Well, clean it one more time with some IPA... if that doesn't work, you can print your own boards, but it requires a lot of different, hard to get materials and only some household printers would be able to do this. If the IPA doesn't work, try some WD40 and leave it to dry. If even that doesn't work, go to ebay and find a mother board for your phone, or a broken phone like yours to take the MB out.
If you won't find anything on the net to buy, you can always look up some tutorials on YouTube

.
I already done all that cleaning.
Have i understand this right, can i make new board? It sound really hard. Let say you print your own board, but then u need to put all the electronics on it?, like ic and stuff?... If its like that its crazy. I don't even think someone will do that.
However i would like to learn about pcb work. Do you have some good reading/movie?
I thought i could make new tracks on board with a Conductive Silver Pen, will it work?
