Hi all
I have had my Galaxy S II for about a year now, and i am thinking about rooting it and installing Cyanogenmod on it, but i need some info about the proccess: First of all: What happens when you root your phone? Is you data/apps deleted or is it safe?
Second: What about when i flash Cyanogenmod? Is my data/apps safe there or do i need to redownload the apps and backup my stuff?
Third: If i root my phone and do not flash a new ROM, will it be just as hard for me to update the firmware as on a jailbroken iOS device?
And lastly: I have heard about Titanium Backup, what does it backup? The OS, the apps and/or the data? These are the questions i need answered before starting the rooting proccess
Thanks in advance

The process is a little different depending on the device but basicly a super user binary and SU app are installed on your device, this will not (in most cases) effect your data or apps.
When you flash a new ROM like cyanogenmod you will loss your data and apps yes so you will need to redownload/reinstall them backing up using a app like titanium backup is recommended.
In most cases if you root your phone it will not be any harder to update the firmware however after the update you will loss root, and often the hacks used to install SU and a custom recovery get fixed in newer updates, so its normally recommend not to update through the official process but to flash a modified version of the update normally found in the XDA forum for the device, these modified versions will have super user etc preinstalled so they cant be lost during the update.
Titanium Backup backs up your apps and there data (so when you reinstalled them with Titanium Backup it will be just how you left it)

if your upgrading the same ROM to a newer version for example if you where on CM9 version 1.0 and updated to 1.1 you will likely not have to no, however the developer will post if the update requires a wipe, as some large updates do need a clean install.
If your going from one ROM to another than you will need to wipe yes

Hi!
I want to get rid off some apks (see title) with titanium backup.
The problem is, that those apks are listed as service, so titanium backup only backups data and not the app itself. So there is no way to restore?
Is there a way to restore these pre- installed apps after deletion (maybe I change my mind ).
TIA,
Caveman
I'm sure Layar is avalible on the market, so is the CarHome. LG App advisor is crap so you can forget about it.
Copy the apk from /system/app. You can do this by mounting the system partition as read and write, then cp the apks to your sd card
So there is nothing other than the apk?
Why does titanium backup delete these apks without backing them up?
Thank you,
Caveman
By the way, I haven't tried this yet with a ROM that hasn't been deodexed. Backup both (.apk & .odex) just to be sure if you're in a stock rom.
Regarding titanium backup, I have no idea. I backed something up and uninstalled. When I tried to restore, it won't. The option is grayed out
EDIT: Just in case --> http://theandroidsite.com/2009/11/2...and-paid-android-applications-for-root-users/
Ok, thanks.
BTW: First attempt to restore stock rom (if I saw that titanium backup did not backup LG's "services" it was too late ) went bad (the phone stayed in "emergency mode")- that just increased my heart rate . The second attempt (without LG's modem drivers) went well
Thank you all!
Good luck with the stock ROM restoration Btw, I just want to suggest that you don't use KDZ flasher to restore to stock firmware. If you already have a custom recovery installed, just flash another ROM over the one you want to replace.

What do you mean? If you mean flashing the KDZ from the custom recovery, I don't think you can.
Here's a handy list of custom ROMs we have in the site (at least for the O1):

It sounded like you could flash stock rom with custom recovery...
I noticed that there are a lot of custom roms available
So, thank you again,
Caveman
Sorry about that. How I talk/write can be confusing at times xD But yes, you can install the stock ROM with custom recovery, just not the .kdz file. From that KDZ file you can create a zip to flash using custom recovery.
I think the main reason why people revert to stock firmware (ROM + stock recovery) is because they have to take it to a service center and they still have their warranty. Or if they badly need the factory stuff xD

I wanted to reply to this thread: http://forum.xda-developers.com/showthread.php?t=1159920 but I only have less than 10 posts which is a bit annoying as I want to ask about that firmware. Is there a way to backup everything, like angry birds save game and other save games before ROM flashing? I am using a stock SGS2. Titanium backup only works on rooted phones. I am not sure if Kiess allows me to do it. I notice there is a new firmware in Kies as well:

My Backup Pro doesn't need root but I can't tell you for sure if it will backup everything as good as titanium backup does and more important restore it correctly.

i dont think so, at least not for everything. basically its best to root a phoen immediately when you buy it, becaues rooting needs to wipe the phone just once. then after that you can backup all day long and wipe as many times as you want, flash many different ROMs, and always restore your backups.
but that initial root always needs a wipe first. so its really better to not get invested in the phone until you root IMO.
basically, I need to replay all those angry birds levels again...

quote from Chainfire's CF-Root thread:
THIS IS NOT A ROM - it is only a modified kernel. You need to have the relevant firmware already on your device. You do NOT need to wipe anything for this patch. You DO need to read the instructions. PLEASE READ THIS ENTIRE POST!

