Hi Vince, unfortunately my phone did boot up, I felt the vibration and it rang when receiving incoming calls…After comparing it with the new replacement I think it was the display cable connector pins that I accidentally broke while plugging the cable. See https://imgur.com/a/SuItoIN and the two panels side by side: https://imgur.com/a/mL6UjGh . If you can see it clearly it might well be the top-right part of the pins that’ve gone missing…It’s really disaster…I’m just over-confident with myself :D Hope this post will help whoever doing this in the future and be reminded that anything can be broken.
I’m screwed. Screen doesn’t work after replacing the battery. No sure what went wrong…placing order for a replacement screen now :(
Took me another ~30 mins to remove the midframe…AFAIC this part is more tricky then removing the screen…just remember to follow the instructions - i.e. apply inward pressure.
Just in the process of replacing battery…The prying part wasn’t so hard as I’ve imagined…took ~15 mins, and here is a photo of the back of the screen. https://i.imgur.com/W0C2JHl.jpg .See the red rectangle? I might have ‘damaged’ something so be really careful dealing with the lower half of the frame. I’ve re-powered on and display & touch are both good.
