I've been thinking. I wonder if it's best to wipe everything (system, cache, dalvik, factory reset) before you do a nandroid restore. I thought I remember reading in a thread once that someone thought some things carry over from the rom you were on even though you restored your previous backup. Does anyone wipe before they restore a backup? I usually don't but this last time I did. I don't think I'm going the notice any difference tho but maybe that's why some people have problems. If they're on a rom that has a bunch of bugs some of them could carry over without doing a wipe before restoring a backup.
If you look at the nandroid procedure it wipes system and data. I never thought of the caches. Hmmm.

So I'm running PnP and wanna run cyanogenmod 6 that got ported. If i make a backup and decide i don't like cyanogen (which i doubt) then i can just do a restore and everything will be there? In the thread about cyanogen it says wipe data.. so i just wanna make sure that i can get everthing back if i dont like it. And is there a way to just wipe data other than wipe data/ factory reset?
Yes, everything will still be there when you restore a backup. Just make sure to reflash whatever kernel you had been using on PnP if you restore your backup.
No, wipe data and factory reset from recovery are one in the same and can't be done separately.
So reflash the kernel before I do the restore?

When a restoring a Nand backup through CWM, does it actually wipe data,cache,boot etc..
Or do we have to manually wipe everything.
I noticed that when restoring it said erasing boot and stuff.
Asking because i always run into trouble when restoring a backup, Would be helpfull if someone can share the proper way of restoring a backup.

By default restoring a backup through cwm recovery does not wipe everything. If you choose to restore through Rom Managaer you will be given the option to wipe data, cache etc. I would recommended doing wipes manually, just to avoid any issues that may occur from not doing it before a nand restore

Wiping data/cache is enough or should we format boot/system etc?
It'd be better to do a manual wipe before restoring (system, data, cache, dalvik).
I want to update my Rom from NSCallob 1.0.51 to 1.0.60 without losing my apps or at least using some kind of backup to restore my apps after the update. Any help would be great thanks.

Titanium backup for sure.
I don't know that ROM specifically, but if it is just a minor release update you may not have to wipe anything but dalvik cache. Personally, i'd do a nandroid backup, wipe dalvik cache and cache, then flash the new version. If there is trouble, restore the nandroid, use titanium backup and do a full wipe, then restore with TB.

Just wiping dalvik cache will surfice when updating NSCollab! I know because I've done it myself with this rom on quite a few occasions!
Yup just wiping the dalvik cache will it freeze at the Google bootup screen, luckily I didn't a backup prior to the update!

Here are some tips on what not to do when restoring a nandroid
A. Forgetting to wipe system before restoring a nandroid
B. Forgetting to wipe data, cache, and dalvik at the same time

Yeah wrong section.
My advice: know which kernel you are on before doing a nandroid backup. Make sure you are on a compatible kernel first, flash the same rom as the nandroid backup just in case.
You know better
Forgetting to run Qkster wipe script.
Sometime renaming the nandroid zip creates trouble.
Actually I was referring to when you wipe everything on ics cwm recovery and trying to restore a nandroid

I've restored nandroids many times and have NEVER wiped anything before doing so without any issues. I'm not sure why you'd worry about wiping everything when it is all overwritten by the restore process.
it happens between the Slim ICS Restore and CM9 flash
quck and easy one, when doing a nandroid restore do i need to wipe all partitions or just go ahead and do it?
Yes I Always wipe before restore . Also wipe cash and dalvik, I also factory reset and stay in recovery upon completion to restore . Then reboot. This gives a clean installation. You're making sure the old Rom is gone before restoring. Hope this helps. If I'm in doubt I always wipe. Just to be safe. Remember even though is a backup, your still coming from a different Rom. So you will want a clean installation before restoring. I do my restorations this way and had never had a problem.

No. It does that on it's own.
What you are supposed to do though, is search before posting a new thread.
well i have 2 contradicating answer here...

Hi,
No need to wipe before restore.
The whole point of a nandroid is to wipe what's currently there and restore the backup you made. Wiping before restoring is wasted time/power/flash writing.
