Lost galleries, used Dr.Fone for Android and ended up with Odin3

Hi Experts,

Today I lost main DCIM gallery on my Samsung Note 5. I tried to use Dr.Fone application in standard and avanced mode. At the end of the day I didn't manage to retrieve any data. The worst thing is I cannot startup my phone due to "Recovery is not Seandroid Enforcing" error.

I downloaded Singtel Firmware but in Odin3 I get error as follows:

<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> Checking MD5 finished Sucessfully..

Could you please let me know what do I do wrong? By any chance can I recover my phone settings without flashing any data? I still have a hope I will be able to retrieve lost pictures from my gallery.

Thanks and Regards,
KM
