Very Happy to report another 2 Jailbreak successes...
2 Paperwhite 3's G090 G105 English language (for the records)
I used the easier instructions from this post:

I checked the Kindle root directories after the procedures were finished via my Win 7 laptop, and both PW3's now have a "jb" file and 2 new folders?? "mkk" and "rp"
Both are still on 5.6.5 and are back protectively in airplane mode
Awaiting any news on being able to survive OTA updates from Amazon, since from what I have seen so far, I am not interested in the "improvements" by going to 5.7.2 (especially reports of the Helvetica font becoming THINNER on PW3's)
Now I am off to explore all the other goodies/options that are possible with the JB having been accomplished....
Thanks so much to everyone involved in making this happen
