Hey guys (or girls) I just had a quick concern about nandroid backups and restores... When I do a backup of the current state of my phone, and I'm running flawlessly on a rom. If I happen to try a different rom and don't like it so I choose to restore to that certain backup. Will there be any problems like force closes or apps acting up all weird? Sorry guys just never actually have done a restore of a nandroid.
I've never had any problems. I always wipe says, cache, and delvik cache before restoring a back up though.

just to be safe i always also do titanium backup for all my apps on a separate sd card whenever i test a new rom out as well as a nandroid. sorry if this is a newb tip. i r newb also.

yea i literally backed up everything via titanium backup just in case and anything dealing with flashing and or using adb i do a nanodroid just in case
I always forget to wipe dalvik and cache but I've never had any problems. The first time I installed Blazer ROM 3.5 though it would always force close when I flashed the ICS theme but not the regular. Somehow it was fixed when I DIDN'T wipe cache/dalvik even though the instructions said to. But I'm noob too so I have no idea

I was under the impression a nandroid backup was like a full clone that you'd do on a computer. But after restoring with a nand backup there's always a ton of little settings I need to change

+1...are you performing the backup from the recovery screen or using the adb commands? What recovery are you using, CWM or RA? I know CWM was missing things when performing a wipe so maybe the same holds true for performing a NAND backup? I am using RA and I have not run into this problem.
Off the top of my head.. I always have to reset my Handcent message ringtones and Exchange account information.
Maybe I was a bit frustrated when I typed 'SO MUCH'. But it definitely misses some stuff.
I use Clockwork

Again, are you sure CWM was missing things during wipe, or are you just repeating what you've heard? I assume you're talking about dalvik-cache, and my testing shows that this is NOT true.
Oh, and I always lose my custom dictionary too.
and your backup is up-to-date?

It backs up absolutely everything. You must have used an old backup.

Well from my experiments cwm doesn't wipe dalvik. When I did a wipe and flashed fresh 0.5.3 I was stuck in loop

Yep. It's the very last thing I do before flashing a new rom
while were on topic...
so proper nandroid backing up is..
wipe data/factory reset
wipe cache
wipe dalvik
THEN do nandoid backup?
or is it.. do nandroid backup first THEN do all the butt wiping?
no no no, backup first then wipe. Otherwise you are backing up a blank phone pretty much
...For OP, not sure but is it possible the application data like handcent is not stored on the phone but in the cloud? Or maybe on the sd card and it does not link the old settings file? Are you using app2sd?

Nope. Haven't tried app2sd yet
Well, then the only thing else I can offer is using titanium backup or the like. What rom are you using when you did the backup?

Did you check to see if the dalvik cache was still there after the wipe? Because it resides within the data folder, so doing a data wipe automatically wipes the dalvik-cache folder anyway.
Unless there is something else related to dalvik that is outside of the /data directory.
Are/were you using a current version of CWM?
Is it necessary to do a cache, data and delvik wipe when I am restoring a back up?
I always have back up of different ROMs and very often I try out new ROMs. I always wipe everything but is it necessary?
Actually, so do I but I'm not sure whether we need to either! I just don't want to take a chance that a residual file screws something up...

If you are restoring from a nandroid, no it is not needed. The backup restores EVERYTHING data/cache/davlik/kernel/etc...
That's good to know.
I am restoring from the nandroid backup.
I've gotten alot of errors before when restoring a sense rom from an aosp without wiping... And by errors I mean it restored fine then was unusably buggy...

Just go into recovery wipe data and cache then restore. Its not rocket science.

No, it's not rocket science, but that's not what the OP asked.
It was a valid question: is wiping needed when restoring a backup, or is it a superfluous step? No need to offer a condescending non-answer.
For what it's worth, I don't wipe before I restore a backup and have yet to run into an issue. That's not to say I'm right; just that it hasn't yet caused me headache.
My two favorite roms are Fresh and CM6. I would like to be able to jump between the two whenever the spirit moves me. However, whenever I try to nandroid restore to a Fresh backup from any AOSP rom, i get stuck in a bootloop and have to rewipe and flash everything in order to get back, therefore making my Fresh backup useless. Before flashing any new rom, I always do a full data, cache, and dalvik wipe. I am I missing something here?? Shouldn't I be able to flash a rom (aosp or sense), get it setup with programs the way I want them, screens setup, etc. Then make nandroid backups and jump back and forth restoring them whenever I want?? Please help

You might be having the same issue I was; what recovery are you on? It happened to me when I was amon ra 2.2.1 so I switched to 2.3.1 amon and I stopped getting tons of bootloops. P.S I never have to wipe anything when flashing nandroids and never had an issue. My issue was the recovery.

