Using this kernel with MIUI for a while and it was working fine. Thanks for the great work.

Here I have a question, is that necessary to include superuser in the kernel? I know I can simply remove it from zip file but, that means from now on the people who using MIUI and wants to flash this kernel they must delete superuser.apk before flashing? The fact is MIUI using its own superuser which is not compatible with the one on the market.
[LG Optimus 2x] barmyman:
Hey, SetiroN! Well done, great kernel! Battery life is just awesome! But i want to ask you one thing: could you please create a version with 372 mb of SWAP? cause i can't create SWAP with your kernel(function not implemented)

Thanks in advance!
[LG Optimus 2x] miina_tokiha:
update:

I don't know what I did, but now the 2nd core is active even at 655Mhz

the last thing I remember is change sim card & APN settings (+reboot the phone a few times).

sorry to bother you. my miss.

EDIT:

after backtracking, maybe I found the problem.

I don't know why, but when I using wifi, the 2nd core is not active at 655 & 912 (it only active at 1100 and above).

I'm using 2G/3G data now, and the 2nd core back active even at 655.

this kernel is swap free.

it's already very fast, and the last swap ver I tried just slowing down the system.
[LG Optimus 2x] CVonV:
i'm thinking of installing this kernel after hearing good things about it.. but i've never flashed a kernal before.. i'm coming from temasek's cm7 204 build 33 rom

i would to know exactly what these ram hacks are for? ideally i do not want anything to stop working.. i just want better battery life (currently getting about 8-10 hours)

and perhaps a noob guide on how to install it please
[LG Optimus 2x] miina_tokiha:
same thing with flashing cm7 zip.

install zip from sdcard, choose the zip kernel.

wipe cache & dalvik.

reboot.

oh, you maybe want to read a few pages back if you want to delete any unwanted apk & bootanimation.
[LG Optimus 2x] SP1996AC:
These ramhacks will give you more RAM memory for your phone. This however comes with a prize because the bigger the ram hack the more things won't work. Look at the OP for the list of things that won't work

Sent from my LG-Stone from the Prehistory....

Naaaahh... Just kidding!

CM7.2 Temasek KANG P204-30

Ironkernel (Vadonkas KANG)
[LG Optimus 2x] Medizinmann:
Hello!

Well 1st read the starting post...

2nd as written in the starting post, you install the kernel after you installed the KANG and gapps through cwm like you installed KANG/gapps before. Then you should clear /cache and dalvik cache and reboot.

Reboot may take a few minutes so be patient it is not a boot loop as long as its no more than lets say 5minutes...

With 32MB ramhack everything should work except reboot - one thine one could live with. I had a little distortion on playing 720p videos in web-browser - but with the most recent version even this works too and I never had a problem with 3D games not working on the 32MB ramhack. But it speeds up things considerably - 32MB extra are a fine thing...:cool::):D

EDIT: miina_tokiha and SP1996AC were faster...;):D
[LG Optimus 2x] happyassshit:
So I don't have to worry about messing up the nand (lifetime)?!
[LG Optimus 2x] CVonV:
thanks guys... is there a 0mb ramhack? i kinda use the reboot option more often than not actually
[LG Optimus 2x] nfin1te:
I can confirm that, games run much smoother when im on 3g instead of wifi. Funny thing that. I already wondered why 3d performance was so sluggish.
[LG Optimus 2x] SetiroN:
Forgot to upload it yesterday, sorry... Core1 activation threshold lowered.
[LG Optimus 2x] yukkio:
I love your #31 version, smoother and good battery life.

Br.
[LG Optimus 2x] Sckank:
Any way to get the supersmooth scrolling like in Gueste's ROM?
[LG Optimus 2x] isd88:
hi,i love your kernel...and i will pay an app to change ram and gpu frequency (and maybe voltage). can you please consider my idea?
[LG Optimus 2x] Medizinmann:
No, there isn't...

But it isn't so bad just shut down and start up again - and if you want to go to recovery - hit go to recovery and after the phone shuts down start up will lead you to recovery - without pressing power and volume down simultaneously. It is only one press of the (power)button more...;):D

If you still need reboot so desperately - you might look in another kernel project.

