Samsung Tab A7 T500 Replace Battery

[@kaidaten38]

Did the change yesterday, but now it won't turn on... I've put back the old battery, and same issue... It was working before I disassemble it. Don't understand why... Nothing seems broken...
Any idea please?

can charge?

Computer and Odin detects it too
