Yeah, that darn headphone jack gasket got me. I didn't notice it at all until it fell off the old assembly.
I concur with "jacobstevens". I just left well-enough alone. I made sure that the bracket was intact and that it remained so during the remainder of the procedure so it was ready to go when re-assembling. I also understand why this step exists... CYA!
Ensure you note the routing of the antenna cable. Reassembly will require that the antenna cable goes above the corner of the speaker enclosure.
Mr. Galan... Well done... the process for Battery Replacement of the iPhone 5c were straightforward and well documented. I was able to complete the replacement without issue. Much appreciated.
Wow, that was tough. Patience, patience, patience. Did not use the iOpener, just firm and consistent pulling with the phone on a flat surface. When the suction cup comes off... clean the display surface and go back at it. I did use the pointed end of a spudger inserted into the headphone jack to hold down the bottom case whilst I pulled on the suction cup. Once there was sufficient room (see next step) you can just get the spudger (flat end) to slide in slightly.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
