Teac NT505 firmware update v1.22

I try do on HR stream app but not do anything? Have to be computer? Thanks

Glad to hear, OP. If you have any issues with version 1.22 firmware, post back and let everyone know. Based on another thread I have been holding off upgrading to 1.22 (sticking with 1.21) because 1.21 has been working perfectly for me so didn't see reason to change.
Cheers!

Thank you for all big brothers for your valuable input. It is working now... cable was the issue. StarTech USB Type A to Type B micro is the cable I used. Make sure to connect to the USB port in the bottom and it said it in the manual the maintenance port.

So far I have no issues with the V1.22.

You might want to try a different USB to micro USB cable I have had a lot of issues with various devices not liking one cable or another.

I put 1.22 on mine as soon as I received my unit and it worked perfectly.

Can't recall the exact process but the unit was connected to the PC with a USB->micro USB cable to do the update.
