Under the hood¶

After installing from a full release zip, NX Redux replaces the stock firmware's old Bluetooth stack with newer builds. This is what makes pairing and audio routing reliable.

More detail

The stock TrimUI firmware ships an old Bluetooth stack. When NX Redux is installed from a full release zip, the first boot replaces it with newer builds on the device's system partition (see Getting Started):

Component	Version
BlueZ (`bluetoothd`, `bluetoothctl`, `btmon`, …)	5.78
bluez-alsa (`bluealsa`, ALSA plugins)	4.1.0
SBC codec (`libsbc`)	2.1

The upgrade applies once per device and survives later updates, whether over the air or by copying MinUI.zip.

To check it is present, look for /usr/lib/libsbc.so.1.3.1 on the device (for example with the Files app). The installer uses that file as its "already upgraded" marker.
