And if your computer is running Windows10...what then?
While following steps 4-5:

Connect the phone to an USB port of a computer, while still holding the button for some time
...Windows10 did make the same sound it always makes, when a USB device is newly connected. Though, as expected, nothing shows up in File Management. Is that sound-byte any indication that power is now being transferred to the battery? The LED on the front of the phone did not come on. Nor does the phone offer any indication that the battery is charging.
Though, while the battery is sitting at just above room temperature, the phone's Quectel EG25-G unit is generating mild heat.
For reference: Desk: 25.8C, PPP Battery: 28.4C, Quectel EG25-G unit: 30.2C.
That seems...promising(?).
I do have the keyboard addon. Is there any way to insert the phone's battery in that unit, and charge it that way? Or can I simply charge the keyboard unit separately, and then utilize that as a power-supply?
The sounds are a good sign but a better one would be to check the device manager for an unknown device, which should have the VID 2207 and the PID 330C in the device properties, I think. Please do the charging without the keyboard being attached, as using the USB-C port of the phone while having the keyboard attached is not recommended and probably doesn't work properly.
Charging the keyboard separately won't help with the drained phone battery as U-Boot is bootlooping due to a bug with a drained phone battery and it won't charge properly in that state either, until Maskrom mode is used.
