its looking like we just had a bad batch of screens. derp. however we are still curious what the new sensor/chip off to the right of the new home button is. anyone have any ideas?

most likely you have a replacement screen that is missing the sleep/wake sensor. that’s why the old screen worked normally. it’s just to the left of the home button bracket if it’s there. compare the old screen to the new one and you should see the difference. or, the sensor on the new one is damaged. either way that is 1000% the problem. lots of cheap-o screens are missing the sensor.

we did finally receive several of these new (YF) versions of the home buttons. they do “work”, and give haptic feedback, but are very glitchy. Several times there have been random black screens that took several minutes to recover from, and at least one boot loop. The buttons also seem to get warm, and have sluggish performance at times, as if it has a delayed reaction. I cannot, in good faith, recommend using these current buttons unless they work out the bugs. If i have any say so in the matter, we will not be sending out any of these to end users.

is it possible the connectors on the screen arent fully seated? try to disconnect/reconnect screen connectors to make sure. many times they will look and feel connected but are slightly off. happens a lot in aftermarket mini 4 screens

now there’s this product. https://www.unionrepair.com/jc-universal-home-button-with-return-function-for-iphone-7-7plus-8-8plus.html seems to work. about to order a couple to try them out here

Posted this elsewhere but found this post afterwards: There are a couple ways to trick it if you’re using an aftermarket screen that does not have a sleep/wake sensor installed. First, update the pad to the newest OS since this work around goes away once you update or restore the device. We figured out some work-arounds a couple years back when we got a huge shipment of mini 4 screens that did not have sleep/wake sensors installed. You can use either of these two methods to achieve the same result. All you are doing is tricking the device into thinking the sleep/wake sensor is present long enough to get the “Lock/Unlock” switch to appear, which is not present until a smart case is detected. A.connect the original screen to it that has the sleep/wake sensor attached. Turn the device on. Using a smart case (or a magnet in just the right spot), get the device to sleep/wake when closing/opening the device. You will hear a “click” as the screen goes black. In settings, go to Display & brightness and turn off...

i just had this same issue while trying to repair a 6s. i get the same error message "software for this iphone not currently available". Have the latest version of iTunes, and the latest version of 3U, which basically tells me it can't detect the device type, and doesn't know which version of iOS goes with the device. The device itself has a black screen even when powered on, and shows no other signs of issues other than a standard cracked screen. It has never been repaired or opened before today. Any suggestions? Just to clarify, this is NOT a computer or iTunes problem, as we repair hundreds of iPhones and iPads at this repair center every day, so all of our machines are up to date with the latest software and running correctly. Connecting this device to any other machine in the building yields the same result. Obviously to me, there's something going on with the device and it can't be recognized properly.

it all depends on whether or not the restore works or not. If it can't be restored via iTunes or 3u, then most likely it has logic board level problems. At that point unless he's offering it to you at a very cheap price it would not be worth it. As the user above mentioned, we need more info to give you proper advice.
