Fix PinePhone Pro when unable to boot due to drained battery

[fxc]

After charging the phone for several hours (~2-3h), I was able to boot the PPPro. However, the phone was still almost drained. I finished the initial setup and re-plugged the phone into my USB charger and finally my PPPro is charging as expected.


I was following the instructions but it still wasnt seeing any rockchip devices in lsusb, so what worked for me was TO ALSO REMOVE THE BATTERY, then press the reset button while connecting the cable.  Once rockchip reappeared , I then reattached the battery and released the reset button and continued charging

Removing the battery is actually part of the wiki instructions, would recommend to have an eye on the wiki whenever there is an issue, see https://wiki.pine64.org/wiki/PinePhone_P...structions.
