    Bulb Firmware Update Attempt to Tasmota 8.5.1 Bricked

    カテゴリー: Light

    Bulb stop responding after firmware upgrade to Tasmota 8.5.1. No WiFi accesspoint fallback seen.


    Is there a way to force WiFi accesspoint mode and firmware upload to the bulb when is in this mode?

    I bricked one of my bulbs that had tasmota on it. Is it possible to flash it form the pin header that is on the top of the PCB?

    The update of my bulbs to Tasmota 9.4.0 worked with no issue - all functionality still there 🙄

    I risked the update on a 3 gang wall switch. Bricked. It kept turning the first relay on and off forever, no recovery. power cycle didn't work. I am looking to flash it from serial now... anyone know what the labels on the pin out refer to? I have vcc and gnd, which are easy, then K1, K2, K3, and NC. Not sure how they would traslate to RX/TX and gpio...

    found tx and rx, they were just a little ways away and I am apprently blind. I can't make it go to flash made though, i need to pull gpio1 to gnd, I think, but don't have a gpio1... I am kicking myself because it was basically working, and I just wanted to update it before i set it up... guess i got an old one.

    Hi, thanks for the feedback - I´m aware how to upgrade - no issue with that. I was just wondering if: a.) there was a way to be sure I´m not on a device using the old bootloader, bricking the device when uploading b.) Anybody has tried to upgrade to current version 9.4 succcessfully with a Athom LED bulb Thanks - MacS

    Hello, my Athom LED lamp is on Tasmota 8.5.0(tasmota), how can I identify if it is safe to flash to the latest Tasmota version? I have bought it early this year - so I would think it should be OK.

    I would need to update as the HUE emulation in Tasmota is broken and only fixed as of version 9.3.1 of Tasmota ...

    Follow the usual upgrade path from Tasmota. See https://tasmota.github.io/docs/Upgrading/

    Hello, is there any way to flash from the 8 pin header that is visible when opening the bulb?

    I am in cotact with Peter (Athom CEO). Good news. Athom will change to a full compatible Tasmota build. So soon no danger to brick a device when updating.

    Athom reacted fast to the feedback of the Tasmota community! :-)

    Fast Power Cycle Recovery never worked, so I had to disassemble the bulb (hot air gun a necessity to soften the glue, especially between the housing and LEDs' metal platform).


    Luckily, the GND, VCC, TX, RX, REST, GPIO0 are mostly well marked and very accessible once the AJW-05_8285 board in the bulb was desoldered detached for access. Here is what had to be done:




    Also, thank you @athom for the pinout info on the AJW-05_8285 board in this thread:

    https://www.athom.tech/forum/light/how-to-recover-from-correct-ssid-but-wrong-wifi-password-on-initial-setup-of-athom-rgbw-bulb


    Recap:

    OTA flashed with tasmota-minimal, then my own custom tasmota.bin.gz. This bricked the bulb (due to Athom's use of memory that's different from Tasmota's use). No recovery steps worked, had to access serial ports via points on AJW-05_8285 board board after desoldering it from bulb, then flash erase then program with my custom tasmota.bin. Resolder and reassemble to get working bulb on custom Tasmota build.


    To avoid this bricking (and subsequent serial flashing work), don't OTA flash from Athom firmware to tasmota-minimal. Go straight to released pre-build tasmota.bin, console "reset 5", then OTA flash custom Tasmota as needed.

    Thanks Jason. I will keep trying Fast Power Cycle Device Recovery, but am not optimistic.


    Athom Tech, would you provide serial flash pinout to the bulb? It looks like the connectors are there and accessible once just the bulb cover is removed.

    The reason for this is the 2M build linker script (not supported) used.

    Original Tasmota is built with 1M no SPIFFS. Using a different variant will

    result in a brick when using orig. Tasmota version for upgrade.

    It will be just luck when device recovers with Fast Power Cycle Device Recovery procedure


    To say it crystal clear, the issue is generated from the Athom firmware variant.

    Tried "Fast Power Cycle Device Recovery" at: https://tasmota.github.io/docs/Device-Recovery/

    This did not work. Will be trying serial reflash next...


    Any hint as to how to serial flash this device?


    Looks like the GPIO pins are exposed. Would you have the pinouts? Need GND, VCC, TX, RX at minimum, and GPIOs would be wonderful!


    Thanks!
