ZTE Blade A452 Display & Touch Replacement: Guide to Safely Work Around Non-Removable Battery

Hello. I have a problem with changing the display (and touch simultaneously) in the ZTE Blade A452.
The point is that this phone has a non-replaceable battery. And honestly I say that I do not know how to "take" for him. Normally, a man would take out the battery, take off the lid, unclip the ribbons, etc. But here I do not know how to "work around" the battery, and I do not want to do it blindly. I was able to remove the phone cover. I post a photo. Could someone advise me how to undress him? Is it too difficult? I've already mentioned the touch in Lumia 535 so I'm not someone who has two left hands .

And what is extraordinary here except that the battery glued to the body, you just need to peel it off

I do not know. I prefer to ask questions rather than trying to disassemble. Because, for example, I will unnecessarily break something and it will be bad: /.

What to unstick this battery. Separate the plate with a black sticker separately or is it better to remove the plate together with the battery?

Tinish the battery with the battery peel off, in such a situation you can gently help yourself IPA, so as not to bend the battery too much and do not tear on the chimney to not damage the battery.

That's how I thought I was peeling off the plate but IPA? I hear the first one, and google throws away some police organizations . Will you explain what it is?

isopropyl alcohol

Ok, does anyone else have any tips for what to watch out for?

If the battery does not want to leave, you can also heat it a little and pour a little of this alcohol then it will be easier to let go.

Hey, just a few days ago I broke my display (yes, the same model). For the first time I decided to name it myself, is there something I should know about it? Maybe some brief instruction / tip? I have never rummaged with the equipment itself, I would not want to destroy the phone completely.
Thanks in advance.
