This may be a really stupid question but I'm still learning
So after soft bricking my phone once today already I have now backed everything up so I don't have to redo everything when I undoubtedly mess something up again
I'm trying to overclock my s3 but I know I can't do this on the stock kernels, do I need to install a whole custom Rom or can I just use a custom kernel. If so how would I do this? Thanks

Hi, firstly if I was you I would read all of this: http://forum.xda-developers.com/showthread.php?t=1827635. This will explain about the dangers etc of overclocking on our specific device. Then, do you have a custom recovery installed? Like CWM? If you do and if you understand all the risks associated with overclocking, then you would look here: http://forum.xda-developers.com/showthread.php?t=1709686 This is siyha kernel, I trust this developer a lot, I have used his kernels ever since he first released one for the galaxy s2 a couple of years ago. You should read the full OP, and if you feel you are ready you just download the appropriate kernel zip, as in make sure it is for the galaxy s3. Also, make sure you flash the right kernel for your android version, like an ICS kernel will not work with a Jelly Bean rom and the other way round. Then simply flash it in Clockworkmod recovery and slowly and safely play around. I can't stress this enough, only play around with things after you fully understand what it is and does as overclocking can cause hardware damage. I hope this helps you

you can either install a custom rom or just root your stock kernel. I tried siyah kernel before, it support overclocking and dualboot.

Just moved from iPhone to i777, wanted to get ICS, but eneded up bricking my first phone by installing something meant for i9000. At that time I didn’t know Galaxy S2 has variants, just searched for S2 and got burned. My fault…..should have understood better.
I want to do it right this time so I have been reading about i777, ROMs, kernels, CWM.
I want to put SHOStock or CM9 ROM.
I know where these ROMs are and how to flash them using CWM.
But that’s where my confusion starts, that there are just too many sources and options and I don’t know which one is right.
So please advise.
How do I root?
Using this? It has multiple options
http://forum.xda-developers.com/showthread.php?p=18576627#post18576627
or this ?
http://galaxys2root.com/galaxy-s2-root/how-to-root-att-galaxy-s2-sgh-i777/
Which kernel to use
The one mentioned in SHOStock thread #3 post the Cherry Picker Kernel for i777 or Entorpy? Siayh
How do I get CWM on these, isn’t recovery part of the kernel or do I flash It separately or may be use ROM Manager, once rooted.
Modem? What does it do? Is it for phone or wi-fi and how do I know which one to use.
My phone’s data
SGH-i777
Android 2.3.6
Baseband I777UCKK6
Kernel 2.6.35.7
Build#
GINGERBREAD.UCKK6
Here's what you need to do:
1. Use Odin to flash stock UCKH7 with Root, available here. Be aware that doing this will require a full wipe, so do what you can to back up your sms/mms/contacts and other data. READ EVERY STEP CAREFULLY. Do not flash a kernel with Odin.
2. Now that you have root access, download Mobile Odin from the Play Store. Use it to flash either Entropy's DD or Siyah. This will install CWM Recovery.
3. Boot into CWM Recovery and make a nandroid backup.
4. Use CWM to flash SHOStock or CM9.
First of all thanks for responding.......
Is there a relation between which ROM will work with which Kernel, I may be wrong but I got the impression, depending on which ROM you are putting, you should have a kernel that supports it.
Also it seems like, ShoStock has its own variation of entropy, named cherry picker.
Thanks.......

Sometimes there is, but it seems like most of the ICS kernels are interchangeable. Just try out each kernel for a few days...once you have CWM, switching kernels is no big deal. When switching kernels, though, it's always wise to flash jivy's Kernel Cleaning Script just before flashing a new kernel.
Can you use CWM to flash kernels as well ? I thought they always have to be done using ODIN.
May be I underestimated CWM, I thought it was for ROMs and zips only.

u can use mobile odin or cwm but its just a matter of preference you just had to use mobile odin at first to acquire a cwm enabled kernel but pretty much you can flash everything in cwm as long as its specified to be cwm flashable zip kernels roms and modems and such
edit: the free mobile odin only lets you flash kernels btw its the premium version that lets you do everything without going to recovery
hope to help

You don't seem to have a firm grasp on all this. Maybe you should do some more reading before going further...
Anyway, here's a brief explanation:
A kernel is the underlying core of the operating system; it is how the OS interacts with the hardware.
A rom (the proper term is actually firmware, but nobody uses it) is basically the whole user interface; it's the part of the OS you see. When you flash a rom, you're flashing everything, including a kernel.
Like I said before, you never want to flash a custom kernel using Odin. Doing so will trip the phone's flash counter, and this will show up if you ever have to take the phone in for warranty stuff.
The reason it's ok to use Odin to flash the stock with root package is that it comes with the stock kernel, not a custom one. Basically, once you're rooted, you shouldn't touch Odin again unless its to recover from a brick. Basically everything else can be done in CWM.
Yes I am still reading & trying to get a grip on it.
So first I will root it, then flash kernel using Mobil Odin
Then get in CWM mode ad flash ROM, which will come with the kernel i.e. cherrypicker kernel and modem I need.
Yes one part I have understood very well is that use CWM as much as one can to avoid committing mistakes by flashing something that doesn't belong.
Sorry for asking so many qs., I wish I could understand this faster.....
Thanks again........

