How to remove pentalobe screws without correct screwdriver?

'10 sec solution:'

1) X-acto blade

2) stab it on hard surface (choose wisely)

3) Stab again if not sized perfectly to fit inside

4) it should work

5) goodluck

I took the smallest flat head I could find (still too big) and filed it to about a 30 degree angle and it surprisingly worked perfectly.

ive succeded in opening them with a carpet knife. the top of the blade is sharp and thin enough to open them. so you not have to pay or wait for opening ur iphone4

A flat blade screw driver that fits between any two of the 5 "lobes" may work or between one out-pointing lobe and an opposite in-pointing lobe... unless they're in there too tight. The right tool (pentalobe screwdriver) is really the right choice. It puts the force basically equally on the right places of the 5 edges.

I tried a tri-lobe (security bit area) from Menards for the tri-lobe screw for the trackpad and it was too pointed to fit. A flatter tri-lobe is needed. I might have to spend the $$ and get the right sized tools as I plan on having to do some repairs. Then again, the tri-lobe from menards was only $2 so I might just try grinding down the tip with my Dremel.

For the trackpad screw, a small flat blade did work from one outer lobe to the left or right of the opposite inner lobe (depending if loosening or tightening), but it wouldn't work on the smaller tri-lobed screws on the keyboard side of the trackpad as they were just too small for the blade.

take the end (black rubber part) of a bobby pin off and use the bobby pin ..it worked for me

used a razor blade off a back cutter. shaved just the tip. i just scrapped it slightly on the concrete. you will need a magnify glass if you have. it will help to see the screw i turned a few times. then just grabbed the head of the screw with my nails and turned it. screws are not in very tight at all. it worked easy.. 5mins. goodluck

Ive tried all the above suggestions to mixed results.

Some absolutely sucked for me but one worked great but I used a different take on it.

I took a glasses repair kit screwdriver that typically comes with new glasses or glasses wipes/spray. I had been ordering so many glasses online I had a pretty hefty stock of these tiny (though not tiny enough) drivers.

I used a typical grinder bar and swiped the little flat-headed screwdriver on it for like 30-40 strokes until it was half the size tip it started with and it works flawlessly.

I took a box cutter blade. then scratched the tip fairly vigorously on my kitchen floor (I'm sure that this would be easier on cement or whatever).Till I guessed that it was around the right width do do the job easily. It was almost like it was designed to do the job. Worked first time

I, too, used an eyeglass repair kit's flat screwdriver. Literally, two strokes against a sharpening stone at a 45 degree angle (so it makes the head narrower, not thinner). I had my iPhone open in about 2 minutes, start to finish.

THIS IS THE SIZE AND CORRECT DRIVER FOR IPHONES!!!!!!!!!!!!!!!!!!!!

Hi, usually you need to buy the specific screw driver to remove these screws. But you can also remove them by using a sharp razor blade carefully, without scratching the iphone

or use a silver slim/small nail

Triwing worked for me

I used an avocado, ice pick and a snorkel.
