I somehow got my filesystem encrypted when I flashed TWRP and rooted. When I try to boot into TWRP, I have to enter a password to be able to see anything or do any modifications. What happened?
I didnt have this problem on my Axon but googled.

I have no idea if this will help you or not but it will wipe data so your phone will be factory reset. Do at your own risk.

This is from the Thread @bhint15 posted ,
Hit cancel at the password screen, then go into Wipe and then do a factory reset by swiping. Then go back into Wipe and press the 'Format data' button. You have to type 'Yes', and it will take a few seconds. After that everything should work normally.

and the reason why ask for password is cuz Axon 7 Data/Storage is Automatically encrypted out of the box, that's why you don't or not going to find any sort of encryption data setting under Settings and That's the reason a lot of users here have issues trying to get back to stock or something similar.....
This may give you some insight.

For me it's the Axon 7. I like the bigger res screen, the upcoming daydream compatibility and superior audio and non-Apple like OS.
The Honor 8 dies seem to have a better camera, but I can live with that. Plus I have an LG G5 for when I want photos.
You just have to decide witch Frasier is more important to you.

Alright, I managed to be able to write to /system temporarily by formatting the Data partition in TWRP, then rebooting back into TWRP. However, after rebooting into OS and setting up my phone, I rebooted into TWRP and was faced with the encryption password prompt again! Does the filesystem just re-encrypt itself when you start the OS, or am I doing something wrong?

I gave up for now. I tried for 4 days to fix this. In the end I have 30 days to return the phone. Hopefully someone will figure out a work around for this issue. I really like using twrp. I have not read a comment on here of anyone being able to boot into system then back into twrp with out having to enter a password to decrypt. I hope someone out there can do it and they figure out a way to fix it for the rest of us..

When does twrp prompt for password? I just booted into TWRP and it didn't prompt me. Then I simply booted back into the rom. Never prompted for a password.

As soon as I get into TWRP it asks me for the password. I can continue into TWRP but I can't mount or modify the /system partition (it reads as 0b in TWRP File Browser). No idea how to fix, but I'm glad it's not just me having this issue.
As of right now, it looks like we are going to have to wait for custom ROMs for a fix, unless TWRP gets an update just for this. I saw a thread here asking users for info for final tweaks on a CM13 port to the Axon 7.

Which bootloader unlock did you do? I wonder, why would this not happen to me but happen to you? I am willing to test anything that needs to be tested.
You cannot fix that. Like DrakenFX said, the partition encrypts itself in the OS. You cannot disable/bypass this!

Auto-encrypted can be disabled but that's way, way out of my league, need to rebuild boot. Img with that feature disabled.
There are two different scenarios that will be in play here. Is the bootloader unlocked or not. If the bootloader is unlocked then boot.img can be patched with the zip from idlekernle that disables the dm-verity and fstab. You cannot do this if your BL is locked, because it will modify the signed boot.img that that provides root, and will not boot anymore.
After it's patched, the system will not encrypt after /data wipe and TWRP will access it without problem. The downside is no encryption.
For the BL locked crowed, the /data has to be reformatted after flashing new rooted boot.img. This image also enforces encryption so one way to solve this would be for @tenfar to provide us with signed boot.img that set encryption of as well as. Otherwise the TWRP will need a password to decrypt /data if it can't use the default_password. In this case you should be able to enter the same pin you have setup for lock screen to decrypt the main encryption key.
The system re-encrypts itself on every system start after factory reset or /data format because of the forceencrypt flag in fstab, so the pin will be needed as long as that's the case. While TWRP should be able to try to decrypt with "default_password" in case you have not setup any on lockscreen, this sometimes fails, so having a pin on lockscreen usually helps. The cause is most likely that /cryptkey is altered somehow and TWRP can't use it. Wiping /data and rebooting should generate an fresh /cryptkey. I have been able to just flash modded recovery while still on stock boot and backup the /data with no key.
/system should not be encrypted ever since it would make block level OTA impossible to do. Why TWRP is not mounting it or seeing it 0b is a separate question.

Well i have formatted my data maybe 30 times with all sorts of different recoveries and boot images. My original boot image is long gone so hopefully that isn't the key. I also don't use a lock screen, I guess I could if it unlocks the data, but I certainly wouldn't want to keep using a lock screen. Anyways I am done with the phone for now, will revisit it when someone fixes posts they had the decrypt PW issue and fixed it.

See if you can set the pin, go into TWRP and us it. If it works, go back to OS and remove lockscreen, set to none and then go back to TWRP and see if it still asks for one. Did you run TWRP in read only mode or did you swipe to mount as RW?

