Brand and Models : samsung Sm-t111 ( tab 3 lite )
Case : Dead Phone

Try unpacking it and check it turns out it's full short.
Unload the flux cans scattered on the power ic, cpu, even on the PA IC
Execution:
A. Short Circuit at the bat connector using a hot bucket on the U404
B. Lifting U404 is still short at L408 ( V_BAT_SW line )
C. Remove L408 and shoot with a smoking bucket at C177 ( VBAT_RF line )
D. Just pry C177 and thank God it's on
E. Reinstall L408 and U404
a new case appears again, the charge doesn't increase and the current consumption on the usb doctor is 0ma.
Just replace L408...and Thank God...
