I'm running the 9/27 CM nightly but I don't want to have to wipe data and cache if I don't have to. I want to upgrade my current nightly Rom but I don't want to have to set up the phone again. Do I have to wipe to upgrade my nightly? Or is it safe to flash the new one over mine. I don't think it would really make a difference cause they are both cyanogenmod. Thanks!

I would recommend a full wipe before installing the Rom. Otherwise some things might not work properly. I installed the Skyraider vanilla Rom without doing a full wipe, and there were a bunch of things that didn't work properly. I did a full wipe and reinstalled the same rom, and everything works perfectly.

I'm currently running cm7 rc3. Do I need to wipe cache and data if I'm upgrading to cm7 rc4?

I did a flash over, didn't wipe anything. No problems as of yet.

Its usually a good idea to at least wipe cache and dalvik. Shouldn't have to worry about data unless you are having problems.

Wipe cache and advanced>dalvik. Then apply the CM.zip, then GApps,zip if you use those, and then any custom kernel that you use.
Doing a backup beforehand is always recommended

Same thing here, no problems yet.
Rule of thumb is to just wipe the cache/dalvik if your updating to the same ROM, just a new update. It's really only when your cross-flashing a different ROM where you need to do a wipe data/factory reset.
I flashed the kernel and Rom virus gingersense and was thinking about flashing a different Rom but was wondering if i make a backup before i flash do i still have to do all the steps i had to do to flash this Rom or will it automatically be done?

You need to backup that rom in recovery [in case you want to go back to it.]
To flash new rom:
-after backing up the current rom, wipe factory/data, cache, and dalvik cache
-flash rom in recovery
-if its a gingerbread rom, wipe cache and dalvik again, then flash the latest gapps.
-if you flash a custom kernel with it, wipe cache and dalvik cache again, then flash kernel
-reboot
Thanks i was asking cause i wanted to try out the miui roms and if i don't like them i would like to go right back to genger sense wit the kernel without going thru all those steps again

No problem. Just follow my steps and it'll bring you back to the gingersense. [after flashing miui, and if you want to switch back, just restore the backup of gingersense]
I would recommend naming them with a file explorer/mounted to a pc, because if you have multiple ones, you'll forget. Just don't use spaces in the names of the actual backup, and do not name the folder the backups are in.
I recently flashed cm7, works great. The only thing I'm having trouble is with the apps. I can't download the apps I had previously from the market because It says I have them installed already.
So how do I fix this/restore my apps?
thanks
Try and clear data for the market app and see if that works for you.
Erm, how exactly?
If you go into settings and then applications. Find market under all and click clear data.
Part of my problem is that I don't have the market app installed
Did you flash a Gapps package when you flashed your ROM? That will give you Market and other basic Google apps. I believe CM is packaged without an integrated Gapps loadout for legal reasons.
Sent from my Incredible 2 using XDA App
No I didn't flash Gapps, I just installed market via apk, cleared the data but I can't use the market cause I cannot set up a profile that its asking for.
How would I go about this Gapps package?
There was no data to clear anyways.
About to try this
wipe data+cache
flash cm7
wipe data+cache
flash gapps
If you wiped system, cache, and dalvik cache before you installed CM7, you shouldn't even need to wipe. You'll just reboot into recovery and flash the Gapps .zip just like you flashed your ROM.
As far as finding it, I'd just Google "cm7 Google apps" or "cm7 gapps", you'll find a download link for the .zip. Keep in mind that, unlike the ROM itself, the Gapps package isn't specific to one model phone.

Thanks I'll try flashing gapps
It worked great, now im getting a server error in the market.
Also getting a network error trying to use weather
It broke my internet, completely. 3g and wifi

Which cm7 version are you using?
Sent from my ADR6350 using xda premium
In that case you might want to start from scratch:
Boot into recovery -- nandroid backup -- factory reset -- wipe dalvik cache -- install cm7 -- flash gapps.
And yeah, check to make sure you're using a current stable cm7 build.

What version of CM7 did you flash?
depending on the version of cm7, i would flash one of aero's kernals
http://rootzwiki.com/topic/7717-kernel-aeroevan-vivow-kernels-for-aosp/
v8 needs to be for 7.2 otherwise, flash .7 version.
7.2 + Aero kernel .8 is an amazing combination. Do that!

7.1.0.1 stable is the version im using.

I flashed Sandvold's ICS 0.8.1 yesterday, but after reading a few threads today I saw that it's better to do the custom install instead of the typical one. I did a nandroid and decided to simply flash the rom again without clearing anything.
It seems fine so far, but I'm wondering if this can lead to any problems?
Also, do I need to reinstall a2sd after re-flashing?
I think that if you downgrade from ics to gb than you need to make a full wipe but if you upgrade than I think it's ok

If you are with the exact same rom then a wipe shouldn't be needed and a2sd should stay if you don't wipe.
Try it and if it doesn't work do a full wipe I've never seen anyone say you'll break your phone if you don't wipe. Someone on Sandvold's thread recommended app extractor from play store as an easy way to restore after a full wipe. Didn't work for me but I only tried it once so you could check that out. It just restores everything from your nandroid

If u are flashing the same rom (newer version) u still have to wipe dalvik. Its better anyway just to do a backup then full wipe and flash the rom then restore
Sent from my HTC Desire
Always wipe Dalvik, sometimes, the rom setup menu does it automaticly.
OK, I know that you are supposed to wipe every time you flash a new rom. I am on CM9 Stable. I want to update to CM9.1. I think i need to wipe. But considering CM9.1 is an "update" I might not. So If I don't, then it'll save me so much time. But if I need to then OK. I don't want to have to wipe even though I didn't have to. So do I have to wipe when flashing to CM9.1 even though I'm on CM9?

No need to wipe, coming from Cm9 you're good to flash away. You will want to wipe cache/dalvik though afterwards if you get a boot loop.

I used twrp, factory reset, wipe system, wipe dalvik, wipe cache, flash 9.1, flash gapps. Prosper.