I assume you mean the lock screen pin? I set a lock screen pin of 1234, but "password failed, please try again". So that didn't work. Is there a different pin for the encryption?
***update
That sucked. I don't use a lock screen but after I tried the pin it won't let be go back to none for the lock screen. I was just starting to use this phone to, now its back to the old phone because I can't use a phone with a lock screen . So sad. Hopefully someone figures out a solution to all this security crap.
I'm having the same issue on B27. Do a factory Reset, then a Format, and after it boots to the OS, the data is encrypted again. I'd be somewhat ok with it but I'm not clear on how to install things like Xposed if the drive is encrypted? I assumed ADB SIDELOAD... but not through encryption.
If the answer is "I don't know" -- then can someone help me restore to stock B27. I have a locked bootloader.

Xposed should install just fine if you're getting the message in TWRP. Id you're getting the encryption message after the phone is booted and can't access the phone, then you need to format data, then install Xposed so you can use the phone.
Some zips like SuperSU zip will not be able to be installed when the partition is encrypted. Xposed zip should install just fine

But if TWRP cannot access the encrypted data, how can one select and flash the TWRP flashable zip that accompanies the Xposed APK? Is the only solution to sideload? I see the option in TWRP but I am not familiar with how to do it.
Hi
I am unable to understand the concept of Decryption. I have been rooting my phone since the time of Samsung S3. I currently own a 64gb Nexus 6p with build number N4F26T. I use the sticky guide given here to root my phone and install custom recovery.
Now I want to apply pixel mods, but they demand verity check disabled. When I go in the security of my phone, it says Phone Encrypted in Encryption. I have checked all of the threads and forums regarding this but there is no clear guideline.
Do I have to decrypt my data? If yes, how will I be going on with this process? I see the format user data command but I am on Nougat 7.1.1 so I think this is not applicable to me. But no where has it been mentioned that I have to decrypt any other way.
Any help would be appreciated as I have always received from this community. How will I go on about the decryption? Please help soon as I currently have no data in it so its easier to format it.
You do not have to decrypt your data to use those MOD's. To disable variety check all you need to do is install a custom kernel or rom that does this by default. You will not lose any data by doing this. If you wanted to decrypt your data then you would have to format the data partition on your phone. This would obviously wipe your data so you would need to make a backup first on your PC. Some people think that decrypting your data will give you a slight speed bump but I've tried both ways and haven't noticed any real difference. So far I haven't run into any reason that the data partition would need to be decrypted to install anything.
This is a Question, so you are supposed to post in the Q/A section, not General.
First, you can't just decrypt the existing data on the phone, you'll have to wipe the device first and then NOT allow the encryption to happen on your fresh install. Make sure you already have USB debugging enabled. You need to perform a factory reset to wipe the phone. Then transfer from your PC either SuperSU (zipfile) or a no force-encrypt custom kernel such as EX Kernel or Franco (zipfile) to the root of the phone (or both). You can do this with TWRP's file manager. Before booting for the first time use TWRP's "Install" to flash either SU or your kernel. Now you can boot to system and your device will not be encrypted by default. Going forward with any updates that include flashing a new boot.img you need to reflash SU or the kernel (before booting) to avoid encryption.
First of all apologies about posting in the wrong section. Secondly, I have already rooted with Supersu. So now all I need to do is format the user data and I will have decrypted data right? It won't again get encrypted, right?
Secondly, thanks alot for such prompt responses. I am unable to find the thanks button that used to be there.
Here is a quick review of what happened:
The phone was running well on Lineageos 14.1, encrypted with a pattern, with TWRP 3.1.1 as recovery. I’ve then been notified of an LOS update to 15.1 Oreo and got excited. Booted in recovery, entered my pattern to decrypt, took a full TWRP backup, flashed Oreo modem and firmware and dirty flashed (I know, bad idea) the LOS 15.1 zip.
It got stuck at boot logo. Even if I didn't have high expectations for it to work I just thought I would try the lazy way to see and use my fresh backup to restore in case of failure like I always did successfully since my Nexus One.
This time was different because as I rebooted in TWRP to restore, it didn't ask for my pattern. You guessed it, the data partition is encrypted, no access to my backup or anything on the external storage. I can mount data and see the weird encrypted file names but that's it. I tried different version of TWRP, but it never ask the pattern. Even the terminal command 'twrp decrypt *******' doesn’t work.
I then tried to wipe data and flash LOS 14.1 again but it gets stuck saying that android has no access to data partition because it’s encrypted and that I need to format. I pulled out my sim card and started to use my old oneplus one while waiting for the new version of TWRP 3.2.1.1 with the feb security patch support thinking it might then be able to decrypt but no luck still.
I can go without the phone for a while, I’ll buy another one if I have to because there is some precious data on that phone and I can’t make my mind that the data is there, I know the encryption key but I have no access to it. There must be a way, I just don’t have enough knowledge about how this encryption thing is working.
Any help would be appreciated, Thank you

Try flash codeworkx TWRP ...
it should decrypt your data partition ...

