I am also one with latest firmware, nitrogen, twrp, starting with full format / wipe... had /data/per_boot file and no backup would complete with out errors. Tried no data, data partitions on backup same errors and no digests to validate. Removed per_boot directory did backup completely..yeppy..

Edit 1: FYI just a caution after I removed /per_boot, did twrp backup, rebooted and battery demand dropped like a rock.

Edit 2: backup restore worked fine though.

I have been searching for more than an hour for a solution of this issue [ createTarFork() error 255 ], I tried several suggestion like deleting data of multiple users etc but none of them worked, until I read my TWRP recovery log

((( Error adding file '/data/per_boot' to" )))

So, the terminal command you inserted solved that issue for me, thanks alot brother <3 :good:

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] duckredbeard:
I may be a bit behind in the times, been quite happy with 5.1.7. But now I want the latest ROM and TWRP. Coming from OOS 5.1.7 and blu_spark 3.2.3-x (v9.85) and I want to update. I had a post many months ago that got an answer, but never acted on it. Has anything changed where I need to do any thing in any specific order before making the big jump. I am on stock rooted ROM, never really knew if i was encrypted or decrypted. All I did was root the OOS ROM with Magisk.

As I understand it, I need to flash twrp-3.3.1-1-20190713-codeworkx-dumpling.img from the recovery I have now, then I can flash the OOS that I downloaded from 1+. Of course I will remove all passwords, pins, fingerprints, face unlock. And do a backup of the current ROM while still in the old recovery.

Should I do another backup after flashing the 3.3.1-1 and before flashing the new OOS 9.0.11?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] duckredbeard:
I just completed a remote session with OnePlus, where they updated my device to 9.0.11. Since my last post, I screwed up my device and lost recovery. Now I am back to stock, right out of the box, newly updated and setup 9.0.11. USB debugging is enabled, OEM unlock is enabled and I was told bootloader is still unlocked. The device shows up in adb devices while connected.

Now I just need to "fastboot flash recovery twrp-3.3.1-1-20190713-codeworkx-dumpling.img" while in adb? With said recovery file located in the adb folder, I expect.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] shadowstep:
Yep, that'll do.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] duckredbeard:
Just a heads up, after the OnePlus support remote session, the bootloader was relocked. I was able to fastboot oem unlock and proceed as normal. I made a rookie mistake and forgot to flash Magisk while in the first boot of the TWRP. (Failure to flash Magisk causes OEM recovery to persist.)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] coder786:
I faced the same issue awhile back. I am on stock ROM with TWRP v3.3.1.

I found a possible solution on another oneplus device forum, might have been the OP5.

According to it, it was a problem of using OOS's parallel apps feature.

So I disabled the parallel apps that were enabled in Settings>Utilities and ran the follwing adb command to completely remove all the data causing this error:

su pm remove-user 999

From what I understood, '999' here is the id of the pseudo-user that OOS creates in order to facilitate parallel-apps.

This fixed the problem for me, hopefully it works for you guys too :)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] shadowstep:
You can make TWRP persist even without flashing Magisk by flashing the OxygenOS TWRP Retainer zip from this post of mine.

Does codeworkx pie recovery work for 10.0 (Q) Beta?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Dior DNA:

Wipe everything

Flashed A10 zip

Flash twrp.img

Reboot recovery

Reboot system

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Anoses:
You need to flash magisk before you reboot

Like this flash Rom flash magisk and then reboot
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] jc1266:
What about if I don't want to keep root , just wanna use twrp only how ya ??
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] WireMessiah:
Correct me if I'm wrong but you can't keep twrp without flashing magisk as magisk script retains twrp through some procedure it does. The only way without root would be to let the ROM boot first then restart to fastboot mode and flash recovery through ADB fastboot.

This is due to the recovery being linked to the boot image and that gets replaced when you install an update. That's why magisk works as it patches the boot image. If you had experience in coding you could probably find what magisk is doing while patching the boot image in relation to the recovery and build your own script and addon.d support which would in theory always keep your recovery after every update.

I don't think if you copied your boot image before the update and re flashed that it would work. as I'm sure the update would have probably changed the boot image to some degree as that's how your recovery gets replaced with stock.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] osm0sis:
You either need to root to prevent the ROM's recovery-from-boot script from running, or, allow TWRP to write to /system so that it can disable that same script.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] shadowstep:
You can. :) If someone wants to stay away from Magisk but wants to retain TWRP (with an unlocked bootloader, of course), then he/she can flash the OxygenOS TWRP Retainer zip from this post of mine. :)

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] scrouthtv:
Bootloop with Android Q and Magisk 20.4

I installed Android 10 some days ago from OP. Today I decided to root my phone again.

I installed twrp-3.3.1-20190908-0-codeworkx-signed-forcedecrypt-dumpling.img and booted into it. I double-checked that it would not be overridden by the OEM recovery and then flashed Magisk 20.4 from GitHub's releases page and cleared Cache & Dalvik. I then tried booting into system but it's just showing the Boot Animation for 20 minutes now.

If I uninstall Magisk everything works again.

Another thing to note:

If I open a Terminal in TWRP (with & without Magisk installed) I get an error upon every new line:

dumpling:/ # any command

Linker: WARNING: couldn't read "/system/etc/ld.config.txt" for /sbin/toybox" (using default configuration instead): error reading file "/system/etc/ld.config.txt": Too many symbolic link encountered

WARNING: Linker: Warning: couldn't read "/system/etc/ld.config.txt" for /sbin/toybox" (using default configuration instead): error reading file "/system/etc/ld.config.txt": Too many symbolic link encountered

I guess this results from some old Magisk modules I had installed before upgrading to Android 10 although I'm not sure.

Someone (reddit[.]com/r/essential/comments/97r01q/bootloop_after_installing_magisk/e4b119u) suggested

to reflash the stock (or stock'ish) boot.img file

but I don't have any boot.img

How can I provide further logs to solve this issue or where can I get additional help?

Thanks in advance

Too bad they are just a fork of TWRP and don't contribute their patches back upstream.. :rolleyes:

TWRP however continues to move forward; despite you not liking the UI as much, it's still the most up-to-date overall.

I'll leave this here, they're fixing other devices still before they do the official release, but dumpling seems solid: https://build.twrp.me/twrp-3.4.0-0-dumpling.img

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] KLit75:
I have a couple of questions. It's been nearly a year since I've flashed anything new.

Is it the TWRP from July or September of 2019? (I noticed the slightly newer one has force encryption which probably means I need no verity) If that is the case, which no verity zip are you flashing?

And it mentions "gapps if vanilla" in the instructions... This comes with gapps preinstalled, right?

I'm using a Pie version of Derpfest from last September. My TWRP is Blu spark, can I flash the Codeworks version from within Blu Spark TWRP? AND once I do that, it does nothing to the system partition, right?

It only touches recovery which means the currently installed rom will be intact and able to boot...

Sorry about all the questions. I just want to make sure it goes smooth. I read through the thread but still not 100% sure. Thanks.

[MENTION=3208754]codeworkx[/MENTION], why is it that TWRP can read OOS Oreo B1 PINs on a clean flash from the stock recovery, but can't if the ROM is backed-up in TWRP, another Oreo ROM (eg, Omni, LOS) is flashed, then OOS Oreo B1 is restored?

And it doesn't matter if OOS is backed-up with or without the PIN, or of a PIN was used with the new Oreo ROM.

And default_password doesn't work either... :confused:
