Phone just freezes when I root it - Galaxy S II Q&A, Help & Troubleshooting

Hi All.
I'm relatively new to all this so go easy on me.
I've got a Samsung Galaxy S2 on T Mobile.
Model Number: GT-I9100
Android Version: 4.0.3
Baseband Version: I9100XXLPQ
Kernel Version: 3.0.1 5-i9100XXLPQ-CL223505
Build Number: IML74K.XXLPQ
I've tried to root it using a method I found on here, I think it was by chainfire, the Odin app said it was a success but when the phone reboots it just freezes and doesnt go any further.
I want to have the cyanogenmod rom on my phone with it fully rooted.
Any help would be greatly appreciated, I have searched this forum for answers but its pretty vast.

What kernel did you use to root your device?

is this a kernel? if so this one
I9100XXLPQ_I9100OXALPQ_XEO

---

It's a ROM, we need information about kernel.

That is a full firmware, not a kernel.
You said you used something from chainfire. If you can't tell us, perhaps a link to what you used would be helpful.

initially I think it was this

This is an insecure kernel for android build UMKK1, which is Gingerbread.
You have an XXLPQ build, which is ICS.
You need to use a kernel that is closer to your build. There is an LPQ kernel in the CF-root thread, flash that. (make sure to use the one labelled as "proper", it fixes some stuff)

Originally my phone had Gingerbread - which is why I used that kernel. However, I then thought it had rooted. So installed ICS. Downloaded Rom manager and it tells me my phone isnt rooted.
Should I still use that one?
Do I need to do anything after that?

Is the information in post 1 still accurate? Is that what is CURRENTLY on your phone? Then use the LPQ "proper" kernel in that thread I linked. Instructions are in post 1 of that same thread, but the short of it is: find the kernel that matches your build, and flash with Odin. (I already told you which one) That should be all you need to do. That will show the Triangle when you boot the phone, but if you don't care about that showing, then you're done.
So you're saying your reason for using the UMKK1 Gingerbread kernel was because you were PREVIOUSLY on Gingerbread? Well, you installed ICS. Your kernel changed along with it. You'd now have to use an ICS kernel to root ICS. Make sense?

Yep, makes sense.
Yeah the above is what is currently on my phone.
I'll give that a go. Thanks for your help.

Hi there, it rooted, so thanks for your help with that.
However, I tried installing cyanogenmod from the latest one listed in the Rom Manager. It downloaded, the phone re-booted into recovery. I deleted cache and data, then installed the zip file from sd card, however it came up that it had failed and was aborted.
So now it's rebooted and is back to 4.0.3 but with all my data gone.
Man this sucks.
Hope you can help mate

I don't use CyanogenMod, but I would avoid using ROM Manager if I were you. Why don't you just follow the instructions in the CM discussion thread? And which CM are you attempting to install? CM7, or CM9? (one is Gingerbread, and the other is ICS)
BTW - you would have had to delete all data, going to either version of CM anyways, as file system is a bit different between AOSP and Samsung based firmwares.

The newest one, I think it was CM9.
To be honest mate there's so many threads and discussions unless you have a real grasp of it its not easy

is there a way of me telling if clockworkmod recovery is installed?

CM9 discussion thread. Has installation instructions in post 1, which don't involve using ROM Manager at all. As I said earlier, I'd avoid using ROM Manager; it often misbehaves on this device.
Here's some advice... even though I don't use CM (7 or 9), I found that that thread in 1 second by typing "cyanogenmod9 i9100 xda discussion thread" into Google. It was the first result that came up.
I know forum search sometimes is down, but I actually prefer to use Google for my searches anyways. You can even limit searches to a specific site by including "site:" followed by whatever site you are interested in limiting your search to.
For example, if I wanted to search the xda forums for i9100 rooting techniques, I'd Google:
site:forum.xda-developers.com i9100 rooting techniques
This will return a Google search for "i9100 rooting techniques" that are within the forum.xda-developers.com domain.
Rule #1 of the forum is to search before posting anyways... I know you're new to most of this, but you'll find people will tend to either not help or will be kind of mean if you post commonly asked questions.
Hope all this helps.

Boot to recovery. You'll know because CWM recovery has MANY more options than stock recovery. Stock recovery you can only wipe data/factory reset, wipe cache, and wipe dalvik cache, and maybe a couple other options. I don't exactly remember, it's been so long since I've had stock recovery.

Okay thanks.
Believe me I spent 5 hours last night searching for answers and reading.
I appreciate your help.

Sometimes it's just a matter of inputting the right search terms.
Anyways, I'd also advise you to follow the "noob-proof" installation instructions only on that CM9 discussion thread. It is the most straight-forward, and involves the fewest amount of steps.

now its gone into kernel panic upload mode
this is a mare

Were you following the "noob-proof" instructions as I advised?
What exact steps did you take?
