3 Water damage - are these components fried?
I was given a water damaged iPhone 6s and I took it apart (it has been dry for a long time) and followed the guide to fix water damage, took the logic board out and left it in 91% isopropyl for a night and took the stickers off the back emi shields and found what looks like some corrosion on the connectors, and I can’t find any schematics for the iPhone 6s logic board so I don’t know if it’s missing any components.
my question is are any components on this board obviously damaged or missing and does it look recoverable?
(I also should mention that I don’t care about the contents of the phone so if anybody has an iPhone 6s logic board they don’t need I’ll pay up to like $20 for it)
Edit: high quality image links

the stack of 6 cap on the right side of the second picture looks like it might be blown. try using a soldering brush and clean that cap up. it may need to be replaced. also in the second pic theres alot of corrosion in the top left side of the board picture.

You need proper tools to repair liquid damage not just ipa and a brush. Since there is corrosion in that area there is likely damage under that baseband pmic.

@logixal Thanks for your answer! Just wondering what's the stack of 6 cap mean what exactly is that? Also I got an old toothbrush and cleaned it and used it and alcohol to clean off the board, and put it back in, but the phone won't power on, so I am going to try to take off the EMI shields on the other side so I can see if theres damage under them.
