there are no screws underneath any stickers. you can remove the back plastic cover and access the motherboard by just removing the 6 screws. also, there are no ribbon cables attached to the back plastic cover. removing the cover can be tricky because it can first seem as though it is attached underneath by hidden screws. i repeat, there are only 6 screws in the back you need to remove to remove the back plastic cover that is underneath the back lid. this assumes you removed the back lid, then battery, then, sim card, then sdcard. the only thing in your way should be the 6 screws. i had to wedge the back plastic cover out with very tiny screwdriver. you can use a knife if you wanted. go along the edges and slowy poke the knife inbetween then lift and pry the cover out. it has notches on each corner (4 notches) and a few notches along the long side of the phone. (both sides).
