Hello, if the flex cable of home button is missing(I’m waiting the missing part) the screen could run without it ????? Because my phone screen doesn’t work at all . Thank you.
A broken Home button flex should not stop the phone from functioning properly, home button functionality notwithstanding. If your screen assembly is not working, you either have a defective screen or you damaged something else while doing your own repair. Go back through this guide and double check all the steps. Also be careful to always disconnect the battery before disconnecting the screen otherwise you may damage the backlight circuit. So I would try these steps: Double check that the flex connectors are properly seatedVisually inspect, preferably with magnification, the condition of the connectors on both the flex cables and the logic boardAlso look to see if any components appear missing or damagedShine a flashlight on the screen to see if you have a very dim image. This would be indicative of a blown backlight circuit. Hopefully your problem is modular in nature otherwise it may require a micro-soldering repair.
