Sorry I am a noob and this may be a dumb question but.. I am trying to root a galaxy S2. I have found the thread about rooting however, this forum won't allow me to post my question there so I am putting it here.
This thread http://forum.xda-developers.com/showthread.php?t=1125414 talks about installing an insecure kernel, then back to the secure kernel and links to another thread with the kernels. The problem is, there are soooooo many kernels to choose from. Which do I choose?
My phone is i9100BKEU I am afraid to attempt this as I don't want to turn my phone into a brick by using the wrong kernels. And, to flash back to the original kernel, this seems even more important to get the right one.
I found the kernels here...
http://forum.xda-developers.com/showthread.php?t=1101671
Can anyone point me to the correct kernel or, an easier method? My phone is new and just arrived from expansis today and has the latest gingerbread on it.

I don't own your phone but you could try this: Attachment included
Just install on your phone and run
i have followed this tutorial
http://androidadvices.com/how-to-root-samsung-galaxy-s-2-i9100-tutorial/4/
and my phone rooted without any problems.
I have the KG6 kernel and wasn't able to find it anywhere.
But I installed Lightning Rom (wit different kernel) and it worked fine.
So I think any kernel close to yours should work?

That is what I am most afraid of is not having the exact same kernel. I have read that it isn't so important to have the same exact kernel when installing the insecure kernel, but it is more important when your finished and install the secure kernel back.
Are there any experts on this topic that can explain how important it is to install the exact same secure kernel after rooting? How close does it need to be?
I am having the exact same issue. Dunno whether to use a KE7 or a KF1 or even KF3 kernel, because the guys who went to the trouble of creating the insecure kernels for the community (Odia & Chainfire) probably didn't think moronic luddites such as myself would be wanting to use them, so it's not entirely clear.
My firmware:
PDA:KF3
PHONE: KE7
CDC: KF1 (O2I)
If anyone can clear this up for me, a lowly noob, my gratitude will know no bounds.
Well.. This is same tutorial what I tried and that superoneclick always crashes..
But thanks a lot guys, I think I will first try that gingerbreak, unless someone else has better ideas?
Well.. I have KDD and theres even a youtube video of how to root KDD version, but still can't cause the superone click keeps crashing. its so frustrating! I really want root my phone..

From what I've read [and I've been researching how to root my phone for the last eight hours without joy], Gingerbreak doesn't work with Galaxy S2. It worked on the pre-production models (that's why there's videos of it on youtube) but any phone that you or I have won't be compatible. The only way around is ODIN & an insecure kernel, but as I and the original poster both noted, figuring out which kernel to use is really confusing for noobs like myself.
Hmm.. well.. I have same problem. Maybe dev. Can help us noobs here?

I just PM'ed Odia, and he was very helpful. The kernel you need is the one listed under PDA in Kies "Firmware Version" info panel. Just download the corresponding kernel and it should work... My only problem is that ODIN3 is now crashing on me! Out of the frying pan...
I have same problem. I think I will first try that gingerbreak, someone else has better ideas?
Hi guys. Is it hard to root the A510. I don'twant to install a custom ROM, just get root access to run stuff like Chainfire and have a little more control over GPU/CPU performance.
How long will it take? Can some one post me directions or a link?
Thanks!
Is it so hard to look at the whopping 8 topics here?

To be honest, there's not much. Even them, I'm a noob at this stuff. So I would've thought a little more hand.
There is a rooting guide and a program that will root your tablet, all within these 8 threads...
Sent from my GT-N7000 using xda app-developers app
There are many discussions about this topic.
Ok wait. So once I root, can I then update OS OTA. Will root be broken?
Its not hard at all, and while you surf xda in general, notice that there is the website part of xda with many good articles about the rooting process and its pro's and cons.
Theres a risk with any tinkering under the hood, but the guides a mostly quite accurate at what to do and its requirements for the process, but you, and solely you are responsible for doing it.
Another detail you have to obey to a certain extend is the posting of requests for advices in general, is that you ask in the appropriate section, eg. Questions and Answers, and the other sub threads like accessories, developement, and so on.
But dont mind too much about your first initial misplaced questions, and the subsequent grunty answers, unless you do it repeatedly that is. We all started as noobs, but follow posting rules as your first lesson.
And for your last question; No, you cant be sure of anything working as it did before you rooted, and further, flashed CWM, removed stock apps, setting up tweaks and mods etc etc.
OTA's is often depending on stock recovery, so nope, root can be lost easily, or the OTA execution might not be successfull at all.

