I have a used Kindle Paperwhite PW3 with firmware 5.12.4 for which I would like to block firmware updates while using wifi and amazon registration of the device. A
jailbreak procedure on this forum matches this device and firmware version, and that one I believe I could follow and use.
But the subsequent procedure I found for actually blocking the firmware updates is beyond my understanding as I'm lost just with what 'ssh' means. Is there a procedure that a novice could follow? Thanks.
