I got a LG optimus P500 recently in India. I installed the LG PC suite backup on laptop running windows 7 and connected my phone successfully.
The software wanted me to sync phone data with pc which i did not do. Later I tried updating my phone software (disabled mass storage mode in settings).
Two options here 1. Backup and continue 2. Continue without backup.
The first time I proceeded with "backup and continue". Program stopped running and crashed immediately ( Is is cos PC suite was running on W7? ).
The second time I proceeded with "Continue without backup". It went on to install a new update installer and continued with "downloading update". Successfully downloaded the whole update and my phone went into emergency mode for 15 mins. After this it got stuck there and no progress. I had to remove the battery and restart the phone and found it in same condition as it was before update.
So my problems are
1. How can I backup data?
2. How can I update firmware?
I possibly know about rooting and custom ROM's, but have some warranty issues pending (dust inside the screen), so the above stuff would not probably be fruitful.
Can someone help me with this?. I'm very sure that I am going wrong somewhere !!!!!!!!!!!

Okay a basic course:
I use Windows 7 Ultimate 32bit, and LG PC Suite always crashes for some reasons on it (thanks LG for the ****ty softwares, even the latest version). That's not a big deal though, because sincerely I think everyone here can approve this, LG's PC Suite is practically useless. Stop worrying about it.
For you questions:
1. You can use random applications found on the Android Market to backup your data on your sd card and then transfer it to your pc if you wish to. If you want to go further, root your device (preferably with Gingerbreak) and then use Titanium Backup.
2. Since we dont have v2.3.x update (gingerbread) out for our phone yet, there's no use to upgrade to any official LG stock rom, they are practically all the same. If you wish, once you got your phone rooted, you can flash a rom on it, through a "Recovery" to experience better performance. If you want to know more then just ask.

lg pc suite has resulted in dead phones for many the only way to revive is to use kdz updater and follow error guide and flash your desired updated rom via kdz.iknow your phone is not dead though try the three button combo and check if it helps orelse kdz is the solution.
regarding backup of data-if u mean app and games that can be done through titanium but u need root permission so just root it and backup using titanium and than again unroot it.simple the lg ppl wont get any hint of what u did.
if data -means ur phone os than i am not aware as custom recovery works the best
http://forum.xda-developers.com/showthread.php?t=1038338 this might help u somehow i beleive and the error link is in the thread itself
thanks for that..
thanks to both above...
I would certainly root the mobile once i get my phone to service center for warranty claim ( it has dust specs inside the screen -must be between display and touch panel)...
Happy to see so much going on to help ppl customize their phones so much... If not you ppl then android and optimus would have been dead years back...
Use gingerbreak to root your phone. Titanium to backup. Again unroot via gingerbreak. If you give phone for lg service ask them to upgrade. Or use KDZ flasher to flash LG rom from official site. It does not void your warranty
I hope this will help. Do it at your own risk

