hi guys
i have done the followings several weeks ago, but for some reasons i could not post ot here:
i went to this thread and then this thread then i downloaded this file. after download the mentioned file i followed these steps:

Connect Kindle to PC with the USB cable.

1. Place the downloaded update_*.bin file in the topmost, visible level of USB storage (alongside of /documents).
2. Eject and/or Safely Remove (term depends on OS) the Kindle, USB storage.
3. Remove the USB cable.
4. Home -> Menu -> Settings -> Menu -> Update Your Kindle
5. Confirm
6. Wait

but in these steps:

1. Unarchive the release archive package.
2. Connect Kindle to PC with the USB cable.
3. Place the Update_jailbreak_hotfix_*_install.bin in the topmost, visible level of USB storage (alongside of /documents).
4. Eject and/or Safely Remove (term depends on OS) the Kindle, USB storage.
5. Remove the USB cable.
6. Home -> Menu -> Settings -> Menu -> Update Your Kindle
7. Confirm
8. Wait

my kindle said that this file is not valid (i am not sure what exactly the kindle said, i can test it again if necessary, because i have done these steps several weeks ago and for this reason i can not remember the exact phrases) and it could not install the update.
what is the problem?
