Some advice please...Apple logo stuck on boot? after I re-soldered new

I’ve just discovered that the original flex cable must be damaged.

My first step was solder new speaker onto old flex cable. Thats what was causing the phone to get stuck in boot mode.

Then I unsoldered the new speaker, soldered it onto a new flex cable, plugged it in and bam, phone turned on everything ok. Except of course for the Face ID lol. But at least I found the problem, did even have to replace the camera, works fine. So I’m happy about that.

What i’m going to do next is take of the flood Illuminator off the original flex cable and with a heat gun replace it on the new flex cable. That should solve my face id issue. I hope hahaha.

Man what a learning kerb, the last two days feels like a crash course in everything iphone and components/electronics. And soldering at such a small area and size. But I feel like I’ve gained a world or knowlage how all the components work and what does what that’s all thanks to you guys that helped me out through this. I went into it with zero iphone knowlage or electronics knowlage.

It is my first attempt at iphone repairs never done anything like it.

Really thanks for all your help guys couldn’t of done it without you. This is a great forum to connect like minded individuals. And people like me who have never done it and ask a million questions.