LG Pc Suite Stop Workyng
hi, i try to update to 2.3.3 official my LG P500 via LG Updater,and about 5% Stop Program first time, and 2 time, and 3 time.... i unistaling and reinstaling LG Updater app, but no result ...
Now i turn back to 2.2.2 LOL ROM 1.4.2 (i used for 3-4 months) is very stable + root with GingerBread v 1.2, and is super, battery is good for my.
Read over the steps first before reading the description. It will tell you what files, programs, etc. you will need for this procedure. Keep in mind that this WILL be the equivalent of a factory reset. At the end, you will either have the stock Froyo ROM, or the stock Gingerbread ROM.
I'm making this as a note to myself and to help all of my fellow Optimus One, T, and V users. Keep in mind, this was done on my LG Optimus *T* using the files for the Optimus One. It is almost guaranteed to work for One users, and will most likely work for T users if you use the old BB (Baseband) versions. Alright, so here we go, step by step.
Beginning note: Do NOT connect your phone to the computer until it is specified in the directions. This guide is assuming you have Windows 7, administrative privileges, and all programs work accordingly.
These are the prerequisites. Read this, and then move on to the second part.
1. Download KDZ Updater & the appropriate stock ROMs for your device (For One users, I suggest the V20 stock ROM if you have previously upgraded to Gingerbread 2.3.3., and the V10 ROM for T and V users, as it is compatible for our devices.
2. Run msxml.exe from the KDZ folder you downloaded.
3. Download LG Drivers for your phone (I'm not sure if these vary by Optimus model, but they should all be the same.)
4. Find an appropriate program for updating or downgrading your Baseband, and find the appropriate files for it (V10 for old BB, V20 for new.)
You are now ready to begin reflashing the stock ROM. Follow these instructions to the letter.
1. Take out your battery and SD card.
2. Plug your USB into your computer.
3. While holding Volume+ and Back (On one and T models, V users will need to find the appropriate combination to enter Emergency Mode), plug the other end of the USB into your device.
4. You should hear your computer make a sound indicating a USB device has been plugged in. As the LG Optimus has a sensitive USB port, I suggest making sure the Micro-USB end be pushed into and upward to the phone, as I've found this to be the best position to make sure it doesn't disconnect.
5. Press the Windows key on your keyboard, and locate 'Computer' on the right side of the 'Start Menu'. Right click it and select manage.
6. On the left side of the opening window, find 'Devices'. It will switch to the devices tab. On the right, find and enable the option to 'Show all drivers'.
7. On the device list, locate the category labeled 'Modems'. Open the sub folder, find 'LG Modem', right click it, and disable it.
8. Go to KDZ and open it.
9. Once KDZ is open, open the left drop down menu and select the FIRST option that starts with '3G'. On the second drop down menu, go to the bottom option 'Emergency'. NOT 'CS_Emergency'.
10. Where it says KDZ file, look to the right and locate the file browser. Find the ROM (a .kdz file, the one you downloaded in step 1 of the first part of the guide) and double click it/open it.
11. Press 'Start Update'. It should then go through a long list of gibberish, and when it's done, it'll say '-------Finished-------'. The phone will then reboot
IMPORTANT: Do NOT remove the phone from the USB during this step, and do NOT remove it until the phone until it has fully rebooted, and you see either the setup screen or the home screen. You can proceed to put the battery and SD card back in, and THEN remove the USB.
This worked for me, and I soft bricked this thing BEYOND belief. I will update this accordingly to make it more accurate. The base band file and installer you were told to download are for the event that either a) Your networking does not work (No signal, 3G, etc.) b) Your phone gets stuck in another boot loop because the version you installed is not compatible with your installed BB. ex: V10 ROM with V20 BB.
Vocabulary for Noobs:
Base Band: Think of it as like the phone's default firmware. If the ROM is V10, but you're trying to run a V20 BB on it, it won't work because your V10 hasn't been updated to V20 and won't support it. Vice versa may apply to running a V20 ROM with a V10 BB
ROM: It's an operating system for your phone. The stock ROMs for each phone brand all have different extensions. LG's extensions are .kdz
I see almost everyone in L9 forum is giving reference link to this flashing guide in their threads, but almost no one is mentioning any credit to this. They are just putting links. What do you all think, pals? Do I deserve a credit or not

Thanks to all developers and contributors: Bin4ry , adixtra , unknown_world. I thank to all the users of this thread who gave feedback and reported issues time to time, which helped "us" to make this guide better and perfect.
First thing first, this is not my original work, I have just tried to consolidate all the scattered things together for SAFE and EASY flashing and rooting of L9 variants. Written this guide as many pals were having issues with OFFLINE KDZ FLASHING and help was scattered in many pages creating more confusion.
Wow! After so much of followup with xda mods, finally we got Home (Sub-Forum) for LG L9 series.
PLEASE, USE INFO AT YOUR OWN RISK & INTELLIGENCE.
Flashing KDZ removes Root and CWM, so you will need to root again.
Flashing KDZ does not wipe your data, but if you get bootloops you need to hard-reset it, so please backup data first.
LG Update Tool works on all versions of windows (xp/w7/w8-32/64bit) for flashing any version of Android (GB/ICS/JB). If it does not work on your windows, something is missing on your system and if anyone here cannot help you then, you have find your own ways. Don't expect Spoon-feeding for everything.
DEVICES FLASHED WITH THIS GUIDE AND TESTED OK: LG Optimus 2x (P990) and LG Optimus L9 (P76?)

