Rooting your phone....

---

Just thought i would put this hear as any newbie's like me might think they know about flashing roms etc but you gotta be more careful with the SGS than any other phone i've rooted before IME...

I've always had HTC's before this first the HD2 then a Desire HD with both of those phones pretty much you can use whatever rom is on the appropriate XDA forum once you've read how to root and flash CWM...

My findings with the SGS are totally different...
I presume because there seem to be so many different versions around...

My example

Had my phone back from repair yesterday pretty keen to flash a custom rom on it, so firstly using odin i flashed Clockwork Mod Recovery 5.0.2.3 which after reading for a while i thought was a suitable Clockwork mod...

After installing this which seemed to work i had the CWM menu etc i flashed Checkrom V4 but had issue's with the display quality grey's/blue's are really sort of washed out colours...
Tried changing the kernel with the kitchen pro but that didn't make any difference...

Also i noticed messages in recovery saying "can't mount e:" on a few lines

Rom seemed to install fine too but as mentioned above had screen colour quality issue's...

So i re-installed the vodafone original rom that came with the phone and the colours were back as they should be i then did some more reading etc and found...
CF-Root-SGS2_XW_OXA_KK5_v5.0_CWM5

and this seemed to install properly i've put this time a Miui rom on and everything so far seems fine....

I gather though you need to select the correct CWM to suit the correct version of your phone ?

And even if it looks like its installed if you get the "Can't mount" messages when you try to wipe data its not installed correctly...

Sorry if this all seems obvious to the guys in the know but coming from a different brand where every rom and kernel pretty much seems to work with each version (provided you use a miui kernel with miui etc)

you really do need to be more cautious with the SGS 2 and get the correct rom/CWM or you can cause issue's i'm wondering if sometimes physical issue's as my phone's been off for repair 3 times... fingers crossed its sorted now...

I personally found it much easier!!

You just need to follow the instructions to the t... I personally recommend noobs to use the zerg rush exploit until they are comfortable with the phone and they have increased their knowledge. And then to flash with odin etc...

The problem is that Samsung marketed over a half dozen completely different phones as the "Galaxy SII". Many have completely different hardware by necessity due to running on different carriers. Some firmwares can kinda work with other phones (GT-I9100 with SGH-I777 with some minor tweaks), but for the most part, you have to stick with your model number. It's not exactly rocket science, but it can get easily confusing.

I have the HTC Desire as well and the difference is that that Samsung don't lock down their bootloaders like HTC (at least the SGSII is open). Therefore you might be looking for additional instructions which aren't there, as they aren't needed. Check out the many threads that discuss rooting.

but for the most part, you have to stick with your model number.

Thats what i thought but i've had issue's using I9100 CWM on my I9100 phone...

I need to specifically use the later version i posted as the 1st version that i thought would work wouldn't properly, dunno if maybe later phone's are slightly different mine is 6wks old...

Dunno thats what i found confusing.

I agree with the method of rooting the phone using Odin is easier than rooting the HTC's whats confusing for a newbie is matching up the correct roms, kernels,CWM that are 100% compatible with your phone, i presumed if i go to this section of the XDA forum "I9100 android development" that all the roms would work, but i'm finding most are making my phone's screen go funny, or at least the CWM might be not sure if the rom or the CWM bad install was to blame...

To add to the confusion, not all I9100 models are equal, either.

There are the standard I9100 models.

Then there are I9100G models, which have completely different processors (Tegra instead of Exynos) and GPUs (PowerVR SGX540 instead of ARM Mali-400). Firmwares for I9100 and I9100G are NOT compatible with each other for this reason.

There are also I9100T models, which for the most part, are simply Telstra branded I9100 models, as far as I know.

There are also I9100P models, which is the same as I9100, but with NFC added. MOSTLY the same, I9100 firmwares work, but I9100 firmwares will blow NFC support away. (but there's a re-enabler out there somewhere)

So when I say "stick to your model number", I mean, your FULL model number.

You either have a non SGSi9100 or one of the obscure variations or you are doing something wrong .

CWM roms kernels modems mix and match
i have yet to find a kernel that has not worked on any rom likewise all variations of CWM . Their are only two potential problems one wrong CSC and you may need to enter network settings yourself ,CWM a backup on CWM4 may not restore on CWM 5 . Modems are interchangeable .

At present i have three modems and five kernels all flashed within the last two weeks on existing rom .
