TWRP backup error 225 - Nexus 6P Q&A, Help & Troubleshooting

So I've tested this on 3.0.2-2 and 3.0.2-3
If on nougat you backup, then flash a custom rom such as cm13 or aokp, including vendor files, then wipe and restore original backup, you will be left with a borked sim due to vendor being corrupt.
Solution is to reflash appropriate vendor image rather than restore, then LTE will once again work. however that is not the end of the issue... if you try to make a backup after this series of events, you will be met with an error 225 which will not create a backup though restoring works fine.
Am I the only one?
Which twrp does not suffer from these problems? Because the only way to fix this is to flash a factory image and start over. kind of stinks because I'd like to test other ROMS and be able to return to nougat. I guess I might have to stick to boy gay and not play with the phone.
I'm unencrypted. Reflashing twrp does not work.

Had the same problem myself and this is what a search turned up.

FWIW I flashed twrp-3.0.2-3 and that did seem to fix it so I didnt have to go digging around in the logs.
I figure that was just luck tho.
You will have to search for the new twrp . Good experience that

Unfortunately this is an issue with making a backup rather than restoring and the issue is in the 3.0.2-3 as well.
I would tell you to try loading a 6.0.1 rom and corresponding vendor image, then try going back to 7.0, but you won't be able to create new backups afterwards and will need to flash a factory image like I am about to do in a minute here to fix it.

If you read what the error message is and check your logs when it fails to see what file it fails on for backup ( cant restore a backup that wasnt made ) as the link post says, remove the offending file and you should be good to go.
TL;DR ?
Backing up is failing on a specific file, check logs to see which one.
Sorry if we are on cross porpoise here. MY b/u works fine now

It will fail backing anything up. If I just select system, or boot, or data, all of them together, separately. Doesn't matter. Throws a 225 error.
I've read another post that offered the same information verbatim. You cannot simply remove offending files whimsically. It off the bat does this no matter what is what I am saying. The solution it seems for this particular issue has been to start over.

Followed adb log saying system/app/angler layout is not a directory. deleted the file, os regenerated, tried again, same issue.

Recently tried backing up in twrp running stock 7.1.1 with pixel mods, got the 255 error of execution fork. Seeing that backups are ESSENTIAL when rooting and modding, this is a huge issue. Any fixes yet?

Based on your errors (thanks for putting them all in there) it looks like you downloaded the update directly from Sprint (OTA), so you would think that the download itself was fine. But if it's saying it's not signed then the download must be corrupted. Try going back through the menu and saying firmware update again. If it says there isn't one available then you may need to delete update.pkg and reboot and try again.
Also just an FYI, Fresh ROM 4.0+ has the new update already in it.
ya.. ive was on modaco.. just didnt like it. is the fresh really that good?? i had problems with modaco when i goto edit a contact, it says social network not available, and doesnt let me edit it.

I meant it's been included since 4.0. Grab 0.6b if you like the blue theme (check the screen shots) or just 0.6 if you don't want the theme.
And you can't ask if I think it's that good... I make it.

Think it's something to do with BusyBox and how it installs, is it fixable without a total wipe?
Had the same issue with the OTA upgrade to 4.4 (had to do a total wipe and lost a lot of files on the virtual SDcard as a result).
Not sure if it is busybox causing your issue or not. What the error means is that something in your system is not as it should be. Did you remove or modify any system apps?
You can have root and a custom recovery, but you must be TOTALLY stock in order for the OTA to work.

So I am trying to upgrade to 4.4.3 and having the same issue however i cannot uninstall Xposed. The xposed uninstaller does not find process_app.orig to uninstall/resotre the original file. Where can I get this original file. Any suggestion on what to do next?

Have you installed xposed right? You have to open Xposed App and tap to "Install/Update" then "Uninstall". Remember to remove also all modules.
You should remove also ROOT files, just open SuperSU and uninstall it from SuperSU settings.

- Yes, I have installed xposed correctly and have been using it for months.
- Yes, I have deleted all modules from within xposed prior to attempting to uninstall.
- Yes, I have used xposed to do the uninstall - it fails, to restore the process_app.
- Uninstalling from any other app will not restore the original process_app file.
I need to push the file to my phone manually but I do not where I can get it from and unfortunately xposed did not make a copy of it for some odd reason. So here you have it. I guess if I cannot locate the file, my only option to fastboot a full version of the 4.4.3 losing everything on the phone. I know how to do that, I hope

