Hi,
Sorry to hear that.... It must b really frustrating. Well, here is the solution, turn off the phone by removing the battery. Then use this combination to get into the emergency mode "Press and keep pressed "Volume up"+"Return" and connect USB cable to phone".
Then I assume that u have the original copy of the firmware. then follow the below steps,
Install drivers properly
Get rid of all usb drivers like Nokia, microsoft visual ++ run time environments
Install the LG drivers by selecting the update manager from the lg site
Disable LGE Virtual Modem. In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.
Run KDZ_FW_UPD.exe (as administrator).
Select Type : 3GQCT
Select PhoneMode : DIAG (in case of fail try EMERGENCY, and as last chance use CS_EMERGENCY)
In KDZ file : Choose the ROM file you downloaded in the first step
Press Launch software update

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.
Here is the log from KDZ:

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

read general thread it has been answered many times,stucking at lg logo is solved by take out battery reinsert and the 3 button combo
have u tried HOME + VOL DOWN +POWER BUTTON,still if it dont,
read downgrading details here http://forum.xda-developers.com/showthread.php?t=1038338
error guide here http://forum.xda-developers.com/showthread.php?t=883314
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!

the error is: "upgrade error WParam : 100 LParam : 502"
By the way, the reason i need to flash the original ROM is to try and get dir of the start-up Emergency Mode error. Meaning, if i shut down the phone, and turn it on it gets intro Emergency Mode. I have to pull the battery out for like 15 - 20 minutes to boot again normal. You can imagine this is annoyng. Once booting, the phone runs perfect...

Maybe you have some opinion on this one?
Thanks!
Did you ever figure it out? I am having the exact same issue (phone goes to Emergency Mode) and the exact same error when trying to flash with Kdz.
Click to expand...
Click to collapse
I had the same
Code:
upgrade error WParam : 100 LParam : 502
on a Windows 7x64 fresh install I think its caused by a bad ROM flash which happens to clash with drivers.
KDZ->Read Phone Info always gave device not known errors then crashed.
I chose to use another PC to make sure driver issues were gone (PPL say that win7 works but I changed to a Vista laptop for a better result) Here is what i did:
**Use a Windows XP 32-bit PC for best results**
1. Use the LG Support tool Run as administrator to DL latest drivers
-
2. Reinstall 3 drivers in order from C:\LGP500\USB_Driver and C:\LGP500\USB_Driver\LG_SmartPhone.
-a. LGUnitedMobileDriver_S4981MAN32AP22_ML_WHQL_Ver_3.2.1.exe (version will vary)
-b. LGWindowsMobile_USBDriver_WHQL_ML_Ver_1.0.exe
-c. LGSmartPhone_ModemlinkDUNDrive_WHQL_ML_Ver_1.0.exe
Restart if required
-
3. Download crecked's Original LG Firmware.exe and get your .KDZ
-
4. Download Software update KDZ and install msxml.msi as administrator
-
5. Remove Sim, MicroSD, and battery.
-
6. Connect the phone and boot it in emergency mode (still no battery)
-
7. Goto device manager and disable Modems->AndroidModem
*MUST RESTART PC HERE!*
-
8. Check ALL modems are disabled in task manager and then set KDZ_FW_UPD.exe to always run in compatibility mode for Windows XP SP2
-
9. Ensure Phone is in yellow emergency mode and no battery... (USB connect noise as soon as plugged in)
-a. Run KDZ_FW_UPD.exe as administrator (MUST be XP SP2 compatible) and set type: 3GQCT and PhoneMode: EMERGENCY.
-b. Select your previously downloaded KDZ file from using the program in step 3, and Launch!
-
10. If finished then wait 2-3mins and turn on phone (if not already booting), Insert battery, and close KDZ. Initial startup may take 10 mins
**Again, Win7x64 did not work for me (even in XPSP2 compatibility mode which is a MUST) so I used Vista 32-bit but XP 32-bit is preferable**
Thanks guys, this forum was amazingly helpful and a huge learning experience for me, mods can feel free to delete this post, or even move it to where it should be I just wanted user DarkAgent, and RUwin to know, and to have the result searchable so others can receive the same amazing tips I had!

