For a mid-range device like the Galaxy On7 (2016), running a modern recovery like 3.6.0-9 provides several technical advantages over the stock recovery:
Open Odin on PC.
Click the AP (or PDA) button and select your twrp-3.6.0-9-on7xelte.tar file. twrp-3.6.0-9-on7xelte.tar
In Odin options, untick “Auto Reboot”.
Click Start.
After flash succeeds (green PASS!), force reboot directly to recovery:
First boot into TWRP → allow modifications (swipe). For a mid-range device like the Galaxy On7
Go to Backup and select all partitions: Boot, System, Data, EFS (important for IMEI), and Modem. Store these on an external SD card. If you ever soft-brick your phone, restoring this backup brings you back to this exact state.
