Can't seem to find a topic about this aside from people saying always make a backup.
So anyway I poopooed it and flashed a custom Rom without making a backup of my stock Rom is this bad?
Or aslong as I have a working custom Rom backup I don't need to worry about it.
Sorry if this is a total noob question but I am a recent apple convert so still new to this.

Bump anyone?
All the kind of backup you're talking about needs to do is work, you're not backing up a specific configuration or any specific data and thus it's not necessary for it to be stock (although people backup stock just because it's the base vanilla and unmodified version of Android), all the first backup you make needs to be is something you can fall back on if your current setup stops working. Having a working backup is always useful but as to whether you have "poopooed" anything by not backing up stock, if the current ROM you're on is working and ideally has a stock Kernel then simply back that up and nothing will be "poopooed", everything will be weeweed.
Thanks for reply, I figured as much but still wanted to be sure.

First, I have to thank the XDA forums helping me come over from my long WinMo background. Mad Props...
Being new to Android and my nexus one, I'm feeling the ROM flashing bug and want to try out a couple of different ROMS but don't want to have to add all of my accounts each time since I use crazy long, nearly impossible to type, passwords.
Is there some way to restore some of the configuration of my N1 between different ROM flashes?
Sorry if this has been covered, but I can't find it. It looks like the data is backed up in my nandroid backups, but I can't seem to find out how to only restore configuration.
Thanks

Take a look at Titanium Backup.
It works really well.
You need to be rooted and superuser in order to use it.
To find out more about adding superuser to a stock ROM, check out this thread at Modaco.
Edit:
Nandroid backups are really "just" disk images afaik.
There's no way that I know of to extract information from them.

Ok, thanks. I am running the backup right now and will give it a try tonight. Worse case, I just restore the nandroid backup and try again.
I've always wondered, what stuff is safe and not safe to restore in Titanium Backup. I've done a full restore when switching between like roms, but I'm guessing that wouldn't be a good idea if you were going from cyanogen to a senseUI rom.
Hi all
Is Nandroid backing up all the apps I've got at that moment? Or it just saves system files?
Like a complete and exact "photo" or are there things that I should do on my own if I mean to recover exactly as it was...
I assume that no wipe is necessary...
Thanks!
What's the truth about Nandroid backup?!
i guess there's no need to open a new topic, because i got kinda the same question
before you guys start to redirect me to the "search" function, i want to assure you that i have been using it, but i have found myself in a very strange situation, one question, two different answers... and because i'm new to the whole root stuff, i want to learn everything correctly before starting to make modifications to my phone
The question is: Nandroid backup, does it also back up the kernel or not?
I mean, if i root and install a custom rom that also comes with a custom kernel, will i be able to use my previous Nandroid backup to restore my phone to the old rom & kernel?
Searching the forums, i have found 2 totally different answers!
Answer 1: Nandroid does not backup the kernel: http://forum.xda-developers.com/showthread.php?t=806340
Answer 2: Nandroid does backup the kernel: http://forum.xda-developers.com/showthread.php?t=844352
So, please make me and all of us root noobs understand once and for all, does it backup the kernel or not?, will we be able to restore from a custom rom+kernel in case we need to?
and does it backup apps?
OK...As I understand it....
What does Nandroid Backup?
The ROM Itself..Obviously.
All your system settings, emails, SMSes, etc
All the Apps you have installed, so no need for TB
The Kernel you have installed (though there is controversy about this, and to be honest, I have never restored a nandroid backup when I had a different kernel already installed...however it really doesn't matter since kernels are easy to flash)
What does Nandroid NOT backup - This is VERY IMPORTANT
The modem (not a big deal)
The File System setting (A BIG DEAL)
This I think is where the confusion arises concerning the kernel being included in the nandroid backup. For many people the kernel is all about the lagfix. If you have installed a lagfix on your phone via the kernel, say changing the file system to Ext4, and then flash a Nandroid backup that includes a stock kernel or other kernel that does NOT support Ext4, you are in for a world of hurt...and in this case hurt means endless bootloops.
The way you avoid this is, if you need to flash a Nandroid with a kernel that does not support your lagfix...go into recovery, disable whatever lagfix, tell it when it asks that you wish to REBOOT INTO RECOVERY after the change....then flash the nandroid you wish.
This is why it is very important to keep regular nandroid backups, and to wait and see if a ROM/Kernel are stable for you before applying lagfixes or other tweaks.
So, let me see if i got this right, Nandroid does backup up my current kernel along with my rom, but if i apply any changes (lagfix) to my kernel afterwards or change it with a custom one with lagfix, nandroid won't be able to restore it anymore...
so the whole problem here is that nandroid is not able to backup / restore The File System setting, this being the rfs / ext4 transition
If this is the case, it seems that the Nandroid type backup is not as powerful as i thought, you can't really change from one rom to another in just a few clicks, but then again i guess that all the customs roms already come with some type of lagfix and you can make a nandroid restore between them, the problem would be when you want to revert back to a stock kernel, then you'll have to disable the lagfixes or simply flash a stock kernel and then restore the stock nandroid backup
so, i got this right guys?

