I'm at Oxygen 2.0.3, can I install AK kernel? Just got my op2, afraid of doing something wrong.
[OnePlus 2 Original Android Development] rockafellor:
Hey welcome to the club.! Yeah it's safe to flash ak kernel. But update to 2.1.1 first, then root, afterwards install ak kernel. To change kernel settings install synapse from playstore
[OnePlus 2 Original Android Development] Dude_Virus:
for me on airplane mode the battery stayed at 100% , left it for 9 hours.
[OnePlus 2 Original Android Development] PhillOS1:
Thanks, im looking into rooting it now.

It says something about 'dirty reflash'? What does this step mean?
[OnePlus 2 Original Android Development] Dude_Virus:
It means flashing the ROM file from recovery but without wiping anything. This is only needed if you were using a custom kernel. If you have a stock device and haven't made any kernel related changes then you can skip this step.

Looking at your previous posts it seems you just got your device and haven't made any changes.

If you haven't then follow below process.

Unlock bootloader ( it will result in entire wipe )

Flash twrp recovery

Root device

Install ak kernel

Install synapse if you want to tweak settings

Follow this guide for the bootloader unlock, twrp and root

I can't do that, just got the phone and am still on stock everything...

Can other people please confirm the problem related to unplugging of headphones and issues with music and calls though please to see if it's an isolated problem?

Thanks

[OnePlus 2 Original Android Development] LiquidSolstice:
No worries! You didn't come off as impatient or needy to me. I usually don't get phones so early into the development cycle either.

AK is a great place to start. It makes OOS much nicer to use until CM gets their fingerprint stuff ready. Have faith, this phone will get pretty awesome in the coming weeks.
[OnePlus 2 Original Android Development] singhz905:
Finally... AK is here.. Best kernel ever.. loved your work for opo and still using it...

[OnePlus 2 Original Android Development] hunhool:
Glad to hear :)
[OnePlus 2 Original Android Development] Micalus:
Could it be possible to get full Kernel Adiutor support with your kernel? i want to modify the screen settings since the display is pretty good but the colors could be a bit more powerful. I also have the OPO running BlissPop Caf version with your amazing CAF kernel and it has the option for all the kernel adiutor stuff. SandyKernel has it already. would be really amazing to see KA support.
[OnePlus 2 Original Android Development] nirmik379kale:
Hes releasing it tomorrow i guess... As he mentioned, some more stuff needs to be done to get proper working on 3.10 kernel i guess...
[OnePlus 2 Original Android Development] LiquidSolstice:
Nothing to do with Kernel Aduitor support. KCAL settings are simply not in the kernel yet. They'll be in the next release (which ak current has slated for tomorrow)

Trust me, I too am greatly looking forward to adding some punch to my colors!
[OnePlus 2 Original Android Development] ak:
UKM is not ready, hours of work to mod it is necessary. :good:

it will be inside but not fully working.
[OnePlus 2 Original Android Development] gqukyo:
It's a google feature and linked to your google acct just like I stated in my previous post. ;)
[OnePlus 2 Original Android Development] CounterC:
I agree. I had very low expectations with all the bad comments and mediocre reviews but it appears I really like the functionality of current OxygenOS + AK kernel.

Fingerprint scanner works like a champ and hasn't failed on me once (even though people say it's slow and bad but I disagree). I really like unlocking the phone with fingerprint when screen is off, every phone should have that!

Now OnePlus has to fix the battery drains in Oxygen OS and we are good to go!
[OnePlus 2 Original Android Development] TheDrgizzmo:
Which is your configuration? I had 51k with stock rooted and ak kernel.

test kernel online

New test kernel, for now only CM:

tuned interactive a bit for performance + fixed all problems with UKM

i have to test if all platform support hw revision v2.1 dtb only (no need to compile for old variants)

tuned: slew-rate as "time in us it takes for the regulator to change votlage value in one step"

Download

thanks a lot

[OnePlus 2 Original Android Development] Dude_Virus:
Synapse seriously has weird issues. Without having made any changes and just waking the device up after a long sleep now it is not letting me control any input boost values. There sliders just don't move, reboot also didn't solve it. Only option left now is to clear synapse days and check.

