It is the best kernel I ever had on my phone by now. I hope that the new code, released a few days ago, to bring opportunities to make our phones even better. Thanks Stefan Gündhör
[LG Optimus 2x] Stefan Gündhör:
Changelog:

March 02, 2012 -- version with strong vibration added - thx to spica1234!!
[LG Optimus 2x] Stefan Gündhör:
Attention: there was a problem with strong vibration version, so temporarily removed! will come soon again
[LG Optimus 2x] Stefan Gündhör:
As the version with strong vibration isn't ready yet due to problems, I have some other goodie for you:

Changelog:

March 02, 2012 -- Additional version without OC/UV possibility @1.0 GHz Stock-max.Speed -- for stock kernel lovers ;-)

Max ScreenOn speed 1.0 GHz, max. ScreenOff freq. is still lowered though!
[LG Optimus 2x] Stefan Gündhör:
Changelog:

March 02, 2012 -- Additional experimental (big question battery) versions with permanently active 2nd CPU core

new known bug:

kernel will sometimes temporarily revert overclocking speed to default 912 MHz of OC kernel -- only the OC versions of the kernel are affected.

this can be annoying but doesn't affect stability. I will try to solve this bug with v1.2.1
[LG Optimus 2x] feav:
Yes, I like it! Thank you much!
[LG Optimus 2x] Stefan Gündhör:
Fine :) There is also a permanent 2nd core version without OC :)
[LG Optimus 2x] Remington78:
Hi does this support voodoo sound??
[LG Optimus 2x] Stefan Gündhör:
sure :) all versions do
[LG Optimus 2x] Stefan Gündhör:
okay I nearly found the reason for the OC bug:

once you OC'd cpu will run at correct oc speed. as soon as screen has been turned off and turned on again, cpu speed / overclocking will be reset and OC kernel default speed of 912 MHz will be used. this is the reason for the low antutu benchmarks some of you experience.

I'm sure I will find a way to solve this. Bug is located in kernel file

drivers/cpufreq/cpufreq.c

I think.

However suggestions are welcome too but I guess I will have to solve it myself :)
[LG Optimus 2x] vpaulve:
I dont understand, I just wiped dalvik cache, then? where can i "reset" it? only reboot option, which option? any combination key? Will i lost root?

Ohh, i think that you say about: wipe data/factory reset. Uhm..
[LG Optimus 2x] Scougar:
Ok.. I have gone into CWM...

1) Make sure your battery is charged (For safety).

2) Make a BACKUP

3) Wipe dalvik cache

4) * Wipe data/factory reset (just to be on the safe side), you have the backup anyway!! :-)

5) Select the ZIP file ROM to flash and flash it.

Once you have done it.. reboot the phone. It may take a fair few minutes to reboot as it has to do the initial setup. Be patient :-)

NOTE: * You don't necessarily have to do step 4, but I'd advise it :-)
[LG Optimus 2x] Stefan Gündhör:
I'd rather wait for the new version of the kernel with fixed OC code! you can find the reason 2 posts above
[LG Optimus 2x] vpaulve:
I do it always when a install a new rom. Wipe cache too.

Thanks!!
[LG Optimus 2x] Stefan Gündhör:
Changelog:

March 03, 2012 -- guestekrnL v1.2.1:

Overclocking bug fixed - once CPU is OC'd it will stay OC'd now

changes in cpu speed steps: new steps are 216, 324, 503, 800, 1015, 1100, 1216, 1408 (same steps as etana kernel currently uses)

kernel default cpu speed now 1.0 GHz like stock kernel

screen off max cpu speed now 503 MHz

changes again in second core handling

stability fixes

strong vibration editions (thx to spica1234) -- please note that strong vibration might cause problems if haptic feedback is enabled in LG stock keyboard:
[LG Optimus 2x] Lo_RaT_PeNaT:
stefan, I've been testing its latest version since launch, and it really works well, does well, is soft, really a great job, congratulations. Soon abandons this forum, and if I forget, I take this post to thank you and many other developers the moments of entertainment that you have posed. A greeting and thank you very much.
[LG Optimus 2x] vpaulve:
With guestekrnl v 1.2.1

Antutu 1408 MHz

1) 6752

2) 6717

3) 6664

Excellent!

After I was testing 4) but my cellphone reboot because battery drain totally into testing Antutu (I started with battery 40%) . Then:

1) 5266

2) 5402

I'll reboot again.

