Opening your phone will compromise its waterproof seals. Have replacement adhesive ready before you proceed, or take care to avoid liquid exposure if you reassemble your phone without replacing the adhesive.

If your glass is shattered, put packing tape over the entire panel to hold it together during the removal process.

Lay the heated iOpener over the rear panel for about two minutes to loosen the adhesive around the edge of the glass.

You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

Shift the iOpener to heat the remaining section of the panel for another two minutes.

A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.
