SM-N910F Service manual/schematic request - GSM-Forum

rajkosto · 09-26-2016, 01:42

Note 4 was left in car for 2 weeks, wont boot afterwards, battery is charged and fine.
Opened it up, IC next to removed inductor gets really really hot really fast (when battery is in), discovered short on that inductor, which is why i removed it to facilitate further short tracing (left side is still shorted to ground, need to find cause).
After removal, chip no longer hot, and the pad on the right measures the same as battery voltage (3.8v) for some reason.
Need schematic/layout for further short chasing, I was only able to find free 910S and 910C (service manual with schematics and layout and troubleshooting etc), neither of which have the affected area anything remotely similar to mine, so i need SM-N910F schematics/layout.

So please, i'm just an EE trying to fix his phone, i'm not going to sell or repair anyone else's phones en-masse.
