[Q] just a simple question - Nexus S Q&A, Help & Troubleshooting

using CWM 5.8
what kind of files does (wiping delvik cache) delete?
and what would happened to the device after formatting "system/"
last one about ULTRAGEN V.1 ROM
thread link http://forum.xda-developers.com/showthread.php?t=2020137
i followed the instructions carefully but the rom wasn't successfully installed so i flashed CM 10 again

Wiping the dalvic cache did just that, it wipes the dalvic cache... formatting system deletes everything in the /system folder which will require a new rom to be flashed

question about wiping

quick question, im new to rooting the transforner and i just want to know, when i wipe to install prime will it erase my music that is on the internal storage? If so, is there a different way to wipe to keep certain files? Cause i also have my titanium backup files on internal as well, thanks in advance.
First of all, your title made me laugh for a good 1 minute. Somehow, "question about wiping" just doesn't sound very technical and sound more like it has something to do with our bodily functions.
No, "wiping" cache and data will not touch your files. Android is different than windows. Windows OS has 1 big partition where everything is in there. Android has 12 partitions, each one has it's own purpose. When you wipe the data partition, what you're really wiping is app data partition. There is also a user data partition where all your files are kept. Unless you do a format of your sdcard in the advance menu, all your user files are safe.
So, before you install a custom rom, make sure you wipe cache and data/factory reset. Also wipe dalvik cache. Trust me, all your porn files will still be there waiting for you.
Sorry, I have a weird sense of humor.
Lol, thanks buddy. Ive never had an android device with an internal sdcard so i was a little concerned. Thanks again.

I was wondering, is a data/factory wipe always necessary? When I flashed Revolver 3.9.3 for the 1ste time from stock rom, I did a data/factory wipe, cache wipe and dalvik cache wipe in CWM. When updating this Revolver rom to 3.9.5 using zip-file, I only wipe cache and dalvik cache. On my Moto I wipe cache and dalvik cache before and after the zip update when updating a custom rom, but I'm not sure if the latter is necessary. I guess a data/factory wipe is only necessary when flashing a new base rom?
wiping is usually recommended as sometimes if you install with out wiping it will cause weird problems :/

[Q] Full wipe with dalvik cache etc. on Stock Rom

Hi,
if the upgrade to ICS is available i want to do a full wipe with factory reset before.
How is the best way and in which order is best to do a full system cleansing with stock rom 2.3.6 installed.
First deletion of SD Card an than over the recovery menu resetting the rest?

I'm no expert but why would you delete the sdcard?
Root, install CWM recovery via rom manager. Select if you have 4g or not.
load rom onto root of the sdcard
Wipe data/factory reset
Wipe cache
Wipe dalvik cache
Flash rom
If you want to install a custom kernel instead of the one that comes with your rom of choice
After you flash the rom
Go back and rewipe dalvik
Then flash kernel
Reboot and enjoy

There's no point in wiping the dalvik twice, and instead of wiping the dalvik in CWM I'd use dalvik-wiper.zip by Morfic. Flashable zip, and it actually wipes the dalvik.
The rest is all good to the best of my knowledge.
Full wipe with GB stock rom before upgrade to ICS
Hi,
@polobunny
on the SD memory are two folders named .android_secure and Android where Android specific things are stored in. I have read that for a new and clean system build up would be good to delete this folders before.
@sookieball
I have only the normal stock rom 2.3.6 with stock recovery (no CWM) and want to stay there.
So then I think the best way is to go over the menu and do a reset to the factory settings. Delete the to folders on the SD memory manually and afterwards I will go into the recovery menu and delete the dalvik cache and then apply the ICS update.
Why i want to to this? I have at the moment a lot of useless Apps installed and i want to refresh all and start with a clean system with upgrading to ICS. Thats all.
Wherever you read that you should stop reading there.

ACTUAL steps for flashing a new ROM, CWM

I'm on CWM 5.8.1.3, and about to flash Team PTSD's AOKP build 39 and then flash their new Chimera ROM over it (looks awesome guys).
I'm worried about messing up my phone (yes, I've obviously been fine thus far) but I wanted a bit more clarification on the actual steps one needs to take in order to flash a ROM. I know there are instructions that say things like
Wipe datax3
Wipe systemx3
wipe dalvik/cachex3
But the actual corresponding items in CWM are things like: Wipe data/factory reset, wipe cache partition, mount /system /data /cache,
format /data /system /cache.
So I've been assuming that wipe datax3 = factory resetx3 and wipe cachex3 = format cachex3 and wipe systemx3 = format systemx3. I don't know if I needed to mount any of them either. With the presence of the brick bug I thought it might not hurt to have someone expressly state what options to choose when flashing a new ROM (in the language used in CWM).
edit: ****, I'm sorry I thought I was posting in Skyrocket Q/A. Apologies mods
All u gotta do is wipe data and cache and format the system

