, i chose system.
i then tried installing open_gapps-arm64-9.0-pico-20190327.zip and it said something about insufficient space and or / failed to mount partitions so i mounted vendor and system partitions and tried again, didn't help. so i just rebooted and it is now in the boot animation for DotOS and just.... spinning it's wheels so to speak...
p.s. before i did step 1 as extreme as that was when i tried going into twrp it asked me to decrypt using a password, the password should be the one i chose at setup, in my case i chose PIN and that password was never accepted as the correct password in TWRP so i could never show the system partition, it was listed as 0mb.

To avoid this gapless error when installing gapps, first boot the GSI that you have installed, then go back to twrp and install the gapps. In my opinion, xiaomi.eu roms are better as a basis for GSI's, even because I've never been able to start a GSI using an official xiaomi rom.
The main thing is that your data partition is encrypted and you will need to format the data partition.
This may help you - https://forum.xda-developers.com/mi-max-3/how-to/b-guide-to-fake-rom-unlocked-bootloader-t3846891 (where appears china rom, china dev ... can be replaced by global rom - this process has to be done before installing the GSI of your choice and take care of the ARB.).

what do the acronyms GSI and ARB stand for?
premier69 said:

GSI - generic system image (in this case, the rom you download in .img format for installation via twrp - for example, DotOS)
ARB - anti roll back - which is a mechanism to prevent the version rollback of Android.
Always read the topics carefully and follow the step by step without changing anything, not to generate problems.
I flashed AOSP_10_Quack_Phh-Treble_v208 many times last night.
but always failed,bootloop.
My step:
unlocked + TWRP
1.factory reset + format /data(or not)
2.flash V208.img to system image
3.format /data or not,reboot
My phone showed Redmi-logo and dm-verity error,
and bootloop.
anybody successed?
Could Somebody teach me how to flash GSI?
Maybe to flash AOSP 9?
It's reassuring to see you have attempted multiple times to flash another ROM and haven't hard bricked your phone.
My guess is you need to flash the dm-verity remove zip file. I'm assuming you have selected AVB 2.0 in TWRP? That's all I can think of but I haven't tried anything as clearly I don't have balls as big as yours
I used these following steps from tvardero :
Flash stock
Flash twrp
Make a backup of system and data (to get back into stock if needed)
Format data -> yes
Flash GSI you want to
To flash another GSI or revert to stock you use your backup of system partition.
NEVER EVER RESTORE ANYTHING ELSE THAN SYSTEM OR DATA, softbrick imminent
I try many GSI-ROM
Most bootloop,even I format /data,disable dm-verity/AVB 2.0 (TWRP by wzsx150)
My steps is
fomat /data,reboot to twrp
wipe /system ,2cache and flash gsi.img(Maybe resize /system to flash gapps)
flash magisk
disable dm-verity/AVB 2.0 with TWRP by wzsx150,or flash disabler.ZIP
GSI ROMs had some different bugs,brightness control,NO mobile signal,
sound,nfc-sim support,googlepay ,bank app etc.,
Really nice to see some testings. I hope we have some some development for our devices
