All data wiped after Oxygen OS 5.1.6 update [rooted phone]

Hi,
My phone and all my personal data (4 years of photos, videos, and other app data) just got WIPED.
Here's how it happened:
* I was on OS 5.1.5 till yesterday. Had TWRP as my recovery and Magisk as my root method. Everything was hunky dory.
* Oxygen OS 5.1.6 hit my phone today. I downloaded the update and installed it. Before installing - it clearly stated that my phone will be unrooted by the update. I was ok with that, as I would have simply installed Magisk again from TWRP.
* After the reboot, I opened Magisk manager and saw that Magisk wasn't installed.
* So I did a reboot to recovery from the phone's reboot options (advanced reboot was ON in developer options)
* It did not boot to TWRP. Instead, I saw a stock recovery type screen (black background, OnePlus logo).
* There was a single text called "Decrypt" and a terminal type basic keyboard displayed on the screen.
* At this point I knew TWRP is gone and this would definitely be the stock recovery, asking me for my PIN, to decrypt storage.
* I entered my PIN and pressed ok. IMMEDIATELY after that the screen displayed the message - "Wiping" along with "do not turn off your device while this happens" or similar.
* I was shocked to see this, as all I had done was enter my PIN in a stock-looking recovery with the OnePlus logo.
* The phone rebooted, and lo and behold - I see the new installation screen saying "Hello" to me!
ALL MY DATA IS GONE. Without any fault of mine! I simply did an OS update, and boot to recovery!
PLEASE HELP!

So you went 4 years without doing a backup? I think your out of luck.

First, I am pretty sure all your data is gone absent some expensive recovery.
Second, when you took the ota, you went back to stock, which is why twrp and magisk disappeared. This is actually how the system is supposed to work.
I don't know what you did in the stock recovery to cause a wipe. You should have rebooted to bootloader and reinstalled twrp from fastboot.

is it possible to recover encrypted storage on an android? i have simply turned the phone off immediately on seeing the new install screen boot up.

This is exactly where it's just crazy wrong. It just booted up to a recovery, with a screen saying "Decrypt" and a keyboard! NO mention of the next step being "Wiping".. ! This is just plain crazy, if that's how its designed!

pretty much. was just migrating data from one phone to the next using titanium backup/restore.

How could 4 years of photos and vids be gone? The phone is only weeks old. Surely you have backed these up to a cloud or even a pc at some stage? If you habe data backup turned on, you should have all your apps ready to reinstall.
You should have booted into bootloader, flashed twrp and magisk after the update. The OTA will always resort any custom recovery to stock.

I just kept migrating it from the previous phones to the next phones. Google photos does have backup of photos and videos. But there was so much more: SMS, call logs, whatsapp photos (the ones which were unlinked due to being moved to SD card earlier), screenshots, voice recordings, telegram images/videos, google authenticator tokens, and many apps whose data doesn't get backed up as part of android/google backup.

I don't have answers for either question. You might have more luck posting in the OP community, or in the official firmware thread.

You have a rooted device with a custom recovery so how did you install those in the first place and not loose data then? That wipes your phone doing that. It wiped again because it was being unlocked and relocked that always wipes it. Don't claim this is no fault of your own your running a modified device so yes it is your fault don't come on here and play victim it's really annoying

Wants to go 4 years without a backup then mod his phone and claim it's not his fault he lost data ??? what a joke

That happened to me too, but I solved it because after I flashed stock and then upgraded to 5.1.6 I installed TWRP in fastboot before booting to recovery.

Surely you have those titanium backup files though still right? Just restore from that, sure you may lose a week or two but it's better than 4 years.

Android is supposed to wipe data only on unlocking the device. Once it's unlocked there's no reason Android should automatically wipe data.
It did not get relocked. It is still unlocked. How did you come to that conclusion?
Also, I root my device ONLY to install TitaniumBackup and Helium. I do not meddle with anything else being root (no ROMs, tweaks, etc.). Is it my fault that Android STILL doesn't have a way to backup everything without having to root your phone and install special backup apps?
How can the OS just wipe the data partition without user consent? With NO message displayed whatsoever. Just ask a password go on "Wiping.. please wait". What the hell.

