Hi!
I'm a total noob. This is my first android phone. I've read everything about rooting, and I'd like to install a custom rom, but I'd like to save the stock rom/kernel first. I've found this topic: http://forum.xda-developers.com/showthread.php?t=1075278
I don't really know if these are what I need. Also, I have an xwkf3 device, but it's slightly branded for hungarian T-mobile (the browser has a different name and icon, and it also had every network setting by default).
So, basically I either need someone to tell me which one to download, or better yet, how to create a backup of the whole thing.
Yet again, I'm sorry for asking something probably really stupid. I've tried to google it many times, but I failed to find an answer. Thanks for everyone in advance.
Are you rooted already? If so just boot into ClockworkMod recovery (cwm) and then navigate to backup. (navigate using volume buttons and use home to select)

Here is the kernel rooting thread.
http://forum.xda-developers.com/showthread.php?t=1103399
Dial *#1234# into the phone dialer to find out what firmware you have installed.
Root using chainfires method and make a full backup via CWM.
Flash away. But make sure the Rom/firmware is for your device. Eg i9100 international.
Good luck.

I'm not rooted yet. If I understood everything correctly, the safe kernel is the same for branded/unbranded devices, and only the rom is different?
I'm currently downloading both secure and insecure kernels. After rooting, can I revert back to the secure one to install custom roms?
BTW, thank you for your quick answer

I'm not positive but I think if you are rooted and install a stock kernel (without root) you will lose root and won't be able to flash custom roms or make Backups. Its really easy to root, just find the appropriate insecure kernel, flash it with Odin, make backup, and then try new roms!

Don't flash back to stock kernel.
Use a jig if you want to get rid of the yellow triangle.
Edit: after flashing one of the cfroot kernels make sure you can get into CWM recovery mode. Vol up+power+home
If you can then you're ok to follow the instructions of the Rom you want to flash.

Thank you. One last question, if I may. Some of the roms I'd try use different kernels, then mine. If I install one of those, and want to revert the phone to factory rom, and kernel, should I root it again with an insecure kernel according to the rom, or one according to my device's current, factory rom?
You will probably find that the Rom kernel will be rooted and have CWM. Just check in the 1st post or 2 of the roms thread.
If you use CWM and make a backup of your stock Rom, after you root now but before you flash any other Rom, you can restore with CWM to get back to stock firmware.

To fully return to stock you have to flash a stock rom and stock kernel from Odin. The rom that you want to back up will be a stock rom but it will be rooted because of the rooted kernel. So yea, flashing stock firmware and kernel is the only way to get back to fully stock.

But if I restore my backup rom, and flash it with an original kernel, it would be unrooted, and basically the phoen would be just as it is right now. Is that right?

Hi I'm new to using Samsung phones, always had Moto. Is Entropys ZombieAss kernel the only kernel that I can flash ICS(new official ICS ROM ect.) roms on with CWM, or are there more? I'm unrooted on stock 2.3.4, any help would be appreciated, thanks.

You can flash almost any ROM with almost any kernel, but ZombieAss will boot and run recent i9100 based ROMs. As in, you can't use ZombieAss with the official ICS ROMs from AT&T. If you're on stock 2.3.4, you can go ahead and flash any ICS ROM from their threads as long as it's for our phone -- the i777. They should automagically flash an ICS kernel.
In short, use ICS kernels with ICS roms, Gingerbread kernels with Gingerbread roms, but any kernel with CWM can flash anything without trouble.
Just pick your ROM and go in my opinion! pretty much all of the ICS ROMs include a kernel that will include CWM. (exception being the ATT leaks, but i believe even the one built by Task650 includes a kernel with CWM)
Kernel for ICS ROMs
I use overclocked kernels by SebastianFM on Android Revolution HD ROMs. Combination of the two works best for me.
You can also check out faux123's released kernels. Also very nice work (with ZRAM)

Think you might be lost .. Everything you referenced was for the HTC Sensation.
To the OP,, do not flash sensation things! I'd assume they'd fail to install anyways,, but if they didn't,, you might be in for fun!
Yeah man, I'm on HTC. That's what happens when you're a noob.
Didn't even think about ALL OTHER DEVICES.

