SM-T520 galaxy tab android doesn't work properly, dead android on recovery screen

[francisco fonseca1]

it all started when i wanted to update the firmware on my tablet and then i don't know what happened.
Android boots but then all the apps stop working. Tried to do a factory reset but the button just gets dark and do nothing.
Tried installing another firmware but the same problem happens.
I don't know if i am doing something wrong or what.
