Hello to all.
I need help to recover a SP20.
problem happens when i downgrade from 2.6.14 to 2.5.12 with firmware list from web management. After the downgrade machine shows it is a SP10, having web access, but not mining. I did a factory reset and have not more access to the unit.
So I tried a recovery with SDcard. I got xmas lights , but problem remain. 4 times or more.
I can get web and ssh acces to the machine with SDboot, but want to recover internal memory.
It looks that something internally is saying the machine is a SP10 , but doesnt know how to change it.
here is something similar:

but i am not sure if this is the same that my situation and what the instructions to fix it have to be implemented.

I write to support, but I get tired after one week waiting for a solution from them. Not much happy with support.

thanks

Did the same thing when I first got one of my SP20 units. It takes a while after you get the xmas lights. Just let it go about 5 minutes. After that, immediately flash with new firmware. Be sure to use the recovery and not boot SD. Worst case scenario, SP-T will remote with you to get it going again.
