Reconnect Power/Cable!

Hello,
There are 6 boots including 'AltLDR' SPD 7730/31. and also try with SLDR

Hello,,
Can you explain what is 'AltLDR' and 'SLDR' functions and their meaning ?!

Under "CPU Seletion", You can select 3 different types for SC7730..SC7731 - Generic, Android 5.x, Crev/Android 6.x ,
plus, on each of them, you can "tick" (select) "Alternative LDR Mode", means - 6 tries in total.

On some of them, it should boot/connect to software, and you'll be able to do desired operation.

Take a try, one by one ...