---------- Post added at 10:34 PM ---------- Previous post was at 10:30 PM ----------

AFAIK setcpu is working good with this kernel.

But I would only change the top speed (I use 1.3Ghz most of the time) and therefore free programs like AnTuTu cpu master are enough. The kernel already undervolts to a certain extend...
[LG Optimus 2x] 2Kings:
Please supply also the 00mb hack

with the 32mb, my VPN doesn't work and they are often connectivity issues with the google sync (over wifi at least)
[LG Optimus 2x] afpapa:
I think he asked about GPU not CPU OC. :confused:
[LG Optimus 2x] isd88:
yes, i'm looking for GPU ( bat also AVP, RAM, etc etc) overclock/underclock. I don't know if i can change these values at the fly but also if a reboot is needed it will be very useful to uderclock GPU for normal use and overclock AVP when i think to watch a full HD video on my tv via hdmi. I use system tuner pro and i paid it something like 4 euros but is so useful! with this app i can change voltages and frequencies for all of the states of our double A9 cpuv whith great improvements in battery life. i think also gpu, ram and avp control could be as useful as cpu control.....

ps: as far as i can see you use kang version of CM7....i tried it but the system was almost unusable, all smoothness of CM7 disappeared and quadrant score also decreased..... do you think i made something wrong during installation?
[LG Optimus 2x] nfin1te:
Please stop asking for versions w/o ramhack 3times per page, currently there aren't any. Any new infos on lowered core threshold from new version instead?
[LG Optimus 2x] afpapa:
It runs perfectly on my device.

What my (limited) experience teaches me, is that when changing a type of rom, a full wipe solves all these problems. And restore only user apps, never system apps and system data. (reason of many problems for me at at the beginning)

I am running for over a month now the kangs, always have scores in antutu over 7300@1,5GHz. Toped @ 7525!!!. I don't use quadrant any more, it is not reliable. If you use it you have t run it at least three times in a row to get a good result.
[LG Optimus 2x] isd88:
i tried again but normal CM7 + ironkrnl gives me the best framerate ! sometimes 50/80% more than kang :( probably there is something that i can't understand in configuring roms
[LG Optimus 2x] miina_tokiha:
try install Chainfire3D openGL driver.

get it free from market.
[LG Optimus 2x] SetiroN:
That can't be related to the ram hack, must be something else.

Nothing special, lowered from 912MHz to 655MHz as requested.

It's not really worth the gain...
[LG Optimus 2x] isd88:
better than walking :D and also a way to pay you for your nice work....now my p990 seems almost a sgs2 (that i had before this ...)
[LG Optimus 2x] Medizinmann:
Yep, sorry over-read this...:eek::o:D

Well, AFAIK SetiroN already overclocked GPU/AVP/ram to a certain (still save) extend and AFAIK more would/could break things like instabilities in camera,hdmi-output, audio, 3D etc. and so on...

There are kernels with higher OC of AVP/ram but some things don't work.
[LG Optimus 2x] denexo:
Thank you SetiroN for your kernel! It works amazingly fast, incredibly stable! Keep up your excellent work!
[LG Optimus 2x] isd88:
hi, i know but it could be nice to control multipliers or frequencies of video side of tegra 2.
[LG Optimus 2x] 2Kings:
i just noticed that with the last 00mb kernel it was working, but with all newer 32mb, it didn't.. changing back to 00mb resoled the issue

I'm using Any connect root (for cisco vpn)

anyway, worst case i'll stick to the last 00mb version
[LG Optimus 2x] -=Beavis=-:
Hey guys!

Trying to get this kernel running on cm7 kang 34. I start in recovery, install the kernel (newest 32mb version) from sd. After that I wipe the dalvik cache, format the cache and boot. After a while android boots and loads my sd card- i get a freeze, black screen and the device restarts! This unfortinately with every version of the kernel (only 32mb versions).

Running 823 baseband- might this be the problem???? In an earlier version of the kernel I had to remove the sd card from the device for a smoother non freezing experience! Any suggestions?

