Just a thought, maybe it's the Estar image that's causing the ca error, I don't know for sure, but it might be worth a try to do what I did on my clone when changing from sim2 to A8p. you could try downloading openPLi again, not the Estar version, but go to the site, and download an original image from there, install it, don't reboot, then load original ssl84 bootloader to the box, then without rebooting, put the A8p sim in, then reboot. As I say, I don't know for certain if this will help in your situation, and certainly can't guarantee it'll work, but it did for me. I hope I'm not giving you wrong info. All I know is, I can now load original images and drivers etc, which is great. I have ended up going onto original newnigma2 image, I couldn't get mytube to work on openpli, unless I'm doing something wrong..
