Jeff - I don’t know about kolorec, but I did read thoroughly, and stayed well away from the volume controls during the long and worrying battery extraction. However, I managed to damage the cable at the other side - where it comes up to plug into the logic board, near the display (etc) sockets. I suspect the dental floss was the culprit, but it might have been the chisel (joke!). So I have a working phone but have to adjust volume and power off in software.
I would echo most of these comments. I tried to be very careful, but still managed to pop up the display (it was very tight indeed), severing not only the home button but, as I later discovered, a cable at the other end of the phone.
Really, get the proper tool.
