Hello,
I'm using LineageOS 15.1 with TWRP. Since some time I do not have to enter my encryption code when phone is going to recovery for updating LineageOS. This is strange because phone is encrypted. Did I miss something or is something wrong with my encryption?!

It is possible to have the phone encrypted but with a default password (this is how the photos comes when you buy it).
You can check if it's encrypted in Settings>Security.
You can add an on-boot password by setting your password again and requiring it for startup. Then you'll need the password to decrypt the phone in TWRP and when you boot the device.

Hello @BillGoss,
thanks for your answer.
My phone is encrypted and I have set a password. I do also have to enter it while booting. Just twrp doesn't want one when updating. That's the strange thing.

Do you get this screen when you reboot your phone?
Sent from my OnePlus3T using XDA Labs
Yes, I do when booting phone normal.
I also have to enter it when booting to TWRP.
But I don't have to enter it when installing updates through LineageOS Updater in Android any more since a while.

So if you manually boot into TWRP you get prompted for the password. Good, that makes sense.
I have never used the updater, but since a rom update only requires access to the system and boot partitions, which aren't encrypted, it's theoretically possible to do the update without needing your password.
But I expect that you get prompted for the password when the phone reboots after the update has been installed.

I have my 3t unlocked and twrp flashed, but every time I boot into it, it indicates not able to decrypt data partition. Even after flashing with sideload, the pin which I set in preinstalled OS couldn't unlock it. Tried to disable boot up pin didn't help me out. Any hints?
Thankc

It sounds like he just wants TWRP to be able to access his encrypted data, not to actually wipe and decrypt.
jcadduono said:
If your device isn't decrypting in TWRP, chances are you still have the old crypto key format from the 3.5.1 release firmware.
You can solve this by updating to 3.5.3 and changing your boot up password in your device OS's settings.
By changing your password after updating to 3.5.3 or newer, your OS will rewrite your crypto key to be compatible with TWRP.
You are free to disable your password after this if you don't want one, and TWRP will decrypt with the default password.

@zphou Did you do that stuff, like the TWRP thread tells you to?
Sounds like you need to factory reset. Thats how you remove encryption. Ive done it before on my other phone. Perhaps make a quick manual backup of the folders on your phone or use the splendid Huawei Backup app on the play store and throw that on your PC before resetting. You can restore apps to the exact state as before your reset. Encryption should be removed afterwards.

Yes. I followed the instructions and now with latest public beta, which is 7.0. I still can not access to data partition in recovery. Luckly, I could flash 3rd party rom with sideload, the only issue is not able to boot into system. So I have to flash the public 7.0 beta.
TWRP is asking for password. I've never set a password. Please help me.
Try password as " password" , it may work !

Tell. Me exactly what u did..
Try : default_password if this doesn't work.. Then m sorry my friend u have to format full data..
Its asking for the encryption password. The default password is "default_password" (without the quotes) try that. And if doesn't work then enter Bootloader (fastboot mode) and enter the following commands into CMD.
Code:
fastboot format userdata
Code:
fastboot format cache
Code:
fastboot reboot
This will unencrypt your phone and you'll be able to boot/enter TWRP normally.
Please do note that you'll lose ALL of your data from the commands.
Also, I'm not sure about this but you also might need to flash TWRP again.

How is this possible?
Firstly, if u cannot enter into TWRP, then how did you flash the ROM?
Secondly, even if you somehow flashed the ROM how does it do away the password error ?? Did it replace the recovery? Recovery image is not usually included in custom ROMs.

I know right!?
I was running out of options. i thought why don't i flash the last rom that was running on this device. i can't explain how or why. I flashed the twrp again and than the rom. i can't explain but it installed the rom. It worked.
So you froobs can't read the dm-verity warning on TWRP page and just flash the one damn zip that prevents from this.
And the problem is in Kernel and firmware
I had trust in XDA-members. But the faith is gone.

Wait, were you able to get past the twrp password thing without formatting just by flashing the rom? Why did you have to flash twrp again before the rom? Did you do a clean flash or dirty flash? Your internal drive was not wiped?
My problem is basically that I was unable to get into my phone so I deleted the 5 gatekeeper/lockscreen keys from data/system. Now I can only see the wallpaper and a blank screen that doesn't allow me to do anything. It doesn't let me allow me to set a new pin. TWRP is asking me for a password that I never set. I've been trying to figure out how to access my data without formatting, but I'm running out of options too..

