Firmware has gone bad on SPA9000 V1

[masterx81]

Hi to all... My name is Enrico, and this is my first post...
I've a SPA9000 v1, firmware 3.2.3(d), and i've tryed to configure it with the lastest wizard application, but after the configuration, the unit doesn't respond anymore, and i can't neither reset the configurtion via a phone connected, as it keeps rebooting itself every 4 secs. Seem that the wizard application has in some ways broken the firmware.
The cisco community forums have declared dead the device, but i can't RMA it. So i've tryied to desolder the flash chip and read the content (i've a programmer that can read that type of flash), with the hope to upgrade manually the firmware, or reset the configuration, or at least do something for take back to life.
I wasn't able to find the original 3.2.3(d) firmware, so a direct comparison of the firmware loaded on the flash vs a bin update file (present in the update packet distributed by cisco/linksys/sipura) it's impossible.
Comparing the flash with a 3.2.5 version seem that are quite different...
Maybe the bin file isn't directly loaded 'as is' on the flash chip, surely it's saved at on offset on the flash (the first part of the flash seem something like a bootloader).

Maybe i can try to understand how the cpu read the content of the flash (i know a little bit of asm and microprocessor low level programming), but i dont' know what type of cpu there is inside (it's a proprietary sipura cpu, not know the instruction set), and doing it in this way will be a very long mode to repare it.
The fastest way to repair it is to read the whole content of an another v1 spa9000 hardware and copy it to my flash chip.

Someone have some suggestions? Or know where i can find a 3.2.3(d) firmware for a better direct comparison??

Really thanks!!!
