I have been on 4.2.1 for the longest time with no issues. Since I was still on Gotham I decided to update. I tried to have Openelec update it's self and that was a no go. Not a big deal I downloaded the 5.0.8 image for RPi2, formatted the sd card, unzipped the img and wrote it to the card. I put the card in the pi and I got the rainbow screen. I could reformat and drop the files from 4.2.1 back on with no issues. I opened the files on the pi from samba and dropped in the update like on read to do and that didn't work. Then I installed the 5.0.8 img for the first gen pi and it works. I am sure it's a RPi2, it has a micro sd slot, 4 usb ports and the board has Raspberry Pi Model B+ V 1.2. Has anyone else experienced this issue?
