Rooting Galaxy S2

[ajayashish]

Hi,
I want to root my device and want to know some thing before I do.

1. When I root, will all my data be lost. I know I need to take a backup, but will all the contact and SMS will be deleted

2. After rooting will i be able to revert to factory setting in case I have to go to service center

3. Is there any user here who is using a rooted S2.

NO.

rooting will root your mobile i.e. allow you to grant super user permission to some specific apps as well as add the superuser app (using which you grant those permissions) to the mobiles installed apps. you can unroot at any time. Though you may have to uninstall superuser manually.

So if you root and start kicking out apps then yes you may have trouble going back to the old state. There are 2 ways out of this: flash the stock samsung firmware again or if you have taken a backup somehow, restore it.

^^ Ok so here are some more questions

If none of the data is deleted like contact and sms then does rooting not format the phone. I was assuming that rooting will install the OS again.

If I root, does it effect the warranty and if yes, when i revert back will the service center be able to know that I have rooted once.

When I root and then install a custom rom, then will the data get deleted. I want to install the pure ICS rom on my S2.

Well rooting helps to install a lot of custom roms on your phones. I wanted to root as I wanted to experience the PURE ICS rom on my S2. This is only possible using rooting.

There are a lot of roms available on internet with a lot of advantages. If you are using Galaxy S2 or nexus then go to www.galaxys2rom.com and check the advantages of different rom.

unless the service center got some really expert DEVs that know where old logs are saved, they won't know. Actually they won't bother checking all these most of time time as its pretty much impossible to know if Android is customized using themes/launchers or the rom in use is custom rom unless you start checking the about page.

When I root and then install a custom rom, then will the data get deleted. I want to install the pure ICS rom on my S2.

phone memory (contacts, sms)? yes.

[ajayashish]

thanks for the info. now i have a very silly question.

when i started the phone i coonected a lot of fb profilw with my gmail contacts and phone contacts. so now they appear one. is it possible to retain that so atht i dont have to undergo the same pain of connecting them after i have installed a custom rom.

also which one according to u all is the best rom for S2.

i think you'll need some kind of app to backup your contacts as google sync will just backup the contacts and not the FB profiles associated with it. GOContacts should be able to take proper backup and restore it later.

no but to be in safe side use mybackup or gobackup to backup your data

2. After rooting will i be able to revert to factory setting in case I have to go to service center
yes u can

3. Is there any user here who is using a rooted S2.
yes , im using it with rooted from past 4 months and flashing rom,
pm me if u want any thing , lots of guides is there and search a guide for your android version and baseband
also take care when you flash radios

Does Kies save the connected contacts.. and after rooting and using custom rom can i use kies to sync back the contacts

[rickson23]

Does kies work after rooting?

@Ajay: Stock ROM is always the best. Most bug free out there. You can anytime remove the unnecessary bloatwares if you don't want them.
I never used any custom ROM and never will, but still of you're so keen to taste then CheckROM for GB seems quite stable and good. Heard V7 is also coming for ICS. For Pure Google experience (in which I don't believe) you might try Google Nexus ROM.

Lol come on accept you haven't tried most of the best roms out there. There is a pure rom which is built from aosp sources and gives pure Google experience I know cause I was a nexus s user before switching to s2. Also it depends on how you modify your rom and which kernel you use. And how you modify root settings for your requirement

Lol. Sorry I am not a person who comments without using any thing. Course I've tried them, sorry, they bring this and that bug always, or a missing feature, sorry I am not using that in my 700$ phone. Better use/have 8/10 good features rather than having 2/10 great features and missing other ones. Sorry I am not a person who could be sold by 'flashy' or 'gimmicky' things.
Hope you got my point

@ajay,
Your google account will keep all your contacts,just make sure to sync your calendar and contact before flashing a new ROM.Sorry missed out the FB part,no idea as I do not use FB.
But,I will also suggest to use the stock ROM,use a good custom kernel,debloat the stock,you are good to go!
There is nothing magical in custom ROMs,most stock based ROMs are basically photoshopped bunch of apks.
AOSP/AOKP ROMs are even worse(rubbish actually)
If you do not like TW,get rid of the TW launcher only and install whatever you like,the TW framework is the best thing in GS2.
Just do not get fooled by the custom ROM madness,most people boasting their custom stocks/AOSP/AOKP builds know nothing.
There is absolutely no reason to believe that the CM9 will work better than TW in GS2.

I guess you are talking about luca89 ROM (the pure google thing)...I would rather call it a POOR google thing.
Luca actually made a fine GB ROM for GS2 before moving onto AOSP,and the battery life of his new ROM simply sucks(gpu driver issue as usual and luca is helpless as Samsung wont help and he is just a kid to RE the whole damned source code Sammy has dumped)
As you were a Nexus user,I thought you would understand these issues.
Samsung(or any manufacturers for that matter)will never ever give the drivers to the devs and hence the AOSP/CM project will always have the huge mountain to climb.
Remember how much time it took for CM9 team to make the video camera working in GS2(it still sucks compared to stock)??
The CM team after all these years still have the video codec issue,actually the list is pretty long....
And finally did not understand what you mean by root setting!!
Did you try to say fiddling around with su access?

[ancilary]

No not that.
Under volt, over clock, governor etc
Well in my opinion currently I switched to aokp rom only aokp an its good compared to cm9 or cm merged with aokp.
But if you want very stable rom then you have to go to Sammy roms..

[red dragon]

All those undervolting overclocking can be done in stock ROM with a custom kernel.

[ancilary]

Ya but I already mentioned I Don't like touchwiz ;p
Well it depends on their tastr
I like aokp cause for me it's better than those Sammy roms at least for me and I can get any theme for it sense, and touchwiz or what ever

[ajayashish]

So if someone wants to taste RAW ANDROID which rom is best for S2. I like the blue icons and the pure ICS dialer screens and want to use them...

[ancilary]

Cm9 or aokp then customize them to your wish.
Just search aokp themes in market you'll get all kind of themes

Hi Guys,
I got the Titanium backup now and have rooted my S2.

Now can someone tell me how to get the connected contacts backed up. I mean when I sync my phone with Google and also with Facebook, there are multiple entries formed. It took me almost 2 -3 hours to connect the gmail, Fb, and phone contacts. Is there any way I can backup this data so that when I install a new rom I dont have to sit for 2 hours again and connect them. Rather is there a way that when i have a new rom and i can backup my data in such a way that all the contacts are connected already.

[amjath]

I usually use titanium backup for app + data. And kies for contacts, messages and other stuffs.

Do when u backup in Kies does the contacts remain connected when u restore.

Sorry I missed this part what do u mean by connect gmail, fb contacts

u mean grouping

[ajayashish]

So example...

I have a friend, Amit Khanna and he is my phone list

When i Sync with Google his email address comes as Amit Khanna and this is a separate entry in phone book with only email address.

When I sync with FB, I get another entry with some different email address.

So now I have 3 Amit Khanna in my contact list with 2 email and one phone number.

I believe we have an option to connect these contacts as One contact.

Now when i upgraded my phone I lost this connections and has to do the connection for the contacts again. My question is that does Kies or Titanium retain this connections after i install a new rom.

[amjath]

^ sorry dude i have no idea on that connection thing and back up. Someone may help u.

BTW I dont go to contacts [directly to phone and type the name and call] so never faced problem as of now
