How do I get the phone working for data recovery?
**Edited for cleanup purposes**
My LG G4 (H810) locked up, died when I pulled the battery and no longer turns on. At this point the phone is over 1 year old and is almost certainly out of warranty (or any "hidden" warranties). Neither AT&T or LG are probably going to help and I am likely limited to OOW repair. I have a 509K* phone, so mine is part of the bad range.
The problem is it will likely cost more to send it to LG for a repair then it will be to find a good IMEI range phone so I'm not going to even bother. However, I have two problems for the price of one dead phone: My data is stuck on a dead phone. What makes it worse is I have photos of a deceased cat I can't get back and giving up on the phone effectively means those are gone for good. To make matters worse, LG won't help with data recovery.
By trying my luck with getting LG to replace the phone, I'm effectively losing irreplaceable data I can never get back. On top of that I have heard that LG refuses to replace dead G4's with a different model that isn’t hot garbage known to fail. No thanks - get me something that WORKS.
Since I am in a situation where some data on the phone is irreplaceable, I don't care about the phone. At this point I just want my data back, even if I may not be able to get the phone repaired or replaced. The data is easily worth more then the phone.
The problem with extracting data from the NAND flash directly is I encrypted my phone :(. The encryption REQUIRES I get the board working for data recovery or I will not be able to recover my data. Since I need to repair the board for data recovery, are they are any known faults with these phones that cause these problems? I JUST need the phone to work well enough so that I can recover my data.
EDIT FOR AT&T LG G4 OWNERS
At least in my case, AT&T switched phones without paying off the balance of a dead phone. On one hand the phone was (nearly) paid off so that may be why. It probably won't be a problem, but I'd be prepared for the worst.
I have checked it months after doing this and it no longer turns on at all, but still charges the battery. YIKES!
