check your short first, and replace the U2 ic

First of all! The phone turned on, but the battery drained fast, and after a few days killed the battery, (an other shop changed battery), and didnt charge when the battery was empty...
-I changed the u2 ic - still not charge
-I removed the q2 and made the jumer - started charging, but the phone stuck on apple logo...
-I remove the jumper and replace the u2 - still the same, stuck on apple logo! is it possible that because of the q2 jumper the pmic burnt?

Is q2 apart of the charging logic? I just replaced u2 and I am stuck on apple logo, not sure why.
