Yes, bad luck. The good news however, is that Fixxo does chip-level repair on logic board (aka motherboard, aka MLB). We are among the very service providers in the city that do L4 motherboard repairs, so you’ve come to the right place.
If we’re successful at the repair, you have to spend only a fraction of the price quoted to you by Apple. Even if the repair attempt fails (sometimes the motherboard is just beyond salvaging), we can replace the MLB for you for much lesser.
