[Q] Backup Stock ROM

Hi all...is it possible to backup my current rom? If so, how?
Thanks
when you boot into clockworkmod you can do a backup there. i think it makes a backup of everything and then you can restore using the clockworkmod...

Thanks. Sounds easy enough. Will give that a try now
I don't think this belongs in the development section.

[Q] Flash a nandroid Backup through Odin?

Would someone please point me in the right direction? I have installed Task14, installed all my preferred apps, and would now like to create a flashable image of my current setup that I can restore via Odin. I play with all kinds of setups and ROMs, but would like the ability to return to my current setup whenever I please. I know I can make a nandroid backup and restore through cwm, but would like to keep an odin backup 'just in case'. Thanks in advance!

Flashing back cm7 from cm10. Is it safe?

So I've been reading through the forums in search of this answer but I've been unable to find a definite one. I want to try epinters cm10 but if I don't like it, is it safe to flash back neutrinos cm7 using CWM recovery? Will I brick my phone by doing this?
Thanks!

The answer to your question is yes. But the best way to return is by restoring the nandroid backup you will create before trying CM10 (or any other ROM). No brick fears unless you try to flash an sbf (which you should never do).

Thank you so much for the quick response.
Before I flashed cm7, I made a back up of my stock. Same applies if I wanted to flash back to stock using the nandroid backup, correct? Sorry, I just want to clarify completely before doing anything.
Thanks again!

You only have to backup your current rom if you think you might want to go back.
Always backup before installing new roms, or making any major changes, or even when you have your current rom set up perfectly. Using rom manager makes it easier because you can name them whatever you want. You can never have too many backups!

Awesome man. Thanks for all the advice. Downloaded rom manager and renamed all my backups with their proper tags.
Going to give Epinters CM10 a go.

+1 This
For all the lazy kids out there, always create a Nandroid before going to any new ROM.
It's only one extra step, and it beats flashing with a SBF and "hoping" for the best...

Again reported...
Even though you are posting in the wrong section I will answer this for you once.
You can make a nandroid backup. By making a nandroid backup you basically backup your whole system that is currently installed on your phone. The Nandroid backup takes an image of your phone the way it is which can be restored later. I highly recommend you to do this every time you want to install a new ROM. Just in case anything goes wrong you will always be able to restore your nandroid backup and you're having a working phone in no-time again.
Thnxx and sorry for posting in the wrong secrion cuz my question was related to a rom i thought it would match here ..

Might i also add to make a nandroid backup you require a modded recovery for your phone.
The most stable and popular one is surely cwm (clockworkmod).
Though i also suggest philz touch recovery for galaxy s3 only because it can compress much more nandroid backups than cwm, plus it has some other cool features.
Im telling you because from your original post i can tell you probably never used a recovery.
You can find VERY easy and trustworthy guides online to do set up a recovery on your cell easily, so i'll let you search for your self, but if you want the absolute fastest way to get cwm recovery on your phone just install the app called rom manager from the play store. from there it is pretty much straightforward and simple....

Please could you take the time to read General > Sticky Roll-up thread > Understanding the basics before rooting? I have laid out the answer to hopefully, pretty much any "root" question you may have.

Anything that is lost after a factory reset, is also lost if you nandroid over it.
You can make a full nandroid backup with philz recovery.

Question about nandroid backup and kernels

Hey.
One question before I flash a custom kernel on my SGS3. I was planning on making first a nandroid backup with the stock kernel-
If I flash a custom kernel and after a few days I want to revert back to the stock kernel will the nandroid backup do it? Or does it copy everything except the kernel?
Does the nandroid backup backup the kernel also so I can go back to my previous kernel too?
Thanks.
A nandroid backup backups everything except kernel.

So not the kernel?
Weird. I thought it did an image of everything.

U can always flash kernels individually. Just an extra step.
