My phone information is:

______________________________
also when i install a kdz called "V20A_01.kdz" any error appears in the KDZ Updater Tool, the phone restarts after the flash is full but dont working.
The phone is stocked in the LG Logo and dont make anything, i only can enter to the emergency mode again using:vol+ + connecting the USB after.

I really need help, i already go to the "technologhy center" in my country and any body haves a idea of what happens with my phone Lol.

What procedure you use to flash KDZ? Have you try emergency mode in updater? Have you CWM installed on device?
And yes, it is worst scenario when you try to flash rom for other device...

I are following these steps:
(when i turn on my phone only the LG logo appears)
1.- Turn Off my Phone
2.- Configure the KDZ Updater settings, Type 3GQCT and mode CS_EMERGENCY (I already tried the all modes)
3.- remove the batery
4.- Connect the USB and press vol+
5.- Now are in emergency mode (windows has detected the device because i already have the LG drivers and PC Suite)
6.- Click on "Launch Software Update"
7.- Wait while the firmware is installing..
i already use a application to found my original (official) firmware from LG page (V10A_09.kdz TCL/TELCEL MEXICO)
But when i tried install this kdz an error appears in the Updater KDZ (in the 14% of progress) and the phone its bricked on emergency mode..
I already tried a lot of differents KDZ Files, V20A_00, V120H_00, and nothing...

How i can do?

Try this:
1. Download older version of kdz updater: https://www.dropbox.com/s/w8h5t1mqcuclijv/KDZ_FW_UPD_EN.rar
2. unpack it on root of c:
3. Pull out LAN cable, or disable internet connection
4. Run msxml.msi from unpacked kdz_fw_upd_en folder
5.put the KDZ you download previously and be carefull to choose only KDZ FOR YOUR DEVICE on root of C:
6. Turn off the phone, hold the volume "down" and insert the USB cable, should see a yellow background and the words "Emergency mode"
7. Run KDZ_FW_UPD.exe
8. choose parameters 3GQCT and DIAG, select the firmware file (KDZ)
9. Click Launch software update and wait...
10. If update stuck again on some %, (stuck means no progres for long time, like 10-15 min), unplug USB, pull out battery, reinsert and repeat from step 6. If you are lucky, mabe previous flash turns back partition organisation destroyed by flashing firmware for other phones, and second flash finish succesfull. In that case, do factory reset,,
11. good luck

DONT TRY TO INSTALL OTHER PHONE FIRMWARE (V20A_00.kdz)! Flash only kdz for your model, like V10a_08.kdz, and download it from http://lg-phone-firmware.com/index.php?id_mod=21, in Mexico section.
No known similar firmware is available for your phone!

My original phone firmware is V10A_09.kdz and the kdz updater shows a error if i try install it T.T

Have you try to install V10A_08.kdz? This is older version of WORKING firmware for your device, just try...

There's no v20 ROM for L7 II until right now while I'm writing this message (and it's just a name that indicates the version for that specific model - e.g. v10 is ICS and v20 is JB in P700, while v10 is JB in P710 - so don't try to compare them in any way).

You simply flashed the wrong firmware, you flashed the firmware of another LG model in your phone, probably a L7 I ROM via KDZ.

The bad news is until today I found no way to fix the phone, see my topic: http://xdaforums.com/showthread.php?t=2743453

maxx_hr · Jul 3, 2014

OK

On this link (maby) you can find another way to flash KDZ: http://xdaforums.com/showthread.php?p=51612244

Yes, you must change some things to work, but this is the last chance for your device.

And I remember that i was read one similar post before few months, for L7 II, but i can't find it anymore. In that post someone describe how to resolve his bricked phone problem, with link to post where he was find solution how to succesfully flash firmware... this post you cant find in LG L3 II - 5 - 7 II section.
So, just keep trying, and please, share with us what you do. If you dont understand procedure, just ask, and maby I have (or someone else) answer.

Good luck

Hi thanks for the suggestion...

It looks like the phone isn't able to enter Download Mode (required for FlashTool?), because it always turn on in emergency... Or am I doing something wrong? I'm not sure about the key combination for L7 II, I can't find it anywhere...

It doesn't work. It goes straight to emergency mode. And those instructions are in a L3 II topic, what if the combination for L7 II is different (involves the hotkey IDK)?

I think emergency mode is download mode...

REMOVE ALL DRIVERS OF ANDROID YOU HAVE (Lg Adb all). Reinstall the drivers I provided there and adb. After that just plug usb in and turn phone on. Tell me as what is getting recognized (in device manager).
