I use samsung galaxy mini !! I have amdroid 2.3.4 on my phone !! I m using stock rom !! So there are any chance to overclock my device without custom rom ?? Pls i need some help !!
I don't think it is possible without root access and at least a custom kernel. See the forum section listed with your device name in the title for detailed information on how to obtain these and your overlooking dreams, with a little research, just may come true.

Actually, it IS possible to overclock without a custom rom. The rom is not the problem. It's the kernel. As long as you have root access, all you need is a custom kernel to be able to overclock your device.
ok here's my query. i have a custom rom, i got root and its normally overclocked and no harm on that.
however, i have an enterprise email app that only works when the environment is not rooted.
so the solution is the script that temporarily takes out root, reboot, and upon bootup phone is compliant and can run the app.
hence at this point, the phone is unrooted until i run the revert script that brings back root (but i cannot use the email app).
At stock speeds (1Ghz), the general feel is the device isn't that fast (probably i was used to 1.4Ghz speeds). its tolerable though.
so my question would be, is there some file or something like a tweak in build.prop or whatever, that can be modified/set while in rooted state, to make the default speed to be overclocked (and adjust the governor and i/o scheduler as well to my preferred ones). so when the unroot happens and phone reboots, it keeps that clock speed.
thanks in advance for replies.

Hello all. I'm about to bombard you with a few noob questions that I'm really hoping someone could help me out with.
I'm currently using a Galaxy S2, but after reading a bit about custom ROMs and the ability to possibly increase battery life among other features, I have decided to delve a bit deeper. I do have a few questions though.
- What is the difference between rooting and using a custom ROM?
- Do I need a specific Kernel version or build number in order to use a custom ROM on my Galaxy s2 or does none of that matter when installing a new ROM?
- It is to my understanding that custom ROMs cannot use Kies. So, in the event that Android 4.0 comes out, will I have any problems being able to get it onto my phone with a custom ROM? Will it cause any interferences between the ROM and the new operating system?
I'm very interested in trying this out, however with the firmware I am currently running, there is no replacement to be found. In the event that I want to revert back to factory, it probably will not be possible to find this specific firmware that I am using (already searched).
Thanks a ton in advance for the help
Rooting gives you access to aspects and features on the phone that you otherwise couldn't get to. Installing a custom ROM wipes out the software on your phone and replaces it with software someone other than the OEMs developed.
You need to unlock your bootloader in order to install a custom ROM, and the process for this differs from phone to phone. Other than the different steps, it doesn't really matter what your phone has to start out with.
I don't know anything about Kies.
Honestly, I would highly recommend rooting your phone... just make sure you maek a backup as soon as you get root access (but before you install a custom ROM) and you're good to go!

There's probably a for for the GS2, where you can find details for your phone. Some methods of rooting on some devices do require a specific version of firmware. Give or take carrier issues I heard the GS2's were getting ICS in an update...
The main reasons to root your phone are to do things you can't do without root. For example using a VNC server you typically requires root, but it allows connecting to your phone via VNC. Custom ROMs are usually rooted; installing a custom ROM doesn't always need root (e.g. nvflash) but it helps eventually.
No idea what Kies is and I'm to cold to Google it. If it's in the market, check it in a browser to see what versions they support.

