Screenshots:
—————————————


Important:
—————————————
• Use at your own risk!

• If you are new to jailbreak, turn off WiFi! (via Aeroplane/Airplane mode).
• Remove the update.bin.tmp.partial file (if it exists) from the Kindle root directory.
• Tested and works on these devices:
- Oasis 3: 5.16.2.1.1, 5.13.6, 5.17.1.0.3

• Warning! Block Device Logging does not work in PW1 and PW2. Avoid using this option or your system will brick.
- Reported in: #34, #56
If you experienced this problem, and you have soldering skills, then check this unbrick method.

Usage:
—————————————
Block OTA Updates:

Spoiler:

This button works similar as Rename button in renameotabin extension by @hius07

The following files will be renamed:
• /usr/bin/otaupd --> /usr/bin/otaupd~
• /usr/bin/otav3 --> /usr/bin/otav3~

As you might have noticed, the suffix ~ has been added to the binary files.

Warning!:
• UYK (Update Your Kindle) will stop working.
• You will not be able to update your Kindle via UYK.

Restore OTA Updates:

Spoiler:

The above changes will be revoked, UYK will operate again.

Block Device Logging:

Spoiler:

Warning!: One user bricked system in PW2 after selecting this option, it stays in boot logo and nothing happends. Avoid using this option, if you have very old device and firmware.

Amazon logs and sends to servers EVERYTHING you do on a Kindle, even every single tap and time in milliseconds precision.

When you select this button, backups will be created for the files below:
• /usr/sbin/syslog-ng --> /usr/sbin/syslog-ng~
• /usr/sbin/loginfo --> /usr/sbin/loginfo~
• /usr/sbin/tinyrot --> /usr/sbin/tinyrot~
• /usr/bin/showlog --> /usr/bin/showlog~

You can still find files with their original names, but they are empty because they are linked to /dev/null.

What are these files responsible for?:
• syslog-ng - syslog server and logging daemon
• loginfo - extracts specific information from syslog
• tinyrot - rotates log files to be fetched from remote servers
• showlog - specifies which log file to send

Warning!:
• Reading logs will not be possible anymore, the showlog -f command no longer works (it does not exist).
• Sometimes it is necessary to troubleshoot issues (manually or by entering in search bar ;dm command), especially after a Kindle Update.
• Log-dependent extensions, such as scripts displaying reading time will also stop working.

Thanks to @mergen3107 for the commands

Spoiler:

• /usr/bin/otaupd.bck --> /usr/bin/otaupd~
• /usr/bin/otav3.bck --> /usr/bin/otav3~
