Mt vas5054a which i got recently from ebay has i think HC-05 Bluetooth inside a amd2300 metal shield as Enabled has mentioned.But somehow its taking PDU API firmware upgrades and downgrades like an original one..Its even working with the latest ODIS.

But i am not able to open options screen while using edic configuration where the buzzer settings are.It says device not accessible.I think on a genuine one,you can access all settings.
Apoelistas, please try that settings page and see if you are able to change buzzer settings.

I got a genuine one. I can access the edic configuration and enable buzzer settings. Upgrade, Downgrade

LT1976EFE, LT1976IFE, LT1976HFE do the same work. Any of them is acceptable. IF you have LT1976IFE same as me do not change it.

I have 3 types of memory for vas5054a:
   
Left from ebay . No dimple. Not sure if genuine. Non quality laser
Middle from aliexpress: have 4. Genuine, dimple, laser print.
Right I have 10 from ebay USA. Made in USA with dimple same specs as middle . Genuine, laser print.

Does Anyone know the missing resistor specs in the yellow circle, I think it is a 122 resistor but dont know the size??
