The cup underneath the filter has a fitting to allow a length of rubber hose to attach, and run down to your drain pan, so as to not spill any residual oil from the filter as it's removed.

Just replaced my broken digitizer glass, and it took a full 4 hours! At least an hour of that was just picking off all the tiny bits of glass remaining around the edges after I had removed the old glass and the LCD panel, and also trying to clean off the old adhesive from the perimeter of the aluminum housing. Had a bit of trouble with the tape on the new plastic bezel, and getting some of the ribbon cables to go back in.

Bottom line, get the complete replacement part with new home button and adhesive strips already on it. That will save a ton of time and headache. Also glad I read the comments about disconnecting the battery (surprisingly not mentioned in the guide), and also about “dry fitting” the parts back on and testing them before finally fixing the new glass in place. All in all a great, helpful guide!

My wife's iPhone said "Seaching" the first time I turned it on after battery replacement. Turning it off then turning it back on got that squared away.

1.5 year old "new" battery? My original battery is 1.5 years old. The new ones I just installed say they were manufactured in January 2014.

Just replaced THREE iPhone 5 batteries over the weekend - mine, my wife's, and a co-worker's. I did mine first, and the hardest part was getting the screen to release. I figured out that all you have to do is pull up slightly on the suction cup, and a little slot will appear near the lower left corner (by the headphone jack) that you can get the spudger tool inside. After that it's cake. However I could NOT get the screen to release using the suction cup alone, and I didn't want to chance cracking the screen or ripping cables. Just a slight tug, get the spudger in there, and then you're good.

Also I did NOT remove the screen completely. Don't even try it. I was easily able to remove the battery screws and battery with my right hand while holding the screen up with my left hand. And the battery itself came out on all 3 phones, without too much trouble using just the pull tab. No prying required. Just use gentle, constant pulling pressure until you start to hear the adhesive releasing.
