[G3 Q&A, Help & Troubleshooting] Shemploo:
Hello, so I'm the go to guy for helping with phones, I've been on XDA a few years now, always a nexus nerd, so I'm slightly in a foreign territory as I try to help my brother unbrick his LG G3.

Situation:

- Brother claims he had app updates, and he had the TWRP app installed, he was running Turbo ROM - (https://xdaforums.com/lg-g3/development/rom-turbo-rom-layers-t3346477) latest version Turbo-vs985-4.0-OFFICIAL-20160509.zip (I have the ZIP) - and that he allowed the apps to update, and the TWRP app did it's thing. (I'm not clear weather it was just the APP update, or if he tried to update the Recovery partition via app).

- Next he said either after a restart or crash, the phone just refused to boot. It stayed off, totally (seemingly)

- He did note that he had battery issues few months back, that his battery bloated on him, but he replaced it.

- When I went to pick up phone, he had it off/battery out for a few days, I think the battery still had a charge. we did a Vol Down/Power with charger plugged in, battery in, and it turned on the screen, I think we were looking at stock recovery if I recall correctly. Few seconds later it turned off and never came back on.

My Observations:

- when plugging into computer, I see a device "Qualcomm HS-USB QDLoader 9008 (COM4) - no device "visible" under my computer. (screen never on)

- fastboot and adb both show no devices.

- I used LG Smart Boot Diagnostics Tool 1.3.1 (from guide http://www.androidbrick.com/unbrick-recover-your-dead-lg-g3-g2-all-variants/ ) to try and diagnose it, but every time I choose the right model from the drop down (LGVS985_AVRZ_VRZ), and confirm, it seems to connect correctly, and it starts to display results as OK (there are more to scroll down to see), but then it quickly disconnects, not allowing me to see other results.

- guide seems to be aware of the issue ..."In these situations Smart Boot Diagnosis seems can’t reaching the emmc and 9008 port shuts itself down and comes back (you hear it, like usb unplugged and back in).".... - and recommends using another step highlighted by this guide ( https://xdaforums.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091?nocache=1 )

- This is where I get lost, [MENTION=6562044]willcracker[/MENTION] seems to illustrate a need for a tot file, which from what I can gleam is LG's original version of firmware format. And that I need to get the exact version of the TOT that was installed with the ROM?

- I browsed the ROM forum, can't find mentions of a TOT file, but my brother did keep a backup of the Turbo ROM on his internal card, as well as a total TWRP backup of a ROM "2016-06-17--21-31-26_MRA58K" that contains boot/data/system/ .win .win000 .win001 etc. backups, as well as xdabbeb_stock_vs98547a.zip and xdabbeb_vs98535b_bootstack.zip -

SO.... I think I might have all the files Except the TOT to unbrick this thing, but I'm not sure what to do about the TOT part.

Any help is appreciated. Thank you for reading this Wall of text.

PS. He mentioned he was more interested in just grabbing photos from the internal storage, vs fixing the device, but getting the photos and fixing it would be an awesome surprise!
