[Q] PIT/EFS Backup of a brand new P6800

Hello @all
since last weekend I'm also a proud owner of a Galaxy Tab 7.7 Wifi+3G 16GB (P6800). Now I have read a lot of threads about rooting,...
But at the very beginning I want to make a backup of all essential parts. In a first step this will include the partition table and the EFS Filesystem.

PIT Backup

=Q1=> Is it true that I'm able to get a backup of my partition table (PIT file) even without rooting my device?
=Q2=> Are the following steps correct?:
1) Put device in download mode
2) Detect device with heimdall
3) Download PIT with Heimdal
=Q3=> Can something go wrong with this method, or should this be absolutely safe?

EFS Backup

To backup my EFS partition, I thought of the following steps:
- Rooting the device
- Using some tool to backup the EFS partition (like KTool for the SGSII / Galaxy Note)
=Q4=> Is there a tool which can provide such a function for the Galaxy Tab?
=Q5=> Or do I need to do it manually, e.g. via "dd" and terminal emulator?


Best regards,
Chris

Regarding the PIT file,
maybe I did not specify that one clearly: My goal is NOT to store the PIT file on the device. I want to download the PIT file to my computer, so I can use it in an emergency to flash a stock firmware with odin & repartition.

Chris

Hello Manipur,
thank you very much for your answer and the PIT file from Samsung. I will archive it, just for the case that I'm forced to flash my Tab with the Odin repartition option.

Best regards,
Chris
