In the tutorial http://forum.xda-developers.com/show...&postcount=134

Step 3 will not open step 4. It will only open the LGMobile Support Tool after I press Upgrade Start
I did this: Need open and edit file
c:\windows\system32\drivers\etc\hosts
127.0.0.1 change to 86.120.150.251 csmg.lgmobile.com

And this that also: The process of resuscitation:
1) Install the drivers from your LG P930 drivers.
2) Set the folder B2CAppSetup KDZ_FW_UPD_EN.
3) Set shttp3.exe, note jackdaws "I agree with this license, and I accept all items", "Update entry in main menu" and "Add to startup".
4) Run the program http.exe, click the right mouse button on the top of the Small Server and select Server -> Settings ...
5) Go to the tab HTTP, in the "TCP / IP port for HTTP server" change 80 to 9002 and at the top right click on OK.
6) Content www.zip unpack in the folder C :/ shttps / www
It is important to:
Small Server software must be running, or resuscitation is not possible.
7) Open a notepad (as root) file hosts, which is located in C :/ Windows/System32/drivers/etc and at the end add the following:
127.0.0.1 csmg.lgmobile.com
Save and exit.
8) We transfer the phone in boot mode:
Turn off the phone, if you have not turned off.
Disconnect the USB cable when connected.
Hold down the volume rocker up and connect the USB cable.
Hold the volume rocker up until the screen that says: Download Mode.

But after I press start, it will just open the LGMobile Support Tool and nothing about language options.

help please !

It is much to ask for you or someone to upload the host files with the changes? Its giving me a hard time with the admin rights and stuff. If not, please copy paste the exact file-text so I can paste it to mine. I'll then try to work with the admin rights of the file and folder. Thanks !

Copy the text below to your host file with changing original text.
Code:
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#	127.0.0.1       localhost
#	::1             localhost
127.0.0.1 csmg.lgmobile.com

Hello.

It did not work. I copy and paste what you gave me about the host file and saved the host file as a 'file'. Just as the original format but with the ip changes.

The phone is conected and is in Download Mode. It will open again the LG tool.

Can someone please update the links to the stock images? Links to the images (except system.img) are all broken.

---------- Post added at 05:18 PM ---------- Previous post was at 05:15 PM ----------

By the way, have anyone of the guys who had sent their phones to LG repair facility ever tried to factory defaults? I did and my phone is messed up. I'll try to reflash the system.img

this tutorial needs update.
including shttps and www

in reply to above post the reason you are not getting the language option is because you modified the host yet nothing is rerouting your request,
goodgle "LG recovery and shttps www"

honestly way the first page is written, this tutorial is outdated and only contains 80% of the real work.

So just recieved my lgp930 back from Bell back to original everything
Witch mean I got a fonctionning cellphone not rooted not anything
but with a lot of bloatware and software I dont want and that I do not like so I guess this time I wont flash anything I will wait for ICS
but I will root it anyway and I will get rid of the crap they put on it..
ill be more carefull io promise

SO the best way to unbrick you phone Is simple go to the store you bought it from tell him it doesnt work anymore and you dont know why
tell complain about batery life
tell them you instal some kind of app that was supose to save your batery life and then wait for the guys to say thats why your app killer must have killed something it shouldnt...
then there you go on waranty !

Alternately, you can just grab the ADB folder from your SuperOneClick folder, copy it to C:/, and then add that directory to your PATH. Hell, you could even run all the commands from wherever you have the ADB folder, just make sure you have it.
2) LG P930 drivers: http://s3.amazonaws.com/lgforum.com/...nal/LGP930.zip
3) LG Mobile Software Update Tool: http://csmg.lgmobile.com:9002/client...2CAppSetup.exe
4) UpTestEX_mod2_marwin/KDZ_FW_UPD_EN: http://www.filesonic.com/file/225575..._FW_UPD_EN.zip
5) LG SU-640 firmware V10F_00.kdz: http://www.megaupload.com/?d=31XABWWJ
6) A method of rooting your phone. My preferred method is the latest SuperOneClick due to its simplicity. I won't really cover how to root your phone in this tutorial as it's covered elsewhere.

The following should only need to be downloaded if you were stupid like me and bricked your device before you made backups of the necessary partitions (This will be explained elsewhere, but needless to say it's as simple as switching the "if=" argument and "of=" argument in the dd commands toward the bottom):
7) boot.img: http://fileape.com/dl/OCowIxMnbDUMiPW6
8) recovery.img: http://fileape.com/dl/jFMlB8I3kkSMOYWN
9) firmware.img: http://fileape.com/dl/4gHHDDUhODLiJGHM
10) baseband.img: http://fileape.com/dl/TMsvdaKOa7VG4mVT
11) system.img: http://depositfiles.com/files/f0ke241ew

Flashing the SU-640 rom:
1) Put your phone in download mode: power off the phone if it's not already, unplug the usb charging cable, and simultaneously hold the volume up button and plug the usb charging cable back in.
2) Open up UpTestEX_mod2_marwin. (If you know what you're doing, I've been told you can use KDZ_FW_UPD_EN as well, but since I didn't use it, I'm not going to discuss it)
3) Hit the folder icon next to the "Select kdz file" line and browse to the SU-640 v10f_00.kdz
4) Select "CSE web upgrade test", a new window with some options including an "Upgrade Start" button should appear.
5) Take a deep breath...there's no going back :) Press "Upgrade Start".
6) At this point in time another dialog box will appear asking what country and language the LG Mobile Upgrade tool should use. Since this guide is written in English, I assume you'll want to change it from Republic of Korea to All other countries and Korean to English. This affects the language that output messages are displayed in in the LG Update tool only, it doesn't affect anything with the rom (that'll be all Korean on initial startup lol).
7) The update tool will proceed to flash your phone, but it should never complete "normally" (mine never made it past 4% according to the tool and other users have reported similar behavior). However, your phone should reboot once or a couple of times and then just be sitting idle waiting for you to go through the setup wizard. At this point, just kill the LG update tool process in task manager, don't wait for it to complete because it won't.



Restoring Nitro HD partition images:
1) Open up a command prompt and navigate to the folder you saved your recovery images to (hopefully you put them in the same folder, it'll make your job easier)
2) Push all the image files to the phone's sdcard using the command:

Code:
adb push filename.img /sdcard
Alternately, you can just mount up your phone in My Computer and copy and paste the files over.
3) Now the real fun begins! Use the following commands:
Code:
adb shell
su
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13
dd if=/sdcard/firmware.img of=/dev/block/mmcblk0p1
dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
dd if=/sdcard/baseband.img of=/dev/block/mmcblk0p14
4) You won't be able to issue a reboot command, so just hold power down on your phone til it's off and hold the volume down button so that it comes back up in factory data reset mode. You will want to pull your sdcard at this time if you don't want your data erased.
5) Hit power twice and your phone should go through its reset process and (hopefully!) come back up in a working (and rooted) AT&T "stock" rom


If you have any issues, it's possible I've forgotten some steps, so I'll address them in this thread. At this point, I'd like to thank specific people who helped me immensely getting a working phone again: bytecode64, gordec, schwin97, belth219, sukudos, and ziiljuks. (If I've missed you, I'm sorry, I'm thankful to this entire forum!)

Original post:


if i wanted to just return to stock from kernalpanics rom would i just need to restore the nitro partition images and bypass the first steps ??