1. Rooting does not automatically give you the ability to control GPU/CPU
2. What from Chainfire do you want to install?
3. The above stuff is not "noobish", ie. if you want to do such things you really need to know what you are doing - so better first read a bit more about root
4. When you root, depending on the method you choose, be careful with any update and better, do not do any FOTA update. It might cause the root not to work after FOTA (on A510 you use an exploit to be able to root which may be fixed in newer releases), or even brick you device (see simoneser's update here)

Ok, another thing. Which is harder and longer process...root or flash custom ROM?
Also, if I root, is it possible to stay with stock ROM? All I want is root access. Or with rooting must I got custom?\
Additionally, whats the difference between root and bootloader unlock? If I want to use things like CHainfire and Titanium backup, is unlocking bootloader enough?
PS: I will really appreciate if I can get a link (I have been trying to find) where the whole root process for this specific device is shown. I saw the XDA thread but didnt understand much.

Root is entry level. It is usually more difficult to flash a custom ROM as you will also need an unlocked bootloader (which the A510 already has I think), and a custom recovery.
Root, in popular Windows terms, is simply getting administrator rights on your current PC.
Unlocking the bootloader, is like having the BIOS password as well.
If you need Chainfire and TB, bootloader unlocking will do nothing for you. You need root.
To get root, I believe A100's Mempodroid exploit works for the A510: http://forum.xda-developers.com/showpost.php?p=25036001&postcount=93
Hello
(sorry for my english)
I'm a noob in this world and i need some help.
In the past few days i've been reading a lot of posts in this forum but to a noob it's a little bit hard to understand somethings.
So, i'm using this topic to ask some questions. If there is another thread that answer all my questions and explain things for a newbie, feel free to tell me and apologize to create this new thread.
I have a smartphone android, Galaxy S2 with android 4.1.2, all locked to the provider (I know that there is a specific forum for this smartphone and i read some threads).
Now, i want to make it a ROOT and maybe try new ROM's.
Let's start with the questions:
-To make a root, it's better with kernel exchange or with a simple file?
-In the future, if i want to install another ROM, having the root made from the kernel that is with the phone (using a file in the SD Card) may cause some problems? To do this it's better to go to root insecure kernel?
-Why i need to change kernel? which is the benefits?
-It's possible to restore to the previous kernel?
-What are necessary to backup the ROM that actually i have?
-Changing one time the kernel, i can install all the roms i want or i need to install another kernel's?
Thank you for your atention, and one more time, sorry for my english!
@pedrocrv,
Your English is fine! Don't worry about that, man.
Here is my opinion.
Generally speaking, you don't need to replace your kernel. Replacing the kernel can both drastically change your device's performance for the better, as well as render your device completely unusable, which in Android terminology is called "bricked". If your device is "bricked", it is completely useless as an electronic device, making it nothing more than a brick.
But to get back on topic, it's normally only developers like myself who need to replace the kernel, and even then only every once in a while. It's somewhat unsafe for new users, because one little mistake can lead to a huge problem. Trust me, I've seen them here on XDA myself. Don't become one of them.
However, using and flashing ROMs is a whole different story. ROMs normally change aesthetic parts of your device, like the look and features. If you follow the instructions given to install the specific ROM very well, it is practically impossible to brick your device.
If you find a good ROM, go for it. It's almost definitely going to change your device in a very good way.
So to wrap up this post, basically (for you):
Replace the kernel = bad idea, don't do it until you have more experience
Install/flash a ROM = a great idea, go for it if you find a nice one!
The most important thing to remember, however, is to m a k e a b a c k u p. Once you make a backup, you can mod your system however you want without fear of bricking.
Hope this helps.
@thenookieforlife3
Thank you for your explanation!
I understand what you said, but in one thread of my smartphone i see a lot of people talking about rooting their phones but for this is needed to use another kernel.
I want to root my device, and in a near future maybe install one ROM of CyanogenMod (and try others too), but i'm afraid of rooting because that story of changing the device kernel and using Odin... I don't want a brick
Another question:
If i find a file to root my device without Odin, but i don't have the 100% that it's the file indicated for my device, there is some problem if I try to root with that?
And, as i see, there is some diferent files, how i choose one? it's indifferent or one file have specific itens that another don't have?
Thanks a lot!

like Thenookieforlife3 said you do not need a kernel, you dont need one to root or install roms/custom recovery's, they are just for tweaking things or being able to overclock. So, first of all, you are going to have to tell us your model number (or which carrier your phone is on) so we can direct you to the right root guide, s2's are fairly easy to root so dont be scared we will hold your hands the entire way!

We can definitely give you a hand, but we do need a few details to make sure everything works out.
hello again!
@Trozzul and @thenookieforlife3,
Thank you!
So there is the information asked for: (see the attachment for more details)
Bandbase: I9100BULS1
Kernel: 3.0.31-889555 [email protected] #3 SMP PREEMPT Thu Jan 31 14:48:54 KST 2013
Compilation Number: JZO54K.I9100XWLSD
I have another questions to do:
-What vary from file to file on root?
-What is a AOSP ROM? Where I can find a rom that is almost empty of trash, like i think it is a Stock Rom?
-In the information given above, wich is more important to see if I can install that rom? Can I install a rom that is not XWLSD?
Many thanks!
Answers to your questions are in red.
Thank you! You're very welcome!

Compilation Number: JZO54K.I9100XWLSD
I have another questions to do:
-What vary from file to file on root? Normally not much changes from root method to root method - basically, if anything does, it's negligible to you, meaning that it won't really matter. What does matter is that the root method actually roots your phone.
-What is a AOSP ROM? ASOP stands for Android Open Source Project, and it pretty much means that it's a ROM that is as minimalistic and "free of trash", as you say, as you can get it.
-Where I can find a rom that is almost empty of trash, like i think it is a Stock Rom? Here are a few good ones:
AOSP NeatROM for S2
CarbonRom KitKat for S2
SuperNexus for S2
-In the information given above, which is more important to see if I can install that rom? Can I install a rom that is not XWLSD? The ROMs that you can install will be labelled "S2" and "I9100". Don't try to install any other ROMs unless they have those labels.
Hope these help!
I understand what you said!
For example, the AOSP NeatROM have a version that is not AOSP. What it means?
To Install other ROM's i need to root first?
And now, how i simply root by a file?
@pedrocrv,
Answers to your questions in red.
For example, the AOSP NeatROM have a version that is not AOSP. What it means? That means that there is another version of that ROM that is more full of extra features, a.k.a "trash".
To Install other ROM's i need to root first? Yes.
And now, how i simply root by a file? It depends from method to method - some methods are apps that you install and then hit a "big red button", some methods are files that you have to flash through a custom recovery, for example, ClockworkMod. Basically, just read and follow the instructions that come with each root method.
again, thank you!
So, if i find some thread that talk about a file to root, it's just follow the instructions and it's done?
how I know that i need a custom recovery? mine doesn't work?
what is flashing?
Thank you for your attention!
@pedrocrv,
Once again, answers to your questions in red.
So, if i find some thread that talk about a file to root, it's just follow the instructions and it's done? Yes, that's right.
how I know that i need a custom recovery? mine doesn't work? The rooting method will tell you in the instructions whether or not you need a custom recovery, and if it does, it will tell you which one to use and how to use it.
what is flashing? Simply put, flashing is installing a file (normally a .zip) that has been specially formatted via a recovery method (custom or stock).
Thank you for your attention! No problem!

