Let’s get started with the detailed list of pre requisites and then followed by which we will be checking out on how to apply this custom ROM firmware in your Galaxy S II.

Pre Requisites:

  • In the process of installing custom ROM firmware, since the data and cache needs to be wiped, you need to ensure that you have backed up all the data present in your device manually with the help of below instructions. Don’t use KIES to back up the data as it won’t detect the S II in the custom ROM firmware.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
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

  • From the path “Settings > Applications > Development > USB debugging”, enable the USB Debugging Mode. USB Debugging option should be ticked. Ensure that the minimum battery left is 50% plus so as to ensure that the phone doesn’t get turned Off in the middle of firmware update.
  • Download “Root Checker” app from the Google PLAY Store and check whether the device is rooted or not. Also, disable / uninstall all the security suites installed in your device as it may interrupt the process of firmware update.

So assuming that you have followed all the above mentioned instructions, you can now proceed to the next page where we have summed up a detailed tutorial to install this update.

    • Pradeep Neela

  • Dunnanga

    Enormously rich in options in the installation process. Everything else clearly reflects awesome control of hardware behaviour, overclocking and etc. I had to revert back to XWLPD, why?/? because speed dial didn’t work and camera didn’t work either. God knows what else wasn’t going to work.

  • Praveen Vijayshankar

    Does WIFI, Bluetooth and Phone work properly in this ROM. Does Camera give pink spot issue?

    I have installed this from twice now but each time the SD card won’t mount. Anything I can do?

    • Pradeep Neela

      root and install the cwm

  • mmz34

    tried this ROM yesterday. reverted back to XWLPD. It was smooth and gives a lot of options during install to choose the kind of kernel,keyboard,musicplayer etc.
    Why back to XWLPD ?
    When I tried to restore data from Nandroid , phone was hung at the bootup screen for many hours. entered into recovery mode , wiped data ,cache partition, dalvik cache and rebooted .
    Next I tried the data restore using titanium. I got all my apps, active wall papers but could not get the contacts (from system restore).
    I tired Asphalt 6 and the phone re booted. Modern Combat 2 worked well.
