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:

try this

does your phone come-up with blank (black but backlit) screen ?
if it does then you will be able to use kdz updater in attached link LG-RDTT_1.0.5.4 (needs included windows enabler for this version)
use THIS GUIDE to flash just skip the hosts file editing steps
and let us know
LG-RDTT_1.0.5.4

[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.

[Q] LG Leon 4G bricked

Hello Guys,
yor are my last hope!
I tried to root my device but there was no working way for it.
So i decided to use this guide (http://forum.xda-developers.com/android/development/root-t-mobile-lg-leon-5-1-1-lollipop-t3194145) to root my phone. I didn't know that this Telekom software is simlocked so i used another guide to unbrick it. Unfortunately it came out that the software i used at this time was the metro pcs version of the stock firmware.
Now i am looking for a working stock firmware cause every german/france software from this pages (http://lg-phone-firmware.com/index.php?id_mod=171) and (http://www.lg-phones.org/category/lg-leon) didn't worked for me.
Every time i tried the 3GCT with Emergency and the cdma with cs_emergency way.
But it always ends in a bootloop with the lg logo and the android symbol then restart and long time LG logo.
I don't understand why Telekom and Metro PCS versions worked but the others don't.
It would be great if you could explain me this.
Greetings
Sven

Hi there! I'm in the same situation. :/ Any help?

I have the same problem too. There's already topic about this, but nobody found solution yet. :/

My god! I have the same BIG problem with LG Leon LTE H340n (C50)! HELP!

Help
Hey guys, I'm a new member so I can't start my own thread so I figured I'd try this out. I bought a LG risio (Leon) off of craigslist and the dude factory reset it when I handed him the cash but now it's asking me for a e-mail or phone number that was previously used with the phone and now I can't get a hold of the guy. Is there any way to get past this situation or am I screwed?
Please don't hate on me for posting this where I did. I just don't have any other options so if someone can help me please do.
