I need help

Hi,

I'm not sure which one is the device you have, NR5103 or NR5103E?

If it is actually NR5103, but you've upgraded to an NR5103E's firmware, please check if it is possible to upgrade V4.19(ABYC.5)C0?

If it is actually NR5103E, but you've upgraded to an NR5103's firmware, please let me know what is your NR5103E firmware before upgrade?

Thank you.

Regards,

Bob
