Hi all,

Assistance needed.

Just updated to r65 and all is good.

Tried to convert to f2fs but I get this error....

FKM: Auto-flash ended in failure

This only happens when I flash the f2fs zip from his site. All previous versions and current flash perfectly in FKM with no issues, only f2fs-liveformater does not work. I'm I doing something wrong?

I'm on OOS 10.0.14 HD01AA
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] muloot:
Updated my OP7 Pro to OOS 11 today, tried flashing the r65 and now am stuck in bootloop.

Error message: boot reason: fs_mgr_mount_all.

Unable to parse kernel log.
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] zoleegee:
This kernel won't work with OOS11...

You need to flash the whole rom again somehow from bootloader/adb... I'm not sure exactly how though... or maybe only the OOS11 kernel via adb shell.
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] muloot:
Okay good to know :D my bad then. Any idea where i can find the original Kernel?
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] zoleegee:
Head over to https://xdaforums.com/t/oxygenos-an...o-released-open-beta-4-now-available.4221067/ - the OP contains a link to the OB4 extracted images.

Not sure which one is the kernel though from the zip... :P Probably the boot.img - by the look of the size of it...
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] muloot:
Didn't work that way, or i didn't get it to work. Went back to OOS10. Is this kernel going to available any time soon on OOS11?
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] -Deco-:
Flashing the current iteration of the kernel is not possible with OOS 11, it was built for Android 10 and OnePlus have not released the kernel drivers yet for OOS 11.
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] muloot:
@-Deco- Went back to OOS 10 - thank you for the response buddy!
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] DJ_BARO:
This is a great kernel, big thumps up!

I just was interested in converting data to f2fs and see the performance difference. But problems are unfortunately occuring.

How do i clean install with twrp an current OOS 10 Stock Rom (10.0.11) with your kernel and data partition in f2fs?

it looks like i'm doing something wrong as mentioned because i got wiered behaviour like at the start not recrognizing my paid apps in PlayStore, Force Closing Apps (especially on first load up), Renovate Rice Tweak App not working, viper4android staying at abnormal...even with audio fixes.. and music if started playing with an connected headset first starts playing on loudspeaker..

anyone else with some kind of theese problems? Any expierence with f2fs and current stock rom?

is there a speed difference against ext4 in real life scenario? (Like opening and switching from apps and system in general?)

Many thanks already for any held provided by you all! :)
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] LamarrCZ:
Running OP 7 Pro with latest OOS 10, with r65 kernel and data formatted to F2FS using TWRP + arter's optimization script.

Everything works flawlessly, no issues at all.
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] DJ_BARO:
Sounds great, thanks for letting us know. 👍

Do you mind to tell me/us in all steps with Clean Stock install how you did manage to do so. Because i tried already a lot of options but theese will all fail at the end. 🤔

Many thanks!
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] LamarrCZ:
Ok, let me try.

I've just used all the instructions provided by arter already, nothing fancy.

Make sure you use latest TWRP version (https://eu.dl.twrp.me/guacamole/).

1) Ideally, factory reset your phone - in OS or in recovery, doesn't matter, but I prefer the recovery way.

2) Flash latest arter's kernel.

3) Flash magisk 21.4 - I know there is newest version 22.0, but I have problems with updating.. I was stuck in fastboot after flashing it, so I've recovered my phone and stick to good old 21.4.

4) Now it depends on your phone.. I've got 7 Pro (not T version), which has simplified way to convert to F2FS. With 7/7 Pro, you just have to format your /data in TWRP recovery. So, go to Wipe > Advanced Wipe > tick data > Repair or Change filesystem > Change filesystem > F2FS.

4*) If you have 7T / 7T Pro, the process is more complicated, look at main post in this thread.

5) After that, flash optimization script by arter - https://arter97.com/browse/f2fs/optimize/20190607/ .

6) That's all, you are good to go.

Honestly, don't know if there any "noticable" differences in performance, because I've just recently switched from 5T, so rooting + custom kernel was the first thing that I've done after getting phone in my hands.

But I have to admit, phone is flying and battery is also great for me (considering I'm using full QHD+ and 90 Hz combo).

One last tip, stay on Android 10 for now. I know Oneplus released "stable" OOS 11 update, but what I've heard from lot of ppl (reddit and OP forums), update sucks, there are some problems with overheating, bugs and features missing . I'm now waiting for it to get more stable, also OP has to release new kernel sources so devs can update their custom kernels to A11.
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] DJ_BARO:
Thank you very much for your deep explanations and that step for step guide, i do highly appreciate that.

I did manage to run the system with data formated to f2fs. First of all i was happy but then my phone started to have problems with the mic on phone calls and exiting the call itself. I wasnt sure what could cause that issue but at the end i decided to stick with ext4 again for stability reasons.

Someone had similar issues or do have an explanation why it could have been for me?

Still many thanks! Yeah definitly goona wait for OOS 11 coming stable. Just a shame really it isn't even in March 2021...But anyway

EDIT: I do have an OnePlus 7 Pro

UPDATE: Will have another try by a clean install, will tell you if i figured it out! :)
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] uhero2:
Today Oxygen updater says android 11 stable is available for my OP7. I'm really undecided, android 11 has AOD, but android 10 has arter kernel. I don't really wanna lose the smoothness... I guess I'll stay on android 10 for a while
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] GreenApp:
Thanks for the update arter97! However my visual voicemail disappeared!

