Good day mate,This is how I solve the problem of the new bootloader: First,loader the july bootloader(edit the file to et9x00 and press ch down to flash),after that load any image or your back up.Before loading new image or your back up,you must delete a file "boot.bin" from the image if not it will not go. After all these my receiver is back to life. Even though et9x00 is still showing
