One quick. How much screen on time do you get on this kernel?
[Sony Xperia P, U, Sola, Go] Pandemic:
[MENTION=4378753]fleks5[/MENTION]

You can set it by your own under settings/display/screen time out !!

Kinda weird question.
[Sony Xperia P, U, Sola, Go] fleks5:
No it's not "weird" question. You didn't understand me.

How much screen on time do you get when you use the phone? Do you get 3 hours of it like on stock, or more?

I'm talking about battery consumption.
[Sony Xperia P, U, Sola, Go] monacoo:
Can you please provide flashable zip of this kernel. I can not use fastboot on my computer.
[Sony Xperia P, U, Sola, Go] Pandemic:
Oooh hahaha ok i see [MENTION=4378753]fleks5[/MENTION]

Well i guess longer :)

[MENTION=278260]monacoo[/MENTION]

Its a flashable zip, download it and you will see ;)
[Sony Xperia P, U, Sola, Go] Joker.:
but my friend pandemic ur not having that issue because ur not on enigma 6.2 rom +nemesis 6.3. Anyways now i am on nemesis 6.2 and its perfect.
[Sony Xperia P, U, Sola, Go] monacoo:
Sorry, I only read OP, did not test it. So I just flash it in recovery delete cache and dalvik cache and it is it?
[Sony Xperia P, U, Sola, Go] Pandemic:
[MENTION=278260]monacoo[/MENTION]

Just dowload the zip of 6.3 and flash the latest v6.3 with cwm no wipe from dalvik and cache needed, its already intergrated in the updater-script so it doing it automatic ;)
[Sony Xperia P, U, Sola, Go] fleks5:
Can you please put some screen shots of battery status. Thanks including display on time? Thanks!

I think I didn't see it on the thread.

Just flashing (again) this kernel 6.3, still got lag and random boot with some application, then I remove init.d folder and......no problem for now.

Will try do some test again to see how stable it.
[Sony Xperia P, U, Sola, Go] SGNote2:
Can you please add the DT2W feature to this kernel? (Double Tap To Wake)
[Sony Xperia P, U, Sola, Go] czrtst:
DT2W = :good:

Trim support would also be a nice feature :)
[Sony Xperia P, U, Sola, Go] ridsa:
I think my Xperia P run smooth and well now using this kernel (6.3) after delete init.d folder

ROM : Hanomi Moonwalker v6

CPU setting :

Max : 1,1 ghz

Min : 200 mhz

Governor : hotplugx

i/o : noop

but CPU Frequency reports still say sometimes CPU run at 1,2ghz and got battery drop likes a hell 03 hours run battery drop to 50%
[Sony Xperia P, U, Sola, Go] Alx31:
Try wheatley plus/ sio plus and use greenify...

Also try to do a battery calibration with an app and then empty battery to shut down and charge it overnight device off u should see a difference after cuple of cycles

For those with the frequency jumps I set my boot settings to the clockspeed I wanted. Then it remained at that frequency. Not sure if this will help you but it worked for me.
[Sony Xperia P, U, Sola, Go] Pandemic:
[MENTION=5464216]Hamza Murad[/MENTION]

Yeah and what you mean exactly with that ???

I tick set on boot on 1.1 ghz min 200 mhz with my white z1 settings with intergrated cpu control and cpu stats and after reboot it just stay on how it was and is !!

Dont forgot to wipe the cpu stats after reboot and you will see it then, its all good (well on mine then).
[Sony Xperia P, U, Sola, Go] monacoo:
Ok, will try. I did not change anything except kernel. I already use greenify. Last few months with Phantom at the evening I still got 20-25% (with stock and no greenify I was close to empty) but with this one my phone dies 1-2 hour before I go to sleep (and put phone on charger). I do not think there is problem with calibration, but I'll do it anyway.
[Sony Xperia P, U, Sola, Go] nicolassp:
Hi from here also,problems identified in ramdisk and not in source code so the next update will have the same build number but fixes in ramdisk.Also some scripts will be also integrated and i will tell you more when i release it.

One little question. I'm on enigma 6.1 ROM and i want to unlock bootloader in order to install this awesome kernel. Should i follow this steps in this order?

1º Unlock Bootloader (this step is mandatory to do in first place)

2º Flash kernel

3º Flash Rom

Do i have to install stock rom first and them flash kernel? In that case should i flash kernel for enigma rom or not?

Sorry but i'm a bit confused :S
[Sony Xperia P, U, Sola, Go] Alx31:
if u trying to flash enigma rom then do as mentionned in enigmas op

backup TA

unlock bl thats for sure...and then

flash stock ftf dont boot it

fasboot flash nemesis 6.2 (wait for next version instead of 6.3) with flashtool in fastboot mode or by cmd

start in recovery

flash rom's zip

enjoy aroma

let settle

reboot once again

[Sony Xperia P, U, Sola, Go] sshuter:
Thank you very much Alx31TLse :)

One last question. If i'm already on nemesis (both kernel and rom) and a new kernel is released, you advise me to follow the same procedure (without backup ta and unlock bootloader obviously) or could i just flash the new kernel in CMW?
[Sony Xperia P, U, Sola, Go] Pandemic:
Just flash the kernel with cwm again [MENTION=5349021]sshuter[/MENTION]
[Sony Xperia P, U, Sola, Go] Alx31:
flash new kernel, or by cwm, or else flashtool fastbooted wich wipe dalvik cache and cache partition needed and thats it.

