In case no Developer Options, open Android Settings (-> System) -> About device (About phone or About Tablet).  Then, tap Build number item 7 times.

On Android 7, after switching ON the Developer options at the top of screen, the USB debugging in Debugging section can be changed.

2. On another Android device(B), download the frep2_android64.zip above and extract it.  Then, choose FRep2Setup64.apk to install it.

If your device does not have app to extract zip
Please get some filer app from Google Play.

After installation of the filer app, you can extract zip file by selecting downloaded zip.

When 'not allowed to install unknown apps' is shown
By default, Android OS does not allow app install from apk file and/or non-Google Play app.

Choose SETTINGS and switch ON ‘Allow from this source’ in Install unknown apps for the filer app.

If it is not enough, allow from ‘Android Settings – Apps – Special Access (in menu) – Install Unknown Apps’,

Or, switch ON ‘Unknown sources’ in Android Settings – Security.

Then, retry choosing FRep2Setup64.apk to install it.

3. Connect them by USB cable as device(B) is host.
In the USB Preferences (see figure below), confirm / set Switch ‘USB controlled by’; for device(A): This device and (B): Connected device. If switching failed with the message Couldn’t switch, retry after connecting cable in reverse.

Side(A): FRep2
Side(B): Setup Tool

Or, if any device (such as USB-microB) does not have ‘USB controlled by’ in the USB Preferences and their sides are reversed, connect the cable/adapter in reverse.

4. On device(A), confirm the proper USB connection mode, generally USB charging this device (Charge this device)‘ or No data transfer. [Sony] [Samsung]
