hey after i change file system data and cache to f2fs , its end with error that said "unable to mount '/system' '/cache' '/data'

am i doing it wrong ?

i just change the format from twrp v 2.8.7.0 . my phone is 4/32 2.3 ghz . need help thanks :D
[ZenFone 2 Android Development] Ksagrande:
Using this kernel, with underclock, and the battery life is amazing. So, thanks a lot! A few things I've noticed is that yankactive and TheSSJactive are performing worse for me than interactive. Also After using sweep2sleep today and it worked perfectly for about an hour, after it whenever I use sweep2sleep, it turns the screen off but then quickly turns it on again in the lockscreen.

I'm using a Ze551ml 4gb/64gb

The issues don't bother me at all, just giving you a feedback. Thanks for the hardwork and for making my battery life last a full day!
[ZenFone 2 Android Development] dahikino:
It seem after reboot, if i take too much time to enter my login code (pin) , the screen react and come back to turn on but the keyboard no react, it 's impossible to enter something, the only solution is to reboot the phone on ZE551ML

Another thing, when i use the app Clean Master with the feature "Clean unnecessary files" the phone hang and reboot after 20 secondes, it never happen with stock kernel.
[ZenFone 2 Android Development] dahikino:
Why the cpu can't have the 4 core go down at the minimal frequency at the same time? , only 2 cores go down or the n°1 and 2 or the n°3 and 4, never the 4 cores in same time ?
[ZenFone 2 Android Development] Dan_Jacques:
What your settings? What gov?
[ZenFone 2 Android Development] Tiongkia:
I can only get 500mhz as minimum. How did you get 300mhz? Thanks for sharing in advance.
[ZenFone 2 Android Development] ImjuzCY:
I use the OCUC version
[ZenFone 2 Android Development] Tiongkia:
Ok. Thanks buddy. Let me try
[ZenFone 2 Android Development] dahikino:
I use default setting in adiutor, with thssjactive governor I try with standard version and oc version!

I mean v91 on ZE551ML

I do not know much about kernels , then , this is the first Iflash , flash and is so ready? or do I have to do anything else?
[ZenFone 2 Android Development] JuanMnz93:
Can someone help to set good setting in order to reduce the time which my phone open apps and to avoid that the phone close apps when I use another one. For example, I use WhatsApp and Chrome, when I open Bbm and the camera (for example), chrome is closed by the system.
[ZenFone 2 Android Development] Dan_Jacques:
I think there is an app that is turn these cpu cores busy.

I suggest you to download Gsam or another app that diagnose juice usage by the apps, and check the app that is consupting the processor power. TheSSJActive is great for power saving, and put the cpu cores in the lowest freq even is possible, and I think the kernel isnt the problem.
[ZenFone 2 Android Development] Phoost:
The only reason for me to unlock the bootloader would be this kernel.

Thats the reason why I'm asking.

What are the main advantages of this ?

Speed isn't a issue for me. Zf2 is just fine with stock.

Memory manangement, battery etc ?
[ZenFone 2 Android Development] albertorodast2007:
Use kernel auditor, go to "Low Memory Killer" tab and reduce memory profile to light or vey light , check apply in boot and reboot. This should help as the system will start killing applications until that amount of free mem is reached. Stock values are a bit high, especially with a device that has 4Gigs of RAM. There are other apps to control this, search for LMK on the GPlay Store.
[ZenFone 2 Android Development] ImjuzCY:
By stock I always have around 600mb+ free ram and with very light I have 300mb free. I'm not those who will always be annoyed by less free ram, I like full ram because it means quick app launch.

But Very Light is too much for me. I have 300mb free ram and when I launch Snapchat it reboots. Possibly too little free ram. I think the settings should be tailored to personal need instead of using the preset values.

