    Apple Watch Charging Controller Schematics / Boardview - 820-02601
    by a_p3rson
    Hi there,

    I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.

    You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.
    This daughterboard uses an interesting...

    Case study: apple A1311 firmware locked
    by iacopo
    A client brought in a IMAC A1311 that had been firmware locked and said he forgot the password.

    I fixed the problem by reading the ROM and removing the part where it enabled the firmware lock and rewriting it to the MAC.

    In my case this is what i did: i search for the string of text "$SVS" inside the dump, and found there were two, the first one was followed by a lot of non 0xFF bytes, the second one instead was followed by only a few non 0xFF bytes.

    What i did to fix it was copy the second apperance of "$SVS" along with all the...

    Ubiquiti firmware help. US-8-150W POE
    by gurj1979
    Hi guys.

    I've got a Ubiquiti US-8-150W POE switch which has issues with updating the firmware.
    Turned out to be a bad EEPROM chip. It would read the firmware and work as normal, but failed to write new firmware to it.

    So I took off the chip and read on EEPROM and saved it. Wrote to old chip and failed to write
    Got New chip and writes good.

    THE PROBLEM...
    It fails to fully load the firmware, POE lights fail to work during g firmware test during load. I'm suspecting bad EEPROM Read.

    Does anyone have a Good Firmware I can have?...