[LG Optimus 2x] Stefan Gündhör:
don't take benchmarks too serious :-)

for me values are decreasing too after longer use of the phone. maybe it's some memory-/ROM-related stuff and not (only) kernel.

but I will try one more thing for planned v1.2.2, maybe it will help a bit.

Currently I am testing the noOC (non overclockable) version of 1.2.1, and I can only recommend it, it's very smooth and depending on the sqlite libs you use, you should get up to about 5840 points or more in Antutu. This is far better than unchanged stock kernel.

I will check after some hours again if the results also decrease in noOC version.
[LG Optimus 2x] Jimboi2008:
Awesome kernel Thank you Stefan,

i had zram activated but i dont see any diff. on perf. maybe its just me wierd
[LG Optimus 2x] wapz:
Hi Stefan, tonyp got ICS running on the old bootloader, flashable from old cwm, and needs some kernel help :)
[LG Optimus 2x] stevvie:
Thanks Carburano, Stefan and Trym
[LG Optimus 2x] Stefan Gündhör:
How the hell did you get 5 days of uptime on battery??? :D:D:D
[LG Optimus 2x] SREEPRAJAY:
Stefan,

I am not surprised as I had consistently for three times a battery performance of more than 4 days + with device idle condition.....

So, this is a good device with no work....lol

But, I can say this device is good.....no matter if we are on ICS or not. :)
[LG Optimus 2x] Stefan Gündhör:
So you are saying the device itself is good and responsible for the good battery, not the current ROMs and kernels? :D :p
[LG Optimus 2x] SREEPRAJAY:
no way...I have seen the pure stock.....I know each of you guys are weaving MAGIC always and making this device extra-ordinary....

not even in my dreams will I take the credit off from such friendly, knoweldgeable and dedicated developers....I had previously used a few WM devices for a long time and it lacked such support and guidance.

I would always remain grateful to all you nice and friendly people, who are using their time to support such community which even its creators have forgotten.
[LG Optimus 2x] vkk178:
I had a 1% drop over night ~8 hours with no data connection . but then as I checked email and xda for 15 mins it dropped 10 - 15 % :silly: .. This was on the hybrid ROM though . Yes the 1% drop was not possible on stock I have to admit
[LG Optimus 2x] Ferrum Master:
It sounds more that your battery is a goner to me.
[LG Optimus 2x] SREEPRAJAY:
just a small point to make here....

I was on DM 1.6/1.2.1/1.3 with Supersonic as well as gueste Kernels. Previously I have seen 1%drop in Topo's, Civato's as well as Navlem's....so not the first for me
[LG Optimus 2x] Stefan Gündhör:
:D

was kidding anyway!

Today I can proudly confirm that there is no more memory leak in latest guestekrnL. Now matter how long I use it with my GoodBye ROM, my phone always stays as smooth as after a fresh boot. Who has made similar experiences?
[LG Optimus 2x] SREEPRAJAY:
I agree with you....but may be it is my experience....or my opinion as a noob....whatever ROM/Kernel, there is always a drop in the RAM available.onlly difference is, if the how much the drop is, if it affects the performance in such a way that it is beyond normal use.

the WM devices were that way a bit different, HTC was always steady and then Acer devices were a bit sluggish when you multi task and then it would be normal once you are back.the ANDROID does not behave this way...

Maybe its my noob feeling....but yes, Gueste Kernel controls memory leak well....but frankly,

mate....me being in avaition, I always believe that the best is still to come....complete leak stop is something I am looking for...I am sure you, Spica, Vadonka or such brilliant Kernel Developers will get it soon.

Thanks for what you have done
[LG Optimus 2x] jimguitar:
Stefan i can confirm that memory leak has been disappeared.

But among all the kernel versions of yours the winner is by far the guestekrnl v2 symbiosis chain.

Versions v2.1 are more smoothness, but i had some problems with the memory management.
[LG Optimus 2x] Stefan Gündhör:
Thanks,

could you please specify these problems you had with memory management?
[LG Optimus 2x] kfallz:
One problem with any change to vibration driver/strength etc seems to be that the vibration is extremely uneven. For example when I'm typing an sms, the strength and timing of the vibration is all over the place with haptic feedback enabled, same thing in spicas kernels.
[LG Optimus 2x] Stefan Gündhör:
I don't understand what

means :confused:

What's wrong about the timing?

Concerning vibration strength:

- on stock there are 2 output devices for vibration, one outputs very low vibration the other one strong vibration.

