I too, get the AICP OTA update crashing problem. This was happening in the 6.0 version as well, and is still happening in the 7.0.
Another side-effect is the disappearing microSD card has come back again after updating to 7.0.
Here's the funny thing: when the microSD card disappears, the AICP OTA works! In 6.0, OTA crashed very often, but every once in a while, it would actually work (unable to recreate the conditions to make it work, seems to be random). That's how I managed to keep doing OTA updates.
I'm going to do a clean install of 7.0 this time, see if it helps. I did an OTA from 6.0 to 7.0, so there might have been issues with the upgrade.
