Hi my friends, I have an N7100 which is dead, I tried pluggging lab supply and it shows current from 0 to 0.20 amperes while pressing power button then goes back to 0. I suspect it needs boot repair but I can't seem to find a good sdcard image to repair it.
Can anyone help please. I would also need the steps to flash it , I would have to check the current consumption to see it's actually doing the flashing progress right?.
I already followed samsung service flowchart to check U500 and nearby capacitors to see if there's voltage there but I Measure no voltage on those caps, no shorts also. Samsung says to replace U501 which is a transistor if there are no voltages on U500 caps. I also checked U501 transistor and saw there's a signal OTG_EN which comes from eMMC I think. Anyways I was thinking also to reflow U500 but how can I discard U500 needs a reflow or it's an SD Boot repair problem?
So many thanks my friends.
