The charging port assembly is removed in step 7. Simply follow the guide to step 7, replace the charging port assembly, then reassemble the phone.

For best safety the phone battery needs to only be under 25%. The phone will say 0% and shut off, but the battery is not fully discharged. Completely discharging lithium ion batteries has the possibility to do serious damage to the chemistry, reducing its lifespan or capacity, or causing it to refuse to charge again.

I've edited the guide to mention this as well, but isopropyl alcohol (ideally high percentage) will soften most phone adhesive, making it significantly easier to remove.

Both are “correct” as these are likely slightly different revisions of the same device. There seems to be a version of the device that comes with USB-C as well.

If you open yours up and find a battery without the metal frame, be sure to use care when removing the battery. Isopropyl alcohol helps soften the adhesive.

They can be purchased as two seperate pieces, but I highly recommend buying the complete assembly instead of fiddling with glueing them together.

Likely a damaged LCD or LCD cable.

Look for a model number on the back of your tablet and search ebay, MobileSentrix, etc for a digitizer. The correct adhesive tape to use is Tesa 61395, sold by iFixit and elsewhere.

Go back to step 10 and make sure the display cable is firmly seated

I bought the display adhesive strips from iFixit but I cannot get the display assembly to adhere to them. How do I do this?

Youtube video linked shows removal of earpiece speaker, which is totally unnecessary for this procedure. Wound up breaking the speaker while trying to remove it.

Oh this is definitely not something you do every time. Spraying canned air into the vents should suffice. This is a deep clean tutorial. I do this about once a year (may vary more or less depending where you live)
