I think its fried; boat transformer

I had my Note 4 on a sailboat in Tahiti. Got some great pictures (that I really want to recover).

She was at 3%, I took the fast A/C charger that came with the phone, and plugged it into the 120V boat's transformer... FWIW, I had been doing this all trip with no problems.

The phone makes the charging noise, I lock the phone, I walk away.

Three hours later, I come back, I see the red indicator light on (which I thought was strange, the phone charges in like half an hour usually).... I unplug the cord, light shuts off, and its shown no signs of life since.

I tried a different cord, I tried using my computer, I got a new battery off amazon, I got an external battery charger (thinking maybe the port was compromised).... nothing

I really want those pictures off my phone, money isn't a serious concern... help

Hi!

Did you have your pictures backed up in a Google account or something?

The daughterboard that handles charging may also be compromised, so you should look into replacing it, maybe using this guide.

Thanks for the reply. I have looked into it. Do you know if a compromised daughterboard would cause the phone to still be totally lifeless even if a fully (externally) charged battery is swapped into the phone?

If is would be expected to work with a charged battery inserted, the only path forward I currently know is:

- Buy a working note 4, and swap the motherboard... see if it works

No it wouldn't work even with a new battery, they never do... fuses get blown.

Just make sure you swap the daughterboard, not the main board.

Alex Niculescu 의 2017년 8월 30일

Dude, yes! This is my new path forward.

I'll send the photo I took your way if I ever recover it!

Mike Dale 의 2017년 8월 30일

Alright, have fun and good luck fixing your Note!

Hi Mike,

Just a quick note on photos -

I always set up albums

so that images only exist on SD card.

Maybe you did this as well.

.

Best of luck on the mission Captain,

especially when each image

has $10k$ value.

Thanks Philscbx, I'll be doing that next time (if i can get her working). Have to wait for the parts to arrive :D

I find it odd phone mfg's by default - don't make this a priority for images.

But just by luck, my new LG V20 does have this feature right up front

when creating album,, 'save to phone or SD'.

This has always been a huge step by step process otherwise on every

Phone I have had in the past- IPhone to Samsung.
