First, I don't think anybody claimed that it will die. It's just not a great idea and other devices have been known to have such a problem.
As for mains, the Pocket Pro, as I understand it, only uses the USB port for power. There is no standard way to draw power in this manner other than to connect as a USB device and negotiate with the computer. If the software is broken, then this negotiation cannot take place and the device cannot charge. Furthermore, the device probably disassociates from the computer during the firmware update meaning it is no longer "on mains". Finally, it may be the case that charging/power management is entirely controlled via software. Thus, if the software breaks the device can no longer manage its power settings.
That being said, Hanlin has probably accounted for one or more of these scenarios. I know that the Sony PRS-505 (in addition to the power port) can trickle charge form USB without negotiation so at least one company has considered that emergency case. The Hanlin V3 (and possibly the V5) comes with a wall adapter (using the USB port) wherein the hardware engineers can play games with the USB port to allow charging even in the case of errors.
And all of the above to say that Hanlin, as an experienced company, is unlikely to have made the collection of errors required to "brick" your device. You are almost certainly okay no matter what you do.
