[Q] How to Nandroid Backup

Running MIUI and want to check out CM7, I've never done a Nandroid backup ever, so what should I backup when it prompts me because I tried but wasn't sure what to select

thank you sir!

You only NEED boot, system, and data. Android secure is your apps, but I always backup and restore from titanium, so no need if you do that. Backup your wimax and make a separate backup of it as well, and copy it to your pc for safe keeping.

So is this what I would do still if I was running a sense ROM with dark tremor a2sd? And just wipe the ext when I flash a new ROM ?

Correct, do the wipes I listed previously, and the sd ext [if you're partitioned].

No intentions for redundancy, but just adding my 2 pennies. I prefer Amon Ra Recovery and withing the Bootloader screen go down to recovery which is under fastboot, then you should be directed to the Recovery menu, there you should see an option labeled Backup/Restore, within this folder should be an option labeled nandroid backup. Cheers to your successful backup.

Okay, thank you good sir

Personally, I backup everything except cache. I want the restore, when I need it, to be complete, and it's worked out that way every time.

I also store all my Nandroid backups to the PC, just in case sumthin' happens to the sdcard

How can I back it up before installing a new ROM? I want to install juggernaut, but I don't want to erase all my data! Help! Please?

Go into recovery and run a backup
That will back up entire stock rom
I suggest doing this
If u want to back up ur personal data n apps use titanium backup or MyBack up pro

You are in the wrong forum buddy, this belongs in general. To answer you're question. You need to boot into recovery, under backup and restore you are going to select backup and this will create an image of your current rom or stock os. It's like taking a picture that you can restore if you don't like what ever rom you flash. It even copies text msgs and apps.

CWM saves to the SD card - which isn't touched in a factory reset

[TUT] What Is Nandroid And How To Use It [Complete Guide] [VeNuM]

If you are new to Android, you probably have seen the term Nandroid used. If you are rooting your phone for the first time, or even an old crusty flashaholic, a Nandroid backup could be the difference between saving your phone or have having a $500 paper weight.
What IS a Nandroid? It is a full backup of the partitions on your device’s NAND flash (NAND actually stands for NOT AND,which in simple terms means an electronic gate). Basically a backup of your phones hard drive if you will... The Nandroid backup is a snapshot of your device (it means everything on your phone – your apps, data, your current ROM and even the kernel is backed up) at the time you do the back up. If you restore the back up, it changes your phone BACK to that state. You will need clockworkmod (CWM). So make sure prior to this you have CWM on your device.
Your SD Card data is not backed up in the process. Although the Nandroid backup itself is created on your SD card. Make sure you have enough space on your SD card to make a COMPLETE copy of your phone. It is highly recommended that once you have done a backup, you manually copy it to your computer in case your sd card is wiped or corrupted..
Pre-requisites:
1. Rooted Device:
You need a rooted android device.
2. Custom Recovery
While the OS is running you cannot do a backup. The boot loader in the recovery enables you to take a backup of the OS while it’s not running.
ClockworkMod (CWM) recovery is the example used in this tutorial.
Steps to Make a Nandroid Backup via CWM:
Backup and Restore via CWM:
1.Boot into Recovery.
2. Select ‘Backup and Restore’ from the recovery screen.
Once you are in recovery, scroll down to the option ‘Backup and Recovery’ and select it. You can scroll up/down through the menu using the volume buttons and select options using the power button.
3. Start the backup.
Once you are on the Nandroid screen, select ‘Backup’ to start the backup process. You have the option to restore backup on the same screen.
The backup process may take a while. Be PATIENT.
4. Transfer the backup to your computer (optional but recommended).
Once you reboot, you can see the backup in the ‘clockworkmod/backup/timestamp’ (or similar file) directory on your SD card.
Move, copy, or paste this folder on your PC safely.
It’s THAT simple…
Restore from a Nandroid Backup via CWM:
1. Boot your device into CWM and navigate to the Nandroid screen.
2. Choose ‘Restore’ and begin the process.
If you select ‘Advanced Restore’option, you may select which part of the backup to restore – i. e. the boot,system, data or cache. Or choose the whole backup.
3. Reboot your device. Your system is now restored and is exactly the same as the time when the backup was taken.
Final Thoughts:
If you are planning on rooting your phone or even a hard core flashaholic it is essential you use this painless and easy tool to save you when you need it. As noted above you can even revert back to just the kernel, data or whatever that could become corrupt or just plain messed up in the future. I hope this helps you and happy flashing!! - VeNuM

Once again another well written tutorial VeNuM. Going to add this to my list of articles to point people to. Just hope the ones who really need it will actually look here first. Thanks again.

Nice guide VeNuM, will definetly help with the noobs

VeNuM,
This is an awesome Tutorial - thanks for taking the time to write it.

Hi, thanks for a nice simple guide.
After flashing speedmod k3-7 on Criskelo v8 I have lost root.
I would like to restore to before I flashed speedmod to regain root.
Is it possible to restore a nandroid if I don't have full root?
What part should I restore to regain root?
Or do you know a Better way to regain root?
I'm still a noob, so I really appreciate all info I get. Don't want to mess this up.

Venum used CWM as an example, but no, stock recovery wont work. Youll need a custom.

So what if I have expensive taste on paper weights? You got a problem?
Great tutorial, I know how to use it already but this should defiantely encourage more people to use nandroid making you the saviour of a lot of money.
:thumbup:

As always, great tutorial. I've used it to make a backup, but thankfully never had to use it to restore. This does lead me to 2 follow up questions/scenarios:
1. The backup is provided you can get into CWM. What if the phone can't get into CWM and is "hard bricked"? Then I assume in this case you can't do anything, correct? What if you have the backup file on your PC as you suggested. Could you somehow through ODIN restore the backup file without access to CWM (provided the phone is recognized in ODIN)? Or would you have to use ODIN to restore, get it up an running, then install CWM, then use your backup to revert back? I guess it all comes down to if it's recognized or not in ODIN, if it is, then you're not really hard bricked; but if it isn't, your SOL?
2. If the phone can boot up, and let's say is stuck in a boot loop where it doesn't get into the rom, but can get into CWM, but the backup is corrupted. How would you transfer from your PC the backup without being able to "mount" the SD card to transfer it. Obviously with an external SD it's no problem, but what if you only use the internal?
Thankfully, I've never experienced any of the issues above, I'm just curious on the answers. Thanks guys.

Possible Sticky? Great guide, thanks!

Great tut. Just one question... Does the nand backup also create a backup of the internal sdcard ie /sdcard

Wouldn't think that the backup calls to have the storage included. Not that I've seen anyway. That could lead to insufficient space for the backup itself. kernal, modem and ROM are what I believe to be in the backup.
Odd, cause I always pull everything out of storage and pictures to my laptop before doing a nand or anything. Just in case..

pretty useful, thanks a bunch dude :good:

Awesome, thank you for the great explanation. What does it mean when people create a stock nandroid? Are they reverting back to a stock ROM for the backup?

As he said yes. You want a version that will bring you back to stock. So you can start over... Hopefully you will never need to use it...

Using agats kernal recovery it saves backups as .tar I'd there a way to fix? I've never used Odin so .tar are useless to me. I need the .zips

If you wiped the data then it was erased... formatted the partition, same thing. It's gone.
Lesson learned....
Next time, if you make a backup CWM or otherwise, before doing any ROM installs, copy the backup to the external SD Card and/or your computer. That way, if you have to, you can copy the files back to the phone and recover the previous state. I am not really sure that the CWM backup does the modem partition, cause I thought my modem was a different version and restoring did not change the version to what I thought it would be. Don't hold me to the fire on that, like I said, I may be wrong on that....
Good Luck, & Aloha!

Thanks for the lesson. Dont know why CWM didnt save the backup to external in the first place. But there is still about 1gb data missing for some reason.

Mobile Odin/Pimp my rom

Used PmR to download Bravia Engine to try, used mobile odin to flash it, in the process checking ever root and SU options, clearing Dalvik cavhe and wiping data, now my phone is unable to connect to WiFi and data. This does not bode well..

Why you flashed manually with Mobile Odin? The recommended method is to let PmR use the Custom Recovery to flash the MOD. Which recovery do you have installed on your phone? CWM, TWRP?

had CWM, after flashing with odin can't access anything cos of the wipe.
Stupid, stupid me
Stuck at the Samsung logo for quite some time now, what does that mean?
Should i wipe and factory reset or is there an alternative way out?

If you had cwm already then no meaning to use mob odin, anyway if factory reset doesn't work then have to Reflash rom.

You have a nandroid backup, of course? Try the tools on dr.ketan's signature.
As a last resort, you can try Kies to return to official, unrooted, stock Sammy-blessed state. :cyclops:
And start flashing again, afterwards! :angel:

I actually forgot to create a nand backup before messing with the flashing. UGH.
I guess being spoonfed as a previous iOS user has it's drawbacks.
Time to play with everything now that I have such a clean UI

Glad to know that your phone returned to life.:good:
Remember to make nandroid backups regularly.
Good Luck!

I recommend titanium backup or same other compare to nandroid.
Nandroid push you back to original state while you want to test mods and roms, titanium will be much helpful to restore data on cross roms.

was using titanium before, now i can't restore due to my data not being on cloud/sd card.
wouldn't a "snapshot" of my phone now be a better choice for a situation like this?

which app to use for nandriod backups? so far I've seen only CWM/TWRP.

I prefer titanium on ext sd card, bcoz note2 wipes internal sd card too.
Yes cwm/TWRP needs for nandroid.

TWRP seems to be working pretty well, but do i have to extract the folder and back it up on my desktop in case of another full wipe?

TWRP restores everything including desktop but remember it will be same as on day you have created nandroid. Subsequently changes won't have in it.
Sent from my GT-N7100 using xda premium

Oh that's cool! So it really just screenshot the entire phone and restores back to when it was made?
Side note, each backup is almost a GB big, won't it eat up a lot of memory on your phone? As such, which options are best to select when using twrp? (eg efs, data, system)
Sent from my GT-N7105 using Tapatalk 2

Efs is just 20mb, needs when you have messed up imei, it is must in my point of view even if you don't want nandroid backup
data is backup of installed applications
System is ROM, which needs to recover device when you have got something wrong.