Yes I could recover some data from the SD card of my previous phone. Not the TB backups though.
I really need a way to (a) image the phone so that I can possibly recover/pay for recovery in the future (b) recover the data from the phone
I did a little reading. Apparently forced encryption is something that Android Oreo comes along with. All the data files are now by default encrypted (at a file level not a partition level). It is apparently encrypted with some randomly generated encryption key decided by Android, and not the PIN you have set to lock the phone. The PIN is just associated with that key. I'm pretty sure that key got deleted as well when the device was wiped (I'm assuming it must have been implemented like that as a security measure). So I have a wiped data partition with encrypted files!

You knew the data partition would get wiped otherwise? I've been rooting for years and never seen such behavior

Take this as a lesson, always have a backup. Especially if you mod your phones

It did have consent when you took the OTA with your modded device and it said decrypt and asked for your password it was about to wipe. Again you modded your phone and didn't keep a back up this is no one's fault but yours

Yeah I always back up my messages, photos, etc.. To a PC before any type of flash or update, I use smsbackup and have it uploaded to Google drive also titanuim backup and move the files to PC and just back ur DCIM folder. Sorry for ur luck but we all learn lessons the hard way, and no u Cannot recover, but if u have ur old phone may still have the texts on them and use oneplus switch to move them over

I guarantee this post is from a troll, nobody is dumb enough to do any or all of the idiotic things the OP claims.

Got the (important parts) of my data back. It only wiped the "data" partition - which contained internal app data and sms/calls, etc. It did not wipe the "sdcard" partition (also called "internal storage"). Found this out when I was installing TWRP again (before going through the OS welcome process) to create a dd image of my device for possibility of a future recovery. Android file transfer (thanks to TWRP's MTP support) popped up and showed all my files on the sdcard partition. Immediately backed it up.
To all those senior members who're making fun of this, thanks for all the help, really. You guys were really helpful.

I think this is impossible.. First the phone didn't return to me the root message before updating like oneplus 5 and second point, if you enter the pin to decrypt your data in recovery it never do an automatic wipe i'm a bit confused on what you've really done, but for sure you did something wrong because updating system had never wiped anything

Well this is completely possible, I just had the same thing happened to me. It was exactly as OP described it (except it was OOS 5.1.7, and it did not even ask me to input a pin when I rebooted to recovery). Fortunately I had a backup, so it didn't impact me much but still, it is a very weird thing.

Thanks for being sarcastic about being helpful. Sorry we can't hold your hand and fix all your problems because your not responsible for your own actions of modding your phone and can't take the consequences when they arise. Maybe you should learn how some more things work and what can happen when you do this before you do it and don't backup your device ever

Can't use twrp on oreo, it's asking for decryption key

I updated to oreo but after flashing twrp I noticed that I can't use it because it's asking for decryption key.
How do I fix this? I found some post with a method to flash the rom without encryption but I'd like to keep the encryption if possible.
I think a factory reset fixed it the last time on nougat but last night my phone froze mid wipe which broke pretty much everything and took me a while to fix so I want to make sure this helps before doing it again

TWRP is not fully supported under Oreo. It can't handle the full disk encryption. I've read that it is possible to set PIN / password *before* TWRP is installed and then it would work with the pass or pin you set before. But this didn't work for me. And I think there is no point in using it. Backup / restore function don't work and there might be more functions do not work.
If it's for magisk, there is also a way to install it without TWRP and / or there is no need to have access to storage. Installer just patches the ramdisk and you're good to go in ignoring the errors.

So what are you using instead if you want to flash something? I found some posts saying you can get twrp working with the encryption if you do a factory reset and data format in twrp, that way you should get encryption that twrp can read but I've tried this several times and my phone refuses to boot every time, it's not even boot looping, it just stays on that blue honor loading screen and with the little animation in the text so it didn't freeze. If I then try to do a factory reset in stock recovery it stops on 99%, forcing me to reboot, it then starts over and jumps to 100 and when it boots up pretty much all apps are gone, even system apps and keyboard apps so you can't type. If I try factory reset again the same thing happens, stops at 99 and so on
Now I have to recover it through erecovery.
Yea, I patched stock boot in the manager instead

I didn't come in the situation to want to flash sth - except magisk. And I didn't want to try it as it gains no access to internal storage.
Boot screen takes up to 30 mins or more after formatting storage. Kernel encrypts it during this time. I cannot say if TWRP is able to read this encryption since it is hardware based. I think it is possible as TWRP should use same kernel on treble ROMs - as far as I know.
So... Just being very patient could make it - theoretically.
Let me know if it can :good:

Try removing pin/password in settings and see if it still asks for key.

