Please, upload the file (e.g. to zshare.net) and post the link in this topic: [DOWNLOAD LINKS] Firmware dumps available

Just uploaded to:

zSHARE - tx-1_dump_080312

And then downloaded file to confirm accuracy. It's fine.

Please note, I did not try to remove any leading or trailing zeros from the file. It is just the raw dump of empty.bin renamed to TX-1_dump_080312.

I'll really look forward to what you 4-star generals come up with from this!

TIA,

OK, I have the dump.

Are there any updated signatures or scripts that I should be aware of for IDA Pro ?

To Microfunguy:

After loading dump in IDA I see why you could not turn on any LED: all of them controlled only with PWM (UniqueLedOn()/UniqueLedOff() functions, no 0x46/0x44 access).

I must be doing something wrong, I only see zeros !

I renamed file TX1.BIN and loaded into IDA.

Gave ROM start address and loading address as 0xFFC00000    .. it did not like that.

Tried leaving the addresses at 0x00000000 and I do not see any code.

Hmmm .. so that is like the 'S', 'SD'  and 'G' series rather than the 'A' series

The 'S' series caused problems with USB-remote but the others were OK.
