Softbricked G4 Beat (LG-H735) - G4 Q&A, Help & Troubleshooting

So I tried to root my sisters LG G4 Beat.
I used https://forum.xda-developers.com/g4/help/how-to-determine-dd-parameters-lg-g4-t3184867 to get system.img, I rooted it and wanted to dd it back.
But I forgot about passing bs=1024 (I calculated other params for that value). I realised that, panicked and unplugged USB cable.
And now our infamous DiskDestroyer transformed it into beautiful brick.
I still can boot it into Download mode, but I never rooted (or even used) an LG before so I can't unbrick it. I found .kdz file on the internet, but I don't know how to use it (every program I tried crashes, tells me that it's unorginal...).
However, Send_Command.exe has stopped working now. I can connect to COM9, but every command does nothing... but entering a blank line reboots Download mode? I don't know why.
Please, help me guys...

I did it! If anyone will run onto slimiar issue, try restoring by LG Bridge. It removed all the data, but it at least works...
btw I litterally can't root this phone. But this is for another thread.

[Q] Bricked Galaxy Nexus

So it all started out rather stupidly. I was attempting to flash a new ROM to my phone and I was deleting everything and accidentally deleted the OS by accident (mis-touched in recovery mode). I panicked and I attempted to push a file through adb but it was halting between 4MB - 8MB on a 200MB file. I knew this wasn't right. I ran cmd in administrator mode and tried again and got the same results.
I then moved to ODIN to attempt to flash the ROM. I ran ODIN in administrative mode. Bootloader was unlocked. I attempted to flash the new ROM but it stopped at about 1/8th of the progress (as shown in the download mode). This led to my phone having communication issues with my PC (displayed the phone with a hazard sign on the cord to the PC). I assumed it was bricked after googling around.
I then tried to use OMAPFlash as suggested by other people with the same issue. I did this, followed instructions perfectly, installed certificates. It got to the point where it was attempting to download a file. After 2 hours of waiting, I stopped it stupidly because it was making no progress.
Now my phone is completely black. I have no OS and I am not even sure if I have any files on it. Screen is black, phone not responding to button pushes and it isn't being recognised by my PC. I have tried unplugging it, removing battery and then plugging it in and inserting the battery again and that has failed.
I don't know what else to do. OMAP isn't picking up the phone anymore even though I have followed the instructions perfectly again. The one sign that my phone is still alive is the beeping noise from windows as I insert it meaning something must be happening. This however is soon followed by "Your device is unrecognised".
Can anyone help me on the situation as the phone is in perfect condition (physically) and I can't really afford a new decent phone at the moment.
Here is all the information you may need:
[Before incident]:
ROM: CM11
Rooted: Yes
Bootloader Unlocked: Yes
Ask for anything else.
[Attempted to change to]
ROM: XenonHD
Ask for anything else.
first off, why odin?
its a nexus you can flash back to stock from fastboot. I would suggest you download the factory images for the phone from here:
https://dl.google.com/dl/android/aosp/takju-jwr66y-factory-5104ab1d.tgz
then extract the images into a folder - remove the battery from the phone, put it back in the phone, power up while holding down vol + and vol - to get into fastboot
hopefully you have android sdk installed and fastboot working. use the flash-all script to flash every partition of the phone back to 4.3 stock.
good luck.
Well first thing, did you select the right zip file for your Gnex when flashing XenonHD. Bcz in my case few days ago i stupidly selected the wrong zip file (ROM for Nexus 5) to flash, but luckily i was saved by the CWM via "Status 7 Error".
But your case is more complicated i would suggest you to use Gnex toolkit with Google Factory Images, i hope that it will come for your rescue . Also try this method http://www.androidrootz.com/2012/08/how-to-restore-galaxy-nexus-i9250-to.html maybe it will do some miracle for you. Best of luck.
Progress
So after sleeping on it and spending some time deeply reflecting on the derp that I had made, I successfully managed to use omap to restore my device to the Phone-Exclamation mark sign as posted by another XDA user who ended up sending his phone back. If you search galaxy nexus brick in google images, you will see what I am talking about (can't post image).
I guess the best way to explain it is: [] -- /_\ -- [ ]
Basically it is a phone connected to a yellow exclamation mark sign and then that is connected to a computer.
Is there a way to force my phone into download mode from here. I can't seem to do anything. Some good news is that ODIN is now picking up my device. It is however crashing whenever I attempt to flash the stock ROM (either "odin3 communicator has stopped working" or "odin3 downloader has stopped working").
Any help fixing this?

