ZP100 not booting

Hi,

I've recently acquired a ZP100 however it looks to be stuck in the boot process with a single white light flashing endlessly.

It doesn't appear responsive to holding the mute button on bootup. On powerup all of the network port light flash briefly and the connection lights are solid if wired to bridge via ethernet.

I know this is an old product and I know it is my fault for purchasing it, but is there any other reset tricks or way to update the firmware to get out of this loop?

    no...once unit is auto booted properly with DHCP from your router, telnetd is disable.

    hey. just out of a curiosity:
    does anybody know if a play 3 unit can be revived the same way we do with zp100? does it have a uart port?

    thanks!

    Play 5 has one. https://sites.google.com/site/sonosdebug/serial-port

    Zp80 has one as well. So very good chance that UART port are common across all Sonos hardware board.

    All the sudden I lost connection to the ZP100 that was recovered through upgrading the diag firmware.

    It was working and running fine, but now it start to act up. The Sonos app just lost/drop it from the device list. Trying to add it again, but still won't show up.

    Connecting to UART, the auto boot seem to get executed properly.
    Rincon boot loader version 1.0-27270(ZP) (32M SDRAM). Press 'h' for help.
    SDRAM test...
    Memory test iteration 0
    SDRAM test complete
    Attempting to autoboot from NAND device
    NAND ID is EC:75
    32M NAND flash (Samsung K9F5608U0C) detected
    Section 0 is provisionally good, kernel on partition 1, generation 9
    Section 1 is provisionally good, kernel on partition 4, generation 8
    Attempting to boot kernel from partition 1

    but I can't see any IP Address assigned from the router. And I can't ping the 169.254.1.1 either.
    What could be causing this?

    I tried hitting the 'h' to get to bool loader menu. I did run the SDRAM test and it goes for 100+ time, it seems to come back with no problem.

    Something very very similar happened to my revived unit. I ended up opening it and cleaning all the electric contacts and cables. I moved everything inside it.
    After that, I hard resetted the unit and went back from death.
    Hope it helps. Please report any news if you can.

    What is "hard reset"?

    Sorry. Should've said factory reset.

    Tried all that. no budge. Something got to give. Ethernet port appear to be engaging with LED flashing. So there are some IP activity going on.

    if you hardwire the unit to your router, what do you get when running arp -a in any network device?
