That message means it can't find your hard drive (or any other boot device).
Common steps- review directions for any specific switch settings needed, contact LTG , try another USB stick

I'm on it.

He'll update. Right now pointing to a USB stick that is bigger than the 8GB to 16GB recommended.

I hope he gets it going to start the New Year right.

LTG : )

Not sure if this will work for you but I think I had a similar issue years back. At the time I was using the JJP recommended program to create the ISO on the thumb drive, didn't work. I ended up using Rufus below to create the ISO on the thumb drive and it worked great. You could try formatting your thumb drive and then create a new bootable thumb drive using Rufus.

With my JJP pin they have there own USB that’s never had anything else on them.
It’s the only way it ever works for me.
Start with a brand new USB

I dont have a WOZ, but i know computers. Sounds like it installed the OS back onto the USB. I would start over with a clean ISO boot USB and also check the cables on the hard drive. Unplug and re-plug in the hard drive cables both at the hard drive and where it plugs into the board. I would actually try to get the system to find the hard drive first before upgrading. Hope this helps and you get it figured out.

Had a couple thoughts late last night.

When you do this - download update - open unetbootin and use that to put update on USB stick - game turned off plug USB stick into cable by cashbox - turn game on. Just checking if you followed those steps. You may have.

If you did all that. I wonder if your SSD is bad ? If you have one, I'd stick it in, then upload the software like a full install. See if that works.

You can connect a keyboard to a USB port on the motherboard and use that to get in like you would any other computer. If the instructions aren’t in Butch Peel’s legendary manual look up the motherboard model online or post a photo showing it and we’ll help you look it up.

When you removed the battery you reset all the BIOS settings to their factory default. You'll have to go back into the settings and tell it to turn on after power loss again.

But to answer your question, yes. It it POSSIBLE that the battery is dead. Unlikely, but possible. Test it with your meter to find out.

Look at page E-13 in your manual.

Ok, nevermind. E-14 says, "Note: If your game’s CPU battery discharges below 3V (or if you remove the battery) while the game is
turned off, all BIOS settings will return to factory defaults. As a result, your game will not boot properly the
next time you attempt to power it up. In this case, contact JJP® technical support for assistance in restoring
your CPU BIOS settings and getting your game to successfully boot again."

Not helpful at all.

For future people reading the motherboard is an MSI H81M-P33
You can download a manual here: https://us.msi.com/Motherboard/H81M-P33/support#down-manual
It doesn't explain in the manual exactly what the setting is to turn the game back on after power off but megaladon has some screenshots that show which one it is.

The splash screen is the motherboard is working.

So update or SSD has the issue. ( I had one failed on DI, I stuck in a HP 120GB SSD and did the full install and worked great. Other than any settings I changed I had to change back and audits and scores etc. were gone.

LTG : )

That I/O error during partclone means that either the USB stick or the SSD shit the bed and stopped responding. If you've tried different USB sticks, almost certainly the SSD is dying/dead.

Edit: Looks like the USB stick went offline based on the I/O error. Maybe try a new USB stick AND plugging straight into the motherboard, bypassing the extension cable in the cabinet.

Hi, happy new year, this really scares me from upgrading any of my jpp pinball ( Wizard of Oz The Hobbit Pirates of the Caribbean
) even though I probably won’t resist if the Potc code ever get released. Good luck to you in your debug process

Oh shit!!! Sure regretting updating to 7.04 now. It was working fine on 7.02 and now it wont run. I get the JJ splash screen, and then just a constant black screen. No text or GUI...nothing.

Followed the directions to the letter. The machine the update was done and to pull the thumbdrive and restart.
Now what?

Assuming you're not willing/capable of pulling the SSD and verifying it's functional, step one is run the full update again.

How do I get the screen to run update again? I cant get to any screen at all. Just a solid black screen is all I see.

Hey guys I still dont understand how to run the update again. I have a totally black screen as shown below. Where specifically do I go from here? And I can pull the drive if I need to.

Those are two different things.

Your pin contains a computer. That computer has a motherboard. When you turn on your pin, the motherboard does a POST- Power On Self Test. If it doesn't pass it MAY do nothing- no beep, no splash screen, just remain totally black. Or it may give some indication of the problem. Have to look up your motherboard and read the manual or ask JJP.

If it passes POST it hands off control to the boot device. That could be your SSD, a USB stick, whatever device you've chosen as your boot device. JJP might set the motherboard to check USB first and if no boot device is connected to a USB slot check the SSD. They might also set it to boot the SSD in all cases and the SSD checks to see if a USB stick is present with an update.

I would disconnect the SSD if I were you. Should get a message about no boot device found. If you don't get that message your motherboard isn't passing the Power On Self Test.

If you're getting ONLY a black screen check your video cable(s).

JJP tech support is going to be your best option. Consider the owner's thread too. Someone with a Wizard of Oz is more likely to have specific test results for you than general computer advice.

Okay I found the full install file at their support site. Its up and running now. Thanks all.
