It's pretty stupid, that most Pixel dissasembly videos don't talk about the two different seams.
On the first one I've opened it was very hard, because I've applied not enough heat before and maybe also because it was the seam that losses together with the screen bracket, which seems harder to open in one step.
The 2nd one came off pretty easy after first enough heat was applied and then I had to searately remove the screen bracket to get out the mainboard - BUT then only the top seam opened and the screen bracket itself remained in the case. So how to fix that? Is there another seal available for it, just add small amount of B-7000 or what is the best way to seal it well?
