Dropped my iphone in water need

So I recently went to the beach long story short my iPhone was swing for about 30-40 seconds and I quickly dried it off and stuck it in a bag with my clothes. Then on the way home I tried plugging it in but got no response but there was water on the charger after taking it out so I didn't try charging it again. After getting home I put it in rice. Few hours later I took it out and opened the phone and dried some of the water inside. I then took out the battery and other components then reassembled because I didn't feel comfortable dunking it in alcohol and I didn't have and other tool like the ultra thingy. Then I had it in rice for a about 2 days now and take it out to plug it back in. At first there was nothing until the red battery showed up then went away a couple of times then the apple logo started to show up for about 3-8 seconds and disappeared. I don't know if its the battery after taking it out that s not turning on the phone and now I just need a new battery or is it something else(ps. This is all happening rn)

Can you still see blocked messages on an iPhone x?

I blocked someone and I see that on my voicemail list and call lists, there seems to be an option if you can see the blocked messages but I did not click on it. And this device is still new to me. So for those who have an iPhone X, can you see blocked text messages? The whole point of blocking is so you can't receive or view them and to not receive it in the 1st place, it seems like you can still receive voice messages from a person who you blocked. How do you not receive voice messages or anything at all if you block someone?

Added (1). I hesitated, but clicked on it and saw it was a voice mail but no text message.

How to factory reset my iPhone 6 plus without itunes?

So my friend gave me an old phone of hers to use while mine is being fixed. It was dead when she gave it to me, so when I went home to charge it, it said "iphone disabled, connect to itunes." I asked her for the itunes information so i could factory reset the phone; however, she told me that she did not know it. Is there any way that I can reset this phone without the itunes information?
