After being stuck in qloader 9008 mode, I decided to flash the kdz to a micro sd card using eMMC software download as I saw other people do it with their phones and it working fine. However, when I put the sd card into the phone, the screen was still black but this time instead of qloader 9008, it detected as AndrodNet USB Serial Port. When that came up, I thought I could use LGUP but there's a problem with every LG tool I used.
LGUP Would Show unknown model and show a com port number and nothing after it. When I did select that port it would say "you have to select a known model please"
When I used LG FlashTool 1.8.1, every time I would load a firmware and press the yellow arrow, It would say "Failed PreviousLoad()". (I know this software works because I have tried it on different phones and it would work)
When I use LG Bridge, I'd select update error recovery and it would go on "checking device information" and would return back with "connect your mobile device to the USB port. If it is already connected, contact LG customer service.
When I use LG Flash Tool 2014, It would say "problem with communication between cell phone and PC"
Does anybody have any other ideas or tools for me to try? All help I can get is appreciated. Or was it better to be stuck in qloader9008 mode?

I flashed custom recovery image successfully and after that, when phone has to restart, it just stuck at LG logo.
When I tried to enter in custom recovery menu, but it shows only LG logo.
I tried to connect with PC, but it was unsuccessfully. The PC doesn't recognize the device. (nothing happens).
Can anyone help me?
This happened to me also. I solved it like this:
First thing to do is get sure the LG drivers are installed ( there is a topic in the forum on this also).
Install KDZ ( serch in the forum and download it)
Download a room ( stock or not )
Flash the phone with KDZ ( after the drivers have been installed the phone should be detected on the pc.
After flashing if it does not start up do not fear, get the battery out, re install the battery and do a hard reset power+home+volume down buttons pressed at the same time and it should work.
If its your first time install Stock GB 20E as it is an open room, if not new to this I would suggest CM7.
Hope it helped
Regards
But the PC doesn't recognize the phone.

I had this same issue too, do not worry.
Keep your phone plugged into your computer, and go to Start > Control Panel > System > Hardware > Device Manager > Modems and disable the LG modem.
I am on Windows XP, so it may not be the same steps, but the point is that you have to disable the LG modem in Device Manager.
I had the same problem as well at one point. What operating system are you running on your computer?
I had the same issue, but I could not find the LG modem to disable it, it was just that windows was not detecting my phone at all, or using the drivers I had installed for my P500 to figure out what was connected to my laptop. Bricked phone after a failed ROM flash. Reinstallation of USB drivers for my phone failed to do anything.
Have you used LG Mobile update at all? I got all my drivers through it, rather than useless PC Suite 4.
Download it through HERE
Here's what I did to rectify it (Running windows vista):
DO NOT PLUG IN YOUR PHONE UNTIL STEP 3!
1. Went to system restore in windows(you'll find it under Backup and Restore in the Control Panel) and restore your computer to a state before installing any drivers for your phone.
2. After everything had completed, installed LG Mobile update. There is an option to install general USB drivers for your phone, DO NOT do it! Go to Customer Support > Application, Manual & USB driver download. Input your IMEI number from behind the battery in the back of your phone(or just select the "Read your phone" option if you can get it to read your phone). It will search and return the correct drivers for your exact phone. Download and install your USB drivers.
3. Keep your phone disconnected from your PC, and start up LG mobile update again. Connect your phone, LG mobile update should verify the connection by trying to connect to your phone, checking software versions, etc. It will connect even if you are stuck at the LG screen.
4. If everything checks out run KDZ updater and flash your phone back to original specs.
hey first go to emergency mode by pressing back(return) and volume up
and then in emergency mode use kdz it then only pc will recongnise your phone
believe me this thing also happens with me and I know that time I very scared
that time I used this article

The same problem. But i solved it.
1) install again the driver using B2CAppSetup
2)This is based by xda forum by: Zecanills with a detailed explanation from my side.
- You need to download the firmware of your device. Download "Orginal LG Firmware" application (search in xda forum). Open it, put your IMEI and you will download the original ROM.
- Download KDZ updater and uncompress it
KDZ_FW_UPD_EN.zip - 4shared.com - online file sharing and storage - download
- Install msxml.msi from the uncompressed directory
3) Remove the battery, put it back and start the phone in emergency mode (actually the only way possible) back+up volume+power
Connect your device and run KDZ_FW_UPD.exe (as administrator). If the phone is not recognized repeat step 3) several times.
Select Type : 3GQCT
Select PhoneMode : DIAG
In KDZ file : Choose the ROM file you downloaded in the step 2)
Press Launch software update and wait (It will be 10 minutes or so).
Wait until it reboots.
After reboot will appear an image as in the following link: http://androidforums.com/getitnowmarketing/330813-all-one-recovery-thread.html
Don't worry. Restart phone again pushing power button (or remove battery, put it back and push power ) and then after few minutes you will have the phone as the begging when you bought it.
Thanks people for helping me. I just put the phone in emergency mode (Volume UP button + Home button), connected to the PC and flashed with KDZ.
After that, the phone works fine.
Thank you again!