For Angry Birds specifically there is apps that lets you back up and restore the progress. I use ANTBEE AngryBirds Backup. There is one for original one for seasons and one for rio.
With it u make a backup, u copy the files it create to ur pc or somewhere safe, when u reinstall angry birds u have to play 1 level on each version of the game then backup, after that u replace the new backupfiles with the old ones then press restore in the app, voila everythings back!
As for rooting with cf-root u wont loose any apps or data when u flash the rooted kernel, u can also flash back to original kernel after and keep root.
Mybackup pro will not backup saves and progress from apps unless ur rooted.
I just did a backup with Kies and all my data is intact. Update from KE4 to KE7, but still android 2.3.3. I am not sure if it did wipe out the phone data while updating the firmware.
Hi Guys,
I'm new in the android world and exploring around with custom roms. however i want to return back to a stock rom. Now i was wondering how can i do that without loosing any of my data e.g. sms, photos, save game data etc. can i return to stock using the same method going into a custom rom, using CMW just wipe dalvik cache and install rom? and will this also flash my kernel back to stock as well?
After returning to stock i will just root that and flash counter isn't an issue i have purchased Triangle Away
Thanks
You can`t, you can however copy your files to your pc and place them back after the flash.I`am using Appmonster pro to restore apps from sd to restore my apps if i`am not rooted.
You can also flash a stock rom and still keep root with MobileOdin Pro.

If you do a system upgrade it`s best to to a data/factory reset and wipe cache and dalvik cache, you don`t have to but it may result in crashings apps and system components. As fot the sms i don`t know, look in the playstore for an app for that. If you want to stay rooted backup users apps with Titanium Backup. and restore them after the flash, don`t know if texts are restored however.

ok so basically i want to find a way to get to 4.3 either rooted or unrooted, my problem is that i have pretty bad ocd and one of my major major problems with that disorder is my tech devices, i will most likely have an anxsiety attack or 2 if i have to set up my phone from scratch and i will spend hours making it look exactly the same. anyway, i want to know:
1:how to update rooted gs3 Gt-i9305t 4g/lte model without loosing data (if possible )
2: update to 4.3 and un root without loosing data (im sure thats impossible )
i would really appreciate the help as i cannot find anyone looking for the same help as me (kinda strange how no one cares about there data at all, but meh)
also on a side note, i have the problem with my s3 where any sd card i put into the machine will eventually kill itself and never work again as far as i know, it has killed 3 32gb sd cards now and its starting to piss me off to the point where i am no longer using an sd card at all. why does the phone do this and is there any way to fix it? either software wise or hard wear wise? thanks !!! :fingers-crossed:
4.3 source code has only just been released. 4.3 roms are not fully functional and have bugs. There are no official releases so they are all "rooted".
You really do need to wipe when making version updates. Theres no way around this.
Stick with what you've got.
that just sucks.

hey another quick question, is there a way to so a full backup, like im talking FULL, like down to the point of where ur apps are placed and all there data, like apple devices have through itunes?? (restore from backup option) cus if so then i dont mind wiping at all, i just hate apple so i will never go back to one of there piece of **** devices again (i like features with my shiny brick) but yeah anything like that? or can kies do that?
i'm using temasek 4.3 preview 3 atm, you should check it out since developer is extremely helpful
and he updates regularly (which is important)
There are a number of ways to keep your data. Including ones that will let you change the ROM and still have your data. Titanium Backup - not sure if it is only Pro version but the one I have lets me create a backup on the extSDcard so I can flash it in a new ROM and restore all my apps and data straight off. SMS Backup and restore and Call Backup and restore both save out your data to the extSDcard so you can bring them back. I used to use My Backup Root as well but it ceased to work on the last update so I nuked it.
Add in a nandroid backup on something like Philz Recovery (where you can do an Advanced Restore from External SDCard and bring back just parts of your current ROM) and you can always get back to your look & feel in any new ROM.
The one thing I ahve NOT found a solution for is replacing my widgets back on the screens they are on - I run 7 screens and it pisses me off a full recovery in something like Titanium doesn't restore my widgets. The only way it happens is a full nandroid restore but that nukes the new ROM I have just installed so that's not an option.
I run Purelook HD as my 1st ROM, GoogyMax kernel and SlimBean as my 2nd ROM. I can nuke either or both and be back to my set up (including widgets) in about 45 minutes.

