Lol I couldn't wait for the kernel to release for the newest one so I have reverted back to 17.1.1.A.0.402 and lol today it has been released on that!

Can I flash v10 right now and flash the ftf and deselect fotakernel and kernel/boot and data? would that work? i have unlocked bl.

kernel prob

just new to sony z2 i tried to install this kernel with cwmr and it fails my phone is rooted and unlocked when installing kernel do you have to wipe anything.and does the kernel have to be zipped or unzipped any help would be greatly appreciated i came from samsung gs4

WoW ! We have Profiles for IntelliPlug now...

Balanced (4 cores)

Performance (4 cores)

Eco Performance (2 cores)

Eco Conservative (2 cores)

the "read this" was last updated on may 2013

Does this guy's definition of "Threshold value" fit?

seems like i have some stuff to test now :D lucky it's still holidays

P.S The Undervolting is fixed, it's possible to undervolt a single value now, great.

Edit: [MENTION=5125467]ron31[/MENTION]

But you do have a .314 based rom ? i flashed the .zip file via Pilz touch CWM and it worked fine.
[Xperia Z2 Original Android Development] ron31:
ya i have 314 cwm aborts the install.it gets installed as a zip right
[Xperia Z2 Original Android Development] Beetle84:
Yep, or you can unzip the zip and install boot.img via fastboot
[Xperia Z2 Original Android Development] ron31:
it still fails when i use cwmr twrp this is frustrting i can install roms and kernels to my s4 no prob
[Xperia Z2 Original Android Development] Beetle84:
Try downloading it again
[Xperia Z2 Original Android Development] ron31:
i did even put it on different sd card in recovery do you wipe anything like on gs4
[Xperia Z2 Original Android Development] Beetle84:
I dont
[Xperia Z2 Original Android Development] ron31:
i dont get it this sucks thanks for you help
[Xperia Z2 Original Android Development] Beetle84:
Have you got the latest xz dual recovery installed?
[Xperia Z2 Original Android Development] ron31:
yes i do
[Xperia Z2 Original Android Development] Beetle84:
Have you unchecked the unknown sources box in security settings for any reason?

Otherwise i have no idea.
[Xperia Z2 Original Android Development] ron31:
ok ill check thanks again
[Xperia Z2 Original Android Development] Beetle84:
It should be ticked
[Xperia Z2 Original Android Development] pdash79:
i had been holding out on 314 waiting for just this.

Awesome work man.

i am sure the entire community appreciates this as much as i do.

You rock!!!
[Xperia Z2 Original Android Development] :
No you should not wipe anything, just flash the kernel and reboot thats all! but be sure you're on 314
[Xperia Z2 Original Android Development] kumbangdesa:
My phone freeze and reboot. It keep cycling like that. Anybody face the problem?. I'm using monxdified.

Had to switch to adv stock kernel v6 for now.

Edit: success flashing with CWM. Not got any problem this time. Just the set value not sticking after reboot.
[Xperia Z2 Original Android Development] Haldi4803:
Nope, Ultimate Pure Xz2 works fine.... almost.

Using Faux123 App it does not recognize a max Clock

Anyone else with this Problem on pure stock rom ?
[Xperia Z2 Original Android Development] Jhon998:
Yes i do have it too, whenever i set the maximum freq to 2.5, after a reboot it goes back all the way to nothing, i think it because it (the kernel) automatically sits the maximum cpu freq to 2.3 maybe...
[Xperia Z2 Original Android Development] :
Works fine on EXISTENZ
[Xperia Z2 Original Android Development] :

[Xperia Z2 Original Android Development] rappa619:
Did anyone test the charge speed?
[Xperia Z2 Original Android Development] ron31:
i am on 314 itried flashing the kernel 20 time no luck
[Xperia Z2 Original Android Development] DrearierJester1:
Installed this but the cpu freq set to max to 2.45 ghz but it doesnt really put it up on that speed. Cpu kernel tweaker reads upto 2.2ghz only, any inputs or thoughts to this?
[Xperia Z2 Original Android Development] Haldi4803:
[MENTION=2784807]DooMLoRD[/MENTION]

Seems like Smartass V2 is bugged,

More tests with mp-decision can be found here

tests with intelliPlug coming soon.

Edit:

Here the tests with IntelliPlug.

i still have no idea what Hysteresis and Threshold do ^^

Sadly the "normal" Benchmark does not have enough CPU load to show how the different Presets would work :(
[Xperia Z2 Original Android Development] Haldi4803:
Okay, other question! Anyone tried Undervolting?

My Phone did NOT crash, makes me think undervolting failed.

