Call Log - Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Assuming that you have created a backup of all the data, it’s now time to ensure that the minimum charge left in the device is 60% so as to ensure that it doesn’t get turned off in the middle of firmware update process.
  • Up next, disable all the antivirus tools in any present in your phone as it may interrupt the process of firmware update.

So, assuming that you have followed all the instructions carefully which are mentioned above, it’s now time to head to the next page where we have summed up the instructions to apply this firmware update in your phone.

    When you publishing the tutorial, please write all the steps. Here you didn’t!
    Safe mode and Recovery mode are not the same. those who doesn’t have a recovery mode, need to install it first.

    Once the device enters in the recovery mode, you need to select
    the “install zip from sd card” > “choose zip from sd card” and then
    choose the ICS Android 4.0 Zip file which you have placed in your phone.
    It will take around 10 minutes for the whole process of update to get
    completed. Once the update process is done, the device will be landing
    up in the recovery mode. Now, select “++++ Go Back ++++” > “reboot
    system now” to reboot the phone.

    – I can’t find these on my lg gt540 optimus. only zip file “CyanogenMod-9.0.0-RC0-OPTIMUS-BETA3_Mike_Gapinski” Please help.
