I just posted this guide. You should be able to remove the larger components using it. TCL 20 XE - screen replacement (and TCL 20 SE, TCL 30 SE, TCL 30 XE)
The best thing to close the back is buying a watch press tool and a set of dies which cost about $15. Buying a set of dies rather than just one helps to make sure you have the correct size.
Pick one of the dies that just fits the outer edge of the bezel for the front side, and pick another one that just fits the outer edge of the back casing. Arrange the seal (if any) and press slowly and firmly until you hear it click into place.
The first step in the tutorial is, "Allow your iPad's battery to fully drain before starting this repair. A charged battery may catch fire if damaged during the repair."
Ok, but that's not so simple. Is there a guide to efficiently and quickly draining the battery? Something besides app-oriented drains (like watching 6 hours of videos, turning the brightness up, etc.).
