Hello, i read all pages, but didn't find answer.
I'm trying to return my old genuine A2 unit back to service, because my another Icom (genuine Next under warranty) has connection problems.
Mentioned A2 Icom just blink all leds once after connection to OBD.
Is this common failure with known solution?

Flashing LEDs mean nothing. We can only say that the processor does not start, and there can be a lot of reasons.

Thank you for the response.
Just to be clear. All leds blinks once and that is all.
Could you name few reasons, why processor does not start?
How often you needed to rebail or reflow it?
