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.

edit: the link is BIN file not zip. So, with stock ROM, nandroid backup is useless then?
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

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

Guys,
I just updated with the CM10 nightly and I am getting a prompt on bootup that my IMEI is not valid. The IMEI is not blank, and isnt something like 0123456789. Is this a big issue? My calling and texting are working fine, as is my mobile data.
Thanks
The same happens to me. I did an efs backup with root manager but is there any risk? Could someone explain please?

Well, in my case, my father's phone lost all efs backups, and nv_data.bin is corrupted (regenerated new one with default generic IMEI).
So, there is nothing to restore from. Reflashing to stock 2.3.6 JW5 firmware didn't help. So you think that I will have to reflash to 2.2.1? How so? I don't understand how older firmware may help restoring correct IMEI...and I don't own JTAG, z3w or SPT boxes...
And for morrons - no, there is no .nv_data.bin, no nv_data.bin.bak, or similiar...only new nv_data.bin(md5) with default, generic IMEI.
Is there any way to restore it? if somebody start to complain that I am thief, I can prove by photos of original phone box, and buying papers I have (my father gave them to me for this purpose).
And no, I don't have to steal anything, I own SGS3, SGS2, SGS, SGT10.1....so stealing another SGS is not an option for me
I just want to restore that phone to it's stock state (and then reflash again with CM10).
Anyone?

you can get a rescue kit from My Android Collections and or a solution from My Android Solutions
just flash a JVU and a PIT , should get you back your IMEI or look at My android solutions for details

Why are you so confident, that JVU will regenerate /efs?
as said before, my father was so genius, that he has wiped /efs partition out. I have restored some data, but without proper IMEI, so now I have generic one. I still do have old JVU package somewhere on my NAS, but I do not understand, how old firmware may help, because I am without any /efs backup anywhere... is that firmware customized so it checks and regenerates /efs if its damaged? If so, why is this feature missing from latest full JW5 firmare? Please understand that I know what I am doing, but right now, I have empty hands...without JTAG, z3w or similiar low-level gadget, it is really hard to restore proper /efs on my own...
But thank you for links, I will take a look on them...
More Clues On Fixing IMEI Issue (solved for me)
In my case I upgraded directly from Froyo to CM10.1 and got then same dreaded 'default' invalid/corrupt IMEI=004999010640000
On inspection of the /efs files present it was clear they had been created by the system in response to not being present.
Following advice in this thread and elsewhere I downgraded back to Froyo (XXJPU) and like magic my correct IMEI re-appeared but as soon as I upgraded up to CM9 it changed back to the invalid default of 004999010640000 again.
To cut a long story short I downgraded back to Froyo (XXJPU) again, flashed a recent CWM recovery and booted into the recovery. I then used ADB to get a (root) shell prompt and discovered that the correct /efs data was being mounted from the device /dev/stl3 and at this point I was able to tar up the contents of /efs and safely make a backup. I then upgraded to CM10.1, restored the correct /efs backup and rebooted.
Happy with correct IMEI now
I am not sure what is going on but I am speculating that the big jump from Froyo to CM10.1 bypasses come critical intermediate ROM build where the correct IMEI data is copied from /dev/stl3. CM10.1 assumes this step has taken place and makes no attempt to get the original IMEI data.

Exactly that. Same goes with going from Gingerbread to Jelly Bean.
That critical intermediate rom... Is CM9
In other words, to safely preserve your IMEI,
Froyo/GB ---> CM9 ----> CM10/10.1/JB

So in my infinite wisdom I deleted com.android.providers.media using titanium backup. I thought I had backed the file up but apparently I didn't. Either that or it didn't actually back the file up. Either way elements of my phone are now totally burned as you would imagine. No gallery, no music in my music player, and no ringtones. So my question is even if I do a factory reset will that help? Yes this was the stock ROM yes I tried installing a stock image on top of the ROM but the installation froze and I had to reboot and restore my nan droid. No I didn't have a nandroid of before I started dicking around. And finally yes I am a complete idiot. Any help would be much appreciated.

Odexed\deodexed....ICS\JB...Stock\Custom....Bell\ATT\Other...not much to go on...either way, go to the Batakang FTP and download which rom you need and you'll always have a backup copy of all the files needed (the bottom two). If your not AT&T, then you can get deodexed versions on my Goo.im page or odexed versions directly from the fastboot.
Sweet thanks man. So would u say that I should safely be able to install over the stock ROM? Or should I wipe then install? Also since these are stock I can install them to ROM slot stock right?

Hey, so I've been doing a lot of research on safe strap and apparently you cannot overwrite the stock ROM slot which would be why I couldn't flash anything to it. So what I did was create a new slot (slot 1) with the stock image. I installed safestrap to that new ROM. My question now would be, If I create a nandroid of that ROM and restore it to the stock slot will that work? Or will it bork due to not having safestrap recovery installed to the system partition anymore and there for stop it from booting along with killing safestrap? Hoping some one can chime in on this one as I'm quite anxious to get back to normal phone use. at least for now all my sounds are back but having a 1 gig system partition is a major bummer.

That's where I'm at. On my stock rom, /system/etc/safestrap was added, logwrapper was modified to execute 2nd-init. AFAIK, that's all that was added. I'm so used to the Defy bootstrap method that I'm having a hard time getting used to SS - Defy BS was clearly laid out on what was executed and when that was done -- I've even looked at the SS source and its scripts and still can figure out what's the first script called by the 2nd-init loader....makes me feel super noob .
Well supposedly hash code said that after every restore and flash to the safe slot (stock) safe strap will reinstall itself on /system so if that's the case restoring any backup to that safe slot should be OK. But if that were the case no one would be able to brick. And I've seen people brick with and lose safestrap, and have to use RSD. Which is the road I don't want to have to go down. Really wish I had a definite answer because it seems like it should work but I don't want to do it unless some one who knows more about this than me confirms it.

Doing a Nandroid backup should take away root as long as you don't install it through TWRP or CWM (they have an option when you go to reboot and it gets in the way)
