TWRP 3.1.0 - wipes userdata and more

I install latest TWRP 3.1.0 version today.
All the user data, some apps (Waze, Gmail, Gmaps...), SMS were wiped.
I have RR-N-v5.8.2-20170218-oneplus3t-Official currently installed.
I reinstall some apps back.
After system reboot all seemed fine.... But after boot to recovery (TWRP 3.1) and than boot into system all was gone again.
It looks like every boot to recovery wipes user data and some apps...

Flash 3.0.4-1 again

Same problem here with 3.1.0.0.

I flashed 3.1.0.0 img with 3.0.4-1 and do not have the issues OP is describing.
Edit: stock Open Beta 3 rooted.

I did... and restore system from backup BUT some userdata is gone forever...

Apparently, the official TWRP 3.1.0-0 for OnePlus 3T only works with Oxygen OS. So far, only users using custom ROMs have reported issues with partition wipes after flashing the latest TWRP.

Happened to me on OOS. Went back to 3.0.4-1
Sent from my OnePlus 3T using XDA Labs

It was updated to 3.1.0-1 try that

I suppose this of because of the official TWRP 3.1.0-0 is not using the backported F2FS driver. I'm using EXT4 filesystem on data partition so therefore I'm not experiencing any data loss.

Was on RR 09.03 with OB3 firmware, it completely destroyed my phone. Bootloops, impossible to go back to recovery, when in recovery, impossible to see files to flash them, even going back to 3.0.4.1 did not solve everything, reinstalled Freedom OS but had screen total freezes.... Had to go through the total disaster recovery utility, and I am still re-installing everything...
TWRP 3.1.0.0 ate 4 hours of my flash-addicted life... FML !!!
**STAY AWAY FOR NOW**

Blu_spark 3.1.0 version is not affected by this, only the official.

Stock OOS 4.0.3 and TWRP 3.1.0-1 = ALL GOOD!

Can confirm. TWRP 3.1.0-1 works fine. (rooted OOS 4.0.2)

I had at least two serious issues with official TWRP 3.1.0-1 and LineageOS:
1.) After a first flash attempt via fastboot I was no longer able to unlock my phone with my PIN under LineageOS.
2.) When booting into TWRP I got a black screen - unable to do any useful.
3.) After I could no longer unlock my phone under LineageOS I reinstalled LineageOS from TWRP 3.1.0-1. All looked fine until I rebooted from TWRP into LineageOS: TWRP obviously wiped my device and I was offered
the setup wizzard of LineageOS. All my setting were gone.
I had issue 3.) already with TWRP 3.0.3-1. I immediately reflashed TWRP 3.0.4-1 - the currently only working TWRP version.
I would like to add that I had removed any encryption on the phone before I started at 1.). My device is still unencrypted. I once removed stock encryption because I heard about problems with TWRP and encryption.

[Solved] Official Oxygen OS 5.0 boot loop problem for rooted users

Update: A working solution is listed below for reference.
A detailed tutorial for encrypted and rooted Nougat OOS users on how to flash Oreo OxygenOS without running into the infamous boot loop issue.
Step 1: Remove all fingerprint & pin from the device
Step 2: Backup everything on your PC/Laptop
Step 3: Reboot the device to TWRP bootloader
Step 4: Using a PC/Laptop, flash Blu_Spark TWRP via ADB command
Step 5: Reboot device to TWRP
Step 6: Wipe dalvik, cache, system & internal partition
Step 7: Format device
Step 8: Copy Oreo Rom & no_verity_mod file onto your device
Step 9: Flash Oreo under TWRP
Step 10: Flash TWRP again
Step 11: Reboot to recovery again
Step 12: Flash Magisk Beta for root (I used Magisk beta 14.5)
Step 13: Flash no_verity_mod file
Step 14: Reboot into Oreo Oxygen OS
Your device is now decrypted, rooted and running the latest stable Oreo OxygenOS build.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Seeing as a couple of forum members have messaged me regarding the official update of Android Oreo, I would like to make a proper discussion thread for it.
I just want to make it clear that HatRiGt has made an outstanding effort by making a tutorial thread. -> ([OFFICIAL] [Stable Oreo 8 ] Oxygen OS 5.0 Update [Tutorial-Root] [Mirror] by HatRiGt)
With that said, I believe the title is somewhat misleading. Since a lot of members are under the impression that this Oreo update will be a simple and straightforward process like all previous Nougat updates, except for it's not.
Stock OxygenOS
Rooted with Magisk v14
TWRP Recovery
Device already encrypted
Almost everyone with the device configuration listed above has run into some sort of serious issues, such as boot loop, file system decrypted/corrupted, or a complete data loss.
So far, it seems like the few groups of members that have managed to update their device without any data loss are either users that have flashed the Oreo Beta rom, or users with a non-rooted & stock recovery device. Almost everyone else is facing some form of issues.
I understand that some people have suggested that rooted users should first format the internal storage, before proceeding with the Oreo update. I personally feel that it is an inconvenient method of OS update, since many of us have a huge collection of photos, media files and app settings etc... to worry about.
The purpose of this thread is to address the aforementioned problem for rooted OOS users and to come up with a solution, so that everyone can enjoy this latest stable release of Android Oreo.
Any comments or thoughts are welcomed.

