Q Mobile E400 Emergency problem solution 100% working

Step 1 =Check if point of I.C (P.A or Signal I.C) is showing 3-5 ohm resistance..If yes then connect it with antenna carefully..
Step 2 =If point is not showing resistance then it is I.C problem..
Already working ic is AP5200
Replace it with same ...
If can not find same AP5200
We can use SKY77569 from E6 (having main IC MT6250DA)
while in E400 Main ic is MT6260MA
