I can't flash the Sber smart light bulb

[zahar2308]

Hello, I can't flash the Sber LED GX5 smart bulb. When I try to flash it, I get the following error: "Trying to read encryption key..."
Encryption key read done!
Encryption key: 00000000 00000000 00000000 00000000
^^^^^^^^^^^^^^^^^^^^^^^
WARNING! Non-standard encryption key!
If it's all zero, it may also mean that read is disabled.
Please report to forum https://www.elektroda.com/rtvforum/forum51.html
Or just try using BK7231M mode
^^^^^^^^^^^^^^^^^^^^^^^
I'm flashing with the firmware https://github.com/Brokly/ESPHOME_SBER_SBDV-00115

You need to give more details on what you're flashing and with what tools.

The repo you linked doesn't just contain "firmware", but ESPHome YAML configuration and OpenBeken BIN file for some reason. Again, it's unclear as to what you're flashing.

The error you posted comes from one of OpenBeken's tools, we don't provide support for those here. LibreTiny's flashing tool is ltchiptool.

I'm flashing a device: a smart LED g53 bulb from sber, based on the bk7321N chip and the bp2571 driver. I've tried flashing it using programs like BK7231GUIFlashTool-v50 and ltcchiptool-v4.12.1. I'm using the OpenBK7231N_QIO_1.18.165 firmware.

So you're trying to flash OpenBeken. It's unrelated to LibreTiny and we don't provide help for this firmware.

Try using ESPHome if you're having issues with OpenBeken. Note that you will most likely use a custom encryption key, see issue #132.
