I have looked to flash my smart watch DZ09 and gain more experience on this device so I can avoid some problem caused by software next time and looking to see more feature on this device and development possibility.

After a few days of moving from sites to sites, there are few pages' sharing about how to flash DZ09 smart watch but it still makes me doubt it could be possible to brick my watch or not. Therefore from day to day, I didn't dare to flash my smart watch until I found a clear and trust tutorial. Yesterday, I found a recently update from XDA, how to read back mtk6260 firmware so now I would like to share what I have done by my own following the threat and thank to XDA for a useful extractor.


DZ09 is known as MTK6260 is a cool wearable device as well as APLUS and GT08 smart watch. These type of ROM are replaceable and close similar but not same. Therefore flashing without backing up its original firmware might lead to make device does not works functionally or brick the watch. That's why it must be backed up, your DZ09's original firmware.