Maybe a stupid idea, but I am a bit noobish in this. Running stock 4.5.15, rooted, K2 TWRP and Magisk.
Is it not an option to just flash stock recovery (via ADB or Root Toolcase), then remove/deinstall Magisk and use the OTA update? After that flash Blue Spark via ADB, reflash Magisk and be good to go?
Unfortunately this is my daily driver company phone so I haven't the time to experiment with it at the moment.

I had some issues trying to dirty flash mine. Didn't know about others' troubles until after the fact.
I ended up with the black screen and blue notification LED. Everything encrypted and unable to go anywhere in recovery mode. Had to do a full wipe and image load; I also am not sure if I had been running my backups for a while, so this could be a lesson learned.

Still experiencing the exact same problem.
The problem is, I can't transfer the zip to my phone to flash.
Under TWRP, any computer recognizes it as a mass storage, but even with adb push/sideload it doesn't work.
Does a full wipe help with that problem?

I saw the same thing. Unable to copy the zip file until I did the full wipe, which means no chance of recovering what was on it, but I'm cutting my losses.
I'm now stuck on the configuration stage, it's just sitting on "Just a sec..." for forever it would seem. Trying to update on Christmas day was a bad decision.

Root *shouldn't* cause issues. But that really depends on what has been changed by root
Twrp will though.
Flashing stock recovery should allow the ota to work without issues.
Having said that it's a major update so factory reset isn't a bad idea anyway.

I had the same idea, encrypted, rooted (no system modifications) and running twrp, I flashed stock OP5 recovery, and updated through the ota and ended up in a bootloop.
I did a nandroid to a usb before updating, but I still lost all internal storage files

so...the no verity is only for decrypted users right?

I appreciated the suggestion, but there are a lot of users with loads of files stored on the device, along with various other app settings, having to wipe the storage or perform a factory reset can be really troublesome. I believe that OnePlus pushed through this stable OTA update with the intention of a seamless update. Endless boot loops and data loss wouldn't be an ideal method of an OS update.

The way I installed the beta 2, was removing the pin and fingerprint before installing magisk through Twrp, at first I got stuck with bootloop, but made it come back to life after installing the ota through Twrp and booting back, removing my pin and then installing magisk.

Okay, so I've been thinking that maybe it's possible for us rooted Nougat OOS users to update to Oreo stable release without any form of data loss.
I've listed the steps to avoid any potential confusions.
You start with stock Nougat OxygenOS (Encrypted) with Magisk v14 (root) and non-Oreo compatible TWRP (e.g TWRP 3.1.1.1)
Flash an Oreo compatible TWRP (e.g Blu_Spark TWRP)
Boot up the new Oreo compatible TWRP
Flash OreoBeta 2
The phone should boot up OreoBeta 2 without any data loss
Dirty flash the official Oreo stable release via the new Oreo compatible TWRP
Flash Oreo compatible TWRP again
Flash Magisk beta for root access
Flash No-verity file
So the basic order of flashing should be Nougat OOS -> OreoBeta -> Oreo Stable
Any thoughts on this?

Are you sure flashing Open beta2 won't compromise the internal storage? I bet no one affords to loose previous photos, apps, settings, etc without full backup.

I've triyed this. All good till i flash 5.0 & Magisk & no verity....

Hello there and Merry Christmas.
I faced to this issue too, fortunately before to update to Oreo. I made a full backup of my data.
My OP5 was running under Oxygen OS 4.5.15 Nougat 7.1.1
Rooted with Magisk V14.5
TWRP Blue_Spark 3.1.1
First I have updated my TWRP to Blue_Spark 3.2
And then I've installed Oreo Oxygen OS 5.0 from TWRP with the full zip.
After the update, my op5 has been bricked and locked on blank black screen with a blue led.
To unbrick my phone I used a tiers softwate to install Hydrogen OS first.
After that I could installed TWRP Blue_Spark 3.2 and then flash to the full zip Oreo Oxygen OS 5.0
My OP5 works as well but...
Right now I'm blocked, Google who usually sends an SMS, does not offer me. Only the authentificatorator or the security code. : /
Be careful, print a Google code to access your account when you go to install Oreo.
I'm waiting for Google to do the right thing.

Hi,
I have a boot loop on my OP5.
I ddirty flashed Oreo and had twrp/magisk.
Any ideas to recover my data partition ? (I had fingerprint/pin)
Best regards,

1) What is that "no-verity" file?
2) Isn't the regular TWRP 3.2.0 good with Oreo?