I had tried it when it came out and I just tried it again. No difference!! It looks like twrp doesn't even see that my phone is encrypted. I've read a lot and tried many different things and I'm out of idea. All of the people I've seen with this problem have given up so they could get their phone back and running by formatting the partition, losing their data. This option is not one for me. I'd rather buy a new phone hoping for an eventual possible solution. I know the data is there, and I know the pattern key...... I mean, there's got to be a way......
Hi guys, i'm stuck in Rock and a hard place here and couldn't figure this one out. I've installed CyanogenMOD previously but that was a while ago and different process. What happened is I installed LineageOS 2 days ago and everything worked fine except No Sim Card is detected so I can't make phone calls and log into my Google account to sync.
Hence to resolve the Sim Card issue, what i did is to attempt to flash Bootloader, System , Radio images but it didn't work when i try to flash and also install LineageOS zip file. And in order to try resolving Mount issue, I proceed to Advanced Wipe -> checked System, Data, Cache -> Repair and Change File System -> changing ext4 to ext 2 . This formated all my User data which includes the ROM zip file i needed to install and load. I tried using Nexus Root Toolkit to restore into stock but it says no Fastboot/ ADB detected. And my computer couldn't detect my Nexus 6p.
Please provide solutions. Desperate here.
@Psuche To fix the no sim bug in Oreo you simply turn off lockscreen security once and reboot. Your phone is probably boogered because you switched to a filesystem the 6p isn't compatible with. Similar thing happened to me switching to f2fs without compatible kernel. So hopefully if you have and can still boot into twrp can repair filesystem in there back to EXT4. Obviously selecting ExT4 instead of F2FS.

Thank you for replying Exodusche. But i have switched back to EXT 4 and finds the system formatted and user data deleted! Plus my computer is unable to recognize my phone while i'm stuck at Bootloop =( Talk about difficult situations. So i'm unable to test your no sim solution at this point. Need to retrieve deleted files or at least push files from Desktop to Phone.
Any ideas?
So, after a few months on Oreo I clean flashed DotOS Pie last night, got the whole thing set up and tried to encrypt phone. It now bootloops, but I can get to TWRP, which shows me a pattern to decrypt data, even though my phone had PIN lock. I did the trick to "translate" between PIN and pattern grid. TWRP shows me "data successfully decrypted, new block device: '/dev/block/dm-0'", but I can't mount /data (consequently can't mount /sdcard), though I can mount /system. TWRP's console shows "Failed to mount /data (Invalid argument)".
I know I can just format /data on the wipe menu to get rid of encryption, but since I don't have a backup of /sdcard, I would like to know if there is any way to get /data mounted again so I can backup my internal storage before formatting /data.
If it makes any difference, my TWRP version is 3.2.1-0, latest one available at twrp.me. I heard that 3.2.1-1 handles encryption better (even better than more recent versions on some devices), but it's not available on the official site.
--Other details that might be relevant, but I'm not sure:
1. I do have TiBu's backup on my computer, so if I must restore my apps I'm fine with it (though I don't have a backup of the whole internal storage);
2. I also have a Nandroid backup of /system, /data and /boot, but it's on the phone storage only;
3. Last, but not least, I have flashed latest Magisk just before encrypting the device.
I saw some stuff related to a no-verity encryption zip file to be flashed via TWRP in some discussions regarding other devices, would it be of any help in my case?
@anupritaisno1 sorry to bother you, but you're the one person to ask for help with TWRP on OP2. Could you lend me a hand here? Would your enhanced TWRP help in my case? I know one shouldn't restore backups made with one version of TWRP within another version, and also that the tempcache stuff needs to be set up to flash ROMs. My plan here, if this could help, was to see if your enhanced TWRP can successfully decrypt my /data and internal storage, then I would back up my internal storage to my computer and either set up tempcache or reflash official 3.2.1-0 to format data and flash the ROM again.
Thanks in advance.
