i tried to update via LGMobile Support Tool but it stuck at 4% and i pull out the usb ... and my phone didn't opened anymore since then(black screen)... i think is bricked...i tried to connect in emergency mode without battery and volum key but nothing ... the pc sees " LGE android platform USB serial port (com5)" in device manager, but when i try to update with KDZ_FW_UPD it says that the phone isn't connected...
any ideas would be helpfull... thx
last option will be jtag in an authorized service...
L.E. I've tried with B2CAppSetup and pc recognize my device as p705 with software v20b but i can't do anything ...
I have the same EXACT problem! The 4% thing happened to me too. But in my case I own a LG Optimus L5 (very similar).
So far, no solution. I did, however, found some light in a post in cyanogenmod forums. I can't post the link, but search for "Hard Brick - To Hell And Back - Guide To Recovery".
Using that software we should be able to rewrite the firmware. Please, take a look, we can pull this off if we help each other.
The problem is that the firmware of the LG Optimus L5/L7 does not contains the same filenames requested by the software, so I'm stuck there.
Last resource: using the "riff box jtag", but it's expensive (for me) and I have to buy it abroad, since I'm from Argentina.
Did you managed something else?
dont worry try again install stock firmware on LG support tool, dont worry if it stops on 4% i had this too, maybe after 10 min it will load 5% and then no stops anymore.
sorry for bad english
The problem is that LG Support tool won't recognize my phone anymore it won't even turn on.
hi all,
I have posted my G2 problem in another thread but was hoping more people can see it and help me...
PHONE Stuck at LG Logo after power up.
NO Download Mode,
here goes..
Believed I was conned... and this could be what happened to my LG G2 'D802':
my mobile is actually a D801 phone (motherboard) NOT D802 but loaded with D802 ROM
Phone was flashed (by me) with D802 ROM to remove error "Unfortunately, the process com.android.systemui has stopped" caused by corrupted Build.Prop system file during some editing.
touch screen error after new ROM was flashed (tried many diff roms), likely due to incompatible phone settings.
unable to flash D801 kdz since the phone was configured to 'D802', incorrect model detected while trying to flash.
managed to get a D801 TOT file that can resolved the incompatible model issue
Flash completed, phone rebooted..STUCKED at LG LOGO!
pressed Vol+ and USB cable, cannot enter download mode...stucked..
Factory reset using hardware keys, same problem..
please help ! any suggestion/s would be greatly appreciated!! thank you!!

use flashtool with another *dll
His download mode is not functional.
When in factory reset - connect to pc(does it throw errors or add a new device?)
If yes..then - read this
If no then still read it.

Just plug your cable to usb. Turn off phone and inmediately hold the button up and ull be in download mode.
Or If U have 801 rom try to root your phone and do recovery as 801 phone, after flash 802 rom !

Wait so what can you do? Hard reset? Download mode? Nothing?
Can you plug your phone and check that your phone is not detected in device manager?
All the drivers are installed?

Hi guys, i have a little problem with LG flashtool, i have installed drivers but still flashtoll can't see my phone so i cant flash any soft i'm running Windows 8.1/10/7 but no one can see my phone, anny ideas?
also, sorry for my poor english
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?

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.

This method is USEFUL for your situation & unbricking lg Leon LTE
This method is for ONLY metroPCS
Don't hold me responsible if this method doesn't restore your phone or makes it worse. THERE IS NO WAY TO DOWNGRADE BACK TO ver MS34510B after using this method.
Install
LG United Mobile Driver 3.14.1
LG Flash tool 2014 (build 03/07/2014)
After flash tool installation
1. Remove the battery and put it back in.
2. Hold the Volume Up button (ONLY) while connecting to USB Cable
3. The Volume up button needs to be held until it reaches download mode
4. Open device manager and changed the LGE Mobile USB Serial port to COM 20
5. Open the Flash Tool
6. Select Type: 3GQCT
7. PhoneMode: EMERGENCY
8. KDZ : MS34510D_00.KDZ
9. Click on Normal Flash
10. Click on Clear update registry
11. Country: different country
12. Language: English
13. Click okay and wait for the LG Mobile Support tool to recognize the device. It takes a minute or two but the tool will recognize it. The software starts the extraction and re-boots at %100. You can remove USB cable, your device will boot normally, and the device is no longer stuck in a boot loop.

Hi. Same problem like on video.
Also phone can't connect to PC. When phone charging, indicator & display don't lights up. Only thing, that can turn display & indicator on, is fastboot (without battery hold VOLUME DOWN and connect to PC). But PC show "Unknown device".
That's why I can't flash new firmware. Anybody know what it might to be? And how I can fix it?
