According to Yojiatech website I thought the latest firmware is September 140410_0925?
So if I get that "upgrade file is mismatch" message then its a clone? Is that the only way to tell if the box is a clone or not?
I thought updating the firmware automatically resets to factory settings after the update?
The clue is in the numbers. 140410 is the date (10th April 2014).
If you have the box that the V5s came in, it might have a QR code (square barcode) on it. If you scan it with a smart phone it will take you to skybox.cc (original firmware), or hddvbsw.com (clone firmware). I'm still not sure about whether firmware from yojiatech is for clone boxes or not. I keep meaning to try it on my clone & original boxes.
Also, when your box boots, do you see skybox.cc in the bottom right corner of the boot screen?
If you go to menu > tools > information, you can see what your current firmware is.
As I said above, if your current firmware has the option in the menu for "keeping DBS & settings", then it will retain your current settings.
henrikno7...what is your current firmware, & what problems are you having?
