Hey,
I wanted to create an nandroid backup in TWRP and got error 255 in the process.
I got the log of the failed update:
cloud.directupload.net/dfZq
So i searched for a solution, and the internet said that i should remove the file wich causes backup to fail. The logs said it was '/system/app/AndroidPay'
This is a file, not a folder.
So i removed the file, keeping an backup of it, booted into TWRP and the backup still failed.
To my surprise the boot into OxygenOS fails now. It shows the Oneplus Powerd by Android logo, turns black and reboots into twrp. Recovery and Bootloader seems to work fine.
So I connected my device with my computer and tried to get the file back to '/system/app' using adb.
I tried 'adb push AndroidPay /system/app' and it seems to be transferred succesfully, however the boot into oxygenOS is still not working.
I think it can be fixed by formatting the device and flash OxygenOS new to it, but I really don't wanna do that.
General Information:
Oneplus 3
OxygenOS 3.3.4
Rooted
Xposed Installed
No custom kernal
TWRP 3.0.2-0
File wich may be broken: cloud.directupload.net/dfZs
Is there an easyer way than resetting my whole phone to get it to work ?
I'm sorry for language mistakes or maybe leaving relevant information.
Thank you for help
I've had same problem today, my solution is restore "System" part (only system) from old backup, it saved my data and OP3 works fine after that
Wipe system, then flash OOS and it should work fine. If it doesn't Im afraid you need to do a full clean install since it isn't system related then.
First of all, thanks so much to everyone for all the hard work creating and updating utilities for the Pixel C.
I have a rooted (but otherwise stock) Pixel C running the November update of Android 7/N (ryu-nrd91n) and am trying to:
1. Create an image of the userdata partition
2. Read/modify files
3. Re-flash the modified partition back to the Pixel C
So far I've been able to create a 24.8 GB image file using 'dd' but the file is unreadable, probably due to encryption.
I don't see any Developer Settings option to remove encryption or otherwise unencrypt the data partition.
What is the best approach?

Do you want to get rid of your encrypted data partition ?
- Format data (inside TWRP - and do not boot into system in between)
- Flash stock boot.img
- Install SuperSU.zip / or flash antother boot.img - with "encryptable" flag.
If you flash stock boot.img and boot into system your are encrypted again - automatically.
yes, "dd" will dump the complete partition including encryption ..
you may can "tar" the complete file system while decrypted .. similar to TWRP backup function.
Why do you want to "backup - modify - restore" at all ?
Why you don´t modify your files directly on data using root-explorer ?
Cheers

Thanks so much for the follow-up. The main goal is actually simply to be able to create images, and re-flash them reliably on a different Pixel C (replicating the exact system state). The modification step is simply to verify that it's working.
I was able to unencrypt /data using the method above -- Thanks, that's extremely helpful!
However, I'm still unable to mount/read the file produced by "dd if=/dev/block/mmcblk0p7"
Is there a better way you can recommend to make an image of the userdata partition?
How do you mount the unencrypted dd dump of data ?
mount -o loop dumped.data.img /mnt/data
As well you can untar all twrp backup files into one new data.img file.
Or tar the complete /data partition ... etc.
It's an ext4 partition ..
Of course, you can use the twrp backup files directly to restore on another pixel c device.
There is no modification needed at all.
Good luck!

That whole boot.img step.. is that why I always get stuck in a weird misplaced bootloop whenever I modify anything in TWRP? I just flash original boot.img in fastboot?

