The zip should flash now. You'll have to try and let us know if everything actually works though.
[OnePlus 9 Pro] mattie_49:
Bfq is stock setting. Those are all stock io schedulers though.
[OnePlus 9 Pro] infamousvincci:
Is there any specific functions that you want me to test after flashing? I did a back up of my boot.img using ex kernel manager. Idk if that will help me in case it breaks something lol.
[OnePlus 9 Pro] mattie_49:
Use kernel manager and backup stock kernel as well. This way you can restore stock if it's not functioning properly.
[OnePlus 9 Pro] infamousvincci:
Flashed fine on tmob op9 variant. Ill talk to you in TG lol
[OnePlus 9 Pro] Flasher8:
But mine not bfq default.. should I change to bfq?
[OnePlus 9 Pro] mattie_49:
Test all and change to your liking !
[OnePlus 9 Pro] eng.stk:
People reported working on regular OP9, if that uses simialr OOS bins etc should work.

Keep in mind that I can only test in OP9 Pro (EU), so backup your stuff and procede with caution.

We'll never know what'sreally going on on that "special" models.
[OnePlus 9 Pro] eng.stk:
Stock is bfq, that is my setting.
[OnePlus 9 Pro] eng.stk:
There's not really much difference in IO schedulers for fast nand devices.

in 5.* kernels with MQ framework and assynchonous stuff like io_uring in place (don't know if android takes advantage from this), none is actually advised for nvme and fast ssd, device.

Controllers are robust enough and there's plenty of cache to manage requests, just remove the middle man.

For now I'll keep it like that for some more interactiveness and safeguard, it seems like some userspace crap pegs on IO stuff so there's that.

I will add nothing more on this regard.
[OnePlus 9 Pro] eng.stk:
There's nothing wrong with the install, so follow the troubleshoot steps I posted on release post.

how to flash kernel r100 on Nameless
[OnePlus 9 Pro] Stogie87:
Hi there. Somehow this kernel breaks vibration for third party apps on ricedroid and other custom roms in the forum. Would it be possible to fix this?
[OnePlus 9 Pro] Mr.Conkel:
Is vibration broken all together or just in certain applications? I don't think the Kernel can control that. Vibration would either be working or totally broken.

He's using LineageOS and the rom your using is based upon Crdroid (Crdroid is also based in Lineage) so you could look at the changes and what exactly is occurring to attempt to fix it. But more than likely its probably the individual application rather than the kernel. I use Crdroid here and it works great
[OnePlus 9 Pro] mattie_49:
Using r103 on Lineage 8/7 nightly. Installed perfectly with supplied kernel flasher a page or so back. Fkm ,I tried numerous times it aborts trying to resize a partition. Breaks build. Great work phone feels diff after fresh kernel.
[OnePlus 9 Pro] Stogie87:
Is latest kernel not compatible with C62 firmware? Because I can not flash it on crDroid.
[OnePlus 9 Pro] xontax:
Really? Worked for me on a clean cdroid and op9. Flashed in recovery
[OnePlus 9 Pro] Stogie87:
That's interesting, because i get an error, if i try to flash it via EXKM.

I also did a 100% clean flash of crDroid. I flashed the Firmware for Europe.

Unpacking ramdisk always fails.

#update: Seems like you can flash blu_spark on crDroid only via recovery. If you try via EXKM oder FKM it fails and does not boot anymore. I had to reflash dtbo, vendor and boot image again via fastboot to make it work and then i flashed the kernel via recovery without issues.
[OnePlus 9 Pro] xontax:
Happy that everything works now
[OnePlus 9 Pro] reffu:
Manged to install on newest nameless for OP 9 (20220814) through recovery.

First time I tried via FKM, and it didn't give me any errors, but then hit Qualcomm Crash Dump Mode every time.

After re-flashing nameless, I tried flashing via nameless recovery and that worked fine without issue.

[OnePlus 9 Pro] Stogie87:
Just like flashing magisk in recovery.
[OnePlus 9 Pro] BKZAMAK:
blu-spark version?
[OnePlus 9 Pro] reffu:
Whoops, forgot to specify. This was for r103. it sounds like Kernel flasher would be the better choice going forward, rather than recovery, though.
[OnePlus 9 Pro] BKZAMAK:
stock kernel codered nameless20220814 Isn't that good?
[OnePlus 9 Pro] reffu:
Stock kernel wasn't bad, but I found blu_spark to be a little faster and have better battery life.
[OnePlus 9 Pro] BKZAMAK:
Thank. bro
[OnePlus 9 Pro] BKZAMAK:
Fastchange no problem?
[OnePlus 9 Pro] eng.stk:
You can change slowly also 😅
[OnePlus 9 Pro] BKZAMAK:
nameless version 12.1r11 use kernel blu spark r91 - r100 change slow sometimes

I can warp charge just some times have to unplug then plug back in before it start to warp charge
[OnePlus 9 Pro] BKZAMAK:
Sorry Fastcharge lol
[OnePlus 9 Pro] AaronPusteButz:
I'm only getting "unsupported Android version..." flashing dtbo, vendor and boot also didn't help :(

EDIT 2: Stil rebooting straight to recovery even after flashing dtbo, vendor and boot. Seems like I'll have to dirty flash crdroid again.
[OnePlus 9 Pro] eng.stk:
A little search could get you up and running, already been discussed...

boot, vendor_boot, vbmeta flashed in fastboot

vendor_dlkm flasehd in fastbootd

Or just dirty flash Your ROM ofc, whatever is faster for you.