I hear a humor that when the phone is in emergency mode and it's conected to pc and the pc is not recognizes it you have to shake you phone to get it working... see if it is true...
So many people around here are having issues with KDZ, errors such as:
--Connections problem between PC and Phone
-Drivers problem.
-Cannot find the phone.
-Bricked too hard.
-Random chinese info stuff...How did i find this solution ?
After i copied the wrong aboot.bin to my device KDZ stopped working even after i repaired it.Why did i try to use KDZ after i repaired it?Well because i bricked it again by installing some modules that weren't compatible and it ended by deleting some of my system apps and also my navigation bar.So, i thought myself why LG designed an program for software update and why don't we use it?So i used B2CAppSetup, and not only that it fixed my device but also it reverted the firmware that i lost when i bricked my phone first time, because when i bricked it the first time i couldn't find the same KDZ i just flashed one that seemed compatible.I have to say it was way more faster and easier.
Click to expand...
Click to collapse
Let's get to the guide shall we?
Step 1 : Download B2CAppSetup( i attached it for ya )
Step 2a : Install it !
Warning Step 2 : If you already have KDZ installed using @hyelton method DON'T INSTALL IT!, you should already have it in your KDZ folder .
Step 2b (If you already have KDZ installed using @hyelton method and can't find B2CAppSetup) : Just delete it and install the program from here .
Step 3 : Open the program and plug your phone into the PC/Laptop whatever.
Step 3.1a: If you can boot up your phone( i mean if it's not bricked ) just select Software LG mode and in the B2CAppSetup window there should appear something like "Your phone has been discovered, do you want to install the driver?", you would say Yes and wait until the driver is installed.
Additional Info for Step 3.1a : For B2CAppSetup to find your phone you don't need only to have the Software LG mode enabled, you will also need the driver that should automatically install by itself.
Step 3.1b:If your device is bricked and can't boot you'll have to enter the Download Mode, to do that just keep holding the Vol. Up button while inserting the USB cable in the phone( The USB cable must be already plugged into the PC while doing that), and you keep it until you go into the Download Mode.
Step 4 : Now let's get the upgrade done. So basically since our phone has no firmware updates we have to trick the program. In the upper right corner you should see two options available, you are going to click on the one that says "Additional Functions"( the one in the left) and then select the second options that says something like "Recovery from an update error".
Step 5 : Now if you've followed as i've said it should be very easy from now on.The program will connect to the device and start downloading the right Firmware Update that you had when your phone first came.
WARING !!! : DURING THE INSTALLATION THE PROGRAM MAY GIVE YOU THIS ERROR " The device has been disconnected from the PC, do you want to abort the update" , you just let it that way because it will still be installing even if that error pops-up.
Step 5.1 : When the installation reaches like 80% your phone should boot up, but don't disconnect it yet, just wait until the program crashed itself,it should crash when it's 99%, after that you can unplug it.
Errors after installing:
1 )com.android.phone has stopped responding
2 )acore has stopped...
3 )contacts has stopped...
n )......
( and it keeps saying that without stopping and letting you do anything )
To fix it just, do a hard reset by using the stock recovery. Hope this method helped you in any way since the links where we could download the KDZ files are mostly down and since the KDZ works when it want and how it want.Feel free to ask question.This method was tested on the D620.
... and then select the second options that says something like "Recovery from an update error".

This is where the option should be .

Well, this is a guide on how to reflash the stock version in case KDZ is not working, i guess if the USB still recognizes the phone it may be a chance to work, just attempt to use the software and see if it works (after all this is another method beside KDZ)

Same happend to me but I downloaded and installed driver from LG .
If my phone has a cab file will it convert it to kdz for me
I'm having the same issues. My LG G2 Mini D618 is stuck in the LG logo
I can't seem to enter Download mode even though I follow the instruction (press volume up button as I plug the USB cable) and installed USB drivers. Please help!
Hi guys,
Sorry to revive the old post, but I haven't been able to find me a solution after many days searching... A customer came to me with an LG G2 Mini D625 (located in Chile), for what i've been investigating the phone is stuck in APX mode, I got to install the "NVIDIA USB Boot-recovery driver for Mobile devices", and now I'm trying this method to attempt to revive the phone... however it has come to my attention that after:
1. Removing the battery
2. Keeping pressed vol+
3. Connecting the usb cable to phone & pc while doing step 2
I can't get the phone to boot in Download mode... Could it be it's a different method for D625? Is it plain dead & hard-bricked without any options left? Can something be done with some sort of box? I don't have any type of box myself, but if needed be, I can advise my customer to go with another technician who owns a box...
EDIT: I have the phone with me... just FYI
Now, i have seen countless cases of people being not able to flash their MMX A311, as for me I was having the same problem too, turns out that the driver is the main problem.
I was trying out YGDP but i was stuck at "Enabling Download Mode"
and while trying out SP tools i was getting an error "s_brom_cmd_jump_da_fail (0x7f3) " .
Then again, I tried many things, and got my phone working in 10 minutes. :good:
So if u too are stuck, then try my method.
It is highly recommended you do this in Windows 7.
I did everything while my phone was switched off but battery was inserted.
Disconnect your PC from internet just to be double careful about the flashing.
First getting the proper driver:
Now, before installing the driver, make sure that you dont have any other driver installed rather than the one which i will provide, if you think you might have installed some other driver then try removing it by "usdreview" (but it didn't work for me though that's why PLEASE TRY THIS ON ANOTHER COMPUTER OR LAPTOP, MAYBE IF YOU HAVE ANOTHER LAPTOP OR COMPUTER OR MAYBE TRY IT ON YOUR FRIEND'S SYSTEM. THIS SOLVED THE "ENABLING DOWNLOAD MODE" PROBLEM FOR ME)
Download this driver, I did with this one:
Remove the (dot) and put " . " in the link. .
www(dot)mediafire(dot)com/file/8v32j8h5doflzi0/Mediatek+MT65xx+Preloader+Driver(dot)rar
Click to expand...
Click to collapse
Extract it and remember where the folder has been extracted to, as it will be needed to install the driver.
Installing the driver:
Open up Device Manager.
right click on My Computer > Manage > on the side pane click on "Device Manager"
Keep it open.
Now first CHOOSE A SINGLE USB PORT WHICH WILL BE USED BY YOU THROUGHOUT THIS WHOLE PROCESS. DON'T CHANGE IT!
Now use your usb data cable and insert it into your chosen USB port and then to your phone.
As you will insert it you will see a device popup in 'Other Devices' or some other tab named as "MTK65xx Preloader" or something similar like that.
NOW BE QUICK IT DISAPPEARS IN 3-4 SECONDS !!
Quickly right click on mtk65xx preloader and select "Update Driver Software"
Now as in the new window opened up, select " Browse my own computer to install the driver"
Browse to the DOWNLOADED DRIVER'S folder, select the folder "Win7" for Windows 7 and Above.
Now the driver will be installed.
Now after being installed, take out your phone from the usb cable, dont remove the usb cable from the computer because you make mistake while again inserting it back into to a different port.
Getting the stock rom and YGDP tool:
Now get the stock rom for A311 and YGDP tool from any verified site.
I downloaded mine from :
Remove the (dot) and put " . " in the link.
www(dot)needrom(dot)com/download/micromax-a311
Click to expand...
Click to collapse
Download from this site needs user to be logged in, it barely took 2 mins for me to register and download it.
If you have any other site you trust then go on and download it from there, but I recommmend you to follow my steps and sites as I did everything and succeeded.
Download the ROM and also the YGDP tool.
Extract the downloaded file to some specific folder as this is the ROM and the tool required.
Installing and Using the YGDP tool:
I have seen people recommending latest YGDP tool but on the contrary I recommend the downloaded old version from the previous step, it worked for me like a charm!!
Install the YGDP tool from the extracted folder.
After installation, YGDP desktop icon will appear, open it.
put the password as: 369
Now, on the top pane, press the button "Config"
In the window opened, on the side pane, carefully select "8297W" for A311
And after selecting that, on the left side section,
in the " Please select CPB file : " , click on the button beside it and browse for your extracted folder of ROM and select it !
now it click " Apply " button .
It will take 1-2 minutes, and after this you will be brought back to the main window!
Now click on " Start "
And wait till in the bottom message log it says " ENABLING DOWNLOAD MODE" , now follow the next step !!
Flashing your phone:
As YGDP stays in enabling download mode, now insert your phone back to the usb cable which was left out in the computer.
Now, if you did everything correctly, YOUR PHONE WILL BE DETECTED and YGDP will start flashing by itself, wait till it says 100% with a green bar.
Remove your phone from the USB cable and then click "STOP" in the main window of the YGDP tool.
Power on your phone.
Your phone will be successfully be flashed and alive !!! :fingers-crossed:
FROM NOW ON, ALWAYS MAKE A BACKUP . :silly:
Feel free to ask questions. :laugh:
If u have suggestions, I'm open for it!! :laugh:
