How to update TYT MD380 / 390 UserDB

Edit: I created a very helpful article HERE about how to update a firmware for Tyt 380 / 390. Hi All, I spent hours to try sort out the problem with uploading the UserDB.bin file into my Tyt MD380. However I am quite sure the same procedure will be with Tytera MD390, but surprisingly also with Baofeng DM1702 or RT3S etc etc etc. So, everybody says use a flashing program to upload the UserDB.bin file. And it is true, but nobody, except just one person on website tells the fully story about the UserBD.bin configuration.

So after uploading the file to the radio you must press MENU -> UTILITIES -> MD380 Tools -> DISPLAY -> SHOW CALLS -> USER DB

Only after that the radio started showing people’s callsigns 🙂
