[Q] How do I backup the stock recovery image?
I am at a loss as to how to backup the stock recovery partition on my Galaxy Tab 2 10.1 (GT-P5113).
If I follow the rooting instructions in this forum, the first step is to overwrite the stock recovery with CWM. That's fine, but I would like to save the factory recovery first, in case I ever need to flash it back.
If I try to use "dd" to copy from the /dev/block device, of course I get a permission denied, since I do not have root (yet).
If I try to use heimdall dump of the NAND chip, I get an empty file.
I have tried various temp root methods, but as I expected, they do not work (ICS, I assume, has fixed all exploits in its kernel).
Is there any way to do this?
