I guess sometimes we have to learn the hard way...stupid noob that I am. If I would spend more time reading before I jump in and make a change I think my life would be a lot easier. Flashed the update yesterday including the SuperWipe Lite and then spent all day reloading everything using Ti Backup. Got all my app data back but most of my settings and all of my widgets were screwed up.
So question is if I use nandroid next time, does it make the process of restoring everything easier? Or should I just skip the SuperWipe all together? I would love to play with some of the other ROMS but I'm gunshy now to try it.

If you're wanting to try different ROM a nandroid is not how to do it. Since a nandroid backup save everything "as is" at the time of the backup. So if you flash a new ROM and do a nandroid restore you're back at square one.
A nandroid backup is good if you want to try different things and restore back to where you were.
Titanium Backup is still the way to go IMO. I use it and restore only apps + app data. The Google account should handle the system settings.
Take me about 15 minutes to go from ROM to ROM initially.
Also when updating the same ROM there's no need to wipe (unless stated otherwise).

Flashing Question

I'm currently rooted running a MIUI ROM. My question is, if I want to flash to a different ROM, what do I need to do prior to flashing? Can I just flash directly over using CWM or do I need to revert back to stock first?
Thanks
If it was an update to the same rom then you could probably just flash over depending on the chef's instructions.
But a different rom, I would definite wipe data/factory reset it first.
Of course I would backup apps/data, and a nandroid backup too

Thanks for the reply, so would I need to unroot and reroot and all that stuff over again, or can I just choose the factory rest option from the boot menu?
There's no need to return to stock, just wipe data/cache from the CWM menu.
If I have a backup of of an existing ROM, and a Titanium backups of all apps and app date, why would I need a Nandroid backup too?

[Q] (Clockwork Mod) What is Nandroid Backup and How Does it Work?

This is a noob question, but I have a bit of experience under my belt just so you don't have to worry too much about using "confusing" terminology.
I have rooted/ROMed many devices in the past and have heard guides talking about doing a Nandroid backup. My question is how exactly does it work? Say for example: I am on the stock ROM (rooted of course) and I do a Nandroid backup while on stock. If go to say Cyanogen and I don't like it can I just restore from my nandroid backup like I would flash any other ROM to go back to stock. And if that will get me back to stock does it also preserve all of the user data that was in that ROM when it was backed up?
Any other information about about nandroid backups would be appreciated. Thanks in advance!
From my understanding, the backup backs up all the stuff on your phone EXCEPT for what's on the SD card.
The idea is that you do a back up. Then install a new rom that you want to try out. BUt you don't like it, so you just restore the backup and woolah! your old phone is back along with all your settings, data, etc.
I'm not sure why it's called a nandroid backup, but from what I gather, you can do it with clockworkmod, just boot into recovery. And use the backup and restore option.
That was my understanding as well. I just wasn't sure on the situation with the user data (or the backup in general really). So all it takes is a nandrid backup to revert back to (rooted) stock?
A Android backup takes all the files on your device and saves them as a data.img,system.I mg,cache.I mg,user data,and recovery.img. It is also restorable through fastboot. It can also get you out of a tough spot. Say you are messing with a new theme and it causes your device not to boot up or causes unwanted problems. You can restore a backup to a time when your device was working correctly.

this is true unless you do a nandroid+android_secure backup. this also backs up your external app data

Yes you're correct. You can restore but just remember some app might have ext data in sdcard. If you don't delete it, when you restore you'll get the same as before

So if you want to restore say just your data can you just delete the images you do not wish to restore from the backup folder and it will just keep the ones you have? Or won't it work at all if you start deleting images?

i wouldnt tamper with a nandroid backup, but if you have clockwordmod recovery, that is possible. clockwordmod recovery gives you the option to restore one of those images (but only one at a time).
does a nandroid backup include your kernel?

It does! It's a compelete "snapshot" of your phone with all apps/settings etc.
Does it also backup the stuff which has been stored on the external ext2-Partition, which is mounted to enlarge the space for apps?
Same with restore of this nandroid-backup. Will it also place the backup again to the same space?
As I know there's a (symbolic) link put into /data which might get problems.

Nandroid backups
I was wondering if the framework is saved as well. I recently updated to the ICS firmware and am wondering if I restore with a backup from the old GB firmware will that be restored as well or will it still stay on the ICS? From my understanding ICS firmware will run previous versions
will nandroid backup (made from cwm) un-brick your phone if say, you installed a custom rom via cwm and it bricked it?

