I can't think of a way. To enable Autoscript you can put a ordinary Oppo chinese firmware on the player. That will enable Autoscript. After that you can install the Free jailbreak found here.My M9702 CN-065 has Autoscript disabled, any help to get it enabled and perform a nand backup? Thanks.
But then you can not do the NAND backup first which is the purpose of the NAND backup.
