Successfully completed this guide. I have touch id home button, so transferred it from the old broken front assembly to the new one successfully. All working as expected again.
Cool, thanks guys. I used the guide successfully to upgrade the RAM on my HP 15-r033na Notebook. It would have taken ages without your help! A really tough way to reach the memory.
I wonder if the second DIMM slot is usable. The specs I've found says this board only takes one card, so maybe the second is disconnected.
