Hi,

I'm currently using stock 4.1.2 XELL4 version of android. Can I savely flash this kernel via odin? Or do I need to upgrade my rom to XELLA first in order to have the same version in rom and kernel? Btw. I'm going to install Philz recovery aswell first in order to do a nandroid backup.

So is it required in general to have XELLA first? Or is it simply the kernel which comes with XELLA (I'm not quite sure there if I correctly understood this)

Thanks very much for your answers!

And just for bragging ,battery an performance screenshot too of recent self experiment of a real time scenario I did with the taught of squeezing the battery life any way possible to get me threw the day. :)

Edit: sry about the double post peeps. Couldent edit it into the already posted one above :p
[Galaxy S III Original Android Development] mamba720027:
Its ok to install it over the xell4. Doesn't need to have xella rom in order to use the kernel.

The kernel will still have the fix to protect your device from the bug if that's what you're worry about.
[Galaxy S III Original Android Development] xukaisheng:
Mind sharing your settings?
[Galaxy S III Original Android Development] userguy:
Thanks, thats exactly the answer I was looking for!

Do you suggest factory reset after flash? Resp. wipe cache/ dalvik is strongly recommended I guess?

Cheerz
[Galaxy S III Original Android Development] danarama:
Never hurts to wipe dalvik but its not a requirement.
[Galaxy S III Original Android Development] mamba720027:
Sure,but its a lot of fine tweaks so screenshot instead of type which seems more clutter than anything.

Edit: page 337 have a more brief explanation about what I was doing to arrive at what u see in previous page.
[Galaxy S III Original Android Development] The Broken:
You should consider changing the min GPU mhz to 54, because when you are not touching the screen (reading on internet or apps that aren't games) The GPU has no load, therefore 54 mhz would be better for your battery ;). You can check it with the floating GPU monitor.
[Galaxy S III Original Android Development] funeralcrows:
Is LED fading option planned. And maybe the screen timeout delay option that assists the CRT off animation?

I'm loving the kernel despite. Just asking :)
[Galaxy S III Original Android Development] mamba720027:
Thanx for the tip but I get random reboots or lags with below 108mhz and I can't UV those 2 lower than it is already. Not worth it since the volt is not much difference than 160mhz for the trade off of performance. But I agree with u,just too bad my phone can't handle it. I bet more peeps may have it work on their device like yours. :)

Have no idea but on omega rom you can use the romtool app to download crtoff animation and works. Also I'm not 100% but I think that app on Google play "light flow" have led fadeing option. Can always check.
[Galaxy S III Original Android Development] andreasy:
I'm wondering if somebody could explain this question to me: I have been using Perseus instead of stock kernel since I got my phone but I always had this concern. When Samsung releases a new ROM and together they release new Kernel as well, doesn't mean that this kernel is more up to date, with more improvements and newer staff? for example noe the latest kernel is ELLC, but on the other hand custom kernels like Perseus remain the same. So according to my thought, don't we miss anything signifigant by skipping the newer stock kernel and installing the custom one?
[Galaxy S III Original Android Development] danarama:
Most likely there will be no changes between all the official 4.1.2 kernels.. they'll all be update 7 source, which has already been released to the public.

XXELKC to XXELLC all look the same to me
[Galaxy S III Original Android Development] carbonize:
So the bit in the opening post about the dev using the patches from Samsung's latest kernel doesn't give a clue to the fact that custom kernels are always updated with any new tweaks and patches Samsung release?
[Galaxy S III Original Android Development] AndreiLux:
Wat.

Custom kernels are not always updated with new patches, other kernels use Samsung's source dumps and base their kernels on that. I haven't used a base like that since Update 5 a few months ago and have switched over to commit patching. See the repository for yourself and compare it to other kernels.
[Galaxy S III Original Android Development] danarama:
Plus blindly switching base will likely bring undesirable features too.

Custom kernels are the best of both worlds. For me, I root specifically to get a custom kernel.
[Galaxy S III Original Android Development] borich:

[Galaxy S III Original Android Development] dimi22:
Hey guys,

I am using the XELLA stock rom ATM. No root..

Is it possible to just flash this kernel with odin. under pda if i am right?

I would also like to know if there are any internet tweaks in this kernel? and if there no tweaks,, can you recommend or discommend try the internet speed tweaks from the pimp my rom app.

thanks
[Galaxy S III Original Android Development] MuertoKo:
Just flash it :) and guess you need Root for the tweaks as it comes with Stweaks installed, just not sire about the need to root for that

I have come across the Stweak Profile app which works with perseus kernel http://xdaforums.com/showthread.php?p=35149008. Any chance you could provide a backup of your settings, it'd be a lot easier for others to use and for yourself.

