Once your galaxy Y is rooted and ready with CWM recovery installed, lets move ahead to Nemesis Installation.

Process to install JellyNoid on Samsung Galaxy Y S5360: 

Connect your Mobile phone with the computer where you have saved Nemesis Custom ROM using USB Cable. Copy the downloaded file First of all you need to connect your phone to PC using USB Cable. Copy the download ROM package to your phone’s SD Card. Make sure to copy it in the root of SD card so that it is easily accessible during installation process.

  • After copying the files, safely unplug the USB cable and turn off the mobile.
  • Now press and hold the Volume Up + Home + Power key at the same time for 10 to 15 seconds in order to boot into recovery console. Once you see Samsung logo leave the buttons..
  • Once in recovery console, select ClowkWorkMode recovery.
  • Now once you are in CWM Recovery, scroll using Volume Up/Down keys and select “Wipe Data / Rest” using Home Key.

  • Confirm selecting “Yes” on the next screen
  • Now similarly select “Wipe Cache Partition” by scrolling down and confirm by selecting “Yes” on the next screen.

  • Now select ‘Advance’ option at bottom and select ‘Wipe Dalvik Cache’
  • Now back to the main CWM recovery screen and select “install from SD card” option.
  • Browse and select Nemesis Custom Rom which you copied on your SD Card in the first step.

  • Once done the setup will start. Keep patience, wait for few minutes and let the process complete.
  • Once the setup is done Go back to the main menu and select “Reboot System Now” to restart the device in the new ROM.

That’s it. At the first boot, you device may take 2 to 3 minutes to start as this is the first boot after installing new ROM. So don’t panic, wait and let it start. The installation is done now. Once it is booted, you will get 3 launcher option on the screen. Simply select the first one “Nemesis Launcher” to get to the phone’s home screen.

In case, I mean if somehow your phone gets stuck on Samsung Logo and wont boot, you can try out the process from start once again. Hopefully in second attempt the ROM will work fine. In my case, it dint hung anywhere and working fine, you can see it in the video below.

Good Luck. All comments and suggestions are welcome. Thanks.
