You are right - 8 characters fionaXXX password from webpage works.

Did you use the update file posted by Amazon?
If so we can look in it to see if it patches /etc/shadow.
I used the 4.1.0 update file posted by Amazon.

Thanks.
No changes noticed, but then you found that out yourself from the web-page.

If you look at the shadow file at the link you posted, you can see that the framework password is an MD5 has because it starts with |$1$|, but the root password is a DES hash because it does not start with "$". DES only uses the first 8 characters of your password.

You can edit those shadow files, and replace the hash strings from another shadow file. That is how I changed the standard (serial-number depended) fionaXXX password in diags_ssh (by copying it from a K4 "mario" shadow file into the K5 diags shadow file. I thought it important that diags_ssh not use somebody ELSES fionaXXX password, and "mario" was a good choice. Using the passwd command to change it would have changed it to an MD5 hash, and I wanted to keep the original DES hash, so I just copied the hash instead.

Are there any method using copy-paste scripts to Kindle (Like one for 4.0.1 firmware), not connect to Linux console?

You can mount and modify a firmware image file before flashing it. In Windows, I use ImDisk: http://www.ltr-data.se/opencode.html/

Did they work after you restored mmcblk0p1.img but before you did the update?

Didn't try this. Is there any way to rstore it again? I can't access through ssh to command prompt, but what if flash diags (mmcblk0p2.img using fastboot mode)?

Hmm...
So we do not know which change made the difference, the image you loaded or the update.
Either one might have caused this problem.

Will leave this thread for someone who knows the K4 better.

I restored Kindle flashing 4.0.1 images and before the update to 4.1.0 mario password worked fine. But after update mario and fionaXXX doesn't work. Maybe it happend after I flashed mmcblk0p1 and mmcblk0p2 from different device which had different serial number and password also different?

Also, what if I replace shadow file in /etc/shadow with another from previous version of mmcblk0p2.img with mario password? Will it work?

Yes.
You only have to replace the first line, the "root: ..." line.
Be careful to use an editor set for 'lf' line endings.

I'm thinking about replace file because I can't use the editor (can't acess to shell) . I checked it before update and only first line is different. The hash which I posted to pastebin some time ago was only in mmcblk0p1 partition, but after update this hash appeared in diags partition. I mean "ha4E...". I will try and post the result later.

Who made this images? Maybe he can share with password also?

If you want (or have to) replace the entire file - why not just set the root password to something you know before you copy it over?
Borrow that "root: ..." line from your desktop system.
