I used NAND programmer and read back the flash. If anyone needs to analyze the dump, please let me know, the file is 135MB and 94MB after zipped.

I am not sure what happened to my board. I soldered TWO serial port (On Atom, on ARM), I found non of them works.
I also do not see any LED blinking. Could be a dead board.

i'm wondering about these modems now that firmware is out and 2 options for accessing them.

1. SD SNIFFER
2. JTAG DEVICE
- im wondering if we can use a 360 CLIP to do read/write the nand
- the nand is protected in some way.

The XBOX NAND should have a build in NAND controller which convert NAND bus to SPI protocol.
If the NAND bus is direct connect to the CPU then this method should not work.
The best option would still be using JTAG.

You want to do ISP?
There are two videos already. Check youtube video.
The ISP pin for TM1602 is on chip U402 (TSP54328).
Solder short wire pin1 to ground. (Pin4 on J3 or pin4 on J4).
Power the modem with regular 110v. Use u-link Nand to detect the flash.
I hope you can get something back. You might not be able to get the flash (needs to be defined).

I'd like the correct point info to use all around my chips they have different digits basically no J3 or J4 or maybe I'm overlooking something this is a newer revision I'd guess of the TM1602 w/ the A added at the end. Forums and diagrams work best for me as I'm hearing impaired and the closed captioning feature on youtube rarely gets it right but thanks for this cool device! It's going to help me out lots! :-)
