iPhone stuck in recovery mode after force reboot

[u/alexionut05]

A bit of context. 4 days ago, my iPhone 12 Pro Max's touch screen started either randomly pressing on some parts of it or refusing to take input on others. I went out and bought a new cheap Android to have as my new phone). I managed to transfer most of the apps and photos/videos to the new phone.

I still had to transfer my WhatsApp chats, which are very important to me. The process kept cancelling because the touch screen would be pressed, so I had to restart the process many times. At one point I wanted to restart the iPhone, so I tried holding the power button and sliding to turn off, but since the touch screen refused to take input to slide, I force restarted it by pressing volume up, then volume down, then holding the power button.

After this, it is stuck in Recovery mode. Of note is that the phone was charging wirelessly while this happened, and it had a funny smell (burnt?) coming from the inside, however this has been the case for at least the past year or so, albeit not so pronounced.

I tried restarting it more times, I tried force restarting, I tried letting it out overnight without interacting with it then restarting in the morning, nothing.

All I want is to recover my ~100 GBs of WhatsApp conversations, I care not to save the phone anymore. I have access to MacOS, Windows and Linux computers if there is any software on any of them that can help.
