I also had this problem with an iphone 7 plus that came in and I had 3 different drivers I bought from 3 different places and also the free cheap one that came with the new screen replacement.
I ended up having to take a straight screwdriver I got in one of my iphone 6 replacement screen kits and taking a file to it, looking under a scope and an hour and a half of tinkering with it to get them all out to get my customers phone completed.
Since then, I have returned 2 of the Y000 to amazon and tried 2 other suppliers there, went to ebay and bought one from the UK.
This was recently, so they have not came in yet but will keep you posted on which one works best. But with 4 different tips from 4 different places and still no luck finding a good one, I think its gonna be hit and miss with finding a good one.
BUT...the file and cheap straight one got me past the immediate need, but did have to use magnification to get it just right.
