Encryption on the 5X?

Hey guys, I unlocked the bootloader, flashed twrp and root. Then I proceeded to do a fastboot format userdata. But after the boot the encryption was still there. Now I am running PureNexus latest build along with ElementalX kernel. I would like to remove encryption when I will be flashing another rom, How do I do that? Do I simply need to do a fastboot format userdata? Will I lose Twrp and root if I do that?

If you format user data and then boot with the stock kernel it will just re encrypt the device.
Only way to stop this to format usersata and then BEFORE booting the device flashing a kernel or custom rom with force encrypt disabled.
Keep in mind the installation instructions that come with your custom ROM or kernel though. Some require you to be on stock before flashing.
I would generally consider dirty flashing a different ROM over purenexus a bad idea, so you best revert to stock, format user data to disable encryption, do a factory reset then install the new custom rom.
You will lose everything though and have to start from scratch. You may get away with using titanium backup for backup and restoring apps if you know what you are doing.
If the ROM has a kernel with force encrypt disabled then you just flash the whole ROM through fastboot and boot it. What ROM are going to try?

Someone told me on reddit to just simply format data using twrp and that it will remove the encryption and wipe my whole internal storage. Is that correct?

I believe it does just that.

How to enable encryption

I am currently running a decrypted MM stock build on my 5X.
I want to upgrade to Noughat and then re-decrypt my phone. I think that flashing the factory image is the best way to do, but first, how can I re-enable encryption, so nothing bad can happen while flashing the factory image?

Just backup your data beforehand.
Flash factory image will format all your data, so the next time you boot up the device will be encrypted because encryption on by default in stock ROM.

To turn on encryption do these....
Go to settings then in security select Encrypt Phone,anyways there will not be any error in flashing factory due to decryption until and unless you have a bad config of fastboot adb etc or have a bad usb cable..if you want to decrypt again in Nougat I think you know how to..flash Elemental X/ Franco / some kernel with force encrypt disabled then go to fastboot mode and wipe userdata.

You're trying to do too much. It's pointless to encrypt, upgrade to 7.0, then decrypt. Factory reset and wipe system, upgrade via fastboot, flash SuperSU or a modified boot.img to stay decrypted, then boot up. Update your adb and platform tools before all this.

I agree with the other posters that there is no need to encrypt, but if one were to encrypt, this doesn't work if you have TWRP installed, it just hangs on reboot.
Best way to re-encrypt is to install stock boot.img and let it encrypt on its own.

if I wanted to save my data partition & update it to f2fs, would an adb backup before the format & restore after do the trick?

Id recommend to use magisk and phh's systemless su.

for data partition, just do backup using Titanium and restore afterwards,
for internal storage, use adb pull /sdcard (or /storage/emulated/0 ) to pull the files to your PC and just push it later
you also can use TWRP backup for data and restoring by choosing "rm-rf" method in the setting

Hi @Scronix,
I did wipe "Data partition" but did not do factory reset. Do I need to wipe cache & dalvik as well to get rid of encryption issue?
Also, I can first restore my backup from google account and take nandroid backup before processing to flashing su right? So, only extra step in original instructions posted in pinned OP3 thread is to do factory reset after installing twrp.

Sorry for noob comments. This is first time I am experimenting with my device and want to proceed cautiously.

What the magisk does and can i use it in any other way with rooted device?

Ok so I flashed the SR1 joint. It was working for a couple days but now it says "theres no su binary installed". Can anyone tell me why this is happing??

i strongly recommend A factory reset, also do not restore google backup for best result Also the factory reset s to be done by TWRP not stock and install SuperSU Before Booting into system

Thanks everyone for help. I was able to root after updating TWRP to official 3.0.3 and following guides.
I am still new to tinkering with my device. I will try magisk and system less su soon.

Downgrading Oreo to Nougat OnePlus 3

I'm running Android Oreo on the Beta line. I've felt that Camera quality used to be better in Nougat, and occassionally phone heats up with Oreo. So I'd like to switch back to Nougat. But I've seen a couple of threads mentioning about a potential data loss(whole internal storage getting wiped) and needing to install a rollback build before installing a stable Nougat ROM. Could someone shed some light into this? Is flashing the rollback build really necessary if I can flash the stable OOS 4.5.1 via TWRP? And, would I lose data in internal storage during the procedure? Thanks in advance.

