Hey. So, I bought the Samsung galaxy s2 with bell as soon as it was released (august 2011) and i expected there to be potential updates along the way, since it came stocked with android 2.3.3.
HOWEVER, bell, being its lazy self, haven't pushed the official updates for its i9100M modeled gs2. And I've gotten really bored with the TouchWiz UI, and was wondering how i would go about installing CyanogenMod's CM9 ICS on my UNROOTED STOCK Galaxy s2.
Phone information:
Model: GT-i9100M ( android 2.3.3) (un-rooted)
Kernel version: 2.6.35.7-I9100MUGKG2-CL371789
Build number: GINGERBREAD.UGKG2
Any help would be much appreciated. thank you
Go search on google or here in the forums how to root the gs2 and install a custom recovery. Then go and flash the recovery and go to the CM9 link and download it and put it in your sd card. Then you can reboot into recovery by pressing volume up, home and power. Then follow the guide posted in the CM9 post by wiping data, etc. let the rom boot up and you've got cm9! I have a bell gs2 unlocked on Rogers running cm9 so feel free to ask me questions haha

Heyy, thank you I thought that this might be what i would have to do lol
So um, another question.
should I use this file over here (http://forum.xda-developers.com/showthread.php?t=1531222&) the 1.51 v?
And could you please link me the correct link on CM9's post on how i would install it?
Also, would you recommend that i flash it with this rom?
Cm9 is here http://get.cm/?device=galaxys2 grab the latest one at the top.
As for installing you'll find plenty of faq's in this forum, look around, read and read some more.

Thank you once again
is it a stable build?
did you find anything wrong with it?
Could anyone also help me out with a Step-by-Step process on how to install CM9's ICS from my STOCK unrooted Galaxy S2.
I'm really new to this whole custom roms world, and I'm not exactly sure how everything is supposed to work out. But i'm very willing to give it a go
Thank you
diaperboy, did you update your gt-i9100m? I will try to do that (update to a custom rom), but I'm not sure if it will work out.

Although i did successfully manage to install CM9 onto my device
It was very simple.
If you'd like i can guide you through the process
Ok. Here is it. I have seen a stable build of Galaxy S2 GT-I9100G, REMEMBER IS (G)!!!! Don't reply me with the answer of S2 without the G, I'm asking the[G] Version. So the stable build was here http://download.cyanogenmod.com/?device=i9100g&type=stable for the [Direct Download: cm-9.1.0-i9100g.zip ] So i wondering if it really stable and safe. So, here the Question.
1ST:Is it safe to flash? Will it brick? Worth it? And what Android version IS IT?
2ND:Is this CWM Good, Working, and Safe to flash?So, i'm giving 2 link, (Not downloaded from here)=http://forum.xda-developers.com/showthread.php?t=1631934( and i found these word=This is a kernel including ClockworkMod Recovery for use on Samsung roms.
Don't use this kernel on aosp based roms like CyanogenMod!!!) And this link is where i'm downloaded the CWM and flashed it, http://forum.xda-developers.com/showthread.php?t=1683800( because of GT-I9100G_LP7_ClockworkMod-Recovery_5.5.0.4 it make me think it is the same from the first link i gave that have LP7 hacked, and i wonder it will it be also not support cynogenmod.
3RD: If the CWM at STEP 2 is not supported, What CWM that is work for SAMSUNG GALAXY S2 GT-I9100G and Flash able to cynogenmod with not PROBLEM!
4ST: Anyone have this on their Galaxy S2 GT-I9100G? Is everything WORKING FINE? Is the Performance and Battery Good?
5ST: Do i need to factory reset the phone before and after? And can anyone tell me the step if you can?
My phone is rooted and my battery is so bad :crying:and i wonder is this rom good for battery and performance. I'm afraid of bricking my phone because of the CWM. I installed cwm on galaxy 5 and it died.:crying: So This is important information to me. and PLEASE ANSWER ALL MY QUESTION CAREFULLY!

