Unable to dump firmware on Sitronix device
July 17, 2014 12:05PM
I just picked up a little digital frame today hoping it could be hacked. Got it home and was delighted to see

Bus 005 Device 009: ID 1403:0001 Sitronix Digital Photo Frame

I then found this thread about hacking the firmware http://forum.doozan.com/read.php?9,2435

I found the DP152 from here http://forum.doozan.com/read.php?9,2435,2503#msg-2503

My dmesg output is

[174986.344749] sd 15:0:0:0: Attached scsi generic sg3 type 0

Then trying hackfw on this device fails at I presume dumping the actual firmware

[parker@localhost st2205tool]$ sudo ./hackfw.sh /dev/sdc
Interactive script to hack the firmware of your keychain photo
player.
Expected response 8 on cmd 1, got 0x5a!
Sorry, there doesn't seem to be a device using the ST2205U chipset
at /dev/sdc.

Trying phack manually as mentioned in the newhack.txt prints the same result

[parker@localhost st2205tool]$ sudo ./phack -df fwimage.bin /dev/sdc
Expected response 8 on cmd 1, got 0x5a!

I am all out of ideas. The only thing I can think of is I also have the /dev/sdd, which I don't see in other people's dmesg output. Maybe my device just isn't compatible?

EDIT: I didn't even notice a model number at first. It it helps this is a DPCI 056 13-0212.
