Who knows how to solve the problem with the Fly service code?

Question

Mobile devices

I have a Fly TS100 telephone set, a three-terminal unit, I have to travel a lot for work, and I listen to audio files through headphones, recently the phone suddenly stopped feeling the headphones, turned to a local repair shop, they answered that the phone’s hardware had nothing to do with it, the master checked everything, most likely some software glitch, I was looking for a full factory reset code, I could not find it, does anyone know what could be the matter?

Answer 1

And why did the master not offer you a firmware update? Infinity must support this model.