Alright, ill post this is Q&A forum that you said.
1. Yes, it is safe. And CM9 is Android 4.0.4
2. If you want CWM I suggest you to flash Horsepower kernel
3. CWM5/6
4. AFAIK, everything works
5. Only before changing the ROM.
hmm

I couldn't find an answer on the threads. I rooted my at&t last night w entropy512s one click kernel and root. Well I'm new to the phone tech so it took me a while. I now cannot use any of the market Hotspot apps to run my tablet off my s2 wifi. I could before the root and from what I was told it should be easier to do this after rooting. Am I missing something? Is there a special way I have to do it now? I'm so confused.
Sent from a still, small voice with help from my Galaxy s2.
I'm not familiar with those applications. I don't know any reason they would not work. And it's not clear from your post what exactly the problem is. You mean you can't install them, or that they do not produce a wifi signal even though installed?
Anyway, almost all custom roms include portable wi-fi hotspot, as well as usb tethering and sometimes bluetooth tethering. Since you have rooted, why don't you go ahead and pick a custom rom and put that on. Problem solved.
There is a good guide linked in my signature.
Yeah, once you have a custom rom, just use the built-in tethering. Works great for tablets.
Yea I can install them, I've tried a few of them and none put out a wifi signal. I don't know what rom I should flash yet. Since I did the entropy512s one click root+ kernel I understand that the kernel is gingerbread, does that mean I need a gingerbread rom? I was hoping for the latest, greatest build. Any guidance is GREATLY appreciated as it took me hour just to root. Lol

Since you used Entropy512's package to root, you have a stock kernel. In order to install custom firmware, you need to first install a custom kernel that contains ClockworkMod Recovery onto your phone. That kernel must be Gingerbread. However, once you have the kernel and CWM installed, you can then flash any firmware you choose, Gingerbread, ICS or JB.
The guide which is the first link in my signature contains all the info you need.
Fantastic. Thank you so much for your time. I will try first chance I can.

I will give you two pieces of advice:
1: Follow the instructions given to you by Creepy (and any instructions in the OP of ROMS) to the T.
2: Read then read some more. When you're done with that, read it all over again. Afterwards, follow step 2 again. This goes for searching about any issue you may come across.
Have fun, this device is really amazing once you figure out more about it

Good plan. When you get the cwm kernel, do a nandroid backup then pick any rom you like... (cm10 nightly just came out, if you like jellybean)
AOKP by Task650 is another JB alternative.
Which is better you ask? Gonna have to try them both! They both offer stability and great user experience for most who try them. Maybe you're a GB or an ICS kinda guy though!

It really doesn't matter much which kernel you choose for the next step, because it's only on your phone for a short time. Assuming you rooted with the Gingerbread stock plus root package, then you need a custom Gingerbread kernel which has ClockworkMod Recovery. I believe the links in my guide for the kernels are still working links.
The root I did said it was root + kernel. I take it the one with the entropy512 one click root+ kernel doesnt include the cwm. Im sorry im jist trying to understand the whole process not just do it. Alot of what i read doesnt click. Loke when I rooted it took me 6+ hours because I didnt know you want to save the file not open it when downldng it. also I read the deleting the tethermanager2.apk will open wifi/tether. True?

Forget i asked. I re read your comment. Ok its a stock kernel. So it wouldnt. I understand. A stock kernel probably would make it easier to return to stock. right?

