No nandroid backup. - Galaxy S III Q&A, Help & Troubleshooting

I think i might be in a bit of a mess here.
i have flashed the SuperNexus ROM and also the Siyah Kernel v1.5 b3, but before doing all this i forgot to take a nandroid backup of my original ROM.
my phone: Samsung Galaxy SIII GT-I9300.
my question is that is there a way i could get a stock Samsung ROM from somewhere incase i need it.
Thanks in advance.

Backing up default stock ROM

Dear all,
Is there any way to back up default ROM from S3? I mean when it's straight from Telco shop?

I'm thinking you would at least have to do a chainfire root, install CWM and backup.
Thank u!

No a custom custom kernel will not remove your ROM, before you flash your chosen kernel read the devs instructions and notes on the brick bug issue. I use the latest siyah have had no problems. Read before flashing there is no rush. All the best

Nope it shouldn't brick your device but Instead of using Odin why not use the safer CWM recovery?

please rephrase your post. It's not clear

He meant stock Samsung kernel.
OP: you can't do this, since CM9 needs kernel compatible with AOSP ROMs.
Then is there any way to remove cm9 rom?

If you want to remove CM9, I am assuming that you wish to replace it with a new ROM. Go through the forum and choose a new ROM and place it in your phone's USB drive or SD card. Then go into ClockWorkMod Recovery mode and Factory Reset/Wipe your device. Then install a new zip and choose the zip file of the ROM you downloaded. If there is any part of this that you do not know how to do, say so and I will give instructions or refer you to one of the many excellent guides that have already been written.
A kernel is essentially only a part of a ROM. So when you flash a new ROM you are flashing a new kernel as well, but when you flash a new kernel you are only changing the kernel section of your ROM, not your entire ROM.

[Q] galaxy can't finish backup

Hello, I have a galaxy s3 rooted with cwm 5.5 something and I'm using revolution Rom by Mike based on JB. I wanted to do backup so I'd be able to recover it at some point in the future, however it says that it can't backup system somehow, shall I update cwm through ODIN and then check?

[Q] Can i brick my phone when by rom-installation all right?

Dear Community, when i make all right by flashing a rom can i brick my Phone?
Thanks for asks.
If you did all flashing process right And if the rom is ok, no, but if you mess up with root files, it can get bricked, i mean with file explorers, after the flashing it.

Don't worry you can make a CWM backup , you can restore your phone that way. If you were to brick your phone and restored via Odin, you can go back to the backup and it will restore everything before the brick :thumbup: . Just install the rom the way it tells you too.