Plus it'd be useful to share other users settings.

[Galaxy S III Original Android Development] darkbahamut:
I've just recently switch to Perseus (from Siyah) a few days ago, which and almost everything seems great I see to be struggling with the GPU settings somewhat. Settings I've run for months unchanged are highly unstable under Persues.

It almost looks like the voltage increase associated with moving to a higher frequency step comes in too slow/late. If you can get it to run, then stress tests/games/benchmark will all complete with no artifacts or graphic problems as long as it will survive the first 1-2 seconds. Often however, the phone will hard lock right aware as the clock speed ramps up, yet the voltage increase seems delayed. Given that tests all run fine if the tests manages to start shows the voltage level applied at any given speed step (I've tested all of them) is stable, just that for some reason it can manage to change speeds in a stable manor. I understand the scaling logic is Perseus is different and new, but I just wondered if this was intended behavior or a side effect of that change?
[Galaxy S III Original Android Development] dimi22:
is there a way to root XELLA maybe without changing stock kernel that would be the best for me

[Galaxy S III Original Android Development] tontiv:
how do you manually change values in stweaks? kinda difficult to dial down by just a couple of units with that slider
[Galaxy S III Original Android Development] mamba720027:
If you mean the CPU then just think of it like this for example - 900 -875 -850 -825 -800 etc . Then u can adjust it in between the above example values to a slight more volts if necessary.

Don't focus on the "000" if it confuse u. The rest settings is pretty self explain.
[Galaxy S III Original Android Development] GrimPivo:
I think he mean that it's slightly difficult to change the values with sliders.

Am I right?
[Galaxy S III Original Android Development] tontiv:
you got it :) so how do you guys go about it?
[Galaxy S III Original Android Development] mamba720027:
simply just use the slider to either slide left or right to increase or decrease the values. Should be simple enough :)

And some use scripts instead.
[Galaxy S III Original Android Development] funeralcrows:
Staying on Siyah for the LED fading & FB Early Suspend Delay but secretly in love with Perseus... <3
[Galaxy S III Original Android Development] Anakha56:
I make sure the slider is selected and when it moves I slowly move my finger down and across so I can read the values while changing the slider. Having big fingers is no fun but you get used to it after awhile :p. One thing to be wary of (probably just me but hey) your slider wont return to default voltage levels for the GPU it will either be under or above but you will never be able to slide back t default values for some reason...
[Galaxy S III Original Android Development] vadonka:
Siyah doesn't have the SDS fix, but perseus have it. I strongly recommended to use perseus until Siyah implement the fix. Or if you have a little programming experience you can always cherry pick the Siyah kernel missing features to the perseus and rebuild by yourself, like i did.

[Galaxy S III Original Android Development] _andrea_:
Hi guys, don't know if anyone reported this yet. I'm using Perseus since rooting (i think alpha 25) and all is running great: top performances and good battery life. The only thing to report: sometimes when i recieve multiple whatsapp messages in a short period the vibration motor works in the first messages but on the second it produces a weak vibration (or semi vibration). The same thing for the audio of the notification: sometimes it riproduces only a part of the sound notification sound (often when it does the weak vibration thing). Someone has the same problem?

I think this is kernel related (at least on my device) because i've tried multiple roms in this months (ARHD, Wanam, Insertcoin) and my phone does this only on this custom kernel (i use only this or stock kernel, don't know the others..). Another information: s-tweaks on default settings, phone is in standby when receives messages (screen off)
[Galaxy S III Original Android Development] adamski123:
Its the effect when u turn off ur phone that makes it look like a tv is turning off
[Galaxy S III Original Android Development] 0asis:
Seems legit to me as the messages or notifications are displayed faster than the time it takes to vibrate or ring

To me it's a normal behaviour and nothing related to kernel

[Galaxy S III Original Android Development] inscythe:
I found the same issue with Perseus. I thought it was just my phone, but yours confirms my situation as well. I have the same weak 2nd vibration issue, which does not show up in stock kernel and Siyah kernel; definitely kernel-related (I just switched back to Siyah for some testing). I found that the weakened vibration only shows up when the vibration is long; shorter vibrations don't have the issue.
[Galaxy S III Original Android Development] zuluman:
i instaled omega v37 with perseus kernel but

rom has twice busybox,in sbin/busybox comes from kernel and system/bin/busybox comes from rom

for that (i think) when type sh in terminal emulator shows that "sh precmd not found"

scripts dont work in init.d folder

but when change kernel another one i have not the problem.
[Galaxy S III Original Android Development] dezeubby:
Thank you for this excellent kernel ... i think is more better than boeffla or siyah .

