I replaced my first iPhone 7 screen and although it tested OK straight from the box when I came to the full install it was very slow to boot and then went into boot loop. The Apple symbol showed for about 10secs and then seemed to die but came on again repeatedly. I disassembled, including disconnecting the Home button, reconnected the digit and LCD flexes and again it tested fine. Reassembled everything but this time I more carefully reseated the Home button and this time all worked 100%.
Thanks SectorGaming. ...makes sense and I think the micro soldering will be beyond my repair skills. I will send the board back to China where there are specialists for motherboard repairs. Thank you for taking the time out with your advice.
You can substitute the home button (on the short flex) with an after market one (they are very cheap about 5$) but this will not revive your Touch ID facility as you will know the originals are manufactured to uniquely pair with each motherboard. Everything else should work on the new button.
Hi Grace...we need some more information....when you plug in your charger, do you get any symbol come up on the screen with a battery symbol ? If not you could try a different charger and cable, if you can borrow one perhaps. If this doesn’t jump start it, you may have a problem with the battery (they do have a limited life span). Good news is that they are cheap and easy to replace (see the iFixit guide on this replacement.) Lastly you may have a charging port where you plug in, blocked with minor debris (the main culprits are pocket fluff, hairs, wood dust etc. )....all of these can be carefully eased out with a needle or long pin. You may then find your charger will bring up the charging icon and your phone should then fully charge in about 2 to 3 hours.
You need to peel off the fabric tape from the complete width of the old screen and apply it to the new one, covering any exposed metal surfaces. Stops any jittery instability...worked for me !
Try lifting the motherboard from the battery contacts for a few moments and then reseat it again ....sometimes I think this discharges static or just makes a better contact. Make sure power is off and to be safe disconnect the cable from the daughterbd ( comes across between the battery segments). This has worked for me on several repairs.

Found this by trial and error with iPad 2 backlight not working.....I have often had a very faint image on the LCD screen after switching motherboards. EUREKA moment !! Take the board off the battery contacts momentarily and usually the screen lights up in wonderful technicolor on the new contact. It's only my humble guess but maybe it discharges some static or makes a better contact second time around but it sure beats having to repair the board.
I have been replacing screens on iPad 2s and have come across 2 iPads with rear cameras not working. In each unit the camera app brought the"iris" image on the screen. In one, the iris briefly opens but doesn't show a view and then closes again quickly. In both iPads I have replaced the rear cameras but nothing has changed. I tried reseating the cameras several times, with and without screwing down the covers. I have tried software upgrades and complete resets. Can anyone suggest what this means.....logic board replacement or just put up with not having the rear camera. After all, the front cameras still work for FaceTime at least.
