To all that has a comag sl65, yes there is a patch for this box and working, but if you go ahead with the patch you will not be able to upload or download to the box for the patch alters the serial port in such a way that if you try the box does a CRC check, so any attempt to load will not happen unless this CRC matches. You can always return to the original soft by jtag, which means opening ths box and connecting wires to it.
Now if you want the patch, look for SL35 for UCS, in it is a manual so follow it to the letter and you will get it going. While patching you will get errors but go through with all bownloads as in the manual.
On hispasat you will be able to open MEDIAPARK that you must create the privider for and tvcabo, this one does autoroll so it will go out in a few seconds but there is a way to get around this.
Good luck to you all, I have other boxes patched, but for this box we are still working on how to get a loader that works and a new patch (which is hard without inside tips) as we con not find out who wrote this software for the chess SL35.
