Edit: About downgrading, I'm not sure. I've never had to downgrade before.

The OTA blocking method over at that thread works fine on my KT4 @ 5.12.4. And given the rationale behind it, I can't see why it wouldn't work on later firmware versions, barring some internal consistency check made by the FW to restore OTA daemons tô working order, or additional binaries / daemons added for OTA on later versions.

I also have the OTA daemons renamed but I'm still hesitant on turning off airplane mode. Until it's more widely tested I don't want to recommend it to anybody personally. After a month of work to jailbreak my KOA3, I don't think I could handle if it all just went away for not being careful.

It may not sound like it on that other thread, but I did some extensive(ish) tests. I've been leaving the wi-fi on my kindle on all the time ever since. From time to time I pull up an ssh session and check out /mnt/us, and no update file ever showed up. Looks pretty solid to me.

Tomorrow I'll look into the binaries and check for code that download from amazon's servers. Maybe I can convince myself with that, if not then it'll just end up being some extra research for the OTA blocking thread.

Do someone know if when Koreader is running, if I turn on the wifi on koreader, the OTA upgrade might happen? I love the calibre connection in Koreader....

Which firmware are you on? If you are on a version that the KUAL helper extension can block, this is safe. If you are on newer firmware then only airplane mode or removing/renaming the OTA update routines can make this safe.

Keep in mind the kindle firmware sits on a linux foundation, which is inherently multitasking. Unless it is prevented from doing so that OTA routine will do what it was designed to do.

Don't forget Hius's blocker, that works on firmwares > 5.11

@bnpssilva: It's technically likely, as the OTA daemons aren't frozen.

I'm still running FW 5.9.x, so what I *can* say is that everything's peachy with a sane OTA block, though.

Since there are so many people reporting that this works, I added this post/thread to the OP with a warning. Hopefully we can get some more tests from other brave users.

I think this blog / channel is the reason why I bought an Oasis 3 instead of a Forma, so they are the reason why the jailbreak exists now.

(I'm sure somebody else would have made it if I didn't though.)

Well, I tried my luck with my KT4. Created the folder update.bin.tmp.partial, installed the rescue packs, turned on the kual OTA blocker; Then turned on the wifi. Unfortunately it was upgraded to 5.13.4, destroying the jailbreak. Is there still salvation ? I tried the emergency-bridge-recovery.zip, but I think it didn't work...

Which blocker? Rename OTA binaries or PREVENT OTA Updates from KUAL Helper?

How did the upgrading process start? Just by itself or asking to reboot?

I used PREVENT OTA Updates from Kual Helper. And it was KT3, not KT4, sorry.

What was the firmware version before the update?
