Hi all
I run XXKI3 2.3.5 on my samsung galaxy S2, I am wondering if there is a tried and tested way of Overclocking this at all. I have seen some write-ups that say I need to roll back to 2.3.3 so as to use the overclock essentials with Odin. I am not very much keen on rolling back to 2.3.3 as 2.3.5 is really cool. Any help and advice is welcome
Didnt you try a Custom Kernal?? Stock kernel may be sometimes not support.. Me also had some problems like this on my X10 Mini Pro. I flashed a custom kernel and now Overclocked From 600MHz to 768Mhz. Working smooothly..

I have flashed the stock kernel but when I use galaxy s2 overclocking essentials my phone won't fully reboot so I have reverted back cf-root. XXkI3 just wont work with the stipulated files for overclocking essentials. I really want to overclock my SGS2.
You need to use a custom kernel capable of overclocking..
Lowandb can you link to one so i can download if there is one you may recommend
use tegrak
Cfkernel, villainrom 3.0 and setcpu. Running at 1.6ghz here with zero problems, and a quadrant score of over 4500!

hello,
I'm using the official lg rom v2.2.1 that came with the phone. I wanted to update to cm7 but I read about the problem with the BT wich I must have. another thing is that I'm using hebrew and I need it to stay that way.
The thing is that the touch screen is very bad and lags a lot.
If I will upgrade only the kernel what will be the affect on the phone and how do I know what is the best kernel for my version ?
In general I want to fix the touchscreen bug and to OC the phone.
thanks for the help.
If you just want to overcome the touch screen bug then I would suggest using Der_Caveman's Kernel, it is quite old but is usable and removes the touch bug and enables OC.
The kernel wouldn't change any outward appearance of the phone, except maybe increase the quadrant score a bit. If you really want a good performance boost as well then try franco's kernel. Since you are using the stock rom it is recommended to take a nand backup before flashing these kernels. And a kernel doesn't change the system language AFAIK.
Thanks for quick reply. will these two kernels good for froyo 2.2.1 and are there known bugs that I should be aware of before updating ?
As far as read the franco's v18.1 is for 2.3.3...
I have never used Der_Caveman's kernel, but it is bug-free AFAICT. And in the link that I have posted above, franco kernel is available for both froyo and GB. Download the version that says "franco.Kernel v8.1 CFS", it is for froyo.
And as I said earlier, since you are on stock rom it is advisable to take a nand before flashing a custom kernel.
i used dookmatt's kernel which was really good for me(flashed it on stock 2.2.2)...i had no touch lag, no bugs. that would be my recomandation
also dont forget nand backup is holy!

Can I OC with this one ?
OK, I flashed Der_Caveman's Kernel and so far it looks good. the touchscreen is better and I OC to to 729 using setcpu though I cant tell the difference in terms of the speed.
how can I tell if its really 729 and not 600 ?
thanks.
yes my O1 ran at 787 mhz and it was darn stable(at 800+ i had frequent freezes and reboots when launching apps). i also had a friend of mine install this kernel and he's happy with the "new" phone i made
quick system info on market...shows cpu speed
You may look at info tab on SetCPU, it says alot about your device, CPU (frequencies and features), battery and so on.
And you can have SetCPU widget on homescreen as well, which shows current freq, min and max frequencies of the governor you're using

I'm still stuck at Froyo 2.2 KB5 ROM (Project V with Bali-X) but I want to try a new one GB ROM. Everything seems to be working well there but I can't find information about undervolting possibility on GB kernels. Even tegrak overclock doesn't seems to be working with them.
Pimp My CPU or Voltage Control works well for UV with the Glitch kernel for GB.

First, you need to be running a kernel that supports UV. I'm not sure if any of the Samsung based rom kernels support UV, but if you go a CM7 based rout, glitch v11 is insanely good at UV.
If you go CM7, make sure you Odin back to the froyo bootloaders first, as you wont be able to see your external sdcard.
Also, make sure you read the CM7 dev op carefully and read the CM7 q & a op carefully to know what most of the bugs are before you flash.

I recently installed the endv2.5 rom and it was oc so was a bit nervous about it as i know it can damage the phone. I have a wuestion and a request.
First, What are the dangers of oc your phone and has any of them happened to you (are they common)?
Last, can anybody post a link to where i can find a non oc kernel for the endv2.5 rom?
Thanks
as far as I know only CM7 Kang by vo-1 is the only one that has a non-oc kernel.(if i remember right)
aaand ATM there is NO STABLE OC KERNEL so it can fry your motherboard, brick it beyond repair, and with taking the risk of OC-ing u changed to custom and custom rom pones are warranty voided so pretty much your ace will be killed at high frequencies. (stupid samsung OC'ed ace's processor but wont let us OC it >.<)
ok so dont oc the phone lol i dont see why dev's oc them if its do dangerous.
Where can i get a Kerenl to flash that is not oc'ed.
There are a list of kernel's here (http://forum.xda-developers.com/showthread.php?t=1439516) but not sure which one to use?
Flash the zImage-Mod v1.0 (1.0 is better then 1.1).
where is the zimage and what does it consist of
just had a read of it and seems good.
It is non oc ye?
and are there any bugs or problems with the v1.0 kernel?
No bugs, works perfectly, should work on all CM based rom's, and it doesn't have OC.
im kinda nervous to do this lol
if it doesn't work can i just simply reflash the rom am i using and the kernel will be restored?
and how do i open govenors?

Backup before u flash anything just to be safe
thanks. Tried it out and works fine though i have backups if anything happens
Im using Omega Rom v23 and i just installed SetCPU.
Can someone explain how i go above 1400mhz? it wont let me choose a speed higher?

You need custom kernel. But dont have any custom kernel to work with JB what you can overclock.
Enviado do meu GT-I9300
use an o/c kernel.....no I won't suggest one
Go to development and read
As far as im aware omega 23 is custom stock rom. JB ect.
to unlock overclocking you would need a a new boot.img withunlocked overclocking
that wont be out for JB roms until the source is released.
You would have to install a earlier rom if you want to use a costom boot.img with unlock overclock.

What Kernel does that ROM come with? Is it the STOCK kernel? If so, you CANNOT overclock the STOCK kernel at all and can only overclock CUSTOM Kernels that have that ability built into them.
More info from you is needed...
It seems the JB Rom from Omega doesnt have this overclocking unlocked

there won't be any o/c kernels until Samsung release their source code after jb official release
I own a GTi9300 4.1.2 XXEMC2 rooted but still on stock (didn't find any advantage in any custom ROM so far) i rooted it using CFautoroot.. I didn't install CMW yet using ROM manager, but im willing to once i find a kernel that will let me overclock my phone.
So any adviced Kernel that will work on my phone to overclock? Currently SetCpu only allows me to underclock :/.
Thanks in advancee
N. B: I DONT OWN A MEMORY CARD IN CASE ITS NEEDED TO FLASH A KERNEL
check the development section for compatible kernels. all of them allow OC

Siyah Kernel up to 1.8 GHz. What app is great is stweaks it allows to select how many cores u wanna use also has a build in sound equalizer and many other cool things. But u need Siyah kernel installed for it to work.
