Hey there,
Running CM10 on an AT&T Galaxy S3 and I want to wipe my phone to reinstall a fresh copy of cm10. Haven't done this too often so my question is,
In CWM, is it enough to simply Wipe Data/Factory Reset to achieve a full wipe, or do I need to format the phone? If I format the phone, would I need to re-root it again?

Sorry for the noob question, but, yeah will loading a rom wipe my phone?
Also I was wondering if any good overclocking/undervolting roms have been realeased yet for the GNex?

In short, yes, it will. Merely unlocking your bootloader, which is step one if you're on a stock GNex, will cause your phone to be wiped automatically. After that, it's possible to install ROMs without wiping, but it's a bad idea since there's no guarantee that roms A and B are 100% compatible with each other. Every ROM I've seen recommends wiping when you first install it (many will let you upgrade to a newer version of the same ROM without wiping).
I unlocked the bootloader day 1.
on a related note: when you wipe to install a new ROM, will it wipe the entire phone storage (like when you unlocked the bootloader)? when I unlocked my bootloader it wiped everything off including my music, pics, ringtones, etc.... if that happens everytime than i might just stay away from installing new rooms and stay stock w/ root

When you unlock your bootloader, it will wipe your /sdcard/, but when you "wipe data/factory reset" it will leave the contents of the /sdcard/. So you should be able to keep your images and such, but you'll have to reinstall your apps. TitaniumBackup seems to work well enough for this. It backs up to your /sdcard/ but I still copy it to my computer just to be safe.

On my N1, when moving from one rom to another, I wipe Data, Cache, and Dalvik. Would I do the same on my GN and if so would the virtual sd card be left untouched?
If so, that would be great!

I haven't wiped cache or dalvik (dunno if I was supposed to, but so far it doesn't seem to have created any problems) but I believe that doing the above will leave your virtual sdcard untouched. After all, it has to be able to read the new ROM from somewhere, right?
Okay, I was on AOKP M4 and I wanted to upgrade to M5.
So I backup everything and make a backup of my ROM. I wipe the phone and caches and flash M5 with the GAPPS, with the latest CWM touch recovery. When my phone reboots I notice I have the same wallpaper as before and when I unlock my phone my pin is still requested and all of my apps and settings stayed exactly the same. I was never asked to sign into my Google account and the start up/set up screen never came up. I checked to see if I even updated and yes I was on M5. Now the ROM isn't very fast or smooth and I get a lot of force closes and things not working properly.
I tried the whole process again with the CWM non-touch recovery, and again my phone did not fully wipe and all my apps and setting remained exactly the same.
I tried it again with the TWRP touch recovery, and again my phone did not fully wipe and everything was the same and my phone remains kind of slow and I'm getting a lot of force closes.
Why is my phone not fully wiping? What can I do to fix this?
I would really appreciate some help!
you need to wipe factory / data.
wiping cache and dalvik doesn't wipe "/system/etc etc etc"
1. Wipe Factory
2. Wipe Data
3. Wipe Dalvik
4. Flash ROM
5. Flash Gapps.
6. Flash Kernel
for full wipe.

Yes, that is what I'm doing. I'm wiping factory/data and I'm still having the same problem
Like with the TWRP recovery, I went to wipe, I hit factory reset, then cache, then dalvik cache and then flashed the ROM and GAPPS and all my apps and settings stayed the same. It was like if I had dirty flashed it. I don't understand what's going on.

***FORMAT /SYSTEM*** (under mount in CWM I believe)

What does that do exactly? Would I have to worry about my media and sd card being wiped?

Okay thank you, I guess this time in TWRP I'll do factory reset, cache, dalvik cache, and system and see if it works out
Okay, so I did factory reset, cache, dalvik cache, and format system.
I flashed M5 and GAPPS, rebooted and everything was still the same. My phone did not fully wipe.
I don't understand what's going. I'm so frustrated right now

I would do a factory reset, if that doesn`t help flash a stock rom and root your phone again. BTW don`t you have a nandroid backup to revert to

I have a nandroid backup, but that doesn't solve the problem of my phone not wiping.
I guess I'll unroot my phone and lock the bootloader and re-do everything to see. I don't understand why my phone isn't wiping correctly.
sometimes cwm just doesnt work with factory wipe. i've used it a few times now and sometimes it works and sometimes it doesnt. i have no idea why. you can try doing a factory wipe from the phone settings>backup and reset. ive only done that twice but it worked both times. if that still doesnt work just go with a fresh flash of google images using fastboot.

