Unable to connect to phone in SW mode. - LG Optimus L9 P760, P765, P768, P769

ok, I used pimp my rom and well one little setting in the GPU area caused it to blackscreen.. so I decided to just clear the phone hard reset.. but no luck.
so now im stuck, LG comes up and SW does.. but I can not get the PC to clear the phone it keeps saying usb disconnected please connect.., I was using the Metro PCS rom.. 10D I believe, but anyways anyone that can step me in the right direction would have my gratitude.. ive tried the lelus method.. and just not working right.. maybe its the drivers.. but I made sure all of them are installed..

Leave your phone on while performing the offline flash, don't put it in s/w mode first. Your phone will go into s/w upgrade mode on it's own. Oh and use my modified/hex edited 11th bin

no go, i got a video ill put up in a bit, if i unplug it in SW mode and plug it back in i get close, but then when it starts flashing the program crashes...
I can not get it to flash while its on regular.. it keeps saying check usb, the phone its self starts up then goes to LG then a blank screen no metro or tmobile.., there is no feed back when you press the screen either, if you try to hard reset it only restarts the phone..

have you check if the kdz is named properly (all caps) eg. V10G_00.kdz
if it's like this v10G_00.kz it will not work.

I have the same problem, I have installed a wrong kdz and I try to install another one now but it returns me an error: usb and cellphone are not connected, or something like that, at 15% of instalation.
And my phone is in s/w mode with all drivers installed.

Plesae left your phone turn on and put it in LG software mode. Then in R&D Flash tool select DIAG mode instead of EMERGENCY. You phone should boot to S/W update mode automatically.

I cannot start my phone! Because I have installed a wrong kdz.
My phone does not boot, I can only enter the S/W Mode.

OK. Two options to solve this problem.
1. You can use LG Mobile support tool to recover your phone. Load it from LG website select recover phone from menu.
or
2. Flash ICS u boot & x-loader via fastboot. Please refer to to fastboot tool at http://forum.xda-developers.com/showthread.php?t=2292828 after that your computer should reconize your phone in S/W update mode and you can flash kdz.

I mean in fastboot script by Lelus, there're option to flash ICS u-boot & x-loader. Did you flash it on your phone? Because on JB KDZ flash tool cannot detect our phone. It work fine if our phone have ICS u-boot / x-loader.

I followed the steps given on that thread
My pc shows new device found ANDROID. Device is not getting detected
But on this step in cmd

it shows < waiting for device >
i too got such problem.
while holding down back +Vol down connect your phone to pc .It will enter into emergency mode.Then your Computer might detect it.
Can anyone of u help me ???? My phone is still stuck with Fastboot mode
Basically on a windows machine you download kdz updater and uncompress it as it is a zip file.
Download from here.
This is what I did on an xp laptop.
I had to down load the drivers from the official lg site. when here you enter the code that is on the box the phone came in or under the battery.
Chose the your county and laguage from the drop down box at the top right of the dialogue box. Then from the middle you can choose the drivers. For some reason I had to find the files and click on them to install the driver.
Ok once you decompress kdz updater there are three seperate files to work with. 1. windows enabler. 2. msxml.msi 3.KDZ_FW_UPD.exe
You will also need to download the right file to restore with,You can find it with google.
Please check here the The_ERROR thread wich explains it very well:
[ROMS] Original LG Firmware list.
Install msxml now.
Now you have to boot the phone into rescue mode. On Lg Optimus One turn phone off even if it means taking out the battery.
Press power - volume up - back (this button is next to the home button).
Connect to usb now.Computer found new hardware and installed four drivers.
Then open device manager. Left click my computer - properties - device manager. You need to disable the lg modem driver. Left click on it and disable.
Now launch kdz updater. There will be a drop box on left set to 3gspt or similiar. on the right drop box set to diag. The long box just above the info box with a file at the side lets you browse to find restore file. e.g. V10a.00.kdz.
Double click the button below and let it do it's thing. Took 15min. My phone shut down and came up with an error at the last minute. Anyway I rebooted and all was good.
Everything was the way I left it. Just had to re-root.
My only real problem was getting the kdz installer to see the phone.
After installing the drivers restart pc. If it finishes quickly and just before saying finished it says phone not found try removing all phone related drivers including nokia pc suite and the lg suite and remove and reinstall the drivers.
Hope this is of some help to you.
Finally, Recovered my phone by flashing KDZ through Emergency mode.. No other method worked..

I had the same worries coz my pc did not detect my device at all..
I was trying to get pass the Fastboot mode.. But in the cmd when i tried to erase and re-install recovery it said waiting for device.. Luckily and finally after many tries i could enter emergency mode. Only then the phone got detected but fastboot didnot work there.. The Only way out was to Do the KDZ flash. I flashed the indian GB V20b and did a hard reset now. Flashed recovery and for now have left it with the stock rom..
I wonder now this problem arises due to custom roms.

this problem was cuz didn't perform the steps carefully.
This can called bricking but not fully . As it can be recovered.
Bricking is when your phone is as useless as a brick.

