My 5120 was bricked for soooo long until 5 minutes ago. I downloaded the 5120firm.bin dump from the firmware download section, then all i did was this;

Code: Select all

-detect 
 IDCODE 0000100F
 TI TNETC4401
 IMPCODE 21404000
 DMA not supoorted
 Found Address= 90000000 MX29LV161T		
-ldram 90000000 
-sprogram 90000000 200000 
 Program Starts...
 Program time 00:10:50 (.609)
It took 10 minutes to program with sprogram, but after it finished the 5120 rebooted(on its own lol) and it fired up no problems at all, and it is now working!! I would like to thank usbbdm (THANKS SOO MUCH) for the 2mb dump of the 5120 firm, without it I wouldn't have been able to do this!

Oh and btw, I am using a regular usbjtag not an NT.

Use slow clock speed for modem that has wrong boot. Only program the boot and then you can program the rest with normal "program"
