Hi all, I hope you can help me with this one as I am out of ideas: iPhone 7 screen replaced. Back plate, home button and fron...

Hi Jason My first guess would also be to check the wifi:bluetooth antenna is plugged in well. The coaxial connectors can be very tricky and might seem 'clicked in' while they are not. They are also very dust sensitive so best clean them with some rubbing alcohol. Look at step 47 of the repair guide. The connection is on the bottom of the motherboard so it's easily overlooked that the antenna is dangling loose or not clicked in 100% iPhone 6s Plus Wi-Fi/Bluetooth Antenne austauschen

Hi, Could be you blew a speaker. Often devices like these are best not used for long at maximum volume. In the old days you could test speakers by using your device as a recorder (i.e. microphone) and see if the sound is detected. One simple experiment you can run is to plug your headphones into a microphone input, and speak into them. Fundamentally, both emitting sound and capturing sound is about dealing with vibrations in the air. The processes are opposite (one takes electrical signals as input, and outputs air vibrations, one takes vibrations in the air and transforms them into eletrical impulses). Otherwise you might try and check for debris or dirt that clogged everything up or a wire that is starting to become loose or gives distortion, thus giving a weaker signal. iPhone 4(s) often had the debris problem due to the mesh getting clogged up with dirt or sweat, especially after getting wet by rain and others. Good luck!

After hours and hours of trying, testing and comparing/eliminating I finally found it... Or so I hope. The device now boots nicely with everything working well. Only the proximity sensor seems a bit demanding before going dark but that might be a personal feeling as I am used to iphone 6 models going dark instantly perhaps :) My lucky stroke had some help: another iphone 7 that was badly damaged was brought in and did not need a quick repair so I could 'play' and compare. Solution: I taped over the back plate with some kaptan tape on the bottom where it's glued to the flexes, avoiding taping over the little hole in the plate but covering almost all of the glue residues. Also I straightened the camera flex. Everything now works great... Restarted multiple times. Seems like it was a bent flex or some false contact by means of the back plate. The other device I used for comparison & analysis also had a broken home button. Maybe this helped to better determine the cause... time will tell :)

Could be a problem with the IC chip (sometimes also referred to as the U2 chip) . You can probably use a charged battery but once it goes red/out it is toast, right?

Yep, it can be changed. Only the Touch ID function in the home button is linked to the motherboard. When changing the button you loose Touch ID but can still 'click'. Front camera flex is certainly repairable.

Om zeker te zijn dat je niet te maken hebt met een softwareprobleem zou ik toch eens proberen naar fabrieksinstellingen te gaan (na nemen van een reservekopie via itunes of de cloud).

Karsten Heeft het toestel ooit waterschade gehad? Ooit van die ventilatoren gebruikt die via de laadpoort hun stroom aftappen? De symptomen zijn vaak te linken aan hierbovenvermelde scenario's. Als je tot nu toe de laaddock niet hebt vervangen zou je geen contactproblemen mogen hebben. Je chassis kan echter gebogen zijn over de jaren heen en je nieuwe scherm is terug perfect qua pasvorm wat hier en daar wat trek- en duwkrachten kan geven maar niet een plots falen van de laadpoort en de andere erin verwerkte elementen. Misschien een kortsluiting gehad door geschonden of slechte kabel/laadblok? Of misschien heeft de accu hiervoor gezorgd? Hoe meer info, hoe beter! Laat maar komen!

Great manual. I was successful in this repair but bought a rear case with small parts. Safes up a lot of work and time :)
