removing the display from the gold iphone NUMBER_TOKEN pro it's now time to get out the logic board this can be done by removing the sim tray and the NUMBER_TOKEN cables connecting to the board in removing just the display and now the logic board we've used four different types of screws two of which are security screws after the cables and two standoff screws have been removed the sim eject pin needs to be moved out of the way now the board is free carefully maneuvering it out of the phone we can get a look at it in a similar design to previous iphone models this iphone board has once again returned to having a soldered in sim reader in the iphone NUMBER_TOKEN the reader was modular i was able to upgrade a single sim iphone NUMBER_TOKEN to support two sim cards but that won't be possible with this model now that we have one logic brought out i'll need to retrieve the other one before we can swap them across i want to make sure that the symptoms if any are the same across the two devices as i'm working i'm keeping track of all of these parts and components on several magnetic mats laying everything out helps me keep track of where things go when it's time to reassemble it's now time to swap the two boards this process doesn't sound like it would do anything after all they're the same model of phone and everything inside looks the same while the hardware of the phone is identical the software of most components from the cameras to the vibration motor have their own serial number if the software were designed in such a way that if those components serial numbers changed it could break or limit functions of the device this is what happened with the iphone NUMBER_TOKEN. now that the board is installed everything else inside the phone is from the other device let's see how it reacts after powering on there are several messages from the settings app unlocking the phone displays an important camera and display message forced to tap learn more it says these parts are unable to be verified as genuine apple components we also see an unable to activate face id message tapping learn more on any of these messages will take you to apple's website where it recommends you to service your phone at apple this is what we saw with the iphone NUMBER_TOKEN however the NUMBER_TOKEN takes it a step further with even more issues arising which we'll get into for those unaware the battery health has been purposely disabled along with face id and true tone digging a little deeper i tested a variety of functions on the phone including the cameras i found that portrait mode and the new cinematic mode don't function correctly when using the selfie camera cinematic mode allows you to press record but the time never increases and no video is saved in portrait mode the background does not blur but you can see it detects my face but refuses to take an image saying to move further away no matter how far i move it doesn't work this also tends to lock up the camera app in the process before jump into conclusions i'll try to replicate these issues on the other iphone NUMBER_TOKEN. it will have the same setup as the other phone all genuine new apple parts just from a different phone
