You Phone's Flash ID Not Supported By Volcano Tool !! After Format With Merapi Hang On Logo Then Write Your Backup And Try to Remove Pattern Lock By ADB Root !! You Don't Make Backup Befor Format Then Find Stock Rom

If ADB Not Turned on Then Put Phone Into Factory Mode Then Root After Unlock Phone !!! If Factory Mode Not Available Try META Mode Pattern Remove
