[Q] Help with Nandroid...what is it?

OK, I think I understand nandroid on a basic level. It backs stuff up. Everything. But I'm confused as to how it works. I have CM 6.1 RC1 on my phone right now. I want to try a Sense based ROM but don't want to lose everything. Especially my apps. If I do a nandroid backup before I install the new ROM will the data be compatible with the new ROM? Will the apps work with all their settings intact? Seems to me a different ROM would have weird little things that are incompatible. Seems to me nandroid is more of a way to revert to your previous ROM in case the new one doesn't work out. Does that sound right?

As I understand it, a nandroid back-up is basically a photo copy of your current rom, apps and settings. If you're using ROM manager go into that and choose the "Back up current ROM" choice and it'll back it up and save it to the SD card. If you install a new ROM you'll do a wipe and everything will be gone and then installed with the new ROM. To get it back to the way it was your have your back-up rom saved on the SD card and you can flash that to get it back to the way it was. Does anyone want to double check me on this since I could be wrong?

That's exactly right. It's a flashable backup of a full ROM. If you want to only backup apps, use titanium backup.

Flashable? So I don't have to install the old ROM first then do the nondroid restore?

A nandroid restore is done through recovery, not the ROM. So you could have a Sense based ROM and nandroid (assuming you have made one and it's on your SD card) to a CM ROM
What you should do is install a ROM, set it up how you like/want it then nandroid right away. You can do that with a few ROMS, test them out, choose your favorite and go with it, always keeping the option to go back to any of them

is it only done through rom manager, or can i get a nandroid backup in cwm recovery?

You can backup in recovery. I never use ROM manager anyway.

[Q] A newbie Q: is CMW a nandroid backup?

Very sorry for newbie Q. I've been using Android for one month now. Though I've rooted, and install CWM, it seems that my knowledge is fragmented. For instance, I installed ROM Manager and ClockWorkMod. Both have backup/restore option. Is Nandrloid backup similar to this? Or CWM is the nandroid backup?
Coz I'm thinking about flashing the baseband and it says i need to do nandroid backup.
thanks

The backup feature in CWM is called a nandroid backup

Yup, you are right! It's the same thing.

Two more questions:
1. I read from a few threads that restore function of CWM may not necessarily working. How do we know when we do the back up that it'll work when we need to restore?
2. The CWM that i downloaded is 3.0.8. I read somewhere that the newest is 3.2 something. How can i upgrade to that? It seems that 3.2 can solve this restore failure.
thanks

If you look in the CWM 3.2.0.0 thread, you'll notice there is a zip file, in that is the recovery image and a batch file that will install it for you.

I did trust CWM with backup of my system before i tried cyanmod ROM... I have three backups on my SD card and CWM restores fine, but system wont boot. So i had to build my phone all new again.
Dont trust CWM

After rebuilding you could have have restored the data backup (not system and boot) and you'd have been OK.

but the need to still rebuild still equates to CWM backups are useless.

That's only true for the original ROM, for custom ROM it's a perfect solution, you just have to flash the ROM again after the restore.

now, i'm confused. So, it's not enough that we restore but we need to flash it again? Like in nvflash or smartflash? Then what is it that we restore?
Also, I just flashed CMW 3.2. Do i need to create a new backup since currently my back up is from CMW 3.0.8?

By flash the ROM again, I meant run the zip file with the custom ROM on from Cwm. You will then have all your data and settings back.

So, if i want to go back to stock rom, i run the zip with stock rom from CWM? thanks.

Do you really have a zip file with stock rom? I don't think so.
Sent from my Optimus 2X using Tapatalk

One could be made though, I suppose.

Sorry I'm confused now
CWM backups don't work? is that why I can't see them when I open CW Rom Manager? I can see them on the SD card but not in the program...
If these backups do not work, is there another way of making backups that work? I don't want to be left with a bricked phone if I try out some ROMS...
I saw a youtube video that showed how to use NVflash, but it was for the G2X and incredibly complicated, battery was taken out, and the phone was plugged in/out of the pc several times, etc... Is theres something similar for the O2X?
Cheers

Yes, it's the link below. Unless I'm mistaken. But not sure if it's compatible with my country.

Backing up and restoring..

Hi guys, just wanna ask, if I fully backup my ROM, is my app being backup too?
Can someone guide me how to backup everything from cm7, including my app, app data, so that I can restore at a later point?
And also, if I'm returning to stock using nvflash, do I need to revert the ext4 to ext3? If so, how!
Thanks
Sent from my Optimus 2X using XDA Premium App

Use recovery to back up.. easiest and safest.. it will create an image of your rom on the SD card..

So if i use cwm to do a backup of my current rom that basically just takes a snap shot of my stock rom? So if anything goes wrong when i am flashing a custom rom I can just restore my previous backup and all will be working again? (as long as i haven't caused any lasting damage)
Many thanks

Including all... Apps, settings etc. CWM saves the entire content of system, data, boot and cache partitions.
You can even make a specific restore in advanced restore menu of CWM you can restore only data for example..(data is where all user apps with their settings are stored)
A good rising app is AppExtractor (see in market) than can use CWM backup files to restore apps, sms, etc... But this time from within the launched system, not from CWM recovery.
Titanium is a must too.