Thanks for helping guys!
[LG Optimus 2x] miina_tokiha:
cisco vpn should get advantage with bigger RAM.

I wonder why.

what sdcard class you're using?
[LG Optimus 2x] -=Beavis=-:
I'm using a 16GB class 2 card- no issues with it so far (recording 1080p etc) -> only with this kernel!
[LG Optimus 2x] miina_tokiha:
actually class 6 or higher is recommended even if you use vanilla CM7 kernel.

using a highly tweaked kenel like this, lower class sdcard can't follow the performance.

it can freeze, restart, even died on some cases.

of course this only my opinion.

wait for SetiroN to clarify this.
[LG Optimus 2x] -=Beavis=-:
Okey thanks didn't know that (since I've never had issues so far)! I hope setiron can bring light into the dark ;)
[LG Optimus 2x] TheReino:
SD Card

Don't forget that those classes only show the min. performance in write speed which HAS to be achieved by the card.

May try the app "SD Tools" for speed testing...
[LG Optimus 2x] Medizinmann:
Hello!

Can't tell what the exact problem could be but the BB/RIL 0823 shouldn't be the problem - I use it since I use CM7-KANGs - meaning directly after nightly 204 which was released 16th Nov. 2011...;):)

BTW: I use a 32GB Class 10 card.
[LG Optimus 2x] xfakexbloodx:
sory noob question. could we used it with MIUI ??
[LG Optimus 2x] ppp0941:
Sometimes, I cannot switch my screen on after unplugging the headphone when screen off.
[LG Optimus 2x] miina_tokiha:
class 2 = 2mbps write min

class 4 = 4mbps write min

class 6 = 6mbps write min

class 10 = 10mbps write min

it could get lower if the card is full.

class 2 usually can get 3mbps average.

CM kernel uses a little tweak to boost the read/write speed.

and custom kernel like this, add more tweak to increase it further.

that's why lower class sdcard can't keep up.

yes.

unmount your storage first before unplug your phone.

or increase the 216MHz clock voltage to 775mv (this one cause instabilities if you directly unplug without unmount it first).
[LG Optimus 2x] afpapa:
Not correct, it shows the minimum guaranteed speed, not the maximum.

He said the headphones, not storage. :)
[LG Optimus 2x] miina_tokiha:
oh yeah, sorry.

I just woke up from sleep when writing that :p
[LG Optimus 2x] -=Beavis=-:
Okay thanks for the info I'm glad I don't have to install a new BB/RIL!

Furthermore I took the 16GB class 10 sd card from my dad. I did a partition via cwm in case of app2sd.

The system now runs more stable but I already got two black screens (by touching the screen the buttons on the bottom light up) and had to remove the battery to reset.

So here is what I did: Partition the sd card with cwm (256mb, 64 mb swap file) installed latest kang (38) system booted up- everything fine. Back to cwm I installed the 32mb hack ironkernel, wiped dalvik and formatted cache. Still two black screens as already said- am I the only one left with sudden SOD?

Will report back after a day of use!
[LG Optimus 2x] miina_tokiha:
try to increase the 216MHz voltage to 775mv.

I think the 750mv default value from this kernel is too low for some device.
[LG Optimus 2x] -=Beavis=-:
Okey but how do I do that? With pimpmycpu I can only lower mV not increase....

My system runs now more stable but my home key and lock screen don't work!!!! Even after reinstalling cm7 nightly 204 and after that reflashing ironkernel- no lock screen and no working home button. Strange thing is that the phone still vibrates on pressing the home button so obviously the button still works(key test in cwm says the same)

Darn this thing drives me crazy!!
[LG Optimus 2x] miina_tokiha:
ah, now that you mention it.

we can't increase the voltage using pimpcpu.

try update your cm built.

nighty-204 is old built.

try temasek KANG built.
[LG Optimus 2x] -=Beavis=-:
I did come from the newest KANG build but had the same issues... so I thoughtI might give the good old nightly a chance to iron out everything but nope :( I don't know I even did a factory reset this morning and since then I have a working rom and kernel but without home button and lock screen...

