How To Update LG Optimus One P500 with Gingerbread 2.3.4 Firmware

Screen Captures:
Screen Shots of Gingerbread 2.3.4 LG Optimus One

Quick Pre Requisistes:

There are some quick list of pre requisites which you need to follow so as to ensure that the device doesn’t get messed up in the process of firmware update.

  • In the due course of this updation process, there is a possibility of corruption or deletion of data present in your phone. So, it’s always better to create a backup of the data which is there in your phone so that we can restore back the same if any data is lost or corrupted.

SMS Messages – Use “SMS Backup & Restore app”,
Contacts Stored in Phone Memory – Sync with the Gmail application,
Call Log – Call Log and Restore
Videos, Images, Videos & Files etc.– Copy to internal / External SD Card,
Internet & MMS Settings – Backup all the settings from “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • After this charge your phone to the minimum of 90% so as to avoid from the battery calibration issues. Higher the battery life, higher will be the chances of you experiencing the better battery backup after the firmware update.
  • Enable USB Debugging from the path “Settings > Applications > Development > USB Debugging” as shown in the below image.

USB Debugging

  • Close all the tools in your computer like Antivirus, Firewall and LG PC Suite in your computer as these tools may interrupt the process of the firmware update as the zip file needs to be transferred into the phone which should be connected in the Mass Storage Mode.

Now, let’s proceed to the next page where we will see on how to apply this update in your phone.

    Getting various error messages when it reboots in recovery mode. Latest is SD card marker not found. The try again from the recovery mode – can’t open the file (bad). Have downloaded various versions of LGOptimusONE_P500_2.3.4.zip. Once it didn’t give the bad message, but aborted on something else. Also instructions here are not clear – the terminal with adb shell?

    hi people.. my lg optimus 1 p500 has gingerbread 2.3 v20b…is there any way i can get the latest version or a later one??????

  14. baz

    April 13, 2012 at 3:51 am

    This is the correct way to install a Rom to make it work, first you have to have v20? Installed and phone rooted make back up, i used Rom Manager get it from market really easy to use. When you have done all this follow these instructions exactly.

    Reboot Into Recovery and wipe Cache
    Then Wipe/Data/factory Reset
    And finally go to mounts and Storage-> Format System
    Now come back and Say Install Zip from SDCARD
    Choose the Zip
    IT will do the update and say Process Complete
    Then go back to Reboot Your Phone

    this is the correct way to get zipped versions of 2.3.4 or 2.3.7 working

    anyone who cant get phone working again you will have to reinstall the original firmware using, pc usb lead and phone + KDZ updater software, i really wanted a flash of 2.3.4 to use KDZ but none around. i dont think all phones can be updated because of the phone shop who sold you the phone like carphone warehouse they have locked codes built in that you cant get rid of? i can only put v20e or v20b on my lgp500 none of the others work dont know why.
