Strange Encryption behavior - OnePlus 3T Questions & Answers

Hello, i have a strange behavior regarding the encryption on the oneplus 3t.
Since i got this phone i always had encryption enabled and with every restart i got a prompt mid boot process to enter the encryption password.
Same behavior when booting into TWRP, yes, my phone is rooted and i'm running freedom os with magisk su so i can bypass safetynet.
For some last days i stopped getting the password prompt, the phone booted right into the os, i figured when choosing the reboot option it only soft resetted and still had the keys in memory.
Tried turning it off and on again, still no password, tried booting into TWRP, and no password.
When going into the safety options it says that the phone is encrypted.
Haven't installed any new applications lately, but i started using the second sim slot since i was on a trip, removed the sim and still no password.
I'll try and wipe and reinstall since new version of freedom os is out.
Does anyone experienced the same thing?
Maybe it's some kind of malware?
Was running Freedom os 2.8 that is based on 4.1.3 but will soon be running Freedom os 2.9.

XT1068 stock fw fde trouble

Hi,
I've got XT1068, updated to 6.0 Marshmallow. In the past, I got it FDE (full disk encrypted).
Few days ago I unlocked my bootloader to gain root access on my phone using http://forum.xda-developers.com/moto-g-2014/general/simplified-modifying-boot-img-t3317605
everything went as expected, but by unlocking it wiped all userdata, so I wanted to re-encrypt the phone (and the external SD especially). But now, encryption fails, telling me "encryption fails, you have to reset your phone" each time I start the encryption, ending in a userdata-wipe.
So I thought about going back to stock fw.
After locking the bootloader and applying stock 6.0 FW, I tried again to encrypt the phone, but I am still unable to do so.
Can someone help me giving some suggestions, how I can fix that behavior and (mainly) how to get some errors/debug shown?
When selecting "encrypt now", the green android symbol with black background is shown for 5seconds, then the phone reboots, shows the bootscreen with the M, then it restarts again (after ~30minute) and shows after another 20seconds the message that something went wrong encrypting.
Ok it seems that I found out the problem in my case by myself.
Instead of using mfastboot.exe -w to delete the data and cache partition, I used recovery mode to delete userdata. I did it twice, since the first run, returns some errors.
After reset, I started the phone and got the fresh-install screen. I skipped mobile and wifi networking and did not entered google account details. Then I restarted the phone and waited for ~5minutes and tried to encrypt - everything works. Everytime I started encryption without waiting for some time it failed.
I hope I can save someone else some time, since factory reset takes ~15minutes each time you do it.

TWRP and Encryption password problem (or at least a question)

I've now installed TWRP (of this flavor : twrp-3.0.2-1-oneplus3t.img ), and supersu after updating firmware to 3.5.3 on the 3t I received yesterday. It installs without problem. I've not touched encryption and I'm very wary of using TWRP at the moment, because it always asks me for the encryption password. When I initialized the phone after this setup, the only password/entry entities I entered were a) a 4-digit pin, and b) 3 fingerprints. They work fine.
When I try to boot to TWRP, I always am prompted for a password immediately. I have no idea what the password is, and have tried my known-to-be-correct PIN , no luck. I have tried hitting cancel, and then only if I agree to mount /system as RO can I enter TWRP without it trying and failing to decrypt everything which corrupts storage.
I've read the entire (TWRP) thread a couple of times, but maybe it was too late at night. I'm wondering if anyone can tell me what step I'm missing, or if I'm trying to do something that can't be done because of what was just said above (encryption isn't fully supported by TWRP yet?) , or if I just should know the password and let TWRP decrypt it. Finally, is there a way to just decrypt the phone while booted and is that even called for?
I'd like to use TWRP which seems fine in every other respect (well, I don't yet know if I can make a backup & restore, so that isn't fine), but am held up by the password entry at the start of each session. Many thanks for getting it this far and thanks for any help you might give.

