READ THIS WHOLE POST BEFORE ATTEMPTING ANYTHING. I WILL NOT BE HELD RESPONSIBLE FOR ANY DAMAGES OR MISHAPS! YOU'VE BEEN WARNED. WHEN IT SAYS YOU NEED SOMETHING, YOU NEED IT. IT IS NOT OPTIONAL FLASHING STOCK RECOVERY VIA FASTBOOT STEPS ARE BELOW THE STEPS FOR FLASHING STOCK ROM ATTENTION TO THOSE HAVING ISSUES: After flashing back to v6 if you can't receive OTA updates please download and flash stock recovery from here: Stock Recovery(Ally) Then do a hard reset (Vol-Down+Home+End). Sign in with google, then do *#*#CHECKIN#*#* Hello everyone, just thought i would post this how-to thread since my post in the Ally V9 SW Update is buried. Flash Stock LG Rom. Disclaimer: I put my phone on the line to try this and it worked fine for me doing the steps i detailed below. It is possible to brick your phone doing this so be careful. I am not responsible if you end up with a ~$500 paper weight. You have been warned. If you are still with me, here are the steps: MUST HAVE LG MOBILE UPDATER INSTALLED AND USB DEBUGGING ENABLED! To enable USB Debugging: Settings>Applications>Enable USB Debugging Download LG MOBILE UPDATE TOOL W/ ALLY DRIVERS (Only if you do not have either one of these installed) UPDATE: If you are having issues please download these drivers: LGAndroidDriver, install and then follow the instructions. Update 9/08/10: It has recently come to my attention that if you have used roms and custom recovery and you try to restore to stock you get stuck at the A N D R O I D screen. The Fix: Boot into recovery and wipe data+cache and dalvik cache then restore to stock again. Update 11/04/10: User Mael has recently pointed out to me that he is using windows 7 ultimate (i'm running home premium) and he was having a problem with the files he downloaded being blocked my win7's security settings. Right click on the cab file and if it displays it is blocked because it came from another PC, unblock it. do this for the vs740 folder as well. make sure sub folders and files are included. Thanks to Mael for this solution. Step 1: If you haven't done so already download VS740.zip and save to the root of your C:\ drive. Step 2: Open the zip file, and drag the folder to the root of your C:\ drive Step 3: Open this folder that you have just downloaded. Step 4: Rename the cab file to VS740ZV6_01.cab (If you do not see the .cab extension DO NOT add it. Also You may not have to rename it if you downloaded it as the same name.) Step 5: Extract the zip file's contents to this folder and connect USB cable to phone. Step 6: Run KP500-Utils-En.exe in compatibility mode for Windows XP SP2 and as an Administrator. (Only if you are not running windows xp) Step 7: Choose option J. Step 8: Type VS740 when it prompts for phone model number. Press Enter. Step 9: Type VS740ZV6_01.cab when asked for the cab file. Press Enter. (You do not have to tell it what directory the cab file is in) Step 10: Type VS740ZV6_01 when prompted for the version. Press Enter. Step 11: It should now tell you it is loading and the familiar lg manual updater screen will appear with a log window below and start reading information from your phone and then it will flash it. If the firewall says its trying to access the web allow it. Your phone will switch to a screen that displays the LG and Verizon Wireless logo and say: DOWNLOADING! DO NOT UNPLUG! It will flash the update to your phone and takes around 20 minutes to complete. Once complete it will boot up and show the word android on the screen. It looked like it hung at that screen but it didn't it just took a while. Around 10 minutes. Once this is complete you may unplug your phone from USB. UPDATE!: After you finish flashing stock rom, Power off and press and hold Vol Down+Home+End and when it loads back up open the dialer and dial *#*#CHECKIN#*#* to force your phone into downloading the v8 update. and then VZB Update Congratulations! If successful you now have the stock LG Rom. Enjoy! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Got the stock rom running, but need stock recovery to get OTA updates?
