Basically, it's the area where all the system files are stored;See here: http://www.addictivetips.com/mobile...plained-boot-system-recovery-data-cache-misc/. There's nothing to "achieve". All you should need to do is do a full wipe from recovery and flash the rom (make sure you create a nandroid backup first and clear dalvik cache after).

Yeah you can just restore from your backup, but before ruestoring it, do the following steps:
1. In recovery, wipe your Data
2. Wipe Cache
3. Wipe Dalvik Cache
4. Still in recovery, under mount and storage, select "Format /system"
5. Then you can restore your backup.
6. Fix permissions
7. Reboot to system
And you are done.

If you want Nick's MIUI 360, you don't need to install stock MIUI, just do the steps above, but instead of restoring your backup, just flash MIUI 360...do NOT flash MIUI 360 over stock MIUI (in this case, over your backup), if you do, most likely you will get tons of FCs. If you want MIUI 360, its recommended to do a clean install, not flashing over anything.

[Rom] How to update and not lose any data?

First of all sorry for my bad language
I've a Lg 2x (Aka Optimus Dual) temasek's UNOFFICIAL BUILD, now i saw an update from temasek. I'm asking how i can install the new room file as a simple update without losing any app/contact etc.
Well if it's possible what's the correct way to do an update of a custom Rom ?
Very thanks,
Sorry for the question but i've googled and nothing, also searched here but nothing
if its a update of the same build jus erase cache and dalvik cache and install the rom. then ur data remains untouched. but if the rom is different u need to full wipe. data will be lost. but u can sync contacts to gmail and retrieve back any time.

What does errase cache and dalvik cache do? Does the settings stay the same or do you have to set them again when you update? If it delets settings...can you update without errasing cache?
Nope...clearing cache and dalvik cache only wipes unimportant info...your settings will be there as long as you don't press factory reset...

exactly. but look for the requirements for the update. sometimes even updates may require data wipe if the dev states it.

All the above is good and true. I'd like to add that I always make a ROM backup with ROM Manager before I update my ROM. That way, if something should go wrong, I can get back to where I was before the update.

Dude you could just install Titanium Backup from the play store and back up all the apps and data you want to. And yeah, your device needs to be rooted. Cheers.

[Q] Installing our selected ROMs data/cache

When we reboot into cwm recovery to install our selected roms, do i need to wipe the data and cache AFTER or BEFORE i install the roms / gapps that i want to? Need help here !
- One more, those who are experience like me when i installed (cm10 port by Psyke) noticed that music app does scan SD card, but then no songs are shown when the app launches, thus leaving it to be blank / left only symbols at on top of the screen . Is really music doesnt work yet for the beta release? thanks for any response

If it's the next version of the current Rom you have, then wiping /data and /cache partitions is not nessesary. If it is an entirely different Rom then you should do a wipe as the phone won't boot properly.
As for your second query, a temporary solution is to use a different media played. I had the same problem with the initial cm10 builds for the galaxy s3.

Data cache partition
Erm ok. But wiping cache partition doesnt really wiping my items in SD card right ? and u said if other roms need to wipe the datas and caches but i need to do it BEFORE or AFTER i install the rom? i mean before we install i need to press the wipe data n cache OR after i install wipe data n cache?

Wiping /data and /cache doesn't wipe your sdcard content. It only wipes your installed apps and its data.
Doing a wipe before and after doesn't matter. But generally we do it after flashing a ROM.

I think if u wipe data/dalvik, restore, reboot, propably will work

You can restore the backup with out data wiping since cwm recovery wipes /data and /cache before restoring a backup.

Mod size is big you need to check system partition free size.. Comparable Rom etc

there only two possible reasons
1. you are using wrong kernel which is not compatible with your rom
2. your system partition size is small to accommodate the rom
flash stock ftf exclude simlock and other options

[HELP]{Q} Preload Partition on AOKP Roms

Hi
Should AOKP or CM roms have the preload partition. I am using rootbox and i have a preload partition on 500mb which is not being used. The folders are empty also i cannot delete them. I think it is wasting space or am i wrong. i seem to be running out of space now and then. Should the partition be there. If so why is it empty and not being used and occupying 500mb..If it is not needed how can i delete it.
Thanks
Also using rootbox, I have the preload folder but there's nothing in it. Did you come onto rootbox from the stock (or stock based) ROM? If you did, I'm assuming you didn't wipe the preload folder?
There may be a better way to do this, if anyone has one please shout out. Otherwise:
Flash a stock ROM (using mobile Odin pro you can root it on the fly).
Flash philz kernel. From philz recovery, wipe data, dalvik cache, cache, and format /preload and /system. Immediately after doing that, flash rootbox again.

what is the size of your preload folder/partition .. i use partition manager and it tell me its 500mb .. and its not getting used..if i uses philz kernel wont it create the preload partition again ??
Mine says 0bytes. Yes philz/stock will create the preload folder again, but will allow you to wipe it before the flash. I don't know how to wipe it from rootbox.

see post above .. thx
Mine looks the same in the same app, no need for me to post mine. I just interpreted it that it was saying that I wasn't using the space, as it's only 8 MB. I didn't see it as a problem
