F900BT mic issues

[Major_Malfunction]

I have a F900BT with mic issues

 

Heres the story

 

Bought one F900BT on Ebay that would lock up on splash screen

Brought it back to life and upgraded it to 3.0 using the directions found here

 

The mic however would not work

No voice command no phone conversations

I would phone people and it would just be dead air

 

Confirmed mic was working cause i use the mic with a F7010BT and it works fine

 

So i assumed the mic jack was bad or maybe a problem with the board.

 

Sold that unit stating that the mic didnt work

 

Now i have bought a second unit with the same issue locking up on startup etc

Also brought it back to life and upgraded to 3.0 per the forums

 

But having same mic issue

Mic doesnt work with voice commands or phone but everything else works perfect.

Once again i confirmed mic is working on F7010BT

 

So i am thinking the chances of getting two units with bad mic jacks has got to be pretty slim

 

Has anyone got any ideas as to what it could be ?

 

Thanks

Well file this under

 

Things that make you go HMMMMMMM

 

 

Reloaded version 2 firmware and reloaded the version 3

and boom the mic works

 

I had done this twice before with no success but for some unknown reason on the third attempt it worked.
