do you have also parition dump which contains /opt from k/j series? Or its backup file /usr/data_backup.img?
Yeah /opt base contents is in that image, rest is user/online dependent.
I mounted provided image but /opt is empty. So where is the opt contents ? Backup image also not present.
Code: Select all

Right, forgot to mention data_backup.img exists on J only. No idea where it is on K (->nowhere), mostly generated by TV I assume, and/or factory written.

I accidentally discovered trick how to list content of /opt directory. It is not limited to opt you can list more folder this way. First create empty file in destination folder on your PC. It doesn't matter how it is named. Then use this command sdb pull /opt <file_you_created>. Then you will get list of error that you can not create that file with content of opt directory. My tv is KU6072.

After further investigation of sdb I have found two interesting things. You can set bigger verbosity of sdb by setting environment variable SDB_DEBUG=all
There is another variable but don't know exactly what this does SDB_TRACE_PACKET=true
Second thing is undocumented sdb command
info: sdb launch -p <pkgid> -e <executable> -m <run|debug|da|oprofile> [-P <port>] [-attach <pid>] [-t <gtest,gcov>] [<args...>] which runs /usr/sbin/sdk_launch on TV
and sdb fork-server purpose of this command is not clear to me

Ok. But the dump is from J series. So data_backup.img is missing in dump. Could you upload it?

Hi All,
on K series the iframe still can access the local files with simple code :
Code: Select all
<iframe style="background: #FFFFFF;" src="file:///proc/meminfo" height=1000 width=700>></iframe>
What version of fw and tv model you have? I can not make it run.