I'll try to reinstall the newest kang, install ironkernel do a factory reset wipe dalvik and format cache and hope -.-

EDIT: Did a clean install of both and it works now - had a few crashes though....but not as bad as before!
[LG Optimus 2x] morckx:
You can use "System Tuner" to increase the voltages.
[LG Optimus 2x] -=Beavis=-:
Okey thanks will try that! System now runs better I think there were some files on my sd card which misconfigured the installation of cm!

Edit: Anyconnect (root) doesn't work here too (32mb version)
[LG Optimus 2x] miina_tokiha:
update:

confirmed phone freeze when disconnected from storage mode if 216MHz set to 750mv.

but no problem when phone used daily.

775mv is a safe bet for most people.

regarding 2G/3G connection, I notice battery would last longer when data set to GSM/WCDMA auto mode.

phone will automatically switch seamlessly between 3G (when idle) and H (when data load).

when using 2G/3G toggle app, phone often switches mode causing more battery drain.

plus there is delay between modes.

I'm not using this app anymore.
[LG Optimus 2x] nfin1te:
No probs here with 750mv.
[LG Optimus 2x] tomsi91:
How does it work? The new 104XT and 112XT ram hack? Does the GPU have any memory?
[LG Optimus 2x] grognaz:
thats why my class 10 can hardly brwak the 6mb/s barrier....
[LG Optimus 2x] tomsi91:
112XT kernel is freezing all time. not usable at least with last temaseks kangs.
[LG Optimus 2x] afpapa:
As I'm realllllllyyyyy happy with the 13th of January kernel, is there a good reason to update?

As I'm too stupid to understand the changes in the log. :o

I see some UV adjustments, lower CPU1 activation threshold, the 104 ramhack and some name changing - corrections - comments. That's all I understand/....
[LG Optimus 2x] miina_tokiha:
not much change.

lowest 216mhz voltage increased to 775mv.

I set 216mhz@750mv only at screen off mode to avoid freeze then unplug usb storage.
[LG Optimus 2x] Medizinmann:
Hello SetiroN!

Again thumps up for the good work!

I bought a new bluetooth Hands Free-Unit(ViseeO MB-3) for my new car(old one from blaupunkt isn't working with the cars stereo) and cannot connect to it. I tried ironkrnL, CM7 standard kernel and pure stock with an unchanged phoen using LG Stock v20l. No paring or connect possible.

It works fine with my old Sony P1i and I can connect the o2x with ironkrnL to any other bluetooth device I could find i.e. A2DP headsets other phones etc.

I read there could be a problem with the ViseeO MB-3 with a missing DUN(DialUP Network) module in some Android devices.

Is a DUN module included in the kernel? Or is it possible to include one?

Thanks very much in advance!:)

EDIT: A Firmware-upgrade for the MB-3 did the trick - it was supposed to be only for users with Samsung Galaxy phones, but I thought give it a shot and it worked...;):):D
[LG Optimus 2x] miina_tokiha:
just tried the 112XT ver

user RAM is huge.

system is very responsive.

but camera don't work and I doubt heavy games will work.

revert back to 64M ver.

oh yeah, compass already work now.

latest 19 jan release.
[LG Optimus 2x] jalankakapsatu:
i use 3 of them but no one works,im using cm7 nightly 204 n cm7 rc1,none of them works

sorry for my bad english

edit: sorry its only works for cm7 kang?
[LG Optimus 2x] SP1996AC:
A cm nightly is indeed very old so try a cm kang instead.
[LG Optimus 2x] miina_tokiha:
yes, nighty-204 is old built.

7.1.0-rc1 even older!

use newest cm-kang that can you find in this forum.

there are vanilla built (in CM KANG thread), or cherry picks built (by temasek).

their version is the newest 7.2.0-RC0 built.

almost no bug left, just add some feature on each update.
[LG Optimus 2x] jalankakapsatu:
i already use cm7 tamasek but still stuck after LG logo

already wipe cache-wipedata-wipe dalvik

any solution?
[LG Optimus 2x] miina_tokiha:
1. install cm7 kang

2. install kernel

3. wipe cache

4. advanced > wipe dalvik cache

if you already did it in order, it should be fine.