See, that's what I thought. The language is different though, and I wasn't sure if anything needed to be mounted before formatted.
So to reiterate. The steps, IN THE LANGUAGE ON CWM, are:
Wipe Data/Factory Reset x 3 (unsure of this)
Format Systemx3
Format Datax3
Format Cachex3
Wipe Dalvik Cachex3
Install ROM - Flash GAPPS
Reboot
Fix Permissions - Reboot
Yes that's it and its not a freaking language quit acting like its foreign to you its in English

Wiping dalvik & cache and all partitions except sd card.

Is it correct that you wipe all partitions except sd card and dalvik & cache before you install a new Rom.and after the Rom is installed do you wipe the dalvik & cache again one more time.If you do wouldn't wiping the dalvik & cache after your new Rom is installed erase,remove the new Rom that you just installed.Is it alright to just wipe the partitions except the sd card before installing a sense Rom over a sense Rom or vice-versa going from a sense to a nonsense Rom and or nonsense to a sense Rom. Thanks...

Hi,
If you want a clean install ,then it is correct to wipe all the partitions except the sd card.
A simpler way is to use a SuperWipe zip.
This does it all for you.
You only need to do it once,before installation of the ROM.
When I change Roms, Iwipe cash, then wipe dalvik cash, then I wipe data factory reset, then install zip from SD , reboot, and I'm finished. I don't format all partitions except sd. Maybe I should be doing that. I only wipe BEFORE installation and not after. It's been working for me I've never had a problem yet thank God! Usually I pay attention to what the developer says to do on the Rom site. Each Rom has specific flashing instructions. If the Developer asks to format partitioning of sd card I would do it because every Rom is different.
I just have not came across those instructions yet. I suppose everyone does things a little differently also. This is just the way I do it. Others might do it differently. I have not had any problems yet and I flash a lot! Just follow recommended instructions and you will be fine. Best wishes. Happy flashing !

Check your rom thread before using superwipe as it causes issues with some builds. An alrernative is to wipe user data/factory reset, then wipe both caches using 4ext recovery.

[Q] When and why Wipe Data/Factory Reset / Wipe Cache Partition / Wipe Dalvik Cache

Hi,
Today I successfully rooted my galaxy Tab 2 7 P3100. What I am not sure is when and why we need the
Wipe Data/Factory Reset
Wipe Cache Partition
Wipe Dalvik Cache
I want to understand because I plan to try couple of other ROMs. Should I follow the above procedure every time I flash a ROM or is there a better way where avoiding any of the above is an option.
Regards.
to minimize the conflict that would occur if you use a different rom base
try it without wiping, usually meet force close dialog after booting
all i know is that wiping cache will clear data related to applications, so if you have an app force closing all the time it is sometimes handy to wipe that app's cache from the settings or wiping the entire cache from recovery.
wiping data/factory reset however will remove any app you have installed and all your personal files that you've put on the device.
Basic breakdown,
If going from one base ROM to another base ROM like stock to CM, CM to AOKP, stock to AOKP or anything like that you will need to do ALL 3 wipes.
If going from like a CM10 nightly to a newer nightly you can usually just wipe CACHE and Dalvick
If you flash addons you will usually need to wipe cache and Dalvick
BASICALLY just do what the INSTRUCTIONS for the ROM your flashing SAYS to do.

First of all a BIG THANK YOU.
Now One more doubt there is this ROM which I want to flash and it says to wipe dalvik cache before and after flasing the ROM. Please confirm only Factory reset will clear the existing ROM and wiping Cache and Dalvik cache wont affect the existing ROM(or internal SD Data)
Thanks again.

OK well flashing any ROM will replace your current ROM, NONE of your files (music, pictures or things like that) are touched by ANY of these wipes, Factory reset wipes out installed apps, wiping cache and dalvik after flashing or hell wipe data/factory reset won't touch the apps "built-in" to the ROM.
remember the ROM is your operating system and your files (music, pictures, and other stuff) are in the internal SD which is a separate partition from the ROOT system folder where the OS files are.
Wipe Data/Factory Reset - wipes all APPS and Google account information and resets all devices settings to default
as for the other 2 read through the answer here http://android.stackexchange.com/questions/25859/why-do-i-need-to-wipe-dalvik-cache it explains what the other wipes are about.
Hope that covers it, basically jumping from one ROM to another the most you can lose is your basic settings and your APPS (which can be redownloaded, if you didn't use an app to back them up first, but you would lose any progress in your games if you don't back them up).
