Ok you need to download ss76C update file
then enter flash mode as normal the follow these steps
1 flash genuine image of choice
2 after image has flashed (dont hit reboot) open 2nd browser window with dm i-p address
3 flash the 76c file . reboot box and good to go dont give your box a chance to report no CA errror , just put the 76c in before you do anythin with the box
