To increasing my testing speed...

Will try to dump user.img...

At the moment I am back at Tizen 2.3 Combination Firmware BQC2... :o

Edit 1.

First attempts without RDX Tool and USB cable...

Hmmm, will try to write to p14... rootfs... seems 500 MB free

User partition is 1,9 GB... p13

I hope data are not spread over whole partition... :D :o

Edit 2.

First attempt with 256 MB...

sh-3.2# mount -vo remount,rw /
/dev/mmcblk0p14 on / type ext4 (rw)
sh-3.2# dd if=/dev/mmcblk0p13 bs=512 count=500000 of=/userDump.bin

500000+0 records in
500000+0 records out
256000000 bytes (256 MB) copied, 14.874 s, 17.2 MB/s

sdb pull /userDump.bin

Edit 3.

Maybe wrong conclusion... maybe settings stored in other partition... :o

Will check:

system-data -> ../../mmcblk0p12

Edit 4.

In case of Combination Firmware BQC2 it work for me.

I have dumped partition 12...

And if i flash it via netOdin... then my Settings are set by default...
