Is the 5120 even worth the hassle? - modembricker - 30-11-2013
After shooting my mouth off about how easy it is to mod a surfboard modem, a friend of mine asked me to mod his SB so i open the box and its a 5120. I then proceed blindly into flashing it with my USBJTAGNT assuming it was similar to a 5101. I was wrong. I bricked the modem and and reading about the watchdog. The chip is detectable but I just dont have the patience to give it another go after reading how shitty these modems are.
Is there a better way to go about this, or should I just throw this thing away and concentrate on the 5101N I have laying around.

Backup firmware
getram 90000000 200000
save 90000000 200000
Disable watchdog be ready to program
SB5120 has a watchdog and need to disable to do programming.
Create file named 5120p.usp
reset
detect
program
Type command 5120p
After this your SB5120 is ready to program and you can program it in normal speed without trigger watchdog.
Program whole firmware.
ldram 90000000
program 90000000 200000
You can use "reset" to restart the modem. You can not use "cmpram" command to check if the programming is ok when it says "DEBUG ON"
Rescue SB5120. When box not fire up. Normal programming will not work. First need to program boot. No watchdog exist in this case
detect
ldram boot (Select proper boot file)
erase boot
sprogram boot (Slow programming)
reset
detect
ldram image0(Any tabes you have backed up)
program image0(Any tabs you want at normal speed)
getram 90000000 200000
save 90000000 200000

Forgive my ignorance but I am perplexed at the part where I create a file 5120p.usp
Do I literally create a text document and type
reset
detect
program
then name it as such and change the extension to .usp?