I have the same problem. There is no app_process.orig file in the /system/bin directory. Does anyone have an original 4.4.2 app_process file for the Nexus 10?
This link shows how to use the full image without losing your data. I haven't tried it myself and would have preferred to just use the OTA image instead. But I may end up having to fall back on that approach.
Hi, been trying to update OTA with no success here. No idea if it's the same issue with app_process but here's what I've done
- Device status: Custom, so installed xposed framework, installed wanam, tick Fake system status and Device status changed to Official
- Choose System Update, and it's working fine up till this point
- Install the update and update will failed since wanam is still enabled (and it deletes the update file, so next time I want to OTA I have to redownload all 600 megs again )
- Now I tried to disable wanam and uninstall xposed (because I don't think I should uninstall xposed without disabling wanam first), however whenever I disabled wanam Device status will then reverted to Custom, preventing the install even if the update has been successfully downloaded (and yes, it deletes the update file again)
So any idea how to do it correctly then? Thanks

First off, next time you get the ota go into /cache and copy the zip file somewhere else so you don't have to download it again. You need to uninstall xposed from within the app

Yep, tried that as well. However even if I copied update.zip back to /cache/fota, software update still redownload the whole thing again
And yeah, I uninstalled xposed from the app
Question, in my previous post, after each steps (disable wanam, uninstall xposed) I always rebooted to apply the changes and device status reverted back to Custom after I disabled wanam and then reboot. Should I uninstall xposed without rebooting first?
I mean should it be like disable wanam (no reboot) then uninstall xposed (again no reboot) and straight to do software update?
Thanks for the reply though
Edit:
Okay, tried this.
Disable wanam (no reboot) so Device status still at Official. Then uninstall xposed (no reboot), app_process has also reverted to original. Last temporary disable root using Voodoo OTA Rootkeeper. But still software update failed
Any idea what other things causing software update refuse to updating?
I did however modify /system/csc/feature.xml, does it matter?

Uodated the OP with kernel source.
As far as the oringal thread there never was one. I just stumbled on Phreya's work. You could probably contact him here:
https://forums.kali.org/member.php?40476-Phreya
Update NetHunter as you refer to it is the framework required for things such as Chroot along with a few applications included within a normal NetHunter install. The reason it's so small is because you still need to download Kali (done in the NetHunter app)

Its a kernel along with penetration testing tools that runs on top of CM which is why I refer to it as a ROM. It functions slightly different than CM so I can't really call it a modified version of CM. You know Sailfish? Its kind of like that. The difference being Kali works alongside CM versus just using the libraries

Yup, same here! I always getting it while trying doing an restore via ADB (copy backupped TWRP folder via commands to internal device storage)
I would like a solution to for this frustrating Tarfork 255 error!
This is what i asked and mentioned to one of our Team Members and i tried everyting;
First: *I don't like the idea of "wipe data" clean restoring is to me included "format data*
Secondly: *if i backup my data also along with system and all (exclusive recovery, cache and system image) and move it to my pc via ADB and than wipe and format all in twrp and than move my TWRP back up via ADB back to my Device, than restoring fails...*
Thirdly: *So the only way you can restore is NOT to format Data(internal) while restoring. But that just doesn't make sense. Because the Data is dirty if you flash another ROM and than restore your previous ROM*
So in my opinion when you restoring without the Data formatted, it stays dirty when you restoring. Also i don't want dirty data from other ROMs if you know what i mean..
I like to know an very satisfying solution! And hopefully someone can enlightening us:crying:
It's very simple.. If you can find through the log the "guilty" app just uninstall it and re-do TWRP backup.. If you can't find that (or those) app you need to wipe data... When you're 100% sure that the problem is in data partition (try to backup it alone) so the solution is the above... :good:

I like to know an very satisfying solution! And hopefully someone can enlightening us:crying:

If you format Data you'll decrypt partion and when you go restoring a previous backup done with encryption it won't work.. You can even restore a full backup on a fully working system the recovery will wipe everything for you before continue (with everything i mean those partition that yuo've previously backuped)
Aaah i see. This is what i've got;
A backup (stored in my internal and PC) i made this backup on an running "encrypted" device. But in TWRP i had to decrypt it by password so the backup i made in TWRP is automaticly decrypted right? because of the pincode i insert to decrypt my data.
But let's see, if i want to; let say.. switch to another Custom Rom. The only way is to "wipe" all and flash the new Custom Rom? This without Formatting "Data"? (as i suppose) because if i format the "data" i'm not able to restore my backup. This does make completely sense to me. But..... one thing i don't understand is this;
Why is it possible to make an full backup in TWRP, push it via ADB to PC, going back to twrp "wipe" and "format" all, reboot TWRP, pull the backup from PC via ADB again to TWRP and restore. But it won't restore why? why? because i formatted the "data"? so the only way to restore is (with the "dirty" data from previous ROM's than)...
Anyway, i wish it all was easier... Maybe i make it myself to hard to understand, i dunno.... But hey, thanks for your feedback! appreciate

