Hi, I need a "P-660H-T1 v3s" firmware.
I've already  searched on the zyxel support site but for this modem there aren't any download.

    I don't know, the previous owner flashed a wrong firmware.
    I can reprogram the flash chip directly

    Hi leofante,

    May I know where you bought this device? How about status of this device? Can you login to device?

    “the previous owner flashed a wrong firmware.I can reprogram the flash chip directly”. So it means that you change flash by yourself, but there is no fw image currently, right?

    I didn't bought it, it was given to me hoping I can fix it, I think it was bought in a store several years ago.
    I cannot login in the device via browser.

    Using the serial connector on the board i get this:

    Bootbase Version: VTC_SPI_WR1.10 | 2010/06/23 09:32:52

    I've tried ATUR with fimware from similar models but without success

    Starting XMODEM upload (CRC mode)....
    Total  1284608 bytes received.
    Wrong product firmware!!
    Please upgrade the newest firmware version!!


    as mentioned  before I can also program the flash chip directly with a programmer.

    The problem is that I've been unable to find the correct firmware for this device on any zyxel site

    The log seems come from internal serial port.
    I am just curious how you can get the internal serial log?
