how to install a firmware with .p7 extension - jofre - 08-06-2015
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?!!
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
any ideas? flash is not deteced on jtag

Remove the following amount of bytes from the beginning of the file using any decent hex editor:
If Docsis: 1604 bytes
If Euro-Docsis: 1527 bytes

it is not my file, I found it on http://sysadmins.ru/topic247182-15.html
AVG did not find it any viruses

how should I flash all the files?
here's how I'm trying to do
1. flash the 2mb virgin file using ldram/program 9fc00000 200000
2. flash the newer firmware file over the the 2mb - is that right? - using again ldram/program 9fc00000 200000
3. flash haxor with ldram/program 9fc10000 130000
is that correct?

Sysadmins was great until it got the ru domain.. open file with hex and match off with another scource, because I've never known a firmware to flag as virus
Malwarebytes is so commercial I believe even they would start deleting files most DONT need under the guise of 'POTENTIALLY' unwanted programs.. like anti virus's do with modem tools, bios tools etc..
