CWM not backing up system.img - Nexus 7 Q&A, Help & Troubleshooting

I wanted to flash a custom ROM and decided to do a nandroid backup first. Every time i did one it did not contain the system.img file which means that the stock ROM wasn't backed up. It only backed up recovery and boot. I have the official CWM from clockwordmod.com.
Please help.
BTW. I know that i can use the stock system image from google, but it's much easier to just recover a nandroid backup.

[Q] Clockwork Backup Question

What parts of my phone does a Clockwork backup actually back up?
I am pretty sure it doesn't back up the Modem, correct?
Does it back up both the Kernel and the ROM?
Thanks!
Another question: Is doing a Clockwork backup the same thing as doing a "Nandroid" backup?
if not, what is the difference and how do you do a Nandroid backup?
Thanks (again)!
If im not mistaken a CWM backup and nandroid backup are the same thing, and it only backs up the ROM not ther kernel or the modem

One reply says it does backup the kernel as long as it is a non-voodoo kernel.
This seems right since the backup directory holds all the files that is from the kernel.
I am quite sure that on my phone CWM backup (in recovery mode at least) backs up literally everything.

[Q] Question on Nandroid backups

Now, I haven't cared too much about Nandroid backups since nothing is too important for me to save, and I'm running a different ROM almost every day... But what do Nandroid backups backup ? Just the ROM? ROM and data + Kernel ? And If I do a full wipe and I have a Nandroid backup, do I have to Flash the ROM first, then flash the Nandroid over it? Or can I just full wipe and flash the nandroid?
Nandroid isn't something I use a lot (or at all), so this is kinda odd to me.
A nandroid backup is essentially an image of your entire phone. The entire OS, phonebook, messages, settings...everything.
Awesome, so I can just flash the nandroid right after a full wipe, correct?
Yep, absolutely. Just don't forget that only CWM 3.0.0.6 can flash and restore anything. The other versions are limited to Froyo or Gingerbread, not both.
Yeah I know, I flashed 3.0.0.6 the second i saw it did both ROMs, I haven't had a problem since ^_^ But thanks !
+2 to your Thanks Meter
Glad you got it worked out.

want to come back to original gingerbread

hi everyone
as the title said i just want to remove my cm7 from endless and restore my original gingerbread
i have a backup of my files/system but i don't know how to restore them
i have to flash the correct sbf file before or after restoring the system?
edit: i fell like an idiot, didn't see the topic for questions, can someone merge my question with it?
i think that you can use original SBF again to come back to original rom
i never test that, its a suposition
i think that too but i don't know in wich order
restore gingerbread->flash sbf
or
flash sbf->restore gingerbread
Wipe Data then flash sbf then restore.
But if you did a full nandroid backup with CWM you can just restore it.
i dont' know if it is a full nandroid backup
i have those files: boot.img, cache.img, data.img, nandroid.md5, system.img
if it is the full backup i don't need the sbf right?
by the way i can't use the sbf because i don't have it and i can't download it because megaupload and multiupload are down (i need the italian 2.3.4)
Quick question: is it possible to use the CM kernel with stock UK GB…
i think you can do that, but you must have full cwm backup before, if you wanna restore your data.
or if you wanna band new firmware, you can flash gingerbread rom from firmware.

make a backup with titanium app, then wipe all, flash your new sbf, make root acces and restore backup with titanium again

Files that are inside the backup folder:

question about twrp backup

So I have a twrp backup and I have been playing with different kernels. Now I want to go back to the kernel in my backup. How can I reflash my old kernel without doing a dirty flash? How can I extract it if possible from my backup?

I believe you restore the boot option under TWRP but I'm not 100% on that if someone else could chime in
Yes. boot restore will not affect rom and it is what holds the kernel.