You don't need any more of a guide than that. Don't worry about breaking wifi, that isn't a problem on any of the popular roms.
If you want a Samsung based ICS rom that works really well, I suggest ShoStock2. If you want an AOSP based rom, most people suggest AOKP. I haven't tried it personally.

Ok I am really confused about this. So I just rooted my new Galaxy S II I got (the CF method using ODIN) and I was considering installing Cyanogenmod. However I changed my mind when I decided I could put a kernel on the stock instead. Now when I read thread for the kernel (as well as going to the website) it says it includes CWM touch Recovery with gesture support. Now does this mean when I flash the kernel with the recovery I got from rooting, it will also flash over the current recovery to the touch one? If I get OTA updates and apply them, will it remove the kernel and my root access? Also I am wondering has anyone had problems with this kernel?
Thanks for all the help.
Ainslie.
1) If you flash Siyah, it will overwrite/replace the current version of recovery you have, yes.
2) If you flash any stock firmware (including OTA updates), yes, of course you'll lose root. Any update will have a new stock kernel which will replace your existing kernel. If you do an update, you'll need to re-root your phone.
3) I've been using Siyah since about the 2nd week I got my phone (>8 mths) both Gingerbread & ICS and I've never had any major problems with it.
In saying that, obviously your experience with a given rom or kernel will not be exactly the same as someone else, because everyone has their phone setup differently/uses it differently.
So do a Nandroid backup in CWRecovery before you try Siyah, and if you don't like it, restore your backup. If you're going to use Siyah, I very much recommend you read the dev & discussion threads (certainly since Gokhan has been doing ICS builds at least). Any questions once you've installed it/started using it, ask them in the discussion thread (not the dev thread).
Ah cool thanks.
Also just one more questions.
When the new recovery is flashed with the ROM will the CF-ROOT custom CWM app work with it? Or will I have to download ClockworkMod from the Play Store?

Hi,
When u install siyah kernel, it includes the cwm app with the kernel. And the app is the same app you get in the cf- root kernel.
Siyah kernel is by far superior to cf-root. If you set it up right, you can get much better battery life. And it is so smooth. I would recommend that u use siyah..

I am far from giving up but this has caused me so much headache and I've never bricked a phone as much as I've done this. Needless to say, I've learned a lot but I have yet to figure it out.

Assuming your phone is in fully working condition, then there is evidently something you are missing in your understanding of how the phone works. The SGH-I777 is different in that the recovery is built in to the kernel, and *not* installed separately in it's own partition. From reading the above, I'm wondering if your are trying to install a separate recovery, or if you art trying to install ClockworkMod from the play store by installing Rom Manager?
To help you get through this, I need to know exactly what you are doing that is not working for you, in a step by step explanation.
Thank you for your reply. I had feared this was a dead thread.
I am aware that custom recovery is embedded in the kernels themselves and not a standalone as I have encountered with my Hercules.
As for what I have tried. From manager from play store will flash 100% but never give me a complete notice which, I believe, is a successful download but not flash.
As far as kernels are concerned. I have used ones that are compatable with stock rooms. I've tried a couple that don't. All have failed to yield me with my desired result.
Is there a piece of code that I can modify to get the kernel embeded recovery to kill stock Sammy?

All custom kernels built for the I777 come with a recovery either based on CWM recovery or TWRP recovery. These kernels are usually compatible with the stock system which matches their version number. Once you install the custom kernel to replace the stock kernel, you will be able to enter recovery and it will be CWM (or TWRP in a few cases).
For Gingerbread, you can do this without rooting the device, since there is a Siyah kernel for Gingerbread that is available in tar format that can be flashed with Odin. To do this, flash the I777UCKH7 full distribution, which you can download from the Download Repository (see the link in my signature), then flash the tar version of Siyah 2.6.14 Kernel. Flash each one in PDA. Without ticking Re-Partitioning. You will now be able to boot into recovery and you will have CWM recovery where you can flash many types of custom firmware.
Another route you could take is to flash the I777UCMD8 full distribution from the Download Repository, then use the Framaroot app with the Aragorn exploit to root the device, and then use Mobile Odin Pro, or Mobile Odin lite to flash the AJK v4.9 NoSwap kernel which is compatible with the stock system. If you need additional instructions on how to do that, just ask.

