There was no problem I just thought that the transparent back mod was cool.
It was quite easy... Take out the screws... push a bit... replace part.
I decided to use the regular screws rather than the philips ones so I now have a backup.
I did not read all the description of the product and had to order the "liberation kit" after I got the replacement back in the mail. For some reason I thought that the back came with the needed tools.
