tayron Hello,
If you have your own firmware collection, you can manually add devices not yet on the support server to display on the flashing menu list in UFI Android ToolBox .
The default firmware folder storage in Android Toolbox UFI is in c:\ufi\
,
In order not to mix with the UFI program folder, of course you have to move it to another Drive on your computer, which has the largest storage capacity.
You can manually set your firmware storage location via :
settings menu--> Android Data Package Location:
Automatically, upon completion of Installing UFI Software, when first opening the UFI Android ToolBox window, you will be prompted to set the firmware store location of this folder.
And when you first open the support download tab, UFI will smartly create a list of firmware settings from the UFi server support to the storage location on your computer.
But if you want to flash samsung devices, UFI Android ToolBox is not supported atm.
