completed battery replacement, touch screen & home button don't work
I completed the battery replacement per the guide, including plugging the little internal cables back in which was rather finicky. I have not yet snapped the case back together, since opening it was such a pain, but I tried powering up the phone. Results:
- Power-up button doesn't seem to do anything by itself, even after holding it in for a while
- Connecting power bank to lightning port lights up phone, shows monochrome apple logo, that goes out and comes back on about 5 times before booting phone. Phone eventually turns on and says battery is charged to 100%. This battery was purchased new from ifixit about a year ago and i haven't really recharged it, so I doubt it is actually at 100%.
- Phone eventually comes up enough to request unlock code (it's not my phone and I don't know the code, but the owner is around and can enter it if necessary). However, entering digits on the screen seems to have no response at all (buttons temporarily lighting or whatever) so it seems like the touch screen isn't working. The home key similarly also does nothing.
- I tried unplugging and reseating the home key button, no change. Doing that with the touch screen button will require re-disassembly of the phone (the 4 different tiny screws holding the cable shield on) so I haven't tried that yet, but can do so if necessary.
I'm not an Apple user so don't really know how an SE (or other iPhone) is supposed to react on powerup, so maybe some of this is normal.
I still have the power bank connected to the lightning port but the leds on the power bank were off,. indicating no current being transferred. Turning it on by pressing the button lit the screen again. The screen times out (goes dark) after a while, and pressing the power button on top of the phone does turn it back on.
Does this sound like an error reconnecting the internal cables? The display itself seems to show stuff properly so that reconnection worked.
All suggestions appreciated--thanks.