Essentially, yes, but if you're going for custom ROMs, that's not what you want. There are easy ways of getting back to stock if all else fails.
You gotta know what you want first, before you move forward. I know you want tethering to work, and people here have recommended moving to a custom ROM because tethering does not seem to work for you on rooted, stock ROM and stock kernel. So do you want a custom ROM instead (you'll lose some of your current data via that route)? Or do you not care about ROMs and you just want wifi tethering to work now that you're rooted?
Assuming you want just the latter of the two options, I would recommend that you first try a custom kernel (this is different from a custom ROM, but note most custom ROMs include a custom kernel upon install). You mentioned Entropy's Daily Driver Gingerbread kernel, which is a great one. I'd recommend installing it and seeing if that fixes your wifi tethering problem. To install, use Mobile Odin lite version; you can find that apk in Creepy's guide. Download and save the zip from Entropy's DD thread, then extract the zImage file from it (make sure to use the name "zImage", no file extension, important) and move that to your phone via USB mounting. After that, in Mobile Odin lite navigate to the zImage file and flash it; viola, you now have Entropy's custom Gingerbread kernel and stock GB ROM. All custom kernels include ClockworkMod (no other way to get it), so you have that too.
If the custom kernel alone does not fix your wifi tethering problem, then maybe it's time to move to a custom ROM. With CWM, you can flash anything (ROMs, kernels, what have you) much more easily, but we'll get to that after you get the kernel, which is part of the process anyway.
These instructions are all repeated in paragraph 3a of Creepy's guide, and more information is written there, so I would recommend reading it thoroughly so you do understand. I know it's frustrating at first, but you'll get it, and you seem like the type to eventually get it right and understand what you're doing.
THANK YOU!!! I will try that tonight. That was very helpful info. So I CAN do this right from phone the? I saw there were some Apps that can do stuff like that but wasn't sure if they worked. I think I saw one linked to the superuser app. Ill keep you updated

I would recommend first getting the ota 4.0 ICS update from att. Upgrading from ICS to Jb is a lot easier and smoother. From opinion upgrade in CWM not Odin. Cwm is harder to hard brick device like Odin does. As long as you have Cwm you can recover soft brick. To get Cwm the easiest way it to find a kernel and use Odin to install it. Once you have Odin your free to try what you want. I prefer the new JB leak. Good luck

Also not trying to be a ****, but I would advise you too to read a lot more. (OP pay attention too) Flashing a custom kernel with Odin will trip the flash counter, something not easily reset and something you're much better off avoiding. And there should be no problems upgrading from GB straight to JB if you flash ROMs via CWM, so I have no idea what you're talking about when you say the OTA to ICS should come first.
To OP, I will give three points of advice. Please heed them well, and remember that they are for your own protection and benefit, not mine.
1. Never, ever, EVER, I MEAN GOD FORBID EVER, use ROM Manager on an SGH-I777. NEVER!
2. CWM is built into custom kernels for I777. It is not separate, so do not try to update it unless you want to flash a new/different custom kernel. Again, NEVER.
3. Read this guide at least 3 times completely, until you fully understand everything in it, before attempting to further modify your phone.
Now, if you finish everything I said and still have questions, feel free to ask after then and I will try to help you. Good luck and Merry Christmas! Oh, and hit the thanks button if you find my advice useful, please

I still run a stock ice cream, I'm officially going to root it and put a custom fw on it. It would be a miracle at this point if they updated it.
What is the closest to the s3 rom? I'm guessing its shostock3? I really want a stock rom, with all the samsung apps. I know people ask all the time what the best rom is etc etc, but is my assumption correct here? i777 here.
my only fear is that shostock will be worse on battery life than an official one, but at the same time, that could be a false notion with me.
Thank you for any input.

With any custom ROM you should get better battery life as opposed to the stock ICS ROM, as there are kernel bugs that drains battery at a faster than normal pace.
There is also an issue with the stock kernel that can permanently brick your phone (do NOT perform a factory reset or wipe of any sort unless/until you have replaced that kernel!!)
SHOstock3 can get awesome battery life.
so is shostock3 the only rom that gives me jelly bean + touchwiz 5 ? and the samsung apps ? I saw the music player is the same as the s3 etc??