im sure we should introduce him to cyanogenmod, cyanogenmod can be more stock than Asop most of the time, Asops nice but there are most of the time little additions that the creator likes, plus if cyanogenmod installer is compatible for your device he shouldn't have todo much!
@pedrocrv , im not trying to steal his thunder but im trying my best to explain it to you too if he left anything out, otherwise if you guys want me to i will back out .
Custom recovery's are basically a way of getting out of a bad spot and being able to Flash new Roms, if you get stuck in a bootloop (stays stuck at the samsung screen for a very long time, the first time you flash a rom you should let it sit for it can take awhile for the first time you turn it on.) you can most likely get out of the problem and be able to backup your stock firmware if you decide you dont like rooting/custom roms, it does stuff the Stock recovery does not do.
Flashing is basically as thenookieforlife3 said its so you can install Roms, when you hear the term flashing think "installing".
@Trozzul and @thenookieforlife3,
Thank you for both atention! i'm learning a lot of things with both of you!
I know cyanogen, and as i search in the wiki of cyanogen page i think my phone is compatible.
What I need to do with the installer? And if i use the installer, how I backup my actual ROM to future problems or needs to come to origins?
stock ROM-> My actual ROM?
Custom ROM-> a new one
So, if i understand everything:
With my actual recovery i'm not able to install other ROM's. But, with my recovery, i'm able to root my device unless the root method needs a custom recovery and it say's how to install it right?
With the root by my recovery, i'm able to install other ROM's but I will need to further install a custom recovery right?
Many thanks :good:

Yes your stock rom is what the device comes with when you buy it. every device method of being able to get custom roms is different, so when you do get a new phone always do your research, sometimes you can root it and dont need a custom recovery (thats only if you want to stay on stock rom) sometimes you need a custom recovery to get root. with my S2 what i needed todo was get a custom recovery first, installing cyanogenmod already comes rooted so you can make a backup of your stock rom without rooting it.
so i dont also exactly know which device you have, where are you from? it looks spanish in your phones setttings with that screenshot, region is important. is it a GT-i9100 or a GT-i9100b? take out the battery and tell us what the model number says there. this is important for the cyanogenmod installer.

There's very little difference between the i9100 and the i9100b, but the difference is enough that there is a separate CyanogenMod installer for both models.

@thenookieforlife3 i think the cyanogenmod installer installs a CWM right for his question on it? also look at these stated on the Cyanogenmod wiki for the GT-i9100
WARNING:
Some second-generation Samsung Exynos devices are potentially susceptible to a "superbrick" caused by performing a factory reset with the stock kernel, which effectively kills the internal memory in the device. It is highly recommended you do not perform this operation while using a stock kernel for safety reasons. To make sure you aren't running the stock kernel (only needed when coming from the stock ROM), fully install CM without performing a factory reset and reboot to recovery before you perform the factory reset.
WARNING:
If you used a non-official method to remove a provider lock, your /efs partition may become corrupt! It is highly recommended you make a backup of this for safe keeping before attempting to modify your device, especially if you plan to remove such a lock.
WARNING:
The newest Gapps package (20140606) is too big for the /system partition of i9100. Please use the 20140105 package instead. This message will disappear when this is resolved.

