For example: there's a new build out for the current rom (cm7/9/10, Miui etc...) I'm using, and it contains various fixes or whatever. Can I simply flash the updated rom, without wiping cache and data, and be fine?

No data wipe is just fine. Wiping cache/dalvic prevents glitches from occurring. I just built them into my Kangs to make it easier to upgrade, but its recommended that you do the wipes inbetween same roms when upgrading. Not a bad idea when changing themes either.

when updating a firmware?I usually wipe all the 4 options and end up losing all my apps and SMS and stuff.
So, are all 4 wipe options to be performed?and is it normal that i have to reinstall apps each time CM is updated?
If i am not mistaken you do not have to wipe from CM rom to CM rom as of 4.1.99.

Correct, as long as that's what Cyanogen states in his directions. Occasionally devs will release a ROM that makes very significant changes that do require a wipe.
That being said... OP, all you need to wipe is the system itself. You'd only need to wipe an ext partition prior to flashing a new ROM if you had Apps2SD AND the dev recommends a wipe of system.
My basic question is can I repeatedly reflash the same ROM to my Epic without wiping data between flashes?
I flashed a ROM and then manually flashed a number of add-ons and optional installs from other ROMs. My phone is now in a state that I don't like. I thought I did a nandroid backup after the initial ROM flash, but I didn't. I'd like to just reflash the same ROM that I already have on my phone, hopefully just wiping cache + dalvik first. I'd rather not wipe data and go through all that again if I don't have to. Is this safe to do?
Yes its safe. Only reason they say to wipe is going from one rom to other rom u may get some probs.

Disclaimer: I'm used to my old Evo 4G and use a triple wipe script built into my recovery (smelkus) whenever I flash a rom. It pretty much wipes everything.
For the Nexus 7, what needs to be wiped to flash a rom? I did a factory reset, wiped data, wiped cache, wiped system, wiped dalvik-cache, and then flashed a new rom, but I wasn't sure if all that was necessary. I'm using the latest TWRP recovery.
If I'm moving from one rom based on a jelly bean version to another based on the same version, am I ok?
Can I assume upgrading to a new version of the same rom that I don't have to wipe? (I know this one is rom specific, but in general.)
Can I leave data and will that retain my apps? Otherwise, I use Titanium Backup religiously on my Evo and now on my Nexus 7.
I searched within some of the rom instructions as well as the rooting guides, but didn't see anything specific as to what to wipe. Some threads seem to say just factory reset and maybe dalvik-cache.
Instructions with what to wipe usually come in the original post of each ROM. Usually the same ROM with different version only requires a cache wipe while moving between different ROM's requires a full wipe/reset + dalvik.
Worse comes to worse you try something and it doesn't boot and you get back into recovery and fix it.
This is my first android phone and therefore cm10.1 is the first ROM I've ever had so I've never updated my ROM before. Goo manager sent me a notification saying that Cm10.1 rc2 is now available but in order to download it do I have to wipe my phone to factory default or can I just install it over my old cm10.1 and keep my apps and stuff?? Thanks

The whole point of the CM updater is that you don't have to wipe anything - not data, not cache. Just start the download, click OK to install when it finishes downloading, and it'll flash itself over your previous installation. The same applies to downgrading to an earlier release - no wipe needed.
Yes, you can keep your apps and system settings. No need to backup and restore - they'll be exactly the way they were before you downloaded the update.
However, if you are migrating to an entirely different ROM (i.e. not the official CM), then yes, you probably need to wipe. Going back and forth between different updates of the same ROM doesn't need wiping though.
You can just flash it normally using CWM. It's called Dirty Flashing. DO clear Cache and Dalvik before flashing

So what do I do just download the ROM and its gapps again and flash them both? Which one first?

Wipe Cache and Dalvik -> Flash ROM -> Flash GApps -> Reboot.
And don't forget custom kernels

No need to flash Gapps again on CM, unless data is wiped because of the b/u scripts.
The updater script in the ROM also wipes the Dalvik for you.

Actually you don't have to do any of that except flash the rom and reboot. All the rest is automatic.
I reverted to my backup that I made before flashing. Franco kernel didn't work and I had all the crappy apps I uninstalled from cm10.1 like Apollo and stuff .. What's new is rc2 anyways?
updating cm10.1
Hi all
I am currently using cmw6.0.2.3 and rom cm10.1.20130411-EXPERIMENTAL-p3100-M3 and would like to switch to using cm10.1 nightly. Reason to switch is because pie control in M3 is not working and I saw in some video that it is working in nightly. May i know how to update usingmanual mode please? And also will it deketenall my installed apps and data?
Thanking you all in advance
People,
1) Nandroid Backup.
2) Dirty Flash, if something doesn't work or it starts to fails, restore nandroid, backup everything (needed) with Titanium backup or similar, wipe everything, flash, restore, win.
I am sure this is a stupid question, but I've looked and not found a definitive answer so I'll try here.
I have a LG G2 (AT&T) which I have rooted/clockwork/CM11. I did most of it when I had a failed OTA send me into a bootloop. (I had rooted the stock and removed some bloat which it didn't care for). I love CM11 however, there are some issues with the M5 build that I think are solved in the nightlies.
My questions are as follows:
(1) If I start flashing nightlies am I going to loose everything on my phone?
(1a) If so? How do people handle nightly flashes and always having a phone that needs setup?
(1b) If not, how do I flash the CM rom? I assume through recovery like I did before.
(2) Is there an easier way to backup and restore my setup to my phone?
(2a) I have titanium backup, and I have backed up all system and apps. However, I am not sure if restoring that will mess things up after flashing.
So basically, I'm looking to find out how people use the nightly builds and still have a mostly functioning phone on a day to day basis?
Thank you!
Before flashing a nightly for the first time:
You will need to wipe cache, dalvik cache, and data (user data--not internal storage).
Updating to the newest nightly:
You will only need to wipe cache and dalvik before flashing the new nightly. You will not lose your setup or apps. CM has its own OTA app that will automatically install new nightlies via your custom recovery (CWM or TWRP)

Thanks! I'm new to CM, and the thought of wiping my phone every evening was kind of scary.

Yeah once you're on nightlies, it's not a big deal. But after your FIRST flash of the nightlie, also be sure to flash the correct GApps package, which includes apps like the Google Play Store.