-------------------------------------
[GUIDE] FLASH L9 Factory ICS/JB ROM WITH OFFLINE FIX + UNBRICK
Works perfect on Win-XP/W7/W8 32bit/64bit. UNBRICKS ALL SOFT-BRICKED L9 (P760/765/P768/P769)
TRUST ME THIS IS NOT LENGTHY PROCESS, I JUST HAVE PUT THEM IN EASY STEPS FOR COMPLETE NOOB PERSON. EXPERTS PLEASE STAY AWAY FROM COMMENTING HARSH ON ME.
THIS METHOD IS ALWAYS FASTER THAN ONLINE WITH PC SUITE, WHICH DOWNLOADS HUGE FILE ONLINE AND YOU NEED TO WAIT UNTIL IT FINISHES DOWNLOADING IN THE MIDDLE OF FLASHING.
In first part of this Guide, we are creating a Local Web-Server for LG Support Tool and will try everything which will PREVENT the tool to connect to real LG server over internet. We have to create SMALL SERVER on our own system and redirect tool to this webpage.
FIRST DOWNLOAD YOUR OWN OFFICIAL KDZ (LG ROM) FILE FROM MY ROM COLLECTION PAGE or from anywhere and proceed...
0) Precautions:
___A) Select "Debugging Mode" as ON (Ticked) in Phone Settings (Developer Section)
___B) Select "Install from Unknown Sources" as ON (Ticked) in Phone Settings (Security Section)
___C) Indian version of L9 does not come with "Lookout Security Antivirus" already installed. But KDZ from other countries may have it already installed, FORCE CLOSE AND UNINSTALL it from app manager. If you cannot uninstall, at least DISABLE it. This program is known to be preventing connection and rooting of device.
___D) Remove all other USB devices (external hdd, backup drives, other phones, etc) and cables connected to PC to avoid issued due to voltage loss. (example)
___E) OFFLINE KDZ FLASHING DOES NOT LOOSE PHONE DATA, BUT YOU MUST BACKUP YOUR PHONE IN ANY CASE.
1) Find NOTEPAD program from StartMenu of Windows and Right Click on it and run it with "Run as Administrator" option. Remember use "Run as Administrator" while opening, otherwise you will not be able to save it after changes.
Now you need to open "HOSTS" file located in folder "C:\Windows\System32\drivers\etc\" with following method.
Click File Menu >>> Open File >>> Now copy-paste following in "Open File" Box.
C:\Windows\System32\drivers\etc\hosts
Click to expand...
Click to collapse
Please note the opened file name is only "hosts" and does not have file-extension like txt or anything.
When file is opened, add following lines at bottom of "hosts" file, a file with no extension like txt/doc/xls.
127.0.0.1 csmg.lgmobile.com
127.0.0.1 csmgdl.lgmobile.com
Click to expand...
Click to collapse
Now SAVE file and Close it.
Content of Hosts file looks like this sample file. Close this file , because we may not need it after this point.
AND RESTART PC NOW (check if lines are still there after Restart. They should be there.)
2) INSTALLING SMALL SERVER: Download "shttps.zip" (attached below) and Extract the Zipped folder "shttps" in root of C-drive of your computer.
Now Right click on "C:\shttps\http.exe" file and "Run As Administrator" and in Windows Compatibility Mode with "WindowsXP SP3" (must for Win7/8) , a server status window will open "MINIMIZE IT BUT DONT CLOSE IT" and you will also see a SMALL SERVER icon in TASKBAR, like mentioned below.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
WEBSERVER TESTING: If webserver is running correct, YOU SHOULD SEE A SWEET GIRL WITH L9 WHEN YOU CLICK THIS >>> http://127.0.0.1:9002
If you don't see a GIRL, something is wrong. Start again.
COMING TO ACTUAL FLASH PROCESS.
3) Download (attached) and Extract "KDZ_FW_UPD_EN.zip" and save the folder on desktop or any suitable place on your hard-disk.
4) Optional if "MSXML 4.0 SP3 Parser" is already installed before: Install it by finding and installing "msxml.msi" file in flash folder.
5A) Optional if "B2CAppClient" is already installed before: Internet Must be ON and Right-Click on B2CAppSetup.exe and Run As Administrator. If not installed before, it will download a setup file, will install it and open "LGMOBILE SUPPORT TOOL" box as shown below. Without doing anything just close this box because we will install latest LG Universal Android driver manually in next step.
5B) Optional if "LG Android USB Driver" is already installed before: Install latest "LG USB Driver (Download 4.0.4 here)" Remember your Phone is not connected yet.
NOW YOU ARE ALL SET AND READY TO FLASH
