Hi all, just a quick question regarding Nandroid.
If I have two Motorola Milestones, both running the same exact firmware with the same baseband and everything (i.e a one-to-one copy), then if I make a Nandroid backup on one of the Milestone, will I be able to restore using the same backup on the other Milestone?
e.g. If I make a Nandroid backup on Milestone #1, can I use that backup on Milestone #2?
In other words, are Nandroid backup device specific, or do they work across the same phone as long as it runs the same firmware and baseband etc? I ask this because I noticed that there's a MD5 checksum used in the Nandroid backup. Surely that is used to verify the device or something?
The main reason I ask is because I need to restore the Milestone from one of the Nandroid backups I made. The problem is, the newest backup couldn't be restored properly. Well actually, it does restore and the whole operation completed successfully. But during one of the backup steps, it showed a "MD5 checksum mismatch", therefore not everything was completely restored.
However, using an older Nandroid backup restored completely fine, but of course it's a lot older from probably 2 months ago. Both backups were made on the same device and were backed up successfully so there shouldn't be any problem.......
So now, I just want to test my newest backup on another friend's Milestone, which has the same firmware/rom and baseband etc as me. I just wanna test it since that backup is very important to me and I wanna see if I can at least try to restore it somehow.
MD5 is used to check file integrity
the backup itself it's done from what i get at a partition level so meaning it restore partition at date of backup.
about the firmware
if you have different firmware versions after restore you have one version on both if u restore only data partition, you have to have same firmware from the same developer, and usually works.
yes it should work on every milestone.
I see, thanks a lot!
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

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 all
After smashing the screen on my Note i am getting a new one on the insurance, well i am when they decide to deliver it!!!
just want to know if it will be ok to root and restore my backup from the old phone?
i was running criskelo v9.1 at the time with speedmod kernal i think
big time
Are you talking nandroid restore? If so choose advanced restore and restore system and data only this will restore the rom and your apps anything else might cause issues, like restoring old imei and stuff.
Or you could extract certain things from the nandroid using titanium backup or similar app
Sent from my GT-N7000 using xda premium
i was using cwm for my backs/restores before and i desperately need my notes and phones off the old backup.
wouldnt the imei coarse problems?
you will get all your notes back with the data restore.
It might be safe to restore the whole nandroid but i wouldnt advise it, Personally ive never tried so hopefully someone who has can confirm ?
your imei from your old not wont replace the new one, But it could modify it and leave you with the samsung generic one.
thanks for the help, hopefully i should have the phone by saturday and get testing....
Seems like there's some new custom ROMS for this device but, we need to make IMEI backup, i've been searching tutorials, but can't find anything about this device, i won't try anything since it is needed, someone knows a way to make a backup and if anything happes there's a way to restore it.
Here's the guide: https://forum.xda-developers.com/t/guide-how-to-backup-imei-in-pbrp.4363647/#post-85963995
I have two GT-I8190s. I made a backup via TWRP of everything on the old phone (EFS included) and I just transferred everything to the new phone, this means that the original EFS on the new phone has been overwritten by the old phone. I just wanted to have a one to one copy and didn't know about the partitions and their meaning, and that TWRP can practically flash the EFS partition. But I have a functional IMEI that matches the sticker, but no CSC, even after I have flashed a stock rom. What can I do to get the original EFS back as much as possible?
