    Hi,
    I’ve (actually my dad, I set it up for him) been using opensprinkler v2.2 (bought fully assembled) for over a year without issues. A month back, he complained that it was no longer working – the HTTP connections used to hang. I tried to reset it, but no luck.

    I saw that a new firmware was out and decided to flash it. I downloaded the updater and tried updating the FW. It says
    verification error, first mismatch at byte 0x0000
    0x0c != 0x62
    verification error; content mismatch

    Full log attached. Any pointers is appreciated. 🙂

    OS: Win 10

    There may have been some sort of flash memory corruption. Can you submit a support ticket? We probably need to reflash the microcontroller (not through the USB port, but through the ISP pin headers).

    Ray,
    Sure, I will submit a support ticket as soon as I am home (in another 8 hours). I am in India, so should I be buying a USBASP or USBTiny in anticipation?

    Regards, Jithin

    Ray, the device is now in India. Its gonna take a fair amount of time and money to ship it back to you.

    I opened it up today and i think the ISP headers under the LCD, right? Please send me the instructions and I’ll try to do it myself.

    Regards, Jithin