6) Never installed JellyBean before and with Locked Bootloader? Then Connect Phone in Software Upgrade Mode: Switch OFF the phone and Press VolumeUP button and insert USB cable into phone, Now phone should show SW Upgrade Mode.
Let windows load any drivers, wait until it finishes. TWO ENTRIES SHOULD APPEAR IN DEVICE MANAGER IF DRIVERS ARE PROPERLY INSTALLED, LIKE THIS SCREENSHOT or this screenshot. (ignore detected entries in following screenshot, they will be different every time)
Post-JB issue: If you have installed JellyBean before, Phone may not go in "Software Upgrade Mode" or Flashing stops at 14% in 11th step.
Then do this WORKAROUND: Keep the Phone POWERED ON with USB connected and on "LG Software" mode and do next step of flashing KDZ with Update tool and the phone will automatically go in software upgrade mode.
Click to expand...
Click to collapse
7) Execute "UpTestEX_mod2_marwin.exe" with "Run As Administrator" option and in Windows Compatibility Mode with "WindowsXP SP3" (must for Win7/8) >> and Select your KDZ file. Select "3GQCT" in Type of Flash and select "EMERGENCY" for PhoneMode. Ignore all other options and press "NORMAL WEB UPGRADE TEST" at bottom. This button is very light and hard to see at first attempt.
IMPORTANT: Do not change names of the KDZ files from LG server or downloaded from my this and this page. (They should look like.... "V10G_00.kdz" or other version in same style.)
8) Now "Read Phone Information" box will open with blank information, Just press "Upgrade Start"
9) A small box at bottom-right side may appear like below, which you may "ignore" or "cancel"
10) Now "Select country and language" small box will open. Here select "Different Country" and "English" and press "OK".
11) Now actual flashing will start and PHONE UPDATE TOOL (shown below) will appear, and if your KDZ file is good flashing will end without any issue.
JUST RELAX!! SIT BACK WITH HANDS FOLDED BEHIND HEAD AND WATCH IT HAPPENING.
When it finishes full flashing and phone will start rebooting.
YOU CAN REMOVE CABLE AFTER 100%, AND FLASHING IS FINISHED!!! Close all programs.
FLASHING ERROR AT THIS POINT? If you have installed JB before then your flashing may stop at 4% to 14%. This may be due JB rom already installed before or due to driver not completely installed for "SW Upgrade Mode".
WORKAROUND: Cancel flashing by exiting LG Update Tool. Phone should be still in SW Upgrade Mode, Remove USB Cable, wait 10 seconds, Insert USB cable again and let all drivers install for this mode. The device manager should look LIKE THIS SCREENSHOT. START AGAIN FROM STEP 6 (Read about Post-JB Issue)
Click to expand...
Click to collapse
BOOTLOOPS? STUCK AT LG LOGO? : Dont worry!!! If you were on CM and flashed JB or vice versa or your data partition is not matching with new partitions, then your phone may get BOOTLOOPS on LG Logo.
HARD-RESET to solve it (Press VolDown, Home and Power all together) You will loose data, dont worry, before starting you took BACKUP and I am sure about it. Phone should start normally. (Click for correct method of HARDRESET)
You're done!!! Phone is FLASHED!!!
12) Remove lines we added from HOSTS file mentioned above. Do it now!!! Dont complaint later that LG KDZ download links are not working. LOLZ
IMP NOTE: This is also called OFFLINE FOTA and all your Phone Settings, DATA on internal card and external card and also the installed APPLICATIONS will remain as it is. Enjoy!!
TROUBLESHOOTING, IN CASE OF ANY ISSUES: Check following workarounds.
Uninstall LG Driver, RESTART PC and then REINSTALL DRIVER before connecting phone to pc.
Run B2CAppSetup.exe and let it download and install LG Support Tool. After it opens just close it because it will not be needed later.
After Adding lines in HOSTS file, confirm if file is saved or not and then RESTART PC to see the added lines are there or not. This is to be done after first step is done.
Sometimes the downloaded file could be corrupted too. Do fresh download when your internet connection is good.
"Microsoft Security Essential" (Antivirus+Firewall) falsely recognizes "C:\shttps\http.exe" as virus (false alarm) and blocks it. Either allow it to execute or Get RID of this Antivirus.
....and try again with next procedure.

