I flashed r28 the same way and had no problems. I expect that the bootloop will be gone after flashing the stock kernel via fastboot.
[KERNEL] [blu_spark r63] [A11]
- Thread starter eng.stk
- Start date
Where is the stock kernel ?
should i fastboot flash boot factoryboot ?
i looked through all factory image files and I can't see one called kernel.
Is kernel nested in boot img in factory image ?
While waiting I sideloaded latest factory image and rooted again.
I then flashed r28 again through json import in fkm no worries this time.
Could it be because I wasnt on latest factory image ?
The stock kernel is contained in the file called boot.img. You can find it in every factory image but the version might be different of course. You can flash it with the command 'fastboot flash boot boot.img'.
I don't have enough info to tell you why you got the bootloop.
I would suspect it was because you weren't on the latest factory image. When the new security update comes out you need to update to newest or problems can arise if there were kernel changes between builds. This is why you had bootloop issues.

Yes I'm inclined to believe that was it.
The thing is : I'm running stock with magisk only and though I have been able to ota previous update I didn't have any notification about latest build.
I only learned it once I was crashed this morning.
Thank you for your time. Love this community.
Running well since then.
Thank you eng.
I noticed the latest release says R28 on the link but only offers R24 for download. Am I missing something?
The link posted in the release post does indeed link to r24. However, if you go to the op and hit the link to download it will direct you to r28

blu_spark r12 release (A11)
New build is up!
You can use FKM download kernel feature, just import the link bellow in the app :highfive:
blu_spark_r35 release
FKM download config: HERE
Keep in mind: I will give no active support for custom ROMs (including stock based ones).
I am mostly interested on debugging stuff in stock ROM (with logs and reproducible steps to replicate the issue).
No mirrors please

And we meet again yet on a Goggle device.
Feels like the good old days of the former nexus 5.
Kernel is top notch, full of goodies.
Wasn't expecting this mind blowing battery usage on such a device to be honest, really good.
Snappiness just went wild with blu_spark.
Nothing new there but worth of notice still.
Keep up, it's blu time.

It's been a few years since I've taken a look at kernels. It would be nice if some of the features had descriptions and a brief history. example:
adrenoboost, KLAPSE, KCAL, KGSL, ZRAM Swap (LZ4) and with swap file disabled, FS fsync toggle on/off
The fsync one I've heard of but I read mixed feelings about the benefit/risk. The rest I don't know if they are things random Android kernel modders invented or if they are latent features in the Linux kernel or Qualcomm chips-- I dunno. And when and who came up with making them "a thing we want."
It's been like a decade and I don't know how relevant or if there is empirical evidence they have benefits-- it's just a mystery to me these days.

Is there any way you or someone else could provide an .img of your kernel? I had it installed prior to updating to December and now the magisk (canary) generated boot.img won't boot for me. DIsabled all modules and such before hand.. did the same procedure I've done every time when updating on 11.
I watch the logcat using monitor.bat on my computer of the device booting and it keeps getting stuck in a loop where its looking to set sound related settings. So taking a shot in the dark and seeing if someone can make an .img of the December build of this kernel and see if it will solve my problem.
Edit: Nevermind, fixed it. Apparently 1 module wasn't disabled and I was able to get rid of it during boot.
Thanks for the release!

Adrenoboost boosts the gpu frequency...
KLAPSE is a display driver that auto darkens and adds an amber or red tint to the screen to "reduce eye strain"...
KCAL is color calibration...
KGSL is the trustzone environment for display (IIRC)...
ZRAM is compressed pages is RAM...
Swap is physical disk space masquerading as RAM...
there is typo on FKM config link, i think its should be https://raw.githubusercontent.com/engstk/kernelfkm/master/updater_pxl4a.json
anyway, thanks for the custom kernel!
hey will this kernel work for any device running android 11? i have a oneplus 6 running pixen os if that matters
welp i tried and it didnt work it said uncompatible device
do on terminal or adb shell and post the output:
getprop ro.product.device
getprop ro.build.product
