Has anyone tried loading the Z-stack Zibgee 3.0 coordinator firmware into a Zigbee2mqtt Dongle Plus Smart Home Stick? It’s got the high power CC2652P Zigbee chip and the Silicon Labs CP2102N USB-to-serial interface chip in it.

I downloaded the TI Flash Programmer 2 software and tried to load the Z-Stack firmware into it via the USB-serial interface. I successfully loaded the Silicon Labs CP2102N Windows chip driver and Windows recognized it as a serial port on COM3.

The Flash Programmer 2 software DOES allow me to read the MAC address and read the Info Page data, after the RESET + K1 switch combination.
But, it won’t go into Bootloader mode and load new firmware after the the RESET + K1 switch sequence (which is supposed to put the CC2652P into bootloader mode).

The seller’s instruction for bootloader mode is:
“after connecting the USB, press and hold the RESET button, press and hold KEY1, then release the RESET, and then release the KEY1 button, then the device will enter the BOOTLOAD mode.”

I guess no one has tried this device before!
I gave up on it and returned it to Amazon for a refund.

Dang, I have the same issue. No way to enter bootloader mode.
Did you really give up or did you manage to do it?

I gave up and returned mine to Amazon before I found a way to do it.

There’s a very specific list of steps and software needed.

Mine is coming from aliexpress, no way to return it.
15,87€ temporarily wasted. Unless I buy the XDS110 they are mentioning.
Or if someone finally found the way to activate the bootloader mode.

The Python guide did not work.
It can read the memory, no problem but can’t write.

Maybe over time someone will find the solution, that day I’ll remove the dust from it and convert to a router probably as I’ll buy another one as coordinator.
