-ldram boot

-erase boot
Erase starts...
so then I sprogram boot and nothing continues to happen
Code: Select all
-sprogram boot
Program Starts...
Any help would be appreciated. Thank you
I have a full flash, wouldn't the full flash contain the boot??? Or is it in a different memory region. I am trying to debrick this modem then flash over a differnt SBV5220's full flash, that would be a copy/clone correct?