It does. And I tried it already right after flashing RROS system image (treble) and before setting a PIN and / or after removing PIN.
Look here https://forum.xda-developers.com/honor-8/help/internal-storage-encryption-t3452737 for background knowledge about this encryption.
Only way to get TWRP fully working on our device is to remove encryption through formatting the storage. But the kernel will encrypt every time while booting and TWRP will not be able to access storage anymore.
With the Nougat custom ROMs this was not relevant because they were using LOS kernel not the stock one. Treble ROMs are using stock kernel - which is, of course, an advantage.
And I didn't get TWRP to work *with* encryption (with entering PIN or whatsoever). I hope anybody can and tell me how to do or what I did wrong
Also I want a (safe) way to use it. Specially as I know that it's use is not supported by OpenKirin Team it should be safe before I really want to use it.

You can Format Data (removes encryption) and edit /vendor/etc/fstab.xxxx and remove the fileencryption line on /data.
I don't have an Honor 8 so I can't check it, but this is how it was done on Mate 9/10 before we got TWRP with decryption on Oreo.
Of course, flashing a new firmware will replace fstab so you'd have to edit it again/restore previously edited one.
Edit: Also, for fun, default password for decryption is "default_password", so you could try that. It most likely will do nothing. This is done automatically when you have no password/pin set.

Oh ok, never knew it could take that long but I guess it makes sense. At one attempt I even waited 20-30min ?
I'll give it another shot when I got some time over.
But I just finished restoring everything from hisuite and changing back all my settings for the 6th time since hisuite don't save your system settings.
Do you know if it's possible to make a nand backup without twrp? Getting a complete nandroid backup would really help when you're not sure if the factory reset will help

Unfortunately there is no way. Only with HiSuite or sth else. If your device is rooted you can use TitaniumBackup. It can provide a more complete backup of apps, app-data and settings.

Hi.
I use the fstab mod and do a full data format in TWRP. After that the data partition decrypted, but FRP locked, oem unlock grayed and I can't do set my google account. If I want to set the google account, the process is start but the screen is turn to black (navigation buttons show on the bottom of the screen) and nothing more. Some seconds later its drop me back to settings page.
TWRP installed.
Bootloader unlocked
Rooted with Magisk
FRP locked
Stock recovery not flashed back because HWMT show FRP locked

Install a full package via dload method. Take an 'unbrick' guide from the guides section if you need. You can use a 'FullOTA' package for your region which you can download with FirmwareFinder by TeamMT.

oneplus6 seems damaged following a failed twrp restore

So here is situation.
Phone been running 8.x version of havocos for months, however I was never fully happy due to broken usb tethering and random lockups (blue light freeze).
I decided to work on the phone 2-3 days ago, this involved doing a manual backup of all of data/media, and a nandroid backup. As well as some exports of configs in tasker etc.
I then flashed OOS stock, and nolimits, discovered tethering was still broken (yet it works with same sim in samsung galaxy s7 and hauwei).
This was the only issue tho, everything else was functioning as expected, phone was still fast.
Then I needed quick access to something that was on my phone from havocos, so decided to do a nandroid restore, this nandroid backup had all partitions ticked. The restore I also had all ticked.
The restore failed with an error 255 during data restore, I googled and found out is a nasty known bug for 2 years on TWRP, this backup was done on 3.2.3, I know now is a newer 3.3.x where this particular bug with corrupt backups might possibly be fixed.
I decided to try and boot havoc anyway but it boot looped, so I then went back into TWRP, and restored the vendor partition which was skipped. As it stopped on data, still boot looped, but also now this created a device is corrupt error on every rom boot even on stock OOS.
I spent ages trying to fix this error and during the process, discovered my phone no longer can be detected in flash boot as a com device in windows so currently the phone cannot be used with the MSM tool.
Eventually I reflashed stock using a flash-all script from here, and also put back on twrp using that script, and noticed even more issues that were not there before.
1 - phone is now much slower, stock before booted in one second after first boot, now its way way slower. Over 10 seconds so 10x as slow.
2 - I think before was a cache partition but is now gone. Supposedly these arent a thing anymore tho.
3 - nolimits zip will no longer flash with an error 1, I did exact same process as before but simply doesnt work now, the twrp detailed log right before the error 1 says "Please install the latest Magisk!" which suggests its failing to detect magisk.
4 - camera app is way slower, and OOS feels slower, laggier in general than before the problem.
5 - MTP no longer works when phone is booted up, again this is stock OOS and even if phone isnt rooted no magisk etc. But still works in TWRP. Basically the device pops up, I can see internal storage, but the size information is missing, and is no visible files/folders.
From what I can see I think my EFS is fine, I see an imei number.
I did fix the corrupted device error using a reboot command someone posted in that thread, so that error is gone now at least.

