• Remove any cables from your phone.
• Switch the power OFF !
• Take out battery and taste it with your tongue. 
• ( This is not a joke! Your experience will tell you, the status of your battery. That's it. )
• Copy the dload folder including update.app to a formatted SD card.
• Press and hold volume up and down keys, and then the power button.
• When the boot screen appears, release the power button : but not the volume keys.(Vol+ & Vol-)
• You can release them when you see the firmware upgrade interface. 
• Leave the phone by itself.
• The upgrade process may take up to three minutes.
• Just sit back and wait.
• That's all. Good luck.