The boot.img step to decrypt data ?
It's a one time task.
Once decrypted you always need to root after new boot.img flash.
If you don't root or don't use encryptable flag boot.img you will get encrypted.
Not really related to bootloops.
What are you changing when you are using TWRP ?
If I use backup then restore it loops. If I flash twrp it just boots to recovery. Now that i think about it i never did root this thing properly. Well i did with a toolkit but that doesnt count. I went beta then hated it lost root on restore then when i tried to do it again i kept running into bootloops. It says in the forums here that its common ans to just fastboot reboot but that dont work. I cant wait for the new nexus 7

Depends what are you restoring
Do you backup / restore other partitions except the data partition ?
Pls don't
In general .. pls backup data partition only !
All other .img files should be taken freshly from image.
In systemless rooting world the su.img is placed on data.
You may have an older version inside your backup.
If you restore boot.img from backup, supersu ramdisk modifications will fail.
Flash what ever system.img, vendor.img and install twrp as recovery.
If you flash a boot.img, it should have stock ramdisk, to be able to let supersu.zip do the work for proper rooting.
At the same time the su.img on data will be refreshed too.
To summarize .. if you change something always install a fresh copy of your boot.img and run SuperSu.zip inside TWRP afterwards!
Hope this helps ..

In this case, we're only looking to backup and restore the data partition.
Once we have the raw image created by dd, what would you say is the most reliable way to convert it to something that can be flashed by fastboot?
I've tried several different utilities to convert it to a "sparse image" but flashing it just erases data and doesn't copy anything from the image.

Did you test img2simg as well ?
I use simg2img to convert the sparse to raw image, the other way around.
Or something like this below .. "s" defines sparse image.
make_ext4fs -s -l xxxxxxxx -a data data.img
Sorry, can't help you better now ..

Yes, unfortunately we've tried everything.
First we created the file data.dd using
Code:
dd if=/dev/block/mmcblk0p7
, which can be read as an ext4 image.
Then we tried using SparseConverter, ext2simg and img2simg to convert the raw image to a sparse image.
They all produce files of different lengths, and none of those files seem to flash successfully
They go through the flash process and report being successful, but the data isn't there.
Is there any way to debug this and figure out what's going wrong?

If you don´t get an error message from fastboot the sparse image seems to be valid.
How do you verify data partition after flashing ?
Are you able to mount and check ?
Also from recovery .. e.g. before you boot into system ?
For example on Nexus 7 flo there is still a userdata.img inside factory rom (6.0.1), but not for Pixel C anymore.
Maybe some permissions are required (file_contexts) - like on Nexus 7 flo too.
Sorry, no idea whats going wrong for you ..

You can backup all partitions you want .. but you should know the possible impact if you restore them.
And Yes - you can flash all partitions at the same time .. but normally you don´t flash data partition via fastboot - not on Pixel C.
In times of systemless rooting and monthly security releases there is no need for system.img backup anymore.
Unless you have special modifications inside your system.img.
If you were rooted before I recommend to use fresh boot.img and reinstall supersu.zip after change.
Just to prevent issues ...

Hello,
I've just installed the new OOS4.0, and I also wanted to update the filesystem to F2FS:
I've managed to get everything working with twrp-3.0.2-1.28 (ext4 cache/system - f2fs userdata) but then, I enrcypted the data via the settings menu, and now the TWRP fails to decrypt (password invalid). I understand that this is some kind of incompatibility since if I try with the official recovery it decrypts without problems.
Since I still have to copy all my userdata to the phone and install everything, what should I do before?
a) Keep data encrypted and wait for a TWPR fix, and eventually flash with the official recovery if needed?
b) Reformat and keep the data unencrypted?
c) You tell me?
Thank you for your help.
This is the only reason why I am still waiting for a proper twrp first. Don't want to decrypt my storage, and move all the data from my phone to laptop and then back to phone. Too much of a hassle.

I can't answer your question, but can I ask how you converted the data partition from ext4 to f2fs? I have TWRP 3.0.2-1.28 and OOS 4.0 already installed, and was wondering what the best way to do it is.
Do custom ROMS such as CM14.1 and XenonHD support f2fs?
Now, if I'm on OOS 4.0, no root, stock recovery; how can i get F2FS?? Thanks!

