MPC 5504 Ex Service Lock and Changed Passwords

[kleankopy]

The one we did last week had a classified sticker on it would not let us in the sp mode and all passwords changed. But the special sp mode worked.
Are you saying you can lock out the special sp mode also???

That's exactly how you did it, which brings me back to my original point

Honestly...Elmo has provided a pretty clear description.
YES, when Service mode lock is on, and all passwords are changed, it would seem that you are basically screwed to put it bluntly.

And you are correct, we've all run into machines that are locked down in a variety of ways including passwords changed, and FACTORY SP (Not Special SP as you refer to it) is how you're able to reset them.....along with also being a quick and easy way to wipe the address book

With every model I have worked on, Service Mode Lock disabled access to all service modes with the exception of Touch Screen Calibration. It used to be taught during instructor lead training.

Restricting a Customer Engineer Operation
You can restrict the customer engineer's access to the service mode.
Service mode is used by a customer engineer for inspection or repair. If you set "Service Mode Lock" to [On], service mode cannot be used unless the machine administrator logs on to the machine and cancels the service mode lock to allow a customer engineer to operate the machine for inspection and repair. This ensures that the inspection and repair are done under the supervision of the machine administrator.

1. Log in as the machine administrator from the control panel.
2. Press [System Settings].
3. Press [Administrator Tools].
4. Press [ Next] twice.
5. Press [Service Mode Lock].
6. Press [On], and then press [OK].
You will get a warning 'This machine cannot be restored by service after service mode is locked. Are you sure you want to continue?'
7. Press [Yes].

Remember, you have to be logged in as the "machine administrator" to even see the Service Mode Lock on some models.

8. Log out.

How to do a forced start up with no encryption key
If the encryption key back-up has been lost, follow the procedure below to do a forced start-up.
• The HDD will be formatted after the forced start-up.
• Encrypted data will be deleted.
• User settings will be cleared.
1. Prepare an SD card.
2. Create a directory named "restore_key" inside the root directory of the SD card. Then,
save the "nvram_key.txt" file using the following name:
/restore_key/nvram_key.txt
3. Create a text file and write "nvclear".
• Write this string at the head of the file.
• Use all lower-case letters.
• Do not use quotation marks or blank spaces.

• It is judged that a forced start has been selected when the content of "nvclear" is executed and
the machine shifts to the alternate system (forced start).
4. Confirm that a message is displayed on the LCD telling to insert the SD card that contains
the encryption key.
5. Turn off the main power.
6. Insert the SD card that contains the encryption key into SD card slot 2 (the lower slot).
7. Turn ON the main power.
The machine automatically clear the HDD encryption.
8. Turn OFF the main power when the machine has returned to normal status.

This should reset the admin and supervisor passwords allowing you to enter User Tools, switch off service mode lock and then do what you need to do.

To the thread poster.
it is possible to read passwords thru eeprom reader dump.
Just NVRAM1 is needed.
If you can provide that file (256kb) maybe i can do something.

Can’t dump nvram if you can’t get into SP mode, read the entire thread.

Read what i wrote too maybe.

I agree with davel, READ THE ENTIRE THREAD. In the second post of the thread I posted

you then need to find an adapter for 8 pin NVRam devices and software that works with it. Be ready to spend somewhere between $800.00 and $3,000.00. If somehow you are able to get the hardware and software needed you then need to determine where the supervisor password is stored.

Now exactly how do you propose the original poster obtains that 256K data file?

Just extract SPI Chip from the controller and choose FM25LV020 from the dropdown menu. Read.
Send me the 256kb bin file.


And please remember: in the past i've made a program to decrypt Ricoh passwords and gave to the mighty Paul.
So i may know what i'm talking about

We simply replace the NVRam with a new one when faced with this issue.
