LG L7 P710 won't boot normally

Hi all,
i have a problem, got a new Lg L7 P710, and i wanted to jailbreak/root etc. but i think i failed with it.
also i tried with KDZ updater, and installing LG modem and Lg Androidnet usb serial port (com6)/ and installed all those drivers needed. My SD card is still in the phone, but i can't see it in ''my Computer'' when my LG is plugged into mine laptop.. also the rooting part its failing.. btw my yellow screen for emergency is not normal, its kinda with stripes, and i can't see the ''emergency' 'word on the phone when it is yellow, sometimes it goes blue screen with stripes...
i don't think its a hardware problem, but i accidently deleted everything also in SD card, and in the phone self, its just like a Stock peg...and also i lost my warranty in 3 weeks -_-'', i can't do anything, only plugg it in mine laptop, and i hear a noise sometimes, dat it is plugged in, but only in ''Device manager'' I also read some other forums, with bricked or unbricked, or ADB ( also tried with this and CMD) but didnot recognise mine phone... as you can see, my phone is connected to mine laptop ( see pictures)
any solutions/help please? :crying:

[Q] D802 int, no download mode brick

Hi everyone,
i have D802 int. version 6 months old with stock 4.1.2 rom (one with ugly blue status bar icons). Not rooted. I try to flash new 20F kdz file with LG Flash Tool 2014 and was stuck on 27%. Flash tool ask me to try again but i did not have lucky. Now I cant go to download mode anymore. When I turn off phone completely, press vol up and then connect to usb comp. port, windows start to pop up new drives (serval in 5 sec) and ask me to format drive (phone). If i restart phone it show only LG logo and then dim screen. I cant hard reset too. Any help what to do?
PS kdz is ok.

D802T won't boot past the LG Logo

Here's the story in brief:
I connected the phone to LG PC Suite, it offered an upgrade to D80220C. I started the update, and left the phone connected to PC Suite over night to allow PC Suite to download the file.
I wake up in the morning to find the phone stuck on the LG Logo with the LED blinking like it does on start up.
Since then, the phone will not boot past that logo.
I tried the few guides for Stock ROM Flashing, but LG Flash Tool always says the phone isn't connected while in download mode.
Can anybody recommend a way to make the phone work again anyhow?

I cannot Factory Reset the phone, it gets stuck on the LG Logo itself. And I am unable to use the Flash Tool as well in Download Mode as Windows Keeps saying phone is not connected.

D802 Bootloop Issue after root [NEED HELP]

Hey guys.
I'm issuing a serious bootloop problem with my D802. I need help.
How things evolved, listen my story.
1- I was using Bliss ROM 6.4 , after a new update my cellular data connection lost. So I back to stock lollipop.
2- I back to D80230c with using LG G2 Stock Firmware (Go Back to Stock) http://forum.xda-developers.com/showthread.php?t=2432476 method. I got a KDZ file and I flash it.
3- Then I used [TOOLS] One Click ROOT+TWRP Recovery for Lollipop Stock Firmware http://forum.xda-developers.com/lg-g2/development-d802/tools-how-to-install-twrp-bump-d80230a-t3072186 to get root and TWRP.
4- Lastly, script broke on somewhere and my g2 stuck at bootloop.
- When I connect the phone to computer with usb cable, I am getting bootloop. [ LG logo keeps appearing in every 2 or 3 seconds. ] and it keep going.
- When I connect the phone to the charger with usb cable, I am still getting bootloop (lg logo thing) 5 or 6 times then I see Firmware update screen. Lastly, phone get stable and it holds firmware update screen as long as it charged.
-When I disconnected the phone from charger and connect to computer, it begin to restarting and bootloop continues.
Most importantly, my phone does not respond, if its not connected to computer or charger. I mean, it should connect to computer or charger with usb cable to respond hardware key commands. ( download mode, recovery mode, or hardware key control mode ) Btw hardware key control mode is korean language)
I tried LG PC Suite resolve update errors , I tried .tot and .dkz method for flashing rom. ( Device goes to bootloop when transferring data begin from computer.) These methods are failed for me. I did not try fastboot mode.
Maybe someone can help mw, I issuing this kind a problem in three years of android user.
Sorry my English :/
