Development [r20] arter97 kernel for OnePlus 9 series

[bugac]

Have you faced any random reboots with r2?

yep, sometimes twice per day. returned to r1, and lets wait from arter update and fixes in r3

 

[samwhiteUK]

yep, although it took a while to get one (others were getting random reboots sooner than I was) -- in short, when I open my camera, I have about a 1 in 4 chance of getting a reboot, don't know why, but that is the only time I get them. went back to stock bc having my phone reboot when trying to take a video on xmas is something I don't feel like dealing with unfortunately. thing is this kernel is awesome in every way and I wish I could continue using, but that's the deal breaker for me

It was the camera for me too. Hopefully it gets fixed!

Just want to double check. If I would like to update to 11.2.10.10, the safest way woud be to do a local upgrade via a full installation file, re-root via magisk and flash back arter via FKM?

It won't work. You have to restore backup of partitions altered by this kernel.
You can also try other methods mentioned in comments above.

Ah ok, because if I read from the first post, installing a stock ROM with a full OTA restores the said partition. So that method doesn't work anymore huh.

/* Notice */

Only OxygenOS on Android 11 is supported.

This kernel touches vendor_boot and dtbo partitions, meaning you'd need to restore said partitions whenever you're switching to another kernel or stock.
Please make a back-up of these partitions. The installer doesn’t do this automatically for you. Installing the stock ROM with a full OTA restores said partitions as well.

Thought so too, but it turned out differently

this is for anyone that was asking about the easiest way to do this process:

(if you don't have dtbo/vendor_boot/boot img's backed up): go to the telegram group for this kernel, find the user 'ileux' who posted 11.2.9.9AA img's, download all three (he posted an already magisk patched boot img), reboot to fastboot, run:
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash vendor_boot vendor_boot.img
reboot to oos
then local upgrade 11.2.10.10 (don't reboot when done)
flash twrp.zip from nebrassy's thread in magisk (if you use twrp) - don't reboot
flash magisk to inactive slot
- now reboot
profit

I don't think that's the easiest way since you install twrp anyway.
You can install twrp, install the full OTA via twrp, than reflash Magisk and kernel via twrp. All works fine fore me.

yeah I get that, but I don't use twrp to flash oos unless I absolutely have to, but that works too. with this method you take care of everything without having to reboot until it's done

Reading other peoples experience with updating, now I know its not only me that got screwed.

Usually local update overwrites my kernel and root and i just flash magisk on the other side and reboot.

Ill stick with stock kernel for now

What happened to yours?

 

[infamousvincci]

What happened to yours?

Usually i download the whole update (3gb) from oxygen updater and local update using the system and then flash magisk on the other slot (for ota) and then reboots.

But with this kernel, i cant do that. Something prevented me and it keeps failing so i tried to restore my back ups dtbo, vendor, boot and it soft bricked my op9. Black screen at all. Thankfully msm tool saved me and now im just gonna run 10.10 rooted with stock kernel.

Oh man sorry to hear that, I gotta do a proper backup then before attempting to restore back up and update hmm.

This kernel is pretty good but it kinda is a deal breakef for me since im always on the go and i rely on my phone a lot.

I must be the only one that works like a fable

So I tried local upgrade straight and it failed like how everyone else mentioned.

Managed to use the backup boot/dtbo/vendor boot images from the previous Omega kernel I was using. Flashed that, booted up and local upgrade works again, followed these steps and am back to rooted stock rom again.

Will observe using stock kernel for a bit and see whether they fixed any issues from previous stock or not.

I know this may not be supported officially in regards to the few posts above, but I personally flashed the last OTA in TWRP. Not sure if I had to but then I flashed TWRP retention script(magisk), kernel, and magisk. Everything seems okay so far and was a lot easier then the usual process.

 

[l_mike]

I am wondering if it is possible to restore partitions with twrp?

for dtbo and vendor_boot, you need to be in fastboot (or you run the risk of an unintended outcome), however, you can flash your boot img and restore that in twrp, simply bc that's technically the kernel.

 

[Partigiano0105]

Could you explain to me how to restore vendor_boot and dtbo ?. I want to update the system and I cannot do it. I get an error message on installation
