Tools BinaryRenamer - Block OTA Updates & Device Logging

[Daviteusz]

BinaryRenamer
Block OTA Updates and Device Logging

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.
• If you use renameotabin, you must disable WiFi and Restore OTA Binaries before using BinaryRenamer.

• Tested and works on these devices:
- Oasis 3: 5.16.2.1.1

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
• Source: 4PDA.to

Restore Device Logging:

Spoiler:

The above changes will be revoked, Device logging will operate again

1. Copy the BinaryRenamer folder:
• Via USB: to /extensions folder

2. Run KUAL
3. Open BinaryRenamer
4. Block or restore what you like!

Cool! Thanks for making this and testing it.

For your todo #1, have a look at NiLuJe’s fbink.
On JB device, you should already have it. fbink is really easy to use, just type fbink in the ssh to see all options.

BatteryStatus is a great example of fbink printing.

Thanks! Looks promising:

I would also strongly suggesting double-checking whether this doesn't cause random stuff to busy retry-loop like crazy (... which is going to be harder to double-check without logs ;D).

I did multiple tests with different conditions and on two different devices and on my Kindle.

Although there is always the possibility that I may have missed something.

But...
I tested via sh -x and it works fine and only on the specified files as long as the conditions match. If the conditions are not match, the script does nothing

Version 1.0 released!

- Completed all TODO objectives

If you would like to motivate me to keep working or would like to buy me a coffee, you can do so here:

I can confirm that this blocking still works.
I disabled them on 12/03/23, exactly a week ago.
Today, after multiple restarts and stuff, I can see that there are only these files:

There is no messages file (the one that would be shown by showlog -f), and all archives are no newer than 12/03/23.

[weirdGiraffe]

Sorry if this is a stupid question, but what's the benefit of disabling logging?

[mergen3107]

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

This script prevents all of that.

You can request your data from Amazon, you will get surprised.

I forgot to add info about this, thanks.

[arooni]

Is this the consensus best way to keep my kindle jailbroken? Want to keep koreader on my scribe.

[mergen3107]

Yes. Please do not cross post.

[mergen3107]

FWIW, my less than a month experience is still good: https://www.mobileread.com/forums/sh...&postcount=580

[arooni]

If I've already run renameota is that enough or do I need this too? Should I uninstall that first prior to running this ?

[mergen3107]

They do the same thing as far as OTA is concerned.