Update: after clearing synapse data now I don't even have the dropdown to select governors.
[OnePlus 2 Original Android Development] urgali:
Hey @ak, thanks a lot for all the hard work!

..i'm testing out your cm test kernel, working good so far, synapse sticking on boot.

Hey there,

reporting ak kernel test v22 for cm: i've got problems with synapse. Hotplug settings still don't stick on reboot, and almost every option under cpu tab fully reset sometimes.

Already tried reflashing kernel, clearing synapse data and reboot, uninstalling synapse and reboot.

I'm running busybox on rails and deletes msm files from system/etc too.

Am i doing something wrong or is there still some problems?

Keep up the good work!
[OnePlus 2 Original Android Development] Utkarsh-ezzo:
v21 Oxygen - Hot plugging doesn't seem to be working at all, all 8 cores are always up at around 4% CPU load, any body with solution...?
[OnePlus 2 Original Android Development] AnimusVoxx:
Can anyone recommend the best IO scheduler and governor combo? Also fantastic kernel man!
[OnePlus 2 Original Android Development] v7:
There isn't anything 'best'.The best settings depends on your usage pattern and preference.You have to find a good profile for yourself or use the stock governor/scheduler combo.

---------- Post added at 07:05 PM ---------- Previous post was at 06:22 PM ----------

Try to dirty flash Oxy 2.1.1 then flash Ak v21 on top of it.Oxygen is having a lot of bugs,so a dirty flash may solve it.
[OnePlus 2 Original Android Development] Utkarsh-ezzo:
yeah oxy is buggy for sure, but I had already flashed ak on top of everything stock

Flash AK Kernel

Reboot

[OnePlus 2 Original Android Development] rascal0pl:
V18 was ultra fluid, v21 is lagging as hell (even more than my old i9505) :(
[OnePlus 2 Original Android Development] kroizo:
did you dirty flash rom before kernel flash?
[OnePlus 2 Original Android Development] oediv:
did you flash your system again ? you shouldnt dirty flash the kernel

also there are some changes in the cpu input boost settings maybe there is some bug there now after dirty flash

if you are playing games you can also change the governor to performance to get more power
[OnePlus 2 Original Android Development] rascal0pl:
I flashed oxygen again before v21. In games there is no problem, I'm talking about micro lags in UI (launcher etc) which is just horrible.
[OnePlus 2 Original Android Development] oediv:
try flashing system again (with wiping cache and dalvik + system) also uninstall synapse before you flash everything maybe there are some old settings that are sticky in some place
[OnePlus 2 Original Android Development] LOL9988:
Can I flash the zip via TWRP? Or I have to do something else too?? can anyone tell me please?? i Hate battery life on oxy2.1.1
[OnePlus 2 Original Android Development] oediv:
flash it with twrp over stock

if you are on another kernel you need to dirty flash your system and then flash AK
[OnePlus 2 Original Android Development] dannytanky:
I am trying to see if my OPT is suffering from these micro lags as well. Mind sharing what are the micro lags you're experiencing?

Also, I tested it using Antutu and the scores is lower than a stock OPT. Does that mean anything at all?
[OnePlus 2 Original Android Development] urgali:
It depends on governor/scheduler settings. AK already stated that default kernel options are battery friendly, interactive governor as default with battey tweaks.

I for myself use impulse governor with powersave on. Amazing battery life with smoothness (i use phone just for browsing/messaging, not gaming)
[OnePlus 2 Original Android Development] rascal0pl:
I wiped system and cache, then installed rom + kernel + su, and still the same. It occurs especially when something is scrolling (web browser, setting menu, or applications like synapse or play store). I'm reverting to v18, because v21 is much worse than stock kernel (or even Samsung's stock rom for Galaxy S3). The only help is setting GPU governor to performance, which is causing super fast battery drain. And many GPU options are missing comparing to v18.

