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........

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 just picked up a i717 and I'm trying to root via this guide http://forum.xda-developers.com/showthread.php?t=1740367. I first tried to flash CWM with odin and then I tried a root file with odin then TWRP with odin but after all of them I still cannot get into recovery (it's still stock recovery). Any help would be appreciated.
Read through THIS THREAD.
I had issues when trying to root my Bell i717 as well. All the links to everything you need should be in there...just read...and read again.
in case you miss it or read too fast..
there is a point where you pull the battery so you dont have your recovery overwritten during boot..
once i was in cwm recovery i flashed a custom rom that did not have that "feature"

It all depends what you are looking for.
I want something I can record calls with, and something not bloated.. so I'm still searching for just the right Rom. I used to use wanam on the sgs2 and he spoiled me for all other developers.

Just got my note. Previously had the gnex. I have always used aokp. I plan to install it on this phone once i can get root lol.

I have the Rogers note and running ICS BlackStar X as my daily driver without any issues. Been hearing good things about the Novena rom but haven't tried it out since I'm happy with my current setup.
I'm not new to rooting or installing custom roms but my note has me stumped. I followed all the guidelines with rooting and after flashing a new kernal through odin my phone would be stuck at the samsung splash screen. Figuring I bricked It I flashed the stock one and now my phone wont get past the Telus splash screen.
Did I cook this phone? I had no issues with my S and S2 before this I cant figure it out.

okay so I read through some of the threads and I still don't know how to fix my issue. I rooted my phone using Odin v 1.85 and used siyah 3.4.2. I did it successfully and everything was good. I then gave the phone to my cousin and he said he performed a factory reset to get rid of everything on the phone ( contacts ,etc). Now when I turn on the phone it shows the samsung galaxy display with the triangle and then the screen goes black and just blinks. It still goes back into download mode I just dont know what to do to fix the problem. I know I'm a noob but please HELP!!!
Development section. You'll find the stickies that show how to flash stock packages with Odin. Go back to stock to fix your issue. You should then be able to load a new kernel and flash a custom rom.
Oh, and never let that cousin touch the phone again.

You will need to root first. If you did not flash the stock plus root package already, flash that, and then install a custom kernel which has ClockworkMod Recovery. Then you can flash any firmware.
There is a good guide linked in my signature.

I'm going to install Mobile Odin lite, I already found the flash kernel for the I-777. After installing both of these I should be good to flash the ROM of my choice by just putting the rom on the sd card right?

Flash a kernel with ClockworkMod Recovery, then boot into recovery and flash the firmware. Mobile Odin can't handle the CWM flashable zip format.
There is a Siyah kernel for gingerbread that would give you CWM so you could then flash a custom rom. It would be in the development section. Just make sure you grab the version for gingerbread and not ics

I assume you mean nandroid backup from ClockworkMod Recovery? No. It's mainly a space issue, where you want to store them, because they take up quite a bit of space, especially if you have several.

Depends on which OS version firmware you want.
I like Eclair and Froyo
Okay so here's the low down. I recently rooted my sprint note 3 via CF auto root method. Shortly after I experienced random reboots. I found out through system tuner app that only one core was online. So I ticked "Force all cores online on boot complete", which seemed to fix the problem. Now, whenever I play games I set cpu governor to performance and OC to like 2.7something.. But halfway through my gamei realize the cpu gets set back down to a lower frequency. Also experiencing lag in games (which IMHO should not be there.). Does anyone have any ideas as to what may be causing this problem?Any help is greatly appreciated.

I would try going back to stock, that's usually what I start with.

How would I go about that. I'm new to rooting so I apologize. But I have one backup from when I was freshly stock but rooted. Or do I need to do a full unroot/ factory reset? If so how?
To go back to stock rom easiest way would be via odin. U will need
1.odin software.
2.usb driver
3.stock rom files (modem, pda, csc files)
Do say if you need more detailed instructions.
I would appreciate it. I have Odin and the USB drivers already.
Ok so u just need stock files to flash..
. And the problem is?
Is that mj4.tar? I need a step by step. Odin tar then what?
