HI … iphone 4s wifi and bluetooth not working … No adress wifi n/d
Waterdamage or dropped ?
I dont know……………
You have to see if c68 have vbat voltage and if voltage is ok then you have to change u1 rf.
C68 is lcd voltage and u1_rf has nothing to do Along with this Problem
just mild reheat wifi chip..post result..
Oh i had wrong schematics opened
Just find if the ic have the correct voltage before you change it.
if you reheat ic it will work for some time maybe for a month maybe for years. (this is not the best solution for me )