Init.d folders can only be wiped with a factory reset afaik, or manualy off course. By locking and unlocking the phone you perform a factory reset anyway, so i would flash a stock rom and start fresh. No chance on left files or scripts. You can do it with GNex Toolkit, option 8. Put the downloaded and not extracted .tgz file here C:\Galaxy Nexus ToolKit\put_google_factory_image_here and flash.
Thanks guys, I'll try that!
Just got a T999 GS3 today. Already rooted and installed TWRP. I do not have an External SD card, so I will be putting the ROM that I want to flash (CM10 Stable) on internal SD card. But since I have to WIPE everything before I install the Custom ROM, how do I make sure that I don't wipe the custom ROM install zip as well?
Do I just do a WIPE of cache, dalvik cache, and system? And make sure that I do not wipe internal storage?
Or is there something else to this?
Thanks!!
Do a factory reset wipe system then wipe both caches install ROM wipe both caches again and fix permissions you should be good.

No, there is a seperate option for that.
1. Factory reset
2. Flash ROM and various files
3. reset dalvik cache and cache
4. Reboot
Easy as that
Which method you followed to root? I just got the phone and look ing for the easy way to root. I heard a lot about lost the IMEI so I'm kind of worry
Thanks all. I'm now running CM10 stable and all seems to be well.

I actually used this method: http://www.androidrootz.com/2012/10/how-to-root-galaxy-s3-on-mac-osx.html. It worked fine and took about 20 seconds. I then used Goo Manager to install TWRP, and then I installed CM10 and Gapps. Whole process took literally about 10 minutes. Wasn't even aware of the IMEI issue prior to rooting. I will have to remember to backup my IMEI sometime today.
1. I stupidly selected "format /system" in CWM in preparation for flashing a new ROM.
2. Soft bricked my phone, put new ROM (slim bean 4.3beta) on SD card and flashed it successfully.
3. Everything works great, I still have CWM and slimbean is awesome but, I don't have root access. I don't know how to get it without reflashing everything (and at this point I don't know if that'll do anything)
Is there a simple way to permanently re-obtain root access? Thank you.
If it's a 4.3 ROM you'll need to flash chainfires newest su , don't have the link but you can find them throughout xda or Google search
Making the iPhone jealous one user at a time.
You can also go into settings development and enable root for apps and add on 4.3 the usually just add is enabled when first flashed on 4.3

I don't know why formatting system would soft brick? I always wipe data/factory reset, wipe cache and dalvik, then go into mounts and storage and format system, data, and cache, just to be sure of a super clean install and I have never had an issue??

I'm not totally sure about it either to be completely honest. It was confusing so I just put a new ROM on my exsd and went ahead that way.
Is there a way to really wipe my phone good like do a DoD wipe of the whole OS and all and reinstall the Kernel and ROM from scratch.
I dont care to lose everything I have all my important stuff backed up.
I did a DoD wipe of my external SD Card and loaded a new rom
cm-10.1-20130217-UNOFFICIAL-i927
That should wipe it.....right?
CWM 6.0.1.2 has the format option but i believe its just a simple wipe.....wonder if there are other option with other CWM's?
As far as I know, you can wipe data, cache, dalvik, internal & external storage as you want... But you can never wipe boot (kernel). Only by installing a new one can you overwrite the old.

Thats what I did but it's just a simple 1 write zero pass
Is there a way to do a secure wipe such as gutmann or DoD?
Also, what is dalvik, I have a custom kernel and I am running 4.2.2 CyanogenMod
Baseband i927uclj3
Kernel - 3.1.10-LiteKernel
I'm pretty sure if you do a complete factory reset from Odin or kies it will do the trick. Never had to, though.