Should we tell him to run a benchmark and tell us his CPU?
@pedrocrv (Edit:https://play.google.com/store/apps/details?id=com.antutu.ABenchMark download this app real fast and tell us what CPU you have) so the cyanogenmod installer will be the easiest thing for you, even though installing a custom rom is insanely easy this is basically a one click method, note that all of your data will be deleted so back that up somewhere where you can save it and put it on your phone when its done installing. so as i asked thenookieforlife3i believe that the cyanogenmod installer will also install the latest and best custom recovery for you (CWM: Clockworkmod will be a huge term like CM: Cyanogenmod you will hear a lot, they are both very popular for being the most stable.) it would be stupid enough for it not to install it as well, but if it does not we will show you an easy app that will install a custom recovery, basically one click just like cyanogenmod. now as i looked on the cyanogenmod site, the installer IS compatible with your phone and will install a Stable version of Cyanogenmod 10.2 which is android 4.3. note that the highest right now is CM 11 which is android 4.4.4 kit kat but right now is what we call a "Nightly".
i will try my best to explain this to you, there are four stages that cyanogenmod puts out i will rate them from lowest to highest: "experiments" "snapshot" "nightly" and "Stable", you only need to worry about nightly and stable, Stable is basically the final product the last update for that android version so its the most stable and with less bugs and this is what you want to aim for, Nightlys are Nightly generated updates that update bugs every night asked by people like us to be fixed, Honestly Nightlys are Very stable and are perfectly fine.
Now you might like Cyanogenmod 10.2, personally a lot of my phones run 10.2 if its available, you might like kit kat (Cyanogenmod 11) better instead, honestly try out 10.2 first and if you dont like it, you can update to Cyanogenmod 11 (they push updates out like how samsung would push out updates.) without deleting your information on CM 10.2, im sorry if i confused you at all please ask a lot of questions if needed!

Yes, installing CyanogenMod installs ClockworkMod as the default recovery.

-With CM 10.2, it comes with root, and how to unlock the SIM?
-With CM 10.2, in wich phase of the installation I will be able to backup my stock ROM?
-Imagine that after sometime I want to go back to my stock ROM, What I need to do, because i will have another recovery?

@pedrocrv,
As always, answers to your questions in red.
-With CM 10.2, it comes with root, and how to unlock the SIM? @Trozzul, if you'd please answer this question, that would be great, because I don't know much about SIM unlocking.
-With CM 10.2, in wich phase of the installation I will be able to backup my stock ROM? You will want to make a Nandroid backup before you do anything at all in relation to rooting and CyanogenMod.
-Imagine that after sometime I want to go back to my stock ROM, What I need to do, because i will have another recovery? You will use either the "Install update from SD card" or the "Install .zip from SD card" feature. I don't know exactly, but if that time comes, please let me know and I'll do the research necessary to help you out.
-WIth the CM 10.2 I will have my RAM memory more free? It all depends on what apps you have running at one time. I personally use Advanced Task Killer Free to kill apps directly after I'm finished using them, and that frees up a lot of RAM. CM probably overall will make your RAM memory less free, but if you use the app killing trick, you won't ever have a problem with it.
In the attachment are the images of the test Great, thank you for doing that.
Hi all,
Can I replace the ROM of my phone to earlier versions?
The manufactures have done a mod of JB 4.2 to 4.4 KitKat but the ROM have a lot of bugs, sad , my question is, can I flash a 4.2.x stable ROM from for example a S4 clone ROM? Plus, my download mode is fake because everything is chinese.
And also, with the attachments and using CPU-Z.

Hi.
Unfortunately I was unable to find any support or info about your device on xda. If you have the stock firmware or a nandroid backup, you could restore the old ROM.
You can also try a factory reset and set up your phone again to see if that sorts things out.
Another possibility is to root your device, install Titanium Backup app and freeze/uninstall bloatware to reduce burden on phone resources. This might (or might not) reduce your lag. Please proceed with caution and only if you know what you're doing as injudicious use of this feature can cause system instability.
Short of that, I'm afraid your only option is to contact the manufacturer and request for a downgrade.

I couldn't find any ROM or support for your device on XDA. There are a few random threads lik this one :http://forum.xda-developers.com/android/help/question-alps-s5-clone-sm-g900h-cwm-rom-t2806419 but no proper custom ROM.
