    Step-by-step guide for any Lenovo P8 (no matter of OS, because this is a clean flash). 1.1. For stock Android 6.0 devices, you should take into account that LTE does not work in Europe. If, somehow, LTE works, then go to 1.2. Else, you need to flash 8703N via QFIL (chinese firmware) which has...

    The problem with offline charging is not a custom ROM related, but Android Pie. A reboot (or a cycle On-Off) is enough to solve the problem.