Edit: Disabled all magisk modules, reinstalled kernel, and got it back on, reinstalled magisk modules, it's still there. All good!
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] Ramalama:
Hi, anyone tryed this kernel on crdroid 7.4 or Derpfest? (Both are android 11, but based on aosp). Both uses the crdoid kernel:

GitHub - crdroidandroid/android_kernel_oneplus_sm8150

Contribute to crdroidandroid/android_kernel_oneplus_sm8150 development by creating an account on GitHub.

github.com

Somehow the bootloader etc should be based on android 10, because twrp still works...

Thats why i ask xD

Cheers
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] Adromir:
How do you think a bootloader (which is part of the manufacturers official firmware) gets an update through an unofficial Software build?
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] Loercase:
A11 runs pretty much perfectly for me on my OP7Pro now, after a few hiccups at first.
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] Ramalama:
i wrote that the bootloader is from android 10 and the crdroid kernel+os is android 11.

because as far i understand, the kernel here isn't compatible with oos11.

But the crdroid 11 kernel, shouldn't be much different from this here.

That's why i ask.

https://xdaforums.com/t/kernel-android-10-11-nem0-kernel-for-op7-series.4226729/

Here is an another example that works with oos10 and aosp10/11.

So why the hell you conter my question with your unrelated nonsense question?

All what i want to know is, if it works with aosp11.
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] Adromir:
If you look closely at the linked kernel decription, it says it is a unified kernel for Android 10/11. So it means it is a kernel which has modifications for both Android 10 and 11 which gets (de)activated for the Android- Base you are running on your phone

The OP of this kernel clearly says:

So as long as Arter isnt stating something else, you can safely assume that this kernel is not compatible with Android 11. And why i was asking that Question? To make you rethink your assumptions, because you are basing them on a wrong understanding on how parts on your phone are tied with each other (or not). A kernel or a rom can be tied to a certain firmware but it doesnt have to. So what does it means for your question? While crdroid and their kernel and any other rom can run on a Firmware released for Android 10, it doesnt mean everything can run together with a Android 11 Rom base. OOS Android 11 will most likely (but not necessarily) come with a firmware update, which will be required to install it
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] Lossyx:
What does the bootloader have anything to do with this?

This kernel does not support custom ROMs, if if did, then it would work with AOSP 11 roms (not for long though).

This kernel is strictly OOS10 only.
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] axelander11:
Hello there :)

This kernel is amazing and works great. Im currently running r65 on my oneplus 7t on newest android 10, without a issue. I have a question in terms of cpu tweaking and I hope someone can help me out with this one.

I love the fact that I can tweak my cpu performance with my rooted phone (for ex. with kernel auditor), cause it makes my phone, even with this efficient kernel, run like 30% longer in powersave profile. Unfortunaterly I can't enable the alternative cpu profile "powersafe" since a couple versions earlier of arter kernel(Symptom when profile "powersafe" is selected and the button "CPU-Govenor-Settings" is pressed: Message something like: "powersafe cant be selected~" in english). If someone who has an idea what to do or how to add powersave values/profile to arter kernel can help me out, I would be more than grateful.

r70a1 is up and it "could" be a major release.

r70 brings a major change in certain subsystem in the kernel that affects battery life, performance and memory management.

Because I want feedback from blind tests, I'll keep the changelog to myself at this point.

Because of something I've changed, you must use your phone for some extended period of time for it to fully kick in.

DO NOT provide feedback in less than 36 hours after installing the kernel.

Also, this version of the kernel now directly affects the system-related partition on your device.

Nothing can catastrophically damage your phone, but as always, back up your data.

I've been testing this build for several days now, and it seems stable enough.

While I don't expect any random reboots, I'm still marking this as an alpha build.

[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] Nimueh:
Hmmm, doesn't look like it 🤷‍♀️

I installed 2 different apps from the Playstore to test sensors and the proximity test didn't work with either of them. No idea how to test it in real life use though.

I honestly want to raise the question to you, if you should really temper around with your device if you don't know how to solve this and how the root method work. I don't want to mock you, but at this point, you might brick your phone
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] pcp12:
Sorry but I've been using root for years, testing roms and kernels. I'm just worried about the f2fs patch on the Oneplus 7T because it won't start if the arter kernel is not installed and I don't know if flashing a boot patched with magisk I can lose the arter kernel

Edit: Also when flashing the arter kernel in FKM it showed the message "Patching boot with Magisk" or something like that, so I thought it was not necessary.
[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] cocacola2015:
The kernel is a linux kernel, Android uses that for their OS but it'

s the same kernel that you run on normal Linux.

In the kernel you need drivers for special hardware, it's like a graphics card, when you plug in a new graphics card, you need a driver for it, but it doesn't replace the windows kernel.

One of the things that the linux kernel does is run an "init" process, this is the first process with process ID 0, and then the rest of Android boots afterward.

So there is no problem running the same kernel as long as it has the drivers for ALL hardware. OOS11 doesn't care, one of the purpose of the kernel is to serve "syscalls"

System call - Wikipedia

en.wikipedia.org

This remains the same across all linux distributions so both OOS10 and OOS11 will use the same system calls.

[OnePlus 7, 7 Pro, 7T, 7T Pro Cross Device Kernel D] Adromir:
Then I'll give you a short explanation, how to get there;

Boot device into twrp (not install it, just boot via fastboot to have an adb enabled recovery)

Pull a dump of your installed boot image onto your sd card

Reboot go to magisk Manager and patch this boot image

Flash patched bootimage via fastboot

You should be on root again and arter kernel still installed on your phone
