tldr: patience is key. learn from experience. don’t cheap out.
So I bought one of these B7000-looking glue called Tree Frog Cobbler Glue from a local online platform. I liked tree frog’s CA glue ’ cause it doesn’t dry up so easily and the hold is strong.
I initially liked this one for phone repairs since it actually holds up unlike my experience with B7000s before. I had successfully repaired numerous phones until I had to repair my iPhone 11 I got from my brother and was annoyed that one corner of the screen wouldn’t sit flush with the housing.
The phone already had a replaced battery and screen (an LCD one). Battery was already buggy (charges to 97% in 30 minutes wont reach 100%, gets down to 3% quickly and would stay there for hours so you wouldn’t know how long the actual battery would last). Otherwise everything was fine.
But to fix it cheap I wanted to repair it myself, just cause someone my friend knew quoted a price thrice the price of a decent battery. So I got into it, replaced the battery successfully, but broke the earpiece flex. What an expensive mistake! Since retaining FaceID and true tone required paired parts with serial number. To cheap out again I decided just to replace the earpiece assembly myself at the cost of FaceID and true tone. It WAS finally done until I put the too much of the cobbler glue due to my slight annoyance of the corner that wouldn’t sit flush and it f***ing fried the LCD screen! I thought this type of glue was not conductive. Now my total cost was even more than the initial quotation for battery replacement. And lost FaceID. Goodness gracious.
The glue also burns out plastic (see the taptic engine on the left and the speaker on the right). I actually experienced it before trying to fix a mouse whose skates won’t stay straight. Maybe I should be content with how things are. Or maybe I should hyperfixate and break things even more!
I don’t know if B7000 does that also.