encrypted backup and a backup of a encrypted device is 2 different things.. When you do a TWRP backup you can choose to encrypt it with a password, it will encrypt that archive backup, but you can also do a TWRP backup of your encrypted device without encrypting the backup, hope this is clear
Second point.. Why you need to format every time? Format here on op5 can cause the data partition to switch from ext4 on f2fs and is not really necessary everytime... Example.. I'm on Resurrection Remix but today i want to change rom but first i want to take a backup, so i reboot in TWRP, do the backup (without encrypt the backup itself, it's not really necessary, indeed it can be risky) then i wipe cache-dalvik/art cache-system-data NO INTERNAL STORAGE then i install my new custom rom
It's really easier as you were thinking but maybe you've done some confusion with format/wipe and encrypted/decrypted
Your problem of restoring the backup is due to this ---> Probably, when you do the TWRP backup you're encrypted then you move it to the PC and here there's nothing wrong, but after this you format data and this will decrypt your device, so like i said above, your restoring isnt working because you want to restore an encrypted backup on a decrypted device
Avoid format and instead use the wipe function :good:
Now i see!!! Finally.. You're second post made it all clear to me! I keep this post in my subscriptions, so i can always look back.
Thanks again! (and for you're time to explain) :highfive:

Have you tried to backup Data only partition?
As I said above the 255 error is due to damaged file/s

If you are getting the same error again and qgain, i know its frustrating! And i also know to find the culprit for the error, is very hard. So i suggest start from scratch? I mean wipe all and format data, reboot to recovery, flash the latest "stable" and "improved" blu spark TWRP as recovery. Reboot recovery again, transfer the ROM, Gapps package and root method from PC to Internal and flash, reboot.
I know it's not an solution you'll be waiting for, but i ended up the same way too (as you can see earlier posts) . But since Hitman478 explained all to me, i have no issues anymore! which I'm truly great full for.
Have a nice Sunday (after all) :highfive:

There's a corrupted file.. if you can't find it out and delete/uninstall that app, you never will be able to backup.. your solution is to clean install again your room (but first look at log and watch where TWRP gives you the error)
I could resolve my nandroid /data backup error on my EMUI 8.0 Mediapad M5 device with those following steps:
1 - Use a correct TWRP implementation
TWRP need to access the uncyphered partition /data.
There no possibility to backup it, if TWRP does not implement deciphering user data partition.
2 - Remove all users except user 0 (the administrator)
You can verify that there is no unwanted users, looking at directory /data/user : the only subdirectory should be "0".
To remove the others users :
Remove the PrivateSpace if you have one (Settings > Security & Privacy > PrivateSpace, and tap on the garbage can).
Remove all the secondary users (Settings > Users & accounts > users, and tap on each users to delete them). Keep just the main administrator user.
On EMUI, remove all twins applications (Settings > Apps & Notifications > App Twin, and disable all twin apps).
On OxygenOS, remove all parallel apps (Settings > Apps > Parallel Apps, and disable all parallel apps).
On MIUI, remove all dual apps (Settings > Dual Apps, and disable all dual apps)
On others devices ... you must find all parameters that create those unwanted users.
If you are not able to get the correct settings to suppress those users, in last resort you can try this command : "pm remove-user user-no. (For example "pm remove-user 999").
3 - Do not forget to protect your backups by a password
This would be stupid to cipher your /data partition and keep backups of this partition unprotected.
These steps fixed the nandroid backup problem for /data partition on my Huawei Mediapad M5 device.
I post on this forum because I hope that this will be helpful for others devices owners.

Thanks! That was the clue I needed! I had installed the app Shelter lately which created a work profile (= second user). Uninstalling Shelter and deleting the work profile solved the problem.
Hi, I use App2SD and this error occurs with the date partition. It's probably the symlinks.

TWRP Backup fails with message "createTarFork() process ended with ERROR 9"

Hello,
I've got a problem I couldn't find a solution for: Before trying to flash a custom ROM, I wanted to do a Backup of the "original" system (rooted samsung android 4.4.2 KitKat). As listed by the devs of TWRP on their site (https://twrp.me/faq/whattobackup.html), I selected system, data and boot. System and boot were backuped to card without error (when selected without data), but backing up data always fails with error message "createTarFork() process ended with ERROR 9".
I could find threats about error 255, but nothing about error 9. Can you please help me solving this issue so I can create a backup of media as well?
These are the last lines of recovery.log:
