My headphone jack was broken so I opened the phone and replaced it with a new one (https://www.amazon.de/dp/B06XCLKX28...2455538&sr=8-1&keywords=z3+compact+audio+jack). When I put everything together I forgot to connect my screen at first. After turning the phone on I received my Whatsapp messages on Whatsapp Web so I would say it booted this time. As the screen wasn't working I shut the phone down and connected the screen properly. After turning it one again, the screen was working perfectly fine but since then the phone doesn't boot. It comes to the screen with the 4 colorful bouncing dots but after some time it stucks and it turns on again (bootloop). I can normally enter the recovery and mount all the storages.

Facts of my phone:
- D5803 Sony Z3 Compact
- dualrecovery (https://forum.xda-developers.com/z3-compact/development/z3c-xzdualrecovery-qa-t3014208)
- SLIMM custom rom 6.0.1 (https://forum.xda-developers.com/z3-compact/development/rom-slimm-t3359831)

What I already tried:
- looking if all the connections to the motherboard are connected properly
- factory reset and wiping cache and dalvik cache
- installing the custom rom again

Do you have any tips what I could have done wrong or try to do to fix it?
