Tutorial :

1. Download Android 5.1 Lollipop ROM from link below :
The ROM File size is 328 MB, so I split the file into 3 parts :
ROM Part 1 : http://goo.gl/DkwIrl
ROM Part 2 : http://goo.gl/n6NZfC
ROM Part 3 : http://goo.gl/R10Pv2
To join 3 parts files above into 1 file just use WINRAR, then extract the files into ZIP format.
If any problem with the ROM, maybe because the ROM have corrupted during the download process, you can try to re-download the ROM.

2. Install the ROM Manager on your device. Get it from Google Play Store, then install the clockwork mod recovery. You also can use ROM Installer application from JRummy Apps Inc.(Get it from Google Play Store).

3. Connect your devices to your PC employing the USB information cable. Copy the “ROM.zip” file you downloaded to the SD memory card.

4. Restart your device in the recovery mode using ROM Manager. As soon as in Recovery Mode, go to ROM Manager and select backup/restore to back-up your information.

5. From the Recovery Menu do a total data erase (including Delvik Cache). When completed, go back to Recovery Principal Menu and choose Flash ROM from SD Card. Navigate the location you copied the ”ROM.zip” file and follow the directions for installing Android 5.1 Lollipop on your devices. As soon as the installation is over, just reboot your device, and here you go, you’ve just upgraded it to the new Android 5.1 Lollipop.The first boot will take some times .
