What's the method for performing the update WITHOUT using an SD card (which is obviously needed in this case)?

No link.

As suggested by rprosperi it is possible to update the ROM via usb. You will need the HP 50g, 49g+ and 48gII PC Connectivity Kit & HP USB Drivers. In the hp4950v215/ hp50g ROM Upgrade.pdf it is explained how to do it and all the bugs fixed are listed.