- both output devices can be further tweaked by the voltage assigned to them, low voltage means lower vibration and high voltage higher vibration

- kernel DEV has to choose one of the two output devices

- original stock output device is the weak one

- if you use the vibration intensity levels of guestekrnL for the weak output device, you would get as maximum vibration strength the strength that is currently default strength in guestekrnL v2, which in fact is intensity level 1800 from 3700 in current kernel

- this is why I decided to use the strong output device and lower voltage per default instead of using weak output device and maximum voltage per default

- advantage: with strong output device you can achieve the same weakness as weak output device, if you just take minimum voltage / intensity level, AND additionally you can achieve much stronger maximum vibration intensitiy than you could ever achieve with weak output device using the same voltage/intensity levels.
[LG Optimus 2x] kfallz:
While typing fast, the strength is mostly "right", but now and then it jumps way up and becomes extremely strong. Almost like it's stacking the vibrations for additional keypresses, and then releasing them all at once, but it doesn't do this on default driver, there it's just as it should be, separated short vibration bursts.

And the timing, well i guess that was a bad description, what i wrote here is probably a more accurate one.
[LG Optimus 2x] Stefan Gündhör:
Okay I think I can understand what you mean!

There are now own vibration drivers, like mentioned by some people, there is only the original stock driver where the output device for vibration has been changed to a stronger one and additionally in guestekrnL the ability to change the intensity has been added.

BUT I can compile you a kernel version of v2.1 with lower vibration output device, the one also used in original stock kernel!

Just wait half an our, I'll make that one for you :)
[LG Optimus 2x] kfallz:
Nice, thx ^^ And if i can have my pick, I'd like it to be the hoc symbiosis 2.1 version xD

Should of course also mention that the kernel otherwise seems to be a nice upgrade from 1.8.1, also loving the integration of under/overvolting in gueste oc.. could never understand why trym removed myrtundervolt Oo Afaik there was no other app as simple as that that didn't include a bunch of other unecessary stuff.. had to spend a while to find a dl link that worked lol.
[LG Optimus 2x] Stefan Gündhör:
Changelog already available: https://github.com/StefanGuendhoer/...mmit/c15892106a0300551d0e23a6430a11d044bdf0f9

ALL versions are already compiling, also aroma version - I will just add a hint in the filename that these versions use the low vibration output device instead of the strong one. Vibration intensity can still be changed, you just won't be able to get it as strong as with the strong output device.

Upload soon :cowboy:
[LG Optimus 2x] kfallz:
Oh ok, sweet!
[LG Optimus 2x] jimguitar:
Stefan,

On symbiosis v2.1 with medium use of browser,hard use of camera the phone became a" little bit " laggy in a couple of days.

I mean that apps like contacts,camera, application manager, are launched with some delay instead of version v2 symbiosis that they are launched immediately like they are already loaded in memory.

As i have mentioned in a previous post, with symbiosis v2, so far i haven't manage to make the phone laggy!!

Thanks
[LG Optimus 2x] Stefan Gündhör:
The editions with standard vibrator output device have been added! They have "vibrator 2" in their filenames! The standard vibrator device is weaker but maybe more precise than the stronger one. Vibration intensity can be changed as well in these editions.
[LG Optimus 2x] kfallz:
Now It's perfect ^^ @vibrator2
[LG Optimus 2x] TrymHansen:
Absolutely loving the vibration in 2.1 Stefan, one of the main reasons I preferred stock was the firm feel of the vibrations.ln CMx vibes always felt... what's a good word ... flabby.

Though I don't need it myself (after you made stock ramhack) I'm sure some would appreciate a symbi0sis with the firmer vibes as well.
[LG Optimus 2x] flat__line:
Spica and back ...

I would like to give latest spica's kernel a try: if I want to come back to gueste afterwards, are there any scripts I should manually remove to ensure there are no detrimental left overs?

Thanx,
[LG Optimus 2x] TrymHansen:
The guestekrnL installer will try to tidy up the init.d directory, but if new versions of other kernels introduce new scripts the guestekrnL-installer does not know about there may be some leftovers.

