TWRP encryption problem - OnePlus 6 Questions & Answers

After i wanted to install Android P, i got a bootloop. so i wanted to go to twrp but now my files are encrypted and twrp is not asking for a pin or pattern so i can't decrypt my internal storage files.
Now the biggest problem is that i just came back from a family weekend and i made a lot of pictures, witch i can't acces now, and i really want them back.
Now i can't install a new os or anything ...
Can someone please help me! i'm really despirate
(sorry for my bad english)

Try downgrading twrp , night get it to ask for pin

downgrading is never the answer. In fact, that will cause this problem to happen. Now i must ask, are you temp booting twrp or is twrp installed to phone.

I got this when I temp booted the mtp enabled twrp the other day, although it still asked for my passcode and said description was successful. When I rebooted the installed (official) twrp it all came back....

Now i am booting from temp twrp, before that i got the latest twrp installed

Bringing this back up... Did booting from temp twrp work? Ran into the same issue.

Temp boot and use the usb c to pull ur data from the device to a computer. After that you can wipe and start over. Unbricking guide available in the help section

Having the same issue. If I boot using fastboot TWRP I'm able to decrypt data. I did that and flashed stock OOS and the same TWRP version (BluSpark) that was used in the fastboot. But the folders are still encrypted. It's weird how a fastboot can decrypt it but a regular recovery boot can't. Is there any alternatives available?
I'm in the process of backing up my data before I officially bite the bullet.

Only way i know to get rid of this by removing the encryption on the data is to Format the Internal Storage !

That's what I did in the end. I just backed up my media through fastboot TWRP beforehand. Beats having to use the download tool at least

Probably the best way indeed. I think i'm gonna start disabling forced encryption to stop these kind of problems.

Rooted with ODIN, how to get a working TWRP now?

Heyo!
So.. I recently got the 930F and rooted successful with odin, but my question is now, how do I successfully flash a working TWRP without having all the issues ppl describe below the twrp thread for sgs7?
greetz
after flashing TWRP with odin, enter your new recovery.
Wipe everything, then flash the rest of the files. You won't be able to boot otherwise.
You must in Odin remove the hook at autoreboot.
And then manually switch off the mobile phone with "Home-Vol--Power", then start with "Home-Vol+-Power" and wait until the TWRP screen comes and then let go.

can I just re-root with a method with TWRP included without worries or am I gonna brick my phone?

Why would you suggest a full wipe? Is it needed?
I did the same thing... used CF-Auto-Root to root my S7 and noticed that I didn't have TWRP. So I just downloaded TWRP Manager from the Play Store and used that to flash TWRP to Recovery. It worked perfectly as far as I can tell, no need to wipe anything.
Unless I've missed something?

The full wipe will disable data & sd encryption, so you will not face any problem while flashing roms & kernals, or creating twrp backup.

I don't know if I'm too late, but this is what I did and it was the easiest way to get TWRP.
Go to the Play Store and download 'TWRP Manager App', when on there hit 'Install TWRP', look for the SG7 type for TWRP and choose the latest datedTWRP (People tend to get Recovery is not seandroid enforcing error because they use an out-of-date recovery image).
It will say there was an error flashing recovery and give the option to Reboot or Reboot Later, but it actually has managed to get TWRP onto your phone so just reboot there and then.
Boom you have TWRP; remember the first thing to do is Format Data.
Good Luck

Format data when I first boot the phone after the twrp-installation-restart? or before flashing rom/kernel?

Format Data after TWRP Installation because our S7 phone has dm-verity and you will not be able to flash zips and ROMs properly. Formatting will get rid of that verity encryption.
Another reason why to format data after TWRP installation is because as this method does not fully get rid of stock recovery and is left dormant, so formatting the data will let TWRP read your Data.