Rooting ICS ON LG OPTIMUS L9 (OLD BIN4RY METHOD) Only for ICS.
Thanks to Bin4ry who gave us this FIRST Working L9 Rooting Method.
1) Download and Flash Rootable ICS KDZ: It is known that this Root works on V10A for all L9 Models. Root works on V10C on P765. Root works on V10E on P769 (No Rom available, V10E comes from factory). Root works on V10A of P768.
At the moment Rooting does not work on higher versions of Roms, hence you will need to downgrade by flashing Rootable KDZ. Find Download Links of Rootable KDZ in this thread and please read related information carefully. This tutorial was made after testing with Indian V10C KDZ for P765.
2) Download "RootBinary.zip" (attached) and Extract to D-drive on your pc. You will find a new Folder "D:\RootBinary" and some files inside it.
3) Precautions:
___A) Select "Debugging Mode" as ON (Ticked) in Phone Settings (Developer Section)
___B) Select "Install from Unknown Sources" as ON (Ticked) in Phone Settings (Security Section)
___C) Indian version of L9 does not come with "Lookout Security Antivirus" already installed. But KDZ from other countries may have it already installed, FORCE CLOSE AND UNINSTALL it from app manager. If you cannot uninstall, at least DISABLE it. This program is known to be preventing connection and rooting of device.
4) Install Drivers "LG USB Driver (Download 4.0.4 here)"
5) Connect Phone to PC with USB in "MTP" mode, let all drivers install for detected hardware items, then in "Charge Only" Mode, let all drivers install, then in "PTP" mode and let all drivers install, LASTLY connect in "LG SOFTWARE" Mode and let all drivers install. (confirmed by this user too)
(Installing drivers in MTP, PTP and Charge Only is necessary, it does not take too much time. Just do it. It may save your time, as your rooting process will not stop for any unknown reason at any point)
6) Keep phone in "LG SOFTWARE" Mode and wait until it is connected. Now at this moment Device Manager should show 3 entries like this. If not, flashing will not work.
7) Now Open "Command Prompt" on pc with "RUN AS ADMINISTRATOR" option. (Type cmd in startmenu and when "command prompt" appears, right click on it and run it as Administrator)
8) Type "D:" and Press Enter key. And then type "CD \RootBinary" at Command Prompt and enter in directory, to show "D:\RootBinary>" in command prompt where your root files are present.
9) This is optional but its good to check if your Phone is connected to PC or not. Always better to confirm it. Type following command in command prompt box "stuff\adb devices" (all lower case) and press enter. Now Command Prompt should show the line showing the Device ID of connected device. (see image)
10) Now type and enter main rooting command "RUNME" (executes RunMe.bat) and then Select 1 for Normal Mode Rooting. Now look at Phone you will be asked if you want to RESTORE DATA, press "RESTORE MY DATA" button on Phone.
11) The Phone will reboot twice automatically and that is normal, press key on computer when prompted
12) YOU WILL SEE A LINE SAYING YOUR PHONE IS ROOTED. Go and check in phone app list, if icon of "SuperSU" is present or not. If yes you are ROOTED (Now install CWM in next step).
SIMPLE TEST: When you install and open (run) AdAway, then SuperSU will stop you and ask for permission to open. VOILA!!! Thats the sign of rooted android. Its done! Enjoy
13) IMPORTANT: Above only plain rooting and does not install CWM (ClockWorkMod). Now you need to install CWM Recovery Installer by Artas182x to use CWM.
ALL SCREENSHOTS ADDED.... Please check all carefully.
PROBLEM? If Bin4ry's rooting file is not working then, you can try same by replacing with Zanakorus33's Batch file, instead of "RunMe.bat" file by Bin4ry. Thanks to Zanakorus33 and Mingkee.
FAQ: Frequently Asked Questions
-------------------------------------------
Q) Even after fresh flashing or when any experiment goes bad, you may see following DEAD ANDROID with Red Triangle and exclamation mark over its body. What to do?
Workaround A) You may think, you have just killed it, but HEY, Wait, Relax. Even I got this issue when I flashed Prada Apk for CWM and then reflashed.
FORCE SWITCH OFF: First press Power Button for 10 seconds, phone will turn off, like laptops turn off with same trick. Then restart phone and see if it starts normally. If no then you need to do hard reset as mentioned below.
HARD RESET: Remove the Battery and insert it after few seconds. And now do the 3 button HARD RESET. First press VOLUMEDOWN and HOMEbutton. Then Press Power button only for 3 seconds and release power button but dont release VolDown and Home button and KEEP BOTH PRESSING until you see a Bigger Green Standing Android and circulating Molecular structure above it. DONE! Your Android should boot now and will be back in action. ALL DATA AND APPS WILL BE WIPED, BUT HEY IT GETS ITS LIFE BACK and LIFE'S GOOD.
Workaround B) You might have issue with bootloader or CWM installation error, JUST FLASH KDZ AFRESH and you will again see above screen after finishing, Just Repeat Workaround A, hard-reset it immediately. (I had to do this at least thrice, and everytime it came back ) Thats why they call it, LG DEVICES ARE UNBRICKABLE. A completely ignored feature which wins above all.
-------------------------------------------
Q) What is KDZ? Sorry I am first time on XDA with new LG Phone.
A) Welcome to XDA, Like we install Windows XP or 7 on pc, every phone needs Operating System too to function. Phones also need this OS and its Drivers to be installed and functioning. The OS files here are generally called "FIRMWARE" or "ROM" files. The company LG bundles whole OS, Drivers and other supporting files and applications, into one single huge file and they gave it a file-extension name as "KDZ". The regular updates of OS are also released by manufacturers either via download or directly in device via 3G or WiFi which is also called FOTA (Firmware Over The Air). Here in this thread we are talking about flashing (clean install) of the KDZ on phone, which should actually be done by LG Service Centres only and not us. But well these days everyone is doing that with the help of helpful tips and apps given by experts on XDA. Hope some things are clear here.
Size of KDZ file: Generally KDZ files for LG L9 are around 480+MB to 600MB for ICS version. For Optimus 2x the KDZ file is around 300MB (GB) to 600MB (ICS). Hope this helps too.
-------------------------------------------
Q) Well, I could successfully Root my phone, but how to install CWM?
A) Working CWM 6.x by Artas182x is here. Read instructions carefully.
-------------------------------------------
Q) After installing CWM by Artas182x, how to go Recovery Mode (in CWM menu)? Could not go by pressing Power button while pressing VolumeDown. (Why LEDS on phone blink rapidly while rebooting phone?)
A) That method is wrong for CWM. The correct method is Switch On phone with single power button and release it. When LG logo appears in a moment LEDS start blinking, quickly press and release VolDown button, you will be now in CWM menu.
-------------------------------------------
Q) After Rooting on V10C, can I update to latest ROM, keeping device ROOTed?
A) Not directly by upgrading via OTA (Air). BUT YES at some extent you can do it for some models. There is a thread by me with Collection of Rooted CWM Backups for various models. Read thread carefully for details. While writing this (on 24-Feb) I am on Rooted P765V10G due to the CWM Backup sent by another user DarkFable.
-------------------------------------------
Q) How to start L9 phone in SW Upgrade Mode and connect to PC?
A) Connect USB cable to PC but do not connect to Phone. If phone is on, Switch it OFF. While Pressing VolumeUP button and insert USB cable into phone and keep pressing the button, let windows load any drivers (if required), wait until it finishes. Phone will show SW Upgrade Mode screen (SEE IMAGE) and you can release the button.
-------------------------------------------
Q) I am not able to Root my P765/P768/P769/P760? What could be wrong?
A) Everything to ROOT L9 is available in this thread, read carefully and do as instructed.
This tutorial was made after successful and easy flashing of India V10C Rom and Rooting P765 on it. You can find download link from second post above for matching V10A for your variant. You can download and flash roms released for other countries too, as most of them will have English (US) as a common language.
A user could Root P760V10A and using Voodoo, updated to [V10E on OTA] and Restored Root with V10E. Will not work with offline flash method.
-------------------------------------------
Q) Can we OverClock L9?
A) I have not tried but yes, someone already did OVERCLOCKED L9 to 1.3GHz here. http://forum.xda-developers.com/showthread.php?p=34192656
-------------------------------------------
Q) Where can I find official KDZ ROM for flashing for my device?
A) You can visit my OFFICIAL ROM LINKER page , enter your IMEI and find your own latest ROM available to Download. Works for any LG Android SmartPhone. Or you can visit this page for old Official KDZ for any device any country.