1st boot is always long (2-3 minutes).
[LG Optimus 2x] Medizinmann:
Hello!

I always format /system to.

No need to format /data so.

My standard procedure is as follows:

1) Format /cache, /system.

2) Install latest KANG

3) Install latest gapps (also to be found in temaseks mediafire account)

4) Install kernel

5) Wipe dalvik cache.

6) Reboot and wait a few minutes - 1st boot takes some time!
[LG Optimus 2x] jalankakapsatu:
still didn't work,stuck LG logo
[LG Optimus 2x] afpapa:
Then you have to do a factory reset, to clear everything and try again. (you will loose anything you had not backed up)
[LG Optimus 2x] ron_gangte:
What are those two new versions with "TX" in their names? :-\
[LG Optimus 2x] jalankakapsatu:
i did all of it...but still stuck n LG logo

i'm getting frustated,heuheuehu...

when use only the rom it works,but after install the kernel,its stuck

before this i use cm7 nightly 204+swiftextreme n works well...

but why oh why...i wanna try this stuff... :((
[LG Optimus 2x] miina_tokiha:
that's strange.

try if this one works:

http://dl.dropbox.com/u/39242124/ironkrnL64-20111202h23v3.zip

or

http://dl.dropbox.com/u/39242124/ironkrnL64-20120104h2029.zip

that's old built, but it has higher voltage.

if it works, that's mean your phone can't handle the low default voltage this kernel have.
[LG Optimus 2x] jalankakapsatu:
first kernel it can get in but unstable n get turn off automatically

when i using swiftextreme with cm7 kang rom,it works...
[LG Optimus 2x] miina_tokiha:
ok, that's really strange....

what sdcard class you're using? (don't tell me the brand is v-gen)
[LG Optimus 2x] jalankakapsatu:
nope,TEAm 16g class 10

the more weird is when i install the switch extreme it works,before i install swiftextreme, i install ironkrnl first, i'm forgot but i think i didn't wipe at all

after reboot-LG logo-2nd LG logo-there are screen like computer strat up..energy epa,etc...just like when u start your computer-bios...my device blablabla...n detect ram hack...

and ironkrnl bootloader...n get in,it works...

strange or not???

in about: there are switchextreme kernel...

but the batterylife i think its not like swiftextreme...its better...maybe ironkrnl combine swiftextre by itself,hweheuheu...

i'm confuse,heuheuheu...
[LG Optimus 2x] hardmankam:
I have the exact problem!!!

Currently I am using the CM7Kang-P204 Built42

When I install the ironkrnl kernel after the CM7kang ROM, it will hang at the LG logo screen. I have tried many different versions and it is the same.

However, if I then install the swiftextreme kernel (without wipe cache) right after flashing the ironkernel, then it will boot up normally.

The great thing about this is that the 32M/64M/96M ram hack (from ironkrnl) works and the OC/UV works from the ironkrnl, thus the best from both worlds.

Of course if ironkernel works on my phone, then I will just use that instead. This problem exist for some phone owners here in HK. (discuss on a local forum).
[LG Optimus 2x] ragiut1:
did u disable boot animation in CM settings?
[LG Optimus 2x] hardmankam:
Tried it with both boot animation on and off ... no go

also after a clean re-flash of cm7... no go

still stuck at LG logo upon boot up if i flash ironkernel only.

This happens to my phone on a few other ROMs and Kernels as well, so I suspect that it is a hardware compatibility issue. As I have said earlier, this happens to a few LG owners locally as well.
[LG Optimus 2x] Mungulz:
whatever you did in a recent update has made all the difference. About a month ago I couldn't use this kernel because gmail crashed. It works now, and I can get 80+ hour runtimes with no issues. I used to have to reboot every few hours.

you've made my phone reliable again lol.
[LG Optimus 2x] miina_tokiha:
that's really strange.

