Changed old battery for Samsung replacement. Tablet no longer working.

[Android Central Question]

I replaced the battery of my Samsung Note Pro 12.2 with an authentic Samsung battery. Tablet was flickering at about 70% so changing the battery seemed to be a solution.
It's was fidgety but managed to change the battery. Now the tablet is dead.
Any suggestions anyone?

You did something wrong inside - left off a connector, broke a wire, broke a component, something. Now see f you can find a shop that's willing to work on a tablet that you've worked on and pay them to find the problem and fix it. (Or poke around more, see if you can find the problem you caused and fix it - without causing another problem.)

This is assuming that you measured the battery and it's actually good. If it's bad out of the box, that's the problem.
