Announcement of Cayin N5ii Firmware v3.9en

 

 

New Functions and System Optimization

 

1. Solved delay after user pressed the play/pause button during music playback.

2. Reset USB Audio Out to the default configuration (noise may occur when playing PCM and DSD files).

 

*The main purpose for v3.9en firmware is to solve the delay after user pressed the play/pause button during music playback. However, if the user unplugs and plugs the earphone after started up the device, the delay (play/pause button and prev/next song buttons during playback) would remain.  Due to hardware and system limitation, v3.9en firmware will reduce the performance and compatibility of USB Audio Output.

 

We advise users to choose this update based on their needs.

6. N5i will automatically go back into recovery operation screen, select “reboot system now” and press power button to reboot into regular operation.

 

Attention:

1. Do not operate the machine during firmware upgrade

2. Please delete/remove the firmware file from the internal storage/TF card after firmware upgrade

3. Please perform a complete Music Scan after firmware upgrade.

4. If you are using TF card to upgrade N5ii firmware, please make sure you ONLY insert the TF card with firmware package into the DAP. Inserting two TF cards into the DAP during firmware upgrade might cause system failure because the system might not be able to identify the firmware package correctly.

5. If you feel the DAP is not performing satisfactory after firmware upgrade, please wipe cache partition (in recovery mode) and restart the system.

6. If the system freezes or cannot resume to regular operation after firmware upgrade, you can turn off the device by holding the Power on/off key for 12 seconds.  The system will shut down in regardless of operation status.  If problem persist, you can perform a Factory Reset (under Setting menu) or Wipe data/factory reset (in recovery mode) to resume the system.

7. Please insert TF card into N5ii before RECOVERY mode. If you insert TF card into N5ii after starting N5ii and RECOVERY mode it may cause system failure because the system might not be able to identify the firmware package correctly.
