i have a 6s here that had a small amount of liquid damage, it originally fried U3200 causing the camera and flash to not work, I have managed to bypass using a jumper wire from c3211 to fl3202, and the camera now works again. the other issue I noticed is it wont charge a battery, it will be prompted to boot when charger is plugged in, and even pop up saying “cable not suported” even though they’re official apple cables, but it wont have the charge icon in the corner, and battery % falls, tristar and tigris both look immaculate with no corrosion around them, I’m thinking of replacing tristar next, but wanted a second opinion on this one before i start replacing IC’s Many thanks!

Have you tried another charging port? I would try that before going for Tristar or Tigris. After testing another charging port and still not working go for replacing Tristar first as that controls the USB communication between the board to the charging cable. I would wait for other answers first as there are people here more experienced than me and know what to measure for first before replacing Tristar / Tigris.
