I think OnePlus 5 uses File-Based Encryption, don't know if that works with Android encryption ( could be wrong) . You can try to add a passcode and it will automatically encrypt it. If that doesn't work you have to boot to fastboot and "fastboot format userdata" on Stock ROM. Will delete internal storage.

I think flashing stock OOS will also re-encrypt

How to enable encryption?

Hello everyone!
I am wondering how to enable encryption of my P9 Lite running Nougat B370. My phone is rooted, bootloader unlocked and TWRP installed, if that is relevant.
In the menus I don't find any option to encrypt my phone. So, anyone knows if it is possible?
If you mean data encryption, it is already encrypted.

You sure about that? Because TWRP can access my data partition without pin...
Is there any way to check whether disk encryption is truly enabled?

It's encrypted unless you unencrypted it with twrp but the latest update of twrp (nouget) lets you backup data unlike twrp on MM.

It's strange though, I've never unencrypted my phone with twrp. But when I boot into twrp my whole data partition is open for access without any sort of password/pin. Seems to me there is no encryption active.
TWRP can mount data partition, but it does not mean that it is able to decrypt it.
It can backup/restore or format it which is what usually what a TWRP do, if you install a custom ROM like LOS you will need to format it because the system can't decrypt it while stock ROM can do it.

What I meant by my post is not only that twrp can mount the data partition. I can also access all my files within said data partition.

How to (re) encrypt?

I had some complex issues flashing some roms and ended up having to format userdata. Now I am unencrypted and I have not been able to get the stock rom (from the official OTA zip) to boot. I was able to get all 3 of the custom OOS roms in the development section to boot, however when i go into settings and start encryption the green android logo flashes on the screen and the device does a hot reboot without starting encryption. I have tried countless things to boot the stock rom and/or get encryption to work including flashing the stock recovery on a custom rom, and the stock recovery asks for a pattern and mine doesn't work. I am totally out of ideas so if anyone has any please help.
solved: i previously did fastboot format userdata and it didn't work. I just did fastboot format userdata, system, and cache and the full ota zip installed, the security settings say it's encrypted, and i was able to decrypt with the stock recovery. Time to flash twrp and break more stuff!
Encryption
I believe the phone encrypts when you put a screen lock on.
I put a pin on mine booted in to recovery and it was encrypted, rebooted phone, removed pin, rebooted recovery everything back to normal.

Flashing stock boot.img in bootloader mode should encrypt the phone too.

Where or how can one extract/get the stock boot.img?
going to twrp wipe Then format data and typing yes will re-encrypt the device
Watch this

Thanks for sharing your solution. I found myself in this precarious position today. Solved with fastboot format... Thanks!

moto g4 plus rooted encrypted with password but twrp not ask for that

i encrypted my phone after i root it. It's running Lineageos. Encryption works, but if i boot in recovery i can enter folders but don't see any data. I can not mount data folder or add/install anything. Looks logic because it's encrypted, but i read somewhere that twrp will ask for a password when system is encrypted. I don't get this message.
Any suggestion how i need to do it correct? that i can enter twrp with pass

AFAIK you need a recovery that supports encryption.

i have twrp 3.2.1-0, question, how to start the ask password in terminal or recovery mode, if it is possible?
The only recovery i know which does support encryption is the 32 Bit shreps recovery. Do keep in mind that if you encrypt your device and use that recovery you won't be able to flash 64 bit roms since no 64 bit recovery supports encryption

Encryption with Alternative ROMS

Hi, ive been wondering why all those roms folks put out are unable to encrypt the /data partition.
Any rom i tried so far is soft rebooting after i invoked the encryption option. No encyption happening at all.
And if i do it manually via adb shell > su # vdc cryptfs enablecrypto wipe password somethingpw
I sort of soft brick the device boot until i whipe the data partion via twrp.
Thereof i am wondering why its broken in the first place and if theres a chance if folk will fix this over time or any 3rd Party Roms will be stuck w/o a chance to encrypt personal data.

I was facing issues with my LOS 15.1, afaik unencrypted. Then I flash stock Oreo Feb using Mi Flash tool, with option 'clean all and lock'. Then I root it with magisk and flash LOS 15.1. The next thing I know, my phone is encrypted

Clean install, i.e. wipe all.

Thank You, for confirming that Encryption works, i was almost at the verge of returning the phone.
Got it to work now.
....
The tldr of all i tested and messed around with is:
If you whipe Data trough twrp, with the special dialog where you have to type in YES. which folk reccomend to use to remove encryption,
will mean you brick the encryption and requires a re-flashing of the stock rom.
Secondly if you only go into advanced whipe, Art, System and data and then install a rom, it should say 'decrypted with default password'
Which is a dead give away that encryption might going to work just fine, rebooted into bootloader w/o into system, installed gapps pico, (eeh) and magisk, which also mentioned something about encryption as the log ran trough. Then rebooted into system, and now it says encrypted. And i can set up a boot pin/password before it fully boots. GREAT!
Soo.... If it says decrypted and won't encrypt, you have to flash stock, check its encrypted. Then install costum rom without removing encryption.
Once you removed it, its back to stock rom for new a /data setup/encryption.

Mi A1 Forced Encryption

I'm sorry if this is posted again but I can't find anything about my problem.
My Mi A1 in unrooted.
I had installed gcam without rooting it to continue receiving OTA, after the latest update I wanted to disable gcam. During the process the application unlocked the bootloader but didnt lock it again.
When I disabled it after the reboot my phone did a factory reset and enrypted itself. I want to decrypt my phone so I used some ways I found on the internet like:
Simple factory reset.
Locked bootloader.
Factory reset again, even though after the lock it did it itself.
Flashed fastboot stock rom.
Flashed twrp read only, wiped system and flashed fastoboot stock rom again!
Still the phone forced encrypt itself after every way I tried:
For gcam I used this way: https://forum.xda-developers.com/mi-a1/how-to/tool-google-camera-root-magisk-enable-t3747585
I didn't check the thread because I already had the app to do the installation.
For fastboot installation I used this: https://forum.xda-developers.com/mi-a1/how-to/ota-official-fastboot-image-n2g47h-7-12-t3728929
EDIT: What if I unlock the bootloader with MiUnlock and relock it via fastboot?
Phone is encrypted by default. Why would you want to have it decrypted? But if you insist.. you have to install magisk, disable forced encryption and reformat data partition in TWRP.
Locking or unlocking the bootloader after May update wipes your data, this is normal for Android and now our phones.
Encryption is default, it would have been encrypted before the wipe as it is now after the wipe, why do you want it unencrypted?

Thank you very much, I never experienced this again after unlocking so I thought it was because of the encrypt, I hadn't checked if it was encrypted before the wipe and I assumed it wasn't.

I didn't know the phone was encrypted by default.
Thank you for the possible way though.
Yeah, it is encrypted by default and hw encryption is used. So don't think that it can affect your performance in any way.

After reformatting data partition, do I need to do anything else?

Keep Magisk installed, otherwise it will probably get encrypted again by stock boot image. Not sure, I didn't try it.. I want my data secure.
