   GUIDE FOR FLASHING ROM IN CWM RECOVERY

   1. Boot into recovery mode. If you’re rooted, the easiest way to boot into recovery mode would be using the QuickBoot app. If not rooted, then follow the instructions below:

      • Press and hold Volume Up + Volume Down + Power buttons together to boot into bootloader/fastboot mode.
      • Press Volume Down until the Start option at the top changes to Recovery Mode, then press Power button to reboot into recovery mode.
        └ In recovery, use Volume buttons to navigate Up and Down between options and use Power button to select an option.
   2. Create a Nandroid Backup from recovery. It’s optional but very important to do, so that in case something goes wrong you can restore to current status easily. For making a Nandroid Backup, go to Backup And Restore » Backup.
   3. Perform a full clean-up of the device (This will delete all apps and their settings and game progress). For this:
      • Select Wipe data/Factory reset, then select Yes on the next screen to confirm factory reset (screenshot).
      • Select Wipe Cache Partition, then select Yes on the next screen to confirm wiping cache.
   4. First Install the ROM file:
      • Select Install zip » Choose zip from sdcard (or external sdcard, you know where your files are) » browse to the location where you saved the file and select the ROM file.
   5. Now similarly flash the Gapps file.
      └ Make sure to first flash the ROM file and then the Gapps file.
   6. Reboot your device. For this, go back to the main menu of recovery and select reboot system now.
   That’s all. Your phone will now reboot and it will take some time as it’ll be phone’s first boot after installing Android 4.4, be extremely excited for this!
   Note: In case your device gets bootloop (stuck at logo while rebooting), just do a factory reset (step 3) and you will be fine.
