Firmware has NOTHING TO DO with Detecting FLASH......auroden wrote:I tried that and no change, the flash type is still unknown.
I was able to initialize the Ethernet port via serial console and downgraded the firmware to 3.0.1 from a TFTP server. That didn't change anything regarding the flash recognition.

Flash Detection not necessary
It turned out I don't really need to detect the flash type since the serial console (RS232 to TTL) does everything that one needs to unlock and program this V-Portal. The serial pin header is there, no need to solder JTAG connection. I successfully unlocked the device and programmed it for other VOIP providers. The credit goes to http://voipfan.net/ where one can find a complete tutorial for unlocking and programming lots of different VOIP adapters.

I am still interested in seeing you do a real JTAG.auroden wrote:It turned out I don't really need to detect the flash type since the serial console (RS232 to TTL) does everything that one needs to unlock and program this V-Portal.

That's a bold statement in a thread about VDV21. Could you be SO kind to provide required Interactive voice Response (IVR) commands and IVR User password(s)? For example, the command to erase the admin password or see it on Vonage display, since not every VDV21 adapter allows FW change via TFTP server as described in the Tut you linked above.merkin wrote: My locked voip devices were easily unlocked via IVR. No need to open up.

In no way you will get the password shown on the display
Every VDV21 will let you replace the FW if configured properly. The IP assignment is a little bit tricky but eventually works.viski37 wrote:... not every VDV21 adapter allows FW change via TFTP server ....
Look for the static password in these memo locations: BF3D00FA; BF3D00FE; BF3D0102 or BF7F0118; BF7F011C; BF7F0120
You need to carefully read and understand the tutorial described on the website mentioned before.
It is not easy but it is doable and if you are patient and detail oriented you will succeed.
