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)

Okay, Thanks for the info! I have one more question: What happens when i update my ROM with eg. ROM Manager? Will i need to restore from Titanium Backup there too?

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,
Currently I have a Samsung Galaxy S III with the Android Revolution HD 9.0.0 and I want to upgrade to version 10.0.0 which is the current version. But I dont want to wipe my data to upgrade.
The reason for this is because even though i've backed up everything using titanium backup, I have a layout which I like and lots of other settings.
Is this possible?
Thanks.

Yes you can but if you hit problems you must wipe .
If you are currently running an ICS custom rom and the update is to a JB cumstom rom by the same maker then yes you still need to do a wipe.
But if you did a nandroid backup first before updating you could always try flashing the update without wiping but it could cause problems.
The devs always say to do a full wipe so that there are no problems
Hope this helped

Dont agree other wise we all have wiped phones when JB updates .
>>>>The devs always say to do a full wipe so that there are no problems
Usually they don't say full wipe but wipe cache and wipe dalvik .
Some custom roms will wipe above anyway .
My way on a new rom is to format cache and system in recovery only .
Means i just install on top of my data a new system .
But yes i have Nandroid and TB backup always and yes i am prepared if need be to go back to a stock rom after wiping the lot .
Yes i do flash a lot of roms and no i don't have many problems .

If you want to save your home screen just back up the touchwiz app and restore data to your new rom if you have to wipe

So you say that if I do a backup of all apps in TitaniumBackup and restore it after wipe it'll be ALL the same?
Like I never wiped?
Anyone?

CMIIW, in theory, yes. Although in my experience some apps/games data failed to load. But in most cases it gets the job done after flashing to a new rom, which needed you to wipe everything.
Yes applications go, but the data sometimes ne.Lépe every transition from ICS need to JB, download data again.
And can I restore data only from TitaniumBackup?

Regarding the layout, if you have nova launcher you can export your settings and restore after a flash of a new rom..

Don't have Nova Launcher- didn't like it.
I guess I'll just wipe cache then flash the new version ROM and hope for the best (after backups of course).

You can backup just the apps or apps+data. Therefore you too can restore your data only (if you already have that particular apps installed). Try it mate, titanium backup rules :good:

Yes, I just updated my note 2 n7100 from cm10.2 to cm11. I just wiped cache. and works well.:good:
I have Jelly'Beans' Build 6 on my Note II currently.... I have been toying with other roms, However, Jelly'Beans' build has been the best for me....... I was curious if I flash Build 11 over Build 6, is that possible, or do I have to do a complete wipe and factory rest or can I just flash 11 over 6???
Like wise, I have had several devices and rooted and rom'd all of them. Is there a way that I don't have to redownload all my apps and resetup all my accounts [exchange, hotmail, facebook, twitter, etc....]?
Sorry I swear I'm not a noob!
I would do a wipe, cause u were using different roms, in his thread it says to wipe, get go backup pro in the market, backup everything, restore and ur good to go.. I'm using 11 I think its awesome

I agree that if you have run other ROMs a full wipe and reset is a good idea. I dirty flashed 11 from 10 but prior to that I had always done clean flashes. If you use Titanium backup you can speed the process up quite a bit. When I flash I restore the handful of login-intensive apps manually, both app and data, so that I don't have to set it all up again. Don't do this with system apps, but for things like Twitter, Facebook, etc it has worked just fine a number of times. Also if you use a 3rd party launcher you should be able to back up your settings there too so the layouts persist. Widgets will be lost but those are easy to rebuild.
It sounds like you've flashed back to a previous nandroid backup that was on JellyBeans B6, correct?
I say it wouldn't hurt to try a dirty flash first. If it doesn't work well after, then do a clean flash to B11.
As for your 2nd question, I use Titanium Backup for all apps & data that I don't like to reset and reinstall. So this would be my very first app download from Play.
Dude, you're 5 versions ago. Absolutely FULL WIPE.
No question.

not really new to this stuff, but i am when it comes to the note 2.
props to the guys that put CASUAL together, with little effort other than installing the drivers from the samsung website, a few tries and reboots, 3rd go and it only took maybe 3 minutes to do the work for me.
so, now i am looking for a way to debloat the rom that came with my phone, not ready to jump into the custom flashing yet, but i would like to remove a few things i never use that verizon drops into the rom.
from past experience deleting from the /system/app and /data directories caused issues with stability on my htc rezound.
also one other thought, with the lg enlighten, rebooting with /system as RW would bootloop the phone, the rezound didn't mind at all, how does the note 2 react to being RW?
any suggestions to debloating the current running rom are welcome, i have already had some for custom roms, but more input would be ok too.
Get titanium backup and remove those apps.
Then I'd make a backup and when you are ready to custom flash, get cleanrom. From the sounds of it that is what you are looking for.
that's what i had said before, but eventually i would like to flash a modded rom, but right now i am thinking about just debloating this one, for fun.
one thing that concerns me, has anyone flashed a rom the s-pen doesn't work on?
is that built into the mainboard or a rom specific thing?
wondering so i know to be careful of what i flash, love my s-pen lol

The S-pen is Samsung software that only works on Touchwiz (Samsung based Roms also known as TW) framework, said framework has yet to be ported to AOSP and most likely will not be. It is very rare for TW framework to be ported in a way that works on AOSP Roms.
The S-pen will work on all Roms no matter what but the special features, like pushing the button to make a screenshot, will be there on TW Roms but not AOSP Roms. With Vanilla Rootbox you can make the floating dot show up on the screen when using the S-pen and the other Roms have some implementation of that. If you want to replace some of the features on AOSP Roms you should look into getting GMD Spen Control from the market, also Plasma kernel has new S-pen features built in. It still won't be exactly the same as running a TW ROM but is close enough for me.
All of the custom TW Roms will have full S-pen support just like the stock ROM and in some cases have a little bit extra.

