SUCCESS for the factory image installation!!

I took the micro sd card and used a different adapter and re-imaged the card on my ubuntu. I removed and reinserted the sd card. Now I get one of the 2 file system to mount!!!

Next I reinserted it into the SG-1000 with the SD BOOT jumper in place. Then powered it up with the console cable active.

This worked! After a long stream of messages it finally stopped where it reported:
This will install the standard firmware and will erase all the existing contents of eMMC permanently.
eMMC device: mmcsd1
Are you sure you want to continue ? (y/N)

answering y then proceeded to performing the firmware installation and then it shutdown.

I removed the SD BOOT jumper and the sd card. Then I powered it back up.

It then came up to the proper version used for the re-imaging and I was able to begin to configure the device.

The web gui now reports:
Version 2.4.3_1 is available.

SUCCESS
