    820-00850 (A1989) - Booting successfull - Left USB-C ports issue

    Hi, I have here an A1989 where the left USB-C ports are not recogizing any peripherals - charging is working - right side no issues. Could it be that the THB IC is damaged or corroded? (Should I reflow the IC?) Note: The MacBook was water damaged in that area, (U3200 was bad)
