One thing I noticed that strange was my Kindle S/N start with "90D4" not same as what I saw in other topics.

Thank you!
I presume you mean in the "main" system (the only one replaced by an update).
Since the update is a complete replacement of the system files, your /etc/passwd and /etc/shadow files have also been replaced.
And that means your 'root' username on the "main" system is now set to dis-allow password logins.
The password for your 'root' username on the "diags" system has not changed.

Since you where jailbroken before, check if you are still jailbroken.
And/Or
Just run the 'hotfix' script just to be sure.

Then you will have to re-install everything you had installed - just the same as any other full image update.

Only now, since your on firmware 5.6.x series, you have to use the Mobileread Package Installer (MrPI).
Which is an extension for the KUAL menu - so you have to have that installed also.

Get all of your packages from NuLuJe's "snapshot" thread.

You didn't mention what way you are trying to access your Kindle.
Over the USB cable? Over Wifi? From a Kindle terminal?
Using ssh? Using telnet?

Duh ....
There is a lot of information you failed to include.

So just ignore the failure to supply enough information to give a short, specific answer.
Do all of the following:
Hotfix your jail break -
Install Kual -
Install MrPI -
Install USB network -
Enable it (it installs KUAL menu items for that purpose) -
Use TelNet over the USB cable to access your Kindle (TelNet over the USB cable does not require a password - it is modified for just this purpose).
