You cannot upgrade from v6.x to v7.x via SD Card package. Apparently you cannot upgrade to GT1_707N0 from GT1_706N0, or GT1_705N0 and older by SD Card package. You must use the EPROM package (*.img) and if wanting to-do it via Micro-SD Card, using Amlogic Boot Card Maker. However whenever you working with the EPROM package, you are reprogramming your box from scratch. Meaning all Apps and Games downloads, installations needs to be manually redone and the configurations for them and Android main settings also customized to how you prefer it. |