[q] softbricked? i think?

So I recently wanted to load a custom rom on my p769.
Unfortunately, I tried to flash a rom without actually having the bootloader unlocked (thought i did?)
Now i'm forever stuck at the "LG Security Error" screen.
I can't seem to do anything else! :'(
The only other mode I can boot into is S/W update screen (holding volume up and plugging in usb cable).
I tried to get to another mode I read about (vol up + vol down then plug usb cable for "download" mode, to no avail)
Anyway, once I do get it into sw update mode, I can't seem to do anything either way, when i try to list adb devices, none are listed, when i try to use lg mobile tool, it never connects, when i try to use kdz offline update tool, it doesn't see the phone, it just keeps trying to connect, the log freaks out at "_IsConnectedPhone Call", and just keeps trying to "connect" to phone but can't
Am I totally screwed here?
What can I do? Any help appreciated!

You're on JB, right? KDZ offline flash tool cannot detect phone in JB. you have to flash ICS x-loader/u-boot then that tool can detect your phone. please visit http://forum.xda-developers.com/showthread.php?t=2292828
For LG mobile support tool problem, it need to download rom from LG server. Have you remove/comment 1-2 line that you add to hosts file? You said it never connect that mean it don't see your phone?

I've tried this as well, but I don't know if i'm doing it correctly
I installed the 'drivers' it needs (following the readme file) when it shows the "unknown/other" device (the part where you have to catch it in device manager).
After this, I run the start.bat, enter 5 and hit enter, i unplug my phone and hit any key, then i plug it in as it says and it does it's thing, then i wait for 4 seconds when it begins to say "waiting for device", i put my battery in and it just stays there, waiting for device
Can you help me figure this out? Am I doing something wrong?

i think i'm making some progress, thanks for helping so far!
anyway, i'm able to get fastboot on my phone (i think?), the screen on the phone shows the flipped LG logo and at the top right it says 2.0 fastboot (flipped of course)
but, what am i supposed to do here?
i see the 2 omap devices listed on my device manager
whenever i try to run the kdz offline flash tool (if i'm using the right one), it still doesn't detect the phone as connected, doesn't even try, just errors and tells me to connect to usb port and restart or exit
what am i supposed to do once i'm in fastboot recovery for my phone?
should i comment out the 2 listings i added to the hosts file? should i NOT be running shttps app? which kdz offline flash tool should i be using? (currently trying: UpTestEX_mod2_marwin.exe)

You should run start.bat and select flash ICS u-boot/x-loader for P769
When it finish, reboot you phone to S/W update mode and try to use UpTestEX_mod2_marwin.exe to flash your P769 kdz again to restore your phone.
Maybe I miss something about P769 model, please search in FAQ forum many people have this issue, and most of them have fixed it.

[Q] Stuck at LG logo

Hi all!!
Yesterday i tried to install android 4.4 but the procces didnt succeed, it stuck at. LG boot logo. So i decided to restore my backup in ckockworkmod,it started the process then stopped at the phase "restoring /system" . I waited about a half hour, and because it didnt take the much time before, i took out the battery. I read somewhere that formatting the system partition in cwm could help, so i did that. Then i retried restoring my backup. It stuck at the same phase. Later i downloaded the official kdz, and decided to flash it. I could bring the phone in update mode, but the process stopped at 15% at lg update manager.
At the moment i can get into clockworkmod, but cant restore /system . The update mode is also okay. I dont know that fastboot works or not. I havent tried it yet. Please help me thanks in advance
@trapistasajt
You will need to get fastboot working and use lelus's fastboot script to flash the "u" and "x" loaders for the device and then perform the offline or online flash
http://forum.xda-developers.com/showthread.php?t=2292828
Also as you found out you cannot flash custom roms without ulocking the bootloader first and you cannot use the L9 CWM bootstrap recovery for Locked Bootloaders, too flash custom roms.
try this online flash methode with B2CAppSetup

i had the same probleme and i fixed it .
My bootloader is unlocked. I tried the fast boot method, but it doesnt go further than "Waiting for omap...." . So, i couldnt go into fastboot (probably my fault). Yesterday i sent it to the service. If they notice that my varranty is void (because of the unlocked bl) and send it back, i will try it once more. I would be very thankful if someone could write a noob friendly-fastboot guide. As i read, lots of people are struggling with the same problem. Thanks in advance!!!
You have to use LGMobile Support Tool (Install drivers from it first) Then enter in download mode conecting the phone to pc pressing vol+ and the rest its automatic.

