PW3 Lost OTA binaries

[a1732613278]

Recently I've tried disabling ota updates.
The whole process was successful through renaming ota binary files
https://www.mobileread.com/forums/sh...d.php?t=327879 *this method
However,I've clicked rename button twice by mistake,the script ran again and replaced my original backup files.
Unfortunately, I have no other access to these two essential files that I have only one kindle.
Can somebody send me the original ota binaries?I would appreciate it very much if you can help me.

OTA files:
otav3 at /usr/bin/otav3
otaupd at /usr/bin/otaupd

KPW3 FW 5.14.3.2
thanks!!!

You can use KindleTool and extract it yourself from the update file.

First, download the update file for your device here.

Second, go here and download KindleTool for your operating system and unzip it.

Third, open the extracted directory in the terminal and run

./kindletool convert ~/Downloads/update_kindle_all_new_paperwhite_5.14.3.2.bin

Then you will need to extract the converted .tar.gz.

If you open up the extracted directory you should find a rootfs.img.gz file. Extract that.
You should now have a rootfs.img file.

If you mount that using somthing like

mkdir /kindleUpdate
mount -t ext3 ./rootfs.img /kindleUpdate

you should find the two ota* files in /kindleUpdate/usr/bin/.

P.S. this probably only works on Linux and maybe OSX.

Here you go. I just did it myself real quick.

Thanks a lot. I haven't used kindle tool before. It's really a nice stuff.
And I'm not going to modify any system files anymore.

Pressing the Rename button for the second time cannot kill the backups.
