I used 70 % isopropyl alcohol instead of 90 %, I don't think it was as effective as it should have been though.
I did step 7 before step 6 as I was afraid that it wasn't going to stick as intended. When doing step 7, but the back panel connector did disconnect from the back panel and not from the phone's inside.