I have 4GB ram version.
[ZenFone 2 Android Development] baonxxx:
Is this kernel support if im not root my phone yet? I have bootloader unlocked and twrp installed
[ZenFone 2 Android Development] gsser:
questions everywhere

Hey guys im new on asus forum. I will buy ze551ml 16gb 1.8 version in turkey. I dont understand zenfone 2's rom development. So if i flash this kernel to it how will it effect the device? Are there any bugs or not working functions, battery drain etc. And i would like to oc it from 1.8 to 2.x(3)... Can some one explain these things to me? Bootloader unlock etc.

Best regards
[ZenFone 2 Android Development] Zetsubou Sensei:
You're able to flash the kernel but if you don't have root you can't change any of the default settings on the kernel as that would require root access.
[ZenFone 2 Android Development] ImjuzCY:
If you cant even find these info by just searching, you really shouldn't flash anything not even this kernel. Really. You're risking too much if you don't have basic knowledge like that. Go do some research before doing anything dangerous like flashing.
[ZenFone 2 Android Development] baonxxx:
Ahahaha i already root my phone , one question , is it okay to turn off 2 core and only use 2 core?
[ZenFone 2 Android Development] ImjuzCY:
Yes you can but in my experience disabling two cores aren't worth the battery gained in exchange of performance drop. Underclocking is a better way to save battery. I use 1.25Ghz all 4 cores and no noticeable performance drop with all day battery
[ZenFone 2 Android Development] hcarrega:
Can i use your Kernel in crdroid?
[ZenFone 2 Android Development] DeeJayhX:
Forgive me, I read the first couple of posts thoroughly, but I am quite ignorant on custom kernels. Can I configure anything myself? Such as choosing the profile for the CPU? Or is this just plug-and-play flash-and-go? I've already flashed it (using ROM SuperZen, basically debloated stock ROM, playing nicely so far), but have no idea how to configure any of the options. Unless the only configuration that can be done is with an init.d script (which I'd be ok with I guess, were there any documentation)

Thank you so much for all your works, always excited for TheSSJ releases :)

EDIT: I see now that I needed Kernel Adiutor, although it was mentioned a few times, to someone with little experience like me, it just seemed like misspelled terminology. If there's anything else I'm missing feel free to let me know :D Thanks again!
[ZenFone 2 Android Development] Gabb96:
Thanks for your awesome kernel!! 5 and half hours of SOT
[ZenFone 2 Android Development] Lorka.Tinou:
You charged a bit your phone before this screens so not really 5 and half hours SOT, but still it's really good.
[ZenFone 2 Android Development] maor23:
i got question

i do i unlock my bootloader?

i should have a other ROM on phone or i can unlock bootloader and still be with the original ROM and with this kernel?
[ZenFone 2 Android Development] krasCGQ:
1. Yes (must ;)).

2. Stock or stock-based ROMs.

Sent from my ASUS_Z00AD
[ZenFone 2 Android Development] maor23:
i dont understood..

lets say i got SD CARD and i got CM rom download(not rly, just a exapmle). so i need to put the cm rom zip on there and just after it install the bootloader i need install the rom or can i be without any rom in one of my card and after i unlock my bootlader i can reset the phone?
[ZenFone 2 Android Development] Lorka.Tinou:
To use this kernel you need and unlocked bootloader, and then you can stay with original Asus stock ROM, or use a stock-based ROM such as SuperZen or Prism.

You CANNOT use this kernel with CM or other custom ROMs.
[ZenFone 2 Android Development] maor23:
what the diffrence beetwen the OCUC to other project t?
[ZenFone 2 Android Development] ImjuzCY:
Well, the presence of OC and UC is the only difference. The OCUC version clock speed ranges 300-2500Mhz while the normal have the stock clock speed of 500-2300Mhz
[ZenFone 2 Android Development] maor23:
where i get kernel auditor?
[ZenFone 2 Android Development] ImjuzCY:
Play Store. And btw it's Kernel Adiutor
[ZenFone 2 Android Development] maor23:
who can help me pls? i got big battery drain, in GSAM it write that it beacuse the Kernel.... what can i do?

