Speaking as a recidivist n00b. This would be useful. It would save me some time. It's been a while since I have.

Maybe bringing it all together in a wiki crib sheet linked to a 'spare and repair' wanted/donor list.

First linking to the archive of the images and flasher, so not inadvertently clicking on the malware infected installer.

The option of flashing from linux instead of win 64bit. Cold flashing a corrupted boot, and flashing from the SD card if you can install a bootloader, but lack a usb port.

(A bespoke live linux boot image to a flasher would be nice. Something like http://build.porteus.org/ maybe, being designed for USB use. I like how you set the config before you build the image.)
