Been a year with Xperia Arc, is time to unlock booatloader and install CyanogenMod custom rom, the latest CyanogenMod 9 (based on Android 4.x Ice Cream Sandwich).

Thanks to Free Xperia Team from XDA Developers forum that putting hardwork and keep rolling out updates to make sure CyanogenMod works good on Xperia handset. Below are brief explanation on steps to install CyanogenMod 9 on Sony Ericsson Xperia Arc (LT15i).

  • CM 9.0 is still in progress, some function are not working yet, refer HERE

  • Preparation and Steps:

      i) Speed reading through these sites:

      ii) Downloads (These are whatever i downloaded to make it done)

      iii) Sequences in brief (Detail steps refer to the links attached)

  • Install Android SDK by following this site: Howto: Install the Android SDK

  • For application downloads: Freeware Lovers: alternative Android apps download Site
  • Minor Problems:

    Have met few small problems during progress, i just Google-ed out solutions and replaced some file that can be found (which included on “Downloads” section above). Problems such as:

  • During SDK installation, i left out Google USB Driver install, therefore met problems in next stages.

  • Since i have trouble on SDK, i refer to this site too: What Is ADB And How To Install It With Android SDK

  • Replaced C:\android-sdk-windows\extras\google driver with usb_driver

  • when click on menu button to connect via pc, it asked to instal Android adb Interface
    adb Driver for xperia Arc. i downloaded this and direct windows to the folder and install

  • Fastboot not working in my terminal (cmd mode), downloaded fastboot_with_Android_USB_file.rar and copy all (fastboot.exe, AdbWinApi.dll and AdbWinUsbApi.dll) in C:\android-sdk-windows\tools

  • img boot, need to type full HDD address in terminal. In my case, my boot.img is in D:\Xperia Arc Flash\CM 9, so i typed this in terminal: fastboot -i 0xfce flash boot D:\Xperia Arc Flash\CM 9\boot.img

  • Boot device into bootloader: in arc, Press & hold the Menu button while connecting the Sony Ericsson Xperia Arc to the computer, it will display Blue color on LED Notification light

  • ClockworkMod Recovery: typed “fastboot -i 0xfce reboot“, i pressed side Volume Rocker after the “Free Xperia Project” screen, so it doesn’t boot in ClockworkMod Recovery. Should pressed side Volume Rocker before or during the “Free Xperia Project” screen
