H9 Twin normally worked on OpenATV 6.4.
I had to reconnect the cables at the back, so I turned off the decoder with the button on the back.
After turning it on again, the decoder is standing on the Hisilicone logo, the word "boot" on the LCD, the red LED is on, then the green LED is on for a moment, and so on. I can flash the decoder and upload images through recovery.
I flashed it with different emmc recoverys, uploaded different images in slots 1-4 and nothing changed. I also had my backup image and it didn't help either. The only change is a different boot logo on the screen after flasing different emmc`s. But decoder is still in boot loop mode.
What more can I do, help me, because I'm already tired of this 
I tried 2 different PSU, different pendrives, disconnected all cables, hdd.