But after the phone being rebooted, I still had the stock kernel.

Well, I don't really know either of them, I don't mind stock, but I want to change things, sometimes it just isn't up for the task, or uses up battery when I would rather it didn't, without even knowing what they do, and looking around, I found the perseus kernel, I would like some opinions on the kernel, I would be very grateful if you told me if it fits me, if it's compatible with ParanoidAndroid, and finally if you have a better suggestion for a kernel.

Guys I know this is long but PLEASE don't freak out! I really need some advice from you experts on this! I hope you could spend your time reading everything here and give me some advices! Thanks!
Phone details:
Model number: GT-I9300
Android version: 4.3
Baseband version: I9300DXUGNB1
Build number: JSS15J.I9300XXUGNA5
Hello guys, since I'm not really a rooting expert (previously I rooted a motorola device), I would like to ask for some advices regarding rooting our S3 because I have only one phone and I can't afford to brick it.
1. So basically I'm referring to the guide here. However, that rooting guide is for Samsung Galaxy S3 on I9300XXUGNA7 Android 4.3 Jelly Bean, which is different from my build number (I've checked software update on my device over OTA and Kies3 but it says I have the latest firmware), will it works for my phone? Also in the guide it says to use odin3 v3.09, however in CF_auto_root page here it says to use odin3 v1.85, so which one is working for my device or which one is better?
2. Next I would like to ask is it necessary to install CWM recovery to replace the stock one? After searching around, I found that there are some people who installed CWM recovery even before rooting, is that even possible? So basically to install CMW recovery I think I will follow the steps here, is this working for my device?
3. Okay I know this is the dumbest question... but is there anything else I need to do after the above 2 steps (flashing kernel, modem etc.)?
Thank you very much for spending your time reading my post. I hope you can clear those doubts for me!

Flashing your phone in any way doesn't guarantee not bricking it, see this thread
Scroll down to the quoted section headed Quick Root from there
Download Odin
Download CF-AutoRoot for your phone
Read the link on rooting
It is really straight forward just read up on it but don't read too much into it a frighten yourself

Great that thread helps a lot! I cleared most of my doubts now, but one more question please, after rooting, I wished to install ported apps like S5 launcher and accuweather, and in order to install these I need to flash from recovery. Is it possible to flash this using stock recovery? Or I need to install custom recovery like CMW?
You can't install anything with stock recovery, you'll need a custom recovery.
Make sure you have a full nandroid and efs backup before you flash anything -ported apps can break the framework and produce bootloops.
Seriously though, all this information is available in the sticky or by searching -why do need people to write it all out for you?

Thanks for your information. I did search around and try to understand the things myself, but still there are some doubts remain, that's why I opened this thread hoping that someone can clear the doubts for me. This is my only phone and I really can't afford another (I'm from a low-income family), I just want to make sure everything is alright so that I don't mess up my device. Thanks for your understanding
If this is relevant for Samsung galaxy s3, I got this done the other day using Odin to unlock and root, ran the root app to confirm root. The ROM manager to found CWM recovery flash. So far all good, should take 5 mins in all but an hour in prep and homework.

Don't use rom manager, it can soft brick your phone.

Hello! I agree that it would be better NOT to use Rom Manager. Many users had problems because of it. The safest way, in my opinion, is to flash a custom kernel using Odin. For example, I had stock rom and used Odin to flash boeffla kernel (not advertising it, just saying what I did) because that kernel had both a .tar version and a .zip one. I downloaded the .tar version and flashed it with Odin by putting the .tar file in the PDA column. That's for root.
For recovery I'm using PhilZTouch and I love it. It supports both JB and KK roms and that is preety cool. Also it's full touch so I don't need to stress my hardware buttons. It's also available as .tar file so you can flash it with Odin just like the kernel.
That's how I'd recommend anyone to root and install a custom recovery on a Sammy phone because I believe it's the safest way. PS: before launching Odin make sure the phone is NOT connected to the PC and that Kies isn't running in the background (use Task Manager to check) Goodluck! !! :thumbup::thumbup:

Wow, that's great. By saying unlock, do you mean unlock the bootloader? Wait, is the bootloader locked in our S3?

Thanks! Will check out PhilZTouch recovery :fingers-crossed:
Currently struggling with deodexing/odexing the stock rom, after reading around I can differentiate between the odex and deodex rom, still digging on how to deodex a rom though (since I want to install some S5 mods). After searching around, it seems like titanium backup can do the deodexing/odexing just nice Gonna do some more preparation, hopefully I can have my device rooted by this week
You could flash PhilZ Recovery and make a nand backup of your rom. This way you'd have an emergency copy if something goes wrong or if you break something in the system. Just my thought