Might be because i'm on Ultimate Pure XZ2 ROM which is said to be pre undervolted.... so does it work fine for you guys ?

Edit: Scratch that! i managed to crash it xD

After a Reboot it worked fine, there might be a Problem with IntelliPlug/some settings and undervolting.

Edit2:

AHHH got it! set max clock to 1190, set Performance governor, set CPU hotplug to UserControl and activate all 4 cores.

You can undervolt down to 600mVolt, if you set from Performance to ondemand it crashes!
[Xperia Z2 Original Android Development] Haldi4803:
3 are better than 2 posts xD

3-3.5hour charging duration from 0 to hero.

when it's empty the next time i'll flash stock kernel, but i tought that was faster....

would be glad if someone could confim these values.

edit:

Just flashed Stock 413 .ftf kernel and it does charge way faster! read here

[MENTION=2784807]DooMLoRD[/MENTION] Stock Kernel charges faster than Doomkernel v10!
[Xperia Z2 Original Android Development] rappa619:
There's something wrong with the charging still. It takes 2 minutes per %. In other words around 200 minutes for a full charge. Stock up to 90% usually goes 1% per minute.
[Xperia Z2 Original Android Development] :
Ok so here's my feedback:

Flashed v10 installed Faux123 Kernel and also Sound, in Faux123 Kernel App i've chosen the intelliactive as a governor, and intelliplug and also intellithermal or whatever that is! i've noticed some drain back there even when the phone was on idle, then i've decided at night to completely uninstall everything related to faux123 and rebooted to keep only the v10 without any app! and guess what? at night i've lost 1% from 78 to 77, with airplane mode, which is not the case when i had done some changes with faux123 Kernel App!

so in my opinion, do not play with faux123 if you don't know what you're doing, since the kernel comes already packed with everything that you'll need!

so good work and all my respect to DoomLord for this amazing work!

Cheers
[Xperia Z2 Original Android Development] nreuge:
It's weird. For my part, I've not noticed such drain, on the contrary, with intelliactive / intelliplug / intellithermal, I get very good results...
[Xperia Z2 Original Android Development] :
Well thats what i thought at first but i noticed that after uninstalling the Faux APP, now i still have 69% since the first post i posted, i did some web browsing, facebook calls and stuff! anyways i'll have to wait till it's dead and then i'll recharge my battery again and see what happens next

Oh and btw if you find it weird about my battery life, it's because i'm using an xposed module called NIpunbounce.

thanks for the reply tho
[Xperia Z2 Original Android Development] Jhon998:
Do i loose video and music unlimited when i install (flash) this kernel?

Hi [MENTION=1007992]everyone[/MENTION]

I've installed this amazing kernel v10. on my z2. I'm trying to set cpu clock to 2.4 but while the setting is available and selected the max clock speed remains 2.2. Can anyone help me?
[Xperia Z2 Original Android Development] adyscorpius:
Once you set to performance, it only stays at the highest frequency... Which is why changing to ondemand freezes it at the lower values.
[Xperia Z2 Original Android Development] MysticEnforcer:
open fauxclock,

go to fastcharge,

search 'battery throttle cpu frequency' &

set there 2457600.

activate 'set on boot',

now reboot and set cpu at max
[Xperia Z2 Original Android Development] Bazooka Tooth:
Sorry for the noob question but does this kernal throttle the cpu and gpu by default to save battery life?
[Xperia Z2 Original Android Development] Kocane:
Hey guys, what is the default hysteresis value in CPU Hotplug?
[Xperia Z2 Original Android Development] nreuge:
This default value is 8.

---------- Post added at 06:18 PM ---------- Previous post was at 06:08 PM ----------

And enable "Battery Temperature Throttling"

Yeah!! It works :D

Thanks.
[Xperia Z2 Original Android Development] nickfee:
Thanks seems working!
[Xperia Z2 Original Android Development] plasmidium:
FauxClock cant hold max. frequenz 2,458 after restart always back to 2,2 ... no tip work
[Xperia Z2 Original Android Development] MysticEnforcer:
use my tip,

it worked 100%

three people including me say "the tip works"

open fauxclock,

go to fastcharge,

enable "battery temperature throttling"

