Backing up stock ROM before flashing a new ROM... is this possible? If yes, how should I go about it?
Yes... Possible..
Install CWM-reboot in cwm-choose backup.
It will take backup of current rom(stock if u r using)
This is not a guaranteed procedure to backup the stock ROM for *all* situations. Once you install a new ROM, the stock kernel may also get overwritten.
If you were to go back and restore the Nandroid backup of your stock ROM, it may not work because the kernel may not be the same as before.
So my question still remains open.... How to backup (or extract) the stock ROM from your phone (as a precaution) before you install a new ROM?

What's next? aside from installing ROMS?
If you UN-rooted it, then you're stock.
if you ROOTED it, you can run programs that require root access.
If you are going to explore the custom rom options you will probably want a copy of Rom Manager. This wonderful app will enable you to flash a custom recovery, manage Nandroid backups and flash roms.
In the spirit of prevention being better than a bricked phone... MAKE SURE YOU DO A NANDROID BACKUP BEFORE FLASHING A CUSTOM ROM!! ('Backup Current ROM') from within Rom Manager.
yes for sure the first thing you should do is install ROM manager, let it flash clockwork recovery if necessary, then download a ROM and i highly suggest you try cyanogen 6.1 first. feel that out for a week or so, then go from there.
and do a nand backup first! ROM manager will do the backup for you.
I am having 5 Roms stored thru CWM, and I used to Nandroid restore one every time based in a certain rom property. This is normally an easy process.
The problem is when I am on CM7 or ICS and I want to revert back to restore gingerbread based roms then I have to use Odin for istalling the rom all over again!
whenever I see a blue recovery screen I know there will be a problem.
Is there an easy way for restoring rom without invloving the use of a laptop (Odin)? Sorry if this has been been discussed before, but I have checked thoroughly without luck.

Happy new year.
The AOSP ROMs use a different file system to stock ROMs so you can't just CWM a stock ROM on top. You have to install a stock gingerbread rom with odin/heimdall with repartition then you can restore the CWM backup. (can't remember if you have to install a kernel after installing stock)
Thanks but I was hoping for an easier way. Later on I will backup a base ROM then will try to revert to it from AOSP ROMs and will restore the desired rom from there. I have just read from a similar post that is possible.
Hi,
i have a few questions:
Lets say I use a stock GB ROM with CM Recovery. I backup in recovery and then try the new ICS. I dont like it yet, but make a backup of ICS anyway.
I try a restore from a ICS's recovery (i think it is still CM recovery, only newer version), but it fails every time (bunch of errors).
Then I flash a stock GB ROM again, and then make a restore, and it works.
Please tell me why is that? Is there a incompatibility with different versions of CM Recovery?
Am I doing something wrong?
Is there a thread which explains this (didnt find one)?
Can I switch between GB and ICS Backups?
Thank you to all who will respond
You can't restore a GB backup in CM*. They use different file systems and partitions. This is explained a lit of times on the forums
So only way for going from ICS to GB is to flash stock GB rom first and then restore it?
Indeed, and the reverse if going from GB to ICS
Hello,
I need to know before install Overcome & CWM if it's possible to backup my stock KERNEL. Currently i have 2.6.36.3 kernel.
I think that is better to restore with the original kernel if need to use tha warranty one day ?
So is it possible to backup or download the stock KERNEL.
Thanks a lot for your help.
before you do anything get a nandroid backup and save that original nandroid backup.
Nandroid Backups are a full ROM backup, that means:
Radios
ROMs
Kernels
User Data
Trying to claim a warranty after you violate the terms and services isn't the most honest thing to but if you intent to cheat the warranty system that just hold on to your backup. A nandroid backs up everything
Hi,
Thanks a lot for your reply. For the warranty I am okay with you regarding the honesty.
About the Nandroid ROM backup, i read somewhere that full backup must be done but it backup all except the Kernel !
I am little bit lost :
1/ The KERNEL Backup can be done with Nandroid backup ?
2/ Can we make Nandroid backup with stock ROM & stock Kernel (fresh TAB) ?
3/ The CWM is it a Kernel ?
Thanks a lot.

CWM stands for clockwordmod, its a custom recovery. You need a custom recovery before you can start changing things about your tablet. It is Not a kernel. Think of a car. A kernel is like eh engine, the recovery is like a toolbox. Its more complicated but thats the idea. The stock recovery is too limited, which is why we have custom ones
When you do a nandroid back up it backs up everything. When you do a nandroid back it backs up the kernel as well as the ROM all of your settings and app data. All in one.
If you want a stock nandroid Do it first thing after you have a custom recovery. A nandroid is saved in the clockwordmod folder. Then save that file somewhere safe. Flash drive computer t whatever.
Hope this helps

Here is the Flashable zip for backup your Old recovery and kernel
First, You need root
From your stock recovery, Flash backupkernelrecovery.zip.
Approximately 30 seconds, backup process will make a folder "mybackups" in your SD card,
Reboot as normal, and Open "My Files" and see folder "mybackups"..
You'll find 2 file recovery.img(your stock recovery) and boot.img (stock kernel)
For Restore your recovery.img
download overcome cwm from alterbridge86 thread, unzip the file and replace recovery.img from that files with yours..zip again and flash from recovery, reboot and you got your old stock recovery..
Warning: Only restore Stock recovery after nandroid Restore done..with same firmware
Tested on my P7300 and works..
Hello All
Thanks a lot for your help.

1. Your stock rom, and it's data
2. You can flash another rom. But, if you are going to restore your backups. It will be do nothing, because your phones going back to previous rom, data. Do a normal flash rom, and then you can do a backup, if you want.
