Instructions

Now, before you learn how to upgrade your phone the right way, take care of the following: if you decide to root the device after you’ve updated it, the device’s warranty will be lost, so you will have to retrieve it by either upgrading the phone to Android 4.3 JB or by applying stock Android firmware.

  1. Now that you know all of this, you can go ahead and update your phone to the new ROM with the help of the following steps.
  2. Leave the Glance S4 file unzipped after you’ve saved it on your PC’s desktop, then plug the phone to the notebook. After that, make sure to move the file from the laptop to the SD card root of the Galaxy S3 i9300.
  3. After you are done with the said transfer, you can disconnect the devices from one another and then power the smartphone off. These actions are needed for the next step which tells you this: enter the handset in Recovery, then opt for Factory Reset/Wipe Data and then for Wipe Cache Partition.
  4. Once these data wiping actions have been performed, time to do the following: select Advance, opt for Wipe Dalvik Cache and then go back to your phone’s Recovery Menu to opt for Install zip from SD card.
  5. Next move: select Choose zip from SD card, go to the update file and flash it by choosing it. After you witness the flashing of the Glance custom ROM, you have to restart the Galaxy S3 i9300. The smartphone is now upgraded. But, if it isn’t and your handset is stuck in a boot loop instead, we recommend you the following solution: go back to your phone’s Recovery Menu, opt for Factory Reset/Wipe Data, choose Wipe Cache Partition and restart the device.
