- 3) Rename the extracted archive to "EP201_768_SDUPDATE" (without the " ") and upload it to a MicroSD card
- 4) Insert the MicroSD card in your tablet and use this button combination to Power ON and go to recovery --> Start the tablet by pressing Volume Down and POWER togheter for 5 seconds ,a message will inform you that you have 5 seconds to enter the recovery,press Volume UP before the 5 seconds expire.