Just to be sure though, first I have to flash a kernel with Odin that has CWM, then flash a ROM directly from internal/external sd? Or. Can I just flash a any ROM with Odin? . Just don't want to mess up and have to use the return to stock method. Thanks

Once you have CWM (any CWM), you can go pretty much anywhere without returning to stock.
People that complain about bootloops didn't know the most basic rule of flashing:
ALWAYS WIPE DATA IN CWM WHEN SWITCHING FIRMWARES! (usually no wiping needed when switching kernels though.)
Suggested order, in my opinion:
Flash a Gingerbread kernel with CWM, such as my Daily Driver for Gingerbread
Do a Nandroid backup of your current setup (Backup and Restore in CWM) - Enter CWM using the three-finger combo, NOT via ROM Manager
Once you've done a backup - flash something. If it's in these forums, it should be safe. I suggest reading the threads for various releases to get a feel for things. Don't ask what's best - that is a matter of taste.

DON'T use Odin from your computer! Using Odin trips the flash counter and that'll probably give you headaches later. Use Mobile Odin instead, you can find it here under Step 3a, it allows you to flash zip files (lite version is free, allows you to flash only kernels from the phone itself)

Read same thread. Steps 2a-d detail four different ways to root. I think you would do well to read the thread's OP in it's entirety a few times before you try anything.

There is one tar ball available for Entropy's daily driver kernel. It's the top one in the list of downloads, named DD_01232012.tar. If you flash it, you will increment the flash counter and invoke the yellow warning triangle on boot, but you can reset the flash counter and remove the yellow triangle with a usb jig, or if you install ICS on the phone, you can get the same result using chainfire's Triangle Away application. And by all means, read the full OP of my guides, and any other follow up information you can find, so that you will have a solid foundation for making decisions as you go forward.

Right now only my Gingerbread kernels have a .tar download available.
It is my opinion that no one should be going straight to ICS yet without already having some experience with kernel flashing/installing CWM/nandroiding their current Gingerbread firmware as a backup/properly testing custom firmwares, which is why only my Gingerbread kernels have .tar files. ICS on our devices is still too new.

Triangle Away will reset that on ICS.
Entropy, I've been wondering. Does your ZA Kernel work on the AOKP roms that Task has been porting over to our phones?
i dont think ZombieAss will work with non-Sammy based ROMs, but I haven't tried it

Thanks for all the help. I actually downloaded mobile odin, then used doomlords easy rooting tool, then flashed, I forgot the name but it was something like "one kernel to rule the all", flashed with mobile odin, and got CWM, then installed you current daily driver, made a Nandroid backup, and now I'm ready to flash. I had one more question, what is the difference between the regular Nandroid backup and the advanced? And should I be backing up regular, or the advanced way?

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

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.

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?

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

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

Download Siyah kernel, the latest 1.7rc then flash it using Odin. Then you're good to go. Just read in general section. There's a guide by bala on how to OC/UV.

Before I go into flashing kernel I have a question to ask. Which kernel that is compatible to the att 4.0.4? Just want to make sure before I flash it through Odin Mobile Lite.

Are you wanting a kernel to use in place of the stock one for everyday use? Or are you wanting a kernel with CWM to flash a new ROM?

With CWM to flash a new ROM that also compatible for stock one. If any.

Your best bet is the Siyah kernel.

You should be able to flash this zip in mobile Odin.

Thanks. I'll try it.

I just noticed you said lite. Lite won't flash the zip. You will need to unzip the zimage file first.

help please
I have an i777 that absolutely refuses to allow CWM. I have tried Siyah kernel on both GB and ICS stock roms, as well as AJK kernel on JB stock from. 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. If anyone could offer some advice or things to try I certainly would appreciate it.
I am currently running stock 4.0.3 with Siyah 4.3.3 kernel.

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?

The phone is pretty old, and not many people hang out here any more. I still check in every once in a while. You would get more attention in any forum if you post a new thread with your question, rather than necro-ing an old thread.

I assume you meant to type "Rom" manager? Rom manager should not be used on the I777. For reference, see the very top sticky thread in the Q&A forum (this forum) [A] Rom Manager ******WARNING READ THIS BEFORE******

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.
Is there a piece of code that I can modify to get the kernel embeded recovery to kill stock Sammy?
