Hi all,
I'm new to the forum, so please bear with me. I've had a browse through, and it seems the info I need is not posted in the forums, but often share in private so I'm hoping I can tap some knowledge and get to where I need to be.

I have a 7200 system with an MP20S processor card installed. I have the IP address details and the Tech Prog Passcode (MMC800). MMC727 tells me the software version is MP20S-SYS VERS '17.02.28 V5.01. The detail I don't have is the admin password for the Installation Tool.

So far I've tried:
- press the RST button - doesn't reset passcodes/passwords
- System Restart with Clear Memory - doesn't reset passcodes/passwords
- Browsed a million forums - no information
- Found instructions involving a specific set of MMC commands around 505, the speaker button, 900 and some other numbers. Didn't work.

I've seen some info regarding possibly gaining access through the SIO port and entering some commands in the Linux shell there, but again no detailed info online about this. I have access through the SIO port, but don't know what specific commands I would need to enter in order to gain access.

I'm not interested in seeing the current setup of this system - I simply want to factory reset and restore a backup of config I have from another broken system (I bought this one as a cheap temporary replacement for the broken one).

Is anyone willing and able to share relevant info with me that doesn't involve speaking with Samsung or a support company (because I have no relationship with either of these)?

Thank you
James
