Phone reboots repeatedly after screen replacement

In answer to the original question here that I didn't see until now, an LCD replacement screen should not be causing boot loops; if it does either the screen is defective or something was broken or done wrong in the process of replacing the screen.

With any aftermarket screen it is not possible to eliminate the genuine parts message no matter how many times you run the Repair Assistant. It's curious that the utility seems to think you do have a genuine Apple screen even though that's not possible since Apple does not make LCD replacements for their OLED iPhones.

Probably too late to help now, and I know you've said you checked the analytics, but just to cover all the bases, check out the kernel panic wiki page to make sure you're looking in the right place for the right files.

If by some miracle you do find a panic log, come on back and post the first page on your question; after that we should be able to diagnose the issue causing the reboots.

One caveat regarding LCD replacement screens that they don't tend to mention is that you're going to find your battery life shortened. OLED screens don't need a backlight since each pixel generates its own light, whereas on an LCD the pixels require a separate light source - i.e., the backlight. So an LCD display will always require more power than an OLED display, meaning your battery won't last as long before needing to be recharged.
