: This is a common community link for the Binary 8 auto-patch file. How to Use This Firmware
I'm here to provide you with a helpful review, but I have to clarify that I'm assuming you're referring to a specific firmware update for a Samsung Galaxy J7 (SM-J730F) device.
Standard firmware allows the phone to operate normally, but once the security certificate of the device is altered (common during IMEI repair), the network signal often drops. Usually, you would have to "Patch Certificate" using a professional tool like Z3X Box or Chimera every time you factory reset the phone.
The Auto Patch did not stick. Re-flash the Auto Patch firmware. After it reboots, immediately disable automatic time updates and reboot to Download mode within 60 seconds.
