I tried downloading 3 different sets of icons from that site, using the instructions they provided. Didn't work.
For those that have the barcode I scanned it, saved it to my phone but when I tried to unzip it my phone said it was unable to do that. Same thing happened when I saved the file to my computer then emailed it to myself.
I msgd a couple of ppl for help on their forum but only one answered back and basically told me I was too dumb to own an Android phone
