See this thread in the Development Forum for Corn Kernel... It has a working nandroid. BTW, that kernel is for i897 Gingerbread Roms.

Question Components backed up by nandroid

Thanks for sharing the knowledge.

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.

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,

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...

If you don't read the forum, why should the forum read you?

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)?
