I know to do a system wipe/factory reboot, but do I also wipe the dalvik cache every time?

It's the safest way to do it, yes. If I were you, before doing anything, I'd install Titanium Backup and create a backup of all of you installed applications. Then, I would create a Nandroid backup for this current rom.
Each time you install a new rom, install Titanium Backup and restore your applications. Then, finish it up by creating a Nandroid backup. In the end, you can just flash between Nandroid backups to switch back and forth between roms that will contain all of your applications and user data.

Alright, cool. I do make nandroid backups for everything and I use Titanium. I just wasn't sure on wiping Dalvik everytime. Thanks!

I know you should make a backup. So when you wipe and flash a new rom and kernel, do you restore data and that will restore all the programs you had prior at the time of the backup?
Thanks.

If you do an advanced restore of your data through CWM recovery, yes it will restore all your programs and settings. However, this can cause problems as the old data does not get along with some ROMs.

So it is best to just reinstall programs?
I would use Titanium Backup or My Backup Pro to back up you apps+data. After the flash you can either restore everything from the backup or just the data. Some people have said that it's best to re-download your apps from the market and only install the data from the backup (as opposed to restoring app and data). I don't know, I've done it both ways and have never noticed a difference.
I have typhoon 3.7.0 clk installed in my HTC HD2. I would like to update it to version 3.8.2.
Clould somebody tell me a procedure how to do it ?
Will I lost all my installed apps in my HTC after update or update has no effect on apps I have installed in my phone.

You won't lose anything. Just make a CWM backup (as a failsafe, you shouldn't need it) then flash the new version over the old version. Don't do a wipe or anything like that, just flash it. After the update is completed, clear the cache partition (from the CWM menu) and the dalvik cache (in advanced in CWM) and reboot. First reboot may take some time but after that it should be as it was before, just with all of the updates to the ROM.
Just install new ROM
I have some situation like you have, Typhoon 3.7.0 update to 3.8.0! What I did is just pull the ROM to SD card, and then enter recovery choose " install a zip from sdcard" choose your files, and install and it just all set! Your personal data will not be delete!
i just installed this ROM from MIUI, didnt do task29, installed and wipe cache and dalvik.

I don't quite understand your problem with Cyanogen settings, but to backup and restore just use the CWM backup. It will backup literally everything on your phone and any apps you have on your SD card. If you ONLY want to backup your app data and other data which you want to restore onto a different ROM, you can either:
1. Create a CWM backup and when restoring, go to advanced restore and restore data partition
2. Use Titanium Backup to backup apps, Super backup (I think that's what it's called at least) to backup contacts, SMS and call logs and (probably unnecessary but you might need it) APN backup & restore to backup your APN settings.

Thank you! I will try that
I'm having a little trouble understanding nandroid vs. other forms of backup and would appreciate some clarification. I'm running CM nightly on my Fido (Canada) G4. I took a nandroid as well as titanium backup of the factory stock image before I flashed CM.
A poster in the last thread I made suggested if I wanted to restore to stock, I could simply restore the nandroid, but I've also seen people say you shouldn't use nandroid to go across ROMs. My understanding is that nandroid is like having a filesystem backup, which would obviously not react well if you restored it over a new operating system (e.g. two different versions of windows). Or is nandroid more like say Acronis, which takes an entire disk image and overwrites everything?
Other misc questions:
- If I do restore via nandroid, do I need to wipe all data / cache / system data before or after the restore?
- I assume I can use titanium to restore SMS + all non-system apps across ROMs, which would save a lot of time.
- If I'm going from one CM nightly to another, would titanium work for system apps (e.g. all my settings, or contacts, etc)
- If I want to flash a new CM nightly, do I need to follow the entire wipe procedure just as if it were going from one ROM to a completely different one?
Thanks!
always make a nandroid in recovery. i recommend keeping it on your micro sd card. in the event you need to return your device to it's previously functioning state, restore the nandroid in recovery. if you are running an aosp rom and your nandroid is touchwiz, wipe data, cache & dalvik before restoring the nandroid. if the backup is on your micro sd then feel free to wipe system as well.
if you want to flash a nightly or update to a rom you are currently running, simply wipe cache and dalvik then flash the update, gapps and any custom kernel that you may be running.
i cannot answer your titanium backup questions because i do not use that program

yes, that's about what I have. ok, thank you for the clarification of what to wipe! that's good to know.
re flashing a nightly/update: using your method should preserve system data yes? so no need to reinstall all apps or system data?
and thanks, I'll hold out hope that someone with titanium expertise will be able to answer that one

yes, system/user data will remain. understand, however, that if you perform one of these dirty flashes and you have a problem with the functionality of the ROM, you'll need to do a full wipe and flash to see if this clears the issue before you report the problem in the development thread.

Your right on both titanium questions.. However its not recommended to restore system apps you backed up on a aokp/aosp ROM to a touchwiz ROM and the other way around... Other than that like I said your fine
Sent from my WANAM'ED AT&T S4
So I am currently on Paranoid Android and wish to switch to another ROM (most likely AOKP or PACman just to try). In TWRP recovery, what would I select to just back up my app data and NOT my ROM, and after that is possible, what must I restore to get it back and in what order of flashing alon with my new ROM and GAPPS???:silly:
You can go into TWRP and backup and choose what partitions you want to backup. However, I'd suggest you backup everything and don't try to restore the data to another ROM.
I use Titanium to backup all app data as well as MMS history, WiFi networks etc then do a full backup in TWRP. Then wipe everything and flash the new ROM. Then boot up and reconfigure accounts and restore apps + data with titanium.
It may be a little more effort but this way you can always roll back to the previous setup if anything goes wrong and you're less likely to run into any weird issues from moving data around between ROMs.
Or you could try something like app2zip off the play store to make a flashable zip of only selected apps and data which is probably safer than the whole partition. If you do a full backup first you can always rollback if something goes wrong.
When using Titanium Backup, when I hit run backup, where does it go and how do I restore it after I flash my new ROM. Or do I do the update.zip option and flash that when I'm doing my new ROM?

It goes into a folder on /sdcard called TitaniumBackup. When you flash a new rom, you will need to redownload titanium backup. When you redownload it, it will find the backups and you can click on the app to restore it.
Theres no need to use the update.zip method. Do it like this ^
I have been doing some nandroid backups with online nandroid backup app and noticed the settings app was missing shortly after restoring desktop data from a nandroid backup using nandroid manager. Please help! This is a major inconvenience!

Thanks for the response. What do you recommend I do in terms of backup? Would nandroid backup and later restore with nandroid manager app of user apps/app data work? How about my rom's settings I've worked so hard setting up?

Make a nandroid in recovery. I always use titanium backup to restore apps. If the data for settings.apk is in your data partition it won't be touched. The other APS shouldn't be touched either. The backup will just be for good measure.
