What do I need to do and get to fix touch ic

Brayden, if you want my honest opinion…this is not something you should follow through on if your goal is to actually repair this phone on a budget. If your goal is to learn, then go for it.

Your question shows that you really do not have the proper tools, consumables and experience in micro-soldering and that you will probably muck things up more than anything else. I don’t say this to be harsh, just to save you time and money. If you really want this phone to work and quickly, let someone else do it.

That said, I don’t think you should be investing money on a water damaged device. I don’t know any techs that actually fix water damaged devices, they can have all kinds of latent issues and are a warranty nightmare.

Now, to be fair, if you want to learn then you will need a hot air gun, paste flux, good tweezers…and tons of practice on dead boards before ever attempting to repair a valuable device on your first try.

Feel free to ask any follow-up questions!
