I didn't want to bother the team by sending them through the "important question form" webpage.
Neither can I ask them on the development thread on XDA.
I am currently on the slimbean 4.2.2 build 3. Going to build4 the team recommend a full wipe, but then the update of build-5 did not specify such step. I wonder if that means from build-3 to build-5 an easy wipe (wipe cache and dalvik only and flash the latest build-5 rom) is sufficient to make a successful update.

To be honest this is never advised. Too many artifacts from the prior rom can cause issues. IT is always best to do a full wipe before flashing another rom. Be it update or not.

Most of the time it doesn't matter. An update that specifies a wipe should have a wipe during the process. A build after a build that specifies a wipe should have a wipe during the install if a wipe hasn't yet been applied.
So yes, OP you should wipe from 3-5 as 5 is built off of 4 which requires a wipe.

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.
Hey guys
I had started to use nightly builds. My question is should I have to wipe factory n Cache?
Sent from my Nexus S using XDA Premium App
Nope, if you continue to use the nightlies, just wipe dalvik cache,
If you come from different rom, just wipe data and cache and dalvik cache.
Once you are on the nightlies you never wipe anything. Don't listen to any nonsense about caches and dalviks just go to recovery, flash nightly, reboot!

Thank you.. do I have to wipe if I'm switching to different rom of same version?

You're losing no data wiping cache and dalvik, why not do it then, it saves you from trouble.

Because it doesn't "save you from trouble." But I'm not going to argue about it. The OP asked if he had to wipe when upgrading nightlies and the answer is No.

You are so wrong. Of course he needs to wipe Dalvik and Cache even if he installs another nightly. Its because the new nighlties bring new apps versions, or new kernel changes. Deleting Dalvik and cache forces the Android to reload the Dalvik cache for all the apps. Also, it saves you from trouble of incompatibility or FC's.

Different ROM same Android - wipe Data, Dalvik, Cache.
Same ROM same Android - wipe Dalvik, Cache.

Well you can have your superstitions but there is no rational reason to manually wipe your cache or your dalvik cache when upgrading CM nightlies, and that comes straight from the developers of the ROM who are more knowledgeable than I am. None of the CM devs have EVER suggested it, and when asked, have said that it is not something that should be done. I will take their word over yours.
EDIT: This is the closest I think we will find to a definitive answer: http://review.cyanogenmod.com/#change,4933
So, CM development team does not suggest a wipe of dalvik or cache when upgrading. The nightly installation instructions do not mention wiping dalvik or cache. I personally have flashed several hundred nightlies over the last year and have never wiped cache or dalvik when upgrading. Many many other users have flashed hundreds of nightlies each and have not wiped cache or dalvik and have not had problems. There is no reason to do this action, it is completely pointless. It is like saying "you must have your phone pointing to the east when you boot." Sure maybe it does not hurt anything but we don't really need to keep spreading this superstition.
EDIT: In re-reading this I feel like my posts come across as disrespectful and/or antagonistic. I simply disagree with what was said and I feel I have good reason to. But the OP can read about both points of view and then try for himself and choose what works best for him.
CWM recovery was developed from CM7 devs. So why do you think that they've integrated or made a option to wipe dalvik if that is not needed?
Especially if installing another kernel, wiping Dalvik is a must.
But you are right, the OP can choose himself either he will do that or not.
I don't think that your post is disrespectful and/or antagonistic, you have just expressed your opinion. If we don't discus issues with each other we are not gonna make any progress on learning.

There are lots of options in CWM recovery that are not needed when flashing
Like I said, in the link it is expressed very clearly that the developers of the ROM feel it is "completely pointless" (exact words) to wipe cache and dalvik when updating to newer CM build.
There are times when a user or developer might want to wipe cache or dalvik and so those options do exist. There are other partitions that a user or developer might want to format from time to time for various reasons as well. And the option to do those things is there in CWM recovery. But that does not mean they should be done every time, just because they are there.
In the link I posted, a submission was made to CM code to make it easier for users to wipe dalvik and cache and install a zip all in one command. The submission was rejected because the reviewers agreed that it was "completely pointless."
Why after so much time do you think "Wipe Dalvik Cache" is still obscurely placed in the "Advanced" menu of CWM Recovery? It would be very easy and simple to wipe cache and dalvik automatically when installing a ROM through CWM Recovery or at least put the option on the main page. Do you think that Koush just likes to give users a hard time? Do you think he wants it to be difficult for them to update their ROMs? I don't think so. I think he understand that it is an advanced function that can be useful in some circumstances but is not typically needed in 99% of cases.
The developers also note that the cache is invalidated via hashes automatically. So its basically auto wiped.
The only reason that I wipe is when the nightly contains a new kernel, dalvik should be wiped to eliminate possible problems.

I've searched for this question but can't find it. When I flash a rom do I wipe the cache before or after I install the rom?
Thank you

You are correct. But I didn't post enough information in my question. I am specifically asking about upgrading from an earlier version of the same rom. Jokersax cm9 thread says that when UPGRADING from an earlier version of cm9, I only flash cm9 and flash gapps. However, I have read multiple posts from xda and other websites where people recommend wiping during the upgrade process. I haven't found a single post stating whether to wipe before or after flashing. I want to make sure I correctly install the update and the confusion comes because cm7's thread says to flash then wipe, and jokersax cm9 says to wipe then flash. But like I said, it says nothing of wiping when upgrading to another version of cm9. Considering the number of posts that recommend wiping during an upgrade, I would just like to know if I wipe then flash or vice versa. Sorry for being a noob

I always wipe cache and dalvik just to be safe. If the rom I'm flashing specifically says to wipe data/factory reset or fastboot -w then I do that also. Or if going to ics from gingerbread or vice versa I always do a full wipe. If just updating the same rom I would just wipe cache and dalvik.

Ok but when UPDATING a ROM do you wipe before flashing or wipe after flashing?
My fear is that I wipe after flashing and it erases my update
I flash everything before and after and have never gotten into a bootloop after i started doing that, just don't wipe data after you flash some casue you'll discover there's no keyboard

Sorry I don't understand you. Are you saying you flash the upgrade, then wipe, then flash again? And never wipe data after flashing, but it's ok to wipe cache after flashing ?
Hello guys,
Good to be part of the Android family here.
I just got a question to ask in behalf of all Noobs here.
Can anyone enlightened us on the proper way and procedure to flash another ROM if we have already done so,
like, if my ROM has an update, what should I do? In the proper way... Wipe? Dalvik Cache?
Currently I'm running Jamal's GE Jelly Bean AOSP ROM on my S4. I have had a soft-brick experience with mine and I don't wanna screw it up again. Going through Odin and Re-Root is really a chore, and bad for my phone(? perhaps?)
Thanks guys.
Cheers.

If u wanna update the same Rom u have mostly wipe cache and wipe dalvik cache and install the Rom and rebooot
Again it depends check the installation procedure given on the Rom "OP" only he will know best whether the Rom is full wipe or no wipe
And if u wanna install a new Rom
From recovery wipe data/factory reset wipe cache / wipe dalvik cache... Then install Rom and reboot all done
Edit always have a nandroid backup in pc or sd card to be on the safer side
.
Got it thanks a mill!
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)

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.