Q) What if I HARDBRICK my phone and it never recover back?
A) According to this post, one of our L9 expert artas182x who says, "For now our L9 is unbrickable, because we haven't got access to recovery.img and boot.img and we can try many methods to port CM9 or CM10 without hard brick." And that is fact, so lets relax at the moment.
-------------------------------------------
Q) How to extract bootloader (boot.img) and recovery (recovery.img )_from any phone or KDZ?
A) There is very good procedure explained here by AngryWolf80. Please read and click THANKS button for him.
EDIT: Worked perfect on PC with ADB SHELL. (Hint: Give "su" command first)
-------------------------------------------
Q) How to Run As Administrator? Where we find this command?
A) Please Google it. (trust me someone asked me this recently, well good news, not on xda )
-------------------------------------------
Q) How to start Service Menu (Hidden Menu) on L9?
A) To use Service Menu or Hidden Menu type 3845#*760# and call you will get Service Menu. This example is for 760, but you can enter 765 for P765 and so on. Dont actually mess with options as these are serious commands used by qualified service center engineers. Some options are easy to understand but most are not. So be careful and don't say I did not warn you if you lose network permanently.
-------------------------------------------
Q) How to use DLNA of L9? (How to use L9 as Media Storage Device)?
A) I created one more Tutorial for DLNA connection of L9, here.

