Usb and dlna

Hi there! How to remove restrictions on the usb port for the number of files 2049 pieces? How to remove restrictions on dlna - only the selected song and its environment are played (about 100 songs, I didn’t count for sure), while not leaving this environment. That is, instead of my 3000 songs, I listen to about 100 tracks. The application does not affect the work - I tried 4stream, wiim. Firmware version 4.6.415145.35

Is it possible to see the manufacturer’s comments? I understand that this is done due to the limitations of the mediatek 7628 chip itself? I would like some alternative firmware without restrictions on the responsibility of an advanced user to check how it works without restrictions.
