This is in alpha stage.

So far tested by [MENTION=8253606]RayInkube[/MENTION] the first brave tester for this new kernel. Many thanks to him

"I've removed the case and the screen protection for be sure before posting here, you want me now to flash CleanSlate and try if i have the same strange issue? You can quote me on alpha thread and we can keep going with testing ahah"

Please try again, yes, hopefully it's something that will be already gone. I don't think that the proximity sensor should have changed between op8pro and op8t to be honest.

I don't see signs of that in the kernel source drop... no calibration files or anything that might have an effect.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] RayInkube:
Already flashed, now is all fine.. dunno what is happened but it was completely broken, now is working flawless.

So far, all i've tested is working fine, on configuration app too!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:
Excellent news! I've since checked the stock config.gz you provided, and the only interesting change is that now the OnePlus Freezer kernel side feature is not set, meaning that it's not present anymore on OP8T. I'll need to clarify if this was done on Op8Pro as well. If so, I think the installer zip can be fully unified between the Op8T and Op8Pro, as all things seems to work on both models. :good: :)
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] RayInkube:
If is possible to unify will be more easy for you to give support on both devices for sure.

Tell me if you need something more, meanwhile i will do my best for test everything possible and i will post battery life after some days of use. :good::good::good::good::good: BIG DEV :cool:
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:
Well, just poke around in the config app, and see how it goes.

As for battery life, you could try to play with Dynamic Boost EAS or Battery saver, but first I think just go with stock settings in the Config app in those parts. :good::good:

Where do I find the img file?

The download on offer is for kernel managers that seem to be root-only, and I'm trying to go rootless.

Oh, also, the suggested backup (boot img) doesn't seem to be available on OP's website yet?...

Thank you, tbalden!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:

Yes, I still need an op8t specific stock boot image.

For now only the installer zip is there.

Do you have a link for the full firmware zip for op8t? I'd download and extract the boot image.

I found one bug after active backlight dimmer option, brightness goes really high after lock the screen

Here is the video showing the bug :

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:
Interesting, well it looks like that on lock screen much lower brightness values are set by the framework and it got very much screwed up the algorithm I apply. Probably needs fixing on all variants.

Can you please do this: scan thru the highest brightness to the lowest while screen is normal on and grab the dmesg. I'm curious what's the lowest/ highest values sent by the framework.

Thanks!

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:
Thanks.

Seems 30-2047 is the range then while screen is on. This differs from the op8pro range it seems by quite a lot. It can already go much lower.. Seems that OnePlus managed to fix the display issues on the new hardware of op8t, somewhat lower values are being set.

I'll have to adjust this a bit for op8t to work correctly.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] RayInkube:
Yeah when i was with 8 pro i've claim refund to amazon because bad display, clouding and green tint, on 8t everything is good, no clouding or green tint on low brightness. :D
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:
Are you using dimmer solution of OnePlus? Seems like there's a new method for lower screen brightness levels. Also new display mode setting called dimmer by OnePlus in the Kernel as well
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:
Hmm, the config app needs some rewording I think. You don't need to place hosts files on Op8t, it's included in the kernel. Just enable the feature, force close chrome etc..and it should block ads.

The result is this:

View attachment 5123451

I'll check the code, but min level in this case was cut at 8.

So it looks like you set it to 8 in this last case?

And there's little difference right?

Maybe this new dimmer is doing something differently and so this dimmer for this model doesn't do a big difference.

And finally, thank you for bringing kernel development to kebab a.k.a OP8T!! Much appreciated :D

[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] RayInkube:
Sometimes after i lock the screen and the display goes off is impossible to unlock the device.

( Screen goes completely black and all the keys not responding, need to force reboot for fix )

Dunno if is kernel related problem and is already two times that happen to me.

I'm trying to understand how to replicate this bug.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:
Well, I'm not familiar with exkm notifications, I really love it's capabilities to flash anykernel zips, like cleanslate, but that's all I usually check with it.

I always flash my devices with boot images from fastboot, and most of the time without magisk. The intention is to provide a very clean way to get some of the most interesting features available thru the kernel, and so not rely on an installed magisk which causes in some cases issues with some apps that try to check for safetynet and no root/magisk.

On op8 variants, one thing is still not resolved and that is hiding the unlock status thru kernel side features. All other supported devices with cleanslate has that, and passes safetynet too.

On op8 it makes fingerprint sensor not working when modifying boot params. At least on Android 10 that was the case. Haven't yet tried with android 11, but I just might bake a test version for someone to try, it there's interest.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:
Do you have block power button when in pocket feature set? If the companion app is killed in the background, it could stop reporting that proximity is left, and then you might have this, unable to use power button.

I recommend to either remove companion app from any battery optimization or hibernate, freezer function if possible, or turn that feature off.
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] theincognito:
I am interested. If you do make a test build, I will test it!!
[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] tbalden:
Great! It's a slight change in the kernel in the boot commandline part. Replaces a few androidboot params to make it look it's locked.

I have baked now a zip and a boot image too:

Installer 2.4.3 test version: https://www.androidfilehost.com/?fid=10763459528675571121

EUR 11.0.1 boot image, 2.4.3 test version: https://www.androidfilehost.com/?fid=10763459528675571122

I recommend to just temp boot the image from fastboot (will mean no superuser while that runs, but restarting the phone will revert to your normally flashed kernel):

fastboot boot xy.img

Then try fingerprint sensor, then try Safetynet Attestation (either magisk or I like this one too: https://play.google.com/store/apps/details?id=com.scottyab.safetynet.sample&hl=en )

EDIT: well, now I've realized that you cannot test with Magisk Manager safetynet check. Magisk manager needs to be uninstalled theoretically, otherwise safetynet will be tripped. So it must be another app. After the test, you can reinstall magisk manager.

Fp sensor is broken after install 2.4.3

That was fast. So SafetyNet passes, but FP is derped. "Fingerprint hardware not available". That's the error message on screen.
