[Verizon LG V10] osum101:
Hi Guys,

Greetings to all :). So after failing with Googling and trying on my own, i'm here again with another problematic phone :).

(Skip the Description if you want, in short i bought my V10 about 8 months back and i didnt have any issues even with heavy usage/gaming)

I bought the V10 H961N Dua Sim variant used almost 8 months back.During my pre purchase research i became well aware of the infamous "Bootloop of Death" faced by numerous LG V10/V20/G4/G5 phones, But the amazing cost/specs ratio and dual sim support was within my budget and i was willing to take the risk that mine won't be one of the "BAD" ones, and apparently it worked out in my favor.

at the start i was too careful not to even open too many tabs in chrome, but with time i became confident and since after a couple months of buying it i've been using it to have over 35 chrome tabs open at a time, playing some heavy games and compressed movies.

Played PUBG Mobile almost daily for the last month or so, and it just heated up same as my Xperia Z5, with no issues and ho lagging/bootlooping/crashing once.

THE PROBLEM

This Tuesday night, as i was sitting in front of my laptop with the V10 on charge infront of me, downloading several versions of Angry Birds from the playstore (i download a bunch of apps/games at a time and then delete the ones i dont like later) and also it was updating some of the installed apps.

battery (last i checked) was just over 76% or so, and the next time i looked at the phone it was showing the LG Boot Logo (not the animated one, but the static "splash logo" that shows up at the beginning of boot process) . it had turned off and rebooted by itself during charging.

i thought it was nothing, waited for it to complete boot, but when it took longer than normal i pulled out the battery , tried to boot again but again got stuck at the boot logo.

Several retries, same result.

Current State of the Phone

Model : H961N Dual Sim Variant

Firmware : Official Nougat H961N30a_00_0519.kdz Flashed manually via LGUP about 3 months back.

Rooted : No

Bootloader : Locked/Stock State

Problem : Phone gets stuck on LG logo when turned on, waited for upto 15 mins, wont go forward.

There is no apparent overheating i dont feel the phone overheating or anything during boot up process, battery is also normal temp.

JUST ONCE, RANDOMLY, YESTERDAY MORNING IT GOT PAST THE BOOT SCREEN AND WENT UPTO THE LOCK SCREEN, EVERYTHING SEEMED NORMAL AND IT SHOWED THE SCREEN AND ALL THE STATUS ICONS, THEN REBOOTED AFTER LIKE 2 SECONDS :(.

What i've tried so far

Changed Battery, Didnt Work

Can't get into recovery using hardware keys., so cant hard reset it. (the Vol Down key on it sometimes doesnt work so i dont know if its the same thing causing the Vol Down + Power button combination to not work for getting into recovery mode or i am having the same problem as a lot of other users who also can't access the stock recovery on LG V10.

I can get into "Download Mode" by pressing Vol Up and plugging into the USB port of my laptop.

Phone is not detected by LGUP or Device Manager in windows. if i connect it while powered off, it shows the "charging Screen" for a second, reboots to the charging animation screen and then continues on trying to boot by itself. (yes, my v10 cant charge while powered off, it turns on when i connect to wall charger always)

if i connect it to the laptop while in "Download Mode", still not detected.

phone is not visible anywhere in Device Manager, not detected by LGUP, LG FlashTool, Uppercut in either download mode or connected to laptop while powered off (as it continues on to "charge and power on itself")

I used this same laptop to flash the official nougat rom on this phone about 3 months back All Drivers are installed, using the same version of LGUP as before, with uppercut. also tried with LG FlashTool. but this time not detected by windows/LGUP/LG FlashTool. LGUP says no phone connected, the "COM/Devices" list shows up empty.

Also Tried doing it on another laptop with completely clean OS (free from any previous drivers/apps/android related installations), same results.

Tried it on my office desktop with Win 7, no joy :(.

Tried several different USB cables (long ones, short ones, and they are all good quality), didn't help either.

Kindly help me in recovering my V10, as its not even detected by windows in "Download Mode', which i can't understand at all.

Any help will be greatly appreciated. Following is a list of the versions of drivers/apps i have tried so far.