Well, I have tested this method both on OpenBeta9/10 and OSS4.0-
MOST IMPORTANT - FLASH TWRP .23, .28 HAVE BUGS WITH DECRYPTION AND F2FS (TESTED AND REPORTED BY MANY USERS)
1.) Flash 4.0 through stock recovery for dm verity error or flash 4.0 modem + firmware through twrp, skip this step if u r already on 4.0
2.)Copy all internal data to pc and make nandroid backup if needed.
3.)Wipe data to f2fs and cache/system to ext4.
4.)As wiping all these partitions, decryption will be gone and rom will be wiped, flash ur OSS 4.0(I prefer Builds like Experience Rom - https://forum.xda-developers.com/oneplus-3/development/rom-experience-rom-v1-0-t3522259 OR HyperStock - https://forum.xda-developers.com/oneplus-3/development/hyperstock-t3521946 , this one doesn't tiggers encryption and dm verity error.)
5.)Wipe cache and dalvik and reboot.
6.)Setup and install DiskInfo app to check partitions.
I know this method is bit lengthy, but u will get as u needed, decryption and f2fs for data with no dm verity errors.

Well, u can try flashing stock recovery and do factory resets for 1-2 times.
I have tested this on ob9 and got f2fs without wiping storage( As told by devs)
If this method doesn't works, then simply unlock bootloader, flash twrp and decrypt data with fastboot or through twrp cos someday u have to decrypt ur data.
Grab a holiday or sunday, copy all data and backups.
Enjoy F2FS life. :good:

Brother, as u have flashed experience rom which already contains 4.0 modem + firmware, then dm verity shouldnt pop up.
Try to download and flash 4.0 modem+ firmware again through twrp, if this didnt help then try Hyper Rom.
If nothing helps, then follow the procedure i mentioned, backup all apps through titanium backup and sync all google stuff, make nandroid if any thing goes wrong, download official 4.0 full zip, flash stock oxygen recovery and do a adb side load.
Then flash twrp and clean flash experience or hyper rom u needed and restore apps back with titanium backup.
Report if something goes wrong

I did try to do the last thing that you mentioned. I flashed the official 4.0 through sideload. And dm-verity issue did vanish. But I thought of changing everything to f2fs. So I changed the type of system, data and cache. And flashed the Experience rom. But then, a strange thing started to happen. I just couldn't save any screenshot or pics I click but I was able to install or delete apps. So, I again went to TWRP (was really a hassle because I had to delete everything on phone and change system and cache to ext4 leaving just the data on f2fs and then doing several reboots and factory resets to get everything working). And then I flashed Experience Rom and I'm back to square one with dm-verity...
Still, I'd try to flash 4.0 firmware + modem files explicitly. And then I'll report. Thanks for the info, brother. :good:
EDIT: I tried to flash the 4.0 firmware + modem files but no luck with dm-verity issue..
Btw, I've a question. What's the downside of having this issue besides having that splash screen of warning on every boot up?
Can anyone properly give instruction on how to install OOS 4.0 without getting dm error + F2FS?
there's a lot of instruction in other thread that making this confusing.

Here are the Proper Instructions to Install Oxygen OS 4.0 without DM - Verity Error and F2FS -
For Unlocked Bootloader + TWRP + Rooted users (Having any Rom installed before) -
Requisites -
Backup All your internal Storage Data - Sync all Google Stuff - backup all Messages or stuff.