search "battery throttle cpu frequency" &

set it there up to "2457600",

activate "set on boot",

go back to cpu/hotplug,

set cpu at max &

now reboot
[Xperia Z2 Original Android Development] Haldi4803:
No, it only throttles the Speed for temperature reasons.
[Xperia Z2 Original Android Development] neo2k12:
Does anybody else experience random freezes and subsequent reboots when you unlock the screen? Happens about once every two days..
[Xperia Z2 Original Android Development] PhantomSectre:
I don't know about anyone else, but I'm getting a rather large battery drain with this kernel. Before, the battery would last at least 2 days with light use. Now, I can barely get 1 day, I have tried all the "power saving" options, but I still get a battery drain. Went back to stock last night and the drain is gone,
[Xperia Z2 Original Android Development] Bazooka Tooth:
Ah right, but does it do this with the stock kernal? I ask because I want to flash this kernal so I can overclock my phone but I don't want it to throttle down during normal use, I don't experience any overheating issues on my phone so can't see the cpu/gpu throttling helping me at all. Is the chip on these phones like the turbo boost on laptop cpus where it only kicks to its maximum clocks under load?
[Xperia Z2 Original Android Development] nosidefcp:
is there anyway to flash the kernel in a z2 with unlock bootloader allowed:no, with root and existenz rom?thanks
[Xperia Z2 Original Android Development] waynekirby:
Nope, only stock kernels can be used.
[Xperia Z2 Original Android Development] Haldi4803:
This is somewhat offtopic but okay...

Yes, Stock Kernel and Doomkernel do automatically underclock when the phone gets to Hot, Doomkernel has IntelliThermal settings which you can configure when you want it to throttle, so you can grill eggs on your phone!

The Phone does NOT always stay on maximum clock. The Governor set CPU clock to what it needs to be, when you browse the web and don't need much CPU power it will clock down from 2246mhz to 300mhz, when you touch the screen it instantly ramps up to 1190mhz. when you scroll the page it automaticaly decides if it needs more or less cpu power and switches clock.

Idle WiFi DeepSleep works kinda fine if you ask me!
[Xperia Z2 Original Android Development] PhantomSectre:
By the way, I'm using MIUI. The power drain happens when I flash v10 kernel and the phone constantly runs hot. Maybe something is not compatible?
[Xperia Z2 Original Android Development] Bazooka Tooth:
Ah ok that makes sense, so left to default the cpu/gpu on this kernal and the stock one should perform exactly the same, it's just this one you can manually control everything right?
[Xperia Z2 Original Android Development] drknezz:
Read the OP mate, only compatible with stock KK firmware.
[Xperia Z2 Original Android Development] feis:
But miui is based on romaur, which is based on stock firmware
[Xperia Z2 Original Android Development] PhantomSectre:
The ported MIUI for the Z2 is the latest stock KK firmware, otherwise DK would cause a bootloop. It's basically just themed to look like MIUI with a few MIUI apps thrown in.
[Xperia Z2 Original Android Development] DooMLoRD:
yup [MENTION=3332811]faux123[/MENTION] is working on it...

try FauxClock app

It all depends on your configuration... start tinkering with things one at a time and find a sweet-spot for this...

only stock ROMs are supported as these are VERY well tested by Sony... with customized ROMs I cannot guarantee how it will work...

[MENTION=4924807]MysticEnforcer[/MENTION]

thanks for tip for battery settings!

@ slow battery charging issue

I will investigate whats going on

[Xperia Z2 Original Android Development] Silvio Scarani:

[Xperia Z2 Original Android Development] nreuge:

Existenz v2.0 is a custom stock based rom .314
[Xperia Z2 Original Android Development] Chillzone:
I also have the battery drain. I'll come back with some number and benches. I have lost over 3 hours of screen, with this on powersave features. Less lag and more SOT with stock kernel. :/
[Xperia Z2 Original Android Development] xnknown:
Seems like doomkernal has higher battery drain then stock, anyone find that to be the case?
[Xperia Z2 Original Android Development] Destroyedbeauty:
[MENTION=535343]all[/MENTION] Try with tuning your respective CPU Governor / IO Scheduler / GPU governor before complain about battery drain..

Why wouldn't he make a kernel for us after community paid for a device for us
[Xperia Z2 Original Android Development] sefadrin:
Hi mate.I'm use Existenz v2.0 rom and with unlock bootloader.But a several times when I flashed Doomkernel V10 , my device still on bootloop.

Can you help me?(Note:After unlocking device I'm restoring TA-is it harmful? )
[Xperia Z2 Original Android Development] The Peterle:
Seems like a broken downloaded zip or a recovery fail? Try again.
[Xperia Z2 Original Android Development] Jhon998:
Restoring TA will lock the bootloader
[Xperia Z2 Original Android Development] nreuge:
It is obvious that DooMLord and Faux are working together to make this kernel, so what do you want more ?
[Xperia Z2 Original Android Development] waynekirby:
Fauxkernel.
[Xperia Z2 Original Android Development] Jackos:
I agree. Even if the devs work together it would be nice to see two independent projects, especially for the Z2.
[Xperia Z2 Original Android Development] nreuge:
And Faux will use his own patch, those that he send regularly to DooMLord. And finally you will have 2 identical kernels ! It's useless. On the contrary, I think the conjunction of efforts of these two great devs is the best thing that could happen.

