K750i with no sound!

[th3m4trix]

Hi!
I have a big problem with my k750i!
Since some time ago, often my phone become completly mute (can't play boot sound, ringtones, calls, radio or media player).
I can reboot or reflash it but the problem never go out...but magically, after some time, the sounds returns and the phone become normal.
I notice that this problem arise since i flashed for the first time the acoustic settings...what can it be? what can i do?
Thanks!

maybe a problem on buzzer part, loose contact.

uhm i don't think so because i can hear a little rustling instead of the sound when it plays something!

if the problem started after you flashed your acoustics, then a good place to start would be to re-flash the acoustics if you made backups, or to use another acoustic pack. If worse come to worse, reflash the entire firmware...if still no, maybe you shorted out the speaker and you might need to replace it.

take the phone to nearest service center dude if re flashing the main and fs fails try flashing with a different firmware an old one may be!

It is to do with faulty acoustic drivers. Reflash drivers like toshara, hyper or the original k750i sound drivers.

Maybe there is dust near speaker. Try to clean

you damaged the speaker coil contacts, proboably by playing music too loud. time to replace the speaker

go *>*<<*<*> then go to "service tests". then you can test out which part had been broken

Just instal hyper SE NSE acousTic v6 is best for K750 and have all sounds in optimal level
