Help with upgrade to ICS - Galaxy S II Q&A, Help & Troubleshooting

Im new to all this flashing and messing with mobiles and am a little lost so i need some help. I have a SGS2 running Checkrom V4 which im very happy with i have CWM installed and my rom backed up but i would like to upgrade to ICS. My issue is after doing loads of reading im not sure that its done through recovery and when you do have ICS on your device you don't have CWM so no easy way as far as i can tell to go back to gingerbread. I have odin on my PC that's setup and mobile Odin on the phone i just need someone to give some idiots instructions, what worrys me the most is no recovery. Is it worth waiting for a official ICS to come out that's stable with CWM or some other easy way to change roms, as i understand it some country is due it officially today.
Does someone have a idiot guide they can do for me of a decent stable Rom and how to install it and how the recovery works, i would really appreciate it, as all the threads have multiple parts that need flashing not just a simple rom there's add this and that. That doesn't worry me but i worry about becoming stuck on a ICS rom that's a load of ****, ideally i would like just a standard stock official UK rom that updates itself OTA or is stock with root and CWM but iknow we could be waiting a while for that.
thanks

Stickies...

Those are about the only thing i hdnt read.
cheers

[Q] Root now or wait for Android 2.3 ?

I am running stock samsung firmware on the T-Mobile Vibrant.
I had been holding off on rooting/rom-ming it because i was afraid of bricking.
I think i want to root now for 2.2, and have been going over the forums.
However, I need a method of rooting which will also support my upgrading to a 2.3 rom later on when it is released. Because according to what i have read, the safest way to get to 2.3 would be to to go back to a stock 2.1 and then repeat whatever steps are given.
TL;DR: I need an easy point which gets me to Froyo right now which will aslo get me to Honeycomb later without too much brickage chances and complications. Thanks
You can root keeping the stock rom and still receive the OTA updates

There is a ton of info on this site to assist IF you want to install a custom ROM. There is a great video that shows you a lot of what you need to do to be able to install the ROM. Take a look around and read read read. It is a fairly simple task and I have tried to brick my phone and ODIN has always come to the rescue!http://forum.xda-developers.com/showthread.php?t=821468

[Q] Consequences of rooting my rezound

Hey guys, Im completely new to rooting and im getting a rezound in a couple days and i just had a few simple questions that i couldnt find the answers too else where.
1. If I root my rezound will i still be able to receive all the regular updates like the verizon updates and upcoming OS updates? If not what can i do to get those?(Correct me if im wrong but I would assume that i would have to reverse my root somehow if the answer was no but im not sure how to do that)
2. If i root do i have to install a ROM?(Note:Im planning to remove htc sense as soon as i root and install a new launcher...idk if that has anything to do with having to install a ROM but i figured i should ask)
if you plan to stay on the original rom after you root, im pretty sure that you will be able to recieve the actual ota when its released. but you say that you plan to delete a lot of htc stuff (im assuming bloatware and things like that)...i would HIGHLY recommend just flashing a rom with all of that done for you. unless you know what youre doing, removing htc stuff by yourself can be detrimental to your phone and cause it to not work as it should. im currently running cleanrom 4.1 and its incredible. flashing a rom would be the best way to go
hope this helped.
yes that help, thanks. so if i were to use cleanrom 4.1 and i wanted to get the official ICS update when it released, what would have to do to be able to install it?
Forgive me for being a noob but I am going to attempt my first post I usually just read but feel I may be able to give a quality answer. SO, If you make a nandroid backup before flashing any rom's you will be able to revert back to stock at any time. You can do this via a custom recovery. In order to get an OTA, like the ICS one that is coming soon, you will have to reload your stock rom. Simply put, you cannot get an OTA with a custom rom. If you want a custom rom now and an OTA update later, make a backup and revert back to it when the OTA you want is released. Hope this helps!
One thing that nobody seems to ever mention is do NOT do anything to your phone for the first 30 days because you want to make sure you have a solid phone.
If your phone is constantly malfunctioning because of a problem with the phone, but you have already rooted your phone and flashed a new ROM, then you're going to be nothing but frustrated because you will think it's the ROM, or perhaps something you did when rooting the phone.
If you have a problem within the first 30 days and you have not rooted or flashed a new ROM all you do is walk in to Verizon, tell them the phone is brand new, but having issues with [insert problem here] and you get a brand new phone with all your info transfered for free, and another 30 days to make sure your replacement is not defective as well.

