i just do this as well.

I don't recommend wiping xloader
don't know what sbl is
and I always thought /boot is for the boot.img(kernel, i.e. needed to boot device)

[Q] what for is /cache partition used for?

On my phone, /data is being used for cache, then what is /cache and what is it used for?
/data is the data partition storing app data and /cache for app cache. Only Dalvic cache is stored in the /data partition.

Hi
I think that "/cache for app cache" is not exact.
App caches, like thumbnails, browser cache and such, as I know are stored in /data/data subdirs or in sdcard.
/cache "should" be used by market for downloading apps before installing them into /data (I wrote "should" because my /cache is never used...), OTA updates and by recovery like CWM.

System wipe

Any way to format the internal storage via CWM?

Not that i know, but you could just lock and unlock your bootloader to wipe everything.

You can. You just need a script that will do it. If you can't find one, I can make one up for you tomorrow.
The other suggestions made will certainly erase you data/settings, but not the rom.

But formatting /system will erase the rom, but not the internal storage?

What do you want to erase? Just the data partition? You can easily do that either by locking and unlocking your bootloader or by doing a factory reset, as was mentioned. If you want to wipe your device, you have to do that with fastboot erase or via a script in CWM.

Basically I just want to make sure that by erasing my system I won't wipe my storage

Your rom is on the system partition (along with anything you install on the system partition via root). Your apps and settings and sdcard are stored on the userdata partition. Unlocking the bootloader erases the entire userdata partition. A factory rest in CWM erases the userdata partition EXCLUDING sdcard. A factory reset in the stock recovery erases the entire userdata partition.

this worked for me:
-in recovery mount data and system
in adb shell type:
cd /sdcard
rm -rf directorynamehere
reboot

Full wipe?

I've done some searches but I can't find details of exactly what is involved in a full wipe.
What constitutes a full wipe?

Also wipe boot partition and possibly other system files stored on sd card other than .android_secure.
If you select the wipe data/factory reset and then wipe all partitions except sd card option it does the same thing. Just be sure to flash something that restores boot partition as having no boot image can result in a "stuck" device.

Install 4ext recovery from www.4ext.net. Boot into recovery, select 'wipe/format' -> 'format all partitions (except SD card)'.
Wiping the boot, system, data, cache partitions & .android_secure folder is what constitutes a full wipe. With 4ext recovery you can full wipe at once using the above option.

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).

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

Guess you'll have to do it the long way then per the instructions above. Let us know how it goes.
Will definitely give it a shot when I have more time! Thank for the help
