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.

MHC19J & Data En/Decryption

Hello all,
Seeing MHC19J being the latest update to 6.0.1, I'm tempted to flash factory images like I've done for previous monthly updates (system, vendor, cache, bootloader, radio). Giving all the discussion on MHC19J & twrp v3 related to data encryption, I just want a few clarifications before I go ahead and get myself into trouble.
Here's my current setup:
-Data/Storage Decrypted (formatted userdata using twrp v2.x after unlocking bootloader when I first got 5X)
-MMB29Q - Feb 1 2016 security patch level
-Stock Rooted with Systemless v2.67 beta
-Xposed installed
Here's clarifications I'm looking for:
- will flashing MHC19J automatically RE-encrypt data/storage?
- if so, is there any way to De-crypt it without wiping data/storage? This is important to me because I'd rather keep my phone decrypted for superior performance gains and I don't really have time to reinstall my apps and restore data via Titanium backup at the moment.
If there's no way to decrypt again without completely wiping data, I think I'd rather go with V version or stay on Feb update for now.

Flashing any factory image will encrypt your phone as soon as you boot into the rom. Make sure that after flashing factory images, you boot straight into TWRP and flash Super. I flashed every partition as the bootloader and radio are newer. I maintained my decrypt status on TWRP 3.0 after upgrading to MHC19J. Basically, do what you have done every month to maintain decrypt status and you will be fine.
Just do not boot into your system until you have flashed SuperSU.

Thanks. Did you use officially released TWRP v3 or the test version posted today?
Did you have to flash Su from OTG or the data partition was okay?

Did twrp(the version you used to flash J) ask for password for data/storage upon reboot from bootloader after flashing?

I always follow the above post without an issue. I flash the boot.ing also as supersu will patch the kernel when flashed. I used TWRP 3.0.0 and did not have a password prompt and retained unencrypted status. Biggest key is not to boot into the ROM. If you do... It's already too late. Data is encrypted at first boot

I used the official TWRP 3.0 from awhile ago. Being that I was decrypted already, official TWRP 3.0 has no issues finding internal storage when moving to MHC19J. No OTG necessary.

Thanks. Is it enough to just flash SuperSU before boot into rom? I read something like
> You need a custom kernel that doesn’t enforce encryption on boot up. So install custom kernel via TWRP. Erase data partition. Boot up.
> via: www<dot>reddit<dot>com/r/nexus5x/comments/3zctaw/need_help_decrypting/cylsdle
That is, do I need to flash a "custom kernel" besides that flashing SuperSU before boot into rom?

Nope. You can flash SuperSU 2.6x only or flash a custom kernel that has disabled "force encrypt." SuperSU also patches the stock boot.img and turns off "force encrypt." Doing either will keep you decrypted.

SuperSu 2.68
I have flashed the new 19J ROM (radio, new boot loader, system, cache & vendor partitions) I left the userdata partition as is, it was decrypted.
I have installed the latest SuperSu 2.68 Beta zip immediately through TWRP (3.0.0-1), Than I have rebooted the system.
After the first boot up, the system is ENCRYPTED! There is no option to decrypt the system in TWRP. It can see all partitions just fine.
Where did I mess it up? How can I decrypt the system without to format the data partition?
I always install monthly updates on the same way, I never had any issues..
thank you
----------------------------------
Update 1:
when I boot into Recovery and I push the "Mount" option I can see the following note
" Data successfully decrypted, new block device '/dev/block/dm-0'
Updating partition details.,..
... done
Successfully decrypted with default password"
When I reboot the system it still shows: The device is encrypted.
Something wrong with the latest SuperSu?
---------------------
Update 2:
I did the exact same thing with my wife's 5X. Her phone is still decrypted after the exact same manual installation. I'm confused. ...

