Can't remove tri point 000 screws in iPhone with ifixit bit.

"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."

"The problem is that most of the drivers are too pointy, and the screws arw nowhere near as deep. If you take some fine sand paper and sand or file the tip flat so that when you look at the end of the bit under a light you’ll see a “Y” shape that’s rather thick or “bold”, instead of a sharp point, or a very thin “Y” shape that’s not well defined.

Remember though, don’t keep trying bits that don’t grab right away. every attempt that fails to turn it will take a little more metal from the screw.

UPDATE: after finally finding a proper Y000 driver at a local electronics store I was able to complete a repair on an Apple Watch series 3. While I did have some success filing down a cheap tri-wing driver until it fit the screws, there was one screw that it wouldn't loosen. The bottom line is this:

Get a proper Y000 driver, don't use Y00 as someone suggested. Don't use hot glue. Rubber bands do sometimes work but they won't in this case because the screw is too small and the driver will poke right through the rubber band with the application of any pressure.This is one of those things that requires a little bit of money to be spent because the tool manufacturing process and material used both need to be top-notch.If the tool is advertised as one that's made for Apple products then it's probably going to work fine provided it's from a reputable tool maker.If you keep trying to drive a Y000 screw with a tool that doesn't grab well you'll strip the top of the screw and then you'll need to find a way to make a straight groove in the top which will allow you to remove the screw with a tiny slotted driver (flat head). There are a ton of problems that can arise as a result of this. Metal flakes can get lodged in between surface-mount components and do more damage to the device. Also you could slip and cause more damage. Etc.

The best way is almost always the originally intended way. (Except when the originally intended way is to pay Apple to fix it.) Good luck."

I've been buying these for years. They're crappy Chinese drivers. But their 00 and work ever single time for millions of passes. Eventually they break. The top, the bottom. But they work great for at least a year or two. Now they've become more and more difficult to find, and I'm starting to think about what I should get next. Why does iFixit discontinue good equipment????

Just a suggestion: it may not be the bit but the driver. I have found using a driver with a larger diameter handle allows you to exert more torque on the screw and downward force to keep it from twisting out. The driver handle in the old 26 bit set was excellent for this but I can't find anymore. This is also a very good driver:

I had the same problem and I asked for refund. Then I bought Wiha Y000. IT IT AMAZING!

I got three out with a blue 00 philips with just an ounce of torture,the home button screw was not budging and the ones on the shield I recommend replacing with a Philips if you do actually get them out.I learned that this drive first came about with Nintendo items and so I imagine if you order them for a Nintendo quality kit you will have solved the issue.