LG Mobile support tool let you download the correct drivers. Then connect your phone while u keep pressing vol+ and it enters in SW Upgrade mode. Then just click "additional features" and "upgrade error recovery"

It shows something about firmware ir will restore. Ir will flash the latestbfirmware from original carrier release.
For example i actuallybhave v20L but my original carrier only released v10a. It will restore to v10a
None of them works, other ideas?
This fastboot method worked for me in 5 min, pay close attention to the instructions and it works!

Spent days with LG update tool which if you read the log has no url for files to download.
Good luck!
I got my phone back from the service. They didnt repair it, because my varranty is void. I tried the methods mentioned above.
First, I tried flashing kdz, (with the solution for post-jb problem), but i couldn't get into S/W mode, which was available before the service.
Second, since i couldn't load S/W mode, the LG upgrader wasn't successfull, too
Third, fastboot still not work.
I am sure, that im not the only person with this problem, since it happened during installing @artas182x 's JB 4.4 rom. Please @artas182x or somebody write a noob-friendly guide/suggestion which may help to unbrick my beloved phone. Thanks!!!!!

Help_bricked my TMobile LG G2 :(

Hi guys. I got the Tmobile LG G2 and it was running on Android 4.4.2 LG G2 D80110c. Then I changed the dpi by editing the build.prop via root explorer up but when the device reboots, it shows system force close and I basically cannot do anything. I realized that my TWRP recovery hadn't installed successfully and also I think download mode is not working. Computer recognizes the device when it is on... Can someone please tell me how to unbrick my device? Is there a way to install TWRP at the current condition of the phone? I think I cannot use lg flashtool because that requires the phone to be in download mode, while mine can't get in download mode...please help! thank you!
Edit: also when I try to hard factory reset the device it shows: ERROR: boot certification error and it gets stuck in black screen.
What I can think of is a way to manually install TWRP via adb or manually flash a kernel that supports custom dpi, but the only problem is that I don't know how to do that...

theres several things you could do.. try srk tools to try and fix twrp, or fix download mode using nuke download.. i dont know how to i just know theres a way to do it.. if other fails and it doesn not go into download mode then you must short circuit the motherboard.... then look at thread g2 hard brick fix..

I don't think my phone is hard bricked. USB debbuging is on and computer recognizes the device when it boots up. I simply don't know how to install twrp via adb commands or alternative methods ... or how to manually flash a custom kernel that would allow normal device boot up when dpi is changed.

I saw those I just can't get it to be recognized by the computer. Did the guy in the video try the hard brick fix from XDA? It is not very clear how he gets his laptop to recognize the device

Hi guys. I got the Tmobile LG G2 and it was running on Android 4.4.2 LG G2 D80110c. Then I changed the dpi by editing the build.prop via root explorer up but when the device reboots, it shows system force close and I basically cannot do anything. I realized that my TWRP recovery hadn't installed successfully and also I think download mode is not working. Computer recognizes the device when it is on... Can someone please tell me how to unbrick my device? Is there a way to install TWRP at the current condition of the phone? I think I cannot use lg flashtool because that requires the phone to be in download mode, while mine can't get in download mode...please help! thank you!
Edit: also when I try to hard factory reset the device it shows: ERROR: boot certification error and it gets stuck in black screen.
What I can think of is a way to manually install TWRP via adb or manually flash a kernel that supports custom dpi, but the only problem is that I don't know how to do that...

LG E460 bootloop, can't open recovery or anything else

So, I've had this problem before, and I know that I managed to get my pc recognise that I plugged in my phone, and updated it with the LG Support Tool but this time nothing seems to be working. If anyone could give me some advice on this problem, I'd be really happy, as I'd really need my phone right now. Thank you in advance.
Download last Europe Open KDZ for your phone from here. Then try start your phone in emergency/download mode and use LG Flash Tool with downloaded KDZ.

That is the problem emergency/download mode doesn't work either. It could be that I'm doing something wrong, but all I get is the bootscreen.
Try this steps to emergency mode:

2. now enter into "download/emergency mode" of your phone... but how??
(i) remove battery then insert battery
(ii) press and hold both vol+ and vol- buttons and connect to computer via data cable. you will see LG logo and '>download mode' on bottom of mobile screen.you will also hear a 'connecting sound' from PC that indicates that your phone is now connected.

If it'll work, continue with LG Flash Tool.

Unfortunately, the software updater always "stops due to an unknown error". If you have a solution for that, I'd be more than happy to read it.

Yes I did. It said download mode on the bottom.
Then make sure you have installed LG Mobile Driver, if not, download and install it from LG site. Also make sure you have downloaded correct KDZ for your phone and have copied it to "LG Flash Tool 2014" folder and use CSE Flash.

Well, I was using an earlier KDZ, maybe that's what was causing the problem. I'll try using this one.

It either crashes completely, or says that some error occoured. I'm pretty sure I won't be able to use this phone again.