Hyper Stock - https://forum.xda-developers.com/oneplus-3/development/hyperstock-t3521946
Procedure -
1.) As mentioned, BACKUP EVERYTHING.
2.) Flash stock oxygen recovery though fastboot or in twrp.
3.) Boot to stock recovery, sideload Official 4.0 ota via adb.
4.) Reboot and dont set up device ( not necessary ) enable developer settings and usb debugging.
5.) Flash TWRP .23 NOT .28 (.28 is bugged with decryption and f2fs errors)
6.) Boot to twrp, wipe /data to f2fs and /system and /cache to ext4.
7.) As wiping everything, copy any custom oxygen os build and supesu 2.79
8.) Flash any custom oxygen os build ( all these 3 builds flashes supersu itself, so no need to flash supersu, buy keep it for further later use.)
9.) Reboot, Setup and copy all ur stuff.
This method will surely get u a Rooted, decrypted, f2fs /data partition Oxygen Os 4.0.
For Stock/Twrp Recovery, Encrypted/Decrytped, Locked/Unlocked Bootloader, Unrooted Users (Those who dont want to root or decyrpt) -
1.) Backup is necessary as internal storage will be wiped, its a one time process as for now every Oneplus update will be f2fs /data compatible.
2.) ADB sideload 4.0 ota.
3.) Reboot and dont set up device ( not necessary )
4.) Go to backup and reset in settings, do a factory reset with internal storage ( This will wipe everything, BACKUP NEEDED )
5.) Let the process complete and check /data partition via DiskInfo app.
6.) If it isnt, do a factory reset again via stock recovery.
7.) If nothing helps, follow first method.
I cant guarantee this will work, but many users have reported this as working.
I think this will be sufficient.

Thank you for root users.
But if you flash Oxygen recovery & Oos 4.0 via adb you have just to wipe all in Oxygen recovery and your partition data make f2fs ?
After flash Twrp and custom Oos build.
I read in many post for flash Oos 4.0 you must have Twrp modify 28 ? With the 23 work too.
The problem they are no solution for root user to format data f2fs and flash custom Oos 4.0 directly with Twrp ?
Many root users flash custom Oos 4.0 with Twrp 27 but don't format to f2fs ! Stay in Ext4 and that run great. Ex : Fos.

On my phone what ever oos i install, 4.0, 4.0.1, 4.0.2, data it's formated to F2FS.
To remove DM-verity message it's easy.

For dm_verity, only the enable command is necessary, not the disable one.
It was like that in original post.
Hi there,
Last friday I broke my lcd screen, it simply does not turn on anymore. Tomorrow an UPS employe will pick up my device and ship it to OP for repair.
My device: Oneplus 3 running TWRP recovery and rooted LineageOS. Adb is enabled in dev settings.
So now I am trying to create a nandroid backup to easily restore my system and data when I get my phone back since OP will reset it ...
I had this genious idea to boot into recovery and create a backup using adb but I ran into a problem.
I have to unlock my device in order to create the backup :/
adb console:
> D:\Desktop\Fastboot+ADB\Win32>adb backup -f backupbeforerepair --twrp system data boot
> Now unlock your device and confirm the backup operation.
So now I am hoping any of you will come up with another genious idea or a workaround so I can create this damn backup
Thanks alot in advance!
If anyone else would ever find himself in the same situation as me I was able to create the backup by doing the following:
You can use open recovery script in TWRP. See http://wiki.rootzwiki.com/OpenRecoveryScript
If you have the file
/cache/recovery/openrecoveryscript
then TWRP will process it when it starts.
If the file contains
backup BSDO myBackup
then the boot (kernel), system, and data partitions will be backed up in compressed format and named myBackup.
So, on your PC, create the openrecoveryscript file, boot into recovery, use ADB to push the file to /cache/recovery/openrecoveryscript then reboot back into recovery. That should trigger the backup process.
Note, the backup will be written to the default location TWRP for backups.

When i try to restore stock image via Magisk Uninstall button i get error :
Stock backup doesn't exist.
I can't remember what i did so this happened.
But, now i have vanilla boot.img. Is there any easy way to maybe copy-paste the file and restore image using the same way i described here. Thanks

Stock boot backup lives in /data but I don't know how to put a file there Magisk manager will use.
You can manually write the .img to the current boot partition using dd while the phone is running (literally the same thing Magisk manager does) or you can use fastboot to write it. That's probably a little more easy/safe if you aren't familiar with dd.
The start of this guide uses the fastboot process.

I did it using fastboot, though i don't like the possibility of everything getting erased when used without holding vol-down button thing...
Thank you
