Do you know the part number of the daughterboard, or where I can buy a replacement?

Global Direct Parts seems to have OEM parts. Don't go with eBay and stuff. The ones I saw are cheap knockoffs that don't work right (even when they say OEM).

Do we need more adhesive or everything will stick back with heat?

I have replaced my battery. You most likely will need more adhesive. I just plan on using some double sided tape as the original glue was too tough in case I have to open it again. You can just buy a case for it after. It will keep everything nice and tight on there.

To replace the daugherboard, step #5 can largely be skipped - just remove the cable from the daugherboard and move on to step #6. This phone is a true PITA to take apart.