Yes as I understand it.
You see Nandroid can't convert your file system or change anything, all it can do is flash a disc image onto your phone. If that image can work with your file system, you are golden. If not, it is like flashing a Mac OS image onto a Windows machine....nothing will work right.
However the good news is that most custom kernels support Ext4...so really the only problem comes when you try to flash back to a stock image...or vice versa.
got it then, thanks for your answers
and, if i still got your attention, maybe one more question
i just downloaded a stock firmware from samfirmwares.com, and all i got is a .tar file, can i use it somehow to flash just the kernel from it or i have to flash the whole firmware?
if i flash the whole firmware, will it also change my PHONE and CSC?, because the .tar file must be put just in the PDA section in odin

Yes, it will flash the PDA, csc, modem and kernel...the whole shooting match. The single file firmwares are designed like that to avoid mismatches and issues. Once you flash it, flash a kernel that supports cwm (I suggest speedmod or something by CHAINFIRE) via odin, then flash a new csc and modem if you wish from recovery.
Remember that installing a new csc will do a factory reset so do it before reinstalling apps.

great stuff man
finally i got enough info and i can start my root & flash procedure, guess i'll also learn a few other tricks along the way, this community is definetly the place to be if you want to learn how to "really use" your device
the whole info about the issues with the Nandroid type backup should be integrated in one of those massive info topics, so the root noobs like me know what they're dealing with

Hey guys i actually used the search button (yay) and this is definitely the most informative one regarding the topic.
However i still have one more question: does it backup files and folders as well? Ie. my Nexus S storage is mainly used up by my videos and music (about 7-10GB) which are in their own folders and not tied to any apps in particular. Hence if it does include those i wouldn't have enough storage space to create a nandroid backup am i right?
Edit: thanks to the search button i didn't realise that i posted on a Galaxy S forum please forgive me, the question should still be relevant to the topic though

As I understand it, it does save folders and files, so yes if you have large data folders on your internal SD it will make GIGANTIC nandroid backups. You may want to store such files one your external SD.
I know that there is a version of CWM that does not backup /data/media in Nandroid on the Galaxy Tab 10.1...perhaps there is something similar that I don't know about for Galaxy phones. Does anyone know?
Hello guys,
I bought SGS1 a while ago and changed some roms it was annoying losing my apps then my friend told me to use titanium backup it was more annyong cuz i had to backup one program at a time
then i heard about Nandroid Backup , so my question is:
if i change ROM lets say from MIUI to Darky or something and i used Nandroid Backup, all my apps will be there after i restore?
Your phone will shift back exactly where it was when you nandroid backed up ! And any progress from their will be lost !

So if I change rom from miui to brand new one and then i restore it will go back to miui? or it will just put my apps from miui on the brand new rom?
Its backup whole rom with apps...tge best possible solution is u have to use titanium backup pro it make a complete backup of apps....i thinkn u r using some free version pf titanium thats why i makes problem.

Titanium Backup offers the option to backup all your apps at the same time, in case you didn't know. This may be only for the paid version though, I'm not sure. But considering it's the most useful app I've come across, it's definitely worth the money.

Actually if you try to restore a nandroid backup after switching to cm7/miui, your phone simply wont work as the file systems are completely different.
To go back to a Samsung ROM from miui you would need to flash a stock Samsung ROM via odin, and THEN restore the nandroid.
Anyway, beyond that remember the following...
Titanium backs up apps and app data, use after changing ROMs to regain apps.
Nandroid takes a snapshot of the entire ROM, use in case of problems to repair your phone.