I would start over. Get the stock recovery and flash it. Then factory reset the phone. Do not put a pin or a fingerprint at all after you have booted to the phone. Go straight to the bootloader and do the twrp flashing instructions. after you have flashed and i believe if you want to be decrypted you format data than flash supersu again. Boot into system and then back to twrp and see if that worked. I remember doing this on my nexus 6p but not sure if the kernel has to support the decryption. remember when you do a back up of your phone never never never back it up with pin or passwords or fingerprint. You wont be able to restore succesfully from my experince with the nexus 6p. make sure you back everything up before doing this and i am not responsible for any problems occured. and make sure you are on the latest update from oneplus. hope this helped

That's exactly how I did it the first time, without password, without setting up phone, and when it got to TWRP (the first time), I was presented with the password prompt. When I hit cancel it went by it, but then said it was decrypting (which I didn't want), and corrupted my storage.
When I reinstalled 3.5.3, I did the same thing again, and that time was not corrupted so I was able to install supersu. At this point I've entered some fingerprints and a pin. TWRP says it supports encryption so I'm wondering about where the password comes from.
Thanks for your quick response. I'm still awaiting some reply over in the TWRP forum as well.

Are you sure you had 3.5.3 the first time you did it?

Yes, it was the first thing I did. After receiving the 3t, I skipped over all the prompts (to avoid entering accounts, waiting for sw upds and to not enter passwords) and went to software updates and allowed the 3.5.3 update to occur.
Then I did the things described above.
-----
In the interests of my trying to understand everything I'm reading about 6.x and encryption. I'm getting the drift that phones with 6.x + are encrypted as a matter of course. Is that the case (or how do I tell if it is)? If it is by default encrypted, then is there a default password before you have entered any specific pin or swipe pattern , etc?
Another question: When TWRP asks for a password, what exactly does it want to do? Does it want to decrypt the data for it's own operations (so just a twrp-level decryption) or does it actually want to completely decrypt partitions? If so, why? Is that the only way TWRP can work these days with default encrypted platforms?
Thanks.

Flash stock recovery, install stock 3.5.3 zip, flash TWRP beta 3 and then SR4. I went through same problem and this got me in(would accept my phone password. )

Is that the TWRP beta 3 from the TWRP thread? I thought I saw it mentioned in there. Thanks.
I've done the rest once so will give beta 3 a shot before I resign myself to putting the whole thing back together. Not that big a deal I suppose. I finally realized (after reading quite a bit) that 6.x + comes encrypted and that all versions of TWRP don't handle it right, so I suppose there's no easy way around it. (I'm wondering about this link I happened upon: https://www.androidexplained.com/oneplus-3-fix-twrp-restore-unlock-bug/ )

Yes page 9 or 10 OP gives me a link
The solution for me:
I received this reply in the TWRP thread in Development from the OP:

Yes, that completely fixed the entire mess and thanks to everyone else for their suggestions. Funny that I never had noticed the word "password" in the security settings, so I tried pin.
Now I've got an encrypted 3t with working TWRP, makes backups, tried a restore and f2fs, no real changes from stock aside from adding TWRP, picking a password, etc.
This seems to happen when you've got the fingerprint method enabled with PIN or password for that matter.
My experience:
I update from Oxygen 4.1.6 to 4.1.7 with TWRP and something went wrong because the phone stuck in bootload for more then half hour.
I've reboot and it appeared 'Encryption Unsuccessful' and it locked my phone. I tried to go to TWRP and it required the password that was 'default_password' but after it not allowed me to mount data and it seemed that there weren't any data in my phone.
I couldn't wipe, format or install other rom because I received error like 'unable to mount X'.
I've solved downloading the Oxygen Recovery and with a USB OTG, flashing it on my phone (with 'mount image' in TWRP).
I rebooted in Oxygen Recovery and it also asked me the password. I've just pushed 'Forgot password' and it formatted my phone.
The phone rebooted without problems (and without any data :\)
Hope to be useful for someone else in my same situation
You can get back in, without loosing any Data.
Go to TWRP
Choose Advanced
Select Terminal
Type this commands:
Code:
dd if=/dev/zero of=/dev/block//bootdevice/by-name/misc
reboot
Use Android again
I encountered this problem after I updated TWRP to version 3.2.1-0.
I regularly update my rom with TWRP and had never been prompted to enter a pin/password before. My lock screen pin was not accepted.
Seems this issue is a bug in a number of TWRP versions. I fixed it by flashing back to version 3.1.1-2. You can download and flash from a list of historical TWRP versions in Android by downloading the official TWRP app, so I didn't need to mess around sideloading it. Rebooted into TWRP, straight in, no problems.

