I dont like using super glue. I know it’s mostly not popular at all to use, but if you get a gorilla glue micro pen or some type of super glue with a controlled flow use just a tiny dot in the corners and one half way between each corner. The iWatch screen is very light, so a little bit will hold it. I’m not sure why, but I have the same issue you are having about every 10th iWatch I fix.
Liquid damage is really tricky. There are no two like scenarios. First of all, I would not use the iPod anymore until the board is properly cleaned with either an ultrasonic cleaner or some high percentage alcohol. Second, youll need to replace the screen. It sounds like the backlight and possibly the lcd itself is dead due to the liquid damage.
Not usually. As long as the adhesive is under the battery and not bunched up, youll be fine. The only adverse effect I can think of is if the adhesive is bunched up your battery may press against the mid plate on the screen causing LCD bruising that occurs when pressed in that area.
So you have the “press home button” message and you cant do so because the button is broken? If this is the case, youre in luck. There may be other ways around it, but the iPhone 6 home button is easily replaced. They are also cheap and can be had for less than 5 dollars.
Did you make sure it was clicking before the laying the screen back down? The black bracket has to align almost perfectly so that the raised dots on the bracket and home button touch. That’s what gives give the click. If they are misaligned then it’ll either be jammed feeling or mushy.
In my experience the only way to get it straight (depending on severity of the bend) is to buy a new back housing and transferring the guts of the bent iPhone into the new housing. I’ve done this before with good results. Many times when you try to bend back the housing you can cause damage and in the case of the iPhone 8 you have to worry about the glass back breaking as well.