I am currently running RA-supersonic-v2.3. Yesterday I did another backup of my most current Fresh setup but this time I also backed up the cache and sd-ext options in the recovery menu and I didn't have a problem nandroid restoring back after flashing an AOSP rom. I don't know, I think my phone is possessed!

In most cases I would agree, but if the OP is running any sort of ext a2sd, contents of cache/dalvik cache are not entirely restored, and clearing them after restore, but before reboot is a good idea.
I just ran aosp rom for the first time for a few days. When I nanded back to airborne (sense), I flashed a sense kernel before the nand restore just out of fear of remnants. Dont know if its necessary.

Whay exactly does a full wipe consist of? Using RA 2.3 recovery.
I usually wipe system, cache, and dalvik that way I keep all my dl app but some wipe data also. U can wipe boot as well.

A full wipe, in preparation to flash a new rom would consist of wiping:
data/factory reset
cache
dalvik cache
boot
system
I always wipe everything 2 or 3 times. I also flash Calkulin's Format All after wiping all of the above. That might be overkill, but it makes me feel better before I flash a rom, lol. You get a completely clean start.

What would happen if i wiped everything and rebooted? not that i wanna try it or anything just curious
My definition of a full wipe using amon RA is EVERYTHING in the wipe menu except the SD card and when I flash a different rom, I wipe everything on that list with the exception of the card itself. Technically speaking, however, the list that k2buckley posted is correct.

If you tried to boot after wiping what I mentioned, you will either hang at the splash screen or it will boot you right to fastboot (not sure really though, as I've never tried, but it wouldn't boot, for sure). Since it wipes system and boot image, there would be nothing installed for you to boot into. Btw, I would avoid trying that lol.

That's crazy. Wiping everything like that is over kill. No need to wipe data as its all the apps that uve downloaded from the market. The only ones really needed are dalvik, cache, boot, and system. And I've only ever had to do it one time then flash a rom and it works everytime plus I have all my data and apps there still

He asked what a FULL wipe was. Not if it was necessary or required. And not wiping data when going from one rom to a different one (not an update of the same rom, but to a totally different rom) has ALWAYS left me with weird issues, such as wake locks, cm Widgets on salvage mod, reboots etc.
Oh well, we all have our own methods and rituals for flashing, lol. I will stick to my methods, and everyone else can use theirs.

I'm guessing u know this but have u ever looked at ur data folder with root exployer or what ever. The app folder might have 5-6 apps in it and the app-private folder holds the apps u dl from market. So wiping it in recovery makes little sense. I've flashed plenty of different roms without wiping data and never had a problem. Plus on an upnote all ihave to do is flash the roms and gapps if needed and restart and that's it. No need to sit there for an hour restoring apps or settings

Useing CWM wiping everything clean to install a rom. At this point back up useing CWM. Now if I just restored that backup before every rom would that be like wiping everything for it?
rom install
If you don't perform the wipe before installing a different rom, all you are doing is installing over top of, and you can run into problems that way. The exception would be that some of the developers start the installation by formatting.

I get what your saying and its an interesting question..
RESTATED: WIPE EVERYTHING AND BACKUP THE WIPAGE....lol
So that if) t were restored, it would restore a blank...tricky to explain
Ok so imo, i dont think it works...i have zero base for my opinion. But even if it does work why? Wiping is faster than restoring anyway. Flashing TDJ's superwipe is even better and still faster than restoring.
Interesting question nonetheless

You want to backup before you wipe because if you backup afterwards you would be backing up either a blank ROM or by a small chance a wiped version of your current one.
