So basically I replaced the front camera flex cable and when I went to turn it on nothing displayed so I figured it was dead then when i plugged the charger in it just keeps vibrating every 3 secs with no display where did i go wrong?
Disconnect your screen cables. Disconnect your battery, and press power button for 15 seconds to power cycle your phone. Reconnect battery then screen cables, making sure everything is seated properly. Restart and test. If this solves it, don’t forget to reset the date and time and reboot. If not, let us know to further troubleshoot the issue. Let us know what happens. Good luck.
Either screen cables arnt seeded correctly or you have damaged the screen flex cables that’s why its vibrating in charge that indicates a damaged screen
