Then try launch software with type 3GQCT and phone mode CS emergency. Next, connect phone via cable usb without battery. Maybe reinstall kdz and drivers.

If you currently have a Jelly Bean then install Jelly Bean.
Uninstall KDZ Flash Tool + drivers and install again.
1.Install drivers.
2.Install KDZ Flash Tool.
3.Turn off your phone. Connect phone via cable USB and pressing volume + and power (without battery). On screen shows emergency mode with yellow background.
4.Open KDZ and:
a) 3GQCT + EMERGENCY
b) 3GQCT + CS EMERGENCY
Disaster recovery software for LGMobile Support Tool rather not work. But you can check it.
If you have P705 then install for P705:

[Q] l3 flashed incorrect baseband help

Hi guys, can anyone help me with this, I recently acquired a lg e400 and rooted it, was going to flash cyanogenmod for it but i messed up and flashed a different baseband for a different model phone first(i know it was stupid, now i have a semi-hard brick and the only mode i can get into is a black screen, computer sees the phone as lge androidnet usb, i enter this by holding the vol down and power as i plug into the computer. 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.

Mode download doesn't work

Hello,
I want upgrade my LG G2 with a new rom 5.xX
This phone have only the operator update. No custom, no trwp, nothing...
I installed drivers and when i want access to download mode. I can't. I use the good proccess with vol up then plug usb cable always with vol up presses.
follow this procces after a little moment my phone show me battery logo charging.
So i can't access to download mode.
I would use this process
t was NOT bricked. I finally tried playing around with the LG Mobile Support Tool (B2CAppSetup.exe). Of course it detected that my phone already had the latest firmware from T-Mobile, but then I clicked Options>Upgrade Recovery.
It downloaded for a while then I noticed it had put my phone into download mode (it said "Rooted" in red letters at the bottom). Then it flashed the same firmware over and I immediately tested, it entered download mode right away. But I didn't end up needing that as Stumproot was able to brute force it now after the recovery flash.
Anyway, I couldn't find an answer anywhere else. Most results also have a bricked phone, but that wasn't my issue. This solved my problem and maybe it could work for others.
but it's impossible for me to install B2appsetup on my pc the installation begin then stop after 5s then nothing.
I have Win 10.
Do you have a solution for me , please??

[GUIDE] [d855] How To Install Lineage OS - A Compilation (Downgrade/Root/TWRP/GApps)

