this will disable the hall effect sensor / magnetic sleep cover of your kindle.
my kindle keeps on waking up from the magnets of devices around it so i came up with this.
Tested on KT4 PW4 PW3.
Should work on KOA KV KT3 KT2 PW2.
If you have a KOA2 KOA3 PW KT: I should be a be able to extend this to those platforms with some info from you.
