Hi everyone!
It's good to be back in a way. Even though I made an account only today, I used to read these forums a lot, when I had a Kindle Touch a few years ago. It still works like a charm with many hacks from this community. Thank you!
I now have a new Kindle Paperwhite 3 in the following configuration:
PW3 4GB WiFi-only (G090 G1)
Manufactured: August 2018
Firmware version it came with: 5.9.6.1
Special Offers: Yes
What I've done so far:
- After turning it on for the first time, I selected US English as language, cancelled connecting to WiFi and skipped the rest of the initial setup.
- Created the OTA update blocker directory "update.bin.tmp.partial".
- Connected to WiFi and registered with Amazon.
- Copied 2-3 sideloaded books on it and while it was still online, the Kindle managed to download all books from my Amazon account (around 25-30).
- WiFi has been off after that.
- (a few days later) Jumped with joy, when I saw that there is now a software jailbreak vector for my firmware version.

After reading the comments in the big jailbreak thread from the
comment where this was originally posted, the instructions here and in the
jailbreak Wiki, I'm aware of what to do in general, but I still have a few questions on how best to proceed in my case:
- Reading the comments that reported success, I noticed a pattern that they were all unregistered at the time of flashing the factory firmware (either as a consequence of resetting first or because they had never been registered in the first place). Should I unregister the Kindle before doing anything else (regardless of having to reset or not)?
- The instructions here say to avoid resetting a fresh, out-of-the-box Kindle and those in the wiki say to perform a factory reset (in Step 2). Taking into consideration, what I've done so far with it (and that there are books on it and the indexer would have populated its DB), does my Kindle still count as a fresh one or should I reset it first?
- Almost all success stories so far mention their devices were without Special Offers and mine has them. Could this play a negative role at some point? Should I remove them before trying anything?
To sum it up, I'm unclear whether, in my situation, I should:
- Unregister -> Reset -> Flash Factory Firmware -> ...
- Reset -> Flash Factory Firmware -> ...
- (jump straight to) Flash Factory Firmware -> ...
