Development [KERNEL] [blu_spark r103 OP9/Pro] [A11 OOS/A12 Custom]

Can you flash this via adb sideload instead? (Im unrooted/stock)

My bad, you can adb sideload spark kernel through LOS recovery. However, I think you need to be rooted.

 

[break.cold]

nope I'm just restoring my device on stag OS

Yeah, It took me couple of hour of experiment in getting spark kernel to get it working, because it keep sending me back to fastboot menu even on LOS 28 June update. I installed it through Fk manager, it sent me to fastboot menu even though I flashed every img files. Then I adb sideload copy.zip after flashing LOS rom and Gapps, reboot to system and reboot to recovery to flash magisk and reboot to system again and then reboot to recovery and then use LOS recovery to flash spark kernel successfully.

FKM worked for me with the attached script right away. I copy.zip prior to the rom upgrade so cant judge on that

 

[break.cold]

Like I said before, that resulted in bootloader loop. However, I used FKM with previous script mentioned after restoring the rom and now it works

I used above method that I mentioned.

I got it to flash and reboot no problem, on latest StagOS. But yest I went thru several different ROMs and sometimes I could flash BluSpark no problem and sometimes no matter if I had flashed it the last time I was on "said ROM" but this time it's wld not boot no matter what I did. I think maybe the problem is, if ur on a ROM w/BluSpark, if u switch ROMs if u don't reflash stock dtbo, vendor_boot, and boot imgs for "said" rom b4 and switching roms that is the problem that keeps u from flashing kernal after switching roms. So now I reflash those imgs, reboot into stock rom(no root, no kernal) then back to BL and then flash the 3 imgs to go into recovery to go to different rom(lol) then once set up and rooted I can flash BluSpark fine.. I am not sure....

Edit/update

Ok, so testing my theory, I went from having StagOS on slotA(I restored dtbo, vendor_boot and boot) and then rebooted, went to BL, flashed new imgs for SparkOS, went to recovery, wiped and adb sideload the new ROM.. after setting up and rooting I attempted to flash BluSpark. I was on slotB, also I had went from one ROM on slotA and now different one on slotB. Forced to fastboot.. I had to reflash Spark imgs, then I went to recovery and adb sideloaded ROM again to get to slotA.. Then I successfully flashed BluSpark!

So for BluSpark to work you either 1) have to be on slotA or 2)u need to have whatever ROM u are on, on both slots..thank you eng.stk for great kernal!! Maybe u can confirm/deny my theory..

No, it works fine in either slot.
The problem is that sometimes both slots aren't exactly well populated and the installer trusts on certain conditions to successfully work.
Both slots should be on latest and exactly the same A12 firmware from stock ROM previously to install anything.
Both slots should be flashed with working custom ROM.

Partitions to restore are the ones touched: boot, vendor_boot and vbmeta, you can do dtbo also. vendor_dlkm is mandatory to be restored and I think people with issues are missing it (flash only is available via fastbootd, not regular fastboot). MOst of the time device is so fast flashing ROM zips, maybe it's easier to do it like that.
We are used to this stuff on the Pixel and you guys are lucky to have already auto logical partitions processing, avb patching and all that jazz. We didn't in the Pixel 6 series initially and it was ruff during some months.

Device needs to be rebooted after flashing kernel and certain conditions met because vendor_dlkm is a logical partition and for it to be active.
Also kernel shouldn't be flashed after anything that touches any logical partition before a reboot (like flashing a ROM zip, restoring partitions, etc).

In stock ROM there's no vendor_dlkm in place, but most custom ROMs, since they drink from AOSP, should be already using it.
Check the Pixel 6 series forums to read more on this.

Can you flash this via adb sideload instead? (Im unrooted/stock)

While is possible, I don't recommend because of what's above.
Even with all the things apparently working nicely, I ended up with issues when sideloading the kerrnel zips from LOS recovery for instance.
Logical partitions are nice to mod kernel installs in , but a pain to work with.

There's the ability to save the kernel flash log to Downloads folder and share it here in case of any hiccups.

It's done by @capntrips , which has been doing quite some work in all this logical partitions/avb stuff we've been talking about, both on AK3 and other mods/solutions.
Highly recommended.

thanks for that, i tried the r96 version on StagOs with FKM and it kept going to fastboot, it worked perfectly with Kernel Flasher

Successfully flashed r96 on StageOs 12 with kernel flasher app

Can you please describe the steps you made in detail & what copy.zip file? Im in a bootloop altough i restored vendor_boot, dtbo and boot images.

It's bit complicated,

Obviously I started with C.48 of OOS stock, I flashed dtbo, vendor_boot and recovery.img files then reboot to recovery.
I flashed copy-partitions-20210323_1922.zip with doing factory wipe/ format.
Then reboot to recovery again, then I did factory and format data, then I flash LOS 28 June rom and then reboot to recovery again and flash Gapps, and again do format data/factory wipe.
Reboot to recovery again then again adb sideload copy-partitions-20210323_1922.zip for LOS to be on both slots just to be sure.
Reboot to recovery but didn't do factory wipe after flashing copy-partitions-20210323_1922.zip second time after flashing LOS and Gapps.
Reboot to system, did system setup. And then reboot to recovery flashed magisk 25.1 file in recovery and reboot to system again.
Again I reboot to recovery flash spark kernel through LOS recovery with adb sideload. Reboot to system. Success...

Still not able to flash this kernel even with the new app. I'm on a LE2127 (TMO OP9P) w/ LOS 19.1 and Magisk 25.1. Everytime I try to flash the kernel, it fails and my phone gets soft-bricked if I reboot. I've been able to recover to stock LOS w/o having to wipe data fortunately. I've flashed C.48 firmware (and the copy partition zip) as well but still fails. I've attached the logs from the kernel flashing app. Thanks.

Edit: I can do a logcat if the app logs aren't sufficient. Thanks.

Dirty flash the rom and start over

Your super partition is dirty. You probably got it while using that copy partition zip.

Growing partition 0
Not enough space to resize partition

Creating vendor_dlkm_ak3 failed. Aborting...

Also got it after use it a couple times. I advise people to stay away from that zip, it misses some stuff we have in newer devices.

Flash OOS 12 in both slots to get proper fw installed.

Go for regular LOS flash in both slots.

Unpack your LOS zip to get img and flash the logical partitions in fastbootd (NOT fastboot)
do it for slot a AND b

fastboot flash odm_a odm.img
fastboot flash product_a product.img
fastboot flash system_a system.img
fastboot flash system_ext_a system_ext.img
fastboot flash vendor_a vendor.img
fastboot flash vendor_dlkm_a vendor_dlkm.img

Thanks for the info - Works perfectly now.
I'll definitely avoid using that zip in the future.

hi, in the changelog says that there are some boost options turned of, how can i activate them ?

Kernel apps like FKM or EXKM.
What boost in particular?

Kernel apps like FKM or EXKM.
What boost in particular?

these ones:

• msm_performance touchboost toggle on/off (enabled by default), tweaked cpu_boost driveradrenoboost ready (disabled by default)
• and could i install this blu_spark r96 in oos 12_c48 ?.

1. Kernel apps like I said
2. read the posts "Custom A12 ROMs only!" So... no.
