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

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?

Lg g2 ls980 bricked (only white lines on screen )while installing recovery by autorec

While trying to install custom recovery through autorec my LG G2 sold as D802 and infact an LS980 got bricked and showing white pixelated lines and black screen.
- No recovery mode
-No download mode shown on screen
- No fastboot mode shown on screen
-Phone shows up as unspecified android device on windows 10 and connected through Marshall London Bootloader Interface
-Phone switches off and on while pressing power key, rest not known
-Flashtool doesn't recognize any device.
-command prompt in fastboot tool can erase data on the phone, but can't flash any img files
I've searched and read various forms and articles through internet. no one has found any proper solution though some people claims that hex code editing or flashing a partition and a tot file through fastboot mode may solve the issue and tried a few of them. No positive sign till now, I'm r trying out the fastboot method right now, But I'm not sure whether my phone is switching into fastboot mode or not
Can some one please guide me to get the partition file (laf.img) for LS980. ??????????
And if someone can share some serious input on this problem, it'll be really useful for a lot of users includng me.
Or even suggest some methods for trying out.
whenever i got stuck with this sort of errors i used to find my way out using reading tutorials and forums on xda. But this time i cant find a way out.

Same issue
I have the same story with my LG G2 D802 any luck?
I have the same issue... Please give updates on your progress
I have Got The Same Issue.....no COM port so as to flash tot, i cant also flash using flash tools. Somebody Help
Same here, you guys burn your G2?
Looks like I'm a bit late for the party. Well i ended up my lg g2 ls980 (sold as d802) in the same condition. I fixed it by booting into qhsusb_bulk mode by shorting the capacitors and using srktool. Now my phone can boot into download mode!
(Note: this method only works if your phone shows up as qhsusb_bulk and not qdloader or something like that)

Bricked my LG L5-E610 or have I?

Hey ^^
I recently tried to install a custom rom on my LG L5-E610 so I rooted the device, unlocked the bootloader and installed CWM Recovery on it. So far so good.
Btw I was going to use this custom rom: http://forum.xda-developers.com/optimus-l3-l5-l7/development/l5-l7-cyanhacker-v2-0-sbp-t3061734
Beeing in CWM I flashed GApps, SuperSU and the rom of course AS WELL AS some sort of baseband (which I think is something that I was not supposed to do as it's not claimed in the custom rom thread)
And now everytime I try to power up the phone this happens: (video on my dropbox) https://www.dropbox.com/s/eifhw0pk1kwz2fd/LG L5 problem.mp4?dl=0
However sometimes after beeing stuck on that screen (and the screen turns off) i can (after pressing the home button) use the phone normally with the custom rom on it. Although sometimes the touchscreen or the speakers won't work.
But usually it's stuck like shown in the video.
I also can't enter CWM Recovery anymore.
Nothing helps so I hope some kind person on XDA can help me
Thanks in advance,
Schubi_1 ^^

Don't be desperate
You installed the baseband of aidasaidas75. I don't know why he made this new baseband, but several people have passed or are going through this situation you are going through right now. Download this file which contains a tutorial that I did (with videos) and follow in the order. Here is the link to download: http://www.mediafire.com/download/puibfc3chbrw2zs/tutorial.rar

The screen is gray? It should show the LG Logo and a message like "Don't remove the USB cable" or something...
Have u done this procedure? ---> 1st - Remove the battery and insert again | 2nd - Click the Volume Up (or Down, try both and see which one works) button and connect USB cable to PC | 3rd - Open KDZ and flash the stock ROM (or whatever .KDZ file you have for the e610) | 4th - If it shows an error in KDZ like Wparam or Lparam (0) just ignore it and wait till it reaches (100) | 5th - Let the phone reboot... You have to be patient here because it takes a really long time! | 6th - Enjoy your phone

my phone doesn't show any logos
the moment it turns on the screen the screen just stays as shown in the video
whenever i connect the phone to the computer (whilst pressing both volume up+down) and then start the kdz updater the only thing that shows up is:
PHONE WAS NOT FOUND!
i tried most of the things you suggested but nothing works
i think the problem is that i'm missing some sort of driver as my phone doesn't get detected by the computer as a LG L5 but instead as "android" wich my computer thinks to be a Mass Storage Device.

you have to leave the screen like this:
View attachment 3716606
If you get put in this way, just connect to your PC and have them install the Stock ROM.
Now, if you could not leave it, try other key combinations to try to enter download mode.
do not give up!!!

Enable debug mode on a LG Leon LTE with broken screen

Hi guys,
I have the phone of my father in law that (I think) is a LG LTD Leon that have a broken screen which stays black when I turn on the phone.
I would like to be able to get back all the datas, like the messages etc to put them back in his new phone (a Galaxy A5) using Wondershare MobileTrans, the thing is I can't enter the pincode on the LG nor activate the debug mode for MobileTrans to work.
I read here and there (on androidphonesoft and fonepaw for instance) that you can enable the debug mode of a phone with a broken screen using ADB commands but I don't know how, so is there anyone that could help ?
Also will the ADB commands help me enter the pin code ?
Thank you in advance for your help.
Ugo.
