Answer: OK, maybe remote control is not correct with tv box firmware. (from your picture, it is Japanese remote control, but firmware is for South America) Engineer will make a new firmware to upgrade, try to solve this problem
( ISDB-T7800 firmware is for South America, Remote Control is for Japan, So this firmware upgrade to change ISDB-T7800 South America firmware support Japan Remote control)
Please upgrade like below steps
- Please Copy the upgrade file to USB Stick, it is better no other file.
- Disconnect the power of tv box
- Plug on the USB Stick to TV box USB connector
- Re-connect the power of tv box.
- The tv box will upgrade automatic, please don't power off during upgrading, otherwise, the tv box will lose firmware.
- After upgrade ok, it will restart automatically, then you can auto-search tv program
