Installation process

IMPORTANT: you need recovery by yannou90 with ext support to use this rom, please follow step 3 from this tutorial (or 1 to 3 if you have not rooted your phone yet).

1. Backup your existing ROM first (steps a to e):
a. Reboot into Recovery menu.
b. Select “Backup and Restore”
c. Select the “Backup” option (don’t remember the exact text)
d. When done, select the Reboot System option
e Connect phone to PC using data cable and copy the folder clockworkmod from the sdcard to somewhere on your PC in case its needed for restoring later.

2. Prepare your SD card, using MiniTool Partition Wizard Home Edition,
a. move all existing data on the SD Card to your PC and delete all files from it. RESIZE your existing FAT32 partition to a size where your unallocated space is at least 1GB but not more than 2GB.
b. Create a new ext4 Primary partition using all the unallocated space.
c. Apply changes

[I’ve written RESIZE in CAPS because when I tried deleting and creating the FAT32 and ext4, my phone didn’t recognize the formatting as valid. So I allowed the phone to reformat the sd card and then did it using resize FAT32 instead]

3.Download the latest version of JaggyRom from here.    [GoogleApps included]

  • Copy the latest version of JaggyROM.zip to the sdcard root. Don’t place in any folder. Rename it to update.zip
  •  Select “Wipe data/factory reset” option. Note that this option is present in the Recovery menu and is not the “Factory Reset” option available outside of Recovery menu. \
  •  Select “Install zip from SD Card” and “Apply /sdcard/update.zip” and confirm.
  • Once done, select “reboot system”

First boot takes a little longer than expected so be patient and don’t try to reset the device. The JaggyROM boot screen will show up: amuse yourself with the animation and refrain from touching the device Once booted up, let it sit a while longer to stabilize before unlocking the screen.And Enjoy !