*EVERY ACTION YOU PERFORM FOLLOWING THIS GUIDE IS AT YOUR OWN RISK*
That to be said, let's start: i am currently running the latest official nightly build on my d855 and it took me a while to get there. I couldn't find any (real) step-by-step-guide, where i would not have to google any errors or anything else.
Everything you find here is NOT my own knowledge, it is just compilation of sources, that i found on the internet.
Note:
Android 6.0: if you are on 6.0 and you always updated so you're on the latest security-patch-level the one-click-root-method won't work. I recommend downgrading your phone, which will be explained in the following.
Android 5.0: if you're on 5.0 you need to upgrade to 6.0 anyways, bc you need a different baseband-version to install LineageOS. This will also be explained in the following.
1. Make a backup of your phone
this is recommended, although i didn't do this, this is why i am not gonna explain it one here. I just saved my pics and contacts and did a factory reset, restarted my phone, did all the "first time turned on stuff" and connected to my wifi.
Note: Make sure your phone is charged to 60% at least
2. Download the following
a. Download LG G3 Drivers 4.0.4 and install them (i believe there are more recent ones, but this worked for me)
b. Download LG UP
- Download: LG UP Ver. 1.14: LGUP_Install_Ver_1_14_3.msi and LGUP_8974_DLL_Ver_0_5.MSI
- Make sure to install the DLL first and then the other .msi
SOURCE: Thanks to hyelton
c. Download the proper KDZ for you phone.
Note: I got this infos from a german site.
This is the 30C KDZ for the 32gb AND 16gb version: Download here
SOURCE: Thanks to mr bo
3. Downgrade/Upgrade your android-version
1. Turn off your phone.
2. Run LG UP (the tool you just installed) and press okay when you see the error message, that no phone is connected.
3. Press "Volume Up" on your phone and HOLD it, connect your phone to you computer via USB 2.0 PORT! This is important, bc connecting via 3.0 won't let LG UP recognize your phone.
4. Your phone is now in download-mode and LG UP should have recognized your phone.
5. Press SELECT, click on UPGRADE, then click on FILE PATH, choose you prefered .KDZ.
6. i recommend refurbishing your phone (This will wipe your entire system and make a clean install).
CLOSE LG UP and start it back up. The .KDZ should still be there. Now select REFURBISH and click on START. Wait until 100% completed and you phone has booted up completely.
Source and further information: Hail hyelton!
Also here is a youtube video: Thanks to kiaTech
4. Root your phone
1. Download the latest kingroot.apk from here.
2. Connect your phone (turned on, after all the "first time turned on stuff") and move the .apk to your Download-folder.
3. Open the (stock) filemanager on your phone and navigate to Downloads.
4. Install the kingroot.apk (enable third party .apk, when asked)
5. Open the app and root your phone (it's simple, believe me).
6. Your phone is now rooted (leave it turned on, DON'T restart)
5. Install TWRP and update to the latest version
1. Download this pack and unzip it.
2. Move the AutoRecMMD855.apk to your phone and install it just like kingroot.apk before.
3. Open the app and follow the instructions.
4. You now got TWRP on your phone.
SOURCE for #4 and #5 till here: Thanks to tute123456
5. Boot into recovery mode (either with the app itself i think or manually. If you have to do it manually. Turn of your phone. Press POWER and VOLUME DOWN at the same time until the screen shows soemthing. Release and immideatly press again. Your phne will ask you if you want to FACTORY RESET. Press YES and YES. If everything is working properly, TWRP should start up).
6. Connect your phone and download the latest TWRP.img you. In example here's the european one Latest LG G3 TWRP EUROPE
7. I assume you never disconnected your phone since moving kingroot.apk to it. So now you just move the TWRP.img to your Download folder.
8. Choose INSTALL on your phone and search for the TWRP.img. Select RECOVERY and flash it.
9. Choose REBOOT and then RECOVERY.
10. Your phone will boot into TWRP again. It should be updated to the latest version 3.0.2-0.
SOURCE: Thanks to everyone who contributed
6. Flash LineageOS and install GApps
1. Download the latest version of LineageOS (nightly) from here
Optional: make a backup of your phone using TWRP and safe it on your pc or internal SD Card, bc in the next step you will wipe your entire system, to get a clean installation.
2. Press WIPE in TWRP and select ADVANCED WIPE. Select everything but "Micro SD Card" and perform the wipe. This will wipe your entire system!
3. Move the .zip file to the Download folder on your phone and press INSTALL in TWRP. Search for the .zip and flash it.
Note: you'll see two red error messages. This is normal!
4. Wipe cache and dalvik as recommended.
5. Download your desired Open GApps package from here. Use "ARM" and "7.1", i recommend the "mini"-package.
6. Move the downloaded file to your Download folder on your phone and flash it just like you did the LineageOS file.
7. Wipe cache and dalvik.
8. In the main menu of TWRP choose REBOOT and then SYSTEM.
9. It will take a while to boot up, don't worry, just leave it there.
10. You succesfully installed the latest LineageOS build on your phone - you can now unplug your phone from your PC also :good:

- 6. Flash LineageOS and install GApps -- I flashed straight from a uSD card inserted in the LG G3.
Thank you for the great Setp-by-Step!

as far as i know LineageOS doesn't have an inbuilt root access (so far) like cyanogenmod did. you can only enable root access via adb in the developer options.
i did not root lineageOS myself so far, but you can try the following:
- Download superSU.zip from their official website and flash it via TWRP.
i would appreciate it, if you would share the outcome

LineageOS does have built in root management, but it doesn't ship rooted by default.
This change was made so SafetyNet doesn't get triggered by root and you can use Android Pay on your device.
Just download the su zip from LineageOS download page and flash.

I am stuck on this step. My d855 gets into download mode and LG UP recognizes the phone, but I'm getting the "You have to select a known model, please" error in LG UP. I have uninstalled and reinstalled LG UP and the DLL multiple times, same problem. I also tried uninstalling and reinstalling the driver, and I tried other drivers, same problem. I tried the tip in another thread (https://forum.xda-developers.com/showthread.php?t=2785089) to change the port to COM41 in device manager, but it didn't help. Btw I also unrooted my d855 (it has 4.4.2 currently) in case that's why the tool couldn't recognize it. Please help!!
Also @hyelton if you can help...
 @engmia since you were helping me earlier...

hi supperbowl,
are you sure you're using a USB 2.0 port and the original LG-USB-Cable, that came with the phone?
as far as i experienced it, 4.4.2 should not be an issue.

Have you tried it with the phone booted into the OS? With USB debugging on? Also if running 4.4.2 why not just use the old method?

No I've only tried it with download mode. I have USB debugging enabled in the OS. I am now trying the old method with LG flash tool, so far I'm getting stuck with the LG mobile support tool which keeps saying "upgrade stopped due to an error".
Edit: LG UP doesn't recognize the handset at all with it booted into the OS.

If it's at least detecting unknown device while in download mode it most definitely should show up in lgup when boot up.
Choose MTP mode? And it's not just in "charging mode" or try vice versa?

what also worked for me once was just retrying the process --> turn off, go into LG UP, go into download-mode. if LG UP does not recognize the phone: put the battery out of your phone, close LG UP and start the process again (also with different USB ports and other USB-Cables).

Hello,
Need to have unlocked bootloader ? Work on SEA version ?

You did not installed LG UP DLL properly
