“extensions” must contain separate directories directly.

Maybe you can try first and see it for yourself?

So subfolder extentions shouldn't be there?I should,but newbie here to e-books and already jb took me many hours to find the correct files.I remember i had made an extra step that didnt know if it was needed (kual helper)So i am worried now if my jb will be lost.Btw thanks a lot for your help 😇

Do not put an extensions directory inside an already existing extensions directory.

As long as you do not do a firmware update followed by a reset you will not lose your jailbreak.

Thanks.To be honest idk how this extensions subfolder has been created there.So now to block OTA updates (so to just transfer files between PC) i put the extracted renameota.zip (3 subfolders) inside the main extensions folder.

The renameotabin.zip in post #25 has a top folder named renameotabin which contains 2 ordinary files and 1 subfolder named bin which contains 2 shell scripts.

Put the renameotabin folder and all its contents as is into the top level extensions folder on your G: drive.

Hello!

I have a Kindle Oasis 3 on FW 5.14.2, I just used KOReader's file explorer to check the /usr/bin directory and I do not see either otaupd or otav3 binaries.

Instead, I see a /usr/bin/checkUpdate.sh file. Reading the script, it seems to check for updates with Amazon, but I can't tell for sure.

Do you know if this OTA script is still expected to work for KOA3 on 5.14.2?

Thanks!

Edit: Never mind - I was wrong, doing an `ls /usr/bin` does show it in the terminal emulator, I guess KOReader's file explorer doesn't show binaries that it can't read

Reboots automatically, no need to kill the processes manually.

Does this work on a 5.13.7.1 Jailbroken KOA3?

Does anyone have secure information on this?

I have the same and it does work.

Just curious as it seems obvious to me but I can't find anything about it

Do we know where the kindles go for updates?

If we do we can add those to the network's DNS block lists or PiHole or the like to prevent OTA updates. Not that I'm saying that instead of this, more like having an extra layer of protection, like Birth Control + Condoms, it doesn't hurt to have more protection... I just don't understand why I can't find anything about it, even a "I tried this & it didn't work because Amazon uses multiple locations & if one is blocked it jumps to the next"
Thought this was the best place to ask, but if one doesn't exist I'll create a new Thread for it

Can't remember exactly, but this is what I used in past to generate the list of things to block on the Kindle itself.

# Block unwanted domains with the /etc/hosts file
echo ".d" | sqlite3 /opt/var/local/reg/ServerConfig.db \
    | awk -F, '/VALUES/ {gsub(/\047/,""); gsub(/\;\)/,""); print $3}' \
    | grep -o '.*\..*\..*' \
    | grep -Ev 'com.lab126|DOMAIN|WEBSITE|THUMB|openid.assoc_handle' \
    | sed 's/);//;
            s/^http:\/\///;
            s/^https:\/\///;
            s/\/.*//;s/:.*//;
            s/|/\n/g;
            /^\./d;
            /^\[/d;
            /^$/d' \
    | sort -u \
    | while read -r; do
         echo "Blocking host : $REPLY"
         grep -q "$REPLY" /etc/hosts || echo "127.0.0.1 $REPLY" >> /etc/hosts
     done

From an old backup, I think it's this one in particular to block updates, but it was a long time ago....

Thanks. Was it just one that needed to be blocked? & does anyone know if the reason 5.12+ sneaks updates is because they changed that?
