I received a JM4 looper recently and i wanted to save rec mix as wav to card but it didn't work... so i updated the Firmware 2.09. I tried many times but the update doesn't progress to 100%. Each time that stops around 93% or 15% and that fails... Someone has an idea because That makes me crazy!
Firmware DSP 2.07 / MCU 1.05
