Did I royally screw up replacing my Galaxy S4 display?

[longhorn7101]

I started following a YouTube teardown video in order to replace a broken screen. I didn't finish the job and reassembled. To go with the broken screen, I now have no external sound, no wifi/bluetooth, headphone jack doesn't work, and no LED indicator. Does it sound like anything in particular I (or someone else) can fix, or am I SOL?

No external sound proves you didn't install the USB board and loudspeaker well, no wifi/bluetooth proves you didn't install the signal antenna cable well, no headphone jack proves you didn't connect the headphone jack flex cable connector well, no LED indicator proves you didn't connect the sensor cable well.

Kind of wondering what you expected to happen when you don't finish a job and reassemble??