What device are you coming from? I went from an OG Droid1 to the Rezound and actually love Sense. I think you should try it out first before cutting it out completely. If you wish you can leave the stock Status Bar/SystemUI and install a different launcher as that will disable most of the Sense elements, ~90% of it. As far as OTA's go, unconfirmed whether or not you can update from the recent leak. Make sure you have stock rom available or do not flash the recent leak and choose one of the older roms (Can always RUU back to the stock rom when official hits). I suggest Rezrom 3.1 with the old firmware patch as for me it's been so far the most stable and best battery life ICS rom I have used.
1. No, you won't be able to get OTA updates. But don't worry too much about that. It takes about a week, but the devs will post a manual method or you can use the RUU that usually preceeds the OTA by a day or two.
2. Don't try to disable sense from the stock ROM. It'll be trouble, I tried it for a while back when we only had temp root and it made it buggy and smoked the battery. Flash some ROMs and let the pros get that stuff worked out for you (and throw your favorite dev a few bucks to keep him interested!)
The real consequence of rooting though is the countless late nights flashing yet another new build or theme or whatever. It's kind of addicting.

[Q] ICS Update - SGS 2 Rooted 6 months ago

Thanks for reading - I'm a noob.
I came here to learn about rooting devices over 6 months ago and decided to have a go at rooting my SGS 2 to remove the bloatware and speed it up a bit.
Performance has been great - I left the stock firmware because the OS/ROM was not a concern to me. I simply flashed the kernel with CF Root: CF-Root-SGS2_ZS_OZS_KF4-v4.0-CWM4.tar
Now I am led to understand I would need to flash back to my stock kernel to allow the OTA update for ICS - the only issue is I cannot find any available downloads for I9100TDVKF4 - Telstra's stock kernel.
Now I read somewhere a reply to a similar question was "just flash it with a new rom, I dont know why you want to go to stock" - Well I want to update to the official ICS. I was under the impression that would be available a long time ago and never was. I just want to....
Please can anyone help me to point out where I can find that kernel? perhaps there is a different kernel i could use?!
Is there any ICS firmware I would be able to download and flash to the ROM using Odin whilst keeping my phone rooted?
I found this place really helpful in how to root and now I just hope someone can help me get onto ICS!
Cheers
Is there any ICS firmware I would be able to download and flash to the ROM using Odin whilst keeping my phone rooted?
No only custom rooted firmware .
Try Checkfus for your stock firmware download and flash via Odin .
Dont confuse yourself with kernels without understanding .
ICS on Checkfus or Kies for your phone install otherwise wait until your provider releases .
or flash your original saved firmware that will overwrite root .
jje
Thanks for taking the time to reply mate....
Dont confuse yourself with kernels without understanding - dont worry ive been trying not to but it seems thats the only thing i changed on my phone when i rooted it so i was lead to believe i needed to change that back...
My provider has just released new version of ICS but i cant actually install it once ive downloaded it over the air it only gets to 8% then reboots itself and i believe thats because the phone is rooted...
or flash your original saved firmware that will overwrite root - I dont know if i backed it up correctly on the guide i was using!!! The only thing i backed up was the apps using titanium backup so now i feel im stuck!
Use check fus down loader and get the official ics ROM.
It's under i9100t Australia/telestra
Problem solved.

