iPhone 7 Stuck in Boot Loop

Hello there,

I have an iPhone 7 thats stuck in a boot loop after replacing the lightning cable. The phone has had some problems before so I’ve done past repairs such as a screen replacement and battery replacement. At some point the home button stopped working so it was used with assistive touch and it still worked. Eventually it stopped charging, so I replace the lightning port, first time it doesn’t charge so I return it and order a new one and install it, finally it starts charging again but is immediately stuck in a boot loop. First thing I try is replacing the battery with the old original Apple one it used to have, that didn’t work so I ordered a new battery and tried it but it still didn’t fix it. Would the issue be caused by some malfunctioning component such as the no working home button (despite the phone booting fine while it didn’t work before)? Or is the board dead? Could it be the new lightning port that I installed thats causing the problem? Any ideas?

Thanks
