Yes, there is that. By reputation, the Nexus 6p is one of the more difficult phones to open up. I wouldn't try it. What worries me is that there might be a lot of options for things to break or get weakened getting that battery out, and it still wouldn't solve the lack of updates. I haven't rejected the idea yet, but since I'm going to probably need a new phone before too long anyway, not sure it is worth the investment.
