Development [r26] arter97 kernel for OnePlus 9 series

[l_mike]

Daam, I don't use telegram, so I won't set up new account only for that. Will try to flash stock 11.2.9.9 via adb when I come from work.

-- update --

Did it differently - installed twrp, than flashed 11.2.10.10 dowloaded with Oxygen Updater, than flashed Magisk and flashed kernel with twrp.
Everything seems to be working fine with newest update. Took me like 5 mins.

I was going to try twrp anyway, so I had a good reason to do so

Which twrp did you install?

Worked for me very well.
Although I don't know if this update is worth all that work

Ok, so I've made a mistake not backing up files overwritten by this kernel. I can't install new update released today and downloaded with oxygen updater.
I thought all files would be overwritten by the updated but it seems they won't. Haven't had that problems with omega kernel.

download the newest full os update via oxygen updater and use local upgrade and that will restore those partitions along with updating to 11.2.10.10

Nope, didn't work for me. Had to install update with twrp.

hm that's strange, if don't mind can you share what happened and what error you got when you tried to update via local upgrade? also, you flashed through latest twrp and had no issue?

 

[l_mike]

I don't remember the exact notification, but it was something general like update failure (may differ cause I'm translating from Polish). Update was breaking at 0%. Downloaded twice to be sure.
With twrp it flashed but I got partition errors at the end. Tried to boot up, but it was booting for like a half hour. So I booted up to twrp again, flashed arter's kernel, than Magisk (thought I might need it) and restarted to system without any problems.

hm damn man that's strange, bc I always do that when I have arter's kernel to go back to stock. I haven't tried to update to 11.2.10.10 yet but I hope I don't have that issue, bc I'll have to payload dump vendor, dtbo, and boot out of 11.2.9.9 and reflash them if I run into that, but that's cumbersome and why I stick to just flashing a full update. did you try flashing 11.2.9.9 via local upgrade first or only try 11.2.10.10?

 

[l_mike]

I had omega kernel till 11.2.9.9 and always performed local update with file downloaded by Oxygen Updater without any problems.
11.2.10.10 was the first update I've been doing on arter's. Thought it will set everything back to stock, but it seems it will not. I am curious if you get more luck with it.

yeah same thing here man, always use local upgrade to get back to stock. I'll let you know if I do but hopefully not lol

I think u need to restore the stock kernel so u need to restore partitions. Next u can update and reflash the kernel. If u not backup search in this thread.

I just came here to ask for help with this.

I'm on TMO and I'm unable to install the latest OTA as well.
So, I tried installing my backup of the stock boot_a.img and boot_b.img.
But, the phone just gets stuck on the pink TMO boot animation and never finishes booting to the OS.

I'm new to OnePlus and this kernel.
What am I doing wrong?

With this kernel, don't forget about the dtbo and vendor_boot partitions. This kernel flashes those so taking the stock ones and flashing will get you back to stock along with boot(kernel) of course.

I can confirm that updating to 11.2.10.10 from 11.2.9.9. doesn't work.
And installing 11.2.9.9 again also fails.
The Error message of the Local Upgrade is: Error installing the system update

I did backup my partitions before flashing arter's kernel with the app Partitions Backup. But unfortunately restoring the partitions with Partitions Backup doesn't work. It says successful but nothing changes (after rebooting).

Looks like the only way to upgrade is TWRP now...

fml, updating via local upgrade is how I've done it for years, and I can't believe that flashing arter's kernel breaks that option. I knew that this kernel touches dtbo, vendor, and boot but I the fact that it now breaks the ability to reflash my oos to get back to stock just ruined my day. so is flashing full oos with twrp working for anyone? welp, I'll have to fastboot flash those partitions from a payload dump. anyone can chime in to let me know if I need to fastbootd flash vendor_boot and dtbo, or can I just fastboot flash all of them?

@r4p70r @thirtythr33 @l_mike There is another way via fastboot (provided of course you have the backup files). That's what I did yesterday with the help of others.

Be on 11.2.9.9, then do the following while in fastboot:

fastboot flash boot boot.img (this should be stock 11.2.9.9 kernel)
fastboot flash dtbo dtbo.img
fastboot flash vendor_boot vendor_boot.img

You'll boot into unrooted 11.2.9.9, then you can local upgrade to 11.2.10.10 and re-root.

If you're unsure about the slot, do fastboot getvar current-slot, then flash the correspondent commands/images accordingly.

By the way, the "Partitions Backup & Restore" app from play store does backup both slots for each, which puts your mind at ease when you do, so you get "dtbo_a" and "dtbo_b" and so on.

it do backup well, bet when need to restore, this app just cant do it.
Also, as mentioned earlier restored vendor/boot/dtbo, upgraded localy, with twrp flashed magisk, and flashed arter kernel in FKM. For now it is the easest solution, and all app data saved

Yeah, restoring via fastboot is reliable. And it's basically the same steps: Restore, then upgrade locally, then for root you can either patch the kernel or flash Magisk via TWRP.

I only went for the kernel patch option because I was too paranoid to flash TWRP and risk losing my data. Is it safe to flash it without wiping anything?

no need to risk, do not fastboot flash twrp.img, just boot it for once and last time - fastboot boot twrp.img

I went into fastboot, then temp-booted twrp with

$ fastboot boot twrp*.img

Then used dd to restore the partitions (also backed up with dd). Rebooted to system, upgraded using downloaded full OTA.

Worked like a charm. No need to install another app for something you can do with a built-in command.

Will it work on color os 12 china stable build?
