Refer page 1 if you wish to know how to setup

ROM Manager is not fully compatible with SGS II - still some bugs. If it is good, I'd have highly recommended it in Page 1. Not only me, ,many XDA'ers will propose to use it
When you use Rom Manger, first thing it will change your recovery on phone. Than depending on your rom type, kernel - when you try tyo backup - it will fail. And assumimg you can backup, most probably you will get a fail restore

When we want to use a backup/restore program , what is important you mjust have a 100 % good backup and a 100% good restore. There is no in between both must be 100%. Anyway you can try if you wish and please update us if you are successful

I suggest you :

1. Use Titanium Backup to backup all your apps/data
2. Use Odin to flash Chaimfire CF4 - this will root and install a Clockworkmod recovery
3. Boot to recovery and select backup
4. Than only proceed flash whatever rom

Just flash the mod in recovery but before you do that read the thread and make sure your firmware is supported

Then just go to download mode, use Odin flash Chainfire4 ( KG1 version ) to get back root and CWM

YES you can do repartition - your internal SD card will be wipe completely clean; so backup any important stuffs you have - eg your games data, newsfeed/rss feed, etc . After successsful reinstall, just manually copy back. What I usually do ( lazy method ) I just copy everything over to my hard disk and than copy back everything ( except the folder Android, lost.dir, temp as these will be recreated back when you reinstall or restore apps)

See page 1 rom section post #4 - the link and tutorial is there

Next time, read carefully , I wrote minus 75mV NOT 750mV
Launch Tegrak
Load overclock module
Select Optimization
Scroll down at each level under core voltage tap on it - just select the reduction figures you need and APPLY

Everytime you select an adjustment you will see a prompt checking stability

After you have finish, go back and select SET ON BOOT

The app will test your settings watching stability about 300+ secs

The PIT included is for those users who would like to repartition/reformat the internal SD card to have a complete new start. It is up to you. Select PIT will auto repartition and you will lose all your 3rd party data, apps, settings etc

I STRONGLY suggest you read my TIPS on rom flashing page 1 post #4. Based on the string of questions you are asking, you are just like shooting in the dark. Do make some effort understand the basics. The line of questions you are basically asking to be spoonfed - and that is not good.
And to answer your question - it has been replied and is very clear , why are you still asking about is it necessary to root ??? NO NEED - once you flash Litening it is auto root. And users here has already told you flashing this rom will not wipe your data - and you are asking again " need factory reset ". I give you my personal advise - it is GOOD to factory reset to have loess potential of bugs. If you want easy way out , which I see is most probably what you want - than no need . The choice is up to you

I don't use TouchWiz at all ; if not I will answer you . You are repeating this I think the 3rd time already today. WHy don't you exercise initiative and google solution on the web instead of repeatedly asking here - try fierst XDA ???. I will do it and I will see whether I can find an answer for you out from lowyat
Immediately I want to ask you, do you know first screen starts as 0 NOT 1 - could this be the problem - just guessing since like I said I don't use it

This post has been edited by benny888: Jul 12 2011, 10:47 PM

Read my last line - you miss it ; if you want homescreen at number 4 - you should set it as 3
What rom are you now on - personally I don't think rom affects it

Did you change permissions when you edit the file ?

If you are trying to duplicate your phone to be exactly same as stock when you bought it - my 2 sen advise is forget about it. An experienced tech will know straightway that you have change roms by just looking at the kernel version. Based on your phone serail number they can match back the exact kernel version number. You could fool the seller to take back your unit but not the technician. Unless you managed to install back an exact kernel version

If you have been following the thread, at the previous one ver 6 or 7, there were 3 users who got a 1-1 exchange for their phones even though is rooted and flashed. What I am saying here is , if one is concerned about warranty, my advise is always stick to stock rom - don't root , don't flash. If one starts to root and flash, be mentally prepared that there is a possibility you cannot make any claim. If your phone is rooted/flash with cook rom and you can still make a claim FOC , it is a bonus. If you need to pay for any servicing costs, just accept it

