How does NANDroid backup work? - Verizon Samsung Galaxy S III

I'm just wondering how the nandroid backups work.
So i'm backing up my current rom (aokp m1)
If I wipe everything and flash to something else and i don't like that rom, can I just wipe all data, cache, dalvik and then just restore from the backup? Will everything go back to normal?
Thanks!

Yes you can quickly and easily revert to a previous ROM. Wiping of caches isnt necessary because they are restored as well.

So pretend I go from AOKP to XYZ ROM and I don't like XYZ, I can just wipe data and then use the backup to restore and it'll just be the same old AOKP?

yes....and if you keep 10 different roms all backed up, you can easily flip between the different roms by simply restoring their backups

wipe everything

[Q] When flashing a rom

I am confused, do I wipe data/factory reset or format data???
Backup only user apps with titanium backup, run nandroid backup, wipe cache, wipe/factory reset, flash rom

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).

Thanks

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.

I always prefer doing clean flashes of all of the ROMs I run.

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.

Yes. Its the same as having never wiped in the first place

Anyone else flashing ROMs and finding them sluggish?

I used to flash things like Liquidsmooth and my phone would fly. Now when I flash GPE or a CM based ROM, it hangs and lags sometimes. Anyone have any similar problems?
Would also be a good time to ask, will wiping internal storage in TWRP delete recovery so I can't flash ROMs?

No issues here... To answer your question... no It will remove your backups if you stored any there. Once you have installed twrp it will always be there unless you change it.

That's your whole problem right there.
You are reluctant to wipe /data? You HAVE to do it if you go from one rom to another. Also called a clean install.
If you go to the Wipe menu in TWRP and just swipe the button it will wipe cache, Dalvik and /data except /data/media/ which is where your personal files live. It will wipe you apps and their settings, but you can backup those in TiBu and restore them afterwards. Do not restore system settings from TiBu though!
Give your phone a break. Do that factory wipe I described above, then re-flash your current rom and I can pretty much guarantee it'll be night and day.
This phone is so fast - a shame to gum it up

Restoring Nandroid beckup

Hi,
I have a general and simple question.
Last week I changed to paranoid rom and I want to return to 11S rom.
If I'm just restoring the nandroid backup and wipe catch and data it is as the same as fleshing it new?
thanks!
Not really,
Anyway, since you gonna wipe data anyway,
Why dont you just flash the whole new rom altogether, instead of nandroid rstore,
Wont take u longer either
It's just easier to do(no need to root again and open the bootloader and recovery) !
Anyway, when I'm installing new rom it will erase my internal storage or just the data/contacts etc.?
thanks!

There's no need to flash the ROM from scratch, a nandroid restore is perfectly fine.

Just go ahead and restore your nandroid backup, it's exactly what they're designed for. The process should wipe the necessary partitions for you but I always wipe system, data, cache, and dalvik cache first anyway just to be sure.
And no, installing a ROM doesn't erase your user data unless you do it yourself. Erasing the data partition only erases apps, settings, etc.
