Do they actually delete any physical data?
Whats the differences between the two really?
Please advice
with friendly greet
The cache partition stores temp data and downloads from the market and htc hub. And the dalvik cache is created by the dalvik vm, its used so android can run apps with optimal bytecode. If you wipe the dalvik cache, the dalvik vm will rebuild it on boot

grrr ... first time i dont do a full backup before updating and im stuck on the boot animation .... not rebooting, just the animation going on and on and on ... waited 20 mins before taking the battery out. tried several times and managed to get into android but then SPB hung on a blank screen and i couldnt do anything !
battery out again and tried reflashing (again) - this time wiping the cache first ... 10 mins and still boot animation
anyone got any thoughts before i give up and revert to a month old backup ?
ignore - wrong thread ... ADMIN remove ?

I'm wondering how often i should delete Dalvik Cache, is it something that people do regular or only occasionally, and does it matter,etc?
Thanks
You should wipe the dalvik cache , along with the partition and data,just before installing a new ROM .

Hi Jonny,
When installing a new ROM and you don´t delete the cache, and I do a factory reset, along with repartitioning my sd card, there will be old stuff left over from the old ROM. So when we talk about a clean flash, that´s what we mean.
So is it recommended i only delete dalvik cache only when downloading / updating a new build?

Yes only delete the Dalvik cache befor you flash a new ROM,check my guide I have linked in my sig to get a better understanding what the Dalvik cache is and it's function, well at least a good general understanding of it.
I personally always run a Task 29 and then reflash MAGLDR and CWM then my room just to be extra sure.

Hey guys just a quick question about installing nightly builds on the nook. When Rom Manager asks whether to wipe data/cache and what not, if I select it, will it wipe the internal memory completely? leaving no user files behind? or will it only wipe the system files?
It will wipe everything and it will be a fresh install.

If you update, just wipe cache
It wipes the /data partition but doesn't wipe /sdcard /sd-ext or /met/emmc.

Note: wipe cache and wipe Dalvik cache are 2 different things.
+ wipe cache is a quick way to clean the current running ROM
+ wipe Dalvik is a completely clean.
After wipe Dalvik, next time it boots, it will take a lot longer time due to the device has to re-compile the whole thing before ROM start running and booting.
I think I need to drop a few lines about wipe cache/Dalvik.
As I posted above, I said it wiped clean.
Apparently, I am NOT 100% correct.
I just updated to nb198, wiped cache (formatting /cache) then wipe Dalvik cache.
After done updating ROM, booting up, I expected everything clean, completely fresh.
It's not the case, I went to Market and all old search history were still shown. Not only with Market but other apps too.
So
a. either wipe cache/Dalvik is NOT completely clean wipe or
b. it was completely clean but somehow, those old cache info, which stored somewhere I don't know, get automatically restored back.
Okay, I did a quick read of the FAQ for CWR, and came across these:
Wipe cache partition
Wipes the cache partition of the device to clear all the data accumulated there over use. This is often used before installing a new ROM, app, kernel or any similar mod via recovery.
Wipe Dalvik Cache
Allows you to wipe the cache for the Dalvik virtual machine (the custom-built Java virtual machine for Android).This is required before most ROM installations and at other occasions too, for fixing some problems.
So, I'm taking this guide on board and will wiping Cache AND Davlik. So that's two steps prior to installing a new CM7 nightly build.

You didn't happen to store them in uSD card? Or perhaps app data/cache are separate from system data/cache...
Will look into it further...
I changed system partition size on my gt540 to 220mb to use ICS. But when I restore my backed-up ROM(CM7) it sticks on boot logo or restarts over and over.. changed my system partition back to 150mb still same problem and ICS still work . (system partition didn't change)so I cant change my partition anymore?!
Did you wipe cach and dalvik cach after restore?

Recovery , advanced , wipe dalvik cache
Sent from my Optimus
gonna give it a try
EDIT: worked thank you very much
I had no problems with my Defy (CM7.1) until now.
Whenever I open "Gallery" Defy takes too long to load the pictures. I get to see a blurry/pixel-ated version of all my pictures. It takes way too long to load the actual preview of the pictures. Once I close the Gallery & kill it via Task-Manager my phone hangs. I have to reboot the phone by removing-reinserting the battery. This is getting annyoing!
Are/Have any one of you face similar issues? How do I resolve this?
Please help!
Try increasing vsel or formatting cache and dalvik cache
Sent from my MB525
How do I format cache & dalvik cache?
Bumping it up...
Boot into recovery mode, select custom/latest recovery. There is an option to wipe cache partition (not the wipe user data/factory reset) and then go to advanced, you will see wipe dalvik cache option there.