I haven't get any major problem with this kernel since 2012 update (all of it).

have you tried change "Setting > Application > Development > Stay Awake" to ON?

that's resolve most of my problem.
[LG Optimus 2x] SetiroN:
whoops, I accidentally forgot to save the updated zipper and all packages ended up with scripts 80 and 81 instead of just the XT ones. Fixed, now if you want them you'll have to move them up one level from the /extra subfolder.

Sorry for being so absent but my life is a mess more than usual, and the thousand word post I had written got lost in a power outage. I got like 10 PMs, besides thread posts, to answer plus the updates. Not to mention the lot of actual kernel stuff. Sorry, I'll do it when I can.
[LG Optimus 2x] miina_tokiha:
I've been using this kernel for 2 days now.

set 503MHz as min freq really do the job.

voltage set to 700mV @503MHz.

600mV is just too low.
[LG Optimus 2x] SetiroN:
- updated.

Nov29.07am

- Still, for some reason, TinyRCU > JRCU - who knows why.

- Replace 816,1015MHz with 912,1100MHz, reduce low clock default voltages

- Rebase and squash last commits: …

Overclock DDR, AVP, VDE

Fix Sleep Of Death when undervolting

Disable touchscreen Grip Suppression

Tweak board voltages

Also, I've removed the zipalign/database defrag script.
[LG Optimus 2x] vadonka:
thx, testing...
[LG Optimus 2x] fire3d:
thx - downloaded and testing it now
[LG Optimus 2x] fire3d:
should that display 1100mhz instead of 1015mhz in PimpMyCpu?

if yes, for me it doesn't

Sleep of Death happened to me @ 216mhz without UV
[LG Optimus 2x] miina_tokiha:
have you try to del all the profile (pimpmycpu), then make the new one?

if not, you will still get the old bug.

I've tried to sleep my phone @216MHz, 525mv.

no SOD so far.
[LG Optimus 2x] _Vegas:
oh..525mv?
[LG Optimus 2x] miina_tokiha:
current setting I tested...

I can't say much since just an hour or so...

we'll see tomorrow.
[LG Optimus 2x] nfin1te:
Afaik it can't be lower than 750mv by HW-defaults.

You can even set 100mv and it will be stable, because it's always 750mv min.
[LG Optimus 2x] miina_tokiha:
aaah~~~

now that's explains it.

so I just need to set 750 as min, then rum stability test for higher clock.

thanks man.
[LG Optimus 2x] SetiroN:
You must have downloaded or flashed the wrong package, you are still on the old kernel. :p

770 on stock roms

750 on vork

700 on iron

:)
[LG Optimus 2x] fire3d:
yes, i have deleted all profiles, still shows none of the new

frequencies
[LG Optimus 2x] SetiroN:
Again, it's not a profile issue, you have the wrong kernel.

Download it another time...
[LG Optimus 2x] Thief777:
Stable kernel recently? Share your experiences!
[LG Optimus 2x] przemchess:
I've two strange crashes with latest version:

1. When connected to my pc and browsing this very thread phone just shut off it self. I've seen screen with battery charging. So I've simply turn it on.

2. After ending a phone call I've received sms and then phone just froze: screen was on, touch buttons was bright. I've needed to remove battery.

My settings was:

Min freq: 503

Max freq: 1312

voltage -100 mV for all steps
[LG Optimus 2x] nfin1te:
Well you should remove cpu profiles first, or is it there because of a bsod?

Also, try it on stock voltages first if those problems still occur.
[LG Optimus 2x] fire3d:
i think it was a profile/pmcpu problem, i deinstalled pmcpu and rebooted the device,

installed pmcpu again and it shows the new frequencies ....

---------- Post added at 09:53 PM ---------- Previous post was at 08:56 PM ----------

got a couple of SOD's with the latest kernel, also the

phone gets relly hot when this happened ....

reverted to the "old" good kernel

in my opinion the 216mhz as min is not worth the energy savings

that i get .....

Also, i set my WLAN to always on, saves more energy as the setting that will switch Wlan OFF when screen is off .... (i have read this anywhere here in the forum)