Small question: How can i do a clean install of this kernel ? Just flash or i need to delete a folder or something ?

I'm running this with Ripper ROM on an i9305, and can't get my CPU to go over 1000MHz (running stability test app from the market). Any ideas? I've tried lowering the up threshold a bit.

Power Saving is off, and I'm only using stweaks to set frequencies etc

I even tried setting 1200 min and 1400 max last night, and it still reported as staying on 1000 when I ran stability test

wich is the best ROM for this kernel ??

all i want is battery life and to be really really fast without any type of contact lag, phone lag etc etc.??

So do I!! I was thinking that maybe i had some hw revision that works in different way. Glad to know that!! Well let's wait for Andrei's answer!

cm10: super fast but eat the battery hell fast no matter what custom kernel you used

stock or any stock based rom: may a bit slower than any cm based rom but fast enough, with Siyah or Perseus the battery life way more better

im tried every combination, i found for myself the best is the omega rom+perseus/siyah kernel

its have a good balance between speed and battery life

And if you actually visit that link you posted you will see that I'm sending people back here in this thread for posting issues; It's the correct thread.

Please refrain from such idiotic posts in this thread. You are not contributing with anything. Keep the stupidity in the general forum.

They did fail, and the failure rate increased with time. The problem supposedly lies in the internal memory wear leveling algorithm. Failure would only happen after repeated memory cell rewrites, and that takes time. Over the last month or two, reported failures have increased by a lot. It just means that the NAND chip is reaching its limits while in the first few months it was still fresh.
[Galaxy S III Original Android Development] mamba720027:
Try restart and go into cwm, fix permissions and then see if its fix.

If not then delete STweaks using a file manager at system/data. Reboot. Install the one from marketplace and wouldent hurt to restart again and fix permissions.

Also make sure you have SU and its updated.

Edit:also if nothing works,try "setcpu" app to verify if frequencys change.

Hi all,

Couple of things really.

Trying to get the most out of this kernel but i keep running into performance issues especially whilst gaming, the UI is spot on, no complaints there.

I've just performed a fresh install of my rom, your kernel and the ext2internal mod rebooted.

So everything is back to basics.

I'm just looking for a performance boost over whats available from this stage.

Can anyone help me out with this.

My apologies if this isn't the relevant place to ask this.

Also with the ext2internal mod, i'm seeing 2 x 59GB memory reports from storage, i know that this kernel has support for init'd so wondered if anyone knew about that too.

Many thanks. :)
[Galaxy S III Original Android Development] nfsmw_gr:
If you seek more performance try overclocking the cpu and lowering up threshold to around 75% and decrease a lil bit the hotplug runques(by 25 or 30) and/or frequency (by 100mhz or so).

Also about init.d try with script manager to check this script to be run as root and on boot.

Finally try lowering gpu threshold(about 10%) and overclocking it too(by the next available frequency).

Of course the battery drain will be higher,but if you seek performance try it. :)

Btw there's an in depth guide in general sub-forum on how to overclock this device.
[Galaxy S III Original Android Development] dlads:
Cheers m8, i appreciate it. :) I'm ok with overclocking, but i normally tend to grab a kernel that performs well from the off. I've heard great things about this kernel and always wanted to give it a whirl, but i've always shyed away from tweaking voltages and such at least on my phone anyway, primarily because i don't fully understand what everything does, i can hazard an educated guess but i'd rather not tamper with it without being 100%.

Thanks again, i'll try your suggestions.
[Galaxy S III Original Android Development] jakmeister:
@Andrei:

From another Thread:

"...To my kernel the tweaks are condensed to this:

Quote:

echo "60" > /sys/devices/system/cpu/cpufreq/pegasusq/up_threshold

echo "20000" > /sys/devices/system/cpu/cpufreq/pegasusq/sampling_rate

echo "10" > /sys/devices/system/cpu/cpufreq/pegasusq/sampling_down_factor

echo "30" > /sys/devices/system/cpu/cpufreq/pegasusq/down_differential

So people can just adjust in STweaks their settings manually, or, if they are especially lazy, here's a flashable zip attached to insert the new values into your profile for my kernel.... "

I entered these values manually in STweak (I'm running ARHD V18 with Perseus 31.2), but it caused the CPU to continue running at full speed (1.4GHz) and burnt through my battery. Did I do something wrong? :confused:
