[Q] cwm back up restore tutorial

did a search didnt find anything...
I hear ppl backup and restore there using cwm what does that do ? why does it actually restore?

When you back up using CWM you are doing what is called a nanadroid back up. When you run the back up it creates a complete image of your phone in its current state so all system and data apps, personal settings widgets on your home screen etc are all backed up. So if you flash a new rom and you don't like it rather than starting from scratch you can just restore your nandroid and your phone will be back to the state it was before you flashed the new rom
I would recomend doing a nadroid back up before you flash anything in recovery, some people might say this is required but in my personal experince it can't hurt.

If you flash something in cwm that you were not supposed to, like a theme not designed for your rom, it can cause the phone not boot. If you did a nandroid you can just restore and everything will be back to how it was before you flashed

it is a really simple thing.. I just did it for the first time and it feels easy and nice to have your whole system backed up on your sd card

[Q] Nandroid Backup Freezes. Help?

Hi all,
I'm having some problems doing a Nandroid Backup in CWM.
I go into Rom Manager and reboot to recovery.
I select Backup/Restore and run a backup before attempting to flash a new rom.
I get all the way to Backing up Data... And it Freezes about halfway through. It happened yesterday and today.
I'm running Stock Rooted 2.2.2.
Can anyone help?

Did you wipe first? I always do before restoring a nandroid and haven't seen any issues.

Nandroid backup & restore...

Just want to make sure if the nandroid backup & restore is really working on Sensation with latest CWM since I have made a bunch of backups and I am heavily messing around with the phone for the past 48 hours lol... Just to be sure this backups are going to actually work in case I screw the phone...

Yes.... Works great.

Do remember that clockwork /nandroid restore will not restore the kernel. If you flashed a rom that's using a custom kernel, you will need to flash the stock kernel before trying to restore your backup or you will get stuck in a boot-loop.

Thank you both! Just wanted to confirm!

Question. What was the total file size of the Backup (stock ROM)?

Yes, I'd love to know this along with how to get a copy of the original kernel....or is the kernel in the .zip files on the regional oem rom thread?

not working for me

You can find the stock kernel in the second post in the Android Revolution HD thread over in the development section.

isnt the boot.img the kernel and init stuff? i was under the assumption it was backed up when you do a nandroid on most devices (like HTC). the RFS file system samsung uses on their devices prevented us from backing up and restoring a boot.img file so we have to always have a kernel in case of the good ol boot loop

so to go back to stock kernel, i install it to the sd card then flash it in recovery right?

Yeap... That's how you flash a kernel, but not needed if what you want to do is restore from a nandroid backup... To restore just select the nandroid backup you want to restore. No need to flash any kernel prior restoring from nandroid.

since when do you have to reflash a stock kernel in order to flash your backup? I have tried every rom out here for the sensation didn't like any of them and reflashed my backup of stock with no issues....

This is not true. Nandroid contains the kernel image.
You would only have to flash a different kernel AFTER you restore, if you don't want to use the one that you backed up.

To the point, nandroid restore works perfect with 4.0.1.5 CWM. I confirm.

Getting mixed signals here guys. Does nandroid backup / restore the kernel?

Yes... Restore everything exactly when you back it up... Kernel and everything exactly.

Nandroid is just the CWM backup? Or am I missing something?

Nandroid backup restore

I was running a ROM versed on ulcb3 and using the entropy DD kernel. I just restored a nandroid backup to an L2 based ROM that was packaged with infusion-GB A2. I wiped prior to restore in cwm.
My settings now tells me I'm using the b3 baseband, and I can't tell what kernel I'm on. does a nandroid backup restore the modern and the kernel? I'm guessing kernel yes, modem no. Can anyone confirm?
Sent from my SAMSUNG-SGH-I997 using XDA App

You have to flash the kernel you were using with the backup. I wipe data, flash the kernel that is supposed to be with my restore then ill do my nandroid restore. You then have to flash the modem that you want. Doing restores on the infuse is a little tricky at first.

On a similar note.... when switching between roms that are both nandroided, full wipe, cache, and dalvic are still necessary? I figured a nandroid restore would rebuild the whole phone to the snapshot that was taken at the time of backup......

I do a full wipe. It only takes 20 seconds extra.

Ya for some odd reason when i attempt to use the nandroid back up & restore future i get bootloops on the samsung screen upon restoring, i don't get it. On my HTC i can do it without any problems. Do i have to flash the appropriate kernel for the ROM when i want to revert to it?

When restoring a nandroid, you should only restore the data in the advanced restore option. Make sure to do wipes prior to flashing a new ROM.

Back up questions

1. If I backup the existing Rom from Rom manager or titanium backup, is it the same thing?
2. If I backup once is it needed to back up every time I change room, or I can use only one backup?
Thanks
Sent from my HTC Sensation Z710e using XDA

They're different. ROM Manager is the Recovery Backup i.e. of your entire internal memory whereas Titanium just does a back up of apps.
Backup your ROM with ROM Manager each time you flash something and when you change ROM use Titanium and ROM Manager.

I use 4 ext recovery to back up it'soooo easy and it works wonderfully! I got in a pinch the other day and it was sooo easy to restore my old rom from 4ext back up! I just go into recovery manage backups and from there you can create a new back up or restore. If your restoring make sure to do full wipe ok. But you might try 4ext. I really love it ! It's so easy to use! Easy is good! You might want to give it a try . I use 4ext touch. Is absolutely wonderful!

Yes 4EXT is a very nice recovery, but when restoring from a NANDroid backup there is really no need to do any wipes. If you watch as $EXT or any other recovery restores from a backup, it does a wipe of each partion before it restores that partion and it also wipes the both delvick cache and cache before restoring them.

Thanks I didn't know that I've been wiping good to know