Isn't a full wipe required even for Oreo Beta builds? Also thanks for starting this thread I'm really eager to jump into Oreo but would love it if no wipe happened.

I think it's possible to flash the Oreo Beta without a full wipe. And yeah, I've got way too much stuff on my device, so I can't afford to wipe my storage.

I never suggested either.
Oneplus don't test using twrp or using root.
Their prescribed ota route, as pretty much every other OEM, is unmodified system partition using stock bootloader.
Twrp or root will affect those and can cause bootloops.
Obviously there's a chance with so much diversity in installs that there can be an issue arises.

Help getting from LineageOS 14.1 to OxagenOS 5.08 (Something wrong with flash mem?)

Hi,
maybe someone here can help me or point me in the right direction for a guide. That would be much appreciated!
I have a Oneplus 3T (A3003) that I flashed to LineageOS 14.1 with Magisk-Root a while ago.
I have been stuck on 14.1-20171005-NIGHTLY-oneplus3 for a while now, because since then, whenever I tried to do a nandroid backup from within TWRP, the backup failed because of some kind of error on the data partition (I believe). I haven't flashed a new version since then and haven't come around to it until now, because everything ran very smoothly. :silly:
Since I would like to switch to a more modern ROM (I was thinking of going back to Oxygen OS (5.08)) I started playing around with it yesterday and noticed that TWRP (I think 3.2.0) would not start anymore. It will always get stuck on the logo screen.
I then tried to flash a new version (3.2.3.1) through the Official TWRP app. It still got stuck on the logo screen and I tried flashing 3.2.3.0 after reading about problems with 3.2.3.1 but the results were the same.
Can you please tell me how to get TWRP working again and how to flash OxygenOS 5.08 on my 3T or point me to the neccessary guides?
Thank you.

As OOS implies enforced encryption of data partition, going to an from it can be a bit tricky. Simplest way is by wiping using Qualcomm factory restore tool and then just OTA upgrade or flash latest OOS zip.

@r_wraith, I'm thinking that your data may be formatted f2fs and be encrypted but no on-boot password, and have a lot of data in your user data. This could cause a long start time in TWRP.
So try waiingt for about 5 minutes when you boot into TWRP. It may end up getting past the logo screen.

That worked, thank you. Yes, my data partition is/was encrypted.

Since TWRP seems to be working again, do I need to flash some kindof firmware upgrade before I flash Oxygen OS or is this included in the OxygenOS-Image and only needed for flashing ANdroid 8 Custom ROMS?

The OOS zip includes the firmware. Custom ROMs don't because they use the OOS firmware. The firmware is stored in separate partitions so it isn't affected by wiping the system and data positions.
Since you're coming from Los 14.1 you'll need to do the following in TWRP:
- take a backup of your current system
- do a factory reset to clear the data partition without losing the files stored on internal storage
- flash the OOS zip file
- flash Magisk 18.0 which will root the phone as well as prevent TWRP from being replaced by the stock OOS recovery

OnePlus 3t with lineage os encryption doesn't work

Is it just me with this issue? Any known fixes or something? I'm using lineage os version 15.1 with latest update that released today.

i got it too. i always encrypt on lineage OS and omni, today i don't remember what last build i was on but i cleaned my phone and installed latest LOS, after that i can't encrypt my device anymore. even i tried older builds of LOS, NLOS and also OMNI. i can't encrypt my device anymore.
I formatted Data many times and formatted everything but still can't encrypt. anyone can solve this issue?
---------- Post added at 03:45 AM ---------- Previous post was at 03:10 AM ----------
just figured out the problem, problem was in TWRP 3.2.3-1. please install 3.2.3-0, and problem solved

I also have this issue on 15.1-20190127-NIGHTLY-oneplus3, has anybody got a fix yet?

Here's what I would do in your situation:
0. Take a backup of your current rom and internal storage and save it on your PC.
1. Try a different rom to see if it can encrypt your phone, eg Los 16 beta from https://androidfilehost.com/?w=files&flid=285406&sort_by=date&sort_dir=DESC
See: https://forum.xda-developers.com/on...ageos-16-0-oneplus-3-3t-t3866517/post78144505
If that works, you're done and can restore your backup. If not ...
2. Do a clean install of OOS 5.0.8 full zip from https://www.oneplus.com/support/softwareupgrade
Don't flash Magisk or custom kernel. Let the phone reboot normally. Check that the phone is encrypted.
OOS forces the storage to be encrypted. It will also replace TWRP, but you can flash it (use the version mentioned in the next step) after the phone has booted.
If this doesn't give you an encrypted phone then:
3. !!!This step will complete wipe your data partition (including user storage)!!!
Use this version of TWRP https://androidfilehost.com/?fid=11410963190603866112 and tap the Format Data button under the Wipe menu. Do not use the Advanced Wipe option.
This should give you a properly formatted data partition with the correct encryption space.
I would flash stock OOS 5.0.8 at this point and boot it to get a properly encrypted phone (I did this when I was testing this version of TWRP and it works).
You can then restore your data backed up in step 0. Also restore TWRP (the version mentioned above) and restore your backed up rom.
For discussion and info on this version of TWRP see https://forum.xda-developers.com/on...ial-twrp-touch-recovery-t3742894/post78661632
You could just do steps 0 and 3, but that's a fair bit of time and effort, which is why I suggested steps 1 and 2.