Hope this helps.

May be its stopping saying "Permission Denied Are you root?" I am not sure. But please also see step 4 (newly added).
Firstly, as we both have P765, it should work with INDIA V10c link. But as you say its not working, I may help if you clearly mention where it fails with what message? and with what circumstances? May be you are missing some link or driver issue or small server issue. We will come to know only if you give clear picture, may be with screenshot.
I will also recommend you to try ROOTing on V10b and V10a of INDONESIA/INDIA, if possible. Well at the moment we all are still at experiment level. So Good Luck.
please help!
have an lg p769, 10e. was rooted, tried the recovery image/ cyanomod apk posted in the other thread. (for the prada?)
**SECURITY ERROR**
phone will not get past first splash screen (LG, SECURITY ERROR)
cmahendra,
followed all your steps in this guide (GREAT job, by the way!) but when kdz is supposed to say: 'check your internet line' 'continue' or 'cancel' it only says: 'check your internet line' 'restart' or 'cancel'
selecting cancel stops the process. selecting restart only shows the message again.
windows selector is on. small http is installed and adjusted (9002). edit hosts short cut is edited. kdz and shttp in root directory. s/w upgrade screen able to show on phone. lg s/w upgrade tool able to recognize phone and current software installed on it (when shttp is off).
please please please help! i really love this phone's potential and REALLY don't want to pay to get a new one.