Yes,It restores all data and apps nandroid backup is a mirror copy of your phone.after restoring you will get your previous stock ROM.

im not sure, i think nandroid backup will unbrick your phone as long as you can boot to recovery. atleast when i installed a roms pach it didnt fully boot, got stuck at bootanimation, no loop, just froze, then i got it back with nandroid backup

Can i restore a back up made under CWM from TWRP?
how do you restore the back up?
am i missing steps? Fix permissions?
do i need to recalibrate my battery each time?
Thanks
Heniki
You can only restore CWM backups with CWM and TWRP backups with TWRP. As of now CWM 6's backup function is broken but it is being worked on. So make sure your Backups are from either TWRP or CMW 5 if you want them to work.
To restore a backup I wipe data/factory reset and wipe system. Then choose the backup I want to restore. No need to fix permissions unless things start to act funny after the restore. As far as battery calibration goes it's a myth.

With R6, Bryan said he fixed the backup and restore issues with CWM6. Idk about the rest of the features
When you say "Cyanogen" I think many assume you mean CM9 (ICS).
If you are running CM7 (GB), be very careful how you restore. Most system data (and perhaps some user data) from GB is not compatible with ICS.

As Fb said in the post you linked you flash the boot.img that came with your rom or reflash the rom.
The more times you flash roms the more issues you could have with "gremlins". Read more about it in the link.

Restoring Data From Nandroid Backup.

Earlier, I was on the Elix-R ROM. I was going to upgrade to the newest version of it and made a nandroid backup but forgot to make a TiBu of all my apps. Would it be safe and possible for me to restore all of my app data from the nandroid backup by doing an advanced restore of my data?
you were upgrading the rom that you were using.. why would you wipe data?? if you are upgrading a rom, you never have to wipe anything. all you do is flash the updated rom(and gapps) on top of what youre running without wiping anything.

also, another question: should making a TiBu and then erasing the system to flash a new ROM affect the backup of apps or no?
You could practice restoring your nandroid backup, then 'dirty' flashing the ROM upgrade straight over the top.
Once you get used to it, dirty flashing isn't so bad. Saves a ton of time. Plus you have the nandroid just in case .
In answer to your query though, you can extract apps and app data using the appropriately named Nandroid Manager. I used it before on a now sold Nexus 7 when it decided to not boot up but could get to recovery and make a backup.

[Q] General Nandroid question about restoring a backup and custom kernels

Hi
I have a couple of questions, been digging around xda and the web and found some conflicting answers...
1) Does a Nandroid backup also back up the kernel? I'm thinking about dabbling with some custom kernels, but don't want to potentially mess things up as well as have an easy way back to the stock kernel if I don't like the custom one for one reason or another.
2) What would happen if I made a Nandroid backup from recovery, did a full wipe (/data, /system, /sdcard, caches), rebooted then restored from the Nandroid backup?
I'm still pretty new to all this but I've done some reading and a wee bit of flashing & rooting on Nexus devices and the HP Touchpad. I also have an old TF101 that I'd really like to tinker with as well.
Thanks!

I don't know much about kernel but I do know that Nandroid backup backups everything exactly where the phone is.
That means if you do factory reset and restore Nandroid backup it will restore everything from the day you made the Nandroid backup.
I hope it clarifies everything.
Let me answer your questions.
1. When you do a nandroid backup, it backs up everything. Including the kernel.
2. If you nandroid backup, factory reset your device then restore your nandroid backup. Your device will return to the same state you had it previously. You will have all your content, files and settings. However if you do a backup, then factory reset and reboot, your device will be wiped of everything but it will boot up. As if the device was just turned in upon purchase. Also note, if you do a backup, then wipe your device (factory reset) you will not lose your backup.
Just note, if you ever flash a ROM, even if the developer states there is no issues. MAKE A BACKUP, sometimes things go wrong.
Happy flashing

Thanks for the quick replies!
I was a bit confused about 2) because I read somewhere that if you make a nandroid backup of a stock ROM, then install a custom ROM (non-Stock based ie CM, PA or OmniROM) you must flash the stock ROM again before you can restore the nandroid backup, or else restoring the nandroid backup will not work. Is this true?
Consider the following example, say I:
-flash TWRP on my device and root
-make nandroid of stock, rooted ROM
-wipe /data, /system, /sdcard and caches and reboot back into recovery
-ADB push a non-stock custom ROM .zip file and flash the custom ROM
-decide I want to return to stock, rooted ROM after a while
-Boot into TWRP, then wipe /data, /system, /sdcard and caches and reboot back into recovery
-ADB push my original stock, rooted nandroid backup to /sdcard while in reocvery
-restore nandroid backup
What would be the outcome of the above example? I'm very curious...but I'd like some advice before attempting something like this myself as I'm still kinda new to all this
BTW I'm now comfortable flashing back to stock using fastboot and the google facotry image to restore a Nexus device so I now know how to do this in case things go south. I'm just curious if this would work on a device where returning to a full stock state isn't so easy.
No you don't need to install anything to get back to the previous state. So if you had a stock rooted ROM, then backed it up. But you decided to flash, let's say. Cyanogenmod but you wished to return back to stock, you don't need to flash stock ROM, all you have to do is just wipe data and restore your backup.
And for the example.
The outcome would be, you would be resulted with a stock, rooted rom.
