If you boot your MTK Android (e.g Tecno, Gionee, Infinix, Opsson, Innjoo etc) phone and see Encryption Unsuccessful then encryption was interrupted and can't complete. As a result, the data on your phone is no longer accessible.
To resume using your phone, you must perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google account "

Then your /data or /SD card partitions might be corrupted . To resolve this issue, click the "Reset phone" button at the bottom of the message or boot into recovery mode and select the Wipe data / Factory reset option. You could also wipe cache partition for good measure. If the issue persists then format the SD memory card, slot it back in then reboot the phone .

* Note: If you encounter the mount /data error then readĀ http://www.hovatek.com/forum/thread-580.html

If a factory reset in recovery modeĀ fails to fix it, boot into factory mode (volume down + power button). It'll display in Chinese. Select the option which has "eMMC" in its name and wait for it to complete then reboot the phone.

Important Notice
If both a reset and firmware flash fail then it might be an emmc issue

remove the battery for 30 seconds then slot back in and boot the phone. leave it to continue. your phone will boot normally when it's done