---------- Post added at 04:52 PM ---------- Previous post was at 04:13 PM ----------

someone can give me his setting from kernel adiutor?

my battery drain too fast
[ZenFone 2 Android Development] ImjuzCY:
If you did some research, everyone is facing the same problem. We're all having Android System which is the kernel on the top of battery draining list. But still we can get 5h or so screen on time. All you can do now is don't look at it and forget it and use your phone like nothings wrong. We can't do anything about it until Asus sort it out.
[ZenFone 2 Android Development] maor23:
so its not beacuse this kernel? this a known system problem?
[ZenFone 2 Android Development] ImjuzCY:
Yes there's nothing we can do.
[ZenFone 2 Android Development] zam3da:
Hey.. Thanks very much for your hardwork. I really love this.. What i want to ask is why f2fs is didn't work for me? I have already format it with ssj twrp but after reboot it is just stuck in logo asus, the i try wipe chace dalvik and it is done to start but shows text "decryption was unsuccesful". So i format it again with ext4 and it functionally normal again after reboot.. Pls give me solution for this. I use z008D device, i use kernel who ported by ciffe54 for 550ml. My firmware is .88 tail number
[ZenFone 2 Android Development] :
i flash the latest ocuc zip and mine feq 333 to 1833

[ZenFone 2 Android Development] zam3da:
Download kernel adiutor on playstore. And grant root acces with SU. Then in tab cpu, set the freq clockspeed what u want and u can also set another feature in kernel adiutor.

No more updates?

By the way, i tried both normal and oc uc version. Same settings. Normal version seems more battery saving, more sot.

KVM Version Request

[MENTION=2388665]TheSSJ[/MENTION] - would it be possible to request for a copy of your kernel with KVM support. I don't mind the performance impact as others have reported.

I'm interested in trying QEMU, BOCHS or any other OS emulators out there to run at least windows 95 or 98. :)

Hope this is not too much to ask...:fingers-crossed:
[ZenFone 2 Android Development] maor23:
hey guys

when i change something at kernel adiutor and do apply on boot, and restart my phone, this not apply... why this happening?
[ZenFone 2 Android Development] gmanhad:
Go into settings , under auto start manager , and select to allow kernel auditor to start on boot.
[ZenFone 2 Android Development] ber31inger:
Dear team,

I am using this kernel with the SuperZen ROM and there are absolutely no issues at all...but I am looking for more battery life :( Its ok now, but need more :) Is there any way I can get more juice please? What are the recommended settings in this kernel to use to get more battery? Thank you very much in advance
[ZenFone 2 Android Development] ImjuzCY:
Set maximum clock speed to lower values. I use 1250Mhz as maximum
[ZenFone 2 Android Development] ber31inger:
thank you...anything else please? like which governor to use + i/o? appreciate your help
[ZenFone 2 Android Development] ImjuzCY:
I use all defaults settings other than clock speed. If you want you can use thessjactive governor for cpu
[ZenFone 2 Android Development] Zetsubou Sensei:
Jesus, what kind of SoT are you seeing?? I'm running the OC/UC so 2500 for max and 300 min and I'm getting about 3.5 hours of SoT over a 12 hour day which I think is excellent!

Also, thank you for the development on this guys, its an excellent kernel and is very stable. You're hard work is really appreciated.
[ZenFone 2 Android Development] ImjuzCY:
I'm on OC/UC version with 300 min 1250 max. If I'm on wifi all the time I get around 5-6 hours SOT. If on mobile data it's not constant around 4 hours

How is the gaming performance with this kernel ?? Does Asphalt 8 lag ? cause it lags on 2.20.40.97.
[ZenFone 2 Android Development] Zetsubou Sensei:
Not sure about that particular game but the ZF2 gpu isn't the best, totally blanking on the name of the processor for the high end one. It's a mid grade chip. Don't expect 801 levels of performance like I did :/
[ZenFone 2 Android Development] dahikino:
Seen bench, powervr g6430 out perform about 30% the adreno 330 gpu,

www.tomshardware.com/reviews/oppo-n1-smartphone-phablet-cyanogenmod,3837-12.html

Problems of performance in game Playing do not come from gpu, but by x86 android platform integration
[ZenFone 2 Android Development] mickey36736:
Depending on temperature. When gpu reach high temperature, it will start throttling.