[Q] First time flashing Cyanogenmod: Help needed on installing CM10 or CM10.1

Hello there!
I'm a complete noob when it comes to rooting and other related stuff so I could use some help. I want to install Cyanogenmod 10 (or 10.1 if it actually is usable and mostly stable / it is easier or more noobproof to install) for the first time and I would like to know what do I need to know before starting to follow any tutorials for flashing new kernels etc. There are just so so many tutorials for this and I don't know which one I should follow to not brick my phone as I just can't afford a new phone if I manage to brick this one and I just want to get everything out of this phone.
All this Clockworkmod, Odin, Rooting and everything just confuses me and I don't know where to start. If I've understood correct the first thing I should do is I should download some custom kernel as this is something which runs "under" the Android (kind of like bios for computers?) and allows me superuser access=rooting? Then after I got new rooted kernel done I should install Odin or ClockworkMod which acts like a "backup" if something goes wrong? And lastly I should flash in the Cyanogenmod 10 or 10.1 depending which is more hassle-free for everyday use (I'd like to get as much customization as possible for my phone) and has more features and more stable.
My phone model is GT-I9100 so it's the international one (I live in Finland so no Verizon or other model of it.. that much I understand at least) and my Android version is 4.0.4 the 100% stock version of it.
I'm tired of waiting for the slow Samsung people in Finland to get the official Jelly Bean release to be done and I want all that project butter goodness NOOOOOOW. So...
TLR: I have Samsung Galaxy S2 (GT-I9100).I want to get CM 10 or CM.10.1 the noobproofest way possible, can't afford to brick. Can you guide me to a good tutorial with easy to follow orders and up-to-date versions of Cyanogenmod as I don't want CM7, but the latest GOOD Jelly Bean version or just tell me how to do this? I will answer any questions you might have about my phone or anything. I'm not stupid when it comes to computers, but phones are totally new thing to me and I don't want to flash new jelly bean with some random tutorials from youtube as I'm afraid of getting a bricked phone (or missing out some great features from other Jelly Bean releases). I want the best for everyday use, most stable and the one with most customization options version of CyanogenMod Jelly Bean for my S2.
Thanks in advance! I will be monitoring this thread actively so I answer possible questions quick.
I think you're a bit confused at some points.. I assume you're on ICS now. First you have to root your phone by flashing a custom kernel (which gaines you root access) like Siyah WITH Odin. Steps are descriped in enough guides on xda.
When you've rooted your phone, it's best to make a Nandroid back up in Recovery Mode (CWM), you get CWM automatically with flashing Siyah, just in case anything goes wrong.
After this you may choose to flash a custom rom, mostly done with CWM recovery. Steps for this part are almost always written at the instructions on the first post of a rom thread, so read them carefully.
About Project Butter: this isn't fully implemented in CM, so flash the JB-leak from Samsung, or a rom based on it (or wait for the official release).

Yes I'm running 4.0.4 forgot to add that sorry. That clears many things up thank you! Oh... I thought that Project Butter was fully implemented on every 4.1.X ROM. Now I'm having hard time deciding if I should flash CM10 or just wait for the official Jelly Bean release which is supposed to come next month in Finland... I just want my phone to be really, really fluid and I'm not really pleased with this current 4.0.4 and all these unneeded programs like all the Samsung Hub programs.

[Q] Trying to go from 4.0.3 (rooted) to something stable and JellyBean

To start my TF-201 is only rooted. I have kept it on stock ICS 4.0.3 for a long time and now want to flash something more current. All I ever did was root it with Sparky many months ago and nothing else. Since these early days many things have changed in the development area for the Prime and I feel I should bring it up to speed. My problem is there is a lot of different instructions for unlocking and rooting for people that have updated to JB and I don't know if any of these things still apply to my current ICS rom.
Do I have to unlock first or can I just download rom manager from the market and flash a recovery without unlocking? When i go to the Asus site, I don't even see a link to download the unlock tool anymore. I would like to just flash the latest stable CM rom but don't want to mess things up because I accidentally followed misinformation. Any help would be greatly appreciated.
