Hi everyone! A few months ago I tried to sort this out with no luck whatsoever. I just want to backup my tablet before updating using adb. I've managed to connect the device wirelessly with adbwireless (my device refuses to be recognized by computers, the adb usb driver doesn't work) and I'm stuck when it's time to figure out using shell commands where is located the block5 (containing the full backup information). In shell, I input "cat /proc/mtd and all I get is: dev: size erasesize name Under this text it is expected to get a full list of the different blocks and where are they mounted. Nothing happens. Using root explorer, I've checked the content of /dev/block, and there's nothing but two empty folders ("dispd" and "vold"). Of course, if I ignore this and input anyway in shell "dd if=/dev/block/mtdblock5 of=/data/system.img" I get the expected message "cannot open for read: No such file or directory". I've searched "mtdblock" in root explorer with no results.. So... what now???!!! I'm desperate!!!