Correctly said rschenck!!
Basically if you are on CM7 and want to give a try to MIUI just make a NANDROID backup for full ROM backup and try MIUI ,if you don't like it then flash back CM7 first and then restore the NANDROID backup!!
when it comes to Titaniuim backup , it backs up your app data,freezes them and the apps you want (only in pro version) on any ROM and restore back after flashing any other ROM, if you are on free version then you must select manually which apps to backup that's a pain in the ass !!
Use these according to your requirements....and dont ever restore one rom's nandroid with another as the Kernels,Filesystems,Modems,Bootloaders are entirely different and that could mess up your phone !!
i would prefer NANDROID over Titanuim !!
Thanks guys for this wonderful explanation...just one more query:
I'm currently using samsung Stock rom, CF root kernel, with lagfix(ext4), and some "framework" tweaks..and am thinking of trying CyanogenMod. So if i do a Nandroid backup now, and later decide to come back from cyanogenmod, can i just use Odin to get to ANY Stock rom so that the partitions, file systems, modem etc get back to a similar old format, OR do i need this exact Stock rom version, Kernel, lagfix etc before i can restore the nandroid?
is "kernel" included in a Nandroid backup? also, are Types of filesystems included (or "Lagfix" has to be repeated)?
hello guys
i am new to the android world and i am having alot of fun using it
its simply amazing and i decided to go further with new roms
i started by rooting my SGS and i had alot of features after that
i saw ics and am disperate to install it but am afraid
the point is i don't have any experience in android or programming
so plz answer my questions:
1-can i pack up the stock os from my mobile in order to return back to it in case anything goes wrong?
2-what is the difference between kernel and ios?
3-can anything wrong in flashing a new rom cause device hardware mulfunction?
thank u in advance hope someone answer me ASAP

1- you can revert back to your stock OS by doing the nandroid backup before flash to other custom rom.
2- kernel and iOS is totally different things. iOS is an OS use by Apple. Kernel is a core that provides basic services all others parts in operating system. OS is a set of program that manage computer hardware and provides services for application software.
3- You must bare your own risk to flash your phone coz bad thing may happen. But if you follow the instructions properly, it won't have any problem.
thx very much but i didnt mean ios from apple i ment the difference between a kernel and a rom
and for the nandroid backup is it a software? does it have anything to do with titanium backup?
thx again
my understanding of nandroid backup is it sits on the recovery menu. it is found on most custom kernel here on xda. it backup your entire phone except those files found on sdcard. titanium is mostly for apps
if you want to try another rom, it is best you use nandroid, just in case you want to revert back
Nand backup is accessible using the recovery menu. but from what i can tell some recovery's wont accept backups made using different recovery's. it is a direct copy of the memory stored there. unlike titanium that backs up the .apks and what not.
roms contain kernels and modems and the android operating system. but there are kernels that you can use that are not stock and can be installed/flashed using the same method in the recovery menu. they are interchangeable as long as its compatible with the rom. same i believe goes for modems. usually if you search the forums, any Samsung based kernel will go with any Samsung based ROM. same goes for asop/CM7 i believe.
I'm new to this whole thing, as anyone who saw my last thread I made a really dumb mistake and at that point I've decided to make sure I know 100% what I'm doing before I attempt anything else.
Anyways I have a rooted HTC One, still have custom recovery, I think what I had flashed was a stock ROM but I was looking into trying another ROM. The thing is I don't want to have to redownload and re-install all of my apps and whatnot again as that was a pain in the butt. I know there's backups and whatnot through TWRP and Titanium, but do they carry over from ROM to ROM or are they specific to a certain ROM?
Or am I completely off base with this whole assessment lol. I'm trying to learn all this stuff but it's definitely a lot of information to take in and I don't want another fiasco like last time
You can use titanium backup that way you can bring your data with you but restoring data can cause lag and other issues. That's why I just reinstall them all one by one I actually enjoy the process of setting up a new Rom. It is not Rom specific at all. Also check out SMS back up & restore. With that app you can even save your texts.

Good stuff thanks for the help man. I'll probably experiment with it a bit later but will probably just do a clean wipe to be safe
If you are flashing a rom with the same base that you already have (eg. both sense roms) you can try a dirty flash and you wont loose anything except your widgets on your home screens, I do it all the time bit it does not always work from one rom to another, ALWAYS make a nandroid backup before you flash anything!!! just in case.....
