Unbrick after Failed Downgrade Lg g stylo ms631 - Android Q&A, Help & Troubleshooting

Hi Guys
I have an LG G Stylo (ms631) that i bricked trying to downgrade from android 6.0 back to 5.1. Last thing i did was use LG Flash tool on my PC to flash the 5.1 kdz, not sure what i did wrong. The device now will not boot at all. Ive rooted, flashed roms, customized the stock rom, etc many times before without any problems, just my first time downgrading.
**NOTA: When connecting it to my pc, only this appears in the Device Manager "Qualcomm HS-USB QDLoader 9008"
Any solution?

I also tried LGMDP, but it doesn't recognize my phone, since i somehow can't manage to install the drivers correctly since it can't boot..

Help lg g2 d620r hard bricked

Hello all.
I have serious problem with my LG g2 mini d620r.i think I hard bricked it by mistake.
I have try to flash one stock rom about 20 times,with windows 8.1 X64bit also with win7 x64bit but no positive result.
I used LG B2C with LG r&d tool that I read here on XDA about LG g2 flashing method (offline and online).
I want some help here what can I do
the device is shown on PC only as HQUSB QUALLCOM 9008.
no download mode nothing at all.
Same happened to me but with an HTC One S, I tried everything I could find on the net but in the end I had to send it in for repair

Bricked LG LS665 (Tribute 2 Virgin Mobile) on my hands, any way to resurrect it.

I was trying to downgrade my Tribute 2 to stock firmware by following this guide:
"LG Tribute 2 LS665 Unbrick with Stock ROM"
(you can Google it, sorry I can't post links yet)
The LG flash tool "FAILED" at 99%, and now the phone is in a really bad state. I can tell that it powers on, because it shows up in Windows 10 Device Manager as a Qualcomm 9008 Gobi Modem. However, nothing appears on the screen even if I try to boot into recovery mode. So, we can assume that whatever is on the eMMC is completely hosed.
Is there any way to resurrect this phone?