That's why the game lag. I tested with gamebench.

At first, fps is really stable (30fps) but after a while it start to lag because lower gpu clockspeed. (around 25 fps)

Read more about gpu throttling here. http://www.tomshardware.com/reviews/asus-zenfone-2,4267-9.html

Does this works on stock or just cm?

My phone was 4g of ram
[ZenFone 2 Android Development] Tiongkia:
development stopped? :(
[ZenFone 2 Android Development] sTIMulat3:
It's only been a month and a half, I've seen things go for far longer between updates. The developer probably has other things he has to do in his personal life that he does not need to tell us about. So don't worry! :)

[ZenFone 2 Android Development] abner albuquerque:
hello this is the first Kernel I flash on my smartphone . I do not know anything about kernels , but I know he will help me to save battery power , then how active this function to save battery power ? please help me ,
[ZenFone 2 Android Development] SBFarooq:
well nothing to worry about!

first, always read ahead of what you are about to do, you have flashed something on your phone without knowing what it is used for may lead to damages later on! anyways, now that you already have this done, I would recommend downloading Busybox installer first and then kernel Auditor from play store.. once you have done the installation, then open kernel auditor and go into CPU settings ... there you would find the profiles which determine how your CPU would act in different conditions .. for batter battery just select the thessjactive and in the I/O section (which determines the memory utility) select sioplus ...

you might not feel any difference immediately but give it a few cycles ... I get around 5 hr+ SOT with 20 hr standby on dual sims on my Z00A ... which is good enough for me ... but again ... i would recommend that you read about such things on your own as what I or others might tell you might NOT always be what you are looking for!
[ZenFone 2 Android Development] abner albuquerque:
thank you so much SBFarooq. so one more question for the alterations take effect , I have to leave the option "apply on boot" activated ?
[ZenFone 2 Android Development] SchinTeth:
Anyone else getting bootloop with this?

I flashed it with BLiss Rom by flashing the .img file via fastboot and by flashing the zip file with twrp and both of them keep showing the "upgrading apps" screen and then go back to Bliss splash screen.

Interactive Governor Report

Interactive is working either at full speed (1.83 MHz) or at Deep Sleep. Nothing in between
[ZenFone 2 Android Development] TheSSJ:
Interactive is the governor I used from the stock source, nothing changed there.

New version is up (v29, it's a streak!): Move governors:

Ondemandplus

Yankactive

Adaptive

I didn't forget about lulzactive and an automated hotplugging mechanism, but I need to stop for today...using yankactive now and it's working okay (as it is just interactive gov with some changed specs)
[ZenFone 2 Android Development] lordpipa:
On v29 I've flashed but none of those Governors appear. Also the build says July 12.
[ZenFone 2 Android Development] Ntrasme:
I sometimes have this problem on stock kernel. It happens when you switch governors from ondemand to interactive. Don't know if it's a kernel problem or a software bug. Just restart and it's gone.
[ZenFone 2 Android Development] TheSSJ:
Man I'm an idiot....the img in the zip had the wrong name...reuploaded, now it works!
[ZenFone 2 Android Development] lordpipa:
No prob man. Just letting u know.

Edit: downloaded new, all good.

