what is a nandroid? how do you perform a NANDroid backup of your current ROM? im going to cm7 stable from kj1. just wondering cause it says in the steps to install cm7. thanks..sorry for the noob ques..
its making a complete backup of ur current rom settings,apps and all. with i897 gingerbread roms i dont think u can restore a nandroid backup. but u would normally do a backup in recovery with cwm.
yes, nandroid on i897 ginger roms do not work.
but the procedure would be to make a backup. then if you flash a different rom from what the backup was made from you would have to flash the rom back that was backed up THEN restore the nandroid and it will be like you never flashed away from that rom.
DO NOT EVER restore a nandroid to a set up it was not backed up on, it will bootloop.

can you expound on that please...hahaha..sorry im reading it over and over..just need to clarify..what you mean? thanks btw guys for the reply..so basically nandroid backs up your rom..cause just the name sounded confusing..i mean why name it nandroid when they can just say in the intructions before flashing a rom to just "back up" your rom..haha..i thought nandroid was something else..cause i heard other people saying something about efs or whatever and backing it up but i dont even know what that is especially..thanks though for replies..got it..
Say you back up your current ROM, then flash another. You can't just restore ROM A onto ROM b. You have to flash back to ROM A and THEN restore the nandroid and it will be like you never flashed ROM b. All of you settings and everything will be intact.
Efs is totally different, that is a partition that contains your phones individual data, it's imei which you have to manually backup it's not included in a nandroid.
Components backed up by NANDroid
Which of these components does NANDROID back up?
- bootloaders?
- kernel?
- system apps and other apps?
- modems?
- other parts of the OS?
Thanks for sharing the knowledge.
The firmware and system settings.
No kernel
No bootloader
No modem

Kindly clarify this please, i want to backup my stock rom before going custom.
So inorder to do a complete backup, we need to do a nandroid backup and also backup imei separately?? and then restore both of them when i flash back to stock??

They are two separate issues, really, but you are correct that you should back up both.
Nandroid lets you go back to a previous state, as long as you flash back to the correct ROM before you restore it. It will not let you restore data to your new installation, though. If you want to restore your applications in your new ROM, you can download Titanium Backup from the market which will let you batch save your applications now and restore them on your new ROM (It can also save and restore system data, but don't restore system data between ROMs, it causes all sorts of weird issues).
Backing up your EFS folder is something you should do, but hopefully will never have to restore. Your EFS folder contains information about your phone and should never actually get touched in any way when flashing ROMs. However, things go wrong and sometimes this folder ends up getting corrupted for whatever reason, which can lead to a corrupt IMEI code and no service. If this were to happen, you would restore you EFS from backup. I think it's safe to say most of us have never had to actually do this, but better safe than sorry. You can do a search for backing it up and find several threads about it.
Happy flashing!
lol...I was about to do nandroid backup! These post wre real helpful...thank you!
See this thread in the Development Forum for Corn Kernel... It has a working nandroid. BTW, that kernel is for i897 Gingerbread Roms.

When I run a nandroid backup I see it processing these:
- boot image
- recovery image
- system
- data
- datadata
- .android_secure
- cache
- sd-ext
Can anyone explain some of these terms to me? I am pretty new to all this.
This thread has all the goodies defined pretty well http://forum.xda-developers.com/showthread.php?t=1093062
Guys , if I have two same model phones , one with alot of games and modded ROM and the other is standard , Can I take NANDroid backup from the first and restore in in the second ?
thanx in advanced

You will need to first get it on the same modded ROM and then flash the backup. They will then be identicle
Hello,
This is the thread I was looking for. It just tackles top backup/restore issues I want to be positive of before tinkering around.
Now, what app is capable of doing a nandroid backup, if any? RomManager?
If a nandroid backup consists of the firmware and system settings but no kernel, bootloader or modem, how are these three backed up then?
My goal is making a stock unrooted (if possible) backup.
A concerning restoring, from this thread I understand that the restore process is composed of:
1st restore ROM A (which?)
2nd restore nandroid (which?)
3rd restore data/apps (Titanium is able to)
4th restore EFS folder (how?)
Please, correct/suggest. I appreciate.
Greetings,

First of all, you have revived an old thread with now false information. A nandroid does include modem and kernel. Bootloaders can't be backed up, and there really wouldn't be a point in that. No app can do a backup, and please don't use ROM manager; it's obsolete. As for your steps: You probably only need to flash a ROM first if the partition table is being changed. Meaning you can't restore a Samsung ROM over an AOSP ROM. You won't need to use titanium backup because you will have restored the phone to the exact state it was when you took the backup. Meaning there won't be anything to restore. Efs? Don't touch it, we never will be deleting it.