Hmm, so do I complete backup using cwm and also using titanium backup? Or I just need to backup using cwm only?
Or.. how bout' telling me the step to backup my whole cm7, plus guide to restore it back? This is my first time backing up.. :/

I have both: one Nandroid using CWM, to be able to restore the entire system if needded or if I want to try another ROM and come back later, plus a Titanium to have only app backups.
There is no howto to write, they are all already written, and using those two apps is really very simple no need to explain. Just menus to explore. Which steps ? Have you ever looked at CWM menu? it's all written : Backup restore etc... just select.
Try it by yourself it's the best way. You can't harm anything.
Try AppExtractor once you've made your backup you will see its possibilities, can nearly replace Titanium.

Oh ok, thanks!
And.. if I backup cm7 ROM, I have to be at cm7 in order to restore that back up? Or I can just restore the back up with other ROM?
P.s. What about the ext4 thingy? Do I have to go back TO 3 if I going to flash my phone to stock using nvflash?
Thanks a million man!!!

What are you talking about?
Titanium restores APPS... doesn't have anything to do with ROM version...
CWM restores the entire ROM. And for your info, CWM isn't part of any ROM it is a software installed in a different partition called /recovery. When you are in CWM you are not in a ROM you are in ... CWM.
Ext4 and Ext3 are file systems try Wikipedia, too long to explain... If you restore a ROM with CWM 5.0.2 version you don't have to bother about that as CWM reformat partitions according to what is specified in backup files.

Okay! Now I understand.. Haha

Cant restore CWM backup

Yesterday, I tried to change ROM (to check it out) so before this I did a backup in CWM.
What a surprise when CWM didnt restore this backup. I was looking through the internet for solution and I found this:
http://forum.xda-developers.com/showpost.php?p=15431672&postcount=24
I have same problem as in first post of this thrade (when restoring data, the whole process is stopped) but this solution seems to be for HTC Desire. What could I do if I want data back?
Please help me.

r u using same version of CWM to backup and restore?

Yes, it is the same version

Did you chaged you kernel ? because some kernel and roms have different CWM versions.eg: version 4 backup is not copatible with 5cwm

No no, i didnt change anything. The problem is described in that link, it seems that some versions of cwm have problem with restore and have to be fixed than the restore should work. But I dont know how to fix it.

Just simply update CWM to a newer version before restoring the backup.
I pushed the commit long time ago so any "recent" cwm (5.x) will solve the problem.
Hope this helps

Thanks a lot LinoX, but there is only CWM v4.0.1.5 for x8 on XDA.
Is it useful (should I try it?) or do I need newer version? (as you wrote 5.x.x)

marek.ns said:

if it is an unmodified build (from source) then yes (sometimes there're custom modified builds to add functions. Those recoveries can be problematic because they break more than they fix. Recoveries are really important and you should install only "trusted" ones.)
Try with this one and let us know if it suffices (I'm sure 5.x has the fix, I'm not sure if 4.x had it too...but you shouldn't do any damage..at most it will halt again when restoring)

It seems to work but after first restore there were many apps not be restored, so i did another one. It is better now but still there are about 5 apps not restored plus stock Internet browser (dont know if some other system apps too).
I think it is strange that after every restore there is not same result and not what was backuped at all.
Where could be a problem and is it worth to try restore until everything is restored?
It is true that backup was created by cwm3.2(seems ported from x10mini) included in gingerdx rom i use.

The last thing i'd like to ask.

Hi, I have a nandroidbackup made using CWM 5.0.2.7. And I want to restore it. Now I have CyanogenMod7 and I have Clockworkmod 5.0.0.6.
So I copied the nandroidbackup from external_sd to internal_sd, and now when it shows up in my restore menu.
Is there any problem that the backup was made with Clockworkmod 5.0.2.7 and I restore it with Clockworkmod 5.0.2.6 ?

[Q] Finallly rooted my N1 - so what is next for a new ROM?

Well after having my N1 for two years (I bought it on launch day) I finally got up the never to root it using this process.
http://forum.xda-developers.com/showthread.php?t=1319653
Had a few heart stopping moments as the script hung until I realised that while I had download the SDK to get the USB driver I hadn't actually installed the driver for the phone.
Confirmed that it was rooted by downloading Titanium Backup and doing a backup.
For a new ROM (as yet undecided) is a Titanium Backup good enough or should I also do the cyanogenmod clockworkmod recovery?
Should I be able to restore my apps and settings after the new ROM using the Titanium Backup?

You wanna do a Nandroid or Full Image Backup with Clockwork. Titanium is just as you said apps and data. Although, I think CWM has a system bu option. Don't use CWM anymore use Amon_Ra. So not up on steps. The post 3.0 CW's have had issues and are documented.
You can restore apps and data at any time with Titanium, but I think to do system stuff you need to be restoring to same rom.
I highly recommend Nandroids and sdcard backups before doing any new flashing.
Start with CM7 roms the stable ones, then move on. Read OP pages fully and scan threads front to back for info/problems etc

use the pre 3.0 versions

Let's try Amon_RA Recovery
Best recovery by far. Never any issues. Been using this version for months and months. Perfect with flashing, backing up, restoring, and partitioning.

are you experienced with fastboot commands adb etc

The downside with Amon_RA is it doesn't give you the option to wipe the /system partition. I have stuck with a pre-3.0 version of ClockworkMod for this reason. There is a new recovery out there called 4EXT that is based on ClockworkMod, but doesn't have the issue with corrupting partitions. He has also added a TON of new features. This does seem to be the best on out there now. He even just released a touch-based version. The thread is in the development section.