Try to flash oxygen os beta version from the official download links, let it install the stock recovery, then boot into rom, finish the installation progress by just skipping it and then factory reset it twice from recovery mode.
after doing that and finishing the setup , try to take picture and see if its saves it to gallery ( if the picture delete it self try to factory reset it through recovery for 1 more time)

I think you have figured out whats wrong, it just clicked, and I went to post and found your post so sorry no reply yet.
Indeed the problem seems to be a lack of /data/media/0
I have multiple times wiped data, and twrp has been putting files directly in /data/media, I just discovered I Cannot even take screenshots, magisk cannot download modules as well.
So I guess the stock recovery creates this structure?
Pretty shocking that twrp doesnt fix this or even have an option to. I will report back and let you know how things go, thanks.

Issue still there after stock recovery reset, wow these phones are damn hard to work with.
Also it seemed to do nothing, no settings were lost etc.

So basically stock recovery even if I choose full wipe does nothing, there seems to be some kind of lock on the internal storage that anything made by one plus is refusing to write.
I wonder if this is due to the device is corrupt message I had before where it said the device can no longer be trusted.
I can confirm that files that are on there are now visible in file manager and root explorer. But file manager can do no writes. root explorer can create new stuff but cannot delete or overwrite anything there, gets access denied.

I propose to start over again following this guide, option flash-all-partitions.bat. Helped for me.

I already stated thats already been done.
I eventually got msm working. and that luckily worked.

@chrcol ..., but you've issues

In recovery, format data. Problem fixed. Wipe will never fix your problem but format will.

3a seems to have bricked itself without any modification?

I believe one of the security updates decided to install partially and prepare to install on the next reboot which came during a night out where the phone reached 0%. Now when I turn the phone on all I'm getting is "Cannot load Android system. Your data may be corrupt" Google/Sargo 10/QQ1A.200205.002/6084386.
My question is, is there any method that can get a dump of the user data? I would be interested in paying for a chip off type service to get the local storage back. I pretty much do not care if the device is ever actually usable again, I have other phones to switch to but there was a lot which was not cloud syncing on this 3A. A nand dump is worth more to me than the phone itself. I've read that Pixels are encrypted by default though so I'm unable to think of anything other than being SOL on it.
I'm pretty furious at this thing, it's left me with the wipe and deal-with-it ultimatum that I'm only used to seeing from toying with flashing devices yet all I did was swipe away the February patch notification 2 or 3 times. How can this thing really have just bricked itself totally stock? Don't they bother to check the battery level before auto applying updates anymore? Help! What the hell Google?
Edit: Or thinking about this more calmly - is it possible to flash only the bootloader or key partitions of the os without wiping the sdcard partition? I could care less about the installed app data, only thing lost would be Signal messenger history. But the user space partition is the biggie.

Afaik, you can change the default boot partition, as we have 2. Only one gets updated. You can do that in fastboot mode. Search google for an how to. It should be something like boot a or boot b.
Wish you good luck with your data. I can write tomorrow, i have to sleep now.

Can you still boot into recovery?
If so, and if I understand the problem correctly, you might be able to ADB sideload an OTA from there. Download the version you were on or the update after that from https://developers.google.com/android/ota#sargo to your PC, boot into recovery and choose "Sideload update from ADB", get ADB running on your PC and use this command in a command line window
Code:
adb sideload [/path/to/ota.zip]
which should apply it like a regular update without wiping anything. This is possibly your best bet.
Did you unlock your bootloader, by any chance? Then you might also be able to flash a factory image via fastboot, but you have to remove the "-w" in the "flash-all.sh/bat" file to avoid wiping the device.
I faced another issue and went through a lot of troubleshooting, which I wrote about here and it might be informative or relevant to some extent:
https://forum.xda-developers.com/pixel-3a/help/systemui-crash-loop-rescue-directions-t3997747
Everything failed in my particular case, though, but this might show you some other ideas I and other helpful people had, especially with an unlocked bootloader.

