Thank you for contacting us.
We would like to recommend Fixppo to you.
The standard mode can fix various iOS problems like device stuck at Apple logo, black/white screen, recovery mode etc without data lose.
The Advanced Mode can help you to solve the problem of screen lock, but one should note that all the data on you device will be erased.
However, we can not guarantee that it can be 100% fixed. Our program can fix the iOS issues, but if there is something wrong with the hardware, we afraid we can not help that.

Have a nice day!
Sincerely,
