*#0283# earp. loopback working? > speaker loopback working?

no sound from earp + speaker? 70% audio ic
noise from earp and noise from seaker? 80% audio CODEC ic

when you will get 99% solution change the audio ic and the codec ic to!

Be carefull!
-When you soldering the audio CODEC ic to hot > you get camera problem
-When you soldering the aucio ic to hot > you get "phone unknown" ( IMEI: NULL/NULL)

I have same problem.

When i test *#0283# earp. loopback working? it just gives me different options and shows on the menu its set to "packet loopback OFF" I did your other test for speaker was fine and I can record and play back my voice fine.

So whats the issue you think?
