have you found a solution to your bricked receiver yet?
My problem is that I cannot upgrade the Transmitter to the latest FW; it simply doesn't start the process. When I connect the USB Stick with the provided nini usb adapter and connect the power lead, then the Power light starts to flash a couple of times as it does when you connect the unit to power without any usb stick attached (no rapid blinking as in the video, I left it connected for 30 mins+). However I can see that the light comes on, on the usb stick as well but only until the sync light starts to flash slowly at the same time the power light goes solid and the USB stick lights goes out, nothing further happens. It's like that the unit searches for the Firmware on the stick but can’t see/find it. The FW aei_mwtv.bin is like that on the stick and I tried two different sticks as well already one formatted with NTFS the other With FAT and I tried FAT32 as well already. Is there another way of upgrading the transmitter for example connecting it to a laptop and start the process from there? Thanks for any help.
