hello, and thank you for the information. i have a question. i have installed the firmware of Z9S "RTD1296" on a X9S device "RTD1295" by mistake. the device load into the main screen and i can use the remote control to navigate but all USB ports, wifi, Bluetooth do not work so im not able to attach U disk into the device. the only data port that works is the SATA port. Can i use the information in the link provided to flash the original X9S firmware without attaching the USB disk?? Thanks