Hi everyone, I have the unfortunate moment of having a failure during an update by LG PC Suite. Initially it was stuck with the picture "Downloading mode", but as the update keep failing at 4%, I read some online threats to press the volume up and power, and now I regretted it. I am stuck with the phone being detected as "hsq-usb dload", no way to go back to the "Downloading mode" picture, even though I tried pressing combinations like volume up+volume down..etc...
I did a search and found alot of people having the same problem, but unfortunately, I am unable to find a solution that fix mine. So far I have installed the Qualcomm hs-usb qdloader driver and it shows up under Device Manager as Port 8.
I have tried the following:
1) Using QPST, detected as phone in "Downloading mode", but I do not know how to proceed as the images and hex files online are not for my model. In addition, it requires the SPC code...so....
2) Using a trial version of CDMA workshop, it detects my phone as "Downloading Mode". I tried to use it to switch modes to Reset or Power Off, but it didnt work.
In addition, the trial mode does not allow me to "read" the SPC code. An earlier version of 2.7 is totally not able to "Read" my phone, showing all details as "Error:" when a read is attempted
3)Using Linux, Ubuntu (via VMPlayer). I was able to see it being detected under lsusb command, which shows as a qualcomm modem. I tried using scripts from various sources like brickdetect.sh, PblClear, lgL9FixBoot.sh ( I know these aren't for my phone, but I was desperate enough to try), and nope, it didnt result in any change in state of my phone.
I am not really a technical person (but willing to try), and I have spend 2 days trying and researching, and I am now out of ideas. As such, I am posting here hoping if anyone has any solutions? Thanks in advance!
Update as of 2 days of these trial: My phone has a solid amber light at home button when battery and usb (to computer) is connected, when pressing it, it goes from amber to red, to amber and vice versa again for around 1 minute, then it disappears. On my computer I see something disconnecting and connecting. In the end after 1 minute after the light disappears, the qualcomm hsqusb qdloader appears under Ports in device manage.
If I do not connect the battery and just connect via usb, the qualcomm hsq-usb qdloader appears under port without any flashing light on the phone.
Hi, I was looking everywhere since yesterday but can't find a solution. I had cwm + twpr + lollipop cm12. I've decided to back to stock, so as allways: driver, b2cApp, kdz, v20h and v10a, usb, s/w mode, xml parser, shhtp, etc... Standard offline kdz method. But during flashing I stuck on 15% and get the info that my phone anad pc are not connected by usb cable, I tried changing usb ports at pc, reinstaling everything, but I have still the same error. If that woldn't be much enough I ****ed something up and I think I don't have any recovery right now
I can put my phone in s/w mode but I stuck on 15% with usb not connected error.
I can put my phone in fastboot mode but my pc does not recognize it, its just pluging in and out it from windows.
I can put my phone in stuck on LG logo 'mode'
Any help? How to unbrick it? How to flash stock or at least some custom recovery? Of course unlocked bootloader. Please help me :crying:
Key it ****ed up even more.
When kdz show me to connect my cable i clicked retry, plugen cable out and in, kdz found my device, and go to step 2. In half way I had again the same error, so again clicked retry, plug out, plug in. Again founded my device, when I had downloaded 100%, same situation. founded my device, log that tool is extracting kdz and nothing. Waiting about ~1,5h, nothing happend, so I diconected cable. In that moment kdz go to third step and I get windows force close for not repodnig app kdz. I said a loud **** and started again. Phone has not been found anymore by kdz. After a few tries, booted to fastboot, and connected to computer. It has been found as Google Fasbtoo USB, no way to update driver to fastboot. I disconected phone and decided to try again with s/w but nope. S/W not turning on anymore (with or without battery). Fastboot not turning on any more. Just LG logo, when I'm connecting device to PC it is sometging pluging in and out but nothing showing in device manager
Any ideas? Please!

Hi everyone,
My dad's friend has a problem with his phone and dad asked me if I can help him. Right now I only know that he had "LG Security Error". However when I got the phone it didn't react on anything, so I'm unable to turn it on or charge a battery (I have also a second battery, neither of them works). When I plugged it to a PC it showed "OMAP4430". I've never had experience with LG before (only Xperia phones), but after searching I found this (2n option), which didn't work with my device, but this (1st option) worked flawlessly. I managed to get into FASTBOOT mode (phone is listed with "fastboot devices", ADB not) - OMAP FASTBOOT DEVICE. I noticed that it disconnects itself after 1-2 minutes and the proccess needs to be repeated. The phone still isn't showing anything on screen. After few hours of searching I didn't find anything, except that after doing procedure with Vol+ button entered, Windows recognized my phone (I could get only twice and the screen was still blank):
Code:
LGE Mobile Composite USB Device
LGE Mobile USB Serial Port (COM9)
LGE Mobile USB Modem
LGMobile Support Tool was doing something, but in the end it didn't detect anything, also I checked out LG Flash Tool 2014, phone information showed that it was in emergency mode. Screenshots
At this point I'm guessing that the phone is hard bricked as it couldn't go to S/W mode, download mode or show anything on screen etc. I haven't found any tut about unbricking in fastboot. Is there anything I can to at this stage?
Thank you in advance!
The com port driver is the only one needed for unbricking. Provided, that the phone is already in D/L mode, otherwise communication will first be done with the ADB driver.
I had the situation, that the phone wasn't recognized by the ADB and Fastboot drivers(with a custom rom installed), and under Win8.1 and Ten Fastboot generally doesn't work. But only the L9 is affected by this.
But if someone managed to clear the whole internal flash, with bootloader and baseband, the phone is economical junk now. Though re-flashing via JTAG is possible. While some geeks may own one of these Octopus adapters privately, even if you know such a person, he should be an LG user, too, as support for each brand or individual model has to be bought separately. Or simply invest around 100€ or $100. That is the price of a brand new phone with the L9s capabilities and a stable(!) Lollipop or Marshmallow installed.
I bricked my LG Optimus L90 and whenever I turn it on it gets stuck on the white T-Mobile screen. AFAIK this should just be a soft brick and it should be fixable. I'm able to boot into download mode and connect my phone to my PC via USB cable. When I do this, though, it fails to install the "MTP USB Device" driver and the device status says "This device cannot start. (Code 10)". What am I doing wrong? Should I be doing this a different way? Or could my phone actually be hard bricked?