Lets dissect this a little.
A Nandroid backup will take a snapshot of your phone. If you flash something wrong, it can be used to restore your data / settings and rom exactly how it was. This will not help restore your data and settings on a new ROM where you had to perform a wipe. (You have to perform a wipe to prevent data and settings incompatibilities with the new ROM that will cause problems.)
Titanium backup is great. However, if you had to perform a wipe, you cannot simply restore everything using Titanium. This is because you will be restoring the incompatabilities (System data) and restoring the problems (negating the point of the wipe in the first place). You can restore user apps and data with titanium but there will be an element of manually setting all your rom settings.
OP - Please read the "Read before rooting" thread in my signature for more info.

The Advanced Restore in Philz lets you restore Data. The choices are, Restore Boot, System (+or- reload) Data, Cache and sd ext. The Data restored my latest personal stuff from the BU I tried just before a new ROM experiment. So not all Restores are the same. You don't have to bring it ALL back from a nandroid.

@Journyman16
You seem to be missing my point.
If you can restore just data via recovery (which you can) then you didn't need to wipe in the first place.
ROM goes in /system. We all know that. Our apps go in /data/app. We all know that. Our data for our apps goes in /data/data but what some may NOT know is that /data/data contains all your system data too. When you set a ring tone or wallpaper, its in /data/data.
If you go from 1 ROM to another, you may not have to wipe. Or you may HAVE to wipe. It depends if there is incompatible system data in /data/data or not.
When you do wipe, you wipe /data/* (includes /data/data). If you nandroid restore /data and your phone works perfectly, you didn't need to wipe. So my point remains.
If you HAD to wipe, you cannot simply restore data via recovery and have a fully working phone.

I already told you who said there is an update for my phone. Unless my phone is disguised as some one of a kind phone, I'm supposed to be able to update to 4.3.
I've backed up all my contacts, SMS, etc, everything except apps and app data.
I'm gonna upgrade to JB but first I need to root to backup my app data.
If I follow method 3 on this thread: http://forum.xda-developers.com/showthread.php?t=1285894
Will it delete all my app data?
If it will, should I just use Samsung Kies to upgrade the firmware to JB?

Rooting will not change or delete any apps or data. Rooting simply gives you access to the root of your phone, allowing more control over your phone. personally, I recommend framaroot, a one-click app to root the i777 (and many other phones).
Once you're rooted, I would recommend getting titanium backup, which would allow you to:
backup all of your apps and their data.
backup sms & mms & wifi data & ...
get rid of system apps that you don't want or need.
...and a host of other awesome items.
I don't know whether how updating to JB through kies will affect your app or system data, but I'm fairly certain that it won't keep much of it.
Yes, I know rooting my device will not delete apps or apps data, but that't not exactly what I thought I was asking.
I linked to a specific method(method 3) in a thread(http://forum.xda-developers.com/showthread.php?t=1285894) which says that I would need to flash binaries to version UCKH7 in order to root because UKK6 cannot be rooted by SuperOneClick. So basically by asking about rooting my UKK6, I thought I implied that I would be flashing binaries.
So really what I'm asking is if flashing binaries will delete my apps/app data.
But, I noticed you suggested I use framaroot, that looks like a new development but I have version UKK6 where there seems to be problems, will it work with my UKK6?

a dirty flash MIGHT retain your apps and data and still boot, but IMO dirty flashing isn't worth the trouble down the road.
When flashing firmware, it is good practice to start from a clean slate (wipe data/factory reset), which means intentionally clearing the data that it seems you're trying to preserve. I have recently learned that some custom roms even contain their own scripts to conduct additional housecleaning to ensure a bug-free install. To avoid the permanent loss of your data, I suggest using titanium backup to save all user apps and their data, wifi data, sms & mms, (and more) and then safely restore them onto the new rom.

I trust the framaroot compatibility list, which includes the sgh-i777. I have not used framaroot with uckk6 to verify whether it works or not.
@ProbableDesigner,
The rule of thumb is always perform a wipe data/factory reset when changing base. So, flashing UCKH7 over UCKK6 would require a wipe.
You're correct, framaroot was not around when that guide was written. I'm pretty sure I remember someone saying it worked for them on UCKK6. But if it doesn't work, it will not do any damage, so I would suggest try it first and see.
Oh I see, Ok, thank you cyril279 and creepyncrawly. I did not know that you should wipe before flashing.
Also, wow, I did not expect a response from you creepyncrawly I thought you would have disappeared from the forums since you posted the guide so long ago, but it's good you responded since you created the guide, it helps put my mind at ease.
I'll try framaroot and see if it works, thanks again.
