Just in case anyone is curious about F2FS, stock kernel and fstab support it and so does this TWRP.

I've formatted data to F2FS in Twrp 3.3.1-30 without needing to flash any additional zips etc. OOS has booted perfectly with no issues what so ever.

I just got bootloop after an OTA from oos 9.5.3 to 9.5.7 on GM 1910 and need some help

Here's what exactly what I've done.

1. (long before) install magisk follow https://xdaforums.com/oneplus-7-pro/how-to/guide-root-oneplus-7-pro-patched-boot-t3931205 and all work well.

2. (then today) upgrade magisk to 19.3 and reboot, work well

3. install "TWRP 3.3.1-32 Unified Unofficial Installer by mauronofrio" in magisk then reboot, success.

4. install OTA from system update

5. install "TWRP 3.3.1-32 Unified Unofficial Installer by mauronofrio" in magisk

5. install magisk -- direct

6. install magisk -- ota and reboot

7. got bootloop (not exactly the ones I got before though, the phone shutdown itself right after boot animation and reboot to recovery...)

8. first try -- install magisk in recovery then reboot, failed

9. second -- recovery - advanced - fix bootloop, got in the system but without magisk

10. reboot to recovery and then install magisk(magisk shows it detects patched image) and then got bootloop again

11. third try -- recovery - advanced - fix bootloop, flash uninstall-magisk.zip, boot into system successfully

12. reboot to recovery and flash magisk, boot into system successfully and all the module lost

so which step I've done is wrong since I don't what to reinstall modules on each ota update......

Hi guys!

I'm getting the createTarFork() 255 error backing up in twrp.

Tried pm remove-user 999 -> E:couldn't remove user 999

I haven't found the solution to the last error here yet. In case it's already been explained, I haven't found it and I'd greatly appreciate a link.

Thank you!
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Jack_Sparrow_:
I don't know what you did wrong, I just can say that using the "old" method (full rom flashed in twrp, flashing .zip twrp, reboot twrp, flash magisk and then kernel) worked without problems for me...
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] reaper000:
Yeah, what Jack just said to [MENTION=6075165]zzj0311[/MENTION]

I wouldn't mix up install methods of having system update install the ota, Magisk install twrp, and then twrp install magisk.

To fix your problem, I would probably clean wipe (maybe even extra clean by formatting the data partition and losing your photos, etc, so you'll need 957, twrp zip, and magisk on a USB drive) from twrp and install 957, install twrp zip, reboot to twrp, flash Magisk, and then reboot system.

Good luck!

try to backup again and if it fails look into the logfile.

maybe you have to delete data/system_ce/999 or something like this manually
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] stevekind:
Hey there,

some magisk modules tend to mess up your OTA process. Only way to recover is to uninstall magisk via uninstaller.zip (exactly what you did in step 11 :good: ).

Since there is no good consensus on which modules ruin your day, the only safe advice can be to disable them all prior to taking an OTA. You can re-enable them afterwards.

Another thing is, you have to do both of your steps 5 ( :angel: ) after the reboot in step 6, so TWRP (and magisk after loosing it again due to TWRP install) get installed to the new active slot.

Hope I could help! Cheers

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Tenchi4U:
I can happily report that I was able to update from 9.5.7 to 9.5.8 on my (Magisk) rooted OP7P (gm1917) today without issues using the most commonly suggested method (dl full zip, local install, do NOT reboot, reinstall TWRP using Magisk, reinstall Magisk to inactive slot, then reboot). Was a tense few seconds on that reboot,. luckily went to OOS loading screen and started up as expected on the updated version.

This is after I had a disastrous time getting into TWRP bootloops following all suggested methods last update (9.5.7). I eventually did a full factory wipe/reset during the last update to get things baselined again.

It's a bug with Magisk:

https://github.com/topjohnwu/Magisk/issues/906

---------- Post added at 09:07 PM ---------- Previous post was at 08:53 PM ----------

You have to enable Magisk Core, that disable modules that can cause bootloop, reboot phone, install Ota ( through system and then Magisk on inactive slot before reboot, reboot, then install TWRP zip in Magisk and Magisk direct install, and disable Magisk Core. Or you can install OTA with TWRP, but you have to disable all modules!!! ( Magisk Core works fine!) )
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] HottieLinus:
Something like this.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] mauronofrio:
Still not understanding, the bar on the top of screen is of 0,5 cm so nothing can create problems to you
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] HottieLinus:
The loading screen of your twrp is like the pic I attached, the background has 2 colors: black and grey, just an issue of aesthetics.

