[AC Question]

G900A phone turns on then black screen with every apps stopped error messages.

So I recently unbricked my AT&T S5 with OC4 Stock Modem and Kernel. Everything was working perfectly fine until I clicked software update. The update downloaded and started to install, but after that it goes into recovery mode and ended up failed to update. The phone then reboots to the at&t logo screen, then to a black screen with error messages such as "Unfortunately, System UI has stopped", "Unfortunately, Media Storage has stopped" and "Unfortunately, setting has stopped".... I pressed the power button to see if I can go to emergency mode, but it will give me another one of those error message "Unfortunately, Emergency recovery manger has stopped" or something like that. What can I do to fix this?
