stevenz: I've undervolted quite a bit, takes a bit of playing around to see what's stable, it's not really worth bothering given the powerdrain improvements. It runs fine even at 1600MHz, but I underclock down to 1Ghz as it's more than fast enough and I'd rather have the battery last longer. 


Have you ever checked out how much time your cpu spends in each state? The time spent in anything over 800MHz is minimal with normal phone/mp3 player use.

Try CPU Spy (free in the market). It'll display exactly how much time spent in each state, including deep sleep. It's a fantastic little tool.

Brendan: 

[partial quote] Get into CWM by powering off the phone, and hold in volume UP and home key; then hold in power for 5 seconds odd. [took a bit out]

Love the closing line.  Hmm, does that mean ALL men want me and all women want to be like me?  I suspect it doesn't work the other way around  Wink

When it comes to knowing when to take your fingers off the 3 buttons.  As soon as you see the Samsung boot logo appear, release the buttons.

I often fire up Cut the Rope or similar little passtime game which tends to max the CPU if I don't limit it, admittedly in that case the power used by the display would be by far the bigger issue, but it makes me feel better :)

Does this Guide looks about right for rooting my sgs2? - http://androidadvices.com/how-to-root-samsung-galaxy-s-2-i9100-tutorial/4/

So let me get this straight, I root the phone first, and after that I install a custom cognition ROM?

I also heard after installing ROM I might have to root again?

sounds good but couple of areas I was lost -

" But the easiest way to do it all is to use ODIN to flash a chainfire CF-root kernel; instructions are on XDA. As if you need more help. "

" Your phone is now rooted AND has CWM installed. " <--- how? I thought I was just doing a root? how did I install CWM ?

"Probably the first thing you want to do is a backup of your current system. Got to the backup menu. Self explanatory. That is a nandroid backup."  

Current system as in the one I'm using right now before trying to root?
I thought  nandroid backup only works with rooted phones?

And above all, how do I backup my current settings, apps, games, files which I've got on my unrooted phone?

Sorry about heaps of questions, couldn't find straightforward answers to them by searching, and didn't want to assume answers and screw up the phone...

Hi there
The kernel (ChainFire) that you use to root includes CWM.  It's part and parcel which sort of kills two birds with one stone.
You need to be rooted in order to do a nandroid backup, unless you use something like ADB
And you need to be rooted in order to use an app like Titanium Backup which will backup all your apps and data.

No need to apologise for questions :)

Awesome thanks.

So just double checking because there are different opinions all over the forums.

Just rooting my phone - does it wipe off all my data and settings? That would suck because I need titanium backup to backup my stuff in the first place.

Or my data only wipes off only when I install custom ROM?

Thanks for the patience, hopefully my questions are useful for someone else in the future who is looking for straightforward yes/no answers rather than having to search xda and get million opinions.

Rooting your phone provides access to the root directory of the phone.  There's nothing else touched.  You can boot up the phone as per usual and you'd know no different.  Except of course you can now use apps that require root access :)

Depending on the customised ROM you decide to flash, some will recommend you wipe the phone, that means a FR - factory reset (which is an option in the CWM menu from recovery mode).

Others don't require you to factory reset.  Cognition don't require you to do anything, and have built scripts in to wipe the cache and Dalvik cache.  Both cache wipes are often recommended by other rom makers.  So it's nice that this is all part and parcel of flashing that particular rom.

Using Titanium Backup means that when you restore the apps, the data can be restored too.  It can also just be used to restore apps only.  The default option is for Apps + Data.

Make sure that you've got all your contacts in Gmail.  So many people flash a rom then find they've lost their contacts and can't connect back to Kies (which is a pile of poos) to sync. 

I would suggest having a quick look on YouTube. When I was starting out I found a number of good videos.  It was more just to help understand what everything would look like so I never doubted whether I'd stuffed it up.

Here's somewhere to start on understanding/seeing Titanium Backup

Sometimes a picture speaks a thousand words :)

If you Root by just flashing Chainfire's Root kernel then it doesn't wipe anything - get into it!

Even installing custom ROMs doesn't neccessarily wipe your stuff...

I've just flashed Cognition 1.15 and didn't need to reinstall a thing.  Simplest flash of a full rom I've ever done in recent times.

Glad you've got it down pat, because it looks like 1.20 is coming out tomorrow, based on KG2 with a new kernel version too!

I'm intrigued to see how they can improve on what is already close to perfection. . . . Around 34 hours of use now and it's just dipped below 50%. Cool

Yes, read Chainfire's CWM thread on xda about the triangle and how to get rid of it if it bugs you.

Yes.

Ah crap. I followed instructions from youtube and http://forum.xda-developers.com/showthread.php?t=1056334

so forgot about using the link networkn provided - http://www.geekzone.co.nz/forums.asp?forumid=97&topicid=83026&page_no=79#495257  :(

So does that mean I still need to do the whole thing again but following the above link?

Or can I go on and flash cognition now?
