A few weeks ago I upgraded MCU from 8.05 from RDS to 8.06 D7027C7_EN_9_I_N_8_R_V8.06 (TV_BOX_BOSS). It worked for a couple of weeks well. After trying to set steering wheel buttons, the radio stopped. No sound and buttons on the radio do not work. Disconnecting the radio from the power supply did not help. It turned out that MCU stopped working. I wanted to rewrite again but unfortunately there is no such possibility in the MCU update tools. Can I do anything else?
