[Q] Backup Stock ROM - Galaxy S II Q&A, Help & Troubleshooting

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.

Problem restoring from backup using CWM? [Help appreciated :)]

Greetings XDA-World.
Well, Firstly, id like to mention that today is my first day as a registered member of xda. And Yeah, im just 15 so you can call me a noob or inexperienced, i dont mind.
Well Anyway, before i flashed CyanogenMod 7.2 RCO by vo-1, I took two backups of the original stock firmware, one using CWM 4.0.0.9 and the other using CWM 5.0.2.6. However, i decided to go back on stock using the backups but failed, and my Ace is stuck on bootloops. If someone could help me get these backups to work, i would be really grateful.
Any help will be greatly appreciated.
[Admins im sorry ive posted in the wrong place or wrong method ot whatsoever, im a newbie]
Thanks,
UsmanJ

You cannot restore Stock ROM's backups using CWM. If your stock rom was on ext4 filesystem then it could have been possible. But, I think you made a backup of a stock ROM and not a custom ROM based on Stock ROM. Lol, a bit confusing but you cant restore that backup as far as my experience says.

Thanks brother. Yes, i could guess that because most custom rom format the system partition as ext4 because it occupies less place. Isnt it possible that we format the System partition in a way tht is supports the initial backup?
Sorry if im too newb.

Ney. Cuz the original backup was taken on a rfs filesystem. You can try one thing. Flash stock rom via odin, root your ace, install ClockWorkMod 5.0.2.6 and then try restoring that backup. Not really sure if this will help but there's no harm in trying

You can flash any other country's firmware. I live in India and I am using Netherlands' firmware now and I dont have any problem.

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...

[Q] CWM Advanced Restore>Data On New Rom

Hi!
I was wondering, before I do something stupid , if there's any problem on doing an advanced restore, restoring only data, so I could get my apps, contacts, etc on my just flashed ROM Cyanogen Mod 9, for locked bootloader. I have two nandroid backups, one with the stock ROM ICS 6.1.1.B.1.10, and the other with a custom rom, I think called ZXperience.
So, can I do a data restore easily without messing anything?
Thanks!
PS: I'm using Sony Xperia U
Depends on cwm version, if it's 6 then you can't but if below then you can

Thanks for response!
Well, I had 6, so I install the v5... I did na advanced restore from the stock ICS ROM. Now, when turn on, it shows sony logo, then it shows cyanogen mod boot animation, then flashes, get's back to sony logo, and then to cyanogen mod boot animation again and so on.
I can't still boot into CWM Touch Recovery.
How can I restore my settings, contacts, etc?

Ahaha, sorry if I'm being to noob, but I was able to sucessfully install my apps, how do I get my contacts and app data back? I see a lot of contacts and data related files but do I have to manually placed them in the right folder or there's an easier way?
Thanks!
didnt you got app data back while installing apps from it?

I wasn't sure, a little odd, but it's ok. I used Titanium Backup Pro to restore app+data from a nandroid backup. Much easier.
Thank you so much for the help and patience!
Stay good!

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.

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