I have been fighting this problem off-and-on for more than a year.
I'm working with an ARRIS TM502g voip modem
If I slow program (3000000Hz) the bricked unit it seems to load the boot file OK.
If I immediately do an SCMPRAM it shows OK.
But after a modem power reset the firmware always reverts to the same garbage I started with.
The bottom line seems to be I can't ERASE or WRITE to the device.
I first posted about this 2 years ago. (Arris brick!)
I tried the suggestions given at the time.
I can't think of anything else I can do on my own.
Perhaps sometime you could do the Teamviewer thing and take a look.
Thanx!
USBBDM please help!

If scmpram was OK then you should be able to get to TRAP ON. Make sure your boot is a good backup first.