I don't touch dtbo on this kernel.

Don't use recovery to flash, is in the release post! Results may vary.

Use Kernel Flasher instead (given your ROM is compatible, which may be not). This is meant for LOS 19.1.

Also, other kernel apps flashing is still not compatible with latest ak3 changes.
[OnePlus 9 Pro] mattie_49:
Using 103 on pixel extended for lemonade.!! Build absolutely has to be on slot a to successfully flash. Props @eng.stk
[OnePlus 9 Pro] .DeluXer:
I use lastest StagOS.

After flashing Kernel on Slot_a through Kernel Flasher Device needs very long to boot.

After boot I only see Lockscreen. Touch is not working.

[OnePlus 9 Pro] Wickidmasshole:

[OnePlus 9 Pro] mattie_49:
Kernel flasher but build has to be on slot_a or it will break during installation. Dev check or fastboot getvar ,either will tell you active slot .
[OnePlus 9 Pro] Vmo x:
That's because stag has not updated to c62 yet.

You can flash it with adb side load and without root. I tried it on Pixel Experience and Nameless. But like Post #14 says, you won't get all the features from the kernel.

[OnePlus 9 Pro] Vmo x:
I'm not sure if its ROM related but when I flashed on op9 through kernel flasher, I have bug where power button does not function, but on other kernels power button functions but alert slider doesn't?, any help would be appreciated, I'm on CRdroid 12.1

Fixed Edit : It was ROM related. Updated now working fine.
[OnePlus 9 Pro] alb94:
Did you flash by recovery (adb sideload) or FKM ?

Edited: I got it through FKM.

[OnePlus 9 Pro] z00man:
same problem here in stag..actually slider didnt also work at all anymore ..had to revert stock
[OnePlus 9 Pro] Stogie87:
No issues here on ancient rom with latest r106. Alert slider works and everything else.

StagOS has also problems with requiem kernel. So it is rom related.
[OnePlus 9 Pro] Mr.Conkel:
I had a question about the OOS11 versions of this kernel, do they modify the same partitions as the current OOS12 custom releases? (Being vendor_boot, vendor_dlkm and boot imgs). This way when flashing I know what to back up if I wanted to revert my kernel.

Also has anyone ever tried to flash these versions on a custom rom, I know it wouldn't be supported but what would be the drawbacks if it booted in the first place?

Thanks for any answers, cheers!

Not fully, there's changes that are incompatible, already posted by other users.

I only recommend running this on LOS based kernel running ROMs.

"A12 custom" on the title means that on Android 12 it only works in custom roms and not in oxygenOS?

If you want to stay on stock, no need to complain. XDA is for development and custom development. Now, on the other hand, blu is barebones of what it used to be for omeplus devices. You aren't missing much. Almost all features that once was in blu is gone. Not bashing dev, just stating

[OnePlus 9 Pro] eng.stk:
A12 is EOL.

Starting r120 is for A13 custom ROMs liek LineageOS 20 and the likes.

For A12 ROMs stick to previous kernel versions.

We don't need to worry about vendor level atm. WHen we do, I'll update like always.
[OnePlus 9 Pro] alb94:
Crdroid v9.0 + r120 Second battery cycle after flash... This is insane. I'll test it for more days, but so far I've never had anything like it in terms of battery drain and duration. I say this based on my use, which is social networks, YouTube... Congratulations.

[OnePlus 9 Pro] osm0sis:
OnePlus doesn't care about the community anymore (closed dev program, incomplete/broken source, removed decryption in stock recovery, removed advanced reboot, the list goes on...), so why should the community care about OnePlus? Support for custom ROMs is absolutely the only way to go here.
[OnePlus 9 Pro] Alberhasky:
Got it, I appreciate your answer @osm0sis . Do you have any recommendation as to what custom ROM to use for OnePlus 9 Pro?
[OnePlus 9 Pro] osm0sis:
Just my opinion, of course!

I personally use Lineage 20 with MindTheGapps, Magisk Canary and several modules (mostly my own, plus root hiding), blu_spark, Lawnchair Dev and MCG GCam.
[OnePlus 9 Pro] mattie_49:
Even though you can't switch recent provider to lawnchair yet? It doesn't lag . That's my setup but without lawnchair because it was 12.1 and couldn't switch through quick switch.
[OnePlus 9 Pro] osm0sis:
Yeah decided I'd put up with Trebuchet as Recents until Lawnchair starts publishing builds from their 13-dev branch since I really wanted to jump onto Lineage 20. Doesn't seem too bad!

[OnePlus 9 Pro] mattie_49:
Just curious? Since 1/1 build I've been experiencing data falling out /dropping. Me not noticing and leave wifi at the house and have no signal. Then 5-10 texts coming through all together randomly. Was just asking because I flashed from A13 stock this last time and maybe that's it. Didn't roll back to C-66 prior.
[OnePlus 9 Pro] osm0sis:
I notice RCS was getting stuck as "Messages is doing operations in the background" or something like that, but force closing Messages and opening it again resolved it and all the RCS messages came in. I joined the Carrier Services Beta to see if it helps, and so far I think it has.

Android Auto is also a little flakey and needs a reboot once in awhile. Apps in 20 definitely feeling a little buggier than 19.1, but I'm still not regretting the upgrade.
