I've been trying to recreate a flashable firmware based on the stock TMobile flash dumps and I have complete success.
Heres how to save your current firmware. It will be saved with all apps and settings except for whats on /sdcard.
I recommend reseting to defaults using "Settings->Privacy->Factory data reset" if you want to give these files to someone else to build a flashable rom for you. That will delete all your personal information.
Note: I just backed up a completely setup AT&T Tab, with tons of apps and customizations and restored it to my stock T-Mobile Tab, perfectly! Every app works, home screen is setup perfect, everything!
Effectively this is equivalent to a nandroid backup.
I'll call it "Roto Backup"!
Note you will be prompted for superuser permissions on the Tabs LCD on every dd command.
If you don't have the tar command on your tab, install Busybox Installer from the market.
I just paste the above commands into my command shell window and when im done all the files are siting in my current (backup) directory.
Roto Restore:
First flash the data back:
Now flash the dumps with Heimdall:
Of course you could tar the files right n the Tab and flash via Odin if you really want to:
