Wipe data - Samsung Galaxy Nexus

Before this i am using phone with micro sd extrrnal, so when i full wipe, i know sd not wiped.
So, in gnex, it use internal, so if want to flash new rom, what i need to avoid so data in internal not wiped? Does full wipe erase sd also?

Both "Wipe data/cache" in CWM and "Wipe data" in TWRP excludes internal media (/data/media), so you should be good to go.
CWM is verified on my Nex4 and TWRP is verified on GNex.

factory reset will only wipe system and cash partitions.

Wipe Data - SDcard space too?

Hey all, I'm new to the Galaxy Nexus. When you wipe data does that wipe your internal storage as well? As in the mnt/SDcard partition.

No. Your content is in data/media

In a custom recovery, no. I believe stock recovery will wipe everything.

Yup if you're on stock recovery, it'll delete everything except things like ROM and kernel

Just to add some detail:
When you wipe data (or factory reset) using a stock recovery, it wipes the entire userdata partition (which is mounted as /data in Android). The userdata partition is where all your data is stored included anything stored in /sdcard. [It does not touch any other partition. So if you have a custom ROM, doing a factory reset will not magically restore the stock ROM. Same thing for the other partitions.]
When you wipe data (factory reset) using a custom recovery, it deletes all files in /data except the files in /data/media (which is mounted as /sdcard in Android).

TWRP Question

In the TWRP Recovery, under the wipe menu, there is an option to wipe the system. Does wiping the system in TWRP, wipe all of the internal and external sd card too?

To my knowledge it only wipes the /system folder. There are other buttons in TWRP to wipe internal and external storage.

No it wipes /system

Formatting system

Noob question... What will happen when I format system. What will I lose and keep. Will my internal storage get lost? And will I have to push new rom back to phone via usb transfer. I do understand wiping data, both caches, and system, but what does formatting system do.?

Your ROM is installed on /system. If you wipe system you wipe the os. It doesn't touch the data or internal storage.

Yes,you have to push new rom back to phone via usb transfer!

no. no you dont.
wiping /system just erases the /system partition.
Thanx guys... I think I'm good. System wipe/format system will not erase data. But a data format wipe you lose everything. That's what I thought but wanted to double check so I didn't lose important data.

TWRP wipe

Can anyone confirm the wipe options of newest TWRP ? wipe cache and dalvik cache i know but I am unsure about the "wipe internal storage" and "wipe data" option ? Which option should I choose if i am coming from PA 4.1.2 to 4.2.2 ?
DONT wipe data.. in twrp wiping data will also wipe sdcard.. when flashing roms do a factory reset
Factory reset will delete all the app related data , right ? My contacts, mms , etc will also get deleted ? But the data/media will be intact ?

twrp is alot better than cwm IMO, its faster and it flashes roms better, i am saying this from experiece when i had a s2 i use to have issues with cwm but twrp never let me down..
and most roms wipe system before installing the rom but i wipe it anyway.. this is how i flash ANY rom, even updates of the same rom, and never have issues
1. factory reset
2. wipe system
3. wipe cache
4. wipe dalvik
5. flash rom
6. flash gapps
7. flash AK kernel(optional)
8. reboot
9. wait 10 mins then do another reboot
10. enjoy :good:

Thanks again, for updates for same rom u also factory reset ? That means every time u setup your apps, contact , mms ? That would be painstakingly time consuming .
There are apps that can back up your apps and app data as well as text messages. Its not that time consuming. Some launchers can backup layouts, too, so that cuts down on having to reset your home screens. Contacts can be synced with your Google account, unless I misunderstood the contact comment, so much like your email they are synced when you enter your account details.

This is pretty much the formula I follow.
1) Wipe cache
2) Wipe Dalvik (a little redundant since dalvik resides in /cache)
3) Factory reset
4) Wipe System (like said above, most ROMs wipe /system but I do not anyway)
5) Flash ROM
6) Flash GApps
7) Flash kernel of choice
8) Fix permissions
9) Reboot
10) I immediately install Titanium Backup and batch restore all apps and app data before signing into my Google accounts
11) Reboot back into recovery and fix permissions again
12) Wipe dalvik again so everything is optimized
13) Reboot
14) Set up ROM how you like it.
The other thing I do is copy Nova Launcher into /system/app and get rid of Trebuchet.apk or Launcher2.apk as well as live wallpapers and other things I consider bloat. Nova let's you back up all your configs and settings so I just restore that. I'm usually back up and running in 30 minutes or so, I could pretty much do it in my sleep...

I 100% guarantee you that a factory reset will leave your sd card intact, I do it every day almost. The only way to nuke your internal storage is to wipe data, which nukes /data/media (basically your sd card) and pretty much everything else, or wiping internal storage will also nuke your sd card...

If I remember there are two options in TWRP , one is wipe data and wipe internal storage , so both do the same work , nukes data/media ? So what is the point of keeping both of them ?

Internal storage nukes just the sd card, wiping data nukes all internal storage, sd card, system, etc, if you do that you basically have to flash a stock image with fastboot...

I have never tried the factory reset option with my GNEX, but using it on a Galaxy S or Galaxy Ace definitely erased the entire internal storage. It would als mean the factory reset warning is incorrect. Strange stuff.

If that is the case then I think the nomenclature is pretty confusing and misdirecting ,
factory reset = only app related data and contacts and mms
wipe data = everything including system also
wipe internal storage = data/media.
As far as I know the factory reset option in the rom itself nukes the data/media and app related data also , what in the case for recoveries are different .Wipe data option shouldn't be there in the recovery as it can be pretty dangerous if someone accidentally does it.

If I'm not wrong, wiping data means that u have erased your current ROM, and you need to reinstall a new rom.

Wipe t999

I flashed route 66 4.3 update via Odin last night, however I would like to do a clean install. How can I wipe the internal memory so I can re-flash via odin? I'm trying to remove all apps etc. Any help would be greatly appreciated

There is a script that can be flashed through a custom recovery that will completely wipe your internal memory clean. I have it on my S3. I'm on my nexus 5 now so I don't have access to it right now. If someone doesn't have a better suggestion I'll share it with you when I can.

Go into recovery and format /Data. If you are on TWRP, there should be an Erase Internal in the Wipe settings. Not sure about Clockwork.
Boot to recovery.
Wipe /Cache
Wipe /Dalvik-Cache
Factory Reset.
Format /System
Format /Data
Profit!!!
In recovery Format Data =/= Wipe Data
Format is erasing your internal
Wipe is wiping your app data.
Edit: If you want to flash what Jorge said above, just search for XquiziT's Superwipe and you might be able to find it.
superwipe doesn't work, i get an error and reboots back into 4.3
