[mrcio89a]

hello,

some time ago i bought an android radio for my audi a3,

recently i installed the mic the next day somehow the sound stoped working,

i did factory resets and deleted the DSP app by mistake, a new dsp app appeared that is orange, the other was green, the sound still doesn't work,

im trying to find the green app online but no success,

the amplifier chip is ic tda7851l

firmware is 8227l

the radio is this:

Did you try a factory reset?

Yes, it didn't work then with pw 888 i did "erase all content" then boom lost system apps, need Rom , still don't understand what happened, it started when i connected the mic to the radio,

Did you ask the seller?

Did you ask the seller?

Yes but he wants to send me a new circuit board

I guess then there is no other possibility.
The problem is that all the China headunits have some software made by the manufacturer. As long as you do not get the original software from the manufacturer it is impossible to do anything.
