Xerox 7845 code on the back (on SBC) - 0

[buzzgrafix]

The device was stuck on the green screen saying it is powering on. I did the altboot and successfully reloaded the firmware.
However, after the first reboot it came up to black screen with all lights ON.
The only code I see is the one on the back - red number 0.

Can i use any SD card of the same size and do another ALTBOOT to rewrite it?
Or it needs to be pre-programmed card?

Nevermind, found an image for SD in another thread.
Thank you!

Just wanted to let you know that your advice worked. Got a new SD card, re-imaged it. And then did Altboot again and it is working.
Thank you so much!
