[coplate]

Here is a version of usbnet installer that should work on any touch screen kindles up to 2017-08-07. I have left this in the form where it can be applied to any software version. "scratch" will be my shorthand for these packages where there is no 'target OTA', which should let it install on any newer version of the OS as well.

It is still model locked to all of the hardware I know about right now, but this includes all known oasis models and all know paperwhite models ( including manga version )

Spoiler:

Made with this command
