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 Every ROM I've seen recommends wiping when you first install it (many will let you upgrade to a newer version of the same ROM without wiping).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?
I'm new to the GNex. All of my previous phones had SD cards so whenever I flashed new ROMs on it, my music and photos would be preserved.
So if I were to run backup on CWM, does it backup the entire partition or does it just back up the system files? I usually flash/update every few weeks and I'm just prepping myself so I don't accidentally wipe my pics and music....
Thanks!
it backs up everything except the symlink /sdcard

Doing a backup with cwm will not save sd
Using cwm to wipe data/factory reset will not wipe sd

Saves everything associated with your ROM. Not your personal SDcard data.
Thanks for the replies.. Still a bit confused.
After creating my nandroid backup and then hitting wipe data/factory reset, all of my media files would be deleted. Once I install the new ROM, those MP3 and pics would no longer be there, correct?
If so, how do guys deal with this? Do you just end up resyncing everything once the new ROM is installeD? It seems like a hassle if one's media library is huge...
No. Flashing between new roms does not touch the pics and music on the SD card. So you don't lose anything when you flash roms with Cwm.

I thought that's only true if you flash without doing "wipe data/factory reset."

No don't believe so. Wipe with Cwm should keep the SD card in tact. I've done it for a few flashes now...
THanks! I'll give it a whirl!
I would HIGHLY recommend that you back up your SD (Internal), just like you would back up anything else you care about and don't have a secure copy of!
I'm a noob but I flashed AOKP Milestone 4 today and prob'ly did an extra wipe somewhere but my SD was blank, thankfully I had all 2,000 songs and thousands of images backed up. (in several places).
BTW, I love the ROM
When I'm flashing a new ROM, I like to install it as cleanly as possible. Usually a factory reset along with wiping cache and dalvik. Doing this, I know my sdcard contents will remain safe. Does wiping system in TWRP wipe out my sdcard as well? If not, I'll start doing that as well. If it does, I guess I won't.
no, only /system.
only time your SDCARD is wiped is if you choose format /sdcard.
No. Wiping system wipes /system. Wiping internal storage wipes the internal storage. The two don't cross at all.
Thanks a lot, both of you.
For giggles, what does wiping system do? Obviously wipes system, but I mean in terms of flashing a new ROM. How is it beneficial, I guess is what I'm asking.

it makes the /system partition is clean so there is no remnants of the previous rom.
most rom installs include a script that wipe it, so generally its not needed.
You will also lose the contents of /sdcard when you lock/unlock your bootloader. (root)
I do literally everything except wipe external SD.
Even Format Data.

For the record, his bump on the 5 month old thread helped me, over two years later.
Thanks everyone.
Thanks
It is Still helping people like me...Thnx...Keep Bumping
Same
Can confirm... Keep bumping
Hey Guys
Yep
Very useful. One up from me as well. IS TWRP only way to do FULL WIPE or are there alternatives? For example, can this be achieved without being rooted?
bump LOL does wiping the ext_sd actually wipe the data or is it still accessible via linux? im hoping that it only deletes the data table
nvm, it only deletes the data table. Data recovered, crisis averted
I know this is now 4 months old, so using twrp system wipe- wipes out the current android firmware too or no?
If you just want to delete everything from Android SD card , you'd better use eraser tool to do ,
Once you use it to erase your Android SD card , all of the data save on the SD card can be completely deleted ,

Bump, thanks for explain
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.
Hi there, apologies if this is a silly question. I'm not an expert by any means, just a guy who follows the directions given on helpful sites like this.
I recently flashed the Slimkat ROM onto my n7100 for various reasons. But when I did, I obviously didn't completely wipe everything (which is what I intended).
Because for example, I installed a couple games on there and found that my game-saves were still there, also there were some bits on the obb folder from apps that I had on my phone previously but haven't installed since flashing the new ROM.
Why is this? Did I maybe miss a step when flashing the ROM? I know I did the 'wipe and restore factory settings' part in CWM, but I'm not 100% if I did the part with wiping the dalvik and cache etc.
Would that be the reason?
And If I want to give my phone a completely clean wipe what's the best way to do that now? Would I have to go through the steps as if I were flashing the ROM all over again? Or could I just go into recovery mode and wipe the dalvik, cache, system, data etc and reboot?
P.S. Yes, I know that no one who gives advice is responsible if I brick my phone.

Just a follow up - I did a wipe + factory reset, wiped cache partition, wiped davlik cache, and was surprised to find I still had leftovers on my phone. For example I had some episodes of a tv show in my downloads folder and also there was still app leftovers in the obb folder. Meh... I'll just delete stuff manually.

Well, you will have to flash stock recovery then. after that, wipe data/factory reset and wipe cache. This will erase everything on internal SD card. I assume u have backed up EFS and other important stuff.
press thumbs up if u find this suggestion helpful.

By the way, I sort of overlooked the obvious - in the end I just did a factory wipe and reset from inside Slimkat i.e. not via recovery mode.
And that did the job fine. Cleaned up several gigs worth of clutter which apps like SD Maid seemed to have skipped over as well.
