Development [r20] arter97 kernel for OnePlus 9 series

[MrSteelX]

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

You could just temp boot twrp and have it flash update.

People say on Telegram that random soft reboots may be caused by old Magisk version. I am not sure, but after I updated to newest canary I haven't experienced any random reboots.

I would say that's incorrect that they assume that (it doesn't make much sense technically speaking), arter believes it was a tag merge that was the culprit of soft reboots on r2, simply bc r1 didn't have that issue (he is using stable Linux as base (not oneplus source). however, magisk v23 is not technically old as there is no new stable magisk yet, only canary (w/out magiskhide) but that's a whole different debate lol. arter uploaded an r3 test to his website to see if removing that merge (might be more than one merge but he didn't specify which one(s)) will solve the r2 soft reboot issue for those willing to test btw

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 followed this to upgrade.

At first, I flashed the backup I originally made of my stock kernel via Franco manager. From before flashing Arters kernel.
That was a mistake and didn't work... Ended up stuck at boot animation. No idea why I thought that coud have worked...

Downloaded the files from Telegram, flashed them in fastboot, did the local upgrade but when I wanted to "Install to Inactive slot" via Magisk, that option was no longer there...
Rebooted to fastboot, flashed the magisk patched boot from the telegram post of ileux, rebooted and everything worked.
Flashed R1 again.

Probably not how I should have done it, but here we are

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

Exactly this, though for me it's probably once every 10 times I open my camera. So far it hasn't been critical but is still annoying having to wait for the phone to boot back up. Coupled with the fact that the OTA update fails for no apparent reason (as already reported) leaves me a bit miffed. Not sure if I should hold out for an r3 whenever it gets released, or return to stock now.

Hi,

I am using this kernel for a while. Now, I want to install OOS 12 with a fresh installation. I also want to unroot und re-lock bootloader. What are the steps which should I follow to achieve this?

the fastest way would be to msm the phone to stock and then update to OOS 12. This will wipe all data from phone.

Flashed r3a1 on my 9 and seems good so far.

Does it work on OOS 12?

NO!

I flashed r3a1 and I am still getting reboots. I get maybe two a day and they happen while playing games.

What games do you play?

 

[Samuel Holland]

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?

Now, I could be totally wrong, but I just thought I'd share what I did this go-around while on this kernel. I went into twrp, flashed the update, and then kernel, w/ magisk. I did have this little issue where at the top of settings, it said app started or something like that, but after updating to official twrp, it now looks normal. Everything has seemed to be okay since then, but I haven't ever tried looking at logs,etc.

I was playing Diablo Immortal closed beta.

Send me a PM if you don't mind.

Yikes, forgot to backup stock partitions of 11.2.10.10 before unrooting to update to 12. Went in bootloop
Always backup the stock partitions as written in main OP, if you jump around btw os

You can visit telegram group, someone makes backups there and share them

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.

You can try Blu_Spark kernal which is Systemless installer (doesn't touch system/vendor partition, OTA friendly) if you want to try another kernal.

Not true. Blu_spark modifies boot and vendor_boot partitions. If you want to be able to roll back, you should back them up first.
