Your battery is dead... I had the same problem some weeks ago. I had to buy another battery and replace it. Theres a thread where someone explained how to solve through another way, i think changing some cables i dont remember.
But for now my suggestion is to buy another battery and replace it o send it to Sony.

Was your bootloader unlocked before you updated to 4.4.4

With your problems is your battery seem dead , but you can try do :
- Let ZL died then connect the charger
- Start Flash again with xZL power off then press Volume Up try to Flash Manually with Flashtool
- If 2 steps above cant Made your Phone Normally , Just change the Battery NOW .

If your phone is stock try to hard reset with buttons combination.
If you have root and twrp then look on android development for stock rooted rom to flash again from recovery.
For else you must found stock kdz rom to flash it on download mode.

You have custom recovery on your G4 or stock?

alright, this is what i did:
I unlocked bootloader
Following the LG unlock bootloader site guide (http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS)
then i installed TWRP: following this guide: http://forum.xda-developers.com/g4/orig-development/recovery-twrp-2-8-6-0-touch-recovery-t3125859
then installed SuperSU..
after this i logged into the phone again, everything was working, started installing normal apps from the appstore, everything was working and then needed to reboot the phone and it got stuck on the logo, havent been able to
get it back on..
this is what i have done after this: tryed to get into recovery by pressing buttons, but i cant get into the recovery am i hiting the wrong buttons?
then i tryed hard reset with button combinations restart the phone but still nothing happends, still stuck on logo..
when i try to connect the phone to the pc aslong as its stuck on the logo the pc dosnt find the phone, so i cant command it to go to recovery by commaneder.
to answer about the custom rom, i havent installed anything else then TWRP and SuperSU.
factory data reset was the last thing i did yesterday. still gets tuck on the logo.
have any more tips?

I Did this Charge battery fully. 2) Plug charging cable into computer's USB. 3) Pull battery from LG G4 for a few seconds. 4) Plug other end of cable into LG G4 at the same time plug battery in. 5) If the boot loop continues go back to and repeat steps 3 and 4. Or alternate with steps 3 then 6. 6) Hold the power button and volume down button at the same time. Plug in the battery.
After a while this brought up the Optimizing Apps screen and once that completed phone booted successfully. Once booted, promptly enable Airplane mode. When I disable Airplane mode the LG G4 goes back to boot loop. but I took out mem card & Verizon sims card seems to be working now

My lg g4 h818p struck on lg logo and iam not able to recharge the battery ,which is required for connect to lg bridge and upgrade recovery form it please help

Nexus 5X DEAD/Bootloop

My Nexus 5x that was running 8.1 just randomly turned off yesterday and won't boot into android. Sometime later i tried to turn it back on and it worked and it turned off by itself 2 mins later. i somehow manged it to get into fastboot mode and I then unlocked the bootloader and flashed the stock firmware . But that did not help at all , in fact the phone was now completely dead and it only goes into fastboot sometimes while the other times it being stuck in a bootloop . while luckily when it went into fastboot, i have tried installing different boot images like boot4core but it still wont do anything its really weird,sometimes it doesn't respond to any key combination while sometimes it would go normally into fastboot. Need help , i Have no clue!! plzzz

Same Problem here! Running 8.1 and tap Uppdate Chrome and Alexa App, that the Phone freez and Reboot. After reboot he try to load the apps but freez. Now it wont boot to system and recovery say no command. When i now will enter Recovery the Phone reboots.
No open bootloader and no root. Stock 8.1 Rom from Google
Edit: Try to start Phone in Secure Mode (When Google Logo Popps up press Volume -) Say the System is Corrupt and do a Factory Reset. After Reset the Phone stuck on Boot too
Edit Edit: OK think thats the CPU Hardware Bug. Phone dont start anymore...

My daughters phone just started doing the same thing this morning. Haven't gone through any tests yet, but it is constantly restarting. Can't get it to go into recovery through normal means.

Question Red Magic 6s Pro

Is it possible to fix this phone? I have been stuck on the fastboot menu for 3 days now and I have looked all over the internet with zero luck. The phone just vibrates once and then immediately goes into fastboot. Same with charging the phone. As soon as I plug a powered usb cable into it, it just turns on into fastboot mode. Rebooting the system and recovery mode don't work either. I tried to flash roms for the phone onto it with adb but it does nothing. It still says stuck in fastboot. Is there a way to fix it or is the phone now a lost cause?

Nevermind I will be getting the Red magic 7 so it doesn't matter now.

Hey I am on a new account so I ended up forgetting I made this post lol. But It ended up being a lost cause. It actually got worse for me because a week after the post it stopped turning on entirely. I ended up getting the Red Magic 8 pro because I couldn't fix it.