Nope. That is not part of the Data partition so the format shouldn't affect - IMEI No. is part of the EFS partition.
If you do come with any problems though, quote me and I'm here to help. But believe I'm telling you what even I did and I'm running ROMS and shiz now.

bricked, need help

it's a pretty long story but currently my system partition is wiped after it soft bricked, i also couldn't reflash stock roms with twrp so i tried to extract the recovery.img from the stock rom and flashing it over twrp to get the original recovery mode back to flash the update but for some reason it didn't work.
so now i can only boot into EMUI which keeps telling 'getting package info failed' meaning i can't update through it. i'm also able to reach the 'fastboot&rescue mode' screen but i know nothing about adb and even tho i watched 2-3 tutorial videos i couldn't really get it to work. all videos wanted me to boot up the phone and enable usb debugging which i can't. my phone was rooted before and i'm positive i've enabled it in the past but i'm not sure if it's still enabled or not, either way i'm not able to get it working.
is this salvageable?
i'd really appreciate some help if possible, thnx
nope. but even when i had twrp it wouldnt let me flash update.zip's
i still have fastboot screen so my guess is that i have to run it through adb, which i don't know how to do

i CAN boot to EMUI (but EMUI keeps telling me 'Getting package info failed', it tries to connect and download but from what i can tell on the screen the download never starts)
Ok. Ive tried running 'adb devices' but i cant see my device, if i type 'fastboot devices' i find one device.
Dont know if im missing something or if this even matters.
But i'll try flashing twrp with fastboot

TWRP is back!!
but how do i flash marshmallow with twrp? and what marshmallow file are you talking about, the one i mentioned above?
because i tried flashing these update.zip's with twrp before but it wouldn't let me.
i'm currently packaging the update.app files into a zip and moving it to the sdcard, that's the only way i can think of to flash these update files with twrp.
since it didn't work last time, i have my doubts but i'll give it a try

Ok, just for clarification, your model is frd-l09c432, right?

yes. can't remember how to double check but way back when i downloaded these update files i was extremely careful to download the correct files.
and they worked and been working since they were the newest version, so i guess that has to be my model.
EDIT: and it's twrp-3.1.1-0
yea now it told me corrupt zip, last time i tried i got some other error, think it was some error about writing to system partition.
U can also flash this https://drive.google.com/file/d/0BwXB-CJiljwpS1o4UXo5b1JlRjQ/view and after

Ok download this firmware B120 and flash via twrp https://www.androidfilehost.com/?w=files&flid=129477 after this go to reboot and tap reboot recovery.

i'm trying to backup everything i need before doing a factory reset and i have a problem.
first time booting up i get the contact names on call logs for a few seconds and then they disappear because the contacts are gone. if i restore my data partition in twrp and boot up the system again i get the exact same thing. i'm guessing the contacts are saved at least temporarily somewhere on the data partition, is it possible to extract them somehow? i don't care if i have to write them down one by one from a .log, i got some important numbers that are worth the hassle for me

If you synced the contacts already then you can from google contacts.
I know this is completely backwards, but i found a twrp backup i did on my broken systems partition before i tried anything else. Maybe if i can undo what soft-bricked my phone i can get them back.
I installed/flashed a magisk module for xposed and after that i wasnt able to boot the system any longer. Is it possible to somehow uninstall this module and get the phone to boot again? Or is the only solution to flash a new stock rom?
Edit: havent synced with google in a while

the backup of the boot partition made no difference. even after flashing the new rom and the boot after nothing changed.
but i just solved it, i found a magisk uninstaller and after flashing that the phone booted up with all contacts, photos, apps+data intact.
when i first posted here i had wiped the systems partition and didn't know i still had a backup hidden away in a folder, so i'm extremely grateful for all your help and patience.
i still think i'm gonna update to nougat and i'm using hisuite that came with the phone, do you recommend any other backup application? do you know if app backups work if i update to nougat from marshmallow?

For apps backup just download from playstore , because some apps are compitable with mm and some are nougat .so better to download again from playstore after updating to nougat.