NOt only me but quite several users has reported ( in SGS, Galaxy tab ) thread that claims were successful even phones flash with cook rom. Maybe one can say they are lucky. If consider lucky, so be it - it is a bonus . As said, just be mentally prepared you cannot claim FOC. I have send in my previous SGS three times for service - re-flash roms cos bricked ( my phone was one of those with the 3 buttons disabled cannot go to download n recovery mode ) - in all 3 occasions the tech knows and even advised me to be more careful flashing such phones with 3 button disabled and service was FOC. And the SGS was an AP set I bought in KL but I send in to Spore to service as nearer my place. They don't even bother to ask for receipt or warranty card - just key in serial number to process. My favorite quote is my 2 HTC phones flashed with cook rom - i got motherboard replaced too FOC. My ipod touch jailbreak I got it replaced too FOC. At the CSL m300 thread - several users got phone 1-1 exchanged even though phones flash with cook rom. Several Galaxy Tab users got their battery replaced FOC even with the phones flashed with cooked roms. My point is simply - don't be too paranoid over these.

Latest news about a month back, Samsung has pass phones to the famous Cyanogen team for them to mod roms . First time a manufacturer ever do this. Sony Ericsson has unlock bootloaders ; HTC will follow soon. Motorola has also said they will follow suit. These manufacturers know there is an expanding market of users who wish to mod their phones and the recent moves to acknowledge it is encouraging

Another paranoid user - what has animation got to do with screen display ?? It is just a display of software effects

For new users and to be user - the SGS II operating temperatures is higher than most other Androids, simply because it is dual core and its thinness transmit heat easily. Some users like to use the word " hot" - I'd said is warmer than normal. The word hot connotes a feeling of uneasiness and a possible burning effect on your skin, which it will not. Most users I believe will use some sort of casing or backcover - these will reduce the effect

If you have been using single core Androids 1 GHZ models before - you will not experienced the " hotness" as a serious concern, I'd say generally is about 2-3 degree centigrade more. Those who are coming over from say Blackberries and Symbian will feel the difference more obviously

Use an app to monitor battery temperatures - batterylife widget is a good free app. It shows you the temperature and voltage and is quite a well designed widget

These are guides to operating temperatures ( degree centigrade ) basing solely on my usage :

Idle not in use : 28 - 31
Browsing : 32-35
Gaming : 35 - 40
WiFi hotspot : 35 - 45
GPS : 35 -45

With prolong continuous usage over several hours it could hit 50 but I'd think such usage should be minimal unless you are one freaking gamer
I read the phone has gone to extreme testing till 70 degree and still performs well ( will post back the link on this if I can find it again )

There are many ways you can reduce the temperature if you are uncomfortable:

1. Use SetCPU : Scale down CPU speed - do you really need 1.2 GHz power ?? most stuffs works well within 800-1000 Mhz
2. Use SetCPU - set profiles under different conditions

Undervolt core voltage - using Tegrak Overclock Ultimate

Read Page 1 FAQ on battery issues where I have detailed this point - will not repeat here . These will also save battery usage

Interested to know how other users experience and feelings on this issue :

Ask wkwong77 as his post # 1011 says:

I am on XXKG1, root with CF4 and flash back stock kernel XXKG1.

Yes. Just installed it will overwrite the default
More user friendly with s nicer interface

No, it is OK ; no issues with it

Why not ? I pay for all my apps . I never use those blackmarket apps. Android apps are not expensive. It is an egg and chicken situation. If developers are not supported, do you think they will still continue to improve their apps ? After all, the apps are not expensive ranging RM 3 to 10 mostly. I used to be involve in programs development for several years with my IT staffs and I do understand the amount of work/effort , pain and headache they go through especially when comes to debugging. Using apps without paying is just plain simple stealing intellectual property. Those practicing it is just as guilty as a petty thief.

I know of many users who are so proud loudly proclaiming they don't pay for apps when they can get it free. They think they are very smart , which infact they are not. One day, probably their children could be involve in programs/software development and they will feel the pain when their children cannot cari makan as all their efforts are just being pirated and stolen away
