  • Using a USB data cable connect your Galaxy S Advance to PC, enable mass storage mode and transfer both the downloaded files on your phone’s SD card.

  • Now you need to enter your phone into CWM recovery mode. Recovery mode can be entered by pressing & holding Volume up + Home button (middle button) + Power button together till you land into recovery.
  • Touch won’t work in recovery mode. So use Volume keys for navigating up and down and use the Home button for selection.
  • Before flashing any custom ROM it is necessary to take a Nandroid backup of your current ROM.
  • Then you need to wipe the data/cache present on your device.
  • For that navigate to the ‘wipe data/factory reset’ option and on the next screen select ‘wipe cache partition’ option.
  • This will clear all the data & caches from your phone’s internal memory respectively.
  • Then navigate to the Advanced option located on the recovery mode itself.
  • Select the Reboot Recovery option on the next page.
  • Wait until you boot again into recovery.
  • Let’s flash the Android 5.1.1 Lollipop based CM 12.1 ROM now.
  • Go to the ‘install zip from SD card’ option using Volume keys & select it using the Home button.
  • Then on the next screen select ‘choose zip from SD card’ option.
  • As soon as you select this option, it will show all the data present on your external SD card.
  • Just search for the CM 12.1 ROM which you’ve copied earlier and select it.
  • On the next page select the ‘Yes’ option to start the actual Android 5.1.1 Lollipop flashing process. It will take few minutes to complete successfully.
  • After completing the process again select the ‘wipe data/factory reset’ option and ‘wipe cache partition’ option to clear all your phone’s data & cache. This step is essential to solve the boot loop issue.
  • Similarly, flash the Google Apps (containing Google Play Store, Maps, Gmail, etc.) as you’ve flashed this Cyanogenmod 12.1 custom ROM. Just remember not to wipe data/cache after flashing it.
  • Everything completes here. Just restart your Galaxy S Advance by selecting ‘reboot system now’ option from the recovery mode. Note that this first boot will take more time to start than usual. But don’t worry after a couple of boots it’ll be normal.

    • 1. In the ROM zip file, search for the updater script file.
      2. Now edit it in notepad.
      3. Delete the first line code until the first semicolon you see.
      4. Delete the semicolon as well.
      5. Save and try to flash again.
      Hope this will help.
