updated os card, now no access, no root or first user pw.

Greetings all;

I have a red pitaya, and I just, after about 18 months, overwrote its 
boot and operating u-sd with about a 4 version newer os and app image.  
Used dd of course.

But the image had no root account pw, and no first user at all.  And it 
runs headless. Running a u-boot, armhf version of ubuntu 16-04 even 
after the update.

So I need to restore enough of the passwd and logins, to at least get a 
first user and valid passwd reset into it?

This thing has no video output, or keyboard input in it and no shell 
access that I can find from its web browser interface that only works 
for the mac address of its ethernet port. So this has to be done by 
putting the card in a reader on some other machine and editing the 
correct files. 

How do I preceed given those restrictions?

Thank you.

Cheers, Gene Heskett.
