Member: 2653719 Status: Offline Thanks Meter: 0 | My sm-j530f has been damaged by water, i could switch it on only only once touching the motherboard while connecting the usb cable to the transformer and i tested the phone and backed up some data too... Instead if i only leave the usb plugged in it buzzes,you can see the first screen and then it shutdown repeating the cycle. Now trying again multiple times i can only reach the bootloader which is interesting too. What are those pins visible on the motherboard? Can i backup some data easily even from the bootloader? What is ADB enable file? I suspect the only damaged thing is the circuit to switch the phone on, so i'd like to know more about the components i see on the motherboard. |

Member: 2653719 Status: Offline Thanks Meter: 0 | i don't know how to modify my last post... i found my power ic under the metal cap 110#1 it was quite difficult to unsolder it with my hot air gun..i also ended up scratching a little bit the corner of the tfa9890c and twisting a little bit my motherboard since i used two clamps to hold the board... hope my audio will be ok guys what do you think. Now i need to arrange a little bit those balls...i ended up having half of those spheres on my broken ic and the other half on the pcb |

Member: 16943 Status: Offline Thanks Meter: 35 | hi i have checked first the C7061 voltage and i haven't any voltage there. i have not checked the 1.8v in C7062 because i have 1.8v in lcd connector. the emi filters are good because they have continuity and i have between 0.2 and 0.5 volts in the filters and lcd connector. i haven't schematics, then i can't know where comes the 3v (C7061) from. any help? thanks |