TA partition back up could be done only once bro...soon as u unlocked your bootloader ur drm keys are corrupted or lost so the first backup must be somewhere on the side and don t touch it till u need warranty or bl relock ;)

just a feedback, the kernel running ok in enigma 6.2 for few hours, when suddenly my XP xperience this lag (very bad) till the point i can't wake my phone from sleep even though i plugged in my charger (I turned on the "always wake up"). after that i decided to clean cache n dalvik in cwm, but unfortunately i can't reboot into CWM. tried few times, using the "CWM", shutting down and spam vol down button when booting. even tried using flashtool to reboot into fastboot via ADB but it did nothing.

my final solution is booting my phone up while holding the vol up button (fastboot mode) and flash nemesis 6.2 using flashtool and there, it working back as it should.

if u find this post too long to read, i just want to give a suggestion to mark "Nemesis Kernel 6.2" as [Stable Version] that's all. thanks for all the time you spent for XP [MENTION=4503225]nicolassp[/MENTION] !! we all love you to the core! :good::good::good:

Great job, no problems at all on MW v7.5 :D
[Sony Xperia P, U, Sola, Go] nicolassp:
To clear some things,between the time of boot and the superuser granted access there is a time in which cpu will run on max frequency.It is absolutely normal.as for the stats showing max cpu frequencies,if you clear them after one or two minutes after boot,you will be ok.It will not consume more battery,and it will stick to the specified cpu step no matter what stats say.

I am looking to current cpu freq inside cpu control program which says current frequency: 1.2 ghz while I have set it to 1.1 ghz. this happens after hours of working and suddenly it goes to 1.2. I don't say this by watching cpu stats! :)

my main problem with 1.2 is the lags and some unstability that it is the cause. when I see lags I watch to current freq and yeah it is jumped to 1.2ghz!

not relevant.a script is causing lag.not the kernel my friend. apps request su access many times during an hour and when you allow them it simply grants permission without the annoying popup.In the time needed to grant su access cpu correctly jumps to 1,2 Ghz.I hope i am clear enough now.

Like what [MENTION=4503225]nicolassp[/MENTION] explained to you above my reply and if you feel sometime some lag then change governor and i/o scheduler to solve that little lag (just play with it), that is many times told, so i dont know why some of ya'll keep that in your mind.

Change governor like Lionheart on row

Its maybe critical for you only because i and more people dont have problems;)

This Kernel

This kernel has got usb tethering issue.Not working

EDIT

I solved this with adb drivers :)
[Sony Xperia P, U, Sola, Go] Bobo E:
I just wan to make few remarks to "1.2GHz" frequency issue. I read previous posts where you explained, that 1.2 freq is reached only for a short time when cpu-control apps are waiting for superuser privileges.

It seems completely ok, but I (and as i read the thread there are some other users with similar problems) observe diferent behavior.

At first, my phone on 1.2 becomes extremely laggy and unstable (not only with your kernel/rom, also overclocked CM got me troubles, possibly some of chips are not able to handle such overclocking). Second, once 1.2freq is hit, very often cpu settings (in Performance control, in SetCPU) got messed up. Sometimes max freq is set to 1200 (and therefore phone starts to heat up and lag even for 20sec, sometimes got rebooted), sometime min freq is set to 1000 (no lag but consumes battery fast). Only solution is launching cpu control app and and set desired freqs again.

For me, overclocking to 1200 brings more trobules than benefits. Maybe if it would not mess the cpu settings it would not hurt so bad.

Do not take this as criticism of your great work. This is just real experience of one user.
[Sony Xperia P, U, Sola, Go] Pandemic:
[MENTION=3752668]Bobo E[/MENTION]

Xperia P and the Novathor chip can easily handle 1.2 ghz that told [MENTION=4503225]nicolassp[/MENTION] also and if you phone lag then change the governor and scheduler.

But the big problem by some of ya'll is that ya'll dont read back and follow the advice what we tell to ya'll users !!
[Sony Xperia P, U, Sola, Go] Bobo E:
[MENTION=2902434]Pandemic[/MENTION]: I have read yours and nicolas's advices on past pages, none worked form me. Governor change does not work form me (i don't think that 20sec lag can be caused by governor). CPU freq settings still changing to high values (but is seems not to be kernel problem, because it appears only on Enigma, not on Moonwalker, so i am on wrong thread - thinking of deleting posts here).

Maybe not all novathor chips can handle 1200Mhz - one in my SXP definitely not. Every kernel and every ROM (stock based or CM) i had, if set to 1200MHz become extremely laggy and phone starts to heat up rapidly.
