I use 99% isopropanol to dissolve the solvent, works just fine, not quite as angry of a chemical... I did not need to take anything out other than a couple screws around the battery itself.

It was a surprise to me that the P6a screen part did not come with replacement adhesive. I didn't discover this until I had my phone apart and went to open the package the screen came in... so, learn from my mistake!

IMPORTANT NOTE - if you buy the screen "part only" it does not come with adhesive!

If you already have the tools (and I have all the iFixIt stuff), ordering the "part only" means you'll have to get the adhesive separately, with another postage charge. Quite frustrating! Yes I suppose it's written down somewhere...
