Change Java Applications Background

The java feature allows us to add applications that may not exist on the original features of the phone innate. Many options that we can add / install on the phone either free or paid. Many applications that have a background of a picture or word in the image format (.png). For those bored with the look of the original background, we can replace the background with our own photographs or other images according to taste. Follow this step:

• Download the java application to your computer
  
• Open the file (.jar) using winrar
  
• Search for an image file (.png), note the name and size (resolution)
  
• Prepare a file that will be used to change background. File type must be equal to the original image file, if not please change it first, could use photoshop or other editing software you have
  
• Replace the file named according to the original file congenital application, notice the small capitalization must be exact
  
• Replace the background with a file that has been prepared by "drag & drop"
  
• Close the winrar
  
• Send the file (.jar) to mobile
  
• Install

Now you have an application with another background than the others.
Good luck.

Upgrade Sony Ericsson G502 Firmware

When I got this phone (Sony Ericsson G502), which brings the software version that is R1FA031, and it turns out this version has grown to become R1FA037, when I trying to upgrade the software via the internet with the "service update" from the phone menu, it would result latest version is always R1FA031, actually this software upgrade is only possible with a2uploader and some additional software, not through the service "service update" from Sony Ericsson phone via the Internet.

The equipment should be prepared as follows:

A2uploader download here

R1A_G502_CDF_1208_8745_FS_Customized_ID downlod here


First, extract a2uploader, but disable anti-virus at first, some anti-virus detects a2uploader as a virus, then extract G502_R1FA037_FS_HUTCH - WORLD_RED52 and G502_R1FA037_MAIN_HUTCHISON_EM_RED52, save in the same folder. Last, extract R1A_G502_CDF_1208_8745_FS_Customized_ID to tpa/preset/custom.

Before performing the upgrade, back up your phone contacts with MyPhoneExplorer or just backing up the memory card, because this upgrade process will change all your phone settings to default settings. At the time of the upgrade process should be in a state cell phone off and battery condition at least 50%, USIM card and memory card may be revoked (or not, it's no problem). Let's start...

Open a2uploader and click "add" and enter the (.rar)file that has been extracted G502_R1FA037_FS_HUTCH-WORLD_RED52 and G502_R1FA037_FS_HUTCH-G502_R1FA037_MAIN_HUTCHISON_EM_RED52 by "drag and drop" and then click the flash, press and hold down the 2 or 5 or a combination of both 2 and 5 on the phone, then connect the phone to a computer with data cable that had been prepared (phone must be in the off state), once appeared the words "will flash xxx block" in the left column a2uploader programs, emphasis should key off and wait for the flash process approximately 15-30 minutes, after appear the words "ssw file accepted elapsed: xx secs and writing Ready" indicates flashing process has finished, remove the data cable from your mobile phone but do not be turned on first. Click on "File System Tools" (right column), connect the phone to the computer with data cable, press and hold down the 2 or 5 or a combination of both 2 and 5 on the phone until appeared the words "Ready" and then open "tpa / preset / custom " and enter R1A_G502_CDF_1208_8745_FS_Customized_ID files that have been previously extracted. After the process is complete click "FS SHUTDOWN MANAGER" then pull the data cable from your mobile phone and turn on the mobile phone and wait for a while because the phone is doing a new setting.