I think you can edit the flash-all script and remove the wipe from the script line. But I'd try sideload OTA First if you can

Bricked my OP7P - Can't decrypt data partition anymore

Hey Guys,
this could propably be posted in r/TIFU as well since I think I screwed up big time today -.-
I basically just wanted to update my rooted OP7P to 10.0.5 (EU) using the latest OTA - so I followed the usual steps as always:
Uninstall Magisk
Install OTA - No Reboot
Install TWRP retention script in Magisk
Re-Install Magisk
Reboot
This procedure worked fine the last 2 times an OTA was released but this time I'm not able to boot into the system anymore. TWRP is still in places but won't read the data partition anymore - it also doesn't ask for my pattern to decrypt it. Problem is that idiot-me of course didn't do a backup before (yea, I know -.-) and obviously doesn't want to loose the data on it.
I of course checked the forum and googled my ass of trying to find a non-destructive way to access the system but couldn't find anything fitting my scenario. So my last resort is to ask you guys directly: Did anybody ever encounter such a situation and if yes, how did you resolve it? Right now any support would be much appreciated
//Edit: Symptoms and current behaviour:
Boot into system (partition A) ends in the OP logo cirling endlessly
Boot into system (partition B) sends me directly to TWRP
TWRP doesn't ask for encryption pattern
The answer to TWRP's initial question (Keep System r/o) is not persisted
Fastboot/ADB are working (but obviously w/o access to /data)
I'm technically running a stock OxygenOS with Renovate ICE. I know technically its instuctions say to install the OTA directly from within TWRP and and then re-flash TWRP and Magisk but that wasn't neccessary the last times... one idea of mine is to just do that now and see where it leads me but I really don't wanna risk my data.

The bad news is once twrp loses access to data. The only fix is to format data and everything will be fixed.

So... you're basically telling me I ****ed up completely and my data is gone? Never was a profile picture more fitting than yours right now :/
What I'm wondering is that, from a technical perspective and on a working phone, the decryption takes place not during the boot but only after you've entered your code/passphrase/pattern on OS level. Meaning the system should theoretically be able to boot up to there without /data access. TThat's why I had the idea to flash a clean stock Oxygen from TWRP (no root), boot the system and hopefully be able to access the data this way. Respectively any encryption can be broken somehow, can't it? Even if it might take quite some time to do so this should theoretically be possible...
I mean... I definetly don't know enough about Android internals to understand its encryption mechanics completely but from a technical perspective it should be possible.... like the saying "there is no such thing as 100% security"

Dude try flashing the stock rom from twrp onto both slots by mounting an otg drive..or adb sideload(very slow I think..still worth a try if you don't wanna lose data)..stock rom can manage the encryption I suppose.
Encryption is an issue when you flash different roms(I think so..I am no expert,just my experience so far).
Breaking encryption is not like what you think..it might take ages to break using brute force (again from what I heard..I lost my data a lot of time flashing roms without twrp backup..nowadays I just backup my apps using tb coz restorings the apps is really a pain in the ass process)

The reason that format is the only answer is because when twrp does not ask for password. It believes you are unencrypted. What has happened is the file that store your password and encryption key is corrupted so any answer you give is wrong.

There's nothing you can do but format data. I've encountered this issue already.

You can try to salvage personal photos and videos using an otg drive (external ssd, hdd, sd card reader...), also back in 6t days I had this encryption problem twice, I remember that one time flashing the stock rom from the otg fixed it but I don't remember if I rebooted to recovery of the other slot.
Anyway, for the others, if he used DM verity removal and so decrypted data, he would have never face this problem again?

I just tried flashing the stock Oxygen yesterday but to no satisfying result... afterwards it just showed a clean default-structure on the SD. Long story short: I accepted the fate that my data is gone and learned a valuable lesson... first thing I installed after rooting was Titanium^^

As hard as it is to admit, you were completely right... I just lost 6 months worth of photos incl. my last vacation in Vietnam - fml.

For future reference, brick means a brick. Like, can't boot to fastboot/twrp/or use msmtool

In the recent OS (10.0.5 & beta 13) I think Oneplus they add something that prevent user from using the TWRP retention script. I always use this solution for lower version and have no issue but with both 10.0.5 and beta 13 have the same issue

damn, good to know if I ever install OOS again - I now switched to Havoc... even though I had to skip rooting it all together after I couldn't get Magisk running with the latest safety net changes (thanks Google -.-)
