Upgrade Dell X51/X51V PDA to Rom A12

  1. Backup all personal data from your PDA, as this will wipe out all your data.
  2. Get a 1GB or 2GB SD card (4GB or above SDHC Card will not work), insert into a computer, right-click it and choose to format the SD card into FAT32

  1. According to your PDA model, download the zip file below and unzip your computer.
    1. X51
    2. X51V
  2. Transfer 2 files to the SD Card.
    1. X51: DiAd_K_AximX51_WM5_A12EN.nb0, DiAd_K_AximX51_WM5_A12EN_nb0.crc
    2. X51V: DiAd_K_AximX51v_WM5_A12EN.nb0, DiAd_K_AximX51v_WM5_A12EN_nb0.crc
  3. Insert an SD card to your PDA and make sure either the PDA is connected to the AC charger or has a full battery.
  4. /while holding down both the “Power” and “WiFi” buttons, press the “Reset” pin with a stylus. Continue to hold down the “Power” and “WiFi” buttons until you see the SD Image updater screen.

Here is a video demonstration of the process.

  1. Press the action key twice and wait for the Rom update to finish.

This is great; however, for some reason when I get to step 7, the ROM file is not recognized. I just have a blank screen displaying the blue bar only.. SD Image Update A10_G4. I did all steps noted. Am I missing something? The SD Card is 2GB, functions properly, and has all files required.
