Thanks to Thomas, I did the turning on to know if it vibrated or not trick, and in my case, it did not. I had to plug out the battery connection and plug it in again with a finger and it was then when I heard a little “click” sound, and then the phone vibrated. You have to ensure that the battery side connector, sits right over the battery connection, before pressing it firmly.

Leaving one pick inserted at each corner will help prevent it from sticking back.

Use isopropyl alcohol with a syringe at the top and bottom speaker to weaken the adhesive, gently pull apart (about 2mm) and use a finer piece of plastic (like a milky file plastic sheet) to cut through the adhesive at the speakers, but still do not take the screen off completely yet! After extensively reading about failed attempts to get the screen off (instances where people damaged the OLED underneath) one thing is in common: few devices have little adhesive underneath the ribbon cable as well, which people failed to notice and while separating the screen and in turn, damaged the OLED because of the pull from the ribbon cable. Thanks to having this information beforehand I found the same issue in my phone after I separated the screen (not completely) from the frame, I used a piece of finer sheet of plastic to cut the adhesive holding the ribbon cable. You will have to be extremely patient and take your time.

The first pry to get the pick inside the edge of the screen needs A LOT OF HEAT and a very firm pull, and just as someone else mentioned, the iOpener did not work well, instead, a regular hair dryer proved more beneficial in applying a controlled amount of heat until its almost too hot to touch. Then, once the pick is inside 99% isopropyl alcohol worked wonders, use a syringe or dropper to apple some at the edge, wait for about 15 seconds and move the pick centimetre by centimetre. Make sure to not insert it more than 2mm at the sides. I took more than an hour just to get the screen off.
