Firmware update TYT MD-390

Upgrading from TYT MD-380 I consider MD-390 being a considerable upgrade in both ways hardware and firmware, better Tx and Rx audio quality. Overall the radio's price is affordable and the quality can be compared with other DMR handheld equipments on the market (Motorola, Hytera). The radio can be programmed by the software offered by TYT or from the keypad (limited options).
For couple of months I used the original firmware and recently being attracted of using the experimental firmware offered by Mark, VE3PZR. All details how to upgrade can be found here, just follow it step by step and normally shouldn't be any issue. I used the procedure in upgrading 6 handheld radios and everything went fine.