Hi Guys as my title Says..
i need Help very Badly.
First of all MODS and USERS i'm sorry i didn't knew where to post this thread so if its in in-appropriate section please move it to correct section. THanks
OK my problem is this.
i recently (less than a week ago ) bought a Samsung Galaxy S2 its by Bell Canada and its i9100M. i bought it online since my service provider is Rogers.
i guess this phone is already rooted to unlock it and i can see CWM and SU icon there.
Well i'm a Hardcore Blackberry Fan and have been using Blackberries from last 6 years. I loved the new samsung because of it looks and its screen.
I Had Lot of Problem with it like setting up my yahoo as push email, setting the Ringtone Profile, setting up the Custom Ringtones for Text Messages..
Having wrong time stamps on Recieved TEXT Message.. well i fixed all those by installing apps from market and forwarding my yahoo to my gmail...
i Hated doing all that but infront of the beauty of this phone i had to compromise but today it took 3 hours to find my gps location and day by day im using it i'm hating it .....
SO OK I DID MY RESEARCH AND FOUND OUT ALOT... the more i'm researching the more i'm getting confused...
first of all what is the difference between custom ROM and KERNEL.
i know custom rom could be like operating system but customized by unofficial person.
what the h is KERNEL..
to install rom's or kernel do i really have to root.
To unlock do i have to root or is there a paying method.
also i want to know if i'll go back to stock rom can i still unlock it.and recieve all the updates from samsung or google specially when ICS will be launched.
after unlocking and installing custom root. can i unroot it
and lastly which is best custom kernel and which is the best rom availble.
since been a blackberry user i have very basic needs. i don't play any games or download much apps and if an app is paid..i'll pay for it.. i don't want to jailbreak anything .
all i need is better battery life, gps and network coverage.
Thanks for taking time to read and reply.
Hi there.
I'll try and get through your questions as simply as possible,
Imagine your phone is like a car
A kernel is like the engine of a car - it's the low level machinery that keeps it going.
The Rom is like the body of the car around the engine. Roms can be official (or Stock Roms), or they can be customised by other people.
So, when you install a stock rom - you're installing the kernel, but you're also installing the radio (called a modem or baseband) and the registration (or the CSC which is location specific information) as well as the unique 'body' of the car for that rom - tweaks, default software, etc.
You don't have to have rooted your phone to install a Rom. When you update your phone via Kies, you are, literally, installing an stock rom. You can even install stock roms from elsewhere without rooting your phone. Because stock roms are released in different regions at different times, lots of people update their phones to the latest official roms via this method - no root required.
However, to install a custom, unofficial rom, you will need to root your phone as they will require access to the 'root level directory' of your phone's file system - which is what root really means.
You can find everything you need to know about that, how to root and also lots of stock roms you can install without rooting here:
Some shops will root you phone for you if you want to go down that path and don't want to risk it. But it's easier than you think and the galaxy s2 is very hard to break. There's lots of help available on XDA - just remember to search before you ask so you don't ask a common question the millionth time.
If you have installed a custom rom you can easily re-install a stock rom over it that will still work with Kies and thus be updateable when ICS turns up.
There is no 'best' Rom or kernel. Some Roms go 'as is' and some are customisable to the nth degree if you like fiddling with your phone non-stop. I personally use CheckRom because I like the kitchen app that lets you swap kernels, modems and mods with ease - but check out the Original Android Development threads and see which other roms you like the sound of.
Depending on what you are currently running, a new rom - even a stock one if you're running a very old one - could easily help with battery and range issues. For GPS - try installing FasterFix from the market and see if reassigning your GPS fix to a closer location helps.
Best of luck - it's a great phone once you open up its possibilities
Thanks a lot for the reply
well your reply did help me a lot...
my phone is been already rooted by someone else already from the person i bought it....
as for searching i did a lot.. and its been confusing me more and more ..well thanks for your answer
also as u said S2 is hard to break..i guess u mean is that the JIG thing on EBAY
and as for flashing the stuff i've played with other stuff just not android thing ive replaced the os on BB and jailbreaked iphones and installed macintosh on HP PC and also worked on most of the languages 10 years ago... and i believe nothing is impossible so going to someone else is never an option for me
just want to know as much as stuff i can before going further
well i have few more questions
how can i find which rom or kernel is already installed...
i mean is it possible to tell if its stock or its customized and its customized by which group.
and one last thing.. u know the words u used modem and baseband...
i read about it before...
but my question is ...
IS THE BASEBAND ANYTHING LIKE IPHONE BASEBAND???
u know in iPhones when baseband is updated u r screwed sometimes its hard to jailbreak and definately hard to unlock and reverting changes to baseband....
is it the samething in Galaxy S2 as well...
Thanks a lot for replying...i really appreciate all the time you took to reply.
Thanks once again.
Yeah baseband is the code that handles the phone part of your smartphone. Talking to your wireless provider, 3G, texts all these things are done by baseband.
Flashing a different baseband won't screw your root, and you'd still be rooted. Samsung doesn't make it hard to root as Apple does to jailbreaking. Even if something goes wrong with a new version, you can always revert back to old one using Odin(Samsung ROM flashing tool) and you are good to go.
Thanks a lot... about that quick reply...
i'm gonna collect more information and hopefully i'll be flashing it on weekend...
but how can i find which rom or kernel is already installed...

