how to install a firmware with .p7 extension
#1
Hi folks

So i decided to bring some old dead modems to life - magjack fried during a thunderstorm and i was not able to access 192.168.100.1

I managed to re-flash it, it's a sb5101, but my ethernet port is dead, so all I have left is the usb port - which will not work on x64 windows system - unless - it's newer firmware

So the question is: how can I update the firmware using a .p7 file?

I read there's a way to remove the header and rename it to .bin but I don't know how to do it

it needs to be SB5101-2.8.3.0-GA-01-455 or above

I flashed I virgin 2mb file before installing haxor

I have newer firmware files but I'm not sure how to proceed - the files are not 2mb in size (smaller), should I flash the firmware files OVER the 2mb virgin dump or can I flash the firmware and then haxor?!! Huh



thank you

btw, one of the modems is really f**d up. I´m trying to hard debrick it, short circuiting with the 3.3v techinique but things are not pretty...all lights blinking at the same time Confused any ideas? flash is not deteced on jtag
