Tes is a nerdy geek shop rat with a collection of precision pocket protectors. He tests his smoke detectors twice a year by licking the tops of their 9 volt batteries to see if his belly button will invert (to revert, just reverse polarity).
The steel blade tool is also great for removing the battery adhesive and back adhesive. Use like a dull chisel scraping up small chunks until done.
IFixit makes a tool about 5 inches long with a black plastic handle and a flat metal blade that is great for this. It’s a perfect prying tool. It’s about 4 inches of thicker plastic handle and 1 inch of steel blade. I would think if it was a sharp blade, it would be ideal for slicing through this type of adhesive. Like the dental floss idea also. Will try that on the next one.
Very excellent guide. Great pictures. Pictures must have been done in some sorta studio setting or edited for only what is needed for the illustration of every step. This was my first attempt at self repair on a cellphone, but I’m no slouch. I repair and refurbish all sorts of electromechanical devices and was once employed to do brain surgery on massive water cooled mainframe computers. Some of the same rules apply; have proven procedures, follow instructions, control your work space, and invest in the best tools. Since this was my first, I was not in a hurry. It took me all of 6 hours, but I was meticulous, repeated many steps to increase my confidence, and had all the time needed to do what I needed to do. Grateful for no longer being a slave to phone repair/insurance scams!! DIY forever!