Bootloop + Encrypted Data

So I wanted to try out LOS 16. I made a full TB backup and a Nandroid backup on TWRP. I flashed Open Beta 2 for the firmware and booted. Everything was fine, but OB 2 is not my thing so I went like planned and booted into TWRP to wipe and flash LOS. This was when it went downhill: TWRP no longer prompts me for a password and all my files are encrypted.
Even so I flashed LOS and it boot just fine but all my files are no longer there.
I will try to avoid a full wipe down. It's painful af, and since i got the 6 it's the second or third time that I'm at this point. I don't get it.
At this point all i want is to decrypt my data and restore my nandroid. Does anyone know how to achieve this?
Thanks in advance

if all you did was temp boot twrp on pie, temp boot twrp can not decrypt data. You have to flash twrp to phone then reboot to twrp. Second, twrp can not restore backups of stock roms. Third, to go back to any oreo rom will require a format data to fix.

I'm pretty sure temp TWRP can decrypt data. I do it all the time. Regarding the restore, I wouldn't know, haven't tried yet but I think it would work, had I been able to decrypt it. Whatever. Full wipe it is.

I can get TWRP backups to work just fine on stock OOS, but I follow a weird process.
1. Store backup on something other than the phone (I got a USB OTG SD card reader/writer - I use a 128GB SD card to hold my stuff)
2. Use a fastboot rom to flash the same rom as the backup was made on. They are in this thread https://forum.xda-developers.com/oneplus-6/how-to/rom-stock-fastboot-roms-oneplus-6-t3796665
3. After flashing the fastboot rom start up the phone and go through the whole setup process (I don't know why but it doesn't work when I don't do this)
4. Install TWRP. Instructions can be found in this thread https://forum.xda-developers.com/oneplus-6/how-to/guide-how-to-install-official-twrp-t3801558 don't just boot TWRP, actually install TWRP (it might work if you just boot TWRP, I never tried it so I can't make any claims that it works)
5. Move your backup back to the phone and restore it in TWRP.
I have done this probably 100 times by now and it ALWAYS works. It is just how funky the encryption is on the OP6 that makes us go through hell to do something this simple. Try this.

Downgrade from 9.0.2 to 9.0.1?

Hi, just tried to do this by flashing the old zip trough TWRP, but i always end to boot in recovery, maybe i'm doing something wrong...?
I tried this today and happened the same, i guess you have to clean flash to downgrade.
Also a tip, if you got stuck in recovery and yet cannot decrypt (doesn't ask for password/pin in TWRP), boot to fastboot mode, use the command "fastboot boot <the img file name for twrp>" so that you can boot directly to the img file from your PC. This way it will ask for your password.

You might try flashing again when you get booted back to TWRP. That way, you can get 9.01 flashed to both slots if it's not already. No guarantees, but it's worth a try.

Can you link me to the exact fastboot rom you flashed? Some said I have to use the downgrade zip from OnePlus to Oreo 5.1.1 then only upgrade to 9.0.1. The OP of the fastboot rom said the rom is not for downgrading.
Did you downgrade to Oreo first or directly flash the 9.0.1 fastboot rom?

I've wiped everything, then downgraded to Pie directly, but I was in a slightly different situation (only fastboot available).
Just to be sure flash the Oreo one and then upgrade to Pie.
With the whole A/B partition layout it should be easier to downgrade too right?

No OS installed in TWRP

Hi guys
I was trying some of custom rom on my OP6 and I wanted to go back to Oxygen OS. So i did a clean installation with system wipe and i flashed the last full OTA update. But since i can't boot to system anymore, TWRP always displays that there is no OS installed despite the fact that I've tried several rom . Is this the first time it's done this to me how can I fix it?

The best suggestion I can give you is to flash stock oos with TWRP, reboot to stock recovery, without flashing anything else, wipe data from stock recovery and startup system.. if it is working you can flash back TWRP and magisk if you need it
Just be careful because at your point is easy to lose all of your stored data

If you wipe system, then flash oos ROM, TWRP will think there is no os. You can just ignore and boot.
Wiping system then flashing any time will make twrp display "no os installed" it does this because it hasn't created files for twrp to check if you have a ton installed. Flashing twrp then rebooting to twrp fixes it.
Reboot to stock recovery?