Haha even I thought the same, y he is uploading img and zip, when everyone can download zip and extract img

OndemandPlus Report

Works fine while the screen is on. If the screen goes off (deep sleep), it will reboot the phone when you try to wake the phone (double tap)

So basically is not a functional governor
[ZenFone 2 Android Development] bmwkeith:
Yankactive report. When I select the yankactive governor on V29 The phone goes into bootloop upon restart until I go into recovery and wipe cache. The interactive governor does not cause this, so I will leave it on interactive for the time being.
[ZenFone 2 Android Development] mencho:
Yankactive

Almost the same issue as OndemandPlus. Though maybe was a problem with my phone. Went back to conservativeX and haven't had rebooting issues anymore.

So far in my phone I would avoid

IntelliActive, OndemandPlus and Yankactive

Best so far

ConservativeX

Good: Lionheart - Worked great but Cell Phone battery use was higher than other governors. Don't have an idea why

Good: Interactive - TheSJJ wrote that this is actually the stock ASUS governor. Is stable, but either works at full speed or in deep sleep, so there are no battery savings-
[ZenFone 2 Android Development] TheSSJ:
Yeah, IntelliActive is already removed in newest version as my phone was causing lots of troubles, too...

Oddly I don't have any problems with Yankactive (is active for about 2 hours, with frequent usage). Will check further if it remains stable...

Other than that I have succeeded in compiling zram support into the kernel, but zram is not used at all as swapon fails with "function not implemented"...unfortunately the issues present via Google showed no viable solution (config_swap is already activated, still no luck)...

[MENTION=5010777]ansebovi[/MENTION]: I fear that zram is not an option here (at least with my limited knowledge, will check for a newer source of zram and try to implement that...), didn't give up yet

[ZenFone 2 Android Development] Status_Errorv1:
currently using ConservativeX for battery life will update if any issues like random rebooting or weird system behavior... running Superzen Debloated Custom ROM.
[ZenFone 2 Android Development] ansebovi:
Aw but ok, thanks for not giving up.. .

Btw what I noticed, 4 cores gives similar, infact slightly more battery than 2 core don't know y... On demand power bias, 2 cores with every wakelock limited gives 28 mins for 10%

On demand, power bias, 4cores with every wakelock limited gives 35 mins for 10%

Usage same for both uc browsing,fb lite,amplify, settings..

And whole charge they both almost giving same 5.30sot to 5.45 SOT, only browsing, chatting... .
[ZenFone 2 Android Development] Ntrasme:
From what I have heard about governor tweaking, isn't adjusting the parameters better than enabling powersave bias? Also, it seems every other device has interactive as their best governor, but my phone only goes from deep sleep, 500, 1330, 1833. On demand (at least for me) uses more ranges like 500, 750, 1660. It has around the same battery life as interactive.
[ZenFone 2 Android Development] Status_Errorv1:
I got reboots on the Yankactive Governor
[ZenFone 2 Android Development] aziz07:
Something to keep in mind with cpus is that even when it is running at 2.33Ghz, if the cpu % load is low, it will not draw much more power.

e.g. gaming at 1.83Ghz will draw more power than browsing at 2.33Ghz. Yes, if we compare for same usage, lower clocks will use less power at the cost of performance but its not a huge difference. I personally switch between interactive for basic usage like talking/texting, music or writing and performance for pdf rendering , video editing and browsing desktop or heavy pages.
[ZenFone 2 Android Development] chobztopz:
May I know the root path of the GPU clock?

Btw, the default setting hispeed_freq of yankactive governor only 1750000, not 2333000

Very nice kernel with (what seems to be) loadable module support.

It also seems to work on custom roms (with some tweaking) for right now.....not sure if it will cause problems later but for now it works very well.
[ZenFone 2 Android Development] aaronoh:
Hey, got a stupid question for you. After flashing this is there any set-up or does it 'just work'? Looking for battery improvements so let me know if theres any tweaks I should be making, new to flashing kernels so sorry if this is considered common sense on here :)
[ZenFone 2 Android Development] ImjuzCY:
It should work just after flashing it. You may see some performance gain without configuring anything. But if you want to get further you can tweak it to suit your liking. For example of you want battery life then underclock like I do to 1250mhz max clock speed