And with DooMkernel + Fauxclock, you can set so many many different combinations of options... Work yourself on the settings and you will have the kernel of your dreams !
[Xperia Z2 Original Android Development] Jackos:
I disagree with that. Let me compare this to Faux and Yanks kernel. There both quite similar, yet so much different kernels both having their advantages and disadvantages. Also DooM is quite busy these days, so we could get a Faux kernel earlier and vice versa when Faux is busy.

Also it would bring some competition to the Z2 forums. Monopol is always bad for innovations.
[Xperia Z2 Original Android Development] sefadrin:
Thanks my friend,you are right.Today I downloaded Doomkernel V10 again and flash to device and result;successful.I think I first downloaded zip file was faulty.Thanks again. :o
[Xperia Z2 Original Android Development] festa20:
We would have two separate kernels if they both make one.

Which will be better plus when doom stops doing kernels at least we will have faux kernel.

Its good that we have patches from him and what not but the fact is community paid for him a device why wouldn't you want the kernel from him with his own stuff in instead of in dooms kernel.

Either way its not going to happen but would be nice of a new kernel and extra development for our z2's

intelliactive and stamina mode

Im using this kernel with intelliactive governor, max freq 2.266, min 300 with stamina mode turned on. But when i touch the screen, the freq goes to 2.266.. Is this normal? I thought stamina mode underclocks the max freq? Sorry for the noob question
[Xperia Z2 Original Android Development] Jhon998:
How can i upgrade the twrp recovery to 2.8.0.1???????
[Xperia Z2 Original Android Development] The Peterle:
Changing recovery is not possible on doom kernel.

Unfortunately. ?
[Xperia Z2 Original Android Development] Haldi4803:
No! Stamina Mode is an implementation from Sony and limits ALL mobile/Wifi Data when the screen is offline !
[Xperia Z2 Original Android Development] Kocane:
I guess he's talking about the "extended usage" thingie. Whether or not the 'touch boost' of a governor should have a lowered clock with this enabled or not.
[Xperia Z2 Original Android Development] azreen91:
My bad, yes i meant the extended usage which restricts the hardware.. I thought so that this might be due to the touch boost.. So Is this normal?

One more thing, If i set max freq to 1.7, should the touch boost lets the freq jump to more than 1.7?
[Xperia Z2 Original Android Development] Jhon998:
Impossible.
[Xperia Z2 Original Android Development] Haldi4803:
is it on purpose that 587mhz is stock GPU clock? Or is it the missing 500mhz that makes it jump to 587mhz?

At least I do have 587mhz max clock shown by GPU small app after a fresh reboot and I cannot select 500mhz via Faux App.

Edit: my fault -.-

587 is stock.

500 was special underclocked frequency.
[Xperia Z2 Original Android Development] Perfectdevil:
It will be great if you added DANCEDANCE governor and update TWRP to 2.8.0.1 on your next release!!!!
[Xperia Z2 Original Android Development] RISHI RAJ:
Hello guys Im not new to doom kernel, unlocking bootloader or drm keys but want to be sure that if drm keys are not there will sony features like update,bionz work.I just bought a z2 & read somewhere that unlocking will not restrict me from any sony related features like earlier devices
[Xperia Z2 Original Android Development] Envious_Data:
I havent lost anything from unlocking bootloader

Using branded firmwares stops things from working on a unlocked bootloader
[Xperia Z2 Original Android Development] Jhon998:
X-reality engine, and video unlimited and music unlimited is gone after bootloader unlocking, but ALSO make a TA backup before unlocking bootloader to be able to relock it again.

Lower your CPU clock to stock values.
[Xperia Z2 Original Android Development] Kocane:
It isn't on stock values? Hm, that wasn't on purpose.... what are the stock values?
[Xperia Z2 Original Android Development] Jackos:
I guessed you overclocked your CPU, because that's what the logcat says.

The default value for the CPU is 2265600 (2265Mhz).
[Xperia Z2 Original Android Development] Kocane:
Yeah my max value is indeed 2,266 ghz.

How about the massive amount of "IRQ40 no longer affine to CPU1" spam in the log along with "PM: Device alarm failed to suspend"

Might be an intelliplug thing but I've no idea... I wish DooMlord had more time these days :P