Hi, need a little bit of support, since I'm new to this as well. I was in a working OOS open beta 25/28, but then I think I flashed the wrong zip (OOS 9.0.9?), and I was not able to boot to system. It kept going to "bootloader unlocked" screen and custom recovery. Currently in TWRP blu_spark 3.3.1-x v. 9.109, and it's showing me no OS installed when I attempt to reboot. I haven't rebooted to system yet.
All the folders in my /sdcard is gibberish... if I try to push a file to it, it says "Required key not available." I did remove all security/passwords from my phone before doing any updates/backups.
I completed a wipe cache/dalvik/system via TWRP, and flashed the OOS OTA stable Android 10 zip downloaded directly from OnePlus Support. Considering this situation, do you still think it's safe for me to reboot to system? Then how do I get to stock recovery from there--is that by holding down the buttons?

No, your internal storage Is like trash cause the last rom you flashed has older security patch than oos10. Your device Is now encrypted and wont boot to system. I Guess you have to erase all via MSN tool or fastboot signed rom. Even if you wiped what mentioned above, your problem still be the data.
Fastboot method?

Thank you for replying. I'm relieved that you know of a couple methods to try.
Is using "Format Data" in TWRP an option for dealing with the encryption??
For the MSN tool, can I use this one? Tried looking around, but it's unclear. "[TOOL] MsmDownloadTool V4.0 International (Oxygen OS 5.1.5)" https://forum.xda-developers.com/on...wnloadtool-v4-0-international-t3798892/page10
I would be more comfortable with using fastboot, but am I at any risk of having lost fastboot, or can I just turn off my device from TWRP right now and hold down the buttons to get there? Afraid to move out of TWRP right now, in case I can't get back. I do have twrp-3.3.1-18-enchilada-Q-mauronofrio.img that I can run from fastboot if needed.
By "signed rom," do you mean I can simply flash one of the zips here from fastboot? "[OnePlus 6][ROM][OTA][Oxygen OS] Mirrors for official Oxygen OS ROMs and OTA updates" https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244

I hardbricked my device about 10 times and i was able to recovery It even from a blank screen. Btw format data Will erase all your data but also the internal storage. About fastboot dont be afraid, go under twrp reboot section and reboot to bootloader. Then go under xda op6 guide section and search for mirrors for fastboot rom guide by Mauronofrio. He pushed my ass out the **** a lot of time.
P.s. Sorry but I dunno how to paste a link via xda app. Yes, ik! It's a vert newbie thing.

That's awesome, I'm starting to grasp how much of a genius Mauronofrio is, after so many people referencing his work.
In his guide, he says, "These ROMs can't be used to update or downgrade your phone but just to restore your phone, so don't use them to come back to oreo or to update from oreo to pie." This may be a dumb question, but how do I know which zip/OOS version to flash, when I don't have a functioning OS on my phone?

I talked with Mauronofrio in pm and he said me that you could solve your issue simply flash the ROM you want and format data after flash that one. Remember that your internal will be wiped but it would happen in any scenario we talked.
Magisk, boot img?

That worked! And starstruck that you were able to check that with him. I flashed Mauronofrio's fastboot ROM for 10.3.2 and it rebooted (WOW). I clicked through the Google setup pages and checked that my data and wifi worked.
I then went back into fastboot, booted M's twrp img, fomatted data, and then installed twrp-3.3.1-x_blu_spark_v9.109_op6.zip, rebooted into recovery.
Then I think I made a mistake, because I installed Magisk-v20.4.zip. It succeeded, but now I can't boot into system anymore. Is it too late to flash the 10.3.2 boot.img?

No. Just flash stock boot image if magisk broke something.

I ended up following the guide to Magisk Root without TWRP for OnePlus 6 Oxygen OS https://forum.xda-developers.com/oneplus-6/how-to/patched-boot-image-magisk-16-7-beta-t3818853 since it was referenced by Mauronofrio's post for having issues getting his TWRP to work with latest Magisk.
Someone posted a patched boot.img for 10.3.2, so now I'm rooted without TWRP. Priorities. Now all I need is for special characters and emojis to work Will keep an eye on other threads.
I'm learning a lot, thanks so much for all your help. You pointed me in the right direction when I was not sure what the hell to do!