This kernel was already battery friendly without compromising the performance, now it feels as if I had a android phone with 512MB RAM and mediatek CPU for 20$.
[OnePlus 2 Original Android Development] oediv:
Dont know whats wrong for you :/

I uc to 8xx and 6xx MHz and set cores to 3:2 and dont get any lags(never !)
[OnePlus 2 Original Android Development] Dude_Virus:
I am not facing any lags while scrolling, I am using elementalx governor with only 2 cores online for each cluster. CPU boost also disabled for all cores except cpu0 and cpu4. Gpu is on default adreno plus I have gpu rendering enabled.

The missing gpu options which your referring, have been removed temporarily as based on the previous posts it wernt functioning as effectively.

The interactive governor has been tuned to be more battery friendly and if u check the posts above AK has shared a link on how you can tune the governor. Give that a try and maybe things might go well for you.
[OnePlus 2 Original Android Development] dannytanky:
Hi, may I know how do I set impulse governor with powersave on using synapse?

Guys, regarding OxygenOs ever being open source. Helen has a Q&A right now. I thought I'd ask her this question. here is the response:

Question:

helencan you elaborate on your effort to aid the custom rom community build better Roms for the opt. Currently devs are annoyed by the fact that OxygenOs is not open source and are struggling to implement features like the fingerprint scanner and the laser focus. We can really use your help!

Answer:

Coming from a developer background, I know where you are coming from. However, when you think about it, how many OEMs actually open source their operating system? We want to support a healthy custom rom community, but we also need to work with Vendors if we want to release proprietary code and that's not always an easy thing as from a commercial point of view, it makes little sense for them to do so. We release the kernel and I believe Qualcomm offers a basic device tree for the Android releases. You also have the AOSP. But to really answer your question of how to support a healthy community, I think the best approach is to work with the Cyanogenmod open source community to release a sustainable repo for custom roms to build on top of.

So we should basically go for CM and AOSP roms.
[OnePlus 2 Original Android Development] yarpiin:
Install stock.lernel - wipe dalvik / cache - install ak kernel ( remember about version oxygen for stock rom / cm for CM12.1 based rom) no need to flash UKM already builted in :) now if somehow you get no uci detected in synapse dont panic ;) install terminal emulator open it and type su ( you wille asked to give root permision) then type: uci press enter ( you will get warning info dont worry ) then type : uci reset and press enter then type again uci and enter , go out from terminal emulator and restart synapse should work ;)

This is the same problem I have see with Stonexone phone.

Explained well ... True considerations ... But I think at this point a nexus phone is the best solution for a developer. I don't want to buy a phone with a high price without the possibility to customize it. That's all .... But i think this is my personal problem. Thanks a lot to all for support.

That's the same problem I'm going through now. I sold my OPO to buy the OP2 thinking the customization and development would be the same. Sadly it's not. I'm thinking about buying a Nexus 5 (2013) for the insane amount of Development it has.
[OnePlus 2 Original Android Development] DDHBanger:
I've decided to jump ship. Oneplus have really killed my interest with lack of support for dev community. Ordered a Nexus 6P. Hope to see you again soon @AK
[OnePlus 2 Original Android Development] oediv:
i hope that cm 13 will solve the problem with fingerprint (it should) but still thers laser focus not support.

dont know why they are so agains making the opt like the opo its true they got another base and its also true that other OEM release their source but another OEM is not oneplus with that fanbase for developers and customerization.

hope that they will chage something in the future, i am happy with oxygen OS and AK now but when cm13 and AOSP is ready i hope that i can use that one without losing functionality like on the opo

lets wait and trink tee

*its tee time*

Op2 an OpX are very good phones, but i have an old CM/GOOGLE mentality. i like to buy an expensive phone because i can mod it ... and have all the sources for doing this ... otherwise i can bought an old Nokia an it will be enought for my use case. that's all.