Here's my suggestion: make a nandroid backup, flash SHOstock3 and see whether you like it or not.
I installed Fromaroot and rooted the phone. I'm trying to get CWM on there now.
I was trying to do it without odin and without using a computer much. Did I mess up the process doing the fromaroot, it did succeed. All I have now is the android recovery(which i'm guessing isn't much help?).
I'm trying to install shostock, but it looks like i already need a kernel that has CWM already on the phone before I install that? I don't want stuff that is already iterated to me repeated, and have the thread locked.
But can I use mobile odin pro to install a kernel with CWM? or should I really be using the computer right now to do all of this?
Thank you

Assuming the root process worked correctly, then you *can* use Mobile Odin (pro or lite) to install a custom kernel containing ClockworkMod Recovery. For more detailed information, please see the guides linked in my signature.
even though it says I already need a kernel that has CWM to install shostock on the official page?
sorta came off as most people will have already been flashed etc.
the last thing i want to do is brick my phone on the first attempt. Also what kernel should I flash, there is so much outdated info out there. I dont see anyone on here mention fromaroot but it worked perfectly, maybe it's a bit of a newer tool.

Read the 1st link from creepyncrawly's signature to get started.
Simple rule to follow. Look what version of Android your phone is running now, and then read the related posts for flashing kernel, ROM, CWM, etc. That's how I did it. This phone is almost 2 years old and of course outdated info is floating around.
For me, it took less than an hour to root/flash the phone, but days to read through all related posts.

I'm not sure what you're getting at here.
You started out with stock 4.0.3 (or 4.0.4.) Your stock kernel contains stock 3e recovery, which you can not use to flash custom firmware. So, to put custom firmware on the phone, you need to first flash a kernel containing CWM Recovery. (There is no stand alone recovery on this phone. The recovery is built right into the kernel.) You can do that by several methods. Using Mobile Odin is the quickest and easiest. It's almost fool proof.
And yes, the phone is starting to show it's age, and the guides are getting a little out dated. But the information is still good. What is important is understanding the process. You (and everyone) should understand exactly what you are doing before you modify your phone. Once you understand the process, you are much less likely to make a paper weight.
For a custom kernel, use one of the ones linked in the OP of the thread for 4.0.4 ICS, UCLL6 plus root which is also linked in my signature.

Just to recap, to go from stock to custom firmware
1. root
2. install a custom kernel containing CWM recovery. It should be a recovery that works with your current system.
3. use CWM recovery to flash the firmware of your choice.
4. profit
Thanks guys,
I've actually flashed a few phones for my friends, read up and 20 mins later i was off an on.
This was a bit more of a trouble for me though. Tons of ways to do it, many versions of this phone, half the time i would be reading and be like, damn this is not for the i777 can't take any chances.
i'm going to put that kernel on there , and then flash shostock3 , seems to be the closest thing to an s3 like experience on this phone.
I was / still am, heavily worried about battery life, something keeps telling me this is like going to cut my battery in half, i blame the experience on the t mobile g1, where i put all these roms on my friends phone and it just sucked away the battery.
Hopefully shostock3 does a good job though! ICS just isn't cutting it anymore

Not to worry! See attachment.
Admittedly, this was very light usage. But it gives you an idea what is possible.
Oh, and this is the stock battery that came with the phone in Oct. 2011. No telling how many charge cycles on it. At least 4-500.
got shostock3 on it, runs beautifully
battery life so far is just as good or even better than stock, lots of bloatware gone.
Thank you to everyone.
Fromaroot > 4.0.4 custom kernel (mobile odin) > shostock did the trick, couldn't be easier, if you ever really motivated and didn't mind waiting a bit, i guess you could do that whole process with just the phone.
only thing i used the computer for was transferring files.
and now 4 days later the official one comes out!
Everyone lost hope, even me!
I'm tempted to try it out, but at the same time, i'm quite happy with shostock3

mr-cook has a modified stock version. It's stock system plus root and busybox, and the jebo kernel. So if you wanted to try it out, you could make a nandroid backup of SHOstock3, try out the cooked rom, and if you don't like it, go back real easy.

Try the Alliance Rom, it has the Samsung app store and you register with Samsung when you first boot up.