Maybe he used SuperSu to root? I dont' see a dm-verity zip for that. You have to use the bluspark TWRP posted above this reply and set your password in the ROM through another app or through the system settings in that case. I had the same problem. Also, I could have used "default_password" but I didn't know that until after I did all the fastboot flashing...
Or do you know of another zip SuperSu users can flash?
The password which its asking for is the one which is our lockscreen password
OxygenOS encryptes our devices with the password we enter on lockscreen so to decrypt just enter the same password

That's the ticket
Just wanted to update my EX kernel with the kernel manager app, it reboots to TWRP and than requires password.
I've never set a password to TWRP and my PIN doesn't work. It also happened to my brother's 3T, that's so weird.
I would like to know if there is any solution that doesn't include factory reset or re-flashing TWRP.
Thanks from advanced, Lidor.
Update:
I tried to disable the PIN when you boot up the device. Now TWRP doesn't even work. It just shows the logo...
Guess I will have to re-flash TWRP... Just tell me if I am right.

Try reflash twrp to yr phone.
If you are on oxygen os twrp will take time to load (without pin enabled) as OOS uses f2fs format which is relatively newer format and allegedly considered better than more traditional ext4 format
So if twrp logo shows after booting in recovery then wait for sometime (can take upto 10 min)
I updated TWRP and now I cannot access my phone through the recovery. It asks for a password; I don't even recall creating one and then won't let me see my encrypted phone. So I cannot flash things or recover my data to my PC before I delete all my data. When I start the phone, the ROM says "Unfortunately, System UI has stopped."
How can I get my data from my phone?
Did you use the latest version of TWRP from here?

If not, use that.
If you did use the version and had the problem, then try the Blu Spark 8.61 version from here

Thank you for your help! You're such a ****ing star! I have access to my data and I'll be doing more diligent backup procedures moving forward. Thank you so much!
Basically, the phone would not accept my password to decrypt. I don't recall setting one. I looked around online for a long time and found that I could go into system settings and change the password, only that wasn't an option for me! So I got an app that allowed me to change the password without knowing the current password. That just created a prompt that requested my password each time I started up the phone but did not grant access in TWRP and of course I could not boot my phone because of the system ui error.
So, I installed the first TWRP package you recommended but it still did not accept my password and then I tried the second package and entered the password. It worked! I'm grabbing my data through TWRP as we speak and I'll see about fixing my system ui error from here... Thank you again!
Hi guys, I have a OnePlus 3T which I have been using since 2017 and it worked perfectly. But a few months ago it updated to Android 9 Pie and ever since then my phone has gotten far slower, keeps hanging on certain things and sometimes I can't even make a call directly from contacts. I have to click call then it seems like the call is starting up but then just freezes and cuts off. Afterward, I have to go to call history and make the call again and it works.
I waited a while to see if a newer update will fix this slowdown and issues but after 2 or 3 more Pie updates it's still unresponsive and crashes the dialer. So I just want to know if anyone can tell me where I can find a ROM for final Oreo version that is compatible with OnePlus 3T and the best way I can downgrade.
I tried following a guide already but I ran into issues simply flashing TWRP. I Installed the ABD drivers, unlocked bootloader and rebooted.
Then in fastboot mode, I tried to flash it and it seemed to work because in the ABD PowerShell windows it said "Okay" after I used the cmd to flash.
But when I reboot and go into recovery, I still have the default recovery options.
This is the first time I am trying to flash my phone and I'm only doing it because it went from a phone that ran super smooth to one that is barely usable...I mean Contacts and the actual Phone apps are hanging and crashing. It even crashes when I try to answer incoming calls sometimes. The phone keeps ringing and I get a message saying the program is unresponsive, giving me options to "wait" or "close"

Something you need to know: stock OOS will always reinstall the stock recovery when the phone boots into system.
So if you
1. Booted into fastboot
2. Flashed TWRP
3. Booted your phone
4. Booted into recovery
then TWRP got overwritten in step 3.
What you should have done after flashing TWRP was boot into recovery directly (use the volume keys while in fastboot mode to select that option then press the power button).

Thanks for the reply...and it got me a step further. But when it got to TWRP it starts at "Mount Decrypt Data" I assumed this was my phone pin...and when I tried that it opens up a cmd window which said "unable to mount storage" then says "updating partition details" but it sort of freezes then the phone turns off and powers on with the notification LED being "white" but the screen is black and the phone just stays like this for ages. Only thing I could do is hold down the power button to power down the phone and restart it. At least TWRP seems to have flashed because even when I go into recovery from the boot menu it goes to TWRP.

Personally I would not downgrade to Oreo. Pie works fine. The problems your were having could have probably been solved by simply doing a factory reset.
Since you've unlocked your bootloader, you've effectively done a factory reset. So try just booting the system and set up your phone again. It'll probably be fine now that you're doing a clean install.

Yea...I have done several factory resets in the process of unlocking the bootloader and flashing twrp. So it didn't fix the issue. The main issue is linked to "contacts" which basically freezes most times I try to make a call. It makes the call but crashes contacts and the "Phone" app. Which is stupid because that's the main purpose of a phone.
Also, another key reason for wanting to downgrade to Oreo is the ability to record phone calls. This is very useful to me and those apps stopped working with Pie I think.

