Hello everyone hope is all well -:) I have a problem and I'm tearing my hair out trying to find the issue I'm having. When I flash the latest OpenPLi image for my 800seV2 with Japhar Sim I keep getting No CA error. This is what I have done so far:

Try to flash with Japhar Flasher but it won't recognise box when powered on.

Pressing mini flash up button I can reflash with image and have to use ALLSIM 88J boot loader and box hangs halfway on booting.

I can flash a Sim2 image and box boots fine with Sim2

I have removed tuner and HDD as well to eliminate any conflict but I'm about to give up as I don't know what this issue can be. Hopefully Mr Toysoft and others can help me get this box up and running again! Thanks in advance -:)
