So, i followed a tip, removed the battery, dried with a hairdryer, but the screen started to turn white, the camera was also white, I was making things worse. then I remembered another way to recover it. I dipped the phone in uncooked rice, so that moisture is absorbed, and after eight hours, the phone booted successfully and I'm installing it now gingerbread on it.
Here is a tip for someone to help if something like this happens. On contact with water, immediately remove the battery, dry the smartphone, deep it in uncooked rice and leave it for at least 24 hours to dry thoroughly and avoid damage. I left only for 8 hours because I had quite dried with a hairdryer, but this is a very risky technique as it can damage the display and other sensitive internal components.