Messed up lg g2 with cmd

OKAY SO-
My boyfriend soft bricked his LG G2 LS980 (when attempting to get twrp).
When this happened we thought we found a way to fix it but when we were entering commands in my computers cmb with the phone connected via usb to get it out of fastboot something went wrong and now his phone wont turn on at all.
We automatically assumed that we completely ruined it until I discovered that his phone isn't completely off -the screen lights up a bit- and when I plug the device up it shows up as Local Disk Y: and tells me to format multiple discs.
Is there anyway to fix this at all or should I just give up ?

Can you get into download mode. Completely power down. Hold volume up and power.
If so you could possibly tot back.

What do I do?

my sprint lg g4 randomly cut off last night and it is now stuck on repeating the LG logo. My phone was on the stock rom and unrooted. I cannot take it to the sprint store because they said I have a small crack so the techs can't deal with it so m ony option is to spend another $200 on a new G4. I even factory reset the phone from recovery mode and that did nothing. Is there another way I can fix this?
Try connecting the mobile to the computer use the LG Bridge software and there you will find an option update error recovery.. which will basically download the latest same firmware and flash once again
that was a great idea but i tried to plug my G4 into the computer and it wouldnt be recognized even when i downloaded the drivers
Keep pulling the battery till it gets further. If the screen goes dark leave it alone for several hours. Then go into download mode and see if there is a system.img file on /data/media/0
ls -l /data/media/0
If there is an image file that is 4gb then reflash like you would do if you where following the root guide... BE CAREFUL though cause you will have to change the of= paramater to the name of the file of=/data/media/0/system.img or something like that
i honestly have no idea what u said. i plugged my phone up when the phone was in download mode and nothing happened. how can i check if there's a file on my g4 if i can cut the phone on? i have never rooted this specific device so how would i flash it?

Soft Bricked KF2 won't connect to PC

So long story, mom got an iPad to replace old KF2. I took the KF2 after she hadn't touched it for over a month. I rooted, installed some apps, and then promptly bootlooped it (first time rooter, whoops). Then the very next day, she asks where it is, and I told her I took it. She said fine, just don't mess it up, I still need it. What for, I have no idea. Anyway, she finally decided she needed it back, and she plugged it in to charge and....bootloop. I tried to fix it, but after booting it into recovery, it won't connect to my PC anymore.
TL;DR: Bootlooped KF2 won't connect to PC, need to fix without deleting any data. Also, no fastboot cable on hand.
If you can help me here, you're a lifesaver
Hi there! If you could enter recovery try entering the adb sideload option, and check if your computer detects it. Then adb pull all your files, and follow the restore instrucciones, get back to stock and put your files back. Otherwise you'll need a fastboot cable, it saves lives. Reflash updated recovery and that should allow you yo acceso your files.

LG G3 F400L Softbrick. Download mode available.

Hello everyone reading! I've tried many guides here, but none seems to work for me somehow, thats why im writing this post.
Whats my problem?
- I've been having this problem for a year or so now, like most softbricks im stuck on a bootloop while launching the phone, with red and blue led light flashing.
The message displayed in the top left corner of the screen says:
boot certification verify
Secure booting Error!
Cause: boot certification verify
How i have bricked my phone?
- I remember i have tried to unroot my phone after having cm installed, can't remeber the version though. Then the phone just got stuck in the bootloop and wont launch along with recovery.
What have i tried?
- I have tried flashing the phone to stock via lg flash tool (tot and dll) and Lg Flash tool 2014 (kdz) no luck unfortunately.
- While flashing stock F400L rom through tot files im having sometimes Milkyway connection failed error when im launching the program, but i don't think that's the case.
I'm doing everything in right order, drivers and programs installed, going into download mode, changing ports to COM41 or COM1 (neither works), launching lg flash tool 2014,
choosing suitable for F400L stock dll and tot then launching the process, unplugging the phone and after 5 seconds plugging it again.
Nothing happens, im stuck at ready.
- Tying to flash through kdz file seem not to work either, got errors after l start the flash process.
Phone plugged, in download mode, yet i get the message of program not being albe to access it, like it would have problems with connection to the computer.
Im following the instructions that program gives me though it does not help at all. It stops after reaching 4% and asks to connect the phone back after checking connection with the device.
Thanks for any help provided!
