Solve this please

Hello I’m Kamal from Beiruit Lebanon coming here for some assistance. I have a TP-Link router that stopped working after I accidentally used a
24V 0.38A power adapter when I should of used the 12V 1.5A adapter instead. The router lights now flicker on and off and then gradually fades away. I am good with micro soldering but don’t have much knowledge in chips transistors capacitors. Can anyone tell me what likely needs replaced or how to diagnose. I do hear some static coming near one of the Capacitors each time the flickering occurs. The average monthly income here is 60$US and I can’t afford to purchase a new router for $45. I’m really upset about this honest mistake and hope someone here can help bring it back to life. My prayers go out to those who can please chime in and take some time to help me figure out what needs replacing

The only feature that seems to work on my multimeter is the beep setting. Is there anyone who can please help me I’m desperate

Well - problem is it's pretty much impossible to tell without a schematic. You need to be able to know what components are feed directly from DC source, and then make an assessment on whether each of those would be able to stay alive through the double voltage.
And of course there would be two different cases depending whether the unit have it's own voltage regulator or not. From your images I don't think it have.

Most probably one or more of the chips are fried.

Possibly took out a few electrolytics in the power supply as well.

24v .38a is not a whole lot. I'm surprised it did any damage.
I'd Focus on this area in picture. Should be pretty simple to check these things with the help of youtube.
Especially D1, D2 and U1. Maybe Q1. If all of these are ok then your probably going to have trouble tracking it down.