Phone Requests Passwort after setting security to none from pattern

Hello!
Yesterday I installed Resurrection Remix Rom and it worked great. So I configured everything to my needs including setting the security to ask for a pattern on Restart. So everything is encrypted.
After a reboot the phone kept crashing and I tried to go back to my old system. Somehow I managed to set the security to none so I can revert to my old system. I then rebooted to Recovery but in Recovery it asked me for a password. I never set a password so I don’t know what to insert in here. I tried various stuff but nothing worked. I also can’t reboot back into the system without a password. It looks like my phone is still encrypted.
Is there any way how I can decrypt my files?
Can i "convert" my old pattern into a password and this will decrypt everything?
And if I am ok with losing my data, how can I just wipe everything and install a new rom?
Thank you for your help!

easiest way to delete all your data is via twrp, select everything in twrp wipe section and execute. your phone will be completely empty now. reconnect your phone to your pc and copy paste the rom and gapps and flash.

I was in TWRP and tried to Wipe just the Data and Cache partitions but it told me that it was unable to mount storage.
I thinkt that since don't know the password i don't have permission to mount partitions.

Have you reflashing the stock recovery and doing a factory reset? After that you can reflash twrp and delete data. You can try if that works.

So you think i can mount the data partition again after a factory reset from the stock recovery?
I will try to flash the stock recovery when i get home.
I suppose i have to flash it via fastboot?

I read it on xda that this process resolves the issue and yes it has to be done via fastboot in bootloader mode. Stock recovery is available on oneplus's website.

I just flased the stock recovery via fastboot and made a factory reset.
After that I could reboot back into the system without any security question.
Sadly, all data are gone, meaning it did also wipe the internal storage partition. This is a pity but I'm really glad to have my phone back.
Thank you for your support

That's what a factory reset does, it wipes /Data

TWRP asks for a password even if you set a PIN.
enter your PIN - it should work.
my phone is encrypted running sultan's CM and TWRP asks me for a password when I go in, and my PIN works

Restoring encryped TWRP backup, does it work after one flashed unencrypted ROM?

Hi all
Before I flash a test (unencrypted) 8.1 firmware, I would like to check:
Currently I run encrypted 8.0 OOS 5.0.4 and codeworkx latest TWRP.
If I backup with TWRP (first remove security) and then factory reset (and format /data)
If I next flash decrypted ROM, can I straightforward revert back to OOS 5.0.4 with same TWRP?
Someone who did so, please raise a hand.
Thanks for letting me know.

Encryption happens on boot, so if you back up was encrypted and you don't flash no verity after restore. Then it will re- encrypt

I am not sure I follow why data re- encrypt is needed upon boot for restored encrypted data.
Or do you mean decrypt and re-encrypt? I thought crypt was file based.
I was rather wondering if the restored 8.0 OOS backup has the keys and code and setup to read encrypted data files. Especially when coming from 8.1 which may have different parameters. I guess it does but wanted to know someone who had restored encrypted OOS TWRP 8.0 data after running decrypted 8.1 ROM. Have you?
But then again, I do not understand well and therefore ask.
Because: if I don't like the firmware with decrypted data, I want to revert back to original encrypted OOS including its data. Since it takes much time to get the hundreds of apps configured.

The boot image of the backup will encrypt the phone again. In short, yes you can restore and be encrypted on ,OOS again

[Q] Decrypting data partition using TWRP?

Hello,
Previously I'm on Xiaomi.eu Stable 11.0.5 based on Android 9, did backup on system and other partition except data partition.
I updated to Xiaomi.eu Stable 11.01 based on Android 10. Flashing done without problem. After first boot, PIN code I used doesn't work to unlock the phone. (yes, i forgot to disable phone lock before updating)
Then I boot to twrp, it's prompt for decryption PIN, after decryption. I try to restore system partition, but it lead to bootloop.
I boot to TWRP again, but now it doesn't prompt for decryption PIN and my data partition still encrypted.
Is there any possiblity to decrypt it on TWRP so I can backup it to OTG drive before I clean Install it?
Or there are any other method to decrypt the files cause I can still access the files as MTP devices.
Thank you very much for your help

@underd0g, try to flash the ROM, of which data you want to restore, dirty before. This may make encrypt key availiable.

Do you mean that I need to reflash the ROM previously I used?
Okay let me try it. Thank you for your answer.
edit: reflashing ROM fixed the problem

I´Hello I have the same problem,
Unfortunate flashing via OTG does not solve the problem.
Also I am not able to flash a stock rom via the mi flash tool

Hello, i don´t know wy but after several formats and installations it worked and I´m running now on 20-3-19
Thanks all