Same problem on one of my 3Ts, the other is working with the Oreo based TWRP.
Oreo based Red Wolf Recovery is working: https://forum.xda-developers.com/oneplus-3/oneplus-3--3t-cross-device-development/recovery-red-wolf-recovery-project-t3805416
These things are weird:
1. Why does one 3T work, but not the other 3T ?
2. Why does (Oreo based) Red Wolf Recovery work?
3. Why is OOS Beta 29 able to decrypt Data perfectly?
I assume it's a decryption related bug in Oreo based TWRP.
im stuck not able to get twrp to see any of my storage and i cant get into twrp twice in a row, so if i fastboot and flash twrp thru adb and then boot into twrp, it asks me for the password, if i hit cancel it just shows 0 storage. ive tried to go to adb sideload but it just sits there. I have the backup i made thru twrp before trying to update.

What exactly is it you're trying to do? What TWRP are you using? What ROM?
You sound surprised that you can't see your Storage when you haven't entered a Password to Decrypt? That is, after all, what it's supposed to do. What security have you set up on your phone? Did you have Boot time security?
With so little useful information to go on it's hard to help. I'd recommend trying Red Wolf Recovery in any case. It's magic at solving many issues.
Sorry lol what happen was I was updating to latest stable oos, and had standard encryption set up. I wipes caches, and flashed latest rom, then magisk and again twrp (which I should not have) and then my phone had a quick reset. From there it was locked with twrp, neither my pin or default_pw worked so I just formated my phone, after copying data and important things to PC. Everything is good now just had to waste my own time.
For those of you facing twrp encryption when you set a password on the phone, remove your lock screen password and twrp will no longer be encrypted.

Not so. I removed the password and TWRP still asks for a password.

Encryption unsuccessfull after going back to miui

Hello everyone, i have a Little problem, i'm actually on latest aex mod 8.1 and everytime i try to install a miui based rom (epic and masik) installation is going fine, boot too but i'm stuck with a message telling me that encryption was unsuccessfull a message pop ups to restart phone and perform a Factory reset to solve this issue.i hit the button, phone restart to twrp wipe automatically data i guess (don't really remember) and reboot and again the same message. I've never encrypted my device and twrp dosn't ask me for a password. I've only set a fingerprint with pin code to secure my phone. Still i could restore my aex backup with twrp.
Anyone could explain whats going on?
Édit: same error if i try to install RR 7.1 it tells me that encryption (not decryption) was interrupted and had to reboot to twrp and restore a back up. I'm really confused

Data encryption does not work

Hi, a few weeks ago I had the pixel experience and I tried to encrypt the data, when I clicked the encryption button, the device only restarted and was not encrypted. Today, I decided to format and install Lineage OS 17 to clean up the phone that was full of apps a bit, I try to encrypt and it gives me the same result. How do I encrypt the device?

Phone stuck in bootloader screen after enabling encryption

I recently installed the latest Arrow OS 10 sanders version on my phone, everything was working fine so I decided to encrypt it as I needed to install some apps from my work. I did it in the Security options in the OS, not using TWRP in recovery mode.
It's been 3 hours since the phone is stuck in the bootloop screen, it already rebooted alone once but nothing else. What should I do? Keep waiting more time or what?
Thanks!
Hello,
same over here:
If I use lineageOS (lineage-17.1-20200720-UNOFFICIAL-sanders.zip - see https://forum.xda-developers.com/showpost.php?p=83100891&postcount=24), the phone gets stuck in bootloader screen when encrypting the phone (I let it run for 12 hrs). The same applies to HavocOS.
If I use EvolutionX (EvolutionX_4.6_sanders-10.0-20200810-0503-OFFICIAL.zip - https://forum.xda-developers.com/mo...nt/rom-evolution-x-4-0-moto-g5s-plus-t4031813), the phone gets into a reboot loop, once I order it to encrypt.
I've also tried an earlier version of lineageOS (lineage-17.1-20200105-UNOFFICIAL-sanders.zip), which used to work since February 2020 - with encryption but without any hazzle.
Any ideas on that?
I've tried it with
twrp-sanders-r20.img (twrp-3.2.1-r21) and twrp-3.4.0-0-sanders.img (twrp-3.4.0).
What is also strange: even if I format the system/data partitions, the phone still has the Microsoft Exchange services installed (I installed them during this entire mess, since I'm required to use it for company access). I thought, I should have been removed by formatting the phone... not?
Thanks a lot.
