Hi I had a quick question.
When I flash between cm9 nightlies using cwm touch recovery I'm always in the habit of wiping cache partition and also dalvik cache. However I've noticed that with dalvik cache it always says SD ext partition not found but immediately after it'll say the wipe was completed. I understand the galaxy nexus is all internal memory but cwm actually wiping dalvik cache even with this error?
Thanks in advance for your answers.

Yes, it's still wiping fine. It's just not wiping a certain partition that we don't have and have no need for. You can be sure Dalvik is being wiped because when you reboot it gives you the "android is upgrading" screen. That's the dalvik cache being rebuilt.
As the GNexus "only" has a row of system memory chips, there is no sd-ext. to be harvested, and filed down.
If, however, the GNexus would have an internal SD, it would have have an sd-ext.
But, as I said, as it is the ROM AND the userdata carrier, and is always mounted, and therefor does not need an ext
Hope I could help!

Recently I've managed to root using Unrevoked and flash a new ROM to my HTC Desire, I currently have Cyanogenmod v.7 RC2 running and it's fantastic!
However I'm already running low of internal memory.
I've done some reading about how to boost this by setting up a partition on my memory card, however there are some things that don't quite add up in my head. Below is a list of what I think I need to do to obtain A2SD+ for Cyanogenmod v.7 RC2, correct me if I'm wrong anywhere please
Make a backup using ROM manager
Copy all important data from memory card as I will have to format it - This includes the backup.
Use ROM manager to format the SD card and create a ext3 partition
Download S2E (Simple2ext) from the android marketplace and tick the box to move the dalvik cache to the SD card.
If the process list above is correct then my questions are:
Do I need to have obtained S-OFF to complete this process?
Do you need to start from a clean slate when moving the dalvik cache, i.e. should I factory-reset/wipe dalvik cache/wipe cache and then install Cyanogenmod v.7 RC2 again?
When you move over the dalvik cache is this a permanent move? For example if I had problem booting and I went through the factory-reset/wipe dalvik cache/wipe cache and then install Cyanogenmod v.7 RC2 again would this reset the dalvik cache back to its original location on the internal memory? Or would something more complicated need to be done to achieve this?
Thank you in advance for any help,
I'm slowly learning the basics

Bump,
any help would be greatly appreciated.
For any tl;dr
I really just want to know if moving the Dalvik cache to the SD card is permanent? Or will a full re-flash restore the dalviks original path back to the internal memory?
1) No.
2) No, don't do anything.
3) The dalvik cache does get moved but not too sure if it's permanent.
I would say to move dalvik cache back to internal, you would have to wipe /system because it's a script that gets installed as you need to remove the script. It's not permanent the way your thinking of. Just if you move it using the script then I don't think you can move it back whilst the script is installed. When the script is removed it will reset and go back to internal. Does that even make any sense?
I tried to manually flash ROMs by booting into recovery. But in order to do that I need to do a full wipe. But I am not sure for this particular "Wipe Dalvik Cache" option. I select it and it says E:Can't mount /dev/block/mmcblk1p2 (Invalid arguments)
But after I press Yes - Wipe Dalvik Cache is says Dalvik Cache wiped. Have I actually wipe that dalvik cache? =/
That's an error normally caused if you wiped data and cache then went onto wipe the Dalvik-Cache manually in the advanced menu.
What you are doing is trying to wipe it twice and it gets confused so throws up this error.
As a general rule you shouldn't need to use this advanced method if you have already wiped data and cache.
Not the best answer but I believe to be accurate.
Just use full wipe 1.3, saves loads of hassle for wiping between ROMs.
Depends on how often you update and change ROMs as has been discussed many times. This question was just asking about dalvik cache.

Oh looks like I am wiping too much. haha. thanks guys!
Will wiping the phone in CWM delete files on the "SD" space of the phone? I've read it is all apart of the same partition, so I wanted to make sure before awkwardly deleting the ROM I am about to install..
I have wiped tons of times in CWR and it hasn't touched the /sd yet. All my files are safe and sound.

Yes, it clears *all* internal storage.
So...which is it?
Maybe I misunderstood but are you talking about wiping /data and /cache? Because when I do this it does NOT wipe the /sd but does wipe all other user data, just like on every other android phone I have had.

Wipe data/factory reset on CWM wipes your WHOLE phone, including "SD" card. I advise you to use the Super Wipe Lite script from the Android Revolution ROM, get it here. This will do a complete wipe, except SD card.
A bit of more info, in case you're interested: the SD card is the folder /data/media mounted as /sdcard. When you wipe in CWM, the data folder is emptied as well.
EDIT: i havent actually tried to do a normal full wipe from CWM, im stating the above just from reading other reports here. Maybe the last version from CWM has fixed this, i dont know
EDIT2: You can wipe cache and dalvik as usual from CWM without any problems.

I figured that was how it was setup, but didn't know if CWM had any logic built into it to filter out the folder. I'll take a look at the script, thanks.
The built-in factory reset in Android will also wipe everything.
I did data,cache,dalvik wipe and formatted system going from 4.0.2 to 4.0.3.
I did NOT lose my SD card
The default wipe in ICS clears *all* internal memory. The default Factory Reset feature of CWM does the exact same thing. I've done it twice and it wiped fully both times.
Very interesting direct contradictions going on in here..
Wiping data in CWM DOES NOT WIPE THE VIRTUAL SDCARD. People need to stop saying it does.. it is all one partition but the virtual SD card is not wiped when you wipe data in cwm.. Factory resets in settings will wipe your virtual SD card but cwm WILL NOT.
Edit: sorry I had a long night, but I will leave the caps so people actually read it.

It is quite troubling to read how many people are saying that wiping in CWM will erase the SD card.
It 100% DOES NOT. I have wiped in CWM dozens of times already. I can not say the same for Factory Reset in Android...but in CWM wiping data DOES NOT wipe your SD.
So I'm just curious here. I never messed with rooting and ROMS with my original Moto Droid, it started with my Droid Charge. I've always adhered to the rule of wiping the 'big 3' when doing a major change. Data Wipe/Factory Reset. Wipe Cache and Wipe Dalvik Cache.
My question is this; when doing a data wipe/factory reset, one of the steps listed during the process is formatting cache. Then when wiping the cache, it does and displays what appears to be a duplicate function it says "formatting cache".
So .... when doing a main 3 wipe, are we actually accomplishing the same thing by just doing a data wipe/factory reset and wiping the Dalvik Cache?
Hmm, if got it correctly then all you need to do is "wipe/factory reset" and "wipe dalvik cache". After doing so there's no need to format cache once again.
/system should be formated automatically when flashinging new ROM, though i do that manually. Justc in case.

I want to install a 4.3 ROM over my 4.2.2 ROM, in the instructions it wants me to do the following:
1. Wipe Data/Factory Reset + Wipe Cache partition. (I have done this before).
2. Mount System + Storage
Format System
Format Data
Format Cache.
(Haven't done this before)
3. Wipe Dalvik Cache (I have done this before)
So my question is what does step 2 do. I am scared it will wipe all my data like pictures audio files etc. that I want to keep.

its alright to format /system, /data & /cache as long as you don't format the /sdcard, i always format /system /data even when i'm just updating the rom .. ^^
Just use factory reset in your custom recovery. It handles data and cache. You don't need to manually wipe system and you don't have to touch dalvik
