Ringer and volume controls didn't work.
The disassembly went smooth with your step-by-step guide. A little problem came up with the removal of the silence switch. A small piece of metal came off of the back of the switch and I had some difficulty figuring out how to reassemble the switch and there were no pictures of the switch. Finally figured it our through trial and error. Thought we had to replace the phone until locating the fix on Google search to your site. A little difficult but very fruitful. Thanks.
A few pictures of the switch and a warning that the small metal plate might detach would have been helpful.