I checked the thread and noticed that it's all about installing via the stock recovery. My phone's bootloader is unlocked and I have TWRP installed. So my question is, do I really need to install the rollback build? Can I not directly flash the 4.5.1 zip file via TWRP and be done with it? Or is there a purpose to installing the rollback version? I mean I read in that thread that after installing the rollback version via stock recovery, a factory reset should be done(which would erase the whole internal storage I assume?) and then the 4.5.1 zip file should be flashed. If I could use the advanced wipe option in TWRP to wipe the cache, data and system partitions and install the 4.5.1 zip file, do I need to go through the tedious procedure of installing via stock recovery, which would potentially erase my whole internal storage?

Why would OnePlus provide the rollback build if there are other reliable methods of downgrading?

I think rollback version is for stock recovery users and data loss + . And if you decrypted your data already downgrading is just flash zip in twrp and no data loss but you keep decrypt.

You mean the dm-verity thing? So it will be fine if I flash the Nougat zip file and install SuperSU binaries via TWRP to fix the dm-verity issue? That's what I've been waiting for as an answer. Thanks.

Can I stay encrypted when making a clean upgrade to OOS 5.0.8?

I am currently on the last open beta OOS, rooted with supersu and twrp-3.2.3-0. I know that i need to make a clean install of 5.0.8, so i shall wipe data/system/cache/dalvik, flash the latest 5.0.8 full zip, then reboot to recovery to flash magisk and then finally reboot to system.
My concern is - my phone is currently encrypted. Can i simply update as planned above, or do i need to take any additional steps to remain encrypted or go to decrypted state.
What could be the advantages of remaining encrypted or going decrypted?

Since you are on OOS (though beta), flashing 5.0.8 should not affect your encryption status. Your plan is ok.
Encryption is related to security. Decrypted means lesser security though I have no idea by how much. It is your call.

Yup, switching betweeb Beta to stable OOS will not affect encryption in anyway. Encryption will only be removed IF you manually format your data partition or the recovery does it for you.

Thank you. That was helpful. So in my case, i would have to erase data partition using TWRP to update from open beta to OOS 5.0.8, so the partition would get decrypted. But then i believe clean flashing the 5.0.8 zip would re-encrypt the data partition. Is my understanding correct?

No, when you "wipe data", it doesn't remove encryption. When you "format data", it removes encryption. I hope the difference is clear enough for you to grasp easily.
all you need to do is, if you have twrp, make sure you have OOS 5.0.8 zip, Magisk zip, working TWRP image - available in internal memory.
Then you need to Wipe System, Cache, Data - Do not check Internal Storage/Memory. or simply Factory reset from within TWRP. Then flash OOS 5.0.8 zip. Once it's done, flash TWRP recovery image from within TWRP. At this step, make sure you "reboot" back to recovery. If you will reboot directly to system, it will replace twrp with stock recovery.
Once you reboot to TWRP, flash magisk and you are all set!

One small addl. info. After flashing TWRP, there is no need to reboot to recovery. Simply flash Magisk right after TWRP and then boot to system. Flashing Magisk at that stage prevents TWRP being overwritten by stock recovery.
EDIT: or you can skip flashing TWRP and boot back to recovery after flashing the ROM and then flash Magisk alone before booting into system. Either way, you save one step.

I successfully completed the clean flash from last open beta to 5.0.8 and have magisk 18.0/twrp 3.2.3-0. Going forward, can i accept a new OTA update say 5.0.9 directly, or should i have to flash the full zip again? also would the process change when going to Pie later on?

I always download the full OTA zip and flash it manually wiping only system and cache/dalvik partitions, and I never had any issues whatsoever. Sure you will need to reflash magisk since your kernel and firmware will be flashed again.

Since you have Magisk and TWRP, the OTA either will not download or if it downloads, it will not flash. So you need to download the full zip (usually, the full zip will be automatically downloaded when the update detects changes to your system ie. root) and flash it. So long as you use the same above mentioned method to flash the full zip, Magisk will automatically flash going forward and your TWRP and Magisk will be intact. When going to Pie, since it is a different version ie. from Android 8 to 9, you should wipe system, data, Dalvik and cache before flashing Pie.
