deagol · 04-24-2022, 08:53 AM

I checked my new KOA3 for deleted files I found this:

Code:

 -rwxr-xr-x     0     0 837831033  9-Apr-2022 20:21 update-XXXXXXXXXX-XXXXXXXX-XXXX-XXXX-XX

(I replaced the real numbers/letters with "X", to be sure to not share anything sensible.)

I renamed the file to update.bin and tried to check the content with kindletool but that's not working (de-obfuscating first changes the random garbage and the Bytes from Bundle but that's all):

Code:

kindletool convert -i update.bin 
Checking update package 'update.bin'.
Bundle         Unknown (0xD6421D4E [�BN])
Unknown update bundle version!
Error converting update package 'update.bin'.

The file seems to be just random garbage and the Kindle is also not accepting it as an update. Does someone have a pointer how to decode the file? Or is that just garbage?
