Need urgent suggestion please - G4 Q&A, Help & Troubleshooting

Hello all,
I have been using H815T rooted and running Seven Rom 6.1. Everything was fine. Suddenly my phone restarted all by itself when it was lying on the bed, charging, and went into bootloop. Since then I couldn't restart it. I even flashed the KDZ (cse flash) but same thing happening. LG logo going and coming...going and coming....
Can anyone suggest me what to do please?

[q] d855 rom flash problem

Hello ppl.
I have the G3 D855, and while i was "playing" with the roms before, i reinstalled blisspop rom but my phone stuck on loading screen.. After this i DLed and flashed CM 12.1 but same again.. 3rd rom i flashed was cloudyg3 rom but again phone is stuck on loading screen..
I am wondering is this because battery is low? because even if i have it plugged in it is not loading....
Can you give me an advice please?
Thanks in advance
if twrp is still working, try flashing a stock rom (and kernel?). if it's not, a last resort could be using LG flash tool to clean wipe. you'll also lose all your data
Well.. i charged it for about 4 hours untill it goes ~30% (Dont know why it took so much time), and then i wiped it and reflashed the blisspop rom.
It worked so i guess the fact that i was trying to flash roms and boot them while it was on low battery was the problem.
Thank you again

Bricked D855

I think i bricked my D855.
I was on Lam Hoang 1.8 rom, but i wanted to restore the original firmware v20h.
I've done the same thing i did many times, i tried to use kdz tools to flash the stock rom.
Everything was working fine when i got stuck at 10% in S/W Updating process.
I unplugged my phone after about 30 minutes, then i tried again, with the same result.
So i tried the TOT method, but the problem is the same, stuck at 10%.
It seems to be stuck on modem installation, as the last line in the log is MODEM.
Does anyone know how to fix this?
Thank you.
Resolved.
It was my pc fault.
I'm sorry.

LG G3 not turning on !

Hi Guys I have a problem. I have a rooted LG G3 D855 with v2.8.6.0 TWRP and Blisspop ROM. Now my problem is that I was running SparTaxx ROM on it since yesterday. Today all of sudden it switched off and then I tried to turn on but it wasn't turning on... After removing battery and trying 2-3 times it turned on and then I went to TWRP and quickly flashed Blisspop ROM so that I can get things working and be on the safe side. Now after flashing it successfully the device isn't booting properly and getting switched off. It is not turning on at all. Only when I charge it it turns on then switches off.
There could be 3 cases which I am thinking but I could be wrong
1) Device is R.I.P
2) Battery needs to be changed
3) The device will either get repaired by some repair centre or maybe it wont work...
What do you think guys?
Any guidance or help is appreciated.
I think that is better for you flash a stock firmware with the LG Flash Tools in case of needs of warranty.
Is only an advice.

LG G3 Stuck in bootloop after Flashing Stock Rom

I flashed my LG G3 Because i felt that the sound was not working anymore and that it can be a software issue which it was a hard ware issue ( loud speaker wasnt connected because of screw) Anyways preformed the stock FW Flash following the guide that highonandroid provided to go completely back to a stock rom. After flashing i restart phone and the boot takes forever until it finally hangs on the tmobile screen. there was a point where i left it over night to see if it will turn on but it still hung for a good 8 hours. Ive done everything i can which can be that i preformed atleast hundreds of hard resets but nothing is working.. there was a point where i did manage to turn it on then i tried updating to lolipop and when it reboots the bootloop is back.. Please help!
I assume you opened the back to fix the speaker issue. Did you make sure all connectors are tight?

Same problem here, but here the device is G3 Liger F490L.

I hope somebody can help me.

I have a LG G3 D855 with the marshmallow KDZ flashed with flash tool everything was good and had no problems. Two weeks ago i rooted my phone and the next day i wanted to install Xposed and after searching for a bit i installed it and got stuck in the bootloop. I managed to recover it by using the .tot method and since then my phone is messed up, like when im using it it restart for no reason at all, or just when it restarts i unlock it and 6/10 times it restarts again. I don't know what's wrong with it and i was hoping someone knows what to do since this is very anoying Thank you
On i've asked for help on Reddit, but maybe someone here knows a solution for it. I really don't know what to do anymore.
Hello,
do you want to backup your app data? Easiest way is flash KDZ via flash tool with CSE flash (format all).
