LG L7 P710 won't boot normally - Optimus 7 General

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
try to download your software version put it on a sdcard then try to enter recovery and then try to install from sd card.

i forgot to mention you must install LG united drivers first. And make sure you follow the step 3. When your phone boots it must be in emergency mode, your screen turns to yellow with a Emergency mode notice.

Sry but I think he should go 3GQCT/Phone modeI: EMERGENCY because DIAG is for when you don't want to delete anything and just update software.

I've tried every other key combo but cannot get into any other mode....i've tried using the lg flash tool with no success, tried uptest with no result, tried the lg mobile support tool and it picks up my phone as the correct phone lge400r with a software version of v20e which used to be a v10b....how can i flash just the correct baseband?....i also tried kdz and when i try and flash the original kdz file it starts but fails with wparam:100 lparam:1002, i'm thinking maybe i have the incorrect firmware kdz....could anyone point me in the right direction with this?....it's driving me nuts

I think that you should use this site LINK. There you have all of the firmwares for L3, and you can choose baseband

yes, i tried that, but the only mode i can enter is download mode.....kdz updater fails, is there a way to flash in download mode?
1. Download THIS, your firmware as .kdz file and LG PC Suite
2. Install msxml.msi, and LG PC Suite
3. Run KDZ_FW_UPD (some antivirus software can recognize it as malicious software, but I have used it, and there is not any problem with this)
4. Select Type: 3GQCT, PhoneMode: DIAG or PhoneMode: Emergency (I don't know what is difference between them, so you have to test it)
5. In KDZ File you are choosing your previously downloaded firmware which is in .kdz format file
6. Boot to Download Mode (vol down + power) in the same moment you have to plug your LG to PC.
7. Wait for drivers installation, if nothing is installing go to the next step.
8. In KDZ_FW_UPD hit Launch Software Update and you have to wait until you see message "===FINISHED==="
That's all.
I used THIS guide.

Optimus L5 (LGE612F) hard brick

My phone is completely dead.
I can´t boot into bootloader/recovery/download modes neither through adb or hardware keys (gets stuck into LG logo).
I have tried doing it with or without battery/microSD/SIM.
It can boot into Cyanogenmod for like 5 seconds just to get to a Demigod Crash Handler (rinse and repeat).
I have a logcat, it is here: http://pastebin.com/wmmTTyqL
This is the kernel-panic (extracted through adb pull): http://pastebin.com/KqeCM9qz
All of this started by flashing through TWRP (@aidasaidas75´s version) Lukosius kernel r16.1
I´m short on money and I can´t buy a new phone.
Is there any hope of revival?
Thanks in advance.
Use the download mode to restore the apropiate kdz file to revive
Step1. Search for all software you will need such as:
A. LG Firmware: firmware
Only select your mobile model phone and country and download the carrier you want to use.
B. Download the LG drivers from here: drivers
C. Download the KDZ installer from here: installer
Step 2: Install the drivers (I did it in a Windows 7 32 bits computer)
Step 3. Unzip and install the KDZ installer (Step 1. Section C: KDZ_FW_UPD.exe)
Step 4. Set your phone in emergency mode:
Reboot your phone: (remove your battery and set it again) while press + and - volume buttons, then connect your USB cable.
Step 5. Select your KDZ(Step 1. Section A) in the installer with the following options:
TYPE: 3GQCT
PHONEMODE: DIAG
Follow the instructions and wait until the software reboot your phone.
Pls help.

Bricked a G2 (D802) pretty unusual

Hello guys,
So I bricked my D802 , how? first it was bricked because of a wrong version of TWRP, untill here no problem, i tried many tutorials on how to go back to stock rom, then i found that it was a Qualcom thing problem, so I found that tutorial about replacing the .img files etc... , pretty easy, i could enter the recovery menu, but it had no rom, i downloaded the stock rom kdz file , started flashing it, then, for some dumb reason the flashing stopped, I ... plug out the usb cable... I didn't notice untill I saw that the program froze, and now the phone is stuck at the LG logo, impossible to do anything, pc doesn't recognize it, can't go to recovery menu, can someone help me please? or at least tell me if I should just throw that phone or keep it if it has a chance of living a bit longer

I had a very similar problem with it getting stuck at the logo after pushing supersu to the phone. I followed Supersport every single step of the way in his video. I think his links are the only valid ones online now, so just download them and reflash your phone. If your G2 is anything like mine, drivers will never appear to be installed correctly and it never restarts, only shuts down.
His method is:
1) Download and install LG drivers on PC
2) Download and install the flash tool and patch it
3) Download and load the .tot and .dll files into the flash tool
4) Enter download mode on G2 by holding volume up while connecting USB
5) Switch G2 Com port to 41 in device manager
6) Once Flash tool shows that all ports are ready, power down G2 and disconnect
7) Hold volume up and reconnect to get back into download mode
8) LG Flash tool starts flashing
9) Complete
Note: If your G2 was screwed up as bad as mine, it'll say failed but all the main system files will load to the device before it restarts and it'll even shut itself off while doing it's installation on first reboot. Mine somehow was still revived from this state with his method.

First of all power of your phone by long pressing power button until screen light goes off completely
Then keep pressing volume + button and connect it to PC via USB cable. [DOWNLOAD MODE]
Now you must be in download mode, simply flash stock firmware.
If you can't enter download mode then you might be in fastboot mode.
here are some threads..find out which one is related to your problem follow instructions carefully.

Thank you my friend for all your answers. In substance;
I can't open my phone. (Staying at LG logo screen.)
I can't do "Hard Reset" with phone buttons. (Because of "boot certification error" screen.)
I can enter "Download Mode" but I can't loading any .KDZ file with Flash Tool. (Stuck at %2)
My computer can't see my phone when I plug that.
Very hard situation. :crying:

Reinstall LG drivers and PDA
then connect phone with PC in download mode.
open device manager and search for 'COM ports' list if you see your device there then you are ready to go.
If your device is not there then search under 'Other devices' and manually install drivers.
If you can boot into download mode and still you can't see your device in your PC then it's not problem with your G2. It's your PC which is causing it all.
Try another PC.
