My iPhone did an update tonight at midnight (at least I think). Since then it has not been possible to start. I was on my cell phone at 00:02 am when it suddenly turned off. If it tries to start now, it only shows the Apple symbol and stays that way. Until I can suddenly press the home button again, which shouldn't happen until it has finally started up. Well, after a while it goes off (probably due to a lack of battery) and either shows the battery and the Apple logo again. However, it can't be the battery, as it is permanently attached to the cable.
I've also tried to do it in Recovery Mode, but it isn't recognized on iTunes. But it can't be the cable because it also charges on the laptop. I have already looked in Device Manager, but it is not recognized.
Now my question is: what else could I do?
(iPhone 7, iOS 13)
As already mentioned, I have already done this.
However, it is still not recognized, but, as already mentioned, this can't be due to the cable as it can charge normally on the laptop or on the socket. (It's an original)
Then it will be broken. Get it fixed.