At this stage I trust OOS more than the custom ROMs to correctly encrypt my phone. Once it's encrypted I'm happy to use custom ROMs.
Also, this is my personal view, so others may have different views.
You could, if you wanted, just install a custom rom after formatting the data partition and see if that works.

[James] Moto E5 Play won't boot into Custom ROM(s)

Device variant: XT19121-2 James
Chipset: MSM8920
After repeated failed flashes I am on stock firmware using this guide. Phone boots and works normally right now, but I can't seem to flash any Custom ROMs on to my phone. I was using this post to flash Lineage OS 15.1, which worked successfully at first, but the WiFi wasn't working so I reflashed it. It still didn't work so I did it again, wiping Dalvik/Cache too. After the second flash attempt, my phone began to only flicker on and off. I made sure to always clean flash, factory resetting, wiping Cache and Dalvik, even formatting data, but no matter what I do it doesn't work. Also attempted other GSI images (arm, A-only) like AOSP, ResurrectionRemix and phhusson's Lineage OS 15.1 But they all failed too. I am using TWRP for James v 3.3.1 although I did also try other TWRP images like v 3.2.1 . But it makes no difference. Also used Magisk v19 like some guides suggested but whether I have Magisk or not, it doesn't work. Even made sure to push the fstab.qcom file to /vendor. Anytime a Custom ROM is flashed whether zip or GSI img it goes past the initial "bad key" or "N/A" screen and starts flickering on and off. Bootloader and TWRP works fine, but that's about it. Everytime a flash fails I go back to stock firmware (which always works) and try another ROM. I wonder why the first attempt worked but doesn't anymore even if I mirror the exact steps I took from stock. If anyone has any solutions I would be really grateful. Let me know if you need any more information.

have you taken any recent OTA updates?

Okay give this a try, I'm assuming you have old root access and TWRP installed.
Download any Android 9 GSI of your liking, boot to TWRP.
Do a complete nandroid backup of the stock firmware.
Do a factory reset then wipe system partition.
Next flash your GSI that you downloaded to your system partition.
After flashing is complete of the GSI reboot to recovery.
After reboot completed flash your open Gapps zip. Then reflash Magisk.
if you get a error message when flashing g apps then you will need to use magic g apps with magisk as it will install them systemless. I have to do this on my device because the partition doesn't have enough space.
Give that a try and let me know how it goes if you have any questions feel free to ask.

I also just noticed you are using the latest version of TWRP 3.3.1. I'm not sure if you originally rooted and installed TWRP with the original patched version by Cody or not, but if so make sure with the new version that you format your data partition to f2fs. As this will ensure correct mounting of the data partition.

Followed these steps exactly, including formatting the data partition to f2fs, and the same problem still persists. Screen just keeps turning on and off in a loop without booting into the ROM. I downloaded the Lineage OS 16.0 GSI A-only Arm version for reference.

have tried stock recovery, have tried no verity, have tried stock boot.img
nothing works. only able to produce powered on (black and blank) screen that turns on and off for a minute before returning to bootloader
PLEASE HELP
think i might need a 8.0 GSI but cant find one anywhere

I eventually got RR to boot on the james xt-1921-3 I installed XT1921-3_JAMES_T_MPCS_8.0.0_OCPS27.91-150-5-1-3_cid21 as a base, then used boot and vendor partitions from JAMES_T_OCP27.91-51-4_cid21_subsidy-TMO_RSU_regulatory-DEFAULT_CFC and it finally worked.

Followed these steps exactly, including formatting the data partition to f2fs, and the same problem still persists. Screen just keeps turning on and off in a loop without booting into the ROM. I downloaded the Lineage OS 16.0 GSI A-only Arm version for reference.

Message me, I'll host a TWRP backup for the XT-1921-3 that boots RR 6.1

Download the file from this post https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389 , then using fastboot, flash the vendor and boot img
fastboot flash vendor vendor.img
fastboot flash boot boot.img
then boot into recovery and flash the file from that post to disable dm-verity and force encrytion, after that flash magisk, then reboot to bootloader, at command prompt-
fastboot erase userdata
fastboot erase cache
fastboot reboot
that should get you booted - profit
