New out of box phone, vibrates and solid red light on charging

[fxc]

Just got new in box Pine Phone Pro, i pulled tape off battery.  reinserted, used usbC cable supplied and different chargers.

However, no matter what I try, the phone just vibrates endlessly and has a solid red light when connecting cable.

The battery probably discharged too much, so it can't continue to boot in that state. I would suggest to remove the cable and to power the device off, then hold the "volume up" button and reinsert the cable to make it boot into Tow-Boot's USB Mass Storage mode. The LED should turn blue while doing so. Let it charge there for multiple hours. If that didn't fix it you can also overwrite the eMMC from there.
