Hello Everyone,
I am not new to android as I have had multiple android devices, however I purchased a SGS II from a friend and he rooted it. However, he does not remember what software he used to root it. So I used the one click method and it said it unrooted it no problem, however superuser and CWM is still installed and JD plus says it has root access. The kernel is XXKG3 and I installed and used it no problem. However, again when I go to CWM under current kernel: unknown. I tried everything I can think of, searched these forums the best I can and I still need help. Can anyone help me? If so, greatly appreciated.
Thank you for all your time
Have you tried flashing another kernel like siyah?
How will using that kernel help? Just out of curosity, I dont know too much
You have not searched properly. All you had to do was use the search button use a few keywords and boom you have the results. But anyway here i go.
To root go into Chainfires thread that is in the original development and look for cf-root kernels. Flash that through odin and it gives you root and cwm recovery and manager. Once you have done that it basically roots your phone. Now if you want to unroot all you have to do is flash official firmware from Intratechs thread again in original development section and your phone will be unrooted..Guides on how to do that are in both threads and at the first page. Now this is were you come in
Read read read...read the information given in those threads and you should understand more and you should be fine. good luck
I did do my research, I must have missed them. I will be trying this tomorrow, thank you!!!
Just flash a stock rom and then flash cf-root kernel mate..

I dont have a computer. is there a way to root without it? My firmware is 2.3.4 and its kernrl is ki2. Thanks
I saw a thread a while ago, I can't find it now so you're gonna need to search, but you just put an update.zip in your sd, flash it in stock recovery, and viola - you have CWM (be sure to download a rooted kernel). Good luck.
If anyone knows of the thread please post links

Zips flashed with e3 needs to be signed and I think siyah is signed unlike many other roms and kernels so flash siyah and reboot to recovery recovery to flash anything, if you want to keep you current rom, I think downloading superuser is enough

zaheedahmed,
Yes it works on ICS not GB Since devices come with GB then they'd have to use ODIN to flash ICS
Anyway thread closed since been asked over and over!
Use the search before posting there is even implementation when posting to see threads similar too............
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

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........

Yeah no problem. I would suggest that you wait a while before doing this. Read through all the stickies and guides to can find, and get more familiar with everything. Then after a couple days, go for it.

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.

I am using a Samsung Galaxy S3 i9300 which is rooted from CF-Root 6.4 (http://forum.xda-developers.com/showthread.php?t=1695238) and I have some questions before I flash my first custom ROM. I have researched these questions on Google, YouTube and through all these threads and I cannot find any answers. Therefore any help on these would be much appreciated.
1) Do I need to update my CWM Recovery to the newest version before I flash Jellybam 8.3.0? (P.S. the CF-Root thread states "Not compatible with ROM Manager ! Use the CWM Manager provided instead (installed by CF-Root automatically)" I assume this means I cannot update CWM Recovery through ROM Manager.
2) Will flashing this ROM remove my root privileges? Will I have to re-root through Odin again?
3) Do I have to use Triangle Away if I manage to successfully flash Jellybam ROM? This is because I heard resetting your flash counter is dangerous.
4) Do I need to have BusyBox installed? Tried to research this and I do not understand what this does.
5) Are there any other precautions to take bearing in mind this is going to be my first flashing of a custom ROM?
Any help on these questions would be much, much appreciated. Sorry in advance if I've posted this in the wrong section or I've broke any other XDA rules. Also, apologies if you're offended by how much of a noob I am. Thanks.

1 please don't bother with rom manager but you need latest cwm anyway (or better yet, philz advanced cwm in my signature) to be sds safe
2 root is in the rom. When you flash a rom, the entire rom is replaced - root files included. However, custom roms are all rooted anyway so you'd be replacing the root with root.
Please note, jellybam discussion is banned on xda
3 its not really dangerous. It needs to be done before returning it to stock
4 many root apps use busybox to function. Most custom roms have busybox anyway
5 read, read, read. Read all the stickies and guides in general. Read them twice. Before doing anything you don't understand, search. If you can't find, ask. Its easier to teach knowledge than to fox broken phones

Thanks so much for this reply. Just need some clarification on some points if you don't mind.
1) How should I go about updating my CWM Recovery? What's the best and safest method?
2) What is SDS?
3) If it isn't an issue, could you tell me why Jellybam discussion is banned on XDA?
So grateful for this invaluable info. Thanks a lot!
1. Like rootSU allready suggested, use PhilZ Recovery. Visit http://forum.xda-developers.com/showthread.php?t=2002953 and read the first and second post. These explain step by step how to do it.
2. SDS stands for Sudden Death Syndrom. For more information on this topic visit this thread http://forum.xda-developers.com/showthread.php?t=1993044
There you can also check if your phone could be affected.
3. Sorry bro, can't help you on that one since I don't know myself.
As for 3 jellybam, I didn't see it myself - but apparently the developer used the work of others without credit. I read, passing it as his own work. I wasn't here so I can't say anything more than that

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?

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.
Sent from my GT-I9300 using Tapatalk
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:

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