So to make sure you can simply open the guestekrnL-installer on your PC (or phone for that matter), see which scripts are included, and remove other scripts from the phone.
[LG Optimus 2x] Stefan Gündhör:
Release guestekrnL v2.2

guestekrnL kernel v2.2 + GuesteOC v2.3 (TrymHansen) -- with Aroma :cool:
​

Changelog latest version:

v2.2

smoothness-related changes for higher smoothness

better RAM management

tun.ko now as kernel module instead of built-in in kernel

dropped symbi0sis-toolchain edition, instead added spica1234 toolchain edition (like the name says this toolchain has been built by spica1234, credits for this chain go to him)

new unique feature: introducing dual-vibrator support:

in GuesteOC you can set the kernel's vibration intensity (like you already know)

new: intensity 1500 - 2700 uses "weak" vibrator output device for vibration (the one used in original stock kernel)

intensity levels >2700 - 3700 use the "strong" vibrator output device

some prefer the weak device because it seems to be more "accurate", others prefer the stronger one

now it's completely up to you which one to use, without having to change the kernel version! Enjoy :cool:

My phone won't boot after flashing 2.2 I'm stuck at the LG logo. I'm coming from a fresh 1.7 DM with 2.1 gueste kernel (after full wipe).
[LG Optimus 2x] Stefan Gündhör:
Sometimes Aroma installer causes this - it isn't permanent. Take out battery, put it back in, boot. It will work then.

If it for any reason still doesn't boot, reflash the kernel, then it will for sure.
[LG Optimus 2x] Aiden88:

[LG Optimus 2x] Norlam:
Reflashing worked. Thx a lot :good:
[LG Optimus 2x] jmsmartins:
I would say anyone without overclock :)
[LG Optimus 2x] Stefan Gündhör:
The recommended version is the pre-selected one in Aroma installer. It is built with flix123's toolchain which provides the smoothest scrolling of all (in my opinion) and battery is good as well.

guestekrnl-chain-edition has good battery as well. spica1234-chain edition I don't know (because it's new). but for HP kernel it's said to be stable, low power consuming and also smooth. Though I think flix chain is smoother but try yourself.

FlixEdition Community release is basically the same as the preselected kernel but with a different name and different default GuesteOC settings. This edition will consume more power for providing even more smoothness.

I can't deactivate Zram. When I click on deactivate it just keep saying "please wait" but nothing happens.
[LG Optimus 2x] Stefan Gündhör:
Just tried - works fine for me. Looks like missing superuser rights. Did you grant GuesteOC superuser rights? If it didn't ask you, open superuser app, remove GuesteOC from the list, re-enter GuesteOC and try again. Maybe just slide swappiness slider a bit then it should ask you for Superuser permissions.
[LG Optimus 2x] Norlam:
I granted GuesteOC superuser rights when I activated Zram.

Edit: I reentered GuesteOC in superuser but it still doesn't work.
[LG Optimus 2x] Stefan Gündhör:

Thanks
[LG Optimus 2x] vitor_fs:
First of all, great work again with this kernel Stefan! I always use it on my stock rom. Now my problem. I cannot overclock my cellphone =/ Even I select in instalation to 1,2 ghz, or in the GUESTOC, it doens't work. But my ram goes to 404, like I selected, any idea how can I make this work?
[LG Optimus 2x] Stefan Gündhör:
FlixEdition is a special edition made for flix123 with different GuesteOC default values. The rest is the same, but flix helped me much in improving the performance of the kernel and provided his own toolchain, so he got his own edition with his preferred settings :)

Have you tried enabling init.d with Aroma installer? :)
[LG Optimus 2x] vitor_fs:
Yes, I tried 5 times. but nothing happens. In GUESTOC at system monitor the current speed shows N/A for both CPU.
[LG Optimus 2x] Stefan Gündhör:
Can you please try flashing a non-aroma package? Because Aroma package was built automatically and this time I didn't test it!

Also you might run the wrong BusyBox ... in post #1 I posted a matching one I believe.
[LG Optimus 2x] vitor_fs:
I'll try it right now Stefan, soon post the results. Thanks for the help! I didn't find anything about busybox on post 1#.
[LG Optimus 2x] Stefan Gündhör:
Right, somehow that got lost!

Recommended is Busybox 1.19.4 -- install it with JRummy installer, not a different installer!
[LG Optimus 2x] vitor_fs:
So I've instaled the Busybox 1.19.4 from JRummy installer, and instaled again with aroma instaler and it worked! Maybe some bug from the busybox! Thanks for the help man! Just one more question, which version have better battery life?
[LG Optimus 2x] Stefan Gündhör:
All HOC versions provide good battery! guestekrnL-chain does, flix-chain does and spica chain does as well! Currently recommended is spica-chain edition, second most recommended is flix-chain edition