Modems and kernels ARE NOT backed up in a Nandroid...
Hello,
@korockinout13: I don't think I'm providing false info. Actually, i've been gathering from the thread. I think there's some disagreement on what a nandroid backup really backs up from the views expressed in the thread. Plus, it's pure netiquette not opening new threads for a topic already started somewhere else in a forum. It's power ecology. No hard feelings, though.
Thank you and b-eock for your replies. I think I'd rather use cwm instead.
My goal is still the same: making a stock unrooted (if possible) backup as there are no roms available for my brand new Mini:
pda S5570XWKQG
phone S5570XWKQ5
csc S5570YOGKQ3
android version 2.3.4
Kernel 2.6.35
Thank you both!

Someone told me about the modem part, so I'm not really sure about that. But if it doesn't backup the kernel, why does restoring a nandroid put you back on the kernel you had previously (i.e. Glitch)?
Hi , some questions.Will appreciate if anyone could take the time and answer.
1. What things are left out in a nandroid backup? Are kernels included?
2. I can't restore a nandroid backup of froyo on GB without flashing a stock froyo build first, is that right?
3. Can I restore a Nandroid backup of GB 2.3.3 (say) while on GB 2.3.7 or any other 2.3.x? If yes, what if I am on different kernel than the backup kernel, can i still do it?
4. Suppose I am on 2.3.x based custom rom (say MIUI) and I restore a 2.3.x based CyanogenMod Nandroid backup, will I get my whole CM back or all my apps/settings of CM on MIUI?
Thanks a lot.

I'm not sure I can answer all your questions but I'll tell you what I've done.
From stock, after making a nandroid backup using CWM, I've flashed a CM7 having done all the usual wipe(cache,etc) procedures and gone back to stock using the backup. Everything is restored, including my settings, old messages, kernel, apps, everything. Be warned, you will obviously lose all the messages and call records that you received after you flashed the new ROM, unless you use an SMS/call log backup app. Same with CM7 to CM9 and back. So if you plan to flash a new ROM, the nandroid should be able to get you back to the exact same state that you were in when you made the backup.
I'm not much of an expert though, so I might be wrong. Feel free to improve on this answer!
1) Yes
2) Yes. Because of change of Linux kernel version.
3) Yes.
4) You will get whole CM back!

Thanks a lot guys...
One more question.
As you said, since I can't restore a backup of froyo on GB (because of linux kernel change), how can i restore a 2.3.x with a different kernel on a different 2.3.x with a custom kernel. Or is this kernel different from a linux kernel?
Asking because you answered the b part of 3rd question as yes (or maybe you didn't answer it at all, i am implying here)

Since GB to froyo is not allowed then CM9 (ICS) to CM7 (GB) should also be not allowed? Just want to clarify, have you restored CM7 backup on CM9?

Cm9 for the Ace still uses the old 2.6 linux kernel(same as the gb kernel) because linux kernel 3.x of ICS is difficult to port for our device!
I have restored a CM7 nandroid backup from CM9 and CM10 and it works perfectly!
Any Gb to gb rom restore works.

Cant restore my contacts,sms,apps and data from Gingerbread nandroid backup
Hi,
I have a similar problem.
Thought of posting a new thread but afraid that i would flood the forum.
I have taken NANDROID backup of my Gingerbread Stock ROM(rooted) using CWM.
Currently im in Cyanogenmod 7.2 for galaxy ace S5830.
I thought of restoring my Contacts,Sms,Apps using Advanced restore from Recovery mode.
Result: "MD5 mismatch" hence unsuccessful.
I tried restoring my Entire NANDROID back up.
Result: The Ace was stuck up with Samsung LOGO.
I flashed CM7.2 again after restoring factory settings.Things work but a blank phone.
So im in 7.2 again. How do i restore the GB Rom? I just want to safely export Sms,contacts and data using .APKs and retrieve back in CM7.2 ????
(BTW CM 7.2 gives me 2 days battery backup at 480 Mhz (underclock) with many useful apps customized as ROM. Quite Delighted. Thanks to Mclaw)
Custom and stock roms use different file systems. Custom uses ext4, stock uses rfs. You need to convert file systems before restoring backup.
Ways to do it:
-flashing stock firmware with odin.
-using the cf-root ext4 manager app, which you can extract from cf-root flashable zip.
Good luck
Hi - probably a dumb question but I want to be sure it's safe:
Say I install and root and older GB ROM & kernel that can be rooted easily using zergrush or whatever and make a Nandroid backup of it.
Then I install a newer ROM, say ParanoidAndroid JB and root it and make a backup of it.
Can I safely restore the GB and JB roms without any issues - especially bricking obviously but barring that will both roms function fine?
Thanks - please only answer if you are sure! Thanks.
Yes.. No problems at all. Just make sure the kernel you on should be safe.
Thanks for the reply.
Does it matter what version of Recovery (CWM etc) I have - is this completely seperate from ROM/kernel that's installed?
Cwm can only restore Cwm backups... Unless modified. Also sometimes backups made by newer version of Cwm may not be compatible with very old cwms. But I have tested the backup made with a new recovery Cwm and restored it with abyss kernel so it's okay.
if i'm from cm11 can i make nandroid backup and i'm back to stock rom and later i restore the backup
will i get my cm11 like before with apps and data
