How to recover (internal data from) completely dead/powerless phone?
My son dunked my Evo 4G LTE under a foot of water. It was still on, so I powered it off by holding the top button down, then dried it out in rice for several days. Plugged it in, powered it on - amazing! Looked great! Had to leave for work, by the time I arrived an hour later the phone was a brick - no power, no reset holding the top button (with or without volume up or down), when connected to a computer via USB it neither registers no demonstrates any sign of power.
My main concern is the first four months of my daughter's life in video and photo stored on the phone's internal storage (android "phone memory"). I know, I should have backed it up, but I have two in diapers so best practice sometimes falls by the wayside. I did not have automatic upload set up via dropbox or google.
The phone is under warranty, sprint offered a refurbished for $35 - so I know I can get a working phone back, but I'll gladly opt to pay for a new phone and rip this one apart to get my data back.
Questions for the pros:
1. Is there any hope of recovering the data by recovering the phone? I'm not much of a hardware hacker so this would be easiest for me.
. 1a. Could it just be the battery is trashed? Is it possible to get/replace just the battery?
. 1b. Since USB doesn't bring power, could it be part of the power "subsystem," something that I could independently replace?
2. Alternatively, does anyone out there know how to get to and read this phone's internal storage?
. 2a. Is it a card or chip that can be removed and accessed outside of a phone?
. 2b. A card or chip that I could remove an put into another Evo 4g LTE, or that I could put into a replacement "motherboard" for the same phone?
. 2c. Can I solder some wires somewhere on the phone to try to access the data from another UI (this would be running in the tall grass for me, but I'll certainly try anything)?
For any solution, links to video or written narrative / instructions would be great, but even tips in the right direction or things that have worked on other phones could be helpful.
Is this a good question?
