is it safe to install CWM and flash a rom if im usign ART runtime rather than Dalvik? or should i revert back to dalvik first?
As when flashing roms i know it wipes dalvik cache etc..
no it wont matter, it is perfectly safe, the flashing of the rom will maybe even switch the runtime back to dalvik.

Do you need to Wipe Data/Factory reset from CWM when flashing from a custom rom to another?
or can I just wipe cache partition, Dalvik cache & battery stats.
If I do Wipe Data/Factory reset from CWM, does it erase your internal SD card?
that's just the same question i want to ask!

Sorry if this is a noob question, but currently my phone is running on the alliance rom for t-mobile (here: http://forum.xda-developers.com/showthread.php?t=2748569). When updating to the current version, is it necessary or advisable to do the whole factory reset, wipe dalvik and cache shenanigans, or can I just install the rom by flashing it over the current install?

Hi
I'm currently on 4.2.2 and decided to upgrade to a 4.4 rom namely SlimKat.
Just wondering whether I need to flash new version of radio and bootloader before the ROM?
I believe that I need to do a full wipe of my phone.
Does full wipe means the following?
Wipe Data/factory reset
Wipe Cache
Wipe Dalvik-Cache
Wipe Battery Stats
Do i need to format system and boot?
Thanks in advance
Yes, do a Data + System + Dalvik + Cache wipe and then flash the Slimkat.
No need to wipe anything else or flash new version of radio and bootloader.
Hi,
I've recently done a succesful flash of Blisspop after a full wipe.
Now I want to update, but I don't want to do a full wipe. Simply installing the zip on-top gives a permanent booting screen. Can you update without starting from scratch?
Did you wipe cache & dalvik after flashing updated zip?
I did not. Is that the only required extra step? And will I lose data if I do so?

No, you only lose data when you wipe the data partition
In recovery, you'll see different named partitions, cache, dalvik cache, system, data, etc etc
If you wipe System, you wipe the ROM
If you wipe Data, you wipe your user data
Caches are just temp partitions, safe to wipe any time, only side effect is a longer first boot as Android needs to re-cache everything
But yes, you do need to wipe the caches when updating to a newer version of the same ROM/Droid version, and no you won't lose your data
Here's how I do it:
Wipe System
Wipe Caches
Flash new ROM
Flash new Gapps
Flash SuperSU if needed
Wipe Caches again
Reboot
Result = New ROM with no loss of data
That's a clean flash, a dirty flash is how you did it without wiping System
If you are moving to a newer version of android, or a different ROM, wiping data becomes more necessary, especially if the move is to an older version of droid
Thanks. I'll try it out.
Wipe Data, Cache, Dalvik Cache and format /System
is necessary ""after""
or before ???
or both times when WE port the new rom ? ?
or why we do it if we not do it what happened?
When you decide to install a new ROM, then you have to do those wipes,
Cache and Dalvik Cache are related to every APK in the ROM, when you start boot the ROM for the first time, Dalvik cache indexes all APKs and cache it's dex files into the Cache partition, that happens only once, and you can actually see this when Android tells you it's "Optimizing Apps x of x",
So, what happens if installed a new ROM without wiping Cache and Dalvik Cache?,
Dalvik cache won't index the new APKs from the new ROM, and you'll end up having a ROM full of FC msgs,
So, that's why you need to wipe Cache and Dalvik Cache when you install a new ROM, before the ROM or after that won't matter, but don't boot up a new ROM without wiping those partitions.
