[Q] Rom updating w/o losing data?

Updating aokp for example, the aokp updater told me about the update but is it the same process as installing for the first time? Will I lose my apps and everything or does it only wipe cache? What step in roms delete everything, format data or factory reset or both?
Cheers.

No wipe needed if updating.I recommend wiping cache and dalvik-cache for good measure tho. And you have to reinstall gapps after the rom as well.
When a wipe is needed you want to select factory reset. Never select wipe/format data as it'll wipe the internal storage too.

Then what about...
If you are already on AOKP and doing an update:
1. Make a nandroid (backup in CWM)
2. Format /system
3. Wipe cache
4. Wipe dalvik
5. Install new ROM zip
6. Install gapps
If you end up with issue or coming from another ROM, do this:
1. Wipe data/factory reset
2. Format /system
3. Wipe cache
4. Wipe dalvik
5. Install new ROM zip
6. Install gapps

Isn't a Format/system wiping the apps? Or does that not affect the apps? By format on my recovery it says formatting the sd card deletes everything (on TWRP).

edit:
if I wipe my dalvik cache and then I would like to restore my previous rom (backed up 1week ago)... would be everything okay? without bugs?

Try this method.
1. Boot into recovery
2. Wipe data
3. Wipe cache
4. Install zip from sd-card and wait till it flashes
5. Wipe data again
6. Wipe cache again
7. Install gapps from sd-card
8. Wipe cache after flash
9. Wipe dalvik cache now
10. Hit reboot and enjoy

[Q] Going from CM Stable to Nightly?

Do I need to a full flash or a dirty flash?
Dirty flash as in wipe cache and install rom.
I'm running Cyanogenmod 10.0.0-Hercules and I want to upgrade to this nightly: http://get.cm/get/6id
I was told not to use CM's built in updates system.

Thanks for your reply, that answers my question. One other thing, do you have a link for the new Google apps?

Mount and Storage - Format System, Data and Cache

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