2. dirty Flash 9.5.8 full zip

3. flash recovery TWRP 30 installer

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Nicotin3:
So I need some help here.

I had the problem above and after that I followed the steps below:

-Flashed the OTA update again, together with TWRP and magisk no change.

-uninstalled all the Magisk modules and then again flashed OTA, TWRP, and magisk - no change

-decided to restore backup from 9.5.7

-ended with bootloop

-managed to enter TWRP and decrypt after that, restored again the backup (data,boot,vendor,system)

-ended again with bootloop.

Now whatever I do, it's in bootloop and when I enter TWRP I cannot mount data. It enters directly to TWRP without asking for security pattern.

Kindly help! :(

EDIT: I was guessing everything is back on 9.5.7 so I flashed via fastboot 9.5.7 stock boot img, now I am missing also TWRP.

EDIT2: Finally working. I had to flash TWRP 3.3.1-32 img again and installed it, then it was possible to decrypt and mount the data. Flashed 5.9.8 img again, TWRP and reboot. Looks like everything is back to normal now, even the settings menu.

https://xdaforums.com/oneplus-7-pro...nofficial-twrp-recovery-t3931322/post79752238

I'm currently on 9.5.7 (on slot B) on my OP7p GM1911 and trying to update to 9.5.8. I did steps 1 to 3 in your method and at step 4 when I reboot to recovery on inactive slot A, I don't see any option to decrypt using unlock pattern in twrp recovery and hence I can't flash magisk.

I then booted into 9.5.7 on slot B and flashed magisk thru magisk manager by selecting option to flash magisk to inactive slot A but still I cannot boot into system in slot A and it takes me to recovery again which has a missing option to decrypt data. whenever I reboot into recovery in slot B I see an option in TWRP to decrypt data but not on slot A. Am I doing something wrong? Please help....

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] coolvabs:
I tried disabling all security (pattern, fingerprint, face) and again tried from step one. But I am getting stuck at step 4, whenever I boot into TWRP recovery after flashing ROM and TWRP installer, I cannot see any files on my sdcard to flash and hence cannot flash magsik (perhaps it is not able to decrypt storage) even without a pattern. Without flashing magisk it enters into a boot and recovery loop as mentioned before.

I tried flashing stock boot image for GM1911 9.5.8 but still get a boot and recovery loop, it reboots into stock recovery rather than going into system.

Have already wasted 4 hours trying different methods, am really frustrated now - have always used root/magisk on all my previous OP devices (OP1, 3, 5t, 6t) but never faced any major issues - OP7P is driving me nuts....:mad:

Why are you flashing OP6 kernel?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] kahila:
Hello everyone!

I have a question regarding flashing new OTA, remaining rooted and the slots a/b.

First, I was rooted, using TWRP and xXx module. Used a point-by-point guide from here to update OTA with Oxygen Updater and recovery. All went fine, at least I thought so. Noticed today I was not rooted, tried to manually flash root from Magisk. App did not give me that alternative (just download and select path), so I just went to recovery to flash it. Went bootloop, thought it was the magisk modules, deleted them, no change.

Then 1. factory reset 2. flash OTA 3. flash TWRP 4. reboot 5. tried to flash magisk, no go. 6. switched to different slot 7. booted normally.

Now I really don't have any clue what to do. Did I make mistake when I switched to different slot? Now when I try to flash magisk, at least it is not possible through the app. Now the phone is functioning normally and I don't want to make things more worse. So what to do? Start from the beginning (factory etc.) or is everything as they should be? And what about those two different slots?

Really appreciated for any advice, thanks!

We don't know bc we can't fix "my wifi don't work after flashing." We don't know what u did and how u did it, we need more info. What model phone, what OS version, what version of twrp, how did u try to install... Fastboot or magisk, did u root it afterwards? Tell us step by step what u did, most times wifi not working is bc u flashed the wrong boot.img, start off by flashing stock boot.img of the model and OS version and see if that fixes your wifi or flash the patched boot.img and install TWRP as a magisk module then direct install magisk then reboot.