If I was to go back to Oreo I would:
Download the full Oreo OOS ROM and backup everything you need onto your PC. Then in TWRP:
1. Do a factory reset
2. Flash OOS 5.0.4
3. Wipe>format data (to get rid of encryption)
4. Reboot system, which will also encrypt the data again and replace TWRP with the stock recovery
5. Use ADB to restore the data on your phone
6. Flash TWRP and restore your Oero backup.

In that case, I hope you've got backups on your PC because you're going to have to format your phone. TWRP>Wipe>Format data. You'll need to cancel out of the password screen to do the wipe.
Then reboot into recovery and use ADB to copy the files to your phone and flash Oreo.

I got my data backed up using some software called "dr.fone" but how do I use ADB to copy files to the phone?
As I said at the start, this is literally the first time I'm trying to do this. I never flashed my phone before and never used ADB or TWRP before.
I'm literally just following instructions in guides and forums. So please don't assume I know how all of this works.
Hmm. I've been thinking about your problem and I have some questions/suggestions.
1. What version of TWRP are you using? (I would use the latest one from https://dl.twrp.me/oneplus3/ )
2. Can you boot your phone normally? If so, try setting a new password and say Yes for secure start up. Then verify that when you reboot you are prompted for a password (Starting Android screen, not just the lock screen). If that works, boot into TWRP. Does the new password work?

I'm using the latest version of TWRP (top one on that list)
I can boot the phone, and it works obviously. But I was having serious issues and slowdowns after updating to Pie.
Changing the password didn't work...but doing what you said before and formatting the device and rebooting into TWRP seems to have worked.
It's recognizing the storage and I can choose zip files to install.
Do you know the last version of Oreo that was compatible with the 3T? I think it's either 5.0.8 but they may have released 5.1.8 for it...I can't remember and can't seem to find the info anywhere.

I would second the suggestion that you don't downgrade to Oreo. I was having the same issues you mentioned on Pie, but have since sorted them out. Pie is now running very nicely for me.
A good deep cleaning did it for me, even after a previous factory reset had failed to fix it.

Well, it seems like downgrading to Oreo is going to be a huge task. Because my research I need to flash some stock firmware before being able to flash Oreo again.
Which I tried, but for some reason, it's not flashing it. So now I need to download the latest stable version of Pie for 3T again?
Can any of you tell me what version that is?

But Bill has already given you the steps for downgrading if you want.

I decided to test downgrading to Oreo from Pie. And I learnt that it's basically the same process as upgrading from Oreo to Pie. Since my phone is unlocked and encrypted I had to remove the encryption using TWRP>Wipe>Format data: yes when going from Oreo to Pie and the same when going from Pie to Oreo.
So my process to downgrade is:
- Backup everything I want to keep from my phone.
- Flash OOS 5.0.8 full stock zip in TWRP. This completely overwrites the 9.0.5 firmware and system.
- Remove encryption: TWRP>Wipe>Format data: yes. (You'll lose everything on your phone)
- Reboot system (it re-encrypts the phone and replaces TWRP with stock recovery).
- Restored phone data, and so on.

One more thing that I'd forgotten about: you can run OOS Oreo on the Pie firmware. So if you still have the Pie firmware installed, just restore an Oreo backup and you should be ok.

I decided to test downgrading to Oreo from Pie. And I learnt that it's basically the same process as upgrading from Oreo to Pie. Since my phone is unlocked and encrypted I had to remove the encryption using TWRP>Wipe>Format data: yes when going from Oreo to Pie and the same when going from Pie to Oreo.
So my process to downgrade is:
- Backup everything I want to keep from my phone.
- Flash OOS 5.0.8 full stock zip in TWRP. This completely overwrites the 9.0.5 firmware and system.
- Remove encryption: TWRP>Wipe>Format data: yes. (You'll lose everything on your phone)
- Reboot system (it re-encrypts the phone and replaces TWRP with stock recovery).
- Restored phone data, and so on.

Do you have a link for the OOS 5.0.8 full stock zip with the firmware?
I downloaded files from these links:
https://www.getdroidtips.com/oxygenos-5-0-8-oneplus-3-3t/
https://www.androidjungles.com/oneplus-3t-flash-file/
But neither of them are flashing in TWRP.

I would second the suggestion that you don't downgrade to Oreo. I was having the same issues you mentioned on Pie, but have since sorted them out. Pie is now running very nicely for me.
A good deep cleaning did it for me, even after a previous factory reset had failed to fix it.

What do you mean by deep cleaning?. I tried hard reset but after using apps phone again became dead slow.