same here im having the utmost issues getting my phone back on can you help us dude?
ok one thing that was missing after all the hassle was the automatic offline procedure which you must run with command prompt after setting the hosts up and turing on the server as well you must start the windows enabler as a administrator attached is the missing file just rename it without the .txt to use it in command prompt

alright, alienn, refresh my memory real quick... how do i rename the txt file? F2/menu rename/properties all just keep it as .txt. 'save as...' doesn't seem to do it, either. dragging it into cmd just gives up a 'will not work, blah blah' result.
and is this anything like the other automatic offline post I saw?
thanks either way, though

The vbs file does whole process automatically, but some people had issues with path and other things. This guide is complete manual and transparent process with no chance of mistakes.
PS: please delete my whole huge OP you have quoted in your post, which was not necessary. I see no point in repeating whole thing when your point is easily understandable.

This is not automated offline fix via visual basic script. This is pure and transparent manual step by step guide. Hope u could use it.
Once you did it and understood, next time you only need to run http.exe and start flashing. No other step required.

WOW L9 Friends.
Expect some good news in next few days. I somehow managed to get Admins to pay attention for L9 subforum through a moderator we know from O2X forums in PM. Posting in that subforum request thread did not help us.
But now hopefully very soon L9 subforum will start. I may not be sure but I am positive about it.

Would it be possible you think to have something with your same model dump the system root and you use what you need to copy over misconfigurations? I have the same model but would need to know exactly it is you would need duplicated

If your LG phone have IMEI (lolz ), you can try my ROM LINKER PAGE and no matter whatever country it was sold, you will get exact latest UnRooted Official Rom. To clean all the previous workaround or leftover signature, you should do HARD RESET either before or after flashing.
they didnt have mine thats why im having so much trouble

Send your imei in PM , it's strange why you don't get your Rom with that. And yes it's not mandatory that you should flash Rom.from your country only. You are from USA then you can flash almost any Rom as US English is common in all.

I have a bit of a problem right now with my old LG P760.
So yesterday I was trying to install a custom rom on my old phone, so that I could update it to 4.4 KitKat. (It was running on the official OTA update 4.1.2 Jelly Bean) But I forgot what my password was so I couldn't unlock the phone. (It was rooted by the way) Then I hard reseted it so that i could go through the setup wizard and after that install the custom rom. Only I forgot i deleted the system keyboard. So when I was trying to type in the wifi password the keyboard wouldn't show up. And I cannot skip the setup wizard so that I could activate USB debugging. If anyone has a solution to this problem, then it would really help my out here. Thanks!
Hey. Go to https://www.lg.com/ru/support/support-mobile/lg-P765 download USB DRIVER and LG MOBILE SUPPORT TOOL in the Software & Firmware section, then install (on Windows 7), then turn off the phone, press the volume up button and hold it, connect it to the computer, if everything is normal, the phone will switch to s / w mode, LG MOBILE SUPPORT TOOL will detect the phone and in the additional section select recovery after unsuccessful update and wait. Perhaps some data will be deleted.
Actually I somehow fixed it by not setting up my wifi, and then I was able to skip the setup wizard. Then I installed a few necessary APK files (including Gboard) but then I started going crazy trying to unlock the bootloader and flashing a custom recovery. After messing too much with the root app flashify, I just about broke down after this mistake: I got the LG Security Error. So a few days after that I wanted to install the LG mobile support tool (I did not click on you're link yet btw), but it wouldn't install on my Asus laptop running Windows 10. So the next thing I'm gonna do is try you're link, and if that doesn't install, I'm simply running out of options. But anyway thank's for you're help!