Everything you need to know can be found here. Most of it, anyway.
Backup your device with cwm when rooted ... So you can always restore to previous state. ;-)
Good luck there. But reading is a must.

Setting went wrong when quoting

also you can go settings - about phone - then look at the bottom fields to see kernel, baseband and build. Quote those and we should be able to tell what you have.

Basically what I'm trying to do is make an insecure/rooted kernel and a custom ICS ROM for the Samsung Galaxy Player 3.6. I don't have enough knowledge and experience to do this completely on my own, so if anyone's willing to help that would be great.
For rooting I know that because it's 2.3.6 there's no universal way to root. I've heard that the only way to root 2.3.6 is by flashing an insecure, or rooted kernel, while I'm savvy enough to flash the kernel and/or provide the files, I have no idea how to build one.
For a custom ICS ROM it's the same, I'm savvy enough to flash a ROM and provide files, but not even close to knowing how to build one. I'd like the ROM based off of CM10, if possible.
I'm willing to test out anything remotely stable that doesn't have a large chance of bricking my device. I know the amount of people who are interested in this is small, but we will all be very grateful.
I thought most custom roms automatically allowed the user root access. After all, managing users and permissions is a function of the kernel, which gets replaced when you flash a new rom, doesn't it?
Of course, there is a very good chance I'm mistaken or just wrong. Either way, this is a great chance to learn the how's and why's of droid development.

Sorry if it didn't seem clear, but in the end I'm wanting to create a custom ICS ROM, but right now I'm wanting to at least root.
I just updated to ICS using the OTA, i'm S-OFF but stock otherwise. I use Droidwall and now that Tell HTC is forced on I really want to keep it active. A small problem is that the LOG target for netfilter/iptables is missing in the stock rom. It should be simple enough to get the module version and put it on the phone. I used to do a lot of custom kernel builds on servers for Linux, but I'm out of my depth from an Android perspective. Is this even possible, or will it take a full custom kernel? I've searched on XDA and googled this quite a bit and I can't find any leads.
https://code.google.com/p/droidwall/issues/detail?id=96
After searching for weeks on end I have finally given up and decided to ask for assistance.
I have a Samsung Galaxy Player 3.6 USA. It runs Gingerbread 2.3.6 and I'm using a stock rom that is rooted which I obtained from here: http://forum.xda-developers.com/showthread.php?t=1864741
Now, in order to overclock I am well aware that I need a kernel that will allow for overclocking. I also need a kernel that supports my specific device and my Android version. With that, I have Googled, searched here, and pretty much looked in every crack of the internet trying to find a kernel that works. Out of sheer frustration I had actually trying out Tegrak Kernel, which failed miserably but luckily I kept the link above handy to restore my device.
I understand that there have been many issues with trying to develop on this thing and that the community is very small for this device. I see people overclocking their 4.0s and 5.0s and it really disappoints me that other versions can be overclocked but this one can't [at least to my research]. I have looked through these forums up and down and can't find crap. Rooting was difficult enough until I found that one post, and now overclocking is proving to be almost impossible. Is there ANY overclocked kernel out there that would work on my device that I could have possibly missed? Is there any developer currently working on a custom overclocked kernel for this device?
Any help would be greatly appreciated!
