for reference go
here. firstly, i downloaded the insignia firmware and used a hex editor to extract the raw file from the exe. it starts the same way as the x20 fw. read the size from the header (see the ref) and extract the firmware. then delete the last part of it so the end of the file will look like the x20's fw. then use the code
here to write the two crcs and the filesize so that the x20 will accept it. NOTE: 1. Using th insignia fw you will have no sound! 2. You will have to use a procedure similar to the one described above to install the original x20 firmware, but you will have to make it look like insignia fw. 3. Be very careful! I tried to install another firmware using the same method and "bricked" my x20. It doesn't start now.
I'm NOT responsible for any damage resulted from using the method above.
