Short answer: Yes, if 'update kindle' button is not grayed out

Longer answer:
This update_*_.bin file is "Model Locked" it will not install on a model that it is not intended to install on.

Post the first four characters of your device's serial number and the author of this package can tell you if it is included.

The 5.3.5 firmware is from Amazon.
Unless they screwed up, the answer is: yes.

The messages of the jailbreak (written here) are probably English only.
But if the conditions of the above answer are met, the answer is: yes.

Thanks.
That would be up to the author.

But continue even if you don't have the checksum to compare with that of the downloaded file.
These update_*_.bin files are internally checksummed and cryptographically signed.

The cryptographic signature on the package will fail if a single bit is disturbed in the download process and the installer will exit with an error message immediately.

Support for the above is the reason why you have to do the device jailbreak first before using any of our packages, that installs our certificate into the pool along with the existing Amazon certificates.