So is flashing a rom done from the sdcard as normal or is it different in any way from a standard flash, new to twrp.
Yup. Just put it on your SD card and flash. Wipe everything but your external card before you flash. lots more to it but that's the cliffnotes version.

You don't have to and you typically don't want to wipe your internal SD memory to flash a rom. From TWRP recovery you should do a Factory rest (which wipes data but not internal SD memory, the cache and the Dalvik cache). After flashing you should wipe cache and Dalvik cache again but not wipe data. To do that go into the Advanced wipe area to only wipe those 2 and not data again.

No, you want to wipe your data in the internal SD, wiping cache and dalvik cache is a dirty flash and is only acceptable under certain conditions.

I corrected my post that yes you also want to wipe data but only from recovery.
What you don't want to do is use a file manager and delete data that way from internal memory. Nor do you normally want to reformat any internal or external memory from recovery.

ok so quick once over, same as the rez, but i only need to do a factory reset and wipe system, caches and flash?
so i can keep internal storage intact no issue?
what about boot?
slightly different from the rez.
just another awesome thing i found for this phone, wondering how well it works and if i could use it to update twrp or maybe even revert to my flashaholic ways with a simple tap and go.

btw, twrp is the most awesome recovery i have ever used, along with titanium backup, which i have never used, i now have a debloated stock rom backed up.
i haven't been this thrilled since i achieved s-off on my rez.

Well I use the second options in TWRP, I can't remember what it is now, under the wipe menu that you have to type yes for that formats the internal memory to get rid of all the BS. It doesn't hurt as long as you know what you are doing. And as long as you only delete old folders that are no longer in use everything will be fine.
TWRP doesn't have any dangerous wipe options at the current moment.

You can use it to update TWRP and download ROMs but I wouldn't flash my Roms from it, you can flash from it but I personally wouldn't. There is also a app named ROM Manager you can flash Roms from but there are a lot of issues when using ROM Manager.
I personally use the Goo Manger app to keep up with my Roms updates.
In TWRP after you click the Wipe button and go to the Wipe sub menu I always click advanced wipe and go in and wipe Data, Cache, Dalvik, and System and then I back out to the Wipe sub menu and click the right hand button, you'll have to type yes for it to work, and that gets rid of all the BS folders and crap so you can start completely fresh. You don't have to do that if you don't want to, I personally like my phone being completely clean when flashing a new ROM.
Yes you can keep internal and boot intact.
All you have to do to go to a new ROM when you boot into TWRP is click Wipe and then slide the little slider in the Wipe sub menu, I believe it says swipe for Factory Reset. That is all you have to do to Clean Flash a ROM.
Something else fun about TWRP is that you can theme it. Here is a TWRP theme collection on XDA:

If you use Titanium to back up apps (which you can do together) and their data before flashing you can restore the apps and data all at once after the flash without having to install each one by one from Google play store. Be sure not to restore system apps or data (no need to back them up either) because it may affect the new rom.
The good part of not reformatting your internal or external memory from TWRP is that your photos, music, etc.will remain after the flash. Even if you choose factory wipe or wipe data in TWRP.

I used titanium backup root to debloat a little, so I am kind of good for now, but made a nandroid of this rooted, debloated stock rom.
I think I found a twrp update with that goo.im app, but I am sure there are more than 4 roms to choose from, I have seen jedi which seemed like what I would want, stock decked out with features and the multi app does all apps, so I am kind of ready to do my first flash.
From what I get from what both or all of you have told me, swipe to factory reset, wipe system and internal, leave boot and others alone.
I wanted to set twrp to save to my sdcard, but didn't see an option to do so.
And thanks for all the input guys.

All you need to do before flashing is the one Factory reset wipe on the first screen of the Wipe area. Just as TWRP advises on that screen. After the flash most go back to the Wipe area then the Advanced area and wipe only cache and Dalvik cache. Your first reboot will take a minute or 2 so be patient.
To save backup to the external card go to the Backup area and at the bottom where it says where it will backup press on it and then you can change the location. It just looks like a label and doesn't look like a button but it is. I would just backup the default checked items. Even that will be 3-4 gigs.

You should also back up the EFS in your first nandroid just in case you ever lose your IMEI or any of that good stuff. Then store that backup in a safe secure space. You won't have to back up the EFS again after the initial backup as long as you always keep that backup safe.

Well Spen with work on all the Roms, the only issue is that it doesn't have all the software features on AOSP as it does on TW. It will have all the same features as stock as long as it is a Touchwiz, TW, ROM. Moon ROM, Jedi, CleanRom (both versions), Beans, MeanBean, Goodness, etc. And you can still add a lot of your stock Spen features back with GND Spen Control.
