RE: Help, SB5120 bad need certs to clone to my Haxorware modem - CableGuRu - 07-07-2012
I am not sure how to do that at all. I am using the parallel JTAG cable. Is there anything else I can do to try and get this?
*EDIT* Thank you. I think I can do it by the pic you posted.

here's a correct def that i knocked up but (a big BUTT) i have no idea what processor or flash chip is in a 5120 (mostly because i can not be bothered looking) and even then the risk of using this def would still be very risky as it is untested
Code:

thank you. I tried using that def file. what I did was copy the folder "bcm3349" to the Hitachi Dir in the "jtagparts" folder. Then I edited the file "PARTS" to include "0x0000100f, bcm3349, BCM3349", I then got this:

The bin file was 8mb of empty. it was instant too so it didnt read it. I do have a rs232 board. Is there another way I can get the certs?

well to me it looks like the def is working and that the flash.def is missing something
what flash chip is in your modem

I found this: http://www.usbjtag.com/jtagdevices/sb5120.php I gives info on the cpu and flash.
The Flash chip is: Flash Memory PC CHIP 29LV160BTTC-70 MX brand TSOP48
RE: Help, SB5120 bad need certs to clone to my Haxorware modem - drewmerc - 08-07-2012
well after looking at the flash def i know i don't have much of a clue as to what's going on and i don't really wish to learn
(but looking back at the above can i ask why your using 5101 addresses when trying to getram? you should be using 5120 address
>getram 90000000 800000
or
>getram 94000000 800000
or perhaps just try getting the certs/nonvol
>getram nvram0
>getram certs
but i do find usbjtags sb5120 link interesting as it shows how to bypass the watchdog (again all the above is speculation)
RE: Help, SB5120 bad need certs to clone to my Haxorware modem - CableGuRu - 08-07-2012
I tried the commands you also gave and it does not want to dump the flash. I was hoping that I could somehow use the rs232 board and get the info somehow. I thought there was a method but I am unsure. I may just have to hook my old modem back up and fight through the pain till I can get another one. Getting lots of lag and not getting lots of lag using a friends modem. Signal is great. And speeds look fine on speedtest.net with my old modem. Was hoping to have my haxorware flashed modem to use in its place though.

you can try with you max cable the connections are in the pic posted, extracting the nonvol from it is going to be fun (assuming the bootloader is noisy)
RE: Help, SB5120 bad need certs to clone to my Haxorware modem - CableGuRu - 08-07-2012
ok. I just flashed my modem back to stock. I am going to have them add my modem to the account since it is stock again. Is there any benefit nowadays to having haxorware on a modem if using it on your account with standard assigned bootfile?
Also what command do I use to grab my nonvol from the 2mb dump on my modem?
Thank you a lot for all your help btw. It has been over a year since I messed with modems.
