I have a generic S905X tv box (Giga TV HD870 4K) working with CE 9.2.8, installed in internal memory with installtointernal command, when I boot from a USB with any newer version, it resize and check partitions and file systems ok and then reboot, shows the CE animated logo for a few seconds, reboot again and then tv box doesn’t boot from USB. I have used the gxl_p212_1g file as dtb.img. Could anyone help me?.
